Authors: Zhou Rui
Published: April 2021

Abstract: In the past, peer nomination method was mainly used to measure children’s peer relationship. Each child in the class was divided into five different grades, from popular to unpopular. This research studies peer relationship from the perspective of social network, and conducts social network analysis (SNA) on the basis of peer nomination. First, the data of children’s nomination and nominees are obtained by peer nomination method, then the matrix is made by Excel, and finally the social network analysis software UCINET is introduced for analysis. This method can analyze the centrality and density of children’s peer relationship from the perspective of individual and group, and express each child’s peer relationship in the form of the graph. In this way, we can further explore the characteristics, structure and influencing factors of children’s peer relationship, and put forward feasible suggestions to promote the development of children’s peer relationship.

Analysis of the Pros and Cons of Students' Online Courses during the Epidemic and the Prospects for the Development of English Online Platform in Secondary Vocational School
Authors: Huang Qiuyu
Published: April 2021

Facing the severe epidemic situation, China's education department has put forward an online teaching emergency plan of "Stopping going to school while keeping teaching online", so that many students in secondary vocational school can avoid close contact back to school and protect their lives and health. At the same time, it guarantees the teaching progress in the special period. Teachers in secondary vocational school prefer to choose DingTalk software to develop online teaching models. In the teaching of the vocational English network platform, online teaching is a reform of the teaching form based on information technology and the Internet. Teachers can use the DingTalk platform to interact with students, so that the online teaching method meets the individual needs of students. It takes good account of students with different English foundations and levels, and greatly stimulates students' interest in learning. This paper analyzes the advantages and disadvantages of online teaching and explores the online teaching model.

Bali cattle are superior meat producers, but they are susceptible to Jembrana disease. The injection of the crude vaccine was considered ineffective, so the env-su gene was selected to express the Jembrana Surface Unit (JSU) protein as a candidate for the Jembrana vaccine. This study aimed to analyze the potential of the JSU protein as a candidate for the Jembrana vaccine and analyze the increase in the env-su gene expression which codon has been optimized in silico. Vaccine design was carried out through in silico including the selection of the SU protein sequences of the genus Lentivirus and sequence alignment of UniProt. The construction phylogeny tree of SU protein using MEGA-X program, optimization of env-su gene codon with preference codon Esherichia coli str. K-12 substr. MG1655 using Optimizer. The optimized env-su gene was inserted into the plasmid pET-21a (+) using GenScript. The result of sequence alignment showed that there is no SU protein that has a percent identity value of more than 30% with JSU protein. The SU JDV and BIV proteins are monophyletic groups and have a percent identity of 20.57%. Codon optimization showed an increase in CAI by 1,000 and GC 54.5%, and a decrease in ENc to 22 and AT 45.5%. EcoR1 and HindIII can recognize the gene target and MCS cut regions on the plasmid so that the env-su gene can be inserted into the pET-21a (+) plasmid. The JSU protein has the potential to be a candidate for the Jembrana vaccine, but it needs further research in vitro and in vivo.
Uplatnění pozdní filozofie L. Wittgensteina v myšlení C. Geertze
Authors: Vejnbender Kristina
Published: April 2021

Širším tématem tohoto článku je otázka kulturní relativity v metodologii antropologie a sociálních věd. Cílem textu je popsat anti-anti-relativistický postoj antropologa Clifforda Geertze, v němž se odráží jeho interpretace pozdního díla L. Wittgensteina a jeho pojmu „životní forma“. Geertzův anti-anti-relativismus je výsledkem odmítnutí zaujmout pozici relativisty nebo etnocentristy, a to z několika důvodů. Hlavním problémem obou táborů je podle něj mylná představa kultury jako nedynamického a uzavřeného celku, která vyplývá z filozofické představy „ideálních“ pojmů. Taková představa je podle něj zvlášť neudržitelná v dnešním globalizovaném propojeném světě. Geertz taktéž upozorňuje na dynamický způsob formování identity (subjektu nebo kultury) prostřednictvím setkání se s cizím. Životní forma je pro Geertze metodologický nástroj, který umožňuje vyhnout se rozhodování mezi relativismem nebo anti-relativismem a který naopak poskytuje dynamickou střední cestu, jejíž pomocí jde zkoumat vzájemné prolínání identit kultur a sociálních skupin.

