Emerging Market Firms’ Response to U.S. Economic Recession and the Subsequent Period’s Performance
Authors: Hahn TeWhan , Chinta Ravi
Published: November 2021

We investigated the changes in behaviors of firms in emerging markets in response to the U.S. economic recession and the impact of those changes in strategic behaviors on subsequent periods’ operating performances. Specifically, we adopted an event-study methodology, using a sample of emerging market firms, to investigate the nature of the effects of the U.S. economic recession on firms in emerging markets. Based on 5,887 firms in nine emerging countries, our results show that firms in emerging markets exhibit changes in strategy variables, and those changes have a significant effect on the subsequent periods’ operating performance. In addition, we found that the impact of changes in strategy variables on the subsequent periods’ operating performance is stronger among more resource-unconstrained firms than among more resource-constrained firms. We ascribe this latter finding to the lack of slack resources that are necessary to make changes in strategy variables during the aftermath of the global economic recession for more resource-constrained firms.
Community as a Sustaining Force: Strategies for Online Scholarly Support
Authors: Mullinix Bonnie , Binger Alison , Lees Michael
Published: November 2021

This paper discusses the ways that community connections serve to sustain and support scholarly growth, retention, and success, particularly in longer-term online contexts. These strategies are seen through the reflective experience of a faculty mentor and two recent graduates who co-developed community support strategies that help doctoral students stay motivated, connected, and succeed over many years of what might otherwise be a long, individual, and lonely journey—particularly when undertaken online. A matrix of strategies, apps, and online tools emerged from this process and is offered for consideration.
Predicting Students' Spiritual and Religious Competence Based on Supervisor Practices and Institutional Attendance
Authors: Secor Andrew P , Bridges Corinne W
Published: November 2021

Counseling students report a lack of competence in spiritual and religious integration (SRI). As such, counselor educators and supervisors (CES) and students want to understand how to develop SRI competence. Although past research highlights SRI dialogue in training, there exists no clear understanding about the role of faculty supervisor SRI on perceived student competence. The supervision models used to inform the study included (a) the integrated developmental model, (b) the discrimination model, and (c) the spirituality in supervision model (SACRED). The purpose of this study is to determine if master’s-level graduate counseling student perceptions of faculty supervisor SRI practices predicts student perceived spiritual competence when considering attendance in faith-based and non-faith-based institutions accredited by the Council for Accreditation of Counseling and Related Education Programs (CACREP). A review of existing literature supports the use of a quantitative, cross-sectional design. An online survey was distributed to students (n = 59) in master’s-level CACREP counseling programs, currently in field experience, to measure perceived SRI in supervision and perceived SRI competence. A multiple linear regression reveals a statistically significant predictive relationship between supervisor SRI and perceived student competence as measured by the Spiritual and Religious Competence Assessment and the Spiritual Issues in Supervision Scale. These results inform CES about the importance of SRI and student ability to work with the spiritual and religious beliefs of clients. On this basis, it is recommended that supervisors focus on SRI in supervision. Future research should focus on additional factors related to SRI competence during counselor training.
Bearing capacity of embedded and skirted E-shaped footing on layered sand
Authors: Nazeer S. , Dutta R.K.
Published: November 2021

