No Future in This Country
Authors: Johnson Andre E.
Published: May 2021

No Future in This Country: The Prophetic Pessimism of Bishop Henry McNeal Turner is a rhetorical history of the public career of Bishop Turner during a critical point in American history—from 1896-1915—the “nadir of race relations.” It was during this period in history that African Americans lost many of the gains during Reconstruction. During this period, America adopted the “separate but equal doctrine,” lynching of African Americans went unabated, the convict leasing systems were on the rise, and the Jim Crow era had begun. In response to this, many African American leaders produced racial uplift narratives that focused on respectability politics. No Future argues that Turner opposed racial uplift and respectability politics as a panacea for what ailed African Americans. His answer was simple—emigration to Africa. While Turner did not see any bright and glorious future for African Americans during this time, he never gave up hope that African Americans would someday use their own agency to carve out a better future for subsequent generations.
No Future argues that Turner does this within the African American Prophetic tradition by focusing in on Turner’s use of prophetic pessimism. In short, while many African American leaders were celebrating how far they had come from slavery, Turner reminded them and the nation that they had not come that far—indeed, in many instances, with conditions continuing to worsen, many felt they were still trapped, if not by slavery itself, then surely the lingering effects of slavery.

In this concluding chapter, Johnson offers a review of the previous chapters. Then the author turns his attention to the movements in the twentieth century that Turner foreshadowed. The chapter closes with some lessons that modern-day readers could learn from Turner.
US-Cuban Musical Relations before and after the Revolution
Authors: Storhoff Timothy P.
Published: May 2021

Chapter One provides the history and context for the rest of the book. The United States and Cuba had a vibrant musical relationship before the Cuban Revolution. When the United States instituted a trade embargo and travel ban on Cuba, musicians continued to seek opportunities for cultural exchange and pushed the boundaries of what travel policies permitted. The chapter outlines how the US-Cuban relationship has changed under various US Presidents, and how musical exchanges have been both stifled and briefly sanctioned under different administrations.
“Your Body Belongs to the State”
Authors: Ward Dan
Published: May 2021

Focusing on Atomic Blonde and Red Sparrow, the chapter explores the familiar forms of dehumanization invoked to reinforce the inherent othering of the rival nation, as well as how Hollywood interpolates the ostensibly progressive image of the self-reliant female action hero in working to shore up perceptions of institutions such as the CIA (with its long and ongoing record of collusion with some of the most reactionary militant and political groups across the globe). The chapter examines these two films within the context of the broader resurgence of Cold War imagery and ideology in contemporary Hollywood.
The Shape of Water and the Cold War Revisited
Authors: Hendershot Cyndy
Published: May 2021

The chapter analyzes Guillermo Del Toro’s Oscar-winning film and its relation to Cold War nostalgia. It claims that The Shape of Water reimagines Cold War America while paying homage to classic tropes of the 1950s. To specify, the film reimagines the classic horror/SF film for a twenty-first-century audience. While the same pathos for the creature exists as in the original that inspired it–The Creature from the Black Lagoon (1954)–Del Toro adds pointed social commentary that would not have been permitted in Hays Code America. The chapter explores how The Shape of Water pays tribute to The Creature from The Black Lagoon while serving as a statement and an update for twenty-first-century filmgoers.
Wipin’, Winin’, and Wukkin’
Authors: Richards-Greaves Gillian
Published: May 2021

This chapter examines rediasporization as a gendered process. It interrogates the ways that African-Guyanese-Americans articulate, construct, and reject Guyanese gendered values through singing, wining (gyrations), and other ritual performances at Come to My Kwe-Kwe celebrations. While gendering is a multilayered process, this chapter specifically focuses on the ways that notions of “real man” and “good” or “proper woman” are negotiated and displayed in Come to My Kwe-Kwe rituals through performances that address domestication, economic providence, and sexuality broadly construed. The chapter also articulates how characteristic innovative performances at Come to My Kwe-Kwe highlight overt and subtle differences between the gender values of the primary African Diaspora in Guyana and those of the secondary diaspora in the United States. The chapter further explores the connections between gendered values in pre-colonial Africa, pre-emancipation Guyana, and the contemporary USA, as African-Guyanese-Americans navigate identity and belonging during processes of rediasporization.
Conclusion: Wholly Fractured, Wholly Whole
Authors: Richards-Greaves Gillian
Published: May 2021

