ADAM AND EVE ACCORDING TO EÇA AND MACHADO
Authors: Dixon Paul
Published: May 2020

Both Eça de Queirós and Machado de Assis wrote stories about Adam and Eve, defamiliarizing in different ways the original Biblical narrative. Their deviations from the source are consistent with the general esthetic programs they established in their overall production. Through masterful detail, Eça creates a kind of Darwinian Garden of Eden, which continually tests the original parents, threatening their survival, and in the process facilitates their slow development into the capable human beings we recognize. Machado’s story is neither romantic nor naturalistic, but rather a quirky philosophical and metaliterary entertainment that plays with narrative devices. A frame story, in which the narrator of the interior story ends up denying the validity of tale he has offered, creates an ungrounded narrator. The sense of confused giddiness produced in the narrator’s audience suggests by implication an expected reader’s reaction to the short story itself. In different ways, the Edenic narratives of the Portuguese and Brazilian masters disturb readers’ comfortable assumptions regarding Adam and Eve, and encourage them to question this received wisdom.
“NECKTIES OF A CERTAIN COLOR” – POLITICAL ENGAGEMENT IN MACHADO DE ASSIS’S ESAÚ E JACÓ
Authors: Namorato Luciana
Published: May 2020

Machado de Assis’s view of politics is a controversial topic. Since the late nineteenth century, critics have diverged on the degree and nature of the Brazilian writer’s political engagement, as registered in his crônicas, short stories, and novels. I begin my essay with a review of the most important critical works that touch upon this theme, and propose that Machado often comments on politics in his fiction, but that he does so in a subtle, indirect manner. In this essay, I focus on Machado’s novel Esaú e Jacó, and argue that the metafictional observations that abound in this novel can be applied not only to fictional narratives, but also to political discourse. I interpret these metafictional comments as Machado’s strategy to highlight the partial and subjective quality of political discourse. Finally, I analyze the protagonists of the novel, the twins Pedro and Paulo, as symbols of the paradoxical nature of human beings and, by extension, the instability of individual political opinions.

Entrevista a Mário de Carvalho
INTRODUCCIÓN A LA SÁTIRA COMO PROBLEMA ESTÉTICO GENERAL
Authors: Haro Pedro Aullón de
Published: May 2020

El presente artículo aborda el problema de la sátira-lo satírico en su posibilidad más amplia, considerando que se trata en conclusión de una entidad sujeta a intencionalidad crítica y por tanto nunca plenamente asignable a valor categorial estético, al modo bello, sublime o humorístico, valores sostenibles en su autonomía. Este argumento se funda en el examen de la sátira desde criterio tanto constitutivo (vida y arte) como teorético (géneros, realizaciones universales dadas, poetología y valores estéticos categoriales). Tanto el examen de los constituyentes como de los momentos universales e históricos ofrecen el tránsito de un rico horizonte artístico y ético, de la continuidad y la discontinuidad, pero convergen en último término en la permanencia de la intencionalidad crítica y la consiguiente indeterminabilidad estética categorial.

A INCÓMODA SÁTIRA: MATIZES SATÍRICOS EM MÁRIO DE CARVALHO
Authors: Simões Maria João
Published: May 2020

A sátira tem sido objeto de estudo ao longo dos tempos, sendo notório, nos nossos dias, um recrudescimento da atenção por parte da crítica relativamente ao seu funcionamento, sobretudo porque se reconhece a sua capacidade de adaptação e de mutação. Com base na investigação de teóricos reconhecidos como Sophie Duval e Fredric V. Bogel, entre outros, procurar- se-á mostrar, neste estudo, a labilidade da sátira que, extravasando os limites genológicos, se difunde por diferentes formas discursivas e literárias e alcança um potencial de modernidade que anteriormente lhe era negado. Apontar-se-ão diferentes abordagens teóricas e investigar-se-á diversidade de elementos que a sátira congrega. Sustentado por essa pesquisa teórica, realizar-se-á uma análise de obras Mário de Carvalho com marcada feição satírica, nomeadamente a obra Quando o diabo reza, tendo como objetivo identificar as principais estratégias e alguns procedimentos utilizados pelo autor para atingir os seus intentos satíricos; observar-se-á ainda a permeabilidade das fronteiras da sátira relativamente a procedimentos estético-estilísticos que lhe são próximos, como a paródia e o humor.
METAMORFOSES DO RISÍVEL NA SÁTIRA CONTEMPORÂNEA. REGISTOS SATÍRICOS E IMPLÍCITOS AXIOLÓGICOS EM TEXTOS FICCIONAIS DE GONÇALO M. TAVARES
Authors: Mariano Maria do Rosário Neto
Published: May 2020

