Published: December 2021

A determinação precoce da prenhez em vacas utilizando ultrassonografia pode gerar grande economia e aumento na produção de rebanhos. Observando as evidências de que a perfusão no corpo lúteo fornece um bom parâmetro para determinar à gestação de maneira precoce, este trabalho tem o objetivo de realizar a segmentação de imagens provenientes de doppler aplicados ao aparelho reprodutor de bovinos, de maneira a viabilizar o diagnóstico precoce da prenhez, uma vez que o cálculo da área de perfusão em ultrassom doppler é trivial diante de um corpo lúteo segmentado. Para a realização da tarefa de segmentação foi desenvolvida uma CNN com arquitetura UNet resultando em uma accuracy de 0.8847 no conjunto de imagens teste.

Published: December 2021

Desenvolver novos motores propulsivos, avaliar a queima de combustíveis ou propor novas substâncias de catálise podem ser simulados computacionalmente sem a necessidade de construção de um ambiente real. Para tanto, foi desenvolvido uma aplicação que possibilita representar o funcionamento de uma câmera de combustão. No entanto, a representação discreta de uma simulação possui um expressivo tempo de processamento (horas). Neste artigo são propostas e avaliadas técnicas de paralelização para a aplicação, a fim de executar as simulações em arquitetura multicore. Os resultados obtidos mostram que a aplicação foi mais rápida em uma arquitetura multicore.
A Framework for Executing Protein Sequence Alignment in Cloud Computing Services
Authors: Carvalho Leonardo Reboucas de , Melo Alba Cristina Alves , Araujo Aleteia
Published: December 2021

Protein sequence alignment is a task of great relevance in Bioinformatics and the Hirschberg algorithm is widely used for this task. This work proposes a framework for executing sequence alignment with the Hirschberg algorithm in different cloud computing services. In experiments, our framework was used to align HIV-1 protease sequences using different instances of AWS EC2 and different configurations of AWS Lambda functions.The results show that, for this application, there is a tradeoff between the expected execution time and the cost, e.g., in most cases AWS Lambda provides the best runtime, however at a higher USD cost. In this context, it is important to have a framework that helps in deciding which approach is most appropriate.

Published: December 2021

Neste trabalho é avaliado o uso de placas single-board computers baseadas em ARM para o treinamento de algoritmos de Aprendizado de Máquina (AM). Foi desenvolvido um conjunto experimental treinando o algoritmo XGBoost com 36 configurações de hiperparâmetros em quatro arquiteturas diferentes. Além disso, foi comparado a sua eficiência (consumo energético, custo de aquisição e tempo de execução) com as principais arquiteturas usadas no treinamento de algoritmos de AM (x86 e GPU). Os resultados mostram que este tipo de arquitetura pode se tornar uma alternativa viável e mais verde, não apenas para a inferência, mas também para a fase de treinamento desses algoritmos.

Published: December 2021

Profiling tools are essential to understand the behavior of parallel applications and assist in the optimization process. However, tools such as Perf generate a large amount of data. This way, they require significant storage space, which also complicates reasoning about this large volume of data. Therefore, we propose VisPerf: a tool-chain and an interactive visualization dashboard for Perf data. The VisPerf tool-chain profiles the application and pre-processes the data, reducing the storage space required by about 50 times. Moreover, we used the visualization dashboard to quickly understand the performance of different events and visualize specific threads and functions of a real-world application.

Authors: Ferreira Saulo , Andrade Ermeson , Mendonça Júlio
Published: December 2021

A computação distribuída permite a comunicação entre vários computadores, possibilitando, por exemplo, a distribuição de dados entre eles. No entanto, essa tecnologia traz alguns problemas, como, por exemplo, a consistência dos dados. A consistência dos dados replicados entre os diferentes computadores visa garantir que o mesmo dado seja acessado em todas os computadores em execução. Entretanto, garantir a consistência pode afetar o desempenho, visto que tem suas vantagens e desvantagens. Assim, este trabalho avalia os impactos dos níveis de consistência no desempenho do banco de dados NoSQL (Não Somente SQL) Cassandra, onde diferentes cenários e cargas de trabalho são considerados para analisar os trade-offs que surgem a partir da utilização desses níveis. Nós adotamos uma abordagem experimental para avaliar e analisar o tempo de resposta do sistema quando esses diferentes níveis de consistência e carga de trabalho são utilizados. Os resultados obtidos mostram que a carga de usuários concorrentes acentua a disparidade entre os tempos de resposta que cada um dos níveis apresenta, bem como a quantidade de dados envolvidos nas requisições.

