Dimensiones del clima laboral que afectan la ejecución de proyectos. Caso BID
Authors: VILLAFUERTE Santiago B. , VITERI Fernando A. , LOPEZ Hector A.
Published: May 2021

excesiva estructura burocrática, desconocimiento en la asignación, delimitación de funciones, responsabilidades de sus integrantes, desvinculaciones en el sector público, incumplimiento de normas, procesos, políticas, así como, movimientos internos de personal que provocan alteraciones en las fases preparatorias, precontractual, contractual y postcontractual; siendo el clima laboral, según Robles, Dierssen, Martínez, Herrera, Díaz, y Llorca (2005) un conjunto de características que influyen en el comportamiento de una institución y en la realización de sus procesos y proyectos que la distingue de otras; siendo éstas de permanencia relativa en el tiempo. Robbins (2009) señaló que el clima laboral genera satisfacción en el colaborador y en igual sentido fuera de él, entendiendo que una meta de alta satisfacción puede expresarse en términos, tanto de dinero, como de responsabilidad social, por tanto, si cualquier persona del equipo de gestión está motivado aportará al logro de los objetivos del Proyecto creando de esta manera una coordinación de logro de objetivos institucionales y objetivos personales.
A ATUAÇÃO DA ESCOLA NA SUBSTITUIÇÃO DO VÊNETO PELO PORTUGUÊS NAS ZONAS URBANA E RURAL DE ALFREDO CHAVES, ESPÍRITO SANTO
Authors: Peres Edenize Ponzo , Fiorin Marcio Favero
Published: May 2021

Alfredo Chaves foi um dos municípios do Espírito Santo colonizados por imigrantes italianos, sobretudo da Região do Vêneto, que ali chegaram a partir de 1877, trazendo consigo a sua cultura e a sua língua. Entretanto, os crescentes contatos entre os imigrantes e seus descendentes com os falantes de português levaram a uma expressiva diminuição dos usos das variedades vênetas. Assim, este estudo busca analisar a atuação da escola no processo de substituição do vêneto pelo português em duas comunidades de Alfredo Chaves (ES): a Sede e a comunidade rural de Santa Maria de Ibitiruí. Nossos dados foram obtidos por meio entrevistas com descendentes de imigrantes italianos, além de (ex-)agentes escolares que residem nas duas localidades. As análises, feitas com base na teoria do Contato Linguístico, evidenciam que o sistema educacional atuou em favor da propagação das leis nacionalistas de Vargas e que o ensino do português ainda contribui para excluir a variação linguística nas salas de aula, culminando em situações de preconceito contra quem fala o português com influência da língua vêneta. Diante desses resultados, concluímos que se faz necessário um trabalho de apoio aos agentes escolares, por meio de formação continuada junto a eles, a fim de que a diversidade cultural e linguística seja respeitada e valorizada pela escola.
Emerging Applications on Smart Phones: The Role of Privacy Concerns and its Antecedents on Smart Phones Usage
Authors: Al-Ghaith Waleed
Published: May 2021

Many applications on smart Phones can use various sensors embedded in the mobiles to provide users’ private information. This can result in a variety of privacy issues that may lessening level of mobile apps usage. To understand this issue better the researcher identified the root causes of privacy concerns. The study proposed a model identifies the root causes of privacy concerns and perceived benefits based on our interpretation for information boundary theory. The proposed model also addresses the usage behavior and behavioral intention toward using mobile apps by using the Theory of Planned Behavior. The result shows that “Cultural values” alone explains 70% of “Perceived privacy concerns” followed by “Self-defense” which explains around 23% of “Perceived privacy concerns”, and then “Context of the situation” with 5%. Whereas, the findings show that “Perceived effectiveness of privacy policy” and “Perceived effectiveness of industry self-regulation” both are factors which have the ability to reduce individuals “Perceived privacy concerns” by 9% and 8% respectively.
Comparison Analysis of Facebook’s Prophet, Amazon’s DeepAR+ and CNN-QR Algorithms for Successful Real-World Sales Forecasting
Authors: Žunić Emir , Korjenić Kemal , Delalić Sead , Šubara Zlatko
Published: May 2021