O trabalho que me propus desenvolver, no âmbito da Sátira literária e Reflexão política/social, partirá de pressupostos ideológicos e contextos civilizacionais pós-modernos, que valorizam o humor nivelador e eticamente neutro ou cético, associado a práticas de socialização já, em grande medida, “pós-humanistas”. Contudo, é no âmbito destes pressupostos e contextos que emerge, contrastivamente, parte da ficção narrativa de Gonçalo M. Tavares em registo satírico, quer seja de dominante paródica e burlesca mas próxima do humor, logo, complacente e inclusiva, quer evidencie maior predominância dos modos irónico, sarcástico ou grotesco, na complexa polifonia desconstrutiva ou demolidoramente crítica assumida pelo autor- -narrador face às patologias das personagens, nas suas práticas sociais, cívicas e/ou políticas. Será concretamente visado o corpus constituído pelas obras O Senhor Valéry e O Senhor Juarroz, do políptico O Bairro, a coletânea de contos Água, cão, cavalo, cabeça e o romance Aprender a rezar na Era da Técnica.
ALGUM LUGAR, DE PALOMA VIDAL: DESLOCAMENTO, ESTRANHAMENTO E MELANCOLIA
Authors: Mello Ana Maria Lisboa de
Published: May 2020

São recorrentes, no romance brasileiro contemporâneo, sobretudo a partir da década de 1990, deslocamentos e mudanças espaciais de personagens que, situados temporariamente em outros países e culturas, enfrentam a solidão, o estranhamento e empreendem a busca de si mesmos. Nessa perspectiva, analisamos o romance Algum lugar (2009), de Paloma Vidal. A protagonista e seu companheiro deslocam-se do Rio de Janeiro para cumprir estágio de pesquisa em Los Angeles. A cidade norte-americana, com grandes avenidas, vazias de pessoas, e supremacia do automóvel, mostra-se hostil, semelhante ao “não-lugar”, caracterizado por Marc Augé. A cidade é o retrato de um mundo que se tornou hostil ao convívio humano; a configuração da cidade suprime a possibilidade do encontro, fato que dilacera o indivíduo, cada vez mais só, exilado de si mesmo, dividido entre o sonho e a realidade devoradora e habitado por uma falta indefinida, um vazio existencial.
DILATAÇÃO DO REAL E LIGAÇÕES INFINDAS: A BONECA DE KOKOSCHKA, O LIVRO MATRIOSCA DE AFONSO CRUZ
Authors: Amorim Sílvia
Published: May 2020

O romance de Afonso Cruz A Boneca de Kokoschka (2010) inscreve-se numa rede de obras oriundas de áreas e campos variados que retomam a figura da boneca do pintor Kokoschka. Essas obras pululam, tecendo entre elas relações de inclusão e contiguidade, levando-nos a perder de vista a matriz orginal e favorecendo o diálogo interartístico. No romance, a boneca põe em destaque a tendência da ficção para se expandir, especialmente graças à “transficcionalidade”, e a transgressão repetida da fronteira entre o real e a ficção, nomeadamente através de metalepses. Dessarte, A Boneca de Kokoschka personifica algumas tendências do romance contemporâneo, delineando os contronos de um novo paradigma literário ainda por definir.
Refigurações garrettianas de “romances” e outros textos tradicionais
Authors: Monteiro Ofélia Paiva
Published: May 2020

Muito interessado pelo Romanceiro desde o contacto, no exílio, com a cultura romântica, Garrett dedicou-se (pioneiramente, no espaço peninsular) não só à recolha de versões romancísticas, mas também à criação de poemas, inspirados em romances, onde procura aproximar-se formal e tematicamente da poesia tradicional, impregnando todavia as composições da sua marca, ao “reconstruir” o fundo antigo com “cimento” e “enchume” seus (cf. “Introdução” de Garrett a O Chapim d’El-Rei ou Parras Verdes). O vasto espólio manuscrito, deixado por Garrett, de materiais destinados ao Romanceiro documenta que estas atividades – a compiladora e a criativa – permaneceram durante toda a sua vida. A análise de Adozinda, Bernal Francês, O Chapim d’El-Rei e Miragaia exemplificará a refiguração praticada nos romances “reconstruídos”: o “cimento” garrettiano emacia e espiritualiza a crueza primitiva, recompondo situações e complexificando a psicologia das personagens.