Published: April 2021

La fiebre y la neutropenia es la complicación más común en el tratamiento del cáncer infantil. Este tipo de complicación se dispone de una serie de reglas de decisión clínica para ayudar en la identificación de fiebre y neutropenia de bajo riesgo. La evidencia emergente sugiere que las estrategias de manejo de la fiebre aguda y la neutropenia deben incluir tiempos para la recomendación de antibióticos, y las iniciativas de mejora de la calidad se han centrado en eliminar las barreras para la administración temprana de antibióticos. A pesar de los aumentos notificados en la resistencia a los antimicrobianos, pocos estudios se han centrado en la predicción, prevención y tratamiento óptimo de estas infecciones y el efecto sobre la estratificación del riesgo sigue siendo desconocido. Actualmente la investigación pediátrica requiere de estudios más a fondo para ayudar a reducir parte de la heterogeneidad entre los estudios que previamente han limitado la comprensión de la evidencia a la práctica clínica con el fin de cuantificar los impactos generales de este enfoque y refinar exactamente qué niños se beneficiarán de la administración temprana de antibióticos, así como de modificaciones a los regímenes empíricos para cubrir los organismos resistentes a los antibióticos.

Published: April 2021

As savanas neotropicais estão distribuídas predominantemente no território brasileiro na forma de fitofisionomias que variam de campo cerrado a cerradão. A variabilidade na riqueza é tão marcante que menos de 15% da diversidade é mantida ao longo de sua abrangência. Para contribuir com o entendimento dos padrões de distribuição da vegetação do cerrado e com a diferenciação das comunidades ecotonais setentrionais, utilizou-se um banco de dados com 482 comunidades de cerrado sensu lato, em diferentes expressões florísticas, que acumulou 1221 espécies lenhosas. Calculou-se padrões de composições similares entre comunidades (floras areais), destacando as concentrações florísticas setentrionais, e evidenciou-se elevado grau de β-diversidade mediante a formação de nove floras sinareais. Tais níveis de rotatividade atestam que numerosas unidades de conservação em diferentes regiões são necessárias para proteger toda a diversidade de espécies, fisionomias e funcionalidades dos cerrados. Os resultados fornecem uma atualização e complementação científica na qual os tomadores de decisão nacionais podem contextualizar o significado mesológico dos cerrados brasileiro como condutores ambientais conectados a um sistema em maior escala. Biogeographic connections of Brazilian savannas: partition of marginal and disjunct diversity and conservation of northern ecotonal tropics in a biodiversity hotspot A B S T R A C TThe neotropical savannas are distributed predominantly in the Brazilian territory in the form of phytophysiognomies that vary from Campo limpo of Cerrado to Cerradão. The variability in richness is so remarkable that less than 15% of diversity is maintained throughout its range. To contribute to the understanding of the distribution patterns of the Cerrado vegetation and to the differentiation of northern ecotonal communities, a database of 482 communities of Cerrado sensu lato, in different floristic expressions, that accumulated 1.221 woody species was used. Similar composition patterns were calculated between communities (“areal” floras, typical of each area), highlighting the northern floristic concentrations, and a high degree of β-diversity was evidenced by the formation of nine synareal floras. These levels of turnover attest that numerous protected areas in different regions are necessary to protect all species diversity, physiognomies and functionalities of the cerrados. The results provide an update and scientific complementation in which national decision makers can contextualize the mesological meaning of Brazilian cerrados as environmental conductors connected to a larger scale system.Keywords: Cerrado, beta diversity, phytogeography, ecotone, synareal flora, marginal and disjunct savannas