This chapter synthesizes the arguments throughout the book to demonstrate how Come to My Kwe-Kwe has become increasingly important to the process of rediasporization in the African-Guyanese community in New York City, in large part because it constitutes a compound ethnic boundary marker that encompasses other crucial ethnic boundary markers, such as food, music, dance, dress, and religious and gender values. Beneath the consistent negotiation of identities and the policing of ethnic boundaries lies self-preservation. An increasing number of African-Guyanese support Come to My Kwe-Kwe to keep it alive for the next generation in order to prevent complete assimilation. Thus, while the ritual provides an opportunity for African-Guyanese-Americans to embrace their African and Guyanese heritage, it also creates a space for established traditional kweh-kweh practices to be celebrated, challenged, revised, and fractured to accommodate the innovative functions of the ritual, changing performance spaces, and the needs of a secondary diaspora.
“Decisions with Precisions”: New Directions for Hardcore in Washington, DC
Authors: Rapport Evan
Published: May 2021

The music made in Washington DC in the late 1970s and early 1980s fundamentally changed punk. Washington DC was a different environment than the other cities where punk was based in that it was majority Black during this period, with a significant Black presence in the suburbs. The emergence of Bad Brains, an all-Black quartet, at the center of the scene established punk as an authentic form of expression for African Americans and other people of color. Bad Brains and Minor Threat also raised the stakes for musicality in hardcore punk, with complex songs played with virtuosic technique, and they reintroduced elements such as blues-based riffs and rhythmic variations. This chapter also describes the ways in which the punk scene in Washington DC solidified punk’s status as music by and for teenagers and Generation X.
Flannery O’Connor’s Real Estate: Farming Intellectual Property
Authors: Shloss Carol Loeb
Published: May 2021

Carol Shloss takes a literal approach to the subject of legacy by exploring and questioning the legal nature of Flannery O’Connor’s literary estate, a hot topic among many O’Connor scholars. Using “A Circle in the Fire” as a structural metaphor, Shloss argues that the disputes over ownership and property that are present in O’Connor’s fiction echo the reality of Flannery O’Connor’s personal literary estate. Shloss draws on extensive archival research in order to trace the history of O’Connor’s literary estate since the author’s death, while exploring the meaning of property in O’Connor’s work and positing how O’Connor’s writing itself becomes a type of property. Following the succession of O’Connor’s literary executors, Shloss identifies a tendency to move away from creativity about O’Connor and toward an enshirement of her image by a small number of people. Shloss argues that in the end, relaxing the copyright restrictions on O’Connor’s archive would best carry out the wishes of the author.
The clinical laboratory: a decision maker hub
Authors: Salinas María , López-Garrigós Maite , Flores Emilio , Martín Ester , Leiva-Salinas Carlos
Published: May 2021

Objectives

We aimed to share a new laboratory model based on laboratory knowledge, meaningful use of information technology, and partnership with clinicians, to lead the appropriate use of laboratory testing and clinical decision making in the diagnosis of as-yet-undiagnosed disease. More specifically, we evaluate the role of eight different opportunistic interventions to diagnose certain asymptomatic disorders, by means of the automatic registration of appropriate laboratory testing according to different scenarios.

Methods

This is a retrospective longitudinal study to evaluate the impact of laboratory interventions on the diagnosis of different diseases and on patient care, including data from January 2012 to September 2020.

Results

Overall, the above strategies have so far identified 2063 patients with clinically relevant as-yet-undiagnosed disorders who would have otherwise remained occult, such as for instance, primary hyperparathyroidism, diabetes, and hypomagnesemia.

Conclusions

We are facing a new laboratory model, a leading laboratory rather than a passive traditional laboratory, not just to intervene in clinical decision-making, but to make the clinical decision, through the identification of patients with occult disease.
Microsphere molecularly imprinted solid-phase extraction for diazepam analysis using itaconic acid as a monomer in propanol
Authors: Hasanah Aliya Nur , Susanti Ike , Marcellino Marcellino , Maranata Gabriella Josephine , Saputri Febrina Amelia , Pratiwi Rimadani
Published: May 2021

Diazepam (DZP) is a benzodiazepine drug used as an anti-drug and sedative. It is often misused to induce or create euphoria in combination with other drugs (high or fly sensation) or administered alone. So far, screening for DZP abuse with sensitive analytical methods is needed, as its small concentrations make it difficult to detect. Increased sensitivity of the analytical method can be obtained by using a preparation method that selectively separates the analyte from the sample matrix. Molecularly imprinted polymer (MIP) is one of the preparation solutions with good selectivity, specificity, and sensitivity. MIP was made from DZP as a template, itaconic acid, and ethylene glycol dimethacrylate in a composition of 1:4:20. MIP was made by precipitation polymerisation to obtain microsphere polymer type. MIP had a binding capacity value of 0.0557 mg/g and followed the Freundlich isotherm. Application of the microsphere MIP on spiked blood serum resulted in a recovery of 105.63 ± 1.0% for MIP compared to 21.28 ± 0.4% for non-imprinted polymer, with the imprinting factor value reaching 4.96. Hence, MIP DZP with itaconic acid as a functional monomer and propanol as a porogen, fabricated by the precipitation polymerisation method, is a promising sorbent for DZP extraction in biological fluids.
Strong convergence inertial projection algorithm with self-adaptive step size rule for pseudomonotone variational inequalities in Hilbert spaces
Authors: Wairojjana Nopparat , Pakkaranang Nuttapol , Pholasa Nattawut
Published: May 2021