Spoliarium (1888), de Joaquín Dicenta: germen literario de su obra posterior
Authors: Jiménez María Isabel
Published: May 2020

Este artículo analiza el primer volumen de cuentos y crónicas de Joaquín Dicenta: Spoliarium. Cuadros sociales (1888), publicado el mismo año en que inicia su trayectoria teatral. Es un libro completamente olvidado, pero de sumo interés por el fuerte compromiso que muestra con su realidad social y por la época bohemia en que lo redacta. Estudio, entre otros aspectos, su transmisión literaria, el significado del título, la interesante huella autobiográfica, su vinculación con el Naturalismo, los temas y personajes. Lo más importante de todo ello es que, en germen, aparecen en Spoliarium muchas características que desarrollará Dicenta en su obra posterior.
Coordinación Intergubernamental en Políticas Ambientales. La Ley de Bosques Nativos en las Regiones Forestales: Parque Chaqueño y Bosque Andino-Patagónico (2008-2012)
Authors: Figueroa Lucas M.
Published: May 2020

La coordinación intergubernamental constituye un factor central para que las políticas nacionales alcancen una implementación homogénea. No obstante, dentro de los estudios sobre la coordinación se sostiene que, entre sus tipos, la coordinación horizontal (entre jurisdicciones de un mismo nivel de gobierno) tiende a no ocurrir. Poniendo en discusión este postulado, este trabajo se pregunta ¿Cuáles son los factores que producen que las jurisdicciones subnacionales decidan actuar de manera conjunta para implementar una política ambiental nacional? Partiendo del análisis comparativo del proceso de formulación de las leyes de adecuación normativa a la Ley Nacional de Bosques Nativos en Argentina, se argumenta que las provincias actúan conjuntamente cuando hay un marco institucional formalizado y legítimo disponible para ser utilizado en los momentos en que una estructura de incentivos produce que los políticos locales decidan formular e implementar una política ambiental homogénea en sus jurisdicciones.

Partai Politik, Rekrutmen Politik dan Pembentukan Dinasti Politik pada Pemilihan Kepala Daerah (Pilkada)
Authors: Fitriyah Fitriyah
Published: May 2020

Pasca terbit Putusan Mahkamah Konstitusi No.33/PUU-Xlll/2015 sebagai pem-batalan larangan politik dinasti, sejumlah calon  dari kerabat petahana maju dalam Pilkada 2015 dan terus berlanjut di pilkada setelahnya. Selain karena hambatan regulasi yang telah dianulir oleh Mahkamah Konstitusi, maraknya calon yang berlatar belakang dinasti terindikasi adanya masalah di partai politik dalam melaksanakan fungsi rekrutmen politik. Artikel ini berusaha menjelaskan bagaimana partai-partai politik melaksanakan proses rekrutmen politik untuk pencalonan pilkada yang ikut menyuburkan politik dinasti. Artikel ini menggunakan data dari studi literatur, hasilnya menunjukkan bahwa rekrutmen politik untuk pencalonan pilkada oleh partai politik  bersifat sentralistis dan informal, serta menggunakan pertimbangan pragmatis dengan menambahkan syarat  kemampuan finansial dan tingkat elektabilitas calon, sehingga lebih memberi jalan bagi calon yang berlatar belakang dinasti.

Published: May 2020

Penelitian ini mendiskusikan faktor-faktor yang menghambat keterwakilan caleg perempuan di ranah lokal dalam konteks Pemilu Legislatif 2014 di Kabupaten Nagekeo, Nusa Tenggara Timur. Penelitian ini menggunakan metode deskriptif kualitatif dengan mewawancarai informan yang merupakan kandidat pemilu legislative tahun 2014. Temuan penelitian menunjukkan kendala utama keterwakilan perempuan terletak di politik partai yang lebih memprioritaskan calon legislatif (caleg) laki-laki dibandingkan caleg perempuan. Penentuan nomor urut juga berat sebelah. Caleg perempuan ditempatkan pada nomor “urut sepatu”. Hambatan kedua pada faktor sosial ekonomi. Dukungan sumber-sumber keuangan bagi caleg perempuan sangat minim. Ketiga adalah hendala kultural budaya terkait dengan kuatnya budaya patriarki di daerah. Perempuan terikat dengan tradisi belis yang dianggap sebagai warge kelas dua. Keempat terkait hambatan dalam diri perempuan sendiri. Calon anggota legislatif perempuan tidak memanfaatkan kelompok-kelompok organisasi kemasyarakatan untuk mendukung mereka dalam berkompetisi dengan caleg laki-laki.