A erosão costeira ocorre em várias partes do mundo. Ela, por vezes, destrói equipamentos e casas próximas da linha de costa causando prejuízos econômicos. No Estado do Ceará existem trechos que estão retrogradando, exemplo clássico é da área próxima do Porto do Mucuripe (Fortaleza). Diante do exposto, o objetivo deste estudo foi analisar a evolução da linha de costa de todo o Estado do Ceará, dentro da escala temporal de 1984 a 2018. Para alcançar esse objetivo foram realizados o processamento digital de imagens de satélite, confecção de mapas de variação da linha de costa e quantificação das áreas de progradação e retrogradação. Em termos matemáticos, na zona costeira do Ceará houve equilíbrio dinâmico entre os processos de acreção e erosão, contudo, existem alguns hotspots de erosão nos diferentes setores do litoral. Há a necessidade de monitoramento contínuo da zona costeira em diferentes escalas espaciais e temporais para melhor compreensão do comportamento costeiro, bem como políticas que inibam a ocupação deletéria a essa região. Shoreline variation in Ceará coastal zone (1984-2018) A B S T R A C TCoastal erosion occurs in several parts of the world. Sometimes, it destroys structures close to the shoreline causing economic damage. In the state of Ceará, Brazil, there are stretches with retrogradation. A classic example is from the area near the Mucuripe harbor (Fortaleza). From this context, the objective of this paper was to analyze the evolution of the State of Ceará shoreline between 1984 and 2018. To achieve this objective, the digital processing of satellite images was performed, developing maps of shoreline variation and quantification of progradation and retrogradation areas. In mathematical terms, at the coastal zone of Ceará there was a dynamic balance between the processes of accretion and erosion. However, there are some erosion hotspots in different sectors of the state shoreline. There is a need for continuous monitoring of the coastal zone in different spatial and temporal scales to better understand coastal behavior, as well as policies that inhibit the deleterious occupation of this region.Keywords: Coastal zone; Monitoring; Coastal Erosion.

Published: April 2021

El presente artículo brinda una visión de la amenaza percibida y el prejuicio que los habitantes de la zona metropolitana del valle de México expresan con relación a la migración centroamericana indocumentada en tránsito por México. Para tal fin se desarrolló e implemento un instrumento derivado de la Teoría del prejuicio sutil y manifiesto (Pettigrew y Meertens, 1995) y la Teoría de la amenaza integrada (Stephan y Stephan, 2000). Los resultados apoyan a que existen diferencias según el nivel educativo, la ocupación de los participantes, y la calidad de contacto con los migrantes. Se concluye que los habitantes de la ZMVM presentan bajos niveles de prejuicio y percepción de amenaza en general.
Forasteros, prójimos y víctimas. Figuras discursivas de la solidaridad y migración centroamericana en México
Authors: Parrini Roses Rodrigo , Alquisiras Terrones Luisa , Nocedal Rojas Emilio
Published: April 2021

Se identifican tres figuras discursivas que emergen en las prácticas solidarias que realizan diversos actores con el colectivo de migrantes centroamericanos/as que transitan por México: forastero, prójimo y víctima. Ellas condensan un proceso institucional, pero también discursivo, en el que la solidaridad con los migrantes se desplaza hacia el campo de lo que Didier Fassin denomina razón humanitaria. El análisis crítico de ese desplazamiento permite comprender cómo se constituyeron redes de atención a lo largo del país, pero también la heterogeneidad práctica y discursiva de las formas de solidaridad vigentes hoy en las rutas migratorias. Partimos de los materiales de una investigación multisituada de corte etnográfico –más de cien entrevistas y sesiones de observación participante– para indagar en la forma en que son significados los sujetos migrantes.