In this paper, we introduce a new algorithm for solving pseudomonotone variational inequalities with a Lipschitz-type condition in a real Hilbert space. The algorithm is constructed around two algorithms: the subgradient extragradient algorithm and the inertial algorithm. The proposed algorithm uses a new step size rule based on local operator information rather than its Lipschitz constant or any other line search scheme and functions without any knowledge of the Lipschitz constant of an operator. The strong convergence of the algorithm is provided. To determine the computational performance of our algorithm, some numerical results are presented.
Ordered fields dense in their real closure and definable convex valuations
Authors: Krapp Lothar Sebastian , Kuhlmann Salma , Lehéricy Gabriel
Published: May 2021

In this paper, we undertake a systematic model- and valuation-theoretic study of the class of ordered fields which are dense in their real closure. We apply this study to determine definable henselian valuations on ordered fields, in the language of ordered rings. In light of our results, we re-examine the Shelah–Hasson Conjecture (specialized to ordered fields) and provide an example limiting its valuation-theoretic conclusions.
Retrieval of digital elevation models from Sentinel-1 radar data – open applications, techniques, and limitations
Authors: Braun Andreas
Published: May 2021

With the launch of Sentinel-1 in 2014, a new era of openly accessible spaceborne radar imagery was begun, and its potential has been demonstrated throughout all fields of applications. However, while interferometric approaches to detect surface deformations are continuously being published, only a few studies address the derivation of digital elevation models (DEMs) from Sentinel-1 data. This is mainly because of the narrow orbital tube, which was primarily designed for subsidence measurements using differential interferometry. Nonetheless, the technical conditions are provided for successful applications involving DEM generation. These are outlined in the first part of this article with a focus on potential error sources and the impact of the most important constraints, namely, temporal and perpendicular baselines. The second part evaluates 21 studies on this topic, their aims, and how they dealt with error sources and the necessity of validation. These studies are then discussed based on the main challenges and potentials including how these can be tackled in the future to lay a solid foundation for scientific discourse.
A Reconsideration and Elaboration of a Previously Proposed Hypothesis for the Origin of the —y of Spanish soy, doy, voy, estoy
Authors: Rini Joel
Published: May 2021

The origin of –y of Sp. soy, doy, voy, estoy remains unresolved to date. The present study reconsiders and elaborates the ‘post-verbal yo hypothesis’, originally proposed by Ford (1911), which has been rejected by most scholars because they have misunderstood it to suggest that the post-verbal subject pronoun yo became atonic and agglutinated to the verb, subsequently reducing to –y. It is suggested here that the phenomenon of ‘leftward palatal spreading’ from the post-verbal subject pronoun yo, with no agglutination nor reduction in form, first produced phonetic variants, e.g., so yo > ['soi̯-'yo], which were later morphologized and raised to allomorphic status before becoming full-fledged morphological variants upon extraction from the new syntagms, e.g., soy yo > soy (yo) > soy.
Fractional-order generalized Legendre wavelets and their applications to fractional Riccati differential equations
Authors: Yuttanan Boonrod , Razzaghi Mohsen , Vo Thieu N.
Published: May 2021

In the present paper, fractional-order generalized Legendre wavelets (FOGLWs) are introduced. We apply the FOGLWs for solving fractional Riccati differential equation. By using the hypergeometric function, we obtain an exact formula for the Riemann–Liouville fractional integral operator (RLFIO) of the FOGLWs. By using this exact formula and the properties of the FOGLWs, we reduce the solution of the fractional Riccati differential equation to the solution of an algebraic system. This algebraic system can be solved effectively. This method gives very accurate results. The given numerical examples support this claim.

Authors: Benahmed Nor-El-Houda , Benabderrahmane Mokhtar , Azzi Rachid , Mouderas Faiza , Aberkane Djoher , Mai Abdesselam Hichem , Bendiabdellah Amel
Published: May 2021

Objectives

Juglans regia L. is largely used by diabetic population, but its bark is scarcely investigated. The major aim of this study was to investigate the effect of the hydro-methanolic extract and fractions of J. regia L. barks on normoglycemic and diabetic rats through the evaluation of some biochemical parameters.