Published: May 2020

The relatively high silica content in bagasse ash can be used as raw material for making zeolite. Zeolite can be used as a heavy metal adsorbent in industrial wastewater treatment. This study aims to synthesize zeolite from bagasse ash and to apply zeolite as an adsorbent of Cu(II) in a continuous system reactor. The effects of contact time, zeolite size, and concentration of Cu(II) solution on the removal efficiency of metals have been studied in this research. The synthesis of zeolite was carried out using the hydrothermal method at 100°C for 7 hours. The synthesized zeolite was characterized using SEM-EDX, XRD, FTIR, and BET The adsorption process was carried out using a continuous reactor with a flow rate of 0.4 L/min and flowed for 60 minutes with sampling at 15-minute intervals. The zeolite size used was 100 and 200 mesh. The results of SEM-EDX analysis showed that Zeolite has an irregular morphology and contains Si at 35.15%. The XRD results show that the zeolite crystallinity is relatively low. The specific surface area of zeolite at size 100 mesh and 200 mesh were 439.48 m2 /g and 697.76 m2/g respectively. The best Cu(II) waste adsorption test results were obtained under zeolite conditions with a particle size of 200 mesh, the concentration of Cu(II) wastewater of 25 mg/L, and an operational time of 60 minutes with a removal efficiency of Cu(II) of 41.57%

Phytochemical analysis and antioxidant activity of leaf extracts of some selected plants of the family Acanthaceae
Authors: Kripasana Kshetrimayum , Xavier Jobi
Published: May 2020

The present era of scientific research has witnessed an enumerable amount of evidences to showcase the immense potential of medicinal plants. In the present investigation, the phytochemical analysis of Phlogacanthus pubinervius T. Anderson., Adhatoda vasica (L.) Nees,Phlogacanthus thyrsiflorus Nees, Phlogacanthus curviflorus (Wall.) Nees, and Ruellia tuberosa L. was carried out for the different plants extracted with methanol. Analysis was carried out to estimate the quantity of phenols, carbohydrates, tannins, flavonoids and proteins. The antioxidant property of these plants were analysed using DPPH method. The concentration of the plant samples required to decrease the DPPH concentration by 50% was calculated by interpolation from linear regression analysis and denoted IC50 value (µg/ml). The qualitative analysis showed the presence of alkaloids, tannins, saponins, proteins, carbohydrate and phenols in all the sample extracts. The highest amount of tannins and phenols was observed in P. thyrsiflorus. P. pubinervius (77.83%), A. vasica (74.81%), P. curviflorus (94.20%), and R. tuberosa (70.78%) which showed highest antioxidant activity of DPPH-scavenging at 150 µg/ml of methanol extract. The high percent of scavenging activities of those plants add value to their medicinal properties. The presence of the high amount of phytochemical compounds suggests that the plants have high amount of medicinal compounds and can be extensively used to extract the natural compounds.
Dash

Published: May 2020

Byte-addressable persistent memory (PM) brings hash tables the potential of low latency, cheap persistence and instant recovery. The recent advent of Intel Optane DC Persistent Memory Modules (DCPMM) further accelerates this trend. Many new hash table designs have been proposed, but most of them were based on emulation and perform sub-optimally on real PM. They were also piece-wise and partial solutions that side-step many important properties, in particular good scalability, high load factor and instant recovery.

We present Dash, a holistic approach to building dynamic and scalable hash tables on real PM hardware with all the aforementioned properties. Based on Dash, we adapted two popular dynamic hashing schemes (extendible hashing and linear hashing). On a 24-core machine with Intel Optane DCPMM, we show that compared to state-of-the-art, Dash-enabled hash tables can achieve up to ∼3.9× higher performance with up to over 90% load factor and an instant recovery time of 57ms regardless of data size.
The PGM-index
Authors: Ferragina Paolo , Vinciguerra Giorgio
Published: May 2020

We present the first learned index that supports predecessor, range queries and updates within provably efficient time and space bounds in the worst case. In the (static) context of just predecessor and range queries these bounds turn out to be optimal. We call this learned index the Piecewise Geometric Model index (PGM-index). Its flexible design allows us to introduce three variants which are novel in the context of learned data structures. The first variant of the PGM-index is able to adapt itself to the distribution of the query operations, thus resulting in the first known distribution-aware learned index to date. The second variant exploits the repetitiveness possibly present at the level of the learned models that compose the PGM-index to further compress its succinct space footprint. The third one is a multicriteria variant of the PGM-index that efficiently auto-tunes itself in a few seconds over hundreds of millions of keys to satisfy space-time constraints which evolve over time across users, devices and applications.

These theoretical achievements are supported by a large set of experimental results on known datasets which show that the fully-dynamic PGM-index improves the space occupancy of existing traditional and learned indexes by up to three orders of magnitude, while still achieving their same or even better query and update time efficiency. As an example, in the static setting of predecessor and range queries, the PGM-index matches the query performance of a cache-optimised static B+-tree within two orders of magnitude (83×) less space; whereas in the fully-dynamic setting, where insertions and deletions are allowed, the PGM-index improves the query and update time performance of a B
+
-tree by up to 71% within three orders of magnitude (1140×) less space.