Purpose: The purpose of this study is to investigate the ultimate bearing capacity of the embedded and skirted E-shaped footing resting on two layered sand using finite element method. The analysis was carried out by using ABACUS software.
Design/methodology/approach: The numerical study of the ultimate bearing capacity of the embedded and skirted E-shaped footing resting on layered sand and subjected to vertical load was carried out using finite element analysis. The layered sand was having an upper layer of loose sand of thickness H and lower layer was considered as dense sand of infinite depth. The various parameters varied were the friction angle of the upper (30° to 34°) and lower (42° to 46°) layer of sand, the skirt depth (0B, 0.25B, 0.5B and 1B), the embedment depth (0B, 0.25B, 0.5B and 1B) and the thickness (0.5B, 2B and 4B) of the upper sand layer, where B is the width of the square footing.
Findings: The ultimate bearing capacity was higher for the skirted E-shaped footing followed by embedded E-shaped footing and unskirted E-shaped footing in this order for all combinations of variables studied. The improvement in the ultimate bearing capacity for the skirted E-shaped footing in comparison to the embedded E-shaped footing was in the range of 0.31 % to 61.13 %, 30.5 % to 146.31 % and 73.26 % to 282.38% corresponding to H/B ratios of 0.5, 2.0 and 4.0 respectively. The highest increase (283.38 %) was observed at φ1 =30° and φ2 =46° corresponding to H/B and Ds/B ratio of 4.0 and 1.0 respectively while the increase was lowest (0.31 %) at φ1 =34° and φ2 =46° at H/B ratio of 0.5 and Ds/B ratio of 0.5. For the skirted E-shaped footing, the lateral spread was more as in comparison to the embedded E-shaped footing. The bearing capacity of the skirted footing was equal the sum of bearing capacity of the surface footing, the skin resistance developed around the skirt surfaces and tip resistance of the skirt with coefficient of determination as 0.8739. The highest displacement was found below the unskirted and embedded E-shaped footing, and at the skirt tip in the case of the skirted E-shaped footing. Further, the displacement contours generated supports the observations of the multi-edge embedded and skirted footings regarding the ultimate bearing capacity on layered sands.
Research limitations/implications: The results presented in this paper were based on the numerical study conducted on E shaped footing made from a square footing of size 1.5 m x 1.5 m. However, further validation of the results presented in this paper, is recommended using experimental study conducted on similar size E shaped footing.
Practical implications: The proposed numerical study can be an advantage for the architects designing similar types of super structures requiring similar shaped footings.
Originality/value: No numerical study on embedded and skirted E shaped footing resting on layered sand (loose over dense) were conducted so far. Hence, an attempt was made in this article to estimate the bearing capacity of the same footings.
Quand la pétroarchéologie questionne la notion de site : états de surface et taphonomie des objets lithiques de La Belle-Roche (Sprimont, Prov. de Liège, Belgique)
Authors: DELVIGNE Vincent , FERNANDES Paul , NOIRET Pierre
Published: November 2021

Petro-archaeological analysis of the lithic industry of the Lower Paleolithic of La Belle-Roche cave (Sprimont, Belgium), according to the grids developed in recent years by various research programs in France, allows a new reading of this industry. Although the anthropic character of certain objects seems well-estabilished, their accumulation in the deposit remains problematic. In this respect, the taphonomic and weathering analysis of the industry raises questions about the origin of the deposit, the age of the industry and the notion of “site”: is the “La Belle-Roche site” as a prehistorian or prehistoric construction?

Authors: Machado Miguel , Viecelli Rafaela , Guzati Catherine , Grismado Cristian J. , Teixeira Renato A.
Published: November 2021

A recent phylogenetic analysis has shown that the genus Stephanopis comprises several different lineages of bark-dweller crab spiders. The ones with South American distribution that present a close relationship with other Neotropical genera like Epicadus, Onocolus, Rejanellus and Epicadinus were recovered in a single clade, with good support and stability. Here, we present a taxonomic review of Stephanopis species attributed to the ‘pentacantha clade’, proposing the new genus Kryptochroma Machado gen. nov. to accommodate them. New distribution records are provided and the following species are described for the first time: Kryptochroma gigas Machado & Viecelli gen. et sp. nov., Kryptochroma hilaris Machado & Teixeira gen. et sp. nov., Kryptochroma quadrata Machado & Viecelli sp. nov. and Kryptochroma septata Machado & Teixeira sp. nov. The species Stephanopis borgmeyeri is considered a nomen dubium, Stephanopis aheneus is a junior synonym of Epicadus tuberculatus, Stephanopis quimiliensis is transferred to Ulocymus and Stephanopis stelloides is transferred to Epicadus, being Epicadus stelloides the senior synonym of Stephanopis salobrensis, Stephanopis trilobata and Epicadus caudatus.

