Published: July 2022

Este artigo fundamenta-se na observação de como o discurso constrói subjetivações para os sujeitos envolvidos na aprendizagem da língua inglesa. Temos como objetivo esboçar alguns apontamentos sobre as inscrições discursivas enunciadas no teachgram BBC Learning English em relação ao conceito de motivação. Nessa perspectiva, partiremos do aporte teórico e metodológico da Análise do Discurso, segundo a visão de Michel Pêcheux (2010). Assim sendo, os posts do referido perfil voltados para a temática da motivação são enunciados, ou seja, produções da linguagem que englobam sujeitos, instâncias oficiais de produção, sendo possíveis a partir das práticas sociais. Podemos observar que o conceito de motivação do teachgram BBC Learning English é permeado por diversas formações discursivas. Percebe-se a “formação discursiva da sociedade pós-moderna”, bem como a “formação discursiva de sobrevivência dos excluídos em uma sociedade capitalista pós-moderna”.

COVID-19 pandemic is the major outbreak that has exterminated many lives for past years and still not subsided completely. A number of vaccinations are in trials to eradicate the COVID-19 virus. This study deals with the challenges posed by anti- inflammatory drugs in the treatment of COVID-19.NSAID'S can mask early symptoms such as fever,myalgia in COVID-19 infected patients and can be used as adjunct therapy in severe COVID-19 treatment as they have anti-viral and anti-inflammatory properties. The risk of infection was found to be declined in the patients who had prior aspirin exposure. Indomethacin must be used with caution as it exhibits coronary vasoconstriction effects in patients. Anakinra even at higher doses resulted quite safe in COVID-19, confirming its potential role in selected conditions like immune compromised patients with superinfection, contraindications to other anti-inflammatory drugs. Early management with tocilizumab prevents cytokine strom and mortality. Patients who received Hydroxychloroquine with azithromycin combination had frequent cardiac arrest. No reasons to pause NSAIDs and no evidence of mortality rate dissimilarity between ibuprofen and paracetamol in COVID-19. still paracetamol remains first line. WHO guidelines recommend to avoid corticosteroids in COVID-19 management.

Gender equality in political life in Indonesia
Authors: Ardiansya Ariyanto , Sulaiman Sunarwan , Nasrullah Nasrullah , Maskawati Maskawati
Published: July 2022

In Indonesia, the issue of gender equality has lately become an endless issue and is still striving to continue to be championed both at the executive and legislative levels. The issue of gender equality includes substantive understanding of the gender perspective policy itself. Therefore, the gender movement then became mainstream in developing countries including Indonesia. In the process of democratization, the issue of greater women's political participation, representation and the issue of accountability is an absolute requirement for the realization of a more meaningful democracy in Indonesia. A meaningful democracy is democracy that pays attention to and fights for the interests of the majority of Indonesia's population consisting of women. The idea that politics is not territory for women is an idea that has always been echoed for centuries, and it is indeed very effective to restrict women from entering this region. Public and private terminology that is closely related to the concept of gender, gender roles, and stereotypes, has created inequality and injustice between women and men. The most obvious result of such a political situation is the marginalization and exclusion of women from formal political life.

Published: July 2022

This study aims to provide the latest information regarding the accuracy of contrast and non-contrast 1.5 Tesla MRI in the diagnosis of lumbar Herniated Nucleus Pulposus (HNP) compared with surgical findings. We included studies with subjects diagnosed with lumbar HNP due to degenerative processes, preoperative 1.5 Tesla contrast, and non-contrast MRI and described the number of findings of MRI diagnostic tests (index test) on the actual conditions found during surgery (reference standard). We searched literature from 5 databases: ProQuest, Pubmed, Cochrane Library, Biomed Central, and ScienceDirect. The sensitivity and specificity of contrast and non-contrast 1.5 Tesla MRI ranged between 64-95% and 55-100% (95% CI) with the area under the curve above the threshold on the ROC curve. Two studies compared the accuracy of MRI and Computed Tomography (CT) myelography with a wider ROC curve on CT myelography than on MRI. The ROC curve which has a wide area under the curve above the threshold depicts the relationship between sensitivity and specificity, shows that contrast non-contrast 1.5 Tesla MRI has a good accuracy in HNP diagnostic.