With the growing market of cloud databases, careful detection and elimination of slow queries are of great importance to service stability. Previous studies focus on optimizing the slow queries that result from internal reasons (e.g., poorly-written SQLs). In this work, we discover a different set of slow queries which might be more hazardous to database users than other slow queries. We name such queries Intermittent Slow Queries (iSQs), because they usually result from intermittent performance issues that are external (e.g., at database or machine levels). Diagnosing root causes of iSQs is a tough but very valuable task.

This paper presents iSQUAD, Intermittent Slow QUery Anomaly Diagnoser, a framework that can diagnose the root causes of iSQs with a loose requirement for human intervention. Due to the complexity of this issue, a machine learning approach comes to light naturally to draw the interconnection between iSQs and root causes, but it faces challenges in terms of versatility, labeling overhead and interpretability. To tackle these challenges, we design four components, i.e., Anomaly Extraction, Dependency Cleansing, Type-Oriented Pattern Integration Clustering (TOPIC) and Bayesian Case Model. iSQUAD consists of an offline clustering & explanation stage and an online root cause diagnosis & update stage. DBAs need to label each iSQ cluster only once at the offline stage unless a new type of iSQs emerges at the online stage. Our evaluations on real-world datasets from Alibaba OLTP Database show that iSQUAD achieves an iSQ root cause diagnosis average F1-score of 80.4%, and outperforms existing diagnostic tools in terms of accuracy and efficiency.

There is growing interest in graph pattern mining (GPM) problems such as motif counting. GPM systems have been developed to provide unified interfaces for programming algorithms for these problems and for running them on parallel systems. However, existing systems may take hours to mine even simple patterns in moderate-sized graphs, which significantly limits their real-world usability.

We present
Pangolin
, an efficient and flexible in-memory GPM framework targeting shared-memory CPUs and GPUs. Pangolin is the first GPM system that provides high-level abstractions for GPU processing. It provides a simple programming interface based on the extend-reduce-filter model, which allows users to specify application specific knowledge for search space pruning and isomorphism test elimination. We describe novel optimizations that exploit locality, reduce memory consumption, and mitigate the overheads of dynamic memory allocation and synchronization.

Evaluation on a 28-core CPU demonstrates that Pangolin outperforms existing GPM frameworks Arabesque, RStream, and Fractal by 49×, 88×, and 80× on average, respectively. Acceleration on a V100 GPU further improves performance of Pangolin by 15× on average. Compared to state-of-the-art hand-optimized GPM applications, Pangolin provides competitive performance with less programming effort.

Into the Wilderness: Rediscovering Titus Smith Jr’s philosophy of nature
Authors: Field Richarld H.
Published: May 2020

Except in some academic circles, Titus Smith Jr. is mostly a forgotten man. The year 2018 marked the 250th anniversary of Titus Smith Jr’s. birth in Granby, Massachusetts (1768-1850). While general articles about Smith’s life exist (Punch 1978), surprisingly there have only been three serious studies celebrating his knowledge and scientific thinking (Piers 1938, Clark 1954, Gorham 1955). Smith lived prior to the era when science hardened into specialized fields and when a single mind could move between disciplines allowing each to inform the other. Smith’s interdisciplinary methods and his belief that nature is a global force are once again coming to the forefront as climate change emerges as the single most important threat to the survival of the planet. This essay attempts to bring this 19th century philosopher of nature into a modern environmental context.

Authors: Farahmand Mahnaz , Khooshab Elham , Hasanzadeh Fahimeh , Amooee Sedigheh , Akbarzadeh Marzieh
Published: May 2020

Objectives: Perineal warm packs with an increase in subcutaneous temperature and the stimulation of cutaneous receptors are advocated in the belief of pain and probably increase comfort during labor and delivery. This study aimed to investigate the effectiveness of warm compress bi-stage on pain strength in the first two stages of labor and after delivery in primiparous women. Materials and Methods: This study was a randomized clinical trial that was conducted in Shiraz hospitals from July 2012 to March 2013, in which 150 women participated and were separated into intervention (15-20-minute warm compress bi-stage in the first two stages of normal delivery at 7 and 10 cm dilations and zero position) and control (just usual hospital cares) groups. Then, pain strength was evaluated in both groups in the first two stages of normal delivery and after delivery similar to the frequency of episiotomy. The chi-square, t test, and odds ratio analysis were used for data analysis Results: The results of the t test showed that the mean intensity of pain reduced significantly in intervention group in both first (P<0.002) and second stages (P<0.001) and on the day after delivery (P<0.001). Besides, the frequency of episiotomy meaningfully decreased in the intervention group in comparison with the control group (P<0.001). Conclusions: The research participants experienced less pain through the labor and after delivery by using warm compress bi-stage at 7 and 10 cm dilatations. Thus, this method might be suitable for reducing perineal pain resulting from episiotomy
Questionnaire on Mothers’ Cultural Beliefs About Weaning: Development and Psychometric Evaluation
Authors: Jannat-Alipoor Zahra , Navabi Nasrin , Ebadi Abbas , Ghaffari Fatemeh
Published: May 2020