Methods

Phenolic enriched extracts were investigated for their effect on normoglycemic and diabetic rats through the determination of fasting blood glucose levels in short- and long-term. As well as plasma total cholesterol, triglycerides, insulin, urea, creatinine, alanine amino transferase (ALT) and aspartate amino transferase (AST) levels were measured after 28 days of treatment. Furthermore, the phytochemical composition was assessed by standard methods.

Results

Among the different extracts tested, the n-Butanol fraction presented the highest amounts of total phenolic, total flavonoids and flavonol contents (745 ± 0.6 mg GAE g−1, 162 ± 0.78 mg CE g−1 and 56.02 ± 0.92 mg QE g−1, respectively) and it found to be the most effective to decrease plasma total cholesterol, triglycerides and FGLs in treated diabetic rats in both short- and long-term treatment, mainly the dose 200 mg/kg after 28 days of treatment which found to be more effective than glibenclamide. This fraction also revealed pronounced improvement in liver and renal profiles.

Conclusions

J. regia L. barks had an important antidiabetic role similar to the reference glibenclamide. This may be related to the high contents of phenolic compounds.
Professional integrity in maternal – fetal innovation and research: an essential component of perinatal medicine
Authors: McCullough Laurence B. , Coverdale John H. , Chervenak Frank A.
Published: May 2021

Objectives

Clinical innovation and research on maternal–fetal interventions have become an essential for the development of perinatal medicine. In this paper, we present an ethical argument that the professional virtue of integrity should guide perinatal investigators.

Methods

We present an historical account of the professional virtue of integrity and the key distinction that this account requires between intellectual integrity and moral integrity.

Results

We identify implications of both intellectual and moral integrity for innovation, research, prospective oversight, the role of equipoise in randomized clinical trials, and organizational leadership to ensure that perinatal innovation and research are conducted with professional integrity.

Conclusions

Perinatal investigators and those charged with prospective oversight should be guided by the professional virtue of integrity. Leaders in perinatal medicine should create and sustain an organizational culture of professional integrity in fetal centers, where perinatal innovation and research should be conducted.
Comparison of the shear behavior in graphite-epoxy composites evaluated by means of biaxial test and off-axis tension test
Authors: Marín Juan Carlos , Barroso Alberto
Published: May 2021

Characterization of shear behavior in composite materials remains a not fully solved problem. In the last fifty years, many different approaches have been proposed to solve this problem (rail shear, thin-walled tube torsion, off-axis tensile, ±45° tensile, Arcan, Iosipescu, asymmetric four-point bend, plate twist, v-notched rail shear, off-axis flexural, and shear frame), although none of these approaches have achieved an unquestionable solution. For this reason, proposals of alternative methods and comparison between different experimental techniques are of interest. In the present work, the use of cruciform samples with the fiber oriented at 45° with respect to the load directions, and subjected to tension-compression (creating a pure shear stress state at the central part of the samples), is studied. The experimental results of the cruciform samples have been compared with the off-axis tests (with the fiber at 10°) for the same material (AS4/8552), finding a good agreement between the shear experimental curves, especially at the initial part of the curve, where the shear modulus is calculated. Nevertheless, the shear strength value obtained by means of the cruciform specimen has shown to be significantly lower than that obtained using the off-axis test. A Finite Element numerical model of the cruciform specimen has been developed to analyze the stress field of the samples. Numerical results have shown that there is a central area of the cruciform specimens where a pure and uniform shear stress state is developed, which is suitable for the evaluation of the shear constitutive law of the material. It has been observed that there is a (σ
22) stress concentration in the transition between the straight and curved parts of the boundary geometry of the samples, which explain some premature failures of the samples. This premature failure could be avoided with tabs extended up to the beginning of the central part of the sample.
Study of gypsum composites with fine solid aggregates at elevated temperatures
Authors: Doleželová Magdaléna , Scheinherrová Lenka , Vimmrová Alena
Published: May 2021

The structure and behaviour of two gypsum composites after exposition to elevated temperatures were investigated. The silica sand and fine basalt aggregate were used as solid fillers. The changes in structure and composition at temperatures from 50 to 1,000°C were investigated by scanning electron microscopy and X-ray diffraction together with the size and strength of the samples and their pore size distribution. The structure of gypsum matrix changed significantly at 1,000°C in both composites, while the aggregate particles were not changed. It was found that even if the silica sand is considered as less suitable filler at high temperatures because of its volume changes, the gypsum with sand performed better than gypsum with basalt at the highest temperatures, because the shrinkage of the gypsum matrix was compensated by the increase in the volume of aggregate. The final volume change at 1,000°C was 3.5% in composite with silica sand and 6.8% in composite with basalt. The residual compressive strength of both composites was about 9.4%. No cracks appeared in the samples and no spalling was observed.
Testing the Effectiveness of Two Psychosocial Interventions on Socio-Cognitive Risk Factors for HIV/AIDS in Mozambican Women: A Randomized Controlled Trial
Authors: Patrão Ana Luísa , McIntyre Teresa M. , Costa Eleonora C. V. , Matediane Eduardo , Azevedo Vanessa
Published: May 2021