Coexistence of Large-Scale Mining with Artisanal and Small-Scale Mining—A Guide for Geologists
Authors: Holley Elizabeth A. , Rodriguez Oscar Felipe , Redwood Stewart D. , Smith Nicole M.
Published: July 2022

Editor’s note: The aim of the Geology and Mining series is to introduce early career professionals and students to various aspects of mineral exploration, development, and mining in order to share the experiences and insight of each author on the myriad of topics involved with the mineral industry and the ways in which geoscientists contribute to each.

Artisanal and small-scale mining (ASM) takes place in approximately 80 countries, and it is widespread in parts of Central and South America, Africa, Asia, and Oceania. Estimates range from 40 to 100 million ASM miners operating worldwide, and ASM generates a significant share of global production for commodities such as gold, tantalum, tin, gemstones, and diamonds. Geologists may encounter ASM activity when exploring new areas or when ASM miners move into existing exploration projects or the vicinity of large-scale mines. These interactions can be contentious, leading to conflicts that force project delays or abandonment. Alternatively, both groups can collaborate to generate mutual benefits, enabling mining companies to gain social license to operate and at the same time manage the environmental impacts of ASM, while the ASM miners maintain culturally and economically important livelihoods. Technical and social factors can help to predict the potential for coexistence or conflict with ASM operators, including the geology of the deposit type, the mining method, and the economic, legal, historical, and cultural context of a project. We present a series of case studies on ASM in Latin America, highlighting five coexistence models that have been previously implemented between mining companies and ASM operators. Our intent is to raise awareness of ASM, so that geologists can consciously consider its impacts on early exploration and subsequent decision-making. Secondly, we aim to encourage broader discussion of the role of ASM in mineral production and sustainable development.
Music in Constructing Finnish American Identities in the Immigrant Novel by Martin Koskela
Authors: Kushnir Roman
Published: July 2022

In the immigrant novel Welcome to Shadow Lake (1996) by the Finnish American author Martin Koskela, music is portrayed as a notable component of the ethnic heritage of Finnish American immigrants and their descendants in the US in the 1930s. This article analyzes the roles of music in characters’ identity formation with the help of the concept of transculturation, as developed by Mary Louise Pratt, and the theories of music in constructing and negotiating identity developed by Mark Slobin, Martin Stokes, Simon Frith, Georgina Born, and Ulrik Volgsten. Characters use their musical activities to maintain their Finnishness in the new country, but their Old Country music changes by acquiring new meanings and eventually by incorporating new traits of US and Finnish cultures. The discussion focuses on two aspects of music in Koskela's novel. First, live music and related activities such as dances, performed by ethnic Finnish bands as well as visiting musicians, function as shared markers of Finnish American ethnicity. The characters help build and maintain an ethnic community, but at the same time make their “little Finland” an integrated part of the United States. Second, recorded and radio broadcast music provides the characters with both a gateway to America and new symbols of Finnishness, thus enabling different generations of Finnish Americans to negotiate their identities in relation to the past and present, their Old Country heritage, and their sense of American identity. On the whole, the characters’ music reflects identities that are transcultural, both Finnish and American.

At the same time, it provides a basis for the semantic representation and editing of the femoral model in the subsequent processes.
Mesenchymal Stem Cell Exosomes as Nanotherapeutic Agents for Neurodegenerative Diseases
Authors: Su Rui
Published: July 2022