By successfully solving the problem of forecasting, the processes in the work of various companies are optimized and savings are achieved. In this process, the analysis of time series data is of particular importance. Since the creation of Facebook’s Prophet, and Amazon’s DeepAR+ and CNN-QR forecasting models, algorithms have attracted a great deal of attention. The paper presents the application and comparison of the above algorithms for sales forecasting in distribution companies. A detailed comparison of the performance of algorithms over real data with different lengths of sales history was made. The results show that Prophet gives better results for items with a longer history and frequent sales, while Amazon’s algorithms show superiority for items without a long history and items that are rarely sold.

Published: May 2021

A continuous monitoring of the physical strength and mobility of elderly people is important for maintaining their health and treating diseases at an early stage. However, frequent screenings by physicians are exceeding the logistic capacities. An alternate approach is the automatic and unobtrusive collection of functional measures by ambient sensors. In the current publication, we show the correlation among data of ambient motion sensors and the well-established mobility assessments Short-PhysicalPerformance-Battery, Tinetti and Timed Up & Go. We use the average number of motion sensor events as activity measure for correlation with the assessment scores. The evaluation on a real-world dataset shows a moderate to strong correlation with the scores of standardised geriatrics physical assessments.
Applicability of Overlay Non-Delay Tolerant Position-Based Protocols in Highways and Urban Environments for VANET
Authors: Al Shugran Mahmoud Ali
Published: May 2021

Vehicular Ad hoc Networks (VANETs) is new sort in wireless ad-hoc networks. Vehicle-to-Vehicle (V2V) communication is one of the main communication paradigms that provide a level of safety and convenience to drivers and passengers on the road. In such environment, routing data packet is challenging due to frequently changed of network topology because of highly dynamic nature of vehicles. Thus, routing in VANETs in require for efficient protocols that guarantee message transmission among vehicles. Numerous routing protocols and algorithms have been proposed or enhanced to solve the aforementioned problems. Many position based routing protocols have been developed for routing messages that have been identified to be appropriate for VANETs. This work explores the performances of selected unicast non-delay tolerant overlay position-based routing protocols. The evaluation has been conducted in highway and urban environment in two different scenarios. The evaluation metrics that are used are Packet Delivery Ratio (PDR), Void Problem Occurrence (VPO), and Average Hop Count (AHC).
Using the technology adoption model for the modelling of teachers' technology awareness factors
Authors:   , Ntshakala Tholokuhle Thobile
Published: May 2021

Information and Communication Technologies (ICTs) are omnipresent in the world and that includes the worlds of sport, education and physical education (PE). However, there seems to be a scarcity of PE teachers who are well aware of the benefits of the use of ICTs in PE. The aim of this study is therefore to design a model of the factors affecting the perceived awareness of PE teachers of the benefits of the use of ICTs in PE. This aim is sub-divided into four research objectives: (a) to select relevant technology adoption theories for the design of a model of the factors affecting the perceived awareness of PE teachers of the benefits of the use of ICTs in PE; (b) to design a conceptual model of the factors affecting the perceived awareness of PE teachers of the benefits of the use of ICTs in PE; (c) to empirically test the above mentioned conceptual model; and, (d) to make appropriate recommendations from the knowledge of the factors affecting the perceived awareness of PE teachers of the benefits of the use of ICTs in PE. Objectives a, b, and d were accomplished through the review of existing literature on the factors affecting the adoption of e-learning by teachers. As for objective c, it was achieved through the survey of 73 teachers from Camperdown schools in the UMgungundlovu District Municipality of the KwaZulu-Natal province of South Africa. Here is a summary of how these objectives have been met in this study: (a) The Technology Adoption Model (TAM) serves as the theoretical model behind the choice of the research variables of this study; (b) This study hypothesizes that PE teachers’ perceived awareness of the benefits of the use of ICTs is affected by the following variables: demographics, performance expectancy, social influence, and computer attitude; (c) The survey conducted by this study confirms that PE teachers’ perceived awareness of the benefits of the use of ICTs is affected by their performance expectancy, and by three teachers’ demographics (computer usage, gender, and age group); (d) This study calls for more research on the factors affecting teachers’ awareness of the benefits of ICTs, since the study failed to find enough literature on this topic.