The objective of this study was to evaluate the efficacy of two psychosocial interventions (Didactic and ACCENT) on socio-cognitive risk factors, in vulnerable Mozambican women at risk for HIV/AIDS infection. The study design was a randomized controlled trial on Mozambican women at HIV/AIDS risk (n = 150). The participants were randomized into three groups: Didactic Intervention (experimental group), ACCENT intervention (experimental group), and control group. We used an adapted version of the Women's Health Questionnaire, which includes a series of scales and questionnaires assessing psychosocial relevant dimensions to female protection towards HIV/AIDS: HIV/AIDS knowledge, condom use negotiation self-efficacy, and perceived barriers against safer sex. Both interventions were equally effective in increasing HIV/AIDS knowledge. The ACCENT intervention was especially effective in promoting condom use negotiation self-efficacy and in decreasing perceived barriers against safer sex, essential variables for sexual protection. These results support the adaptation of Western interventions to the African context.

Published: May 2021

Women experiencing incarceration (WEI) in the United States are disproportionately impacted by HIV, yet HIV pre-exposure prophylaxis (PrEP) is underutilized by women in the United States. In order to inform an intervention to promote PrEP initiation during incarceration and facilitate linkage to PrEP care following release from incarceration, we conducted individual, semistructured qualitative interviews with WEI (N = 21) and key stakeholders (N = 14). While WEI had little or no previous knowledge about PrEP, they viewed it as something that would benefit women involved in the criminal justice system. Participants stated that HIV-related stigma and underestimation of HIV risk might serve as barriers to PrEP initiation during incarceration. Participants reported that competing priorities, difficulty scheduling an appointment, and lack of motivation could interfere with linkage to PrEP care in the community. Further, cost, substance use, and difficulty remembering to take the medication were cited most commonly as likely barriers to adherence.
Interspecies Relations: SARS-CoV-2 Spillovers on Mink Farms
Authors: Voelkner Nadine
Published: May 2021

This essay argues for the need for research into multispecies relations at the intersection between international political economy, ecology, and disease emergence. It draws attention to the conditions of intensive agribusiness and modern livestock, which alter human-animal-microbe relations, facilitating the emergence of infectious diseases such as the case of mink farms and COVID-19. It also highlights the impact of infection on animals and farming economies. Through a discussion of the ways anthropogenic activities have historically changed the kinds, scale, and spread of human disease, the essay concludes with an appeal to rethink international political economy.

Published: May 2021

Work From Home (WFH) is an activity that is carried out at home with the flexibility to work both place and time with the help of telecommunications technology. The birth of WFH was caused by the impact of the Covid-19 pandemic, which forced all activities in various fields, including government, business, trade, education, and so on, to be carried out online through the use of technology. One thing that is affected is in the field of education, the teaching and learning process must be carried out online. The problem that occurs is the unpreparedness of the infrastructure and resources in the smooth running of the distance learning process. One of the steps to provide convenience in the distance learning process is to innovate in the field of technology by creating an Android-based M-Learning application with an interactive concept so that it not only provides simple learning but is also designed attractively and interactively so that student participants can interact directly with this M-Learning application. Interactive M-Learning applications are designed with UML (Unified Modeling Language) modeling and translated into applications using Adobe Flash and then implemented on Android mobile devices.­
Analysis of Quality of Service on Internet Networks Using the Burst Method
Authors: Fariz Muhammad , Arifudin Riza
Published: May 2021

The purpose of this research is to make comparisons on the internet network using the application of the Burst method and processed with Quality of Service analysis in which there are parameters of throughput, delay, and jitter. This analysis was carried out because there was a problem with a slow internet network. This happens because there is no configured bandwidth management on the Microtic router and also the unequal distribution of bandwidth when more and more bandwidth users. Burst is one of the bandwidth management methods available on the Microtic router. This study focuses on the implementation of Burst which is applied to one client2 and will be compared with client1 without the application of Burst. Quality of Service analysis is performed to test the parameters of throughput, delay, and jitter on each of the internet networks. After this test is complete, it shows that the results of using the Burst method as a bandwidth regulator, internet network access can be controlled and each client gets the bandwidth evenly as needed. The work result using Burst is more optimal than performance without using Burst. By using Burst the number of packets lost and failed transactions is reduced by more than 70%.

