Efeito do Incremento da Produção de Energias Renováveis Intermitentes nos Preços da Eletricidade
Authors: C. R. Oliveira Blandina , Fortunato Adelino
Published: October 2021

Despite increasing deployment of intermittent renewable energies at lower generation costs, wholesale electricity price has been falling while retail electricity prices go up. This has triggered the debate on the cost-effectiveness of this source of energy. Therefore, the aim of this paper is to present a literature survey on the effect of intermittent renewable energy generation on electricity prices. Researches have used different methodological approaches, different periods and countries to examine the impacts of intermittent renewable energy on electricity prices. Most of the studies found evidence of the merit-order effect, which means that an increase in intermittent source generation would reduce the spot electricity market price. Finally, the few studies that address the retail market found that retail electricity could either increase or decrease.
Automation and control of greenhouse implemented technologies: a review
Authors: Osorio-Luna David Felipe , Molina-Ruiz Paola Andrea
Published: October 2021

Protected agriculture is a way of producing food by creating a microclimate that allows protecting a crop from the risks inherent in free exposure; in this sense, its purpose is to guarantee the optimal and appropriate conditions of internal variables to generate reproduction, development and growth of plants with quality and commercial opportunity. In this way, the application of technologies to crops has extended considerably due to the need to optimize this productive alternative: in this respect, there are multiple scattered investigations based on particular designs of elements such as greenhouses. Therefore, this article shows a review on protected agriculture aimed at the automation of greenhouses in countries that have implemented emerging technologies in this field and the consequent control generated in the stages of the production cycle through sensors, actuators, specific covers or robots designed to perform tasks such as spraying or harvesting, among others. Key analysis elements are presented on the modeling of the phenomenon that underlies the implementations, so that systems with the necessary adaptation are achieved for any crop, taking into account its type, cost and location, defining a baseline on the technologies that make it functional and efficient.

Published: October 2021

Some methods that were developed throughout history to find derivatives from Apolonio de Perga to Cauchy are presented, then itineraries are proposed for the introduction of the derivative in the curriculum: addressing positions of the theory of Action, Process, Object and Scheme (APOE) and the tools proposed by the known as the Onto-Semiotic Approach (OSA), for elements of the derivative before the limit and limits before derivatives. From these, semiotic representations are proposed that allow to approach the derivative (numerical, algebraic, formal, geometric, infinitesimal, local, variational and computational related approximation). Finding that the concept as taught today does not coincide with the development of its genesis and that a way of understanding the concept of derivatives from the use of treatments and conversions of registers of representation.

Sobre el concepto gauge, global y local, y su implementación en física
Authors: Rozo-Clavijo Mauricio
Published: October 2021

Se realiza un análisis sobre el concepto gauge, global y local, ilustrando los aspectos más importantes sobre la manera de proceder para el establecimiento de la simetría gauge en electrodinámica clásica, mecánica cuántica y electrodinámica cuántica, mostrando cómo la simetría gauge produce un resultado que es físicamente significativo. Bajo este contexto, se implementa el concepto gauge haciendo uso del formalismo lagrangiano y exigiendo su invariancia bajo un grupo de simetría. Además, se bordan las ideas de Yang y Mills apoyadas en el grupo no abeliano SU (2) como una primera explicación sobre la dinámica de la interacción entre el protón y neutrón a partir de la conservación del isoespín. Este análisis revela como el concepto gauge se convierte en un paradigma para la construcción de explicaciones alrededor de los fenómenos a nivel atómico; explicación que se considera de difícil comprensión por parte de los estudiantes, lo que permite generar una forma alternativa, didáctica y robusta de abordar el tema para favorecer la adquisición de un conocimiento sobre los principios subyacentes en los que se fundamenta la física contemporánea.
Database isolation by scheduling
Authors: Gaffney Kevin P. , Claus Robert , Patel Jignesh M.
Published: October 2021

Transaction isolation is conventionally achieved by restricting access to the physical items in a database. To maximize performance, isolation functionality is often packaged with recovery, I/O, and data access methods in a monolithic transactional storage manager. While this design has historically afforded high performance in online transaction processing systems, industry trends indicate a growing need for a new approach in which intertwined components of the transactional storage manager are disaggregated into modular services. This paper presents a new method to modularize the isolation component. Our work builds on predicate locking, an isolation mechanism that enables this modularization by locking logical rather than physical items in a database. Predicate locking is rarely used as the core isolation mechanism because of its high theoretical complexity and perceived overhead. However, we show that this overhead can be substantially reduced in practice by optimizing for common predicate structures.

