Authors:   Tomsk State University of Control Systems and Radioelectronics (TUSUR), Ivanov A. A. , Komnatnov M. E. ,   Tomsk State University of Control Systems and Radioelectronics (TUSUR)
Published: September 2021

The paper presents a semi-analytical method for calculating the shielding effectiveness (SE) of an enclosure with an aperture filled with a dielectric or magnetic material. The method is based on a combination of quasi-static analysis of coplanar strip lines (CPS) and an analytical model of an enclosure equivalent circuit. A simulation of a CPS is reduced to solving a simple electrostatic problem and can be performed by any available numerical method. The SE calculation can be performed using any of the existing models of an enclosure equivalent circuit. In the range up to 1 GHz, a validation of the proposed method was carried out using a standardized enclosure 300×120×300 mm3 as an example. To show the capabilities of the method, the paper presents the results of SE for enclosures with a PVC ventilation grill and a glass in the aperture. Using this method in conjunction with a previously published analytical model, the SE calculations for the enclosure with a conducting plate were also performed. The results show that the proposed method has an acceptable accuracy, and the average value of the absolute error does not exceed 6.4 dB

Amphibole fractionation and its potential redox effect on arc crust: Evidence from the Kohistan arc cumulates
Authors: Zhang Jingbo , Wang Rui , Hong Jun
Published: September 2021

Arc magmas, a major contributor to continental crust growth, are thought to be more oxidized than mid-ocean ridge basalts as reflected by an enrichment in ferric iron relative to ferrous iron. But how arc magmas become oxidized is hotly debated. It is acknowledged that the fractionation of common Fe-rich phases (e.g., amphibole) may change the Fe valence of the derivative melt. Amphibole has Fe-rich compositions commonly found in arc systems. We present high-precision (±0.01%) Fe valence data of amphibole and cumulates from the Kohistan arc determined by Mössbauer spectroscopy and bulk cumulate Fe3+/ΣFe ratios by wet chemistry. We evaluate the Fe3+/ΣFe trend of Fe-rich amphibole during arc magma fractionation. Our results show that bulk Fe3+/ΣFe ratio of cumulates in mature island arc settings is mainly controlled by amphibole due to its abundance and decreases (from 0.4 to 0.2) with decreasing Mg# as Fe3+/ΣFe ratios decrease in amphibole (from 0.35 to 0.2). Our modeling suggests that amphibole fractionation from parental arc magmas to Fe3+/ΣFe above 0.2 may lead to an increase in Fe3+/ΣFe ratios of middle–late stage residual melts by 0.1–0.3, and the partitioning of ferrous Fe into amphibole increases with the evolution of arc magmas. Our findings highlight the importance of petrological processes in the magma that contribute to the production of fertile arc crust.

On the Q operator and the spectrum of the XXZ model at root of unity
Authors: Miao Yuan , Lamers Jules , Pasquier Vincent
Published: September 2021

The spin-\frac{1}{2}12
Heisenberg XXZ chain is a paradigmatic quantum integrable model.
Although it can be solved exactly via Bethe ansatz techniques, there are
still open issues regarding the spectrum at root of unity values of the
anisotropy. We construct Baxter’s Q operator at arbitrary anisotropy
from a two-parameter transfer matrix associated to a complex-spin
auxiliary space. A decomposition of this transfer matrix provides a
simple proof of the transfer matrix fusion and Wronskian relations. At
root of unity a truncation allows us to construct the Q operator
explicitly in terms of finite-dimensional matrices. From its
decomposition we derive truncated fusion and Wronskian relations as well
as an interpolation-type formula that has been conjectured previously.
We elucidate the Fabricius–McCoy (FM) strings and exponential
degeneracies in the spectrum of the six-vertex transfer matrix at root
of unity. Using a semicyclic auxiliary representation we give a
conjecture for creation and annihilation operators of FM strings for all
roots of unity. We connect our findings with the `string-charge duality’
in the thermodynamic limit, leading to a conjecture for the imaginary
part of the FM string centres with potential applications to
out-of-equilibrium physics.
Identifying the volatility of compliance risks for the pension custodian banks
Authors: Achkasova Svіtlana , Bezrodna Olena , Ohorodnia Yevheniia
Published: September 2021