Published: December 2021

Grades computacionais fornecem recursos computacionais sob demanda com alocações definidas por políticas implementadas em algoritmos de escalonamento. O walltime de uma requisição designa o tempo de provisionamento estimado das tarefas, mas este é aproveitado precariamente. Este trabalho propõe o BUCMA, um modelo multialgoritmo de bonificação/punição de fila ao usuário com base em suas estimativas de walltime. Com estimativas mais precisas de walltime, entende-se que essa métrica possa ser incluída a algoritmos de escalonamento, permitindo otimizações no escalonamento dos recursos. Para validação, implementou-se um algoritmo de escalonamento simples aplicado a um cenário fictício de walltime confiável. Os resultados preliminares mostram que o modelo criado apresentou ganhos de fila e de tempo de espera constantes e de até 98%, e o algoritmo de escalonamento, reduções do makespan de até 14,6%, com pior caso em aproximadamente 9%.

Authors: Nunes Alan L. , Melo Alba Cristina Magalhaes Alves de , Boeres Cristina , Oliveira Daniel de , Drummond Lúcia Maria de Assumpção
Published: December 2021

In this paper, we developed a Spark application, named Diff Sequences Spark, which compares 540 SARS-CoV-2 sequences from South America in Amazon EC2 Cloud, generating as output the positions where the differences occur. We analyzed the performance of the proposed application on selected memory and storage optimized virtual machines (VMs) at on-demand and spot markets. The execution times and financial costs of the memory optimized VMs outperformed the storage optimized ones. Regarding the markets, Diff Sequences Spark reduced the average execution times and monetary costs when using spot VMs compared to their respective on-demand VMs, even in scenarios with several spot revocations, benefiting from the low overhead fault tolerance Spark framework.

Medición y evaluación de la comunicación en empresas seleccionadas del gremio de comunicadores de Cancún / Measurement and evaluation of communication in selected companies of the Cancun communicators union
Authors: Rivero-Hernández Magda
Published: December 2021

This paper inquired about how some selected professionals from the guild of communicators in Cancún grouped in the Association of Public Relations of Mexican Caribbean (ARPCM for its initials in Spanish) use measurement and evaluation. The research approach is qualitative, since the interest was to deepen in the phenomenon studied. A bibliographic and documentary review was used to form the theorical basis, as well as a semi-structured interview conducted virtually (which was recorded and subsequently transcribed) to a non-probabilistic purposive sample. Twenty-two subjects belonging to the ARPCM were chosen who met the following conditions: to be an active member of the Association in June 2021, that the terms Public Relations, Communication or Institutional Image appeared in the title of their position, and that they had been in the position for more than three years. Out of a population of 70 active members, 22 were selected: 2 belonging to civil associations, 5 to consulting agencies, 2 to hotels, 2 to restaurants, 3 to recreational parks, 2 to real estate agencies. 2 to travel agencies and 4 representing universities, from which 13 were women and 9 were men. Among the issues on which the interview focused were their conception of measurement and evaluation, whether they were doing it, and their satisfaction with the way in which they were currently carrying out this measurement and evaluation process. Also, there were inquiries about the indicators they used and if they were associated with their communication objectives, the main methods and the use given to the results, as well as the evaluation of the internal communication, indicators employed, among others. The results showed that they give the importance that these issues deserved, but are not completely satisfied with the way they put them into practice. On the other hand, they have evaluation indicators associated with their communication objectives, but the prevalence is on the measurement of products and effects, instead of results and impacts of communication; as well as they focus on reporting activities instead of goals, objectives and results that are correlated with those of the organization. At times of the so-called “new normality”, priority has been given to actions, messages, new media, but there is still something to be done for improvement in their evaluation; which is why, in the future, emphasis will have to be placed on this. Particularly, in improving knowledge about planning, goals, objectives, metrics, indicators, and their scope, as well as the possibilities to determine effects on the organization´s audiences. In view of the above, it is concluded that there is still a long way to go for the guild of communicators in Cancún in this regard.

