Authors: Tamauchi Satoshi , Moriyama Yoshinori , Suzuki Shiro , Ikeda Yoshiki , Yoshikawa Nobuhisa , Kajiyama Hiroaki
Published: August 2021

Cervical cancer is a human papilloma virus‐related disease, whereas endometrial cancer and atypical endometrial hyperplasia (AEH) are hormone‐related diseases, so co‐occurrence of the two is possible. However, scientific studies about such cases are rare. We encountered a case of cervical adenocarcinoma and AEH in a 33‐year‐old nulliparous woman. Two fertility‐sparing treatments were performed, a radical trachelectomy for the cervical cancer and high‐dose medroxyprogesterone acetate treatment for the AEH. After remission of the diseases, the patient became pregnant by in vitro fertilization and delivered a baby at 36 weeks' gestation by cesarean section. Although the patient had two uterine malignancies, proper evaluation of the diseases, consultation with the patient and her husband, and appropriate management led to fertility preservation, and live birth was achieved.
Current trends in electrophysiological research on bilingual language processing
Authors: Jankowiak Katarzyna
Published: August 2021

Recently, much psycholinguistic research has been devoted to examining cognitive mechanisms engaged in language processing in the bilingual context, as this might provide in‐depth insights into how different languages interact with one another as well as how and to what extent language competence affects cognition. At the same time, along with such a growing interest in studying bilingual populations, psycholinguistics as a discipline has been rapidly developing owing to the more and more widespread use of physiological research methods. Particularly, electroencephalography (EEG) has received much scholarly attention, as it can elucidate the exact time course of language processing. The present contribution explores current trends in EEG research on bilingual language processing and discusses how event‐related potential (ERP) studies and their findings have been extended from the monolingual to the bilingual context. To this end, the paper discusses selected ERP experiments into language co‐activation across different modalities, bilingual executive control, electrophysiological correlates of new meaning construction, neural changes accompanying foreign language learning, and the automaticity of emotional responding in bilingual speakers.
Mental health nursing and conscientious objection to forced pharmaceutical intervention
Authors: Gadsby Jonathan , McKeown Mick
Published: August 2021

This paper attempts a critical discussion of the possibilities for mental health nurses to claim a particular right of conscientious objection to their involvement in enforced pharmaceutical interventions. We nest this within a more general critique of perceived shortcomings of psychiatric services, and injustices therein. Our intention is to consider the philosophical and practical complexities of making demands for this conscientious objection before arriving at a speculative appraisal of the potential this may hold for broader aspirations for a transformed or alternative mental health care system, more grounded in consent than coercion. We consider a range of ethical and practical dimensions of how to realize this right to conscientious objection. We also rely upon an abolition democracy lens to move beyond individual ethical frameworks to consider a broader politics for framing these arguments.
Cat‐Calls, Compliments and Coercion

In this paper, I offer a novel argument for why cat‐calling is wrong. After warding off the objection that cat‐calls are compliments and therefore morally benign, I show that it cannot be the semantic content of cat‐calls which makes cat‐calling wrong, because some cat‐calls have seemingly benign content yet seem to wrong their targets (usually women and LGBTQ people) nonetheless. Instead, cat‐calling is wrong because itsilencestargets, by preventing them from blocking cat‐callers' presuppositions of authority, andexploitsthem, by forcing them into the demeaning position of acting as if they consider cat‐callers to have authority over them.
Eating disorders through the periodontal lens
Authors: Rangé Hélène , Colon Pierre , Godart Nathalie , Kapila Yvonne , Bouchard Philippe
Published: August 2021

People with eating disorders suffer from a mental disorder that negatively affects their physical and/or mental health. The three most frequent eating disorders are binge eating disorder, bulimia nervosa, and anorexia nervosa. Environmental and genetic factors are involved in the pathogenesis of eating disorders in vulnerable persons. Although treatment varies among different types of eating disorders, nutrition, medical care combined with psychotherapy and medications are standard of care. The aim of this review is to give an overview of the oral health impact of eating disorders with a special emphasis on the periodontium. Oral health professionals have a unique role to play in the early diagnosis of eating disorders because of the important impact that eating disorders have on the oral cavity. In vomiting‐associated eating disorders, the risk of erosive tooth wear is mainly localized to the palatal surfaces of the incisors. Emerging evidence also indicates a high frequency of gingivitis and gingival recessions associated with compulsive toothbrushing. A holistic approach, including oral health and functional rehabilitation, should be promoted by physicians, psychiatrists, and dentists for people with eating disorders.