Neurodegenerative diseases are systemic diseases with high heterogeneity and complicated etiology dependent on proper interneuronal communication, resulting in severe syndromes including cognitive impairment and dementia. The blood-brain barrier (BBB) remains Central nervous system (CNS) therapeutic delivery, a significant challenge without effective vivo therapeutic methods in clinical practice. Mesenchymal stem cells (MSC) with multi-directional differentiation potential have the characteristics of low immunogenicity, strong proliferation ability, immune regulation, and multi-directional differentiation potential. The repair effects have been identified mediated by transplanted MSCs paracrine factors, including exosomes and nanometer-sized cell communication mediators, to reduce tissue injury and enhance repair, growth, and regeneration. MSC-derived exosomes have become an attractive vehicle by passing through the blood-brain barrier (BBB), delivering therapeutic agents targeting the brain for treating autoimmune and neurodegenerative diseases. Safeties, convenience, and the effectiveness of MSC-derived exosomes have been demonstrated mainly through mechanistic clinical and preclinical evidence of potential nanotherapeutic agents for further prevalent use. Thus, we want to investigate the clinical applications of MSC-derived exosomes to reveal their regenerative treatment capacity from direct and indirect neuron repairment effect, reduced neuroinflammation, and nanotherapeutic agent advantage. This paper discusses the potential and practicality of using this novel cell-free entity of mesenchymal stem cell derivatives such as exosomes in vivo administration as a therapeutic modality for treating degenerative disease and pathologies and innovation and emerging trends in the field.

Authors: Qin Haoyuan
Published: July 2022

Aspects around cardiovascular disease (CVD), especially its predisposing factors, have been studied for a long period. Recent studies have largely concentrated on coffee intake by elderly individuals with type 2 diabetes and its association with CVDs. Others have looked at the potential of coffee and tea in preventing CVD. The association between intake of caffeinated coffee with heart valve disease among the elderly has been another area of interest. However, there is still a gap in research in this area, explaining why this review was conducted to explore the effects of caffeinated coffee on human cardiovascular function as well as the association between coffee consumption and the blood pressure level. The review concludes that Caffeinated coffee consumption is associated with a lower risk of CVD. However, the association between caffeinated coffee intake and blood pressure needs further study.

Analysis of GSH1-GSH3 Genes by Comprehensive Use of Bioinformatics Method in Tomato
Authors: Pang Yulong
Published: July 2022

GSH is a ubiquitous gene family in animals and plants, which plays a key regulatory role in plant growth, development and stress response. In this study, three GSH genes are identified in the Phytozome database, and bioinformatics analysis of physicochemical properties, structural domains, promoter cis-acting elements and phosphorylation sites is performed. The results show that the numbers of introns and exons of tomato GSH1-GSH3 are quite different. Promoters cis-acting elements are analyzed in GSH gene promoters, which account for a large proportion of light-responsive, hormone-responsive and protein synthesis elements. Transcription factors based on different tissues group data analysis reveal that the expression of GSH genes is different in different tissue development processes. The highest expression sites of GSH1-GSH3 are in 1-cm fruit, GSH2 currant tomato fruit and roots five days after veraison. According to physicochemical properties, transmembrane structure and signal peptide, the study finds that GSH proteins are all hydrophilic proteins and do not have a transmembrane structure and signal peptides. Based on the data analysis of protein phosphorylation sites and glycosylation sites, it is found that the number of the two sites differ significantly between GSH proteins. By means of prediction of secondary and tertiary structures in proteins, it finds that the three GSH proteins have four secondary structures: α-helix, extended chain, β-turn and random coil, but the proportions are different, and the tertiary structures of the three are quite different. Based on the analysis of protein phylogenetic tree, it is believed that tomato and potato are closely related. According to the protein interaction network, it points out that there is a strong link between GSH1 and GSH3. Through the analysis of tomato GSH family system, this study is expected to provide a theoretical basis for further research on the biological function of GSH gene.

Authors: Jin Winston , Farrell Sarah , Habib Eva , Sandhu Ash , Bone Jeffrey N. , Schaeffer Emily , Mulpuri Kishore
Published: July 2022

Purpose:

Slipped capital femoral epiphysis is commonly treated with in situ pinning (ISP) and more recently the modified Dunn procedure (MDP). This study retrospectively examines the preoperative risk factors and postoperative complications of patients treated with either ISP or MDP over a 12-year period.

Methods:

A single-center, retrospective review was conducted on patients diagnosed and surgically treated with slipped capital femoral epiphysis from 2004 to 2016. Patients must have had preoperative imaging and a minimum of 6 months of clinical follow-up. Six preoperative demographic data (age, sex, intensity of symptoms, stability, trauma, and severity of slip), surgical details, and treatment outcomes were collected. Descriptive statistics were used to identify pertinent preoperative risk factors and postoperative complications in each treatment group.