Psychosocial Features for Hate Speech Detection in Code-switched Texts
Authors:   School of Science and Technology, Africa Nazarene University, Nairobi, Kenya, Ombui Edward , Muchemi Lawrence , Wagacha Peter
Published: December 2021

This study examines the problem of hate speech identification in codeswitched text from social media using a natural language processing approach. It explores different features in training nine models and empirically evaluates their predictiveness in identifying hate speech in a ~50k human-annotated dataset. The study espouses a novel approach to handle this challenge by introducing a hierarchical approach that employs Latent Dirichlet Analysis to generate topic models that help build a high-level Psychosocial feature set that we acronym PDC. PDC groups similar meaning words in word families, which is significant in capturing codeswitching during the preprocessing stage for supervised learning models. The high-level PDC features generated are based on a hate speech annotation framework [1] that is largely informed by the duplex theory of hate [2]. Results obtained from frequency-based models using the PDC feature on the dataset comprising of tweets generated during the 2012 and 2017 presidential elections in Kenya indicate an f-score of 83% (precision: 81%, recall: 85%) in identifying hate speech. The study is significant in that it publicly shares a unique codeswitched dataset for hate speech that is valuable for comparative studies. Secondly, it provides a methodology for building a novel PDC feature set to identify nuanced forms of hate speech, camouflaged in codeswitched data, which conventional methods could not adequately identify.
Drifting and Directed Minds: The Significance of Mind-Wandering for Mental Agency
Authors: Irving Zachary C. ,   Journal of Philosophy Inc.
Published: December 2021

Perhaps the central question in action theory is this: what ingredient of bodily action is missing in mere behavior? But what is an analogous question for mental action? I ask this: what ingredient of active, goal-directed thought is missing in mind-wandering? My answer: attentional guidance. Attention is guided when you would feel pulled back from distractions. In contrast, mind-wandering drifts between topics unchecked. My unique starting point motivates new accounts of four central topics about mental action. First, its causal basis. Mind-wandering is a case study that allows us to tease apart two causes of mental action––guidance and motivation. Second, its experiential character. Goals are rarely the objects of awareness; rather, goals are “phenomenological frames” that carve experience into felt distractions and relevant information. Third, its scope. Intentional mind-wandering is a limit case of action where one actively cultivates passivity. Fourth, my theory offers a novel response to mental action skeptics like Strawson.

Published: December 2021

Background: Literature data indicate the benefit of magnesium (Mg) supplementation. The aim of this study was to examine the effect of short-term Mg supplementation on iron status in healthy female participants. Methods: One hundred healthy female students of the University of Belgrade - Faculty of Pharmacy participated the study during eleven intervention days. Students ingested Mg preparations with the same dose of the active substance. The analysis included the measurement of serum iron, unsaturated iron binding capacity (UIBC), total iron binding capacity (TIBC), total Mg (tMg), ionized Mg (iMg), complete blood count, met-, carboxyand oxy-haemoglobin (metHgb, COHgb, O2Hgb). Transferrin concentrations and percentage of transferrin saturation (SAT) were calculated manually. The association among the analyzed biochemical parameters was examined using polynomial regression. A principal component analysis (PCA) was used for the evaluation of interdependence between the analyzed parameters. Results: A statistically significant trend for change in O2Hgb (%) by tertiles of iMg concentrations was found (P = 0.029). Serum tMg reached significant positive correlation with the SAT at concentration levels greater than 0.9 mmol/L, after 11 days of intervention (R2=0.116). Ionized Mg in a concentration higher than 0.6 mmol/L is positively correlated with SAT and serum Fe (R2=0.214; 0.199, respectively). PCA revealed variability of 64.7% for two axes after 11 days. Conclusions: Mg supplementation leads to an improvement in the certain iron status parameters even in individuals with optimal levels of these indices. However, caution should be exercised when supplementing Mg, and laboratory monitoring of the interaction is required.
A margem da margem: o lugar do feminino na literatura periférica paulista
Authors: Reis Diego dos Santos , Araújo Elisângela
Published: December 2021