The high probability of risk transfer from banks to their counterparties in the field of non-state pension provision (pension account owners, non-state pension funds, insurance companies, asset management companies, etc.) determines the relevance of this study. The paper aims to develop a toolkit for identifying the compliance risk volatility for pension custodian banks based on causal modeling.This toolkit contributes to: 1) tentative cognitive mapping of the causal relationship between the compliance risks of pension custodian banks in the field of financial monitoring and financial and reputational risks to assess their acceptability by stakeholders in non-state pension programs, and 2) impulse modeling. The created toolkit is based on the performance data provided by Ukrainian banks, as well as on the reports of the National Bank of Ukraine. Apparently, an increase in penalty rates by 0.1% would reduce the compliance risks for banks by 0.03%, and the number of violations in financial monitoring (specifically the improper assessment/reassessment of customer risks) by 0.01%. In turn, the compliance risk volatility inherent in custodian banks affects the variability of their reputational and financial risks. Thus, reducing the compliance risks by 0.1% would improve the reputation of banks and increase their regulatory capital by 0.01%.The study findings substantiate the use of the created toolkit to supplement the risk profile components for pension custodian banks, thereby demonstrating the potential volatility of their compliance risks and their consequences for banks and individual groups of their stakeholders. AcknowledgmentThe work is prepared and financed within the framework of the state budget research work No. 45/20202021 “Formation of a risk-oriented system of accumulative pension provision” (DR No. 0120U101508).

This is achieved by examining how China's green BRI agenda and infrastructure development projects were undertaken in different partner countries. By doing so, we sought to identify gaps and opportunities for pursuing green developments across and through the BRI. The findings from this study contribute to the overall debate and exploration of sustainable development of BRI.
Applicability of different textile materials in filtration process integrated with SBR for wastewater reuse in small settlements
Authors: Gunes Sinem , Ayol Azize
Published: September 2021

In recent years, research activities on water reuse applications have rapidly increased to manage natural water sources efficiently. Although these applications in centralized treatment systems can be effective, there are some drawbacks, including the economic factors for small settlements. In this study, a textile filtration unit with the integration of a sequencing batch reactor (SBR) was developed and different textile materials were used to enhance the treated effluent quality for reuse purposes. While the textile filtration unit alone could not effectively remove the pollutants, the removal efficiencies could not exceed 36% for COD and 50% for BOD5. However, SBR integration in to the filtration system improved the treated wastewater quality and COD and BOD5 reductions were obtained higher than 93%. Activated carbon coated cotton textile materials and activated carbon cloth, which was used for the first time for wastewater treatment, increased the treatment performance. In the filtration system, although the suspended solids were high in the SBR effluent, no clogging problem was observed even with higher operation times. This paper presents the research results on this textile filtration system, and experimental findings are discussed on the applicability of the system for small communities.

Inflammation, Oxidative Stress, Vascular Aging and Atherosclerotic
Ischemic Stroke
Authors: Koutsaliaris Ioannis K. , Moschonas Iraklis C. , Pechlivani Louisa M. , Tsouka Aikaterini N. , Tselepis Alexandros D.
Published: September 2021

Vascular aging is a crucial risk factor for atherosclerotic ischemic stroke. Vascular
aging is characterized by oxidative stress, endothelial dysfunction, inflammation, intimal
and media thickening, as well as the gradual development of arterial stiffness,
among other pathophysiological features. Regarding oxidative stress, increased concentration
of reactive oxygen and nitrogen species is linked to atherosclerotic ischemic stroke in
vascular aging. Additionally, oxidative stress is associated with an inflammatory response.
Inflammation is related to aging through the “inflammaging” theory, which is
characterized by decreased ability to cope with a variety of stressors, in combination with
an increased pro-inflammatory state. Vascular aging is correlated with changes in cerebral
arteries that are considered predictors of the risk for atherosclerotic ischemic stroke. The
aim of the present review is to present the role of oxidative stress and inflammation in
vascular aging, as well as their involvement in atherosclerotic ischemic stroke.
Accumulating Impact of Smoking and Co-morbidities on Severity and
Mortality of COVID-19 Infection: A Systematic Review and Meta-analysis
Authors: Kumar Rupesh , Rai Avdhesh Kumar , Phukan Mayur Mausoom , Hussain Anowar , Borah Debajit , Gogoi Bhaskarjyoti , Chakraborty Poulomi , Buragohain Alak Kumar
Published: September 2021

Background:

High prevalence, severity, and formidable morbidity have marked the recent emergence of the novel coronavirus disease (COVID-19) pandemic. The significant association with the pre-existing co-morbid conditions has increased the disease burden of this global health emergency, pushing the patients, healthcare workers and facilities to the verge of complete disruption.