Published: August 2021

In view of the pressing need for alternative clean energy source to displace the current dependence on fossil fuel, proton exchange membrane fuel cell (PEMFC) technology have received renewed research and development interest in the past decade. The electrolyte, which is the proton exchange membrane, is a critical component of the PEMFC and is specifically targeted for research efforts because of its high commercial cost that effectively hindered the widespread usage and competitiveness of the PEMFC technology. Much effort has been focused over the last five years towards the development of novel, durable, highly effective, commercially viable, and low-cost co-polymers as alternative for the expensive Nafion® proton exchange membrane, which is the current industry standard. Our primary review efforts will be directed upon the reported researches of alternative proton exchange membrane co-polymers which involved Triptycene derivatives. Triptycene derivatives, which contain three benzene rings in a three-dimensional non-compliant paddlewheel configuration, are attractive building blocks for the synthesis of proton exchange membranes because it increases the free volume in the polymer. The co-polymers considered in this review are based on hydrocarbon molecular structure, with Triptycene involved as a performance enhancer. Detailed herein are the development and current state of these co-polymers and their performance as alternative fuel cell electrolyte.

Published: August 2021

The detectability of fibrils in mammographic phantom images by morphological enhancement was analysed in the present study. Materials that mimic fibrils were imaged by a digital mammography machine at 28 and 29 kVP. The images were processed by a dilation technique to produce second set of images. Receiver operating characteristic analysis was performed to compare the detection performance from the two sets of images. As compared to original images, the 28 kVP’s fibrils images from dilation technique become more prominence to be detected by observers. While at 29 kVP only a few observers can found the fibrils images from dilation technique. This study suggests morphological enhancement of mammography image did not increase the detection of low frequency signals of the images.
Herschel-Bulkley Model of Blood Flow through a Stenosed Artery with the Effect of Chemical Reaction on Solute Dispersion
Authors: Mohd Zainul Abidin Siti Nurul Aifa , Jaafar Nurul Aini , Ismail Zuhaila
Published: August 2021

A non-Newtonian mathematical model of blood described as a Hershel-Bulkley fluid model flowing in a stenosed artery with the effect of a chemical reaction is mathematically studied. The expressions of the shear stress, mean velocity and absolute velocity in the plug and non-plug flow field are evaluated analytically. The convective-diffusion equation is solved using the Taylor-Aris technique subject to the relevant boundary constraint in determining the concentration, relative and effective axial diffusivity. The efficiency of the dispersion process is affected by the presence of chemical reaction and stenosis in blood flow. The normalized velocity decreases as stenosis height and stenosis length increase. The relative axial diffusivity is significantly lower while the effective axial diffusivity decreases considerably as the chemical reaction rate, the height of the stenosis and the length of the stenosis increase. Besides, it is observed that as the solute disperses in the presence of stenosis, the flow quantities are lesser than in the absence of stenosis. Further, this study helps in understanding many physiological processes for instance dispersion of drugs or nutrients in the circulatory system. Also, to enhance the dispersion of a solute in blood flow through narrow arteries in the presence of chemical reaction and stenosis.
La televisión presidencialista en Colombia, 1954-1974
Authors: Arizmendi Correa José Vicente
Published: August 2021

Durante más de treinta años, la televisión colombiana padeció unos defectos de nacimiento y mala crianza que le impidieron desarrollarse y la convirtieron en un monstruo pesado y encerrado en sí mismo, centralista, inseguro y anticuado. A Colombia llegaron tarde la conexión a los satélites, las grabadoras de video, la televisión en color, los canales regionales y la libertad creativa para los generadores de contenidos. Por razones políticas, el país apostó infructuosamente a una fallida televisión educativa y cultural, un proyecto idealista e ingenuo que habría requerido cuantiosas fuentes de financiación con las que no se contaba. Los funcionarios gubernamentales tenían capacidad de escoger el tipo de telenovelas que debían producirse y hasta el estilo de las series estadounidenses que debían programarse. El origen de estos y otros males fue la relación malsana que se estableció desde un comienzo entre el medio y la Presidencia de la República. La televisión tardó más de tres décadas en cortar ese cordón umbilical que la ataba con el Poder Ejecutivo, una tara que surgió desde el momento en que aparecieron en pantalla las primeras imágenes.
A Surface Energy Approach to Developing an Analytical Model for the Underfill Flow Process in Flip-Chip Packaging
Authors: Yao Xingjun , Jiang Weijie , Yang Jiahui , Fang Junjie , Zhang Wenjun
Published: August 2021

This paper presents a new approach to formulating an analytical model for the underfill process in flip-chip packaging to predict the flow front and the filling time. The new approach is based on the concept of surface energy along with the energy conservation principle. This approach avoids the need of modeling the flow path to predict the flow front and the filling time, and thus it is suitable to different configurations of solder bumps, including different shapes and arrangements of solder bumps in flip-chip packaging. An experiment along with the computational fluid dynamics simulation was performed based on a proprietarily developed testbed to verify the effectiveness of this approach. Both the experimental and simulation results show that the proposed approach along with its model is accurate for flip-chip packages with different configurations besides the configuration of a regular triangle arrangement of solder bumps and a spherical shape of the solder bump.