Published: November 2021

This paper presents results of the examination of subject representation in the most recently created library metadata records. The bibliographic records were collected from the WorldCat global database. The records were created in 2020 according to the latest version of Resource Description and Access (RDA) and MARC 21Format for Bibliographic Data. A purposive sample of the records with the widest reach—as expressed in the highest number of holdings and the highest level of editing made by multiple institutions—was selected for in-depth content analysis. The level and patterns of application were analyzed for all subject representation data elements (record fields and subfields), specifically for those that were Linked-Data-enabling. The study examined the level and patterns of application of subject controlled vocabularies. Co-occurrences between various subject representation data elements and between subject controlled vocabularies within the records were explored.

Círculos matemáticos: uma experiência com alunos ingressantes no ensino superior no contexto da pandemia Covid-19
Authors: Capelato Erika
Published: November 2021

Os círculos matemáticos são tradicionais em Moscou há mais de cem anos. Eles não formam um conjunto de aulas para uma disciplina, mas fomentam o encontro de alunos com professores e monitores para estudar matemática em grupos. Inspirados em seu funcionamento realizamos, junto aos alunos ingressantes do curso de Ciências Econômicas de uma universidade pública do estado de São Paulo, o projeto de ensino intitulado “círculos matemáticos da economia”. O objetivo do projeto é contribuir com a melhoria da aprendizagem dos alunos que chegam à universidade com diferentes níveis de proficiência em matemática. Assim, este texto descreve e analisa a experiência da realização deste projeto no contexto da pandemia Covid-19. Para tal, lançamos mão de atividades digitais dirigidas aos participantes e das reflexões trazidas pela narrativa do monitor do projeto, através de uma produção escrita. Do ponto de vista metodológico, a discussão realizada a partir das respostas dos alunos em atividades digitais tem natureza quantitativa e mostram dados como o engajamento dos estudantes no projeto e suas percepções com respeito às atividades remotas. Já a discussão realizada em relação à narrativa tem natureza qualitativa e fundamenta-se em uma análise interpretativa, a qual nos leva a conclusão de que o convívio escolar, ainda que digital, é o ponto de partida para a construção da aprendizagem.

Dewey e a experiência estética: uma contribuição ao Ensino de Arte
Authors: Silva Tatiane , Cunha Marcus Vinicius
Published: November 2021

O objetivo deste artigo é oferecer contribuições ao ensino de arte por meio da teoria estética de John Dewey, realizando um experimento de pensamento – narrativa que emprega técnicas da literatura ficcional – que se efetua na forma de um drama – recurso didático que leva o aprendiz a um cenário fictício no qual se desenrola uma ação educativa. A primeira seção apresenta a teoria deweyana, enfatizando os conceitos de experiência, situação problemática e reflexão. A segunda seção apresenta um drama em que uma professora de educação infantil reflete sobre as suas experiências com a arte e busca solução para um problema: considerando que suas próprias experiências artísticas sempre foram negativas, como ensinar arte para seus alunos? O artigo põe a professora dentro de um experimento de pensamento, no qual ela conhece as teses de Dewey e obtém resposta para seu problema. A conclusão do artigo sugere que os professores de arte se sintam motivados a ter experiência semelhante à da professora.