Methods:

Meta-analysis of pooled data was undertaken to assess the cumulative risk assessment of multiple co-morbid conditions associated with severe COVID-19. PubMed, Scopus, and Google Scholar were searched from January 1st to June 27th 2020 to generate a well-ordered, analytical, and critical review. The exercise began with keying in requisite keywords, followed by inclusion and exclusion criteria, data extraction, and quality evaluation. The final statistical meta-analysis of the risk factors of critical/severe and non-critical COVID-19 infection was carried out on Microsoft Excel (Ver. 2013), MedCalc (Ver.19.3), and RevMan software (Ver.5.3).

Results:

We investigated 19 eligible studies, comprising 12037 COVID-19 disease patients, representing the People’s Republic of China (PRC), USA, and Europe. 18.2% (n = 2200) of total patients had critical/severe COVID-19 disease. The pooled analysis showed a significant association of COVID-19 disease severity risk with cardiovascular disease (RR: 3.11, p < 0.001), followed by diabetes (RR: 2.06, p < 0.001), hypertension (RR: 1.54, p < 0.001), and smoking (RR: 1.52, p < 006).

Conclusion:

The review involved a sample size of 12037 COVID-19 patients across a wide geographical distribution. The reviewed reports have focused on the association of individual risk assessment of co-morbid conditions with the heightened risk of COVID-19 disease. The present meta-analysis of cumulative risk assessment of co-morbidity from cardiovascular disease, diabetes, hypertension, and smoking signals a novel interpretation of inherent risk factors exacerbating COVID-19 disease severity. Consequently, there exists a definite window of opportunity for increasing survival of COVID-19 patients (with high risk and co-morbid conditions) by timely identification and implementation of appropriately suitable treatment modalities.

Published: September 2021

Background:

Neutrophil to lymphocyte ratio (NLR) is a marker for many inflammatory diseases. Ankylosing spondylitis (AS) is among these inflammatory diseases, and many studies have compared the NLR ratio between patients with AS and healthy controls.

Aim:

This study aims to systematically review and analyze the available evidence about the significance of NLR values in AS.

Method:

Based on Meta-analysis of Observational Studies in Epidemiology (MOOSE) guidelines, we searched Embase, Pubmed, ISI Web of Science, and Scopus databases from inception to August 2020 using (“Ankylosing spondyl* ” OR “Bechterew Disease” OR “Rheumatoid Spondylitis”) AND ((neutrophil* AND lymphocyte*) OR NLR) as key terms of the search strategy. Data selection and extraction were conducted separately by two authors. We appraised the included articles according to the Joanna Briggs checklist. Comprehensive Meta-analysis Version 2 was used for analysis and assessment of publication bias. I2 > 75% and p-value < 0.05 were considered significant.

Result:

In total, 182 studies resulted from a search in all databases. Duplicate removal, title, abstract, and full-text screening yielded 12 related studies, with 11 included in the meta-analysis. Quality assessment was satisfying in all studies. Pooled difference in NLR means value between patients and controls was 0.38 (95% CI: 0.24-0.52, p-value <0.0001). An I2 of 51% and a Cochran Q test p-value of <0.05 indicated moderate heterogeneity; thus, subgroup analysis had no indication. Publication bias was not significant (Funnel plot with an Egger’s intercept of -0.07; p-value=0.95).

Conclusion:

Significant higher amounts of NLR may be strongly indicative of underlying inflammation in AS.
Gait in Patients with Axial Spondyloarthritis: A Systematic Review of the
Literature
Authors: Soulard Julie , Vaillant Jacques , Vuillerme Nicolas
Published: September 2021

:

Axial spondyloarthritis (axSpA) is a chronic inflammatory disease predominantly affecting
the axial skeleton. axSpA includes radiographic (i.e., ankylosing spondylitis (AS)) and non-radiographic
forms (nr-axSpA). Although recent studies have reported that patients with AS have impaired
gait, axSpA’s consequences on gait remain unknown. The present review’s objectives were
to identify: 1) how gait is assessed in patients with axSpA, and 2) what the gait characteristics are
of patients with axSpA.
This systematic review’s protocol was registered in the Prospero database (CRD42020128509).
Three databases were systematically searched using keywords related to axSpA and gait. Two independent
reviewers selected the articles and extracted the data.
The search revealed two hundred titles and abstracts, and two articles were finally included in this
review, comprising a total of 132 patients with axSpA. One of the included studies used the 6 m
maximum gait velocity test (axSpA: 2.2 ± 0.5 m/s), and the other used the six-minute walk test
(axSpA: 414 ± 106 m). Neither study involved a control group to compare gait.
Only two published studies assessed the gait performance of patients with axSpA using clinical
tests. Furthermore, neither of them compared gait performance to healthy controls or differentiated
gait between the AS and nr-axSpA forms of axSPA. The present literature review highlights the
need for future research to learn more about how gait is impaired in different types of patients with
axSpA.