O ensaio analisa o protagonismo das escritoras negras de territórios periféricos na literatura marginal, a partir do entrelaçamento entre literatura, política e movimentos insurgentes na cena paulista contemporânea. Para tanto, o texto busca contextualizar a contribuição desse importante acervo poético para os círculos literários femininos, na interlocução entre o biográfico e o político. Trata-se de refletir, ademais, como esses movimentos poéticos-periféricos femininos redefinem identidades e representações, por meio de coletivos de resistência articulados em torno do slam, dos saraus e da poesia ambulante. Para isso, além da revisão bibliográfica, são analisados documentários e videoclipes produzidos por mulheres implicadas com as lutas desses movimentos, considerando o cenário literário dividido em três momentos: a literatura marginal dos anos 2000; a literatura periférica, a partir de 2005; e a literatura periférica feminina, produzida desde 2013, e seus desdobramentos. Por fim, o ensaio tematiza o memoricídio e o apagamento da literatura feminina no Brasil, especialmente da literatura feminina periférica paulista, e as estratégias atuais de denúncia e de resistência que são forjadas por escritoras negras paulistanas, ressignificando não só o espaço público, mas também a potência política de corpos e de territórios marginalizados.

Published: December 2021

A previous report has indicated that in many regions of Indonesia, populations of Musca domestica have shown very high resistance to permethrin and low resistance to imidacloprid. In this study, the resistance status to permethrin and imidacloprid was updated using a topical application and feeding bioassay. Six housefly strains originated from six highly populated cities in Indonesia, namely Serang (SRG), Jakarta (JKT), Bandung (BDG), Semarang (SMG), Yogyakarta (JOG), and Surabaya (SBY). A seventh strain (Danish Pest Infestation Laboratory) served as the control. Each strain was tested for resistance to the two insecticides. The rate of development of resistance to the two insecticides was measured over ten generations. The results indicated that all field strains showed very high resistance to permethrin. The highest resistance level recorded was in the SRG strain (RR50 = 2880), and the lowest was in the JKT strain (RR50 = 520). Repeated application of permethrin over ten generations increased the resistance level by about 2.7–32.73-fold as compared to the level of their respective parental populations. On the other hand, most strains showed low to moderate resistance to imidacloprid, in which the SRG strain had the highest resistance level (RR50 = 15.5) and the SBY strain had the lowest (RR50 = 2.0). Repeated application of imidacloprid over ten generations increased the resistance level by about 3.25–17.41-fold. The findings, which is the second report of housefly resistance in Indonesia since 2016, provide a crucial foundation for developing appropriate housefly integrated pest management strategies in highly populated areas in Indonesia.
Fetus Trafficking in Viet Nam – The New Criminal Method of Human Trafficking
Authors: Thuy Ha Le , Hai Yen Hoang Thi , Quang Bao Nguyen
Published: December 2021

When it comes to basic rights of the fetus, including the right to life, theoretical studies around the world on human rights of the fetus still have not reached an agreement on approaches and explanation. Criminal law at the international and national levels still leaves the possibility of protecting the unborn child. Viet Nam’s criminal law is no exception to this trend. In addition, Viet Nam is currently facing human trafficking with new methods and tricks. Children are bought and paid for while still in the womb, then born abroad and given to traffickers. Children are only protected by criminal law for human trafficking if they are born, alive, and detected by the authorities. While the act of trafficking in fetuses is often easily detected by the authorities right from the stage of purchasing and paying, it is not feasible to prosecute this act for human trafficking under the criminal law of Viet Nam. This reduces the criminal law’s ability to suppress crime, at the same time, leaves many fetuses unprotected. Should criminal law be left outside the legal mechanism to protect children while in the fetal stage? This article suggests considering fetus trafficking as a form of human trafficking and to criminalize fetus trafficking. Criminal law should recognize fetus trafficking as a sign of crime or an early stage in the criminal process of human trafficking, because children need special care and protection, including appropriate legal protection before and after birth, due to their physical and mental immaturity.
“La princesa guerrera enarcó una ceja, mientras el macarra bamboleaba sus atributos bajo el pantalón”. La co-construcción narrativa del homoerotismo en internet
Authors: Garofalo Giovanni
Published: December 2021