Published: November 2021

O presente artigo reflete sobre as experiências de vida tidas na pandemia do Covid-19, em especial, as das crianças e dos adolescentes. Observamos, no âmbito da pandemia, as manifestações artísticas suscitadas e as vulnerabilidades sociais agravadas presentes na infância e na adolescência. Buscamos compreender essas experiências, a fim de pensar sobre o Ensino de Artes Visuais, especificadamente, os seus conteúdos curriculares, pensando no contexto de diferentes infâncias e juventudes adolescentes. Em segundo momento, discorremos sobre o Ensino de Artes Visuais diante da pandemia, com apoio na perspectiva de Dewey (2011), em especial, no seu capítulo intitulado ‘A organização progressiva das matérias e conteúdos curriculares’. Utilizamos como metodologia a revisão bibliográfica de livros, capítulos de livros, artigos e sites eletrônicos e consultas em plataformas virtuais de Artes Visuais. Concluímos que as visualidades da pandemia atuam como pedagogias culturais e que o Ensino de Artes Visuais pode abarcar a experiência de vida dos estudantes, a partir de conteúdos que proponham a reflexão sobre o momento contemporâneo.

Authors: Fonseca Annelise Nani da
Published: November 2021

Este artigo objetiva analisar a Experiência Estética de John Dewey (1859-1952) como um vetor para o processo criativo. Para isso, investiga junto a teoria deweyana caminhos por meio da gestalt-terapia para demonstrar isso. Seu objetivo consiste em ressaltar o seu papel fundamental para instigar a formação de linguagem autoral. Para tanto, o artigo apresentará autores para pensar a Experiência Estética atrelada a conceitos como: a Imaginação Simbólica com Gilbert Durand (1993), o conceito de awareness e ajustamento criativo com Jorge Ponciano (2011,1985). A pesquisa infere que a experiência estética é basilar para o processo criativo sendo um importante vetor para a awareness, e construção de linguagem autoral. Além disso, destaca que a experiência estética pode ser estimulada à distância, no contexto do Ensino Remoto Emergencial tendo um importante papel na participação dos alunos.

Alinhavadas é uma experiência poética na qual convido amigas/os, estudantes e/ou interessadas/os para costurar saias por meio da auto modelagem, utilizando somente o ponto alinhavo. Em 2019, costurei com pequenos grupos, conversando sobre os possíveis sentidos e visualidades que poderíamos construir: o que o uso deste artefato têxtil diz de nosso momento histórico-cultural? O que posso aprender e criar com as narrativas de outras pessoas sobre o uso de saias? O que podemos aprender destas memórias que deixam roupas como legados? Diante das ações de enfrentamento a pandemia COVID19 o alinhavo da saia se tornou um pretexto para a geração de encontros virtuais e/ou individuais. Alinhavadas é parte da pesquisa a/r/tográfica Narrativas Têxteis e Docência Artista, desenvolvida no campo da Educação da Cultura Visual, sob aportes de John Dewey (2010).

O presente artigo é um relato de experiência sobre as potencialidades do Minuto Lumière, um recurso audiovisual inspirado nas produções cinematográficas geminais dos Irmãos Lumière, como instrumento de avaliação da disciplina “Evolução”, de um curso de Licenciatura em Ciências Biológicas, cuja a oferta ocorreu remotamente em virtude da pandemia de COVID-19. Os alunos da disciplina, após orientações técnico-conceituais sobre o dispositivo, produziram e socializaram seus Minuto Lumière com o tema de Evolução Humana, que constituiu uma das avaliações da disciplina e apresentaram a visão daqueles conhecimentos científicos a partir da perspectiva dos alunos, constituindo uma instrumento viável e multinível para aprendizagens em biologia evolutiva.
Matisse, "The Moroccans": seeing For Yourself
Authors: Ellmann Barbara
Published: November 2021

A New York painter and freelance teaching artist describes an experience visiting Matisse’s painting “The Moroccans” at the Museum of Modern Art with a group of young people and their families. She describes her aesthetic education methods which include encouraging museum visitors to engage deeply with works of art by noticing, asking questions, and participating in group discussion. When the visitors’ conclusions about “The Moroccans” turn out to be at odds with the museum’s wall text, they question what they should believe—their own eyes or the museum’s official interpretation of this abstract work. Connecting this experience to John Dewey’s writing about the purpose of art and the power of the perceiver to activate an art object, the author reflects on the role of museums and the sometimes conflicting priorities of public engagement and scholarly authority.