Una visita a la obra de Caballero desde la fenomenología
Authors: Sandoval Rodríguez Oscar Javier
Published: September 2021

La búsqueda de imagen necesaria fue el concepto con que Luis Caballero definió su obra a finales de los 70, desarrollando un tratamiento artístico que inducía una interpretación ambigua de las emociones que podrían experimentar los cuerpos dibujados. Este tratamiento artístico se manifestaba en los recursos pictóricos con que representaba los gestos corporales. Suponiendo que la ambigüedad es una característica que se da en el entendimiento de algo, proponer que en los gestos corporales de la obra de Caballero hay ambigüedad es admitir que esta hace parte de la interpretación de un observador sobre una obra, es decir, los gestos no son ambiguos, lo ambiguo es el entendimiento que sobre ellos ha de tener un observador. El proyecto investigativo en consecuencia se propuso revisitar la obra de Caballero desde la experiencia interpretativa de quien observa, para lo cual fue pertinente abordar la relación espectador/pintura como un evento fenomenológico, esto es, revisar las relaciones que un sujeto entabla con un objeto estético sobre el cual, en la experiencia, se relaciona y puede ser consciente de tres instancias manifestadas: el objeto material (bilk), unos objetos representados (bilksujet) y los aspectos constitutivos de representación (bildobjekt).
Las pugnas de las madres comunitarias por nombrar el trabajo de cuidados
Authors: De León Adriana
Published: September 2021

El escaso valor atribuido al trabajo de las mujeres se remonta a la división sexual de las actividades entre el espacio productivo y el reproductivo, bajo un criterio de valoración del mercado que constituye un índice semántico para considerar lo que es trabajo y lo que no. Esta dualidad valorativa se ha trasladado a las actividades remuneradas, en las que el género ha sido el criterio de diferenciación para ordenar y dar estatus a los trabajos pagados. En Colombia, al trabajo de los cuidados se le han asignado cualidades morales que lo convierten en actividades voluntarias, desinteresadas y gratuitas. Por ello, este artículo se propone hacer un análisis crítico, desde una perspectiva feminista, sobre la reivindicación de los derechos de las mujeres en la disputa por nombrar y reconocer su trabajo. Se ilustrará el caso de las Madres Comunitarias en los cuidados de la niñez al servicio del Estado, explorando los criterios interpretativos de la Corte Constitucional en los últimos treinta años sobre los cuidados como trabajo y la realidad laboral de las cuidadoras.

Published: September 2021

Bu çalışmada partikül madde (PM), karbondioksit (CO2) ve karbon monoksit (CO) seviyeleri farklı özellikteki iç ortamlar (evler) ve eş zamanlı olarak dış ortam havasında 1 yıllık süreyle ölçülmüştür. Çalışma, Çanakkale’nin üç ilçesindeki farklı örnekleme noktalarında aylık bazda yürütülmüştür. Çalışma sonucunda iç ortam hava kalitesinin evden eve farklılık göstermekle beraber, ilçeler arasında da farklılıklar gösterdiği belirlenmiştir. İç ortam havasında ölçülen ortalama PM ve CO2 seviyeleri azalan seviyelerde, sırasıyla, Çan, Lapseki ve Merkez ilçede değişim göstermiştir. İç ortamda ölçülen ortalama sıcaklık 22 °C ve ortalama bağıl nem seviyesi %49 civarındadır. Ölçümü yapılan parametrelerin (PM, CO ve CO2) genel olarak zamansal değişim gösterdiği ve genellikle konsantrasyonların kış aylarında yılın geri kalanına göre daha yüksek olduğu gözlenmiştir. Genel olarak, iç ve dış ortam havasında ölçülen PM, CO ve CO2 düzeyleri istatistiksel olarak anlamlı aylık değişim göstermiştir (p<0,05). Ölçülen hava kalitesi parametreleri için hesaplanan İç ortam/Dış ortam (İ/D) oranlarının genel olarak 1’den büyük olması, PM, CO ve CO2 seviyelerine iç ortam kaynaklarının katkısının önemli olduğuna işaret etmektedir. İç ortamlarda yeterli seviyede havalandırmanın yapılması ile hava sirkülasyonu arttırılarak iç ortam kirletici kaynakların etkisinin azaltılması mümkündür.