Hans Blumenberg, una concepción retórica de la política
Authors: Cruz Revueltas Juan Cristóbal
Published: April 2021

A pesar de constituir una de las cimas de la filosofía de la segunda parte del siglo XX, la obra de Hans Blumenberg sigue siendo poco conocida en México y en América latina. En el presente trabajo buscaremos demostrar que, si bien Blumenberg no es un filósofo político en sentido estricto, ello no impide identificar –a partir de nociones clave como distanciación, mito, politeísmo y retórica– un pensamiento político sólido y coherente con el conjunto de su obra. Por lo demás, la obra de Blumenberg constituye una clave y una vía de acceso para la comprensión de las tensiones intelectuales que vivió la cultura de la República Federal Alemana durante la segunda parte del siglo XX.
Algunas consideraciones sobre la disciplina del caso fortuito en el ordenamiento indiano
Authors: De Nardi Loris
Published: April 2021

Desde las fuentes romanas, recibidas en el Corpus Iuris Civilis, hasta llegar a las codificaciones decimonónicas, el caso fortuito resultó central tanto en el derecho público que en el privado. El estudio de las recopilaciones castellanas e indiana y del CapítuloXIX de los Comentarios a las ordenanzas de minas, publicados por Francisco Xavier de Gamboa, en 1761, permitirá subrayar como en el ordenamiento indiano, aún en las últimas décadas del Siglo XVIII, se recurriera exclusivamente a las Siete Partidas para disciplinar esta importante categoría jurídica.
Support local: Public libraries and local authors
Authors: Wiebe Rynnelle
Published: April 2021

In 2020 we have experienced movements to support local creators, restaurants, and businesses; how can the library community support local authors? This extended abstract discusses research conducted about how public libraries support local authors, with a focus on how these works are included in library collections and made findable to community members. Twelve public libraries from British Columbia, Alberta, and Saskatchewan were selected for analysis of collection policies and item metadata. Qualitative content analysis is used to code collection policies, and systemic analysis of item metadata is used to understand methods of identifying locally-authored items. The results of this research indicate that collection policies provide both opportunities and barriers for including locally-authored items and there is a lack of consistent methods for identifying items as locally-authored within item metadata. Some of these barriers can be attributed to the challenge of identifying and defining “local authorship”. This extended abstract will conclude with recommendations for how libraries can modify collection policies and methods of identifying items as locally-authored in order to support local authors and make these items more accessible to the community.

Analysis of Turbulence on Cylinder with Additional Fairing with Free Surface
Authors: Chen Siqin , Li Xiaomin
Published: April 2021

In this study, two dimensional unsteady flows of cylinder and cylinder with additional fairing close to a free surface were numerically investigated. The governing momentum equations were solved by using the Semi Implicit Method for Pressure Linked Equations(SIMPLE). The Volume of Fluid(VOF) method applied to simulate a free surface. Non- uniform grid structures were used in the simulation with denser grids near the cylinder. Under the conditions of Reynolds number 150624, 271123, 210874 and 331373, the cylinders were simulated with different depths of invasion. It was shown that the flow characteristics were influenced by submergence depth and Reynolds numbers. When the cylinder close to the free surface, the drag coefficient, lift coefficient and Strouhal numbers will increase due to the effect of free liquid surface on vortex shedding. With additional fairing, can effectively reduce the influence of the free surface on the drag coefficient. Fairing will reduce lift coefficient at high Reynolds numbers, but increase lift coefficient when Reynolds numbers are small. Fairing can effectively reduce Strouhal numbers, thus can well suppress the vortex induced vibration
Remote working in the period of the COVİD-19

Published: April 2021

Working remotely was an option for the employees before the Covid-19 pandemic. However, it's become a new working format and compulsory for the white collars to work at home. Even if it seems attractive at first look, the new format of working style actually has caused lots of problems especially on employees' mental health. The social life, private comfort zone, and working environment of the workers have mixed with each other and the equilibrium among them which gave certainty and predictability is totally broken now. Actually, the employees started to search for a new normal and balance in the pandemic. I am planning to focus on occupational stress that popped up in the pandemic with regard remote working. It is structured to focus on the problems which are the broken balance between work and family, the problem of workload and over-working, the future ambiguity about the career, and miscommunication, to analyze how these problems bring out mental health disorder with giving experiments done by other researchers. In the final part, I will try to give some suggestions on how to get over it or reduce it.