Published: November 2021

Selon les modèles de contagion sociale, les adolescents fréquentant des pairs ayant décroché dans leur réseau seraient plus à risque de quitter l’école avant l’obtention d’un diplôme. Cette étude se penche sur ce phénomène en considérant l’ensemble des pairs significatifs (amis, partenaires amoureux, fratrie) pouvant influencer la décision de décrocher. Les analyses portent sur un échantillon d’adolescents (N = 545) issus d’écoles secondaires québécoises de milieux défavorisés où les jeunes à risque de décrochage sont surreprésentés. Tel qu’attendu, les adolescents dont le réseau de pairs comporte des pairs ayant décroché récemment sont plus à risque de décrocher, surtout lorsque plus d’un type de pair significatif a décroché.

Il s’agit d’éclairer comment ces thèses ont contribué à poser des cadres structurants pour la didactique de l’histoire, notamment des références théoriques, mais aussi de montrer la place des cheminements et des choix individuels dans la construction d’un espace scientifique.
La fiesta de los monstruos en La Virgen Cabeza y Yanara de Gabriela Cabezón Cámara
Authors: Scarcella Daniel , Torrano Andrea
Published: November 2021

Este artículo se propone indagar sobre la fiesta del monstruo en la literatura argentina contemporánea, particularmente en dos textos de Gabriela Cabezón Cámara: La Virgen Cabeza (2009) y Yanara (2018-2019). Nos interesan especialmente estos escritos porque encontramos en ellos una forma de la monstruosidad como forma de vida en común. La monstruosidad remite a los sujetos precarizados y cotidianos que encarnan un potencial de lucha y resistencia. Estos monstruos habitan en zonas urbanas también precarizadas, que pueden considerarse como un espacio de captura, pero que también permiten generar formas de auto-organización. La vida en común se refiere a lo barroso, la autogestión y la fiesta. Lo barroso aparece como una materialidad asociada con lo bajo y lo popular, y, al mismo tiempo, como un elemento aglutinante posibilitador de la unión de cuerpos y de modos de generar lazos sociales, culturales y afectivos. La fiesta se presenta como transgresión a los límites establecidos, a través del placer sexual, la comida, la celebración, la resistencia y lucha. La fiesta de los monstruos es la expansión de la vida en común y la posibilidad de crear una comunidad alternativa.
The case of Italy: Between tradition and Modernity
Authors: Ferrarotti Franco
Published: November 2021

If it were possible, just for an instant, to forget the sufferings and worries of the everyday, if, in other words, it were possible to distance ourselves and somehow see ourselves from outside, I think we should have to agree with Goethe’s confession: «I have the great advantage of being born in an age where the great events of the world were on the order of the day, so that I have been an eyewitness of the Seven Years War, of the separation of America from England, and later of the French Revolution, and ultimately of the whole Napoleonic period up to the hero’s fall and events that followed it». Maybe we can say the same of our times, with greater justification. We live in a remarkable era.
Rotational dynamics in motor cortex are consistent with a feedback controller
Authors: Kalidindi Hari Teja , Cross Kevin P , Lillicrap Timothy P , Omrani Mohsen , Falotico Egidio , Sabes Philip N , Scott Stephen H
Published: November 2021