Published: May 2021

Bariatric surgery is still the most effective long-term weight-loss therapy. Recent data indicate that surgical outcomes may be affected by diurnal food intake patterns. In this study, we aimed to investigate how surgery-induced metabolic adaptations (i.e. weight loss) interact with circadian clock function. For that reason, vertical sleeve gastrectomy (VSG) was performed in obese mice and rhythms in behavior, tissue rhythmicity, and white adipose tissue transcriptome were evaluated. VSG under constant darkness conditions led to a maximum weight loss of 18% compared to a loss of 3% after sham surgery. Post-surgical weight development was characterized by two distinct intervals of catabolic and subsequent anabolic metabolic state. Locomotor activity was not affected. However, VSG significantly increased active phase meal frequency in the anabolic state. No significant effects on clock gene rhythmicity were detected in adrenal and white adipose tissue (WAT) explant cultures. Transcriptome rhythm analyses of subcutaneous WAT revealed a reduction of cycling genes after VSG (sham: 2493 vs VSG: 1013) independent of sustained rhythms in core clock gene expression. This may be a consequence of weight loss-induced morphological reconstruction of WAT that overwrites the direct influence of the local clock machinery on the transcriptome. However, VSG altered rhythmic transcriptional regulation of WAT lipid metabolism pathways. Thus, our data suggest a reorganization of diurnal metabolic rhythms after VSG downstream of the molecular clock machinery.

Published: May 2021

The objective of this research was to study the feasibility of producing biodegradable thermoplastic starch rice-husk composites. The effect of different types of mineral fillers on the various properties of thermoplastic starch composites filled with rice-husk flour, an agricultural waste residue, was studied. The mineral fillers aluminum trihydrate (ATH), magnesium dihydroxide (MDH), nanoparticulate MDH, and nanoclay were studied. It was found that the addition of the mineral fillers and especially nanofillers improved the dimensional stability and the mechanical properties of the composites, while decreasing their biodegradability. The thermogravimetric analysis (TGA) showed that substituting mineral fillers for some part of the lignocellulosic component increased the extents of weight-loss in the first and second steps, but decreased the weight-loss in the last step. This substitution also led to a slight decrease in the thermal decomposition temperatures at the curve peaks.

Published: May 2021

Three approaches were examined for the reutilization of cold caustic extraction (CCE) lye. The term CCE lye refers here to the used NaOH solution with relatively high alkali content, which could be wasted if not reused properly. The results showed that CCE lye can be effectively applied in deinking, alkaline hydrogen peroxide bleaching, and oxygen delignification processes. The CCE lye improved the physical strength of the dried sheet of pulp, as the tensile index increased by 17.9% to 40.5%, the tear index increased by 2.9% to 22.2%, and the burst index increased by 10.5% to 41.0%. The results demonstrated the feasibility of integrating the CCE process of dissolving pulp production with regular pulping and bleaching processes.
Indian Stock Market during the COVID-19 Pandemic: Vulnerable or Resilient?: Sectoral analysis
Authors: Shankar Rishika , Dubey Priti
Published: May 2021

This study examines the impact of COVID-19 pandemic on the performance of Indian stock market, measured by daily average returns and trading volume. The analysis is aimed at discovering the vulnerability of the general market as well as nine crucial sectors to the pandemic while also checking the impact on overall volatility in the market. The findings suggest that all the sectors followed a consistent pattern of being significantly impacted by the pandemic. However, the benchmark index remained resilient in the context of average returns. The entire market witnessed decreased returns and increased liquidity, which is explained by reduced volatility in the market.
Is CSR Expenditure Relevant to the Firms in India?
Authors: Garg Arunesh , Gupta Pradeep Kumar , Bhullar Pritpal Singh
Published: May 2021

The present study examines the relevance of Corporate Social Responsibility (CSR) expenditure to the firms in the mandatory regime in India. The paper has its theoretical basis from the instrumental aspect of the Stakeholder theory, which assumes a positive influence of CSR over financial performance. Therefore, the study hypothesizes that the firms which fulfill the CSR expenditure requirement will exhibit higher stock returns and lower systematic risk. Since India mandated CSR in the year 2014, the data of four years (2016-2019) for the sample of 426 National Stock Exchange (NSE) listed Indian firms are taken to employ the OLS regression method. The CSR expenditure in the mandatory regime was not found to be relevant to the firms because of an insignificant positive impact of mandatory CSR expenditure on stock returns. Thus, the instrumental aspect is not supported by the findings. However, the findings indicate a decrease in the systematic risk of the firms. Only a few studies in India investigated this phenomenon in the mandatory regime. Further, the contributions of the study to the CSR literature are fairly useful from the perspective of firms, investors, policy-makers, regulators, scholars, and countries that are planning for legislating CSR.