Classification of quantum states based on the null energy condition
Authors: Mandal Susobhan
Published: August 2021

Violation of the null energy condition plays an important role both in the general theory of relativity and quantum field theory in curved spacetimes. Over the years, it has been shown that the violation of the null energy condition leads to instability and violation of causality. In quantum field theory, violation of the energy condition also depends on the quantum states apart from the geometry of curved spacetime. Hence, the quantum effects play an important role in the violation of the null energy condition. We show that the set of all the coherent states does not violate the null energy condition. Further, we also show that under certain conditions, the null energy condition is violated either by a pure state or a mixed state. Furthermore, the dynamical violation of the null energy condition by the quantum states is also discussed here.

On the structure of symmetric n-ary bands
Authors: Devillet Jimmy , Mathonet Pierre
Published: August 2021

We study the class of symmetric [Formula: see text]-ary bands. These are [Formula: see text]-ary semigroups [Formula: see text] such that [Formula: see text] is invariant under the action of permutations and idempotent, i.e., satisfies [Formula: see text] for all [Formula: see text]. We first provide a structure theorem for these symmetric [Formula: see text]-ary bands that extends the classical (strong) semilattice decomposition of certain classes of bands. We introduce the concept of strong [Formula: see text]-ary semilattice of [Formula: see text]-ary semigroups and we show that the symmetric [Formula: see text]-ary bands are exactly the strong [Formula: see text]-ary semilattices of [Formula: see text]-ary extensions of Abelian groups whose exponents divide [Formula: see text]. Finally, we use the structure theorem to obtain necessary and sufficient conditions for a symmetric [Formula: see text]-ary band to be reducible to a semigroup.
Theoretic Model of Adversaries and Media Manipulation: A Two-Period Extension
Authors: Hausken Kjell
Published: August 2021

Two adversarial actors interact controversially. Early incomplete evidence emerges about which actor is at fault. In period 1 of a two-period game, two media organizations identify ideologically with each of the two actors who are the players exerting manipulation efforts to support the actor they represent. In period 2, the full evidence emerges. Again, the two players exert efforts to support their preferred actor. This paper illustrates the players’ strategic dilemmas for the typical event that actor 1 is considerably at fault based on the early evidence, and much less at fault based on the full evidence. The model assumes that exerting effort in period 1 implies reward or punishment in period 2 depending on whether the full evidence exceeds the early evidence. Twelve parameters in the model are varied individually relative to a benchmark. For example, the players’ efforts are inverse U shaped to an extent in which the actors they identify with are at fault in the two periods. Increasing the evidence ratio intensity causes lower efforts since the players become more unequally matched.

Authors: Verma Pratibha , Kumar Manoj , Shukla Anand
Published: August 2021

This article introduces the computational analytical approach to solve the m-dimensional space-time variable Caputo fractional order advection–dispersion equation with the Dirichlet boundary using the two-step Adomian decomposition method and obtain the exact solution in just one iteration. Moreover, with the help of fixed point theory, we study the existence and uniqueness conditions for the positive solution and prove some new results. Also, obtain the Ulam–Hyers stabilities for the proposed problem. Two generalized examples are considered to show the method’s applicability and compared with other existing numerical methods. The present method performs exceptionally well in terms of efficiency and simplicity. Further, we solved both examples using the two most well-known numerical methods and compared them with the TSADM solution.
DenseNet-Based Classification of MRI Images for Detecting the Difference before and after Treating Liver Cancer
Authors: Peng Jianbo
Published: August 2021

This study aimed to explore the evaluation of Adriamycin-loaded microspheres in the treatment of liver cancer under DenseNet-based magnetic resonance imaging (MRI) image classification algorithm. According to different treatment methods, the research objects were classified into a normal saline (saline) group, a doxorubicin raw material (DOX) group, and a chitosan cross-linked pectin-doxorubicin conjugate macromolecular (CS-PDC-M) group. DenseNet’s migration learning was employed to analyze the dynamic enhanced MRI characteristics and classify the MRI images. The CS-PDC-M-targeted nanotransfer system was examined with its apparent morphology, drug absorption, and cytotoxicity. Tumor volume was monitored using MRI, and alanine aminotransferase (ALT) and creatine kinase isoenzyme (CK-MB) values were detected. Results showed that the classification accuracy of liver cancer MRI image based on DenseNet model reached 80% at the arterial hepatobiliary stage. The DOX and CS-PDC-M group had obviously smaller tumor volume than that of the saline group