Authors: DEMİR Selçuk
Published: September 2021

This study examines the effect of groundwater level ( ) on the seismic site response behavior of a one-layered liquefiable soil using one-dimensional nonlinear numerical analyses. The response of the liquefiable soil was analyzed with the help of DeepSoil open-source software. The calibration of the numerical model was carried out using the results of a centrifuge experiment from the literature. The outcomes of the site response analyses were discussed in terms of peak horizontal acceleration, amplification ratio, excess pore pressure ratio, shear stress-strain behavior, and maximum lateral displacement. Also, additional numerical analyses were performed to investigate relationships between input motion intensity- , frequency content of earthquake motion- , and layer thickness- . It is shown that the seismic site response behavior of the liquefiable soil is highly affected by changes in groundwater levels. Moreover, depending on the location of the groundwater level, the seismic behavior of the liquefiable soil may also change with the increase of the input motion intensity, frequency content, and layer thickness.

Background

Researchers face challenges in patient recruitment, especially for rare, fatal diseases such as amyotrophic lateral sclerosis (ALS). These challenges include obtaining sufficient statistical power as well as meeting eligibility requirements such as age, sex, and study proximity. Similarly, persons with ALS (PALS) face difficulty finding and enrolling in research studies for which they are eligible.

Objective

The aim of this study was to describe how the federal Agency for Toxic Substances and Disease Registry’s (ATSDR) National ALS Registry is linking PALS to scientists who are conducting research, clinical trials, and epidemiological studies.

Methods

Through the Registry’s online research notification mechanism (RNM), PALS can elect to be notified about new research opportunities. This mechanism allows researchers to upload a standardized application outlining their study design and objectives, and proof of Institutional Review Board approval. If the application is approved, ATSDR queries the Registry for PALS meeting the study’s specific eligibility criteria, and then distributes the researcher’s study material and contact information to PALS via email. PALS then need to contact the researcher directly to take part in any research. Such an approach allows ATSDR to protect the confidentiality of Registry enrollees.

Results

From 2013 to 2019, a total of 46 institutions around the United States and abroad have leveraged this tool and over 600,000 emails have been sent, resulting in over 2000 patients conservatively recruited for clinical trials and epidemiological studies. Patients between the ages of 60 and 69 had the highest level of participation, whereas those between the ages of 18 and 39 and aged over 80 had the lowest. More males participated (4170/7030, 59.32%) than females (2860/7030, 40.68%).

Conclusions

The National ALS Registry’s RNM benefits PALS by connecting them to appropriate ALS research. Simultaneously, the system benefits researchers by expediting recruitment, increasing sample size, and efficiently identifying PALS meeting specific eligibility requirements. As more researchers learn about and use this mechanism, both PALS and researchers can hasten research and expand trial options for PALS.
Sandbox reglamentario como fuente de derecho en caso de la disrupción nanotecnológica brasileña
Authors: Pellin Daniela , Engelmann Wilson
Published: September 2021

Consolidar el sandbox regulatorio como fuente de producción normativa para abordar la regulación legal del desarrollo y aplicación de la nanotecnología es el objetivo de este artículo. Dada la paradoja existente entre la nanotecnología y el riesgo, ambos inherentes al desarrollo, la cual se presenta como un problema para la sociedad al tener que lidiar con límites, sería deseable conseguir una regulación legal. Pero, ¿qué regulación legal se está considerando? Ciertamente, a la producida por la intervención social como factor de validación y gestión de los límites de esta paradoja. En este sentido, y retomando otra iniciativa brasileña, el sandbox regulatorio se muestra como una posibilidad de regulación legal del desarrollo y aplicación de la nanotecnología. Para lograr este objetivo, nos basaremos en el proyecto de la Comisión de Valores de Brasil, la cual, junto con el Banco Interamericano de Desarrollo, implementó el proceso normativo denominado sandbox, para regular legalmente las empresas financieras de base tecnológica en una etapa temprana, además de atender las necesidades de control de riesgos y favorecer el desarrollo de la sociedad. La metodología utilizada es hipotético-inductiva, de naturaleza cualitativa y de enfoque sistémico-constructivista. Como técnica de investigación, se utiliza la recolección de datos, documentos, y el análisis de literatura. Los resultados indican que en el caso del desarrollo nanotecnológico y ante la imposibilidad de que el legislador constituyente conozca tal objeto, el sandbox regulatorio puede dar paso a normas dinámicas y democráticas donde todos los actores participan en la construcción del proceso regulatorio, impactando, por tanto, la toma de decisiones sobre la innovación.