We present DIBS, a transaction scheduler that employs our predicate locking optimizations to guarantee isolation as a modular service. We evaluate the performance of DIBS as the sole isolation mechanism in a data processing system. In this setting, DIBS scales up to 10.5 million transactions per second on a TATP workload. We also explore how DIBS can be applied to existing database systems to increase transaction throughput. DIBS reduces per-transaction file system writes by 90% on TATP in SQLite, resulting in a 3X improvement in throughput. Finally, DIBS reduces row contention on YCSB in MySQL, providing serializable isolation with a 1.4X improvement in throughput.
Viper
Authors: Benson Lawrence , Makait Hendrik , Rabl Tilmann
Published: October 2021

Key-value stores (KVSs) have found wide application in modern software systems. For persistence, their data resides in slow secondary storage, which requires KVSs to employ various techniques to increase their read and write performance from and to the underlying medium. Emerging persistent memory (PMem) technologies offer data persistence at close-to-DRAM speed, making them a promising alternative to classical disk-based storage. However, simply drop-in replacing existing storage with PMem does not yield good results, as block-based access behaves differently in PMem than on disk and ignores PMem's byte addressability, layout, and unique performance characteristics. In this paper, we propose three PMem-specific access patterns and implement them in a hybrid PMem-DRAM KVS called
Viper.
We employ a DRAM-based hash index and a PMem-aware storage layout to utilize the random-write speed of DRAM and efficient sequential-write performance PMem. Our evaluation shows that Viper significantly outperforms existing KVSs for core KVS operations while providing full data persistence. Moreover, Viper outperforms existing PMem-only, hybrid, and disk-based KVSs by 4--18X for write workloads, while matching or surpassing their get performance.
Comparison of the QuikRead go® point-of-care faecal immunochemical test for haemoglobin with the FOB Gold Wide® laboratory analyser to diagnose colorectal cancer in symptomatic patients
Authors: Maclean William , Zahoor Zahida , O’Driscoll Shane , Piggott Carolyn , Whyte Martin B. , Rockall Timothy , Jourdan Iain , Benton Sally C.
Published: October 2021

Objectives

Faecal immunochemical testing for haemoglobin (FIT) is used to triage patients for colonic investigations. Point-of-care (POC) FIT devices on the market have limited data for their diagnostic accuracy for colorectal cancer (CRC). Here, a POC FIT device is compared with a laboratory-based FIT system using patient collected samples from the urgent referral pathway for suspected CRC.

Methods

A prospective, observational cohort study. Patients collected two samples from the same stool. These were measured by POC QuikRead go® (Aidian Oy, Espoo, Finland) and laboratory-based FOB Gold Wide® (Sentinel Diagnostics, Italy). Faecal haemoglobin <10 μg haemoglobin/g of faeces was considered as negative. At this threshold, comparisons between the two systems were made by calculating percentage agreement and Cohen’s kappa coefficient. Proportion of negative results were compared with Chi squared testing. Sensitivities for CRC were calculated.

Results

A total of 629 included patients provided paired samples for FIT to compare the QuikRead go® and FOB Gold Wide®. The agreement around the negative threshold was 83.0% and Cohen’s kappa coefficient was 0.54. The QuikRead go® reported 440/629 (70.0% of samples) as negative compared to 523/629 (83.1%) for the FOB Gold Wide®, this difference was significant (p-value<0.001). Sensitivities for CRC detection by the QuikRead go® and FOB Gold Wide® were 92.9% (95% confidence interval (CI): 68.5–98.7%) and 100% (CI: 78.5–100%) respectively.

Conclusions

Both systems were accurate in their ability to detect CRC. Whilst good agreement around the negative threshold was identified, more patients would be triaged to further colonic investigation if using the QuikRead go®.
The discursive construction of accountability for communicative action to citizens: A contrastive analysis across Israeli and British media discourse
Authors: Weizman Elda , Fetzer Anita
Published: October 2021

This paper sets up to show how accountability for communicative action is constructed in online journalism as an object of talk, comparing British English and Israeli Hebrew discourse communities. The analysis utilizes a discourse-pragmatic frame of reference supplemented by cognitive semantics and corpus-assisted tools. The discussion draws on data collected from the websites of The Guardian and The Daily Telegraph, Ha’aretz and Ynet. Focusing on self- and other-positioning of commenters and columnists as citizens, we explore how the accountability of the elite for communicative action and the accountability of their actions to citizens are discursively constructed by ordinary persons (in their role as commenters) and by non-ordinary persons (in their role as columnists, including journalists, experts and authors). The analysis indicates conceptual similarities coupled with discursive differences between the discourse communities under study.