Compaginando algunos conceptos medulares de la sociología y del psicoanálisis freudiano con la metodología de la lingüística de corpus, el presente trabajo se inscribe en la senda de los estudios queer de enfoque cuantitativo (Baker, 2004, 2005, 2014, 2018; King, 2015; Milani, 2013) sobre la producción y la regulación social de la sexualidad y del género, para explorar el papel del lenguaje en la construcción del imaginario erótico de una comunidad gay hispanohablante en internet. Con la ayuda de Sketch Engine, se analizan las palabras clave de un corpus de relatos eróticos amateur, gais y lesbianos, para arrojar luz sobre las representaciones simbólicas y los mecanismos discursivos que guían la co-construcción del deseo erótico homosexual, masculino y femenino, en internet. Añadiendo matices significativos para el ámbito cultural hispano, los resultados del análisis confirman la tesis mantenida por Baker (2005), según la cual, al narrar encuentros sexuales fuertemente idealizados, la comunidad homosexual sigue reproduciendo y perpetuando arquetipos ancestrales heteronormativos.

Los resultados señalan que el discurso dominante responde a una lógica defensiva que trata de legitimar un mensaje discriminador.
Studies on water resources salinization along the Italian coast: 30 years of work
Authors: Mastrocicco Micòl
Published: December 2021

The population density on the Italian coasts is twice the national average. Numerous urban, economic, and productive settlements lie along the coast, which in many areas have altered the natural characteristics of the territory. Moreover, recent climate change studies forecast large impacts on the hydrologic cycle in the Mediterranean. Thus, in the next years, coastal water resources will be gradually more stressed. This in turn may result in a progressive salinization, which is a widespread and worrying phenomenon worldwide. In this paper, the historical and geographical distribution of peer-review studies focusing on the salinization of water resources along the Italian coasts will be critically discussed.

Published: December 2021

Gonadotropin-releasing hormone (GnRH) is the primary neuropeptide controlling reproduction in vertebrates. GnRH stimulates follicle-stimulating hormone (FSH) and luteinizing hormone (LH) synthesis via a G-protein-coupled receptor, GnRHR, in the pituitary gland. In mammals, GnRHR lacks a C-terminal cytosolic tail (Ctail) and does not exhibit homologous desensitization. This might be an evolutionary adaptation that enables LH surge generation and ovulation. To test this idea, we fused the chicken GnRHR Ctail to the endogenous murine GnRHR in a transgenic model. The LH surge was blunted, but not blocked in these mice. In contrast, they showed reductions in FSH production, ovarian follicle development, and fertility. Addition of the Ctail altered the nature of agonist-induced calcium signaling required for normal FSH production. The loss of the GnRHR Ctail during mammalian evolution is unlikely to have conferred a selective advantage by enabling the LH surge. The adaptive significance of this specialization remains to be determined.
Stridbara röster i textilslöjdens tjänst
Authors: von Gegerfelt Kronberg Sie
Published: December 2021