Objectives: This study was designed to investigate the role of cultural beliefs on weaning. Therefore, the obtained results can be used for health policymakers who design strategies to prevent physical and mental damage to mothers and their children. The main objective of this study was to design a questionnaire probing the role of cultural beliefs on weaning. Materials and Methods: The sequential combination exploratory mixed methods design was used to develop the questionnaire format in two sections. The qualitative section was designed to probe the role of cultural beliefs on weaning, which included a literature and related tools review and fieldwork (semi-structured interviews with mothers). Twenty-two studies were examined in the literature review and 14 mothers were selected and interviewed by a purposive sampling technique. The interviews continued up to data saturation as well. In addition, data analyses for both steps were conducted using conventional and textual content analyses. The quantitative section was a methodology study that was accomplished in two parts. Questionnaire items were formed using the data and item pool obtained from the first part. Finally, the psychometric properties of the questionnaire were checked using face, content, and construct validity, followed by probing reliability using Cronbach’s alpha reliability in the second part. Results: Qualitative data analysis results were organized according to the foundational issues regarding the need for weaning, attitude toward weaning, awareness about weaning, society’s culture, health literacy, self-action, others’ experiences, professional help, family members’ support, and the outcomes. The item pool was formed using literature reviews and interviews. A 49-item questionnaire was developed after the completion of the psychometric process. The Kaiser-Meyer-Olkin Index of Sampling Adequacy and Bartlett’s test of sphericity showed good results in this regard. Five components from the exploratory content analysis encompassing contexts, solutions, searching for help, maternal outcomes, and child-related outcomes demonstrated a 62.112% variance. Further, the Cronbach’s alpha was 0.88 and the interclass correlation coefficient was 0.89 based on responses to the items over two administrations of the questionnaire (P < 0.001). Thus, these results showed a high level of tool stability. Conclusions: For this study, a questionnaire was developed for understanding the role of cultural beliefs on weaning. It can be used for educational, research, and treatment purposes as a tool with appropriate validity and reliability, as well as short, easy, and grammatically simple items. Eventually, the questionnaire is useful for examining mothers’ false beliefs about weaning and their educational needs since false beliefs could cause destructive and health-threatening behaviors.
Doppler Ultrasound Screening of the Uterine Arteries as a Predictor for Early Miscarriage
Authors: Ghazi Rifat Aseel
Published: May 2020

Objectives: So far, there is no concrete consensus on using uterine Doppler measurements for predicting the adverse outcomes in the early stages of pregnancy between 6-14 weeks. Hence, the current study was planned to investigate the role of uterine artery Doppler in predicting the miscarriage in early pregnancy and to evaluate whether uterine artery Doppler indices abnormality is associated with a complicated pregnancy and adverse outcomes. Materials and Methods: The present cross-sectional prospective study estimated the uterine artery Doppler of right and left uterine arteries and the mean of pulsatility index (PI), resistance index (RI), and systolic/diastolic (SD) ratio was obtained for each patient. The gestational age, at which the Doppler study was performed, was 6-14 weeks for all groups. Finally, the groups of normal and threatened miscarriage were followed up for the outcome up to 20 weeks of gestation. Results: There was a significant difference in the means of PI, RI, and S/D ratio among the three groups. However, PI was the only parameter which was significantly associated with the outcome of pregnancy. In addition, the cut-off value for PI was 2.64 at 91% sensitivity and 81% specificity for predicting miscarriage. Conclusions: In general, uterine artery Doppler should be introduced as the routine screening test for identifying the women who could have an adverse pregnancy outcome for its effective management.

Objectives: Prediction of nausea and vomiting can positively contribute to the management of this post-anesthesia adverse effect. Therefore, the present study aimed to design and implement a checklist for predicting anesthesia-induced nausea and vomiting in candidate patients for mastectomy. Materials and Methods: This methodological study was conducted on 300 candidate patients for mastectomy during 2018-2019 at Imam Reza hospital, Tabriz, Iran. The checklist items were designed and developed based on scientific articles, expert opinions, and patient interviews. The Pearson correlation coefficient, Cronbach’s alpha, Spearman-Brown coefficient, factor analysis, the KaiserMeyer-Olsen measure of sampling adequacy, and VARIMAX rotation were used to analyze the data. Eventually, the distribution of data with a normal distribution was compared through the Kolmogorov-Smirnov test. Results: In the first stage, 100 items were collected, which were reduced to 35 cases after modification by a team of experts. Twenty items were ultimately selected after observing the 80/20 response rate. The overall scale reliability was calculated as 0.953 based on Cronbach’s alpha. The correlation coefficient of the first and second implementations was 0.853. Finally, the four extracted factors accounted for 69.51 of the variance of the checklist based on factor analysis. Conclusions: The prediction checklist for post-anesthesia nausea and vomiting in candidate patients for mastectomy comprised adequate psychometric indicators that could be used with high reliability according to the extracted indices.