Legume green manure is extensively planted to improve soil fertility in crop field. However, the application of legume in Eucalyptus plantation is still limited and depends on site specific and species. Therefore, the objective of this study was to determine the effects of green manure interplantation on soil fertility and plant growth of Eucalyptus plantation in a short term. A field experiment of one year was established to investigate the green manure growth, forest soil nutrients and Eucalyptus plant growth inter-planted with two legume species (Tephrosia candida, TC and Sesbania cannabina, SC) at south subtropical China. Legumes were inter-planted in linear among the tree space of Eucalyptus stand. Result showed that the green manure inter-plantation increased soil organic matter by 9.66% of TC and 18.44% of SC. Soil available nitrogen, phosphorus and potassium were improved significantly by the legume treatments as well. The increment of height and diameter at breast height of Eucalyptus during the experiment was significant in legume treatments. Thus, the timber volume increment was improved significantly by 46.81% of TC and 35.47% of SC compared with the control treatment. Therefore, the inter-plantation of legume green manure under the Eucalyptus plantation is effective to improve soil fertility and tree growth. Such a measure is potential and referenced for the sustainable forest management.

Food insecurity in most dry regions in Zimbabwe has taught many people a lesson of using non timber forest products (NTFPs) to reduce food insecurity and improve livelihoods as well as poverty alleviation. The aim of the study was to evaluate the potential contribution of non-timber forest products to smallholder farmers in arid and semi-arid regions. The research was carried out as a survey and data was collected using interviews, questionnaires and focus group discussion. Data was analysed for descriptive statistics using IBM SPSS version 25. Results indicated that 64 % were females and 36 % were males with the majority of participants being married (57.6 %) with only 8.8 % being widowed. Results show that all respondents (100%) indicated that they obtain fruits from the forests as a major source of food during winter and rain season. Vegetables (84.2 %), thatching grass (80.8%) and edible worms (62.5 %) were also major non-timber forest products obtained from the forests by participants. All participants (100%) indicated that income generation, firewood and source of heat for brick moulding were major benefits they obtain from forest with vegetables (74.2 %), brooms (91.7 %) and improved nutrition (85.0 %) being regarded as other important benefits enjoyed by local people from forests. Afforestation and reforestation were regarded as major sustainable forest management practices by all (100%) participants with agroforestry being indicated by only 12.5 % since people had no knowledge about it. NTFPs has capacity of improving food security, human livelihoods and alleviate poverty. People are encouraged to harvest NTFPs sustainably to allow future use. Use of agroforestry can be a best way for managing forests sustainably, improve food security, crop yield, poverty alleviation and climate change mitigation.

The COVID-19 pandemic provides the first widespread bear market conditions since the inception of cryptocurrencies. We test the haven properties of cryptocurrencies for African stocks and commodity markets in a pandemic implementing the frequency domain spillover index. Data spans 11th August 2015 to 28th August 2020 at a daily frequency. Findings show weak interconnectedness across markets suggesting non-contagion risk and that cryptocurrency are safe havens for African stocks and commodity indices from the medium-term. We find the major transmitters of spillover effects across markets to be time-varying and heterogeneous. This study provides significant risk diversification benefits for policymakers and investors in the African financial markets.