Materialet i den här artikeln är främst hämtat ur facktidskriften Svensk Slöjdtidning, organ för Sveriges Slöjdlärarinneförening åren 1960–1969. Ett deskriptivt förhållningssätt samt en kvalitativ textanalys för bearbetning och tolkning av materialet har använts vid granskningen. Avsikten med den valda metodansatsen var att undersöka vilka skribenter som skrev om textilslöjdens innehåll, vad textilslöjd implicerade under 1960-talet och analysera de problem som man brottades med samt hur texterna avspeglar en strävan mot utveckling av slöjdämnet. Textillärare Ingrid Lenberg, då anställd vid Aktiv hushållning är en av de röster som flitigt förekom i tidskriften. Hon var ordförande i Sveriges slöjdlärarinne­förening och en aktiv artikelförfattare med bland annat argument för att konsument­kunskap skulle införas som ett ansvarsområde i slöjdundervisningen. Fil lic. tillika väv- och textillärare Gunhild Engholm skrev också flitigt artiklar rörande textilslöjdens innehåll och tillämpning i grundskolan. Det fria skapandet med kulturarvet som inspiration för elevers egna idéer debatterade hon ofta om. Både Lenberg och Engholm var stridbara förkämpar för hur textilslöjdens innehåll kunde anpassas till samhällsutvecklingen.
Elevers minnen från slöjdundervisning
Authors: Holmberg Annelie
Published: December 2021

Syfte är att i essäform föra ett resonemang om egentillverkade föremåls position i minnen från slöjdundervisning. Varför minns vi föremål och vad kan bidra till minnens tillsynes starka position? Empirin består av skriftliga minnena, i form av ett urval om drygt 200 brev från elever som deltagit i slöjdundervisning. Breven är resultatet av ett publikt upprop inför utställningen Skolslöjd vid Nordiska museet år 2012. Analysen är genomförd genom en kvalitativ textanalys av brevens innehåll. Som stöd i resonemanget kring resultatet av brevens analys används begrepp och tankegångar från litteratur och forskning med fokus på minnen av föremål och ett meningsskapande i samband med tillverkning av föremål. Utöver detta används även forskning om minnen från undervisning.

Background

Corynebacterium pseudotuberculosisis a Gram-positive facultative intracellular pathogen and the etiologic agent of illnesses like caseous lymphadenitis in small ruminants, mastitis in dairy cattle, ulcerative lymphangitis in equines, and oedematous skin disease in buffalos. With the growing advance in high-throughput technologies, genomic studies have been carried out to explore the molecular basis of its virulence and pathogenicity. However, data large-scale functional genomics studies are necessary to complement genomics data and better understating the molecular basis of a given organism. Here we summarize, MS-based proteomics techniques and bioinformatics tools incorporated in genomic functional studies ofC. pseudotuberculosisto discover the different patterns of protein modulation under distinct environmental conditions, and antigenic and drugs targets.

Methodology

In this study we performed an extensive search in Web of Science of original and relevant articles related to methods, strategy, technology, approaches, and bioinformatics tools focused on the functional study of the genome ofC. pseudotuberculosisat the protein level.

Results

Here, we highlight the use of proteomics for understating several aspects of the physiology and pathogenesis ofC. pseudotuberculosisat the protein level. The implementation and use of protocols, strategies, and proteomics approach to characterize the different subcellular fractions of the proteome of this pathogen. In addition, we have discussed the immunoproteomics, immunoinformatics and genetic tools employed to identify targets for immunoassays, drugs, and vaccines againstC. pseudotuberculosisinfection.

Conclusion

In this review, we showed that the combination of proteomics and bioinformatics studies is a suitable strategy to elucidate the functional aspects of theC. pseudotuberculosisgenome. Together, all information generated from these proteomics studies allowed expanding our knowledge about factors related to the pathophysiology of this pathogen.
Violencia económica, física y psicológica en Chile.
Authors: Sanchez Garcia Miguel Rigoberto
Published: December 2021

Este artículo propone que la experiencia de Chile demuestra que los dueños del capital (nacionales o internacionales) no han dudado y no dudarán en utilizar la violencia extrema para imponer un modelo de desarrollo capitalista diseñado para satisfacer las necesidades del capital: las máximas ganancias. Mediante un examen de dos períodos de tiempo, este artículo ofrece ejemplos de los vínculos entre la violencia organizada de la creación y desarrollo de traumas físicos y psicológicos. El análisis establece conexiones entre la violencia de la dictadura de Pinochet y la represión contemporánea utilizada para facilitar la extracción de madera del territorio tradicional mapuche. El artículo muestra cómo la violencia, que fue clave en la imposición del neoliberalismo, después del golpe de Estado de 1973, se mantiene hoy. Las empresas forestales privatizadas y vendidas por Pinochet a la élite, continúan dependiendo del uso de las fuerzas estatales y tácticas represivas de la era de Pinochet para acumular ganancias. Concluye señalando la necesidad de una investigación académica sobre el trauma de las víctimas actuales de la violencia política .
Sobre la onto-fenomenología sartreana. Algunas derivaciones sobre la moral
Authors: De Martino Mónica Solange
Published: December 2021