. Therefore, DOX had an inhibitory effect on tumor but damaged the heart and liver. DOX was used to construct CS-PDC-M that could maintain the original treatment effect of DOX and inhibit its side effects on the body, so CS-PDC-M had a clinical application value. In conclusion, Adriamycin-loaded microspheres could not only maintain the original therapeutic effect of Adriamycin but also inhibit its toxic and side effects on the body. The  DenseNet model was applied in the liver cancer MRI dynamic image classification algorithm, and the normalization algorithm could improve the accuracy of the liver cancer microvessel classification, thus promoting the diagnostic efficiency of liver cancer diagnosis, which had clinical application value.
Effect of Biochar and Inorganic Fertilizer on the Soil Properties and Growth and Yield of Onion (Allium cepa) in Tropical Ethiopia
Authors: Aneseyee Abreham Berta , Wolde Tekilil
Published: August 2021

Biochar is a carbon-rich product, which is processed by pyrolyzing biomass to improve soil properties and maintain environmental sustainability. This study aim was to investigate the effect of biochar and inorganic fertilizer on soil properties, growth, and yield. Four treatments and four replications have been used for the experimental plots using Randomized Complete Block Design (RCBD). Soil physiochemical properties have been investigated based on soil samples within 0–30 cm depth in each plot. The two types of biochar (grass and chat waste) have been used for the treatments. The pyrolyzing temperature required for grass and chat waste is 250°C and 1100°C, respectively. The plant height, total yield, and the marketable and nonmarketable yield of onion have been examined. The analysis showed that treatment with grass biochar and inorganic fertilizer had a similar effect on soil properties but chat (Catha edulis) biochar had a lower effect on soil properties. The total yield and days to 70% maturity have been increased due to the cumulative treatment of grass biochar and inorganic fertilizer. The biochar of grass and inorganic fertilizer have been significantly increased in marketable bulb yield, but unmarketable yield becomes decreased. The chat waste and controlled treatments shown an increased unmarketable yield and declined marketable bulb yield. Overall, biochar can substitute the inorganic fertilizer, which can help to improve thewsoil fertility and environmental sustainability. Therefore, biochar has a win-win solution.
Important Issues on Spectral Properties of a Transmission Eigenvalue Problem

Published: August 2021

Nowadays, inverse scattering is an important field of interest for many mathematicians who deal with partial differential equations theory, and the research in inverse scattering is in continuous progress. There are many problems related to scattering by an inhomogeneous media. Here, we study the transmission eigenvalue problem corresponding to a new scattering problem, where boundary conditions differ from any other interior problem studied previously. more specifically, instead of prescribing the difference Cauchy data on the boundary which is the classical form of the problem, we consider the case when the difference of the trace of the fields is proportional to the normal derivative of the field. Typical concerns related to TEP (transmission eigenvalue problem) are Fredholm property and solvability, the discreteness of the transmission eigenvalues, and their existence. In this article, we provide answers for all these concerns in a given interior transmission problem for an inhomogeneous media. We use the variational method and a very important theorem on the existence of transmission eigenvalues to arrive at the conclusion of the existence of the transmission eigenvalues.
The Spatial Agglomeration and Industrial Network of Strategic Emerging Industries and Their Impact on Urban Growth in Mainland China
Authors: Li Jiaming , Zhang Peiyuan , He Jialin , Sun Dongqi
Published: August 2021

Strategic emerging industries (SEIs) are an important industrial policy to promote innovation, develop advanced manufacturing, and upgrade the economy in China. The research explores the impact of SEIs on urban economic growth in mainland China, from agglomeration externalities and network externalities. The results show that SEIs have a significant impact on growth, and network externalities are generally more important than agglomeration externalities. Although the agglomeration of large‐scale listed enterprises in the city promotes growth, too many large enterprises in the cluster, that is, the lack of small and medium‐sized supporting enterprises, will harm urban growth. Meanwhile, a city with a higher degree of centrality has a larger GDP, but the strength has a negative impact.
[Retracted] Comparative Analysis of Natural Fibre Reinforced Composite Material Using ANSYS
Authors: Saravanan K. G. , Prabu R. , Sivapragasam A. , Daniel Nahom
Published: August 2021