Urban aerosol chemistry at a land-water transition site during summer – Part 1: Impact of agricultural and industrial ammonia emissions
Authors: Balasus Nicholas , Battaglia Michael A. , Ball Katherine , Caicedo Vanessa , Delgado Ruben , Carlton Annmarie G. , Hennigan Christopher J.
Published: May 2021

Abstract. This study characterizes the impact of the Chesapeake Bay and associated meteorological phenomena on aerosol chemistry during the second Ozone Water-Land Environmental Transition Study (OWLETS-2) field campaign during summer 2018. Measurements of inorganic PM2.5 composition, gas-phase ammonia (NH3), and an array of meteorological parameters were undertaken at Hart-Miller Island (HMI), a land-water transition site just east of downtown Baltimore on the Chesapeake Bay. The observations at HMI were characterized by abnormally high NH3 concentrations (maximum of 19.3 μg m-3, average of 3.83 μg m-3), which were more than a factor of three higher than NH3 levels measured at the closest Atmospheric Ammonia Network (AMoN) site (approximately 45 km away). While sulfate concentrations at HMI agreed quite well with those measured at a regulatory monitoring station 45 km away, aerosol ammonium and nitrate concentrations were significantly higher, due to the ammonia-rich conditions that resulted from the elevated NH3. The high NH3 concentrations were largely due to regional agricultural emissions, including dairy farms in southeastern Pennsylvania and poultry operations in the Delmarva Peninsula (Delaware-Maryland-Virginia). Reduced NH3 deposition during transport over the Chesapeake Bay likely contributed to enhanced concentrations at HMI compared to the more inland AMoN site. Several peak NH3 events were recorded, including the maximum NH3 observed during OWLETS-2, that appear to originate from a cluster of industrial sources near downtown Baltimore. Such events were all associated with nighttime emissions and advection to HMI under low 15 wind speeds (< 1 m s-1) and stable atmospheric conditions. Our results demonstrate the importance of industrial sources, including several that are not represented in the emissions inventory, on urban air quality. Together with our companion paper, which examines aerosol liquid water and pH during OWLETS-2, we highlight unique processes affecting urban air quality of coastal cities that are distinct from continental locations.
Is our dynamical understanding of the circulation changes associated with the Antarctic ozone hole sensitive to the choice of reanalysis dataset?
Authors: Orr Andrew , Lu Hua , Martineau Patrick , Gerber Edwin P. , Marshall Gareth J. , Bracegirdle Thomas J.
Published: May 2021