Published: October 2021

Objectives

The current pandemic caused by Severe Acute Respiratory Syndrome Corona-Virus 2 (SARS-CoV-2) has become a global health menace with significant morbidity and mortality besides huge socioeconomic implications. Despite the approval of few vaccines for the prevention of the disease, the discovery of safe and effective countermeasures especially from natural sources is of paramount importance, as the number of cases continues escalating. Arq Ajīb has long been used for various diseases and its ingredients have been reported for antiviral, antimicrobial, antipyretic, anti-inflammatory, antioxidant activities. The present study investigates the inhibitory effect of phytocompound of Arq Ajīb on potential drug targets of SARS-CoV-2.

Methods

The structures of phytocompounds present in Arq Ajīb were retrieved from PubChem database and some were illustrated using Marvin Sketch. SARS-CoV-2 S glycoprotein (PDB ID: 6LZG) and 3CLpro (PDB ID: 7BQY) were selected as the target protein. Dock Prep module in UCSF Chimera software was used for receptor structure processing. AutoDock Vina was used to calculate the binding affinities between the protein and ligands and to predict most promising compounds with best scores.

Results

Molecular docking results predicted that the phytocompounds of Arq Ajīb had good binding affinity and interaction with S glycoprotein and 3CLpro. Quercetin and Isorhoifolin from Mentha arvensis were identified as promising candidates with the potential to interact with 3CLpro and spike glycoprotein and inhibit the viral replication and its entry into the host.

Conclusions

Arq Ajīb may prove valuable for developing novel therapeutic candidate for COVID-19; however, it has to be substantiated further with in-vitro and in-vivo studies.

Published: October 2021

Pediatric adrenocortical tumors are rare and heterogeneous endocrine malignancies.

Objectives

To report clinical, biochemical, and histological features, staging, and therapeutic interventions in a cohort of 28 patients treated at a single tertiary center.

Methods

A retrospective review of medical records of children with PACT (diagnosed before <18 years of age) followed between 1987–2018 at Hospital de Pediatría Garrahan, Buenos Aires, Argentina.

Results

Mean age at diagnosis was 4.6 years (range, 0.3–17.3 years) and median follow-up was 4.17 years (range, 0–12 years). Female to male ratio was 2.5:1. Signs and symptoms that prompted medical intervention were hormonal overproduction (57%), abdominal complaints (36%), and hypertensive encephalopathy (7%). In patients with clinically virilizing tumors (n=16) mean height standard deviation score (SDS) and bone age advance were significantly higher while body mass index (BMI) SDS was significantly lower than in those with clinical Cushing’s (n=10) (p<0.05). Serum dehydroepiandrosterone sulfate (DHEAS) levels were significantly higher in stage IV than in stage I (p=0.03). Total adrenalectomy was performed in 26 patients. Eight patients (stage III-IV) received adjuvant chemotherapy. Five-year overall and disease-free survival were 100% for ST I-II, and 51% (95% CI 21–82) and 33% (95% CI 1.2–65) for ST III-IV, respectively (p=0.002). No statistical difference was found when comparing 2-year parameters with and without adjuvant chemotherapy.

Conclusions

Height SDS and BMI SDS seem to mirror hormonal secretion in pediatric adrenocortical tumors. Higher DHEAS levels were found in patients with more advanced disease. Further large-scale studies are needed to validate a possible role for DHEAS as a biochemical marker of tumor stage and to draw robust conclusions on the use of adjuvant chemotherapy.
The maturing moral perception of crime: The development of moral correspondence and its association with emerging adults’ delinquent involvement
Authors: Kessler Georg
Published: October 2021

Purpose: This study scrutinizes Situational Action Theory’s (SAT) implications of how internal and external criminogenic factors concerning the rule of moral correspondence develop conjointly over the life-course and how this affects offending during emerging adulthood.Objectives: The main objective is to empirically explore whether the development of moral correspondence displays heterogeneity that can be theoretically linked to heterogeneous offending developments. Additionally, the paper also discusses unexpected co-occurrences arising specifically for the new opportunity structures to commit crimes in emerging adulthood via the broader developmental perspective proposed by the Developmental Ecological Action model of SAT (DEA).Methods: Results from two separate classification models (latent class growth analysis and repeated-measurement latent class analysis) following a German non-offender sample’s (N = 1810) transition between adolescence and emerging adulthood (ages 14 to 28) are cross-tabulated.Results: Five moral correspondence pathways differentiated by the timing, speed and completeness of achieving pro-social states can be extracted. The longer individuals resist this maturitation process during adolescence, the higher their chances are to follow a trajectory during emerging adulthood characterized by proclivities for youth crimes. However, these also follow a diminishing trend. Contrary, rising trajectories fueled by proclivities to commit adult crimes are less often associated by a remiss to maturity. Social selection into specific activity fields seems to play an important role in the availability and accessibility to either type of crime, thus, offering an explanation for these diverging results.Conclusion: SAT and its developmental framework DEA serve as useful blueprints to map the development of changes in crime and its related causes even with non-situational data through its analytical rigor to integrate micro-, meso-, and macro-levels of explanation.
Resident stem cells in the heart