Results:

A total of 129 hips in 98 patients were treated (118 with ISP and 11 with MDP). Complications developed in 12 hips. Six hips developed osteonecrosis, two hips developed osteonecrosis and chondrolysis, two hips developed osteonecrosis and slip progression, and two hips developed slip progression only. Four of the 11 hips (36.4%) treated with MDP developed complications; 8 of the 118 hips (6.8%) treated with ISP developed complications.

Discussion:

Complications developed in 9.3% of hips treated with ISP or MDP, with a higher rate of complications observed in the MDP group compared with the ISP group. This study is limited by the small sample size of the cohort and the disproportion in the number of cases in each treatment group. A multicenter study with larger sample sizes will be required to confirm these findings.

Introduction:

Studies comparing the cost of in-person and virtual care are lacking. The goal of this study was threefold (1) to compare the cost of telemedicine visits with in-person clinic visits after common shoulder surgeries, (2) to measure the safety, and (3) to evaluate patient experience with telemedicine visits.

Methods:

The In-Person Visit cohort (N = 25) and the telemedicine cohort (Virtual Visit cohort, N = 24) were selected from patients undergoing routine follow-up of common shoulder procedures. Time-driven activity-based costing was used to determine costs associated with each episode of care. Patient complications, satisfaction, convenience, and technical difficulties associated with telehealth were recorded.

Results:

The average Virtual Visit was 54.1% less costly and 87.8% shorter than the In-Person Visit ($49 versus $107 per patient, 8.6 versus 70.1 minutes per patient, P < 0.01, respectively). One complication was missed in the Virtual Visit cohort, later captured by an in-person visit. All patients in the Virtual Visit cohort reported that the virtual visit was safe and convenient and showed high levels of satisfaction.

Discussion:

Virtual visits for postoperative care of patients undergoing shoulder surgery are associated with decreased costs and high ratings of convenience and satisfaction. Postoperative complications may be more challenging to diagnose virtually.

Pain and damage to tissue structure is frequently observed after surgical procedures. Management of postoperative pain has always been remained a challenge to surgeons because of its detrimental effect on patient’s satisfaction, early mobilization and regaining of functionality. Objective: To compare the analgesic efficacy of diclofenac suppository with injection tramadol 100 mg for postoperative pain relief after abdominal surgeries. Methods: This Randomized Double-Blind Controlled Trial was conducted upon a sample of 98 patients, aged 12 to 60 years and undergoing abdominal surgery (elective and emergency) divided into two groups (Group A: Diclofenac Suppositories 100 mg, and Group B: Injection Tramadol 100 mg), of 49 patients each. Visual Analogue Scale (VAS) was used for measuring the severity of pain at 0, 1, 6, 12, 18 and 24 hours, following surgeries. Results: The mean age of the sample stood at 31 (SD ± 03) years, with most of the sample comprising of males (72.45%). Postoperative pain was experienced by patients in both groups, with group A reporting less severe pain than group B but no statistical difference was found between the severity. Conclusion: After careful consideration, it may be concluded that both agents, namely Diclofenac Suppositories 100 mg, and Injection Tramadol 100 mg are efficacious at managing the postoperative pain hence both may be used interchangeably or in conjunction among patients undergoing abdominal surgeries.