The regulations of legislative bodies regarding the recycling and reusage of automotive materials has caused a great deal of obligation among automotive manufacturers to use natural fibres or green composites. Green composites or more commonly known as bio‐composites are made up of natural fibres. Natural fibres are used by humankind since prehistoric times. The natural fibre is obtained from plants as well as animals. Since the natural fibre is obtained from natural as well as biological resources, it is biodegradable and recyclable. This paper presents the study and analysis conducted to address the suitability of natural fibre in the automotive industry. This paper discusses the finite element analysis of four different natural fibre composites used for making car door panel, i.e., flax, jute, sisal, and leather are taken for the material study. This paper helps to find the effectiveness of each of the four natural fibre composites that have already been used in the automotive sector. This paper includes the analysis of four different natural fibres with and without the addition of the aluminium as the reinforcement material. This project revolves around the design of the composite fibre sheet and analysis of the mechanical parameters such as equivalent stress, shear stress, strain, deformation, and so on. The studies and observations of the analysis showed that the natural fibre with the aluminium reinforcement proved to be much stronger than that without the reinforcement. The results of finite element analysis showcased lowest total deformation and equivalent strain in the flax as 1.026 m and 0.017 mm/mm, respectively. However, sisal showed the lowest equivalent stress and shear stress which were 68.09 and 38.178 MPa, respectively. Additionally, leather showed the highest amount of stress, strain, and deformation, and hence leather was deemed to have undesirable properties regarding the usage in car door panels. All the materials except leather were found to be safe under the loading conditions. Hence, the flax fibre is recommended by the project to have superior properties compared to the other materials.

The automobile instrument is the indispensable item that is essential to keep the driver conversant of the process of the engineer and the other system. There are different parameters involved in the automobile instrument, which requires a different process involved in creating the automobile parameter. This research is designed to show the simulation development of injection molding and optimization of automobile instrument parameters using different optimization techniques. In this paper, Taguchi Orthogonal parameter design and particle swarm optimization (PSO) are used to measure the shrinkage volume rate and warpage amount rate. Most of the studies are designed to calculate the reduction and warpage for the gate location and glass material. The Taguchi orthogonal design contains five different parameters which are inversely proportional to each other. Hence, by optimizing those parameters, the injection molding procedure is passed out. In this research, the paper is designed to process the injection molding for the automobile instrument parameter using optimization techniques.

Published: August 2021

Introduction: The development of a family history (FH) questionnaire (FHQ) provides an insight into a patient’s familiarity of a trait and helps to identify individuals at increased risk of disease. A critical aspect of developing a new tool is exploring users’ experience. Objective: The objective of this study was to examine users’ experience, obstacles and challenges, and their views and concerns in the applicability of a new tool for determining genetic risk in Slovenia’s primary care. Methods: We used a qualitative approach. The participants completed a risk assessment software questionnaire that calculates users’ likelihood of developing familial diseases. Audio-taped semi-structured telephone interviews were conducted to evaluate their experience. There were 21 participants, and analyses using the constant comparative method were employed. Results: We identified 3 main themes: obstacles/key issues, suggestions for improvements, and coping. The participants were poorly satisfied with the clarity of instructions, technical usability problems, and issues with the entry of relatives’ data. They expressed satisfaction with some of the characteristics of the FHQ (e.g., straightforward and friendly format, easy entry, and comprehension). They suggested simpler language, that the disease risk should be targeted toward the disease, that the FHQ should include patient-specific recommendations, and that it should be part of the electronic medical records. When discussing what would they do with the results of the FHQ, the participants used different coping strategies: active (e.g., seeking information) or passive (e.g., avoidance). Discussion/Conclusion: User experience was shown to be a synthesis of obstacles, overcoming them with suggestions for improvements, and exploration of various coping mechanisms that may emerge from dealing with the stressor of “being at risk.”