Published: October 2021

Cardiovascular disease is the leading cause of mobility and morality worldwide, in which the ischemic heart disease is the most common type of the diseases. During last decade, a major progress in the study of the pathogenesis of heart disease has been achieved. For example, the discovery of adult stem/progenitor cells in the heart and vessel tissues may play a role in tissue regeneration. However, the issue of 31 retractions for cardiac stem cell work has caused a “storm of trust” in the heart stem cell field, in which both founders and scientists have become cautious and conservative in stem cell research of the heart. Despite that the existence of adult cardiac stem cells has been denied, recent studies confirmed that there are many other resident stem/progenitor cells in adult heart. Although these cells cannot differentiate into cardiomyocytes, the role they played in heart repair after injury should not be ignored. The purpose of this short article is to briefly review the current research progress in resident stem/progenitor cells in the heart, to discuss how they function during cardiac repair and to point out unanswered questions in the research field.
The role of caveolae in endothelial dysfunction
Authors: He Jinlong , Cui Zhen , Zhu Yi
Published: October 2021

Caveolae, the specialized cell-surface plasma membrane invaginations which are abundant in endothelial cells, play critical roles in regulating various cellular processes, including cholesterol homeostasis, nitric oxide production, and signal transduction. Endothelial caveolae serve as a membrane platform for compartmentalization, modulation, and integration of signal events associated with endothelial nitric oxide synthase, ATP synthase β, and integrins, which are involved in the regulation of endothelial dysfunction and related cardiovascular diseases, such as atherosclerosis and hypertension. Furthermore, these dynamic microdomains on cell membrane are modulated by various extracellular stimuli, including cholesterol and flow shear stress. In this brief review, we summarize the critical roles of caveolae in the orchestration of endothelial function based on recent findings as well as our work over the past two decades.

Authors: Manikandan Arumugam , Omkumar Meenakshi Sundaram , Mohanavel Vinayagam
Published: October 2021

In the current research work, an Al-Si-Mg aluminum alloy-based composite (AMCs) was prepared via stir casting. The AA6082 matrix was incorporated with 0, 3, 6 and 9 wt.-% zirconium diboride (ZrB2) particles for manufacturing composites. The manufactured AA6082/ZrB2 composites were evaluated by employing scanning electron microscope (SEM) and X-ray diffraction (XRD). Flexural strength, macro-hardness and wear rate of the composites were examined. XRD confirms the development of ZrB2 peaks and also proves that no reaction products are found in the AMCs. The SEM examination depicts the homogeneous dissemination of ZrB2 in the Al alloy. The tribological and mechanical characterization of the AMCs improved after the inclusion of ZrB2 contents. The experimental outcomes attained indicate that the tribological and mechanical behavior of the AMCs was enriched by an escalation in mass proportionate to the ZrB2 filler content.
C.A.P.I. Project in the Making: 3D Applications at Poggio Imperiale Between Materiality and Virtual Reality (Poggibonsi, IT)
Authors: Bertoldi Stefano
Published: October 2021

The archaeological project on the hill of Poggio Imperiale began in 1992. From the beginning this project was characterized by intense experimentation with a range of IT applications. During 2014, the University of Siena began a new project focused on the valorisation of archaeological data with the creation of an Open-Air Museum of the Carolingian village, one of the archaeological phases of the settlement. Over the last several years, the use of three-dimensional (3D) data in archaeology has increased exponentially due to the application of photogrammetry to record every stratigraphic unit. This ever-increasing amount of data fostered the development of the C.A.P.I. project (Collina Accessibile di Poggio Imperiale – Accessibility of the Hill of Poggio Imperiale), which involved the construction of a 3D model of the archaeological area of Poggio Imperiale. The project modeled the three main life stages of the hill using 3D computer graphics. Virtual tours can be experienced through PCs, tablets, smartphones, and even virtual reality headsets, offering users a fully immersive experience. However, virtual reality will not be a replacement for the materiality of the archaeological site. On the contrary, it will provide an additional tool to make the site accessible and inclusive to any potential visitor, regardless of physical distance, physical ability, or time zone.
Surviving a natural disaster as a semiotic reformation of the self and worldview
Authors: Delante Nimrod L.
Published: October 2021