The novel severe acute respiratory syndrome coronavirus 2 is a worldwide pandemic. The severe morbidity and mortality associated with coronavirus disease 2019 has mostly affected the elderly or those with underlying medical conditions. We present a case of a 12-year-old girl with no past medical history who presented with fever, cough, and vomiting. Laboratory evaluation revealed severe thrombocytopenia and elevated markers of inflammation. The patient progressed to respiratory failure, and testing results for the severe acute respiratory syndrome coronavirus 2 returned positive. Because of the severity of her thrombocytopenia, she was treated with intravenous immunoglobulin and steroids with prompt improvement in platelets. The patient’s severe acute respiratory distress syndrome was managed with mechanical ventilation, inhaled nitric oxide, and then airway pressure release ventilation. After azithromycin and hydroxychloroquine were given without improvement, our patient received tocilizumab, an anti–interleukin-6 receptor antibody, and remdesivir, a broad antiviral agent, with significant clinical benefit soon afterward. Given that severe pediatric coronavirus disease 2019 is rare, we hope to inform pediatric providers on the clinical course and management considerations as this pandemic continues to spread.

Authors: Martynova K.V. , Martynov A.V.
Published: May 2020

Embolemidae is a small family of chrysidoid wasps (Hymenoptera: Chrysidoidea) understudied in Ukraine. The cosmopolitan genus Embolemus is shown comprising only 32 extant and 2 fossil species in the world fauna: the actual check-list for the genus is given. Only two species had been previously registered in Ukraine. Embolemus ruddii was recorded at Western Ukraine and Crimea, and E. tauricus was described from Crimea based on a single specimen collected at 1910. In present contribution E. tauricus is recorded for continental Ukraine for the first time from the Zaporizhia Region. The specimen collected almost fully correspond to the original description of the species, differing only in the small features of coloration. The habitat of E. tauricus is briefly described.
Redes comerciales en la segunda mitad del siglo XIX: comerciantes antioqueños y firmas extranjeras
Authors: Mesa-Bedoya Ana María
Published: May 2020

Colombia se vinculó al comercio internacional a través de la importación de mercancías y la exportación de productos en la segunda mitad del siglo XIX. Las comunicaciones regulares entre importadores mayoristas y firmas extranjeras muestran que aquellos estaban bien conectados y que estas ofrecían diferentes ventajas a clientes de lugares distantes. El propósito de este artículo es analizar cómo las redes de contactos de los comerciantes locales Uribe Ruiz, de Rionegro (Antioquia, Colombia), facilitaron la conexión del país con la economía internacional. Este análisis responde a través de un estudio de caso a las siguientes preguntas: ¿cómo se establecían las relaciones comerciales con firmas extranjeras?, ¿quiénes conformaban una red comercial internacional y qué productos negociaban? y ¿cómo fortalecían dichas relaciones? La metodología, de tipo cualitativo, se basa en el análisis de una base empírica amplia compuesta principalmente por la correspondencia epistolar de la familia Uribe Ruiz. La reconstrucción de la red permitió identificar firmas extranjeras, el tipo de productos que ofrecían y cómo se establecieron relaciones comerciales en mercados distantes. A diferencia de la mayoría de los estudios sobre redes comerciales en Colombia, que exploran las relaciones internas, aquí el uso de la correspondencia sirvió para determinar el tamaño de la red internacional y sus agentes.
“Paliar el atraso”. Tuluá, una ciudad progresista: 1910-1948
Authors: Arias-Solarte Juan Pablo
Published: May 2020

El presente artículo ofrece una interpretación del proyecto de ciudad progresista que llevaron a cabo las élites tulueñas entre 1910 y 1948. Para ello se revisa la manera cómo se impuso un modelo de ciudad que buscaba “paliar el atraso”, con la intención de fomentar el desarrollo agropecuario y comercial, construir una infraestructura urbana moderna y cómoda, embellecer la ciudad, imponer condiciones de higiene y salubridad, así como transformar las prácticas “incivilizadas” de sus habitantes. Esto mediante el análisis de las categorías históricas de civilización, desarrollo y progreso que se discutieron en el periodo estudiado, y la revisión de las actas y acuerdos del Concejo Municipal, escrituras notariales, informes oficiales y la prensa local.