Introduction: Isolated ultrafiltration (IUF) is an alternative treatment for diuretic-resistant patients with fluid retention. Although hemodialysis (HD) predominantly decreases extracellular water (ECW), the impact of IUF on fluid distribution compared with HD remains unclear. Methods: We compared the effect of HD (n = 22) and IUF (n = 10) sessions on the body fluid status using a bioimpedance analysis device (InBody S10). Results: The total ultrafiltration volume was similar between HD and IUF (HD 2.5 ± 0.3 vs. ICF 2.1 ± 0.3 L/session, p = 0.196). The reduction rate of ECW was significantly higher than that of intracellular water (ICW) after HD (ECW −7.9% ± 0.8% vs. ICW −3.0% ± 0.9%, p < 0.001) and IUF (ECW −5.8% ± 0.9% vs. ICW -3.6% ± 0.8%, p = 0.048). However, the change in the ratio of ECW to total body water in HD was significantly larger than that in IUF (HD −3.2% ± 0.3% vs. ICF −1.1% ± 0.4%, p < 0.001). The reduction rates in serum tonicity (effective osmolality) were higher after HD than after IUF (HD −1.8% ± 0.5% vs. IUF −0.6% ± 0.2%, p = 0.052). Among the components of effective osmolality, the reduction rates of serum K+ and glucose levels after HD were significantly higher than those after IUF (serum K+: HD −30.5% ± 1.6% vs. IUF −0.5% ± 3.8%, p < 0.001; serum glucose: HD −15.4% ± 5.0% vs. IUF 0.7% ± 4.8%, p = 0.026), while the serum Na+ level was slightly and similarly reduced (HD −0.8% ± 0.4% vs. IUF −0.8% ± 0.4%, p = 0.500). The reduction in the osmolal gap value (measured osmolality–calculated osmolarity) was significantly greater after HD sessions than after IUF sessions (HD −12.4 ± 1.4 vs. IUF 2.0 ± 1.0 mOsm/kg, p = 0.001). Conclusion: The extracellular fluid reduction effect of HD is stronger than that of IUF. The different changes in effective osmolality and osmolal gap after HD and IUF sessions may be related to the different effects of HD and IUF on fluid distribution.
Labor and informal work in North-South relations: a study on Iberian countries and Latin-America
Authors: Estanque Elísio , Climent Víctor F.
Published: August 2021

Departing from the North/South dialogue, and considering the historical relations between the Iberian countries and Latin America (LA), the aim is to analyze trends, contrasts and asymmetries in different scales. Asymmetric powers and dynamic tensions and negotiations are discussed both in the world-system scale and in the European Union context. In the light of recent transformations in international capitalism, our paper addresses, on the one hand, the phenomenon of informality/labor precariousness and, on the other, resorting to a more prospective record, diagnoses some of the recent challenges of technological innovation and digitalization. Considering an ongoing project related to these issues (Latwork), our analysis encompasses the sociological knowledge developed by diverse research teams on the labor field, namely regarding informality and technological innovation. For this purpose, we also gather quantitative data on research teams from the universities of la countries (Brazil, Argentine and Chile) using factorial analysis. The aim is to foster decent work, particularly in the Latin American countries under study, where, as we know, the scourge of informality and vulnerability of the working classes is a structural feature that remains from colonial heritage till the early peripheral industrialization. Thus, the spirit of our study lies in the effort to understand the changes taking place in the field of labor relations at a time when global capitalism is at a crossroads in the face of the brutal impacts of the Covid-19 pandemic.
Impasses de formação: pensamento conservador em Schwarz e Freire
Authors: Gomes Carneiro Silvio Ricardo
Published: August 2021

O artigo pretende descrever a gênese do pensamento conservador como fenômeno da formação. Para tanto, considera a crítica literária e a educação como fontes importantes de descrição do sistema de formação nacional. Assim, apresenta a análise do pensamento conservador no ensaio “As ideias fora do lugar” de Roberto Schwarz. O ensaísta reflete aqui a gênese do conservadorismo nacional na figura dos homens livres, fundamentais na obra de Machado de Assis. Trata-se da submissão à ordem dos favores e da composição social dos agregados sob o olhar das elites dominantes. De maneira complementar, a pedagogia de Paulo Freire também ressalta a figura do pensamento conservador, mas do ponto de vista da condição do oprimido. É a partir do momento em que as contradições possibilitam a emersão para a consciência crítica que também opera com mais força o fanatismo apoiado no silenciamento e na violência do conservadorismo. Portanto, tanto sob o olhar do senhor, quanto da massa dos oprimidos, o pensamento conservador é resposta a impasses de formação. Seguimos, ao fim, com a pergunta: como intervir a partir do diagnóstico estético-político e pedagógico descritos, respectivamente, por Schwarz e Freire?
Notas sobre o direito de resistência no segundo tratado sobre o governo de John Locke
Authors: Tsuji Alessandra
Published: August 2021