Theoretically, this study is framed within the semiotic tradition of communication theory, which theorizes communication as the intersubjective mediation by signs. Methodologically, this study is guided by Peirce’s semiotic ideas, especially his writing about the commens and commind, or the sign and the object, and the power of a community (constitutive of the self as researcher and the self as one with participants) as the final interpretant performing the process of sensemaking. Results showed how the survivors of a natural calamity symbolically interacted with such calamity, and how this led to a reformation of the way they view themselves and the world. The survivors’ symbolic images captured in narratives, in sketches and drawings, and in poetry helped them to reframe their sense of self and their worldview by believing in common sense and intuition, and by valuing the power of courage, initiative, preparedness, hope, and resilience. An unfortunate irony emerged in their symbolic interaction with the disaster such that their sinning and self-inflicted blame made them think they were worthy of punishment. Nonetheless, this unfortunate irony will change if the survivors continue to reflect on their civic roles, interrogate their environmental and political contexts, and expand their awareness and social consciousness. As these unfold, the survivors will be able to accomplish empowerment, emancipation, and an independent mind.

Predictive structure or paradigm size? Investigating the effects of i-complexity and e-complexity on the learnability of morphological systems
Authors: Johnson Tamar , Gao Kexin , Smith Kenny , Rabagliati Hugh , Culbertson Jennifer
Published: October 2021

Research on cross-linguistic differences in morphological paradigms reveals a wide range of variation on many dimensions, including the number of categories expressed, the number of unique forms, and the number of inflectional classes. However, in an influential paper, Ackerman & Malouf (2013) argue that there is one dimension on which languages do not differ widely: in predictive structure. Predictive structure in a paradigm describes the extent to which forms predict each other, called i-complexity. Ackerman & Malouf (2013) show that although languages differ according to measure of surface paradigm complexity, called e-complexity, they tend to have low i-complexity. They conclude that morphological paradigms have evolved under a pressure for low i-complexity, such that even paradigms with very high e-complexity are relatively easy to learn so long as they have low i-complexity. While this would potentially explain why languages are able to maintain large paradigms, recent work by Johnson et al. (submitted) suggests that both neural networks and human learners may actually be more sensitive to e-complexity than i-complexity. Here we will build on this work, reporting a series of experiments under more realistic learning conditions which confirm that indeed, across a range of paradigms that vary in either e- or i-complexity, neural networks (LSTMs) are sensitive to both, but show a larger effect of e-complexity (and other measures associated with size and diversity of forms). In human learners, we fail to find any effect of i-complexity at all. Further, analysis of a large number of randomly generated paradigms show that e- and i-complexity are negatively correlated: paradigms with high e-complexity necessarily show low i-complexity.These findings suggest that the observations made by Ackerman & Malouf (2013) for natural language paradigms may stem from the nature of these measures rather than learning pressures specially attuned to i-complexity.
The Mordovian Family of the Saratov Province of the Late XIX century according to the Data of Agricultural Censuses
Authors: Mel’nikov Pavel Ju.
Published: October 2021

Introduction. Second half of the 19th century for the Russian Empire is marked by the intensification of the process of transition from a traditional society to an industrial one. This transformation also affected such a conservative institution as the family. Its characteristic feature is the decrease in the average size of the family and the simplification of its structure. However, the transformation process was uneven, under the influence of regional characteristics, factors of the socio-economic and cultural type. Research Methods. The research was carried out on the basis of a comprehensive statistical analysis of the primary material of the zemstvo agricultural censuses located in the fund of the Provincial Statistical Committee of the State Archives of the Saratov Region. Results. The surviving materials include over 800 Mordovian households. The analysis of them allows us to speak about the predominance of this ethnos at the end of the 19th century a large, undivided family. This can be traced both in the total number of households of this type and in the number of people living in them. In the general base, the most populated households belonged to the Mordovians, the Tatar and Russian were smaller. Discussion and Conclusion. The article attempted to test the hypothesis that the family structure becomes more complex as it grows. It was found that a small family dominated in a group of households of up to 6 people, and a complex family dominated by 7 or more people. The extended type of household was not predominant in any group, occupying an intermediate position.