Recent studies have identified rotational dynamics in motor cortex (MC), which many assume arise from intrinsic connections in MC. However, behavioral and neurophysiological studies suggest that MC behaves like a feedback controller where continuous sensory feedback and interactions with other brain areas contribute substantially to MC processing. We investigated these apparently conflicting theories by building recurrent neural networks that controlled a model arm and received sensory feedback from the limb. Networks were trained to counteract perturbations to the limb and to reach toward spatial targets. Network activities and sensory feedback signals to the network exhibited rotational structure even when the recurrent connections were removed. Furthermore, neural recordings in monkeys performing similar tasks also exhibited rotational structure not only in MC but also in somatosensory cortex. Our results argue that rotational structure may also reflect dynamics throughout the voluntary motor system involved in online control of motor actions.
Heavy metal pollution characteristics and health risk assessment of dust fall related to industrial activities in desert steppes
Authors: Xu Zhe , Mi Wenbao , Mi Nan , Fan Xingang , Tian Ying , Zhou Yao , Zhao Ya-nan
Published: November 2021

China’s desert steppe is the transition zone between the grasslands in central China and the arid desert. Ecological security in this region has long been a subject of debate, both in the local and academic communities. Heavy metals and other pollutants are readily released during industrial production, combustion, and transportation, aggravating the vulnerability of the desert steppes. To understand the impact of industrial activiteis on the heavy metal content of dust fall in the desert steppe, a total of 37 dust fall samples were collected over 90 days. An inductively-coupled plasma mass spectrometer (NexION 350X) was used to measure the concentration of heavy metals Cu, Cd, Cr, Pb, Mn, Co, and Zn in the dust. Using comprehensive pollution index and multivariate statistical analysis methods, we explored the characteristics and sources of heavy metal pollution. We also quantitatively assessed the carcinogenic risks of heavy metals resulting from dust reduction with the help of health risk assessment models. The heavy metals’ comprehensive pollution index values in the study area’s dust fall were ranked as follows: Zn > Cd > Pb > Mn > Cu > Co > Cr. Among these, Zn, Cd, and Pb were significant pollution factors in the study area, and were affected by industrial production and transportation. The high pollution index was concentrated in the north of the research industrial park and on both sides of a highway. The seven heavy metals’ total non-carcinogenic risk index (HI) values were ranked as follows: Mn > Co > Pb > Zn > Cr > Cu > Cd (only the HI of Mn was greater than one). Excluding Mn, the non-carcinogenic and carcinogenic risk index values of the other six heavy metals were within acceptable ranges. Previous studies have also shown that industrial transportation and production have had a significant impact on the heavy metal content of dust fall in the desert steppe.
Relationship between higher education teachers’ affect and their psychological adjustment to online teaching during the COVID-19 pandemic: an application of latent profile analysis
Authors: Zou Weixing , Ding Xiangmei , Xie Lingping , Wang Hongli
Published: November 2021

Background

The COVID-19 outbreak has forced teachers to transition to online teaching, requiring them to adapt their courses and pedagogical methods to an online format rapidly without relevant training. This has presented a formidable challenge to higher education teachers. The present study uses a person-centered approach to identify heterogeneity among higher education teachers’ affective experiences and the relationship between this heterogeneity and their psychological adjustment to online teaching.

Methods

In total, 2,104 teachers in higher education institutions in Southern China were surveyed using the Positive and Negative Affect Schedule and the Psychological Adjustment to Online Teaching Scale (a measure developed for this study) between March 25 and March 31, 2020. The collected data were analyzed using latent profile analysis.

Results

Based on their affective experiences during online teaching immediately after the COVID-19 outbreak, higher education teachers were divided into three latent classes: the common, ambivalent, and positive types. Among them, the positive type accounted for the largest proportion (44.85%), while the ambivalent type accounted for the smallest proportion (23.93%). The rest was the common type, which accounted for 31.15%. Significant differences in psychological adjustment to online teaching were found between the three latent classes. Regarding positive psychological adjustment, teachers belonging to the ambivalent type had significantly lower scores than those belonging to the other two types. Further, the common type had a significantly lower score than the positive type. Regarding negative psychological adjustment, the ambivalent type had a significantly higher score than the other two types, and the common type had a significantly higher score than the positive type.