La pandemia de covid-19 golpeó a Chile en medio de una crisis político social caracterizada por una dura confrontación entre la ciudadanía y sus instituciones, además, de una profunda crítica al modelo económico instaurado por la dictadura de Augusto Pinochetcuyo sustento institucional es la Constitución de 1980. El gobierno derechista de Sebastián Piñera intentó sacar réditos políticos de la pandemia del coronavirus, utilizarla para reafirmarse en el poder, pero la emergencia sanitaria evidenció aún más las profundas desigualdades sociales que subsisten en el país a 30 años de la recuperación de la democracia. Chile aparece doblemente golpeado: por un lado, enfrenta una profunda fractura social y, por otro lado, sufre la debacle del coronavirus. En este complejo cuadro, los chilenos deberán resolver, mediante un plebiscito, si convocan o no a una convención constituyente para sepultar definitivamente la Constitución de Pinochet. Este artículo es una aproximación a ese escenario.
Learning about the past through food
Authors: Hastorf Christine A.
Published: May 2021

Food plays a central role in human life, both past and present. For much of human history, obtaining a sufficient amount of food was a daily priority. Eating not only engages the senses, but it is a vital form of social engagement, creating important and crucial social and familial bonds. The various steps and stages required in the procurement, production, preparation and consumption of food all leave their traces in the archaeological record. Much of the material culture we encounter at archaeological sites, from the macro to the micro, can in some way be connected to food. Archaeologists continue to develop new techniques and technologies that bring us closer to the ways in which people interacted with food, in its many variant forms, in the past. This thematic essay does not seek to provide a thorough review of archaeological food studies, but rather, in the words of Levi-Strauss, to provide something, like food, that is ‘good to think with’. The goal is to present some of the traditional research questions and methods surrounding food, along with explorations of some newer perspectives. It highlights the importance of environmental archaeology and archaeological sciences, and demonstrates how the integration of macro- and microremains, through microscopic techniques and the analysis of residues found on ceramics, can aid in our understanding of a wide range of foodways practices, from fermentation to storage, cooking and consumption. Now is the time to reorient both past and future research, to more clearly address the rich and engaging topic of what and how our ancestors ate, why they did so, and what every part of this great process might have meant to them.

«El proceso de enseñanza y el éxito del aprendizaje están estrechamente vinculados a factores cognitivos y motivacionales. Este estudio tuvo como propósito poner a prueba un modelo multinivel en estudiantes de Educación Superior sobre la relación de la organización docente y las dimensiones del grit, mediada por la competencia percibida. Participaron 3.033 estudiantes de cinco países, a los que se les midió la utilidad y organización del docente, la competencia y el grit. Los resultados muestran que, a nivel individual, la organización por parte del profesorado centrada en la utilidad se relacionó positivamente con el grit del estudiante cuando estaba mediada por la competencia percibida. Se sugiere que el profesor mejore su tarea organizativa docente, pues genera mayores logros en el estudiante a través del impacto positivo sobre su competencia.

El avance tecnológico de los dispositivos móviles ha cambiado significativamente la manera en que los estudiantes se comunican e interactúan. Se presenta una investigación cuya finalidad es analizar el nivel de competencia digital, en el área de comunicación, que tienen escolares españoles de 12-16 años, y determinar si el uso de WhatsApp y correo electrónico influyen en él. Se empleó una metodología cuantitativa, se trabajó con una muestra de 807 estudiantes y se utilizó una prueba de resolución de problemas para la recogida de datos. Los resultados evidencian que el uso de estas herramientas comunicativas no mejora el nivel competencial.
Coordenação de Curso de Graduação – desafios e tensões na atuação profissional do professor universitário
Authors: Medeiros Emerson Augusto de
Published: May 2021

Este escrito tem como objeto de estudo a coordenação de curso de graduação. Pretende levantar reflexões acerca de desafios e tensões na atuação profissional do professor universitário no âmbito da coordenação de curso de graduação na Educação Superior. Em termos metodológicos, se configura como um registro teórico-experiencial, uma vez que se ancora na literatura acadêmica, nacional e internacional, acerca da docência universitária e na experiência vivida no contexto da coordenação do Curso de Licenciatura Interdisciplinar em Educação do Campo da Universidade Federal Rural do Semi-Árido, nos anos de 2014 a 2016. Como apontamentos conclusivos, enfatiza que a atuação profissional do professor universitário, na coordenação de curso de graduação, está condicionada à cultura organizacional das instituições universitárias e às relações de poder existentes em cada contexto. Além disso, reforça a necessidade de formação, especialmente na área de gestão universitária, para a atuação na coordenação de curso de graduação, bem como a demanda de apoio/suporte técnico-administrativo, dos departamentos e dos centros acadêmicos, entre outros, no trabalho diário da coordenação. A ausência desse apoio/suporte sobrecarrega o coordenador de curso e precariza sua atuação profissional na Educação Superior.
Franqueza, filosofia e educação: estética da existência e parrhesía a partir do seriado The Good Doctor
Authors: Mota Fernanda Antonia Barbosa da , Silva Heraldo Aparecido
Published: May 2021