Abstract The objective of this study was to characterize the chemical composition in extracts of atemoya (var. Thompson) seed oil by spectrometric methods. The following extraction methods were performed: chemical extraction using hexane, mechanical extraction using a press, and partitioned extraction. The composition of each of the extracts was analysed by gas chromatography-mass spectrometry (GC-MS), and more than 100 compounds were identified. The major constituents of the hexane extraction were (Z)-hexadec-9-enal (49.42%) and triolein (23.28%), and the mechanically obtained extract contained elaidic acid (66.11%) and stearic acid (8.81%). In the partitioned extraction, the hydromethanolic fraction contained dihydroxyacetone (19.16%), 3-deoxy-d-mannoic lactone (16.34%), 5-hydroxymethylfurfural (10.77%), and 3-propanediol, 2-(hydroxymethyl)-2-nitro (9.89%); the hexane fraction contained gamma-sitosterol (31.73%), erucic acid (14.64%), stigmasterol (13.30%) and triolein (10.90%); the chloroform fraction contained gamma-sitosterol (22.11%), vaccenic acid (15.49%), triolein (14.65%) and stigmasterol (10.65%); and the ethyl acetate fraction contained (Z)-icos-9-enoic acid (31.28%), beta-sitosterol (16.29%), pentadecanoic acid (11.53%) and eicosanoic acid (8.01%).
CONHECIMENTO MORAL E VIRTUDES EPISTÊMICAS
Authors: Coitinho Denis
Published: October 2021

RESUMO O objetivo é refletir sobre o escopo do conhecimento moral a partir do modelo da ética das virtudes, que toma por base a ideia de caráter virtuoso e florescimento humano, sendo esta abordagem bastante promissora para responder ao argumento cético que diz que o desacordo moral é uma prova irrefutável da impossibilidade do conhecimento no campo da ética. Para este fim, inicio problematizando o conhecimento moral, com a consideração específica do raciocínio ético. Posteriormente, investigo o papel das virtudes epistêmicas de sabedoria prática, humildade e integridade para a aquisição do conhecimento moral. Por fim, postulo que a ética das virtudes, que conta com certas virtudes epistêmicas, pode explicar adequadamente o conhecimento moral e responder de forma mais eficiente ao ceticismo.
A ESTÉTICA FILOSÓFICA DE GIANNI VATTIMO
Authors: Miranda Luis Uribe
Published: October 2021

RESUMO Este texto tem como escopo mostrar a plausibilidade da tese de Gianni Vattimo, segundo a qual, a morte ou fim da arte, pensada pelo filósofo italiano como tramonto ou crepúsculo da arte, pode ser uma chance para pensar a estética filosófica na chamada condição pós-moderna. A plausibilidade dessa tese é mostrada por meio de um percurso estético-filosófico a partir das obras estéticas na língua original do autor, nas quais se evidenciam a constante dos conceitos de produção, ontologia, verdade e Verwindung com o intuito de mostrar a vocação ontológica da estética vattimiana. A pergunta que norteia as reflexões estéticas de Vattimo não tem por finalidade responder o que é a arte e, sim, qual o sentido de produzir obras artísticas na época do fim da arte. Lidas nessa perspectiva, as obras estéticas de Vattimo mostram a necessidade de iniciar toda e cada estética filosófica da aceitação do pressuposto da historicidade da arte e da necessária experiência artística porque nela, seguindo a filosofia de Heidegger, acontece a arte como posta em obra da verdade.

Resumo Este estudo centra-se na análise das condições sobre as quais trabalhadores brasileiros têm sido identificados como sobreeducados em seus primeiros empregos, bem como na probabilidade de permanecerem com esse status nos anos de 2006 e 2015. Busca-se também investigar os diferenciais de efeitos entre trabalhadores inicialmente sobreeducados, mas que foram primeiramente engajados em empresas com capacidade produtivas diferenciadas. São considerados sobreeducados os trabalhadores que desempenham funções que exigem abaixo de seu nível de escolaridade. Informações provenientes da Relação Anual de Informações Sociais (RAIS) e da Classificação Brasileira das Ocupações (CBO) de 2002 alimentaram um modelo probit bivariado recursivo que permitiu a realização empírica do estudo. Os resultados mostram que o status de sobreeducação no primeiro emprego em 2006 aumenta em 43,6% a probabilidade de o trabalhador repetir a mesma incompatibilidade no emprego em 2015. Além disso, trabalhadores sobreeducados aceleram suas transições para empregos condizentes ao engajarem o primeiro emprego em empresas de grande porte.