Conclusion

Based on a novel person-centered perspective, this study revealed the differences and complexity in higher education teachers’ affective experiences of online teaching immediately after the COVID-19 outbreak. The three different types of affective experiences (common, ambivalent, and positive) had a significant influence on psychological adjustment, with teachers belonging to the ambivalent type showing the worst psychological adjustment. This study provides a new perspective for the discussion of the relationship between teachers’ affective experiences and their psychological adjustment to online teaching.
Integrative analysis of Iso-Seq and RNA-seq data reveals transcriptome complexity and differentially expressed transcripts in sheep tail fat
Authors: Yuan Zehu , Ge Ling , Sun Jingyi , Zhang Weibo , Wang Shanhe , Cao Xiukai , Sun Wei
Published: November 2021

Background

Nowadays, both customers and producers prefer thin-tailed fat sheep. To effectively breed for this phenotype, it is important to identify candidate genes and uncover the genetic mechanism related to tail fat deposition in sheep. Accumulating evidence suggesting that post-transcriptional modification events of precursor-messenger RNA (pre-mRNA), including alternative splicing (AS) and alternative polyadenylation (APA), may regulate tail fat deposition in sheep. Differentially expressed transcripts (DETs) analysis is a way to identify candidate genes related to tail fat deposition. However, due to the technological limitation, post-transcriptional modification events in the tail fat of sheep and DETs between thin-tailed and fat-tailed sheep remains unclear.

Methods

In the present study, we applied pooled PacBio isoform sequencing (Iso-Seq) to generate transcriptomic data of tail fat tissue from six sheep (three thin-tailed sheep and three fat-tailed sheep). By comparing with reference genome, potential gene loci and novel transcripts were identified. Post-transcriptional modification events, including AS and APA, and lncRNA in sheep tail fat were uncovered using pooled Iso-Seq data. Combining Iso-Seq data with six RNA-sequencing (RNA-Seq) data, DETs between thin- and fat-tailed sheep were identified. Protein protein interaction (PPI) network, Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analyses were implemented to investigate the potential functions of DETs.

Results

In the present study, we revealed the transcriptomic complexity of the tail fat of sheep, result in 9,001 potential novel gene loci, 17,834 AS events, 5,791 APA events, and 3,764 lncRNAs. Combining Iso-Seq data with RNA-Seq data, we identified hundreds of DETs between thin- and fat-tailed sheep. Among them, 21 differentially expressed lncRNAs, such as ENSOART00020036299, ENSOART00020033641, ENSOART00020024562, ENSOART00020003848 and 9.53.1 may regulate tail fat deposition. Many novel transcripts were identified as DETs, including 15.527.13 (DGAT2), 13.624.23 (ACSS2), 11.689.28 (ACLY), 11.689.18 (ACLY), 11.689.14 (ACLY), 11.660.12 (ACLY), 22.289.6 (SCD), 22.289.3 (SCD) and 22.289.14 (SCD). Most of the identified DETs have been enriched in GO and KEGG pathways related to extracellular matrix (ECM). Our result revealed the transcriptome complexity and identified many candidate transcripts in tail fat, which could enhance the understanding of molecular mechanisms behind tail fat deposition.

Aim: Stability Study of Mucoadhesive Microsphere Containing Nateglinide by Using Biodegradable Polymer Chitosan

Study Design: The investigation of the stability of Nateglindine containing mucoadhesive microsphere by using chitosan was carried out.

Methodology: The present study was performed to test the stability of microspheres formulation. The promising formulations were selected for in-vitro stability studies. Formulations were stored in screw-capped, amber color small glass bottles at 4±1°C, 27±2°C, and 42 ± 2°C for 45 days. After 0, 15, 30, and 45 days they were evaluated for the following parameters like particle size, and percent residual drug content.