Esta revisión teórica resume nuestro recorrido por la obra sartreana, colocando énfasis en su onto-fenomenología para posteriormente identificar algunos puntos dilemáticos que derivan de ella. El recorrido bibliográfico básicamente se organiza en torno a dos de sus obras por las que sentimos profundo respeto: El Ser y la Nada (SYN) y Crítica a la Razón dialéctica (CRD). En este texto póstumo pensamos que el autor subsana cierto apego al cogito cartesiano que aún subsiste en SYN y hace presente de manera contundente un orden social injusto y antropofágico. El autor dialoga sobre la vida dilemática, los sentimientos, la experiencia humana, ahogadas por categorías universales y abstractas por parte del idealismo en todas sus vertientes. Tratamos de bosquejar su camino intelectual desde una onto-fenomenología que se apoya en una concepción del ser basada en un solipsismo excesivo a otra claramente vinculada a un ser histórico que es junto a otros. No haremos énfasis en los aspectos metodológicos de la obra del autor. La revisión apunta, en un primer momento, a identificar los mojones de ese recorrido sartreano para, posteriormente, indicar algunos de sus puntos de fuga relacionados con su concepción de la Moral.
Un proyecto de refundación democrática: el alfonsinismo frente al avance del mercado
Authors: Rossi Ignacio Andrés
Published: December 2021

La transición a la democracia en la Argentina formó parte de un proceso político atravesado por amplias transformaciones a nivel macroeconómico nacional, regional y mundial. El gobierno de Raúl Alfonsín (1983-1989) tuvo, luego de una salida democrática sin condicionantes formales, amplios márgenes para comenzar a configurar un régimen político democrático que, con el devenir del triunfo electoral y el apoyo de la ciudadanía, le permitió definir un programa político ambicioso. Este ensayo pretende analizar cómo, desde 1983 el alfonsinismo se propuso construir dicho programa, sus principales dificultades, el espíritu del mismo y algunas reflexiones en torno a los planes económicos y a la reforma del Estado que se sucedieron en aquel entonces. Así, en una primera parte se analiza el contexto macroeconómico mundial y latinoamericano, así como de su impacto nacional en la transición argentina. Luego, se delimitan algunas precisiones sobre el comienzo de la transición a la democracia y el espíritu republicano que el alfonsinismo le imprimió a esta, reflexionando, a su vez, sobre sus propuestas de política económica frente al avance del neoliberalismo internacional.
Léxico y doble discurso del conservadurismo político chileno en la primera mitad del siglo XX
Authors: González de Requena Farré Juan Antonio
Published: December 2021

El artículo propone una reflexión sobre la re-conceptualización de lo local en un contexto de globalización, y analiza en términos teóricos cuáles son las posibilidades efectivas de que se mantengan, refuercen o desencadenan dinámicas de desarrollo local endógeno, entendido como proceso con alto protagonismo de las sociedades locales y, también, como enfoque alternativo. El trabajo se basa en la revisión de la literatura sobre desarrollo local y globalización, y pretende ser un aporte a la discusión sobre estos tópicos. El texto constata la existencia de enfoques que conceptualizan lo local destacando fenómenos como el descentramiento, las redes supralocales, el reforzamiento de las capacidades competitivas de los territorios, el sentido comunitario y las identidades. Planteamos que éste debe entenderse como un “complejo de locales” que pueden tener relaciones entre sí, que el territorio se produce socialmente, y que para adquirir algún carácter de alternatividad en un contexto globalizado, los procesos de desarrollo local endógeno tienen que contar con agentes locales fortalecidos y que actúan desde diversas escalas de la realidad. Destacamos además el rol de los agentes externos: las acciones en y desde escalas mayores pueden ser elementos clave si están en concordancia con orientaciones provenientes de lo local.
Plasma Levels of Fetuin B and Fibrinogen in Chronic Obstructive Pulmonary Disease: A Preliminary Cross-sectional Study
Authors: Swathini CV Shri , Chowdary MVP
Published: December 2021