Com base nas Pesquisas de Orçamentos Familiares de 1996, 2003, 2009 e 2018 do IBGE, aplica-se o modelo Country Product Dummy para estimar os custos comparativos, o que permite avaliar a paridade do poder de compra dessas áreas. As famílias foram alocadas a oito classes de renda, trabalhando-se com uma família representativa em cada classe e região. Foram montadas séries para o índice geral e para seis grupos de bens e serviços para o período 1996-2020, que são disponibilizadas para uso dos pesquisadores. Houve mudanças interessantes no período, tanto nas estruturas de consumo como no índice comparativo de custo de vida.

Published: October 2021

Resumo Assumindo a forma de um ensaio biográfico, este artigo aborda o problema do translinguismo do ponto de vista da tradução de poesia em sentido invertido, da autotradução e da criação poética. Partindo de narrativas em primeira pessoa sobre experiências translíngues, visa interrogar também a voz que reúne pensamentos e vivências sob a égide discursiva do “eu” em suas relações e tensões com a pluralidade linguística. Para isto, mobiliza outras vozes, em diálogos com Sylvia Molloy, Etel Adnan, Jacques Derrida. Discute também com as teorias da tradução de Paul Ricœur, Haroldo de Campos e Walter Benjamin.

Abstract: Managers of organizations have few tools to evaluate manufacturing capabilities. Such scarcity implies in a greater difficulty to generate or maintain sustainable competitive advantages over competitors. This study aims to replicate the instrument developed by Jain et al. (2014) for the evaluation of manufacturing capabilities and analyze the results in the Brazilian business and cultural contexts. The instrument was translated into Portuguese using back-translation. After this, was performed a pre-test to verify understanding and clarity, then the instrument was distributed electronically. For data analysis, reliability analysis, face validation method, content validation, multiple regression analysis and factor analysis were performed. Subsequently, the results were compared with those of the work by Jain et al. (2014). Additionally, an exploratory factor analysis was performed to verify the convergent validity of the work. Statistical results were not adequate to validate the instrument in its current format, which requires improvements for it to be applied as a manufacturing capabilities assessment method in Brazil. The reliability index was adequate in approximately half of the instrument questions. As for multiple regression analysis, the results were not satisfactory. In addition, this research performed an exploratory factor analysis. Inconsistencies were identified. From ten expected factors, only four were obtained and had a low reliability index. These results contributed to the improvement of the instrument developed by Jain et al. (2014). It will be possible to take into account the results obtained in this study for implementations of statistical improvements and to observe questions that need to be changed in order to actually represent the 10 manufacturing decision areas of Hayes et al. (1988). Thus, it is necessary to conduct further studies and make improvements to make it a valuable tool for manufacturing.
CORPO E SINTOMA NO PACIENTE SOMATIZADOR: UMA VISÃO PSICODINÂMICA
Authors: MACÊDO KÁTIA BARBOSA
Published: October 2021

RESUMO: O texto aborda a concepção dual de corpo para a psicanálise, resultante do processo de constituição do psiquismo, que inicia na sensação, passando pela memória e chegando na representação e simbolização. Em seguida, discute o conceito de sintoma, apresentando breve percurso nas principais escolas psicossomáticas, visando trazer a divergência em relação ao sintoma carregar ou não um sentido. Apesar das controvérsias e divergências para atendimento a pacientes somatizadores, há concordância em relação a algumas características dos pacientes somatizadores: dissociação afetiva; dificuldade de simbolização e no estabelecimento de vínculos afetivos. O manejo clínico desses pacientes requer ajustes, o analista deve constituir um vínculo transferencial que possibilite a tradução ou nomeação do inominável, sua interpretação e ressignificação para integração na psiquê.
Sobre o colapso da objetalidade no discurso do capitalista

RESUMO: O artigo refaz o percurso de Freud desde a exclusão de das Ding até o surgimento da dimensão da objetalidade por meio da constituição da realidade estruturada como fantasia. Com Lacan, coloca-se em evidência o objeto a como causa do desejo no Seminário da Angústia, no qual se discute a caducidade dos objetos que estabelecem bordas pelas quais a libido irá se deslocar em busca do objeto perdido. Enfim, aborda-se o colapso da objetalidade na vigência do discurso do capitalista. Em particular, é sublinhado o engodo desse discurso que faz supor acessível o objeto perdido na forma dos gadgets que a cada vez renovam a promessa de mais gozar.
PAULO FREIRE NA UNICAMP: O RANÇO AUTORITÁRIO E O VERNIZ DEMOCRÁTICO
Authors: Mazza Débora
Published: October 2021