Results: The particle size of the microspheres was found to increase slightly at 4±1°C from initial to 45 days which might be due to the agglomeration of particles. While at a higher temperature that is 27±2°C, an increased in particle size was observed to more as compared to particle stored at 4±1°C could be due to agglomeration of microspheres more at a higher temperature. As the period passed, the concentration of the drug in the formulation was decreased with time but at the highest (42±2°C) temperature degradation rate was maximum.

Conclusions: The stability study of microsphere containing Nateglinide concludes that the formulation CM-4326F was the best formulation in drug stability studies. As the period passed, the concentration of the drug in the formulation was decreased with time but at the highest (42±2°C) temperature degradation rate was maximum. Hence it was concluded that temperature 4±1°C or 27±2°C are suitable for storage of formulation because little changed was found in particle size and residual drug content.

Background: The Niger Delta region of Nigeria is popularly known for its huge deposit of crude oil which during explorative activities has led to the pollution of soil and water bodies of nearby coastal regions such as Ogoni.

Aim: This study aimed to assess the bacterial diversity of the GIT of induvial living in hydrocarbon-impacted Ogoni communities.

Methods: Eighty (80) stool samples were collected as case subjects (people living in hydrocarbon-impacted Ogoni communities). Twenty (20) subjects were collected as control samples (people living in Ikenga Ogidi in Idemili North LGAs of Anambra State Nigeria which is a non-hydrocarbon- impacted region). These samples were cultured and analyzed for genomic studies using standard procedures, antimicrobial profiling was done using standard antibiotic disc, the resistant and virulent genes were also assessed using the thermal cycler PCR techniques.

Results: The phylogenic analyses of the 16S rRNA for case and control subjects review the isolates within the Escherichia coli, Klebsiella pneumoniae, Providencia, Morganella, Proteus, and Lysinibacibacillus mecroides, Commamonas thiooxydans, Proteus mirabilis, Escherichia coli, Klebsiella pneumoniae, and Enterobacter asburiae respectively. Antibiotic resistance profiling reviewed resistance to the following antibiotic AZN (43%), CIP (11%), EPT (20%), CT (47%), IPM (11%), CN (40%), NOR (11%), CTX (94%), and AZN (0%), CIP (40%), EPT (20%), CT (80%), IPM10%, CN20%, NOR (70%,) CTX (70%) for case and control subjects respectively. The prevalence of resistance genes were CTX (56%), SHV (28%), TEM (28%) for case subjects. The virulence genes, Stx1 had (16%), Adhesin (40%), Stx (10%) and Adhesin (20%) for case and control respectively. No resistance genes were found in the control while more virulence genes were found in the case than the control subjects.

Conclusion: These finding revealed that individual living in hydrocarbon impacted Ogoni communities harbor resistance genes that could pose great risk to their health.

Multiscale Stochastic Stress Analysis of Unidirectional FRP Considering Random Fiber Location Variation by an Improved Successive Local Approximation
Authors: Sakata Sei-ichiro , Hirata Masayuki
Published: November 2021

Herein, a multiscale stochastic stress analysis of a unidirectional fiber reinforced composite material considering random fiber location variation in microscale is discussed. Since a microscopic quantity has an influence on the apparent material properties of heterogeneous materials, and a microscopic geometrical feature has a significant influence on microscopic stresses in composites. When microscopic randomness or uncertainty is observed, an apparent material property such as strength will become a random response, and therefore the uncertainty propagation through the different scales should be investigated for more reliable design of composite structures. For this problem, the Monte Carlo simulation‐based approach will be effective but expensive because many fibers should be considered for more accurate analysis, and the successive local approximation‐based approach has been proposed. However, accuracy of this approach depends on the local surrogate of the stresses for random variables, and an improved approach is proposed herein. In the proposed approach, a numerical condition for constructing a lower order surrogate is adjusted to minimize the estimation error to a reference solution obtained from a higher‐order surrogate. Herein, the problem settings and outline of the methods are introduced. Then, numerical results are provided for discussing effectiveness of the proposed approach.