Introduction: There are various applications and health information systems which have been developed to promote the effective retrieval of patient information, statistics, research, and education. Therefore, there is a need to design them in consistency with scientific principles of usability. To this end, the usability of hospital information sub-systems employed at the hospitals of Ahvaz were compared using heuristic evaluation method. The objective of the study was to assess the usability of hospital information system according to heuristic evaluation.Material and Methods: Six trained evaluators, independently determined the ADT subsystem, HIM subsystem, and NIS according to Nielsen’s 10 Heuristic Principles. Since more than half of the hospitals (about 54%) employed Sib application, no specific sampling method was used. After combining the usability problems, the average severity ratings of the problems were calculated, and then the subsystems were compared.Results: The number of the usability problems of the ADT information subsystem, HIM subsystem, and NIS were 40, 39, and 37, respectively. After merging the problems, the features of “user control and freedom” with 20 cases and “flexibility and efficiency of use” with six cases had the highest and the lowest inconsistencies with usability principles. The average severity ratings of the problems also varied between 1.7 and 3.Conclusion: Heuristic evaluation method is regarded as one of the approaches appropriate to identify usability problems in health information systems. Thus, it is advisable to utilize this method to modify the design of the systems and to improve their efficiency before their implementation in order to increase user satisfaction.

Authors: BAYKAL Aslihan , TURNA Özge
Published: April 2021

In bitches, the incidence of mammary tumors is determined at %50 of all neoplasms. Most of the cases are malignant and tend to metastasize. Because of this, early diagnosis has an important value. Due to the molecular and clinical similarities of canine mammary tumors to human breast cancers, human breast cancer markers are also detectable in cases of canine mammary tumors. Generally, biomarkers provide information about criteria such as clinical diagnosis, early diagnosis, prognosis, and determination of the treatment protocol. When choosing the appropriate biomarker, it should be taken into account that it is easy to apply, has a positive correlation with tumor specificity and malignancy, and whether gives precise information about prognosis. Due to the heterogeneous nature of canine mammary tumors, an ideal biomarker has not determined yet. However, new studies have revealed the existence of many biomarkers. In this review it is given to qualified and current biomarkers can be used in dogs, including invasive and non-invasive mammary tumor biomarkers.

С помощью современных методов молекулярного моделирования показано, что реакции гидро- и метилпероксидных радикалов с одним из компонентов биомасел - p-бензилфенолом-являются экзотермичными. Как следствие, добавление p-бензилфенола в горючие смеси может приводить к его низкотемпературному цепному окислению,а значит к снижению времени и температуры воспламенения смесей.

Published: April 2021

Транспортеры органических анионов принимают участие в выведении широкого спектра отрицательно заряженных ионов лекарственных средств (ЛС) через почки. При этом возможно возникновение нефротоксических явлений, связанных с накоплением ксенобиотиков в клетках проксимальных почечных канальцев. В настоящее время нефротоксичность ЛС выявляется на доклинических этапах достаточно редко, что связано с несоответствием результатов, полученных на существующих экспериментальных моделях in vitro, с данными клинических исследований. Рассмотрена перспективная клеточная линия проксимальных почечных канальцев человека в качестве экспериментальной модели in vitro для тестирования нефротоксичности ЛС. Показано, что при транспорте субстратов ОАТ – цефипима и цефуроксима — на данной модели активация эффекторных каспаз 3 и 7 наблюдается на 2-е сутки даже при низкой концентрации препаратов.

The influence of regional stress and structural control on the shape of maar craters
Authors: Nichols Cody , Graettinger Alison
Published: April 2021

Maars are volcanic craters excavated by the interaction of magma and groundwater in subsurface phreatomagmatic explosions. Maar craters display a variety of shapes and sizes, but commonly display elongation. This paper explores the relationship between the orientation of maar elongation and regional stress indicators. The orientations of maar elongation, regional faults, and nearest neighbor lineaments containing maars were measured in seven volcanic fields: Auckland, Lamongan, Newer Volcanics Province, Pali Aike, Pinacate, San Pablo City, and Serdán Orientale. Common maar orientations were observed in several fields, and compared with faulting and nearest neighbor lineaments. It was found that the distribution of maars was commonly correlated with regional stress indicators (in lineaments), but the orientation of elongation of those maars did not always correlate with stress indicators. Maars not aligned with stress indicators were likely influenced by more local effects, including changes to the subsurface stress regime from the ongoing eruption.