O presente artigo busca examinar o capítulo XIX do Segundo Tratado, no qual Locke concentra seus argumentos em favor do direito de resistência. Nesse percurso, ressaltam-se alguns pontos fundamentais para a demonstração de que o exercício do poder sem autoridade, que implicana perda de confiança dos governados em relação ao governante e na própria dissolução do governo, dá início ao direito do povo de resistir. Dessa maneira, busca-se compreender como a autoridade pode retornar legalmente aos súditos para que possam, por meio de uma revolução,exercer o poder supremo para agir conforme sua vontade, restabelecer o legislativo anterior ou até mesmo instituir um novo.
La apropiación de los saberes tradicionales en México: una perspectiva semiótico-pragmática

Published: August 2021

El conocimiento de la medicina tradicional en México es un elemento distintivo de la diversidad cultural de este país. Por su larga existencia y convencionalidad, forma parte de los símbolos característicos de las culturas que lo desarrollaron y utilizaron de generación en generación. Sin embargo, hoy en día es objeto de apropiación legal por parte de agentes que buscan sacar beneficio de él y de otros elementos de las culturas indígenas. Esta apropiación es posible gracias al proceso de traducción y transmutación de los símbolos y a las transformaciones de las creencias a través del método abductivo, según la propuesta semiótico-pragmática de Charles Peirce. En este artículo, argumentamos que en dicha apropiación político-económica del conocimiento tradicional por parte de agentes no indígenas subyace una apropiación simbólica.
Culture and politics of laziness, from fairy tales to Oblomov and Bartleby
Authors: Marrone Gianfranco
Published: August 2021

The thesis of this paper is that laziness is not a psychological property of an individual subject but a collective sentiment: it is a reaction, or perhaps even a rebellion, against those who lock us within a culture that sees activity as a supreme value, often as an end in itself. Laziness is the response to those who force us to do and overdo, to give ourselves over to our occupations with zeal and constancy, total dedication and blind perseverance. So, it is not true that a lazy person does nothing, rather they do everything they can in order to not do anything. They work frantically in order to create the perfect conditions that allow them to activate their inertia. This paper tries to prove this thesis by analyzing some exemplary texts such as Goncharov's Oblomov, and linking it, upstream, with traditional Russian fairy tales and, downstream, with Melville Bartleby's famous tale.

Sobre técnicas e tecnologia: Uma perspectiva feminista dos estudos de artefatos líticos
Authors: Vieira Danusa
Published: August 2021

Reflexões teóricas substanciais foram feitas sobre a tecnologia enquanto meio de ação no mundo físico, social e culturalmente constituído, incluindo considerações que relevam do aspecto material, e não apenas simbólico, da produção social das técnicas, dentre elas, invenções que são consideradas cruciais para a evolução da humanidade. Artefatos de pedra lascada se encontram nessa categoria fundamental, tendo se constituído enquanto produção técnica intencional especificamente humana. Usualmente na disciplina arqueológica, artefatos líticos tendem a ser analisados de uma maneira clínica, segundo critérios que os permitem serem encaixados em esquemas tipológicos. Tal metodologia está intrinsecamente relacionada ao conceito moderno de tecnologia que se caracteriza por sua separação em relação à esfera das relações sociais e da cultura. Ainda que nos últimos anos tenha se construído uma crítica à divisão cartesiana entre sujeito/objeto e as limitações que tal abordagem apresenta para a construção do conhecimento científico, as normas de validade para estudos tecnológicos pressupõem ao menos algum aspecto tecno-tipológico incorporado à análise. A partir de uma perspectiva feminista dos estudos tecnológicos, reinserindo o campo das técnicas no conjunto das práticas sociais, pretendemos levantar questões de como seria possível analisar artefatos líticos a partir de outras concepções de tecnologia.
Falsificações arqueológicas na Turquia

Published: August 2021

Este artigo discute a autenticidade arqueológica na Turquia dos pontos de vista científico-acadêmico e popular. Na Turquia, “falsificações arqueológicas” que um dia receberam pouca atenção tem criado debates públicos nos últimos cinco anos. Apesar de já conhecido, o problema não era abordado de forma constante em pesquisas científicas. É provável que ainda tenhamos um longo caminho até que os arqueólogos turcos sejam capazes de lidar com este assunto em termos científicos e aceitá-lo como um importante campo de estudos. Embora a Turquia seja um país-chave tanto para a descoberta de originais quanto para a produção de falsificações, sabemos pouco sobre quais materiais devem ser categorizados como réplicas ou falsificações, quais objetos foram classificados, quais materiais foram falsificados, por que e por quem. Estima-se que o número de falsificações expostas em museus locais seja muito alto, incluindo inúmeras lamparinas, moedas, objetos metálicos (especialmente de prata) e pedras preciosas. Nos mercados internacionais conhecemos vários tipos de objetos que foram falsificados na Turquia, uma vez que é particularmente difícil distinguir entre moedas autênticas ou falsificações modernas, por exemplo. Diversos escândalos de falsificação em museus turcos surgiram nos últimos dez anos. Há duas explicações para os enganos: os administradores do museu não sabem nada sobre as falsificações, ou há outras razões pelas quais tais itens são apresentados como reais em exposições. Este artigo acompanha um catálogo amostral para a reanálise dos artefatos utilizando múltiplos critérios para a determinação de sua não autenticidade.
Prenatal care of Venezuelans in Colombia: migrants navigating the healthcare system