ResumoO propósito deste trabalho é apresentar algumas reflexões sobre o seriado The Good Doctor a partir de conceitos filosóficos e educacionais de Michel Foucault. Inicialmente, o estudo descreve as linhas gerais do seriado dramático. Em seguida, apresenta as noções teóricas foucaultianas de estética da existência e parrhesía. Posteriormente, é estabelecida a articulação entre alguns tópicos da referida serie e os conceitos foucaultianos que servem de aporte teórico analítico. Os principais aportes teóricos são extraídos de autores como: Muchail (2004; 2012), Veiga-Neto (2011), (Gallo, 2012), Foucault (2004; 2006; 2012; 2013), dentre outros. O resultado da discussão evidencia que o uso de elementos não teóricos, como o seriado televisivo no presente caso, constitui um recurso interessante como introdução à discussão de alguns temas acadêmicos complexos.
Arte, política e educação ambiental: a contribuição do pensamento de Theodor Adorno
Authors: Souza Heluane Aparecida Lemos de , Cavalari Rosa Maria Feiteiro
Published: May 2021

A relação sociedade-natureza decorre, principalmente, da concepção de natureza que construímos ou, como afirma Bornheim, do “modo como o homem torna a natureza presente” (1985, p.18). A partir de Descartes (1596-1650) e Bacon (1561-1626) o conhecimento científico passou a ter uma função intervencionista, tornando-se necessário conhecer a natureza para dominá-la. A esta perspectiva de conhecimento a “Teoria Crítica” elaborada pela Escola de Frankfurt se opõe radicalmente. Da mesma forma, afirmamos que a atual crise socioambiental não pode ser resolvida apenas por meio da ciência e da tecnologia, embora não possamos abrir mão de sua contribuição, mas torna-se, fundamentalmente, uma questão política (BORNHEIM, 1985). Neste sentido, compreendemos a Educação e a Arte, em uma perspectiva política, fundamentais para a transformação da realidade. A presente pesquisa, de abordagem qualitativa e natureza bibliográfica, tem como objetivo analisar a arte, na perspectiva de Theodor Adorno, bem como identificar possíveis contribuições para a Educação Ambiental. Compreendemos que, para Adorno, a arte é uma forma de conhecimento, que possibilita uma experiência estética, e uma práxis política. Enquanto forma de conhecimento, a arte é, dialeticamente, "mímese" e "racionalidade". Da mesma forma, é condição para o estabelecimento da “experiência estética da natureza”, que permite que esta seja compreendida como fenômeno e experienciada através da imagem. Por fim, a arte relaciona-se com a sociedade não apenas pela sua produção e origem de seu conteúdo mas, enquanto arte autônoma, ocupa posição antagônica à sociedade. A arte, tal como proposta por Adorno, nos possibilita aproximá-la da proposta de Carvalho (1989; 2006) para EA.

O objeto do trabalho em testilha é a possibilidade da criação de elementos para o desenvolvimento de um regime transnacional sustentável de proteção jurídica dos conhecimentos tradicionais associados à biodiversidade amazônica, considerando a imprescindível inter-relação dos conhecimentos tradicionais dos povos da Amazônia com a sustentabilidade. Comporta necessariamente um tratamento transdisciplinar, pois as categorias de construções da realidade são diversas, e, embora diferentes, encontram-se profundamente interligadas ou interdependentes. O método utilizado na fase de investigação e na fase de tratamento dos dados foi o indutivo. Nas diversas fases da pesquisa foram acionadas as técnicas do referente, da categoria, do conceito operacional, da pesquisa bibliográfica e do fichamento. O desenvolvimento do tema pautou-se pela persecução dos objetivos geral e específicos que nortearam a produção. O relatório se encerra com as conclusões e consubstancia o resultado de todos os achados da pesquisa acadêmica, findando por confirmar a hipótese inicialmente concebida, tendo, alfim, alcançado os elementos para o desenvolvimento de um regime transnacional sustentável de proteção jurídica dos conhecimentos tradicionais associados à biodiversidade amazônica.