The most prevalent pathogen in bone infections is Staphylococcus aureus; its incidence and severity are partially determined by host factors. Prior studies showed that anti-glucosaminidase (Gmd) antibodies are protective in animals, and 93.3 % of patients with culture-confirmed S. aureus osteomyelitis do not have anti-Gmd levels > 10 ng/mL in serum. Infection in patients with high anti-Gmd remains unexplained. Are anti-Gmd antibodies in osteomyelitis patients of the non-opsonising, non-complement-fixing IgG4 isotype? The relative amounts of IgG4 and total IgG against Gmd and 7 other S. aureus antigens: iron-surface determinants (Isd) IsdA, IsdB, and IsdH, amidase (Amd), α-haemolysin (Hla), chemotaxis inhibitory protein from S. aureus (CHIPS), and staphylococcal-complement inhibitor (SCIN) were determined in sera from healthy controls (Ctrl, n = 92), osteomyelitis patients whose surgical treatment resulted in infection control (IC, n = 95) or an adverse outcome (AD, n = 40), and post-mortem (PM, n = 7) blood samples from S. aureus septic-death patients. Anti-Gmd IgG4 levels were generally lower in infected patients compared to controls; however, levels among the infected were higher in AD than IC patients. Anti-IsdA, IsdB and IsdH IgG4 levels were increased in infected patients versus controls, and Jonckheere-Terpstra tests of levels revealed an increasing order of infection (Ctrl < IC < AD < PM) for anti-Isd IgG4 antibodies and a decreasing order of infection (Ctrl > IC > AD > PM) for anti-autolysin (Atl) IgG4 antibodies. Collectively, this does not support an immunosuppressive role of IgG4 in S. aureus osteomyelitis but is consistent with a paradigm of high anti-Isd and low anti-Atl responses in these patients.

Exploration of Hidden Hydrocarbons in Old Wells Magid Field - Sirte Basin, Libya
Authors: Z. A. Alfageh
Published: September 2021

Abstract: It is increasingly important to improve field productivity in today's competitive market. One way to achieve this, is to add new wells which are expensive and time consuming. The other alternative is to identify bypassed hydrocarbons, track changes in saturations and detect movement of reservoir fluid contacts from existing well bores already in place. It is considerably more cost effective and often more environmentally friendly to explore for those hidden hydrocarbons in old wells rather than drill new wells. As the field matures, there is a need to reevaluate the formation in older reservoirs and to focus the development strategy and approach on bypassed oil pockets and depletion levels in producing intervals. The ability to acquire essential logging data behind casing adds a new dimension to cased hole formation evaluation for locating and evaluating potential hydrocarbon zones in a mature field as in Magid field. A basic petrophysical evaluation was performed incorporating the data recorded behind casing by applying {Cased Hole Formation Resistivity Logging (CHFRL)} in each of these wells. Based on the analysis of cased hole formation evaluation results. The un-depleted intervals were commercially exploited adding reserve to the asset.

Published: September 2021

This article looks at the existence of the use of the Malay identity used by regional head candidates in the 2013 Riau Province gubernatorial election. The research method used in this research is the literature study method by analyzing various journals that discuss identity politics and the use of identity in the head election. The results show that in the process, regional representative politics is a strategy that has significance for the victory of Annas Maamun and Arsyad Juliandi Rachman. However, this strategy also needs to be supported by ethnic identity politics for the Riau Coastal and Riau Malay ethnic groups. Thus, this confirms that the use of Riau Malay identity in the implementation of local democracy still serves as an additional strategy in winning the regional head elections in Riau Province.
Authorship and creation for university students
Authors: Zonta Graziele Aline , Zanella Andréa Vieira
Published: September 2021

The aim of this study was to investigate the meanings of creation and the possibilities of authorship for students from two public universities. Reading and writing workshops with students, which were recorded via audio recordings and fieldnotes constituted the field of study. The analyses were based on the theoretical perspectives of Bakhtin and Vygotski and focused, from the students’ point of view, on the social places institutionally occupied by professors and students and the meanings about the academic practices and their consequences for the possibilities of authorship and creation. The results indicate places of inequality in the relationship between peers from public and private education, the individual responsibilization of the students for their trajectories within the university and the signification of academic authorship as responsive to the productivist logic guided by the commodification of scientific production.