Introduction: Recent exploratory proteomics study reported increased blood levels of Fetuin B (FETUB) in Chronic Obstructive Pulmonary Disease (COPD). Growing body of evidence demonstrates fibrinogen not only as acute phase reactant but also possesses features advocating as biomarker of COPD. Aim: To determine the blood levels of FETUB and fibrinogen independently as well as in combination COPD and among severity of COPD. Materials and Methods: A single-centred cross-sectional study of eight months duration was conducted during May to December 2017. A total of 76 blood samples (38 COPD patients and 38 controls) were recruited. Based on distribution, parametric and non parametric statistical tools were used. Analysis of co-variance and multiple multivariate linear regression models were utilised to assess the influence of clinical data on FETUB. Steel-Dwass-Critchlow- Fligner method was employed for multiple pairwise comparisons. Receiver Operating Characteristic (ROC) curve were generated to compute cut-off of FETUB, fibrinogen and their combination. Results: The median age of subjects were 57 years with an IQR of 50-66 years for controls whereas 58 years (IQR 50-65 years) for COPD subjects. In comparison to controls, a significant increase in blood levels of both FETUB and fibrinogen in COPD and Global Initiative for Chronic Obstructive Lung Disease (GOLD) stages of COPD was prominent. Among COPD grades, differences of FETUB levels were significant in GOLD I vs II and GOLD IV vs I, II and III whereas fibrinogen levels in GOLD III from GOLD IV. FETUB showed independent correlation with Forced Expiratory Volume (FEV) 1% pred and severity of COPD. A moderate improvement in combined (FETUB+fibrinogen) analysis of control vs COPD was noticed. Conclusion: The present study demonstrates significant increase in blood levels of FETUB in COPD and among the severity of COPD in comparison to fibrinogen. Hence, FETUB can be a more promising probable inflammatory biomarker in COPD.

Published: December 2021

Introduction: Acute Exacerbation of Chronic Obstructive Pulmonary Disease (AECOPD) is a common health problem coupled with huge mortality and morbidity across the world. Acute exacerbation in COPD patients leads to electrolyte disturbances. Routinely, electrolytes are measured from venous blood. Electrolytes can also be measured from whole blood by blood gas analyser along with blood gases measurement. Aim: To study the correlation between venous and arterial blood electrolytes in AECOPD patients. Materials and Methods: The cross-sectional study was conducted at Clinical Biochemistry Laboratory, Government Medical College and Sir Takhtsinhji General Hospital, Bhavnagar, Gujarat, India, from December 2013 to May 2014. Arterial and venous blood were taken at same time from 150 patients of AECOPD and analysed for electrolytes (sodium, potassium and ionised calcium) in arterial blood gas analyser. Correlation of arterial and venous blood electrolyte levels was done by Pearson’s correlation. Results: This study comprised 109 (72.67%) male and 41 (27.33%) female AECOPD patients. Mean age of subjects was 59.01±11.42 years. Mean level of arterial sodium was 143.1±8.81 mmol/L and venous sodium was 144.8±8.47 mmol/L (p-value=0.0973). Mean level of arterial potassium was 3.53±0.73 mmol/L and venous potassium was 3.19±0.56 mmol/L (p-value <0.0001). Mean level of arterial ionised calcium was 0.83±0.13 mmol/L and venous ionised calcium was 0.76±0.17 mmol/L (p-value <0.0001). Correlation coefficient values for sodium, potassium and ionised calcium were 0.878, 0.762 and 0.537, respectively. Conclusion: Arterial sodium and potassium can be used as a substitute of venous sodium and potassium in management of AECOPD patients, while arterial ionised calcium should not be used in place of venous ionised calcium in management of such patients.