RESUMO O artigo analisa a passagem de Paulo Freire pela Unicamp. Autores apontam que a institucionalização das universidades é marcada por movimentos tanto de cultivo da autonomia didática, política, administrativa e financeira, quanto de recrudescimento de protocolos burocráticos e fortalecimento de corporativismos que emperram fluxos de inovação, mudanças e percursos plurais. Ancorado nos documentos do Processo de Vida Funcional de Paulo Freire na Unicamp, sugere que seu percurso pode ser tomado como um caso paradigmático de compreensão de projetos institucionais em disputa, os quais indicam interesses que oscilam entre perspectivas crítica, popular e democrática e ações que priorizam a tradição, os ritos burocráticos e um percurso modelar de construção de carreiras no magistério superior.

ABSTRACT BACKGROUND: Percutaneous endoscopic gastrostomy (PEG) is an important option for enteral nutrition for both children and adults. It is considered a safe, effective, and advantageous technique in comparison to other complementary feeding routes. It allows continuous feeding, the feeding of patients with swallowing disorders due to neurological causes or others, and the administration of non-palatable diets or medications, all with low rates of complications and mortality. OBJECTIVE: This study aimed to evaluate the main indications and complications of PEG in pediatric patients. In addition, the impact on the nutritional status of patients undergoing PEG was also compared with weight, body mass index (BMI), and height according to references from the World Health Organization. METHODS: This observational and retrospective study included 152 children and adolescents who underwent PEG between January/2003 and December/2018. Patients up to 18 years of age at the time of the procedure were included. Complications related to the procedure were classified as minor or major. Patients with PEG indication for nutritional supplementation were evaluated for weight gain, height, and BMI, using the Z score at the day of the procedure and six months, 1 year, and 2 years after the procedure. RESULTS: Indications for PEG were: swallowing disorder of neurological cause (67.1%), need for nutritional supplementation (25%), swallowing disorder of mechanical origin (6.6%), and indication of gastric decompression (1.3%). Minor complications occurred in 57.8% of patients and major complications in 9.8% of patients. The traction technique corresponded to 92.1% and puncture to 7.9%. The death rate was 1.3%. Thirty-eight patients had an indication for nutritional supplementation. In these patients, there was a gradual increase in both BMI and weight, reaching statistically significant differences (P=0.0340 and P= 0.0105, respectively). These differences were more evident in chronic renal disease patients. Height did not vary significantly (P=0.543). CONCLUSION: PEG proved to be an advantageous option as an auxiliary feeding method in pediatric patients. Dysphagia of neurological origin was the main indication followed by the need for nutritional supplementation. PEG has low frequency of major complications and mortality. This study also showed the importance of PEG in patients who need nutritional supplementation, as it enabled patients to move from undernutrition to normal weight ranges.

ABSTRACT BACKGROUND: The COVID-19 pandemic has changed digestive endoscopy services around the world. OBJECTIVE: This study aimed to measure the number of urgent/emergency endoscopic procedures performed in a Brazilian hospital, comparing it to the same period in the previous year, and to identify risk factors in COVID-19 patients undergoing endoscopic procedures for upper gastrointestinal bleeding (UGIB). METHODS: This was a retrospective, cross-sectional, observational, single-center study. The study evaluated urgent/emergency endoscopic procedures performed on adult patients from March to August in 2019 and 2020. The COVID-19 patients included were diagnosed using RT-PCR, aged over 18 years with complete medical record information. The variables evaluated were age, sex, comorbidities, length of stay, D-dimer, need for intensive care unit (ICU) and mechanical ventilation. Student’s t-test for independent samples or the non-parametric Mann-Whitney test was used to compare quantitative variables. Categorical variables were analyzed using Fisher’s exact test. A P-value <0.05 indicated statistical significance. RESULTS: A total of 130 urgent/emergency endoscopic procedures were performed in 2020 and 97 in 2019. During the study period, 631 patients were hospitalized due to COVID-19, of whom 16 underwent urgent/emergency endoscopic procedures, 10 (1.6%) due to UGIB. Of the variables analyzed, the need for ICU and/or mechanical ventilation during hospitalization was statistically significant as a risk factor for UGIB. CONCLUSION: This study showed increased urgent/emergency endoscopic procedures during the pandemic at the study site. Among the patients hospitalized with the novel coronavirus, there is a higher risk for UGIB in those needing ICU and/or mechanical ventilation.