OBJECTIVES To explore the experiences of irregular (undocumented) Venezuelan migrants in accessing prenatal health services in Colombia and to examine the economic, social, and cultural resources mobilized by them to gain access to care. METHODS Data was retrieved from the qualitative component of a multi-method research conducted with pregnant immigrants in Barranquilla, Colombia, between 2018 and 2019, and triangulated with a review of regulations established by the Ministry of Health and Social Protection. RESULTS Having limited economic capital, participants use social capital from personal networks and migrant organizations. They obtain cultural health capital in the form of information on the health system and use their cultural competencies to interact with this system. CONCLUSIONS Migrants exert their agency through the use of capitals, although with certain constraints. Policies aimed at this social group should consider the strengths of migrants.
Looking back at the latest 20 years

Twenty years ago the International Palaeoentomological Society was founded in Kraków during the 2nd Congress on Palaeoentomology (5th–9th September, 2001). This congress was preceded by a world conference in Moscow, 1998 (which was afterwards given the formal numbering as first), and World Congress on Amber Inclusions in Vitoria-Gasteiz, Basque Country, Spain, 1998. Later, Brazilian Symposium on Palaeoarthropodology in Ribeirão Preto, Brazil held for the first time in 2000, took place. The event in Kraków attracted a record number of 120 participants. We were quite aware that this frequency in 2001 was partially caused by the curiosity of the country which for long time was behind the iron curtain. Literally most of the countries were represented; from USA to China, from Russia to South Africa, as you may notice from the list of 53 founding members, below, who also provided the starting Society with first donations.
Fossil insects 10 years after the Geological Conservation Review (Great Britain)
Authors: JARZEMBOWSKI ED
Published: August 2021

At the third congress of the I.P.S. (International Palaeoentomological Society) in Beijing (2010), Professor Dong Ren, conference organiser, was presented with an author’s copy of the arthropod volume of the Geological Conservation Review of Great Britain, which included fossil insects, and had just been published (Jarzembowski et al., 2010). The purpose of the review, which commenced in the last century before the founding of I.P.S., was essentially to select and document the key sites of British geology, geomorphology and palaeontology with view to geoheritage conservation—including palaeoentomology. The results were collated and published in a series of volumes and, as it subsequently transpired, the arthropod volume was the last one (number 35). The insect part (written by the current author) and other arthropods (by Derek Siveter and Paul Selden) were augmented by general geology and palaeontology contributed by Douglas Palmer. A planned volume with relevant Lower Cretaceous (Wealden) geology was eventually produced instead as a short series of papers by the Geologists’ Association of London (Radley & Allen, 2012b). Geoconservation has featured periodically on the I.P.S. agenda and this paper reflects on the legacy of the GCR study, a decade later, and over a generation after its initiation.
Analysis on Ensemble Methods for the Prediction of Cardiovascular Disease

Coronary Heart disease is one of the dominant sources of death and morbidity for the people worldwide. The identification of cardiac disease in the clinical review is considered one of the main problems. As the amount of data grows increasingly, interpretation and retrieval become even
more complex. In addition, the Ensemble learning prediction model seems to be an important fact in this area of study. The prime aim of this paper is also to forecast CHD accurately. This paper is intended to offer a modern paradigm for prediction of cardiovascular diseases with the use of
such processes such as pre-processing, detection of features, feature selection and classification. The pre-processing will initially be performed using the ordinal encoding technique, and the statistical and the features of higher order are extracted using the Fisher algorithm. Later, the
minimization of record and attribute is performed, in which principle component analysis performs its extensive part in figuring out the “curse of dimensionality.” Lastly, the process of prediction is carried out by the different Ensemble models (SVM, Gaussian Naïve Bayes,
Random forest, K-nearest neighbor, Logistic regression, decision tree and Multilayer perceptron that intake the features with reduced dimensions. Finally, in comparison to such success metrics the reliability of the proposal work is compared and its superiority has been confirmed. From the
analysis, Naïve bayes with regards to accuracy is 98.4% better than other Ensemble algorithms.