The cultivation of lettuce in a hydroponic system is an alternative to optimize the production. Lettuce is an important food, being one of the most consumed vegetables in Brazil. The objective of this study was to evaluate the agronomic behavior of commercial cultivars of lettuce under a single nutritive solution in a hydroponic system. The experiment was carried out under greenhouse conditions. The experimental design was completely randomized, with five replicates. The treatments were composed of commercial lettuce cultivars (Americana Great Lakes, Rafaela-Americana, and Simpson Black Seed). At the time of harvest, the following parameters were evaluated: number of leaves, length of leaves and roots, fresh mass of shoot and root, and stem diameter. The collected data were submitted to an ANOVA. The cv. Rafaela-Americana presented higher leaf length. The evaluated cultivars did not present significant differences in the number of leaves, aerial green mass, green root mass, root length, and stem diameter. The cultivars showed similar variations in the number of leaves, aerial green mass, green root mass, root length, and stem diameter. The cultivar Rafaela-Americana presented a superior performance in the development of leaf length regarding the other cultivars.

The objective of this research was to evaluate genotypes of iron- and zinc-enriched common beans during breeding in producers’ farms. Yield, disease reaction, and commercial grain characteristics were evaluated to achieve this objective. In three locations of Antioquia (Rionegro, Jardín, and Betulia), seven bush beans and eight climbing bean genotypes were planted. A randomized complete block design with four replications was used in each location. There were significant differences between the bush and climbing bean genotypes that were evaluated. The highest yields, in all locations, were for the biofortified bean NUA 45 and the control variety Uribe Rosado, followed by the CAL 96 and AFR 612 genotypes. For the climbing beans, the highest yields were found in the G2333 genotypes, being this treatment equal to the MAC 27, a bean that is adapted to mid-climate and altitudes. The MAC 27 material is presented as a promising variety because of its high yields and tolerance to diseases, mainly anthracnose.

Rumen content is a waste produced in slaughterhouses. This type of solid waste can cause bad odor and atmospheric pollution if discharged directly into the environment. Additionally, it may spread disease due to the nesting vectors, and the resulting leachate can lead to groundwater contamination. The objective of this study was to determine the suitability of rumen content, waste generated in the slaughterhouse of Villapinzón (Cundinamarca), as raw material for biological transformation into vermicompost at the Fertisoluciones facilities. The characteristics of the rumen content were analyzed, and during the transformation process, three volumetric capacities (T1: 5.94 m3, T2: 23.01 m3, and T3: 16.74 m3) of compost bed were evaluated for 105 days. Through a principal component analysis, the data was reduced in two dimensions that explained 65.8% of the total variance; the first component related to the number of juvenile individuals, high pH, low moisture and temperature; and the second component related to numbers of adults individuals and high temperatures. The earthworm growth rate was determined by the food quality, as well as by bed size. Microbiological and physicochemical analyses were performed on the resulting vermicompost, demonstrating that the transformation process of rumen material into organic fertilizer, performed in Fertisoluciones facilities, fulfills the parameters required by the NTC5167 standard. This study showing the possibility of using a slaughterhouse’s solid waste and convert it into a valuable product to an industrial scale.

The adoption of adequate technologies is essential to improve the performance of different kinds of companies. Although there is literature related to the adoption of technology in dairy agribusiness in developed countries, information about it is scarce in developing countries. The objective of this study was to explore the factors associated with the adoption of technology by dairy agribusiness. A structural analysis was conducted to evaluate the relationships between the internal variables of Antioquia province farms, Colombia, and their technology adoption process. This process was explained by two factors: production-related variables and management-dependent traits. The variables resulting in the greatest impact were pasture improvement, genetics, administration, and technical procedures.
¿Es posible un abordaje fenomenológico del efecto placebo? Los alcances del esquema corporal en Merleau-Ponty
Authors: Libonati Fernando
Published: May 2020

Se comparan críticamente las teorías del condicionamiento y la expectativa. Luego se retoma la propuesta de Oron Frenkel (2008) a fin de juzgar si la noción de intencionalidad motriz permite establecer un marco teórico superador de las deficiencias de dichas teorías. Finalmente se analiza la noción de forma y los órdenes físico, vital y humano, propuestos en La Estructura del Comportamiento (1976), como abordajes alternativos. Como conclusión se destaca el valor de la experiencia del paciente en los ensayos y se plantea la posibilidad de redefinir la noción tradicional de conciencia entendida como formación de representaciones y juicios.