Glaucoma is a primary cause of irreversible blindness worldwide, it kills the vision silently, having a financial burden on society regarding therapy expenses and loss of valuable hours of the day. Objective: To compare the choroidal filling time and grade the status and pattern of optic nerve head (ONH) perfusion by fundus fluorescein angiography (FFA) in glaucoma patients Methods: Patients with various types of glaucoma were enrolled and compared them with healthy volunteers with no history and findings of glaucoma. Perfusion status using FFA was studied and analyzed corresponding visual fields (VF) and optical coherence tomography (OCT) findings Results: There were 70 participants in the study, including 48 glaucoma patients and 22 healthy controls. Choroidal filling time (CFT) was 9-12, 13-17, 15-22, and 20-33 seconds in healthy individuals and patients with ocular hypertension (OH), primary open-angle glaucoma (POAG), and normal-tension glaucoma (NTG), respectively. In OH, inferonasal and inferotemporal hypofluorescence pattern of ONH perfusion was noted, whereas POAG showed an inferonasal, patchy, and undefined pattern of hypofluorescence. In contrast with the healthy volunteers that showed uniform fluorescence, patients with NTG showed inferonasal hypofluorescence. CFT was significantly delayed in NTG patients (p<0.05). We found a strong correlation between findings of FFA, OCT, and corresponding VF defects in glaucoma patients Conclusions: The choroidal filling time is prolonged in patients with various types of glaucoma, especially in cases of normal-tension glaucoma. FFA reveals perfusion defects in the form of areas of hypofluorescence and multiple characteristic optic nerve head perfusion patterns in cases of POAG, NTG, and OH.
The Influence of the Structural Features of Molecules on Spontaneous Polarization Value in Induced Ferroelectric Liquid Crystal Systems
Authors: Bezhanova L. S. , Atanesyan A. K.
Published: July 2022

The occurrence of the large value of spontaneous polarization is established in LC system whose composition`s molecular structure does not satisfy the obligatory conditions for the occurrence of spontaneous polarization that are imposed by theory on a molecular structure. The essential role of short range intermolecular forces in the process of ferroelectric phase transition in the studied LC systems is shown. It was found that for {CC}, {DD} and {AD} interactions the most beneficial molecules` packing in terms of energy is the antiparallel one . In the case of {AA} and {AC} interactions both parallel and are equally beneficial in terms of energy. The possibility of formation of molecular clusters–dimers is shown. It is concluded that these are stabilized, in particular, by dipole–dipole interaction of molecules. A dimer model for increasing the value of spontaneous polarization is proposed.

Authors: Luo Yibin
Published: July 2022

In 2017, the Ministry of Finance issued a new standard on financial instruments to achieve convergence with international accounting standards, in which the emergence of expected credit loss model has great significance and far-reaching impact on the development of enterprises in China. In this paper, the impact of expected credit loss model on the quality of corporate accounting information is studied by using Differences-in-Differences method. Using accounting conservatism as a proxy variable for accounting information quality, this paper finds that the expected credit loss model can improve the accounting conservatism of enterprises. The findings of this paper show that the expected credit loss model is effective in improving the quality of accounting information, thus justifying the feasibility and necessity of implementing the new financial instruments standard and providing a good empirical basis for deepening the reform of accounting standards in China in the future.

Owing to the unstable food system nowadays, it is urgent to establish a new food system that is robust enough, so we established the current food system scoring model based on 21 indicators at three levels: economy, environment, and food & nutrition. Then normalize the corresponding data of each indicator, and use DEA and entropy weight method(EWM) to calculate the weight to quantify the score of the food system. When strengthening the consideration of sustainability and equity, we use the grey correlation method to analyze the correlation coefficients between sustainability, equity and the main indicators, then get the optimized score. In addition, we introduced Holt's two-parameter exponential smoothing time series analysis model to predict the development trend of the score of the existing system and the enhancement system, and determine the time required for enhancement to produce a certain effect.
Study on Local finance and government debt scale
Authors: Wen Zhuoli
Published: July 2022

Based on the scholar’s research on the influencing factors of local government debt, this paper argues that the local government financial resources, degree of decentralization and local government investment enthusiasm in local finance are the significant factors that influence the form of local government debt. This paper also chooses the panel data of China’s 31 provinces (cities) except Hong Kong, Macao and Taiwan from 2010 to 2019, to analyze the influencing factors of local government debt scale and the relationship of local government debt scale in different regions and demonstrates the correctness of the hypothesis proposed in this paper. The analyze result shows that the local government financial resources significantly inhibit the growth of local government debt. The degree of local decentralization is an essential factor to enlarge the scale of local government debt. There is a significant positive correlation between the enthusiasm of local government investment and the scale of local government debt.