Abstract. This study quantifies differences among four widely used
atmospheric reanalysis datasets (ERA5, JRA-55, MERRA-2, and CFSR) in their
representation of the dynamical changes induced by springtime polar
stratospheric ozone depletion in the Southern Hemisphere from 1980 to 2001.
The intercomparison is undertaken as part of the SPARC
(Stratosphere–troposphere Processes and their Role in Climate) Reanalysis
Intercomparison Project (S-RIP). The reanalyses are generally in good
agreement in their representation of the strengthening of the lower
stratospheric polar vortex during the austral spring–summer season,
associated with reduced radiative heating due to ozone loss, as well as the
descent of anomalously strong westerly winds into the troposphere during
summer and the subsequent poleward displacement and intensification of the
polar front jet. Differences in the trends in zonal wind between the
reanalyses are generally small compared to the mean trends. The exception is
CFSR, which exhibits greater disagreement compared to the other three
reanalysis datasets, with stronger westerly winds in the lower stratosphere
in spring and a larger poleward displacement of the tropospheric westerly
jet in summer. The dynamical changes associated with the ozone hole are examined by
investigating the momentum budget and then the eddy heat and momentum
fluxes in terms of planetary- and synoptic-scale Rossby wave contributions.
The dynamical changes are consistently represented across the reanalyses
and support our dynamical understanding of the response of the coupled
stratosphere–troposphere system to the ozone hole. Although our results
suggest a high degree of consistency across the four reanalysis datasets in
the representation of these dynamical changes, there are larger differences
in the wave forcing, residual circulation, and eddy propagation changes compared to the zonal wind trends. In particular, there is a noticeable
disparity in these trends in CFSR compared to the other three reanalyses,
while the best agreement is found between ERA5 and JRA-55. Greater
uncertainty in the components of the momentum budget, as opposed to mean
circulation, suggests that the zonal wind is better constrained by the
assimilation of observations compared to the wave forcing, residual
circulation, and eddy momentum and heat fluxes, which are more dependent on
the model-based forecasts that can differ between reanalyses. Looking
forward, however, these findings give us confidence that reanalysis datasets
can be used to assess changes associated with the ongoing recovery of
stratospheric ozone.
Future changes in Beijing haze events under different anthropogenic aerosol emission scenarios

Published: May 2021

Abstract. Air pollution is a major issue in China and one of the
largest threats to public health. We investigated future changes in
atmospheric circulation patterns associated with haze events in the Beijing
region and the severity of haze events during these circulation conditions from 2015 to 2049 under two different aerosol scenarios: a maximum
technically feasible aerosol reduction (MTFR) and a current legislation
aerosol scenario (CLE). In both cases greenhouse gas emissions follow the
Representative Concentration Pathway 4.5 (RCP4.5). Under RCP4.5 with CLE
aerosol the frequency of circulation patterns associated with haze events
increases due to a weakening of the East Asian winter monsoon via increased
sea level pressure over the North Pacific. The rapid reduction in
anthropogenic aerosol and precursor emissions in MTFR further increases the
frequency of circulation patterns associated with haze events, due to
further increases in the sea level pressure over the North Pacific and a
reduction in the intensity of the Siberian high. Even with the aggressive
aerosol reductions in MTFR periods of poor visibility, represented by above-normal aerosol optical depth (AOD), still occur in conjunction with
haze-favorable atmospheric circulation. However, the winter mean intensity
of poor visibility decreases in MTFR, so that haze events are less dangerous
in this scenario by 2050 compared to CLE and relative to the current
baseline. This study reveals the competing effects of aerosol emission
reductions on future haze events through their direct contribution to
pollutant source and their influence on the atmospheric circulation. A
compound consideration of these two impacts should be taken in future policy
making.
Modeling the marine chromium cycle: New constraints on global-scale processes
Authors: Pöppelmeier Frerk , Janssen David J. , Jaccard Samuel L. , Stocker Thomas F.
Published: May 2021

Abstract. Chromium (Cr) and its isotopes hold great promise as tracer of past oxygenation and marine biological activity due to the different chemical properties of its two main oxidation states, Cr(III) and Cr(VI), and the associated fractionation during redox transformations. However, to date the Cr cycle remains poorly constrained due to insufficient knowledge about sources and sinks and the influence of biological activity on redox reactions. We therefore implemented the two oxidation states of Cr in the Bern3D Earth system model of intermediate complexity, in order to gain an improved understanding on the mechanisms that modulate the spatial distribution of Cr in the ocean. Due to the computational efficiency of the Bern3D model we are able to explore and constrain the range of a wide array of parameters. Our model simulates vertical, meridional, and inter-basin Cr concentration gradients in good agreement with observations. We find a mean ocean residence time of Cr between 5 and 8 kyr, and a benthic flux, emanating from all sediment surfaces, of of 0.1–0.2 nmol cm-2 yr-1, both in the range of previous estimates. We further explore the origin of regional model-data mismatches through a number of sensitivity experiments. These indicate that the benthic Cr flux may be substantially lower in the Arctic than elsewhere. In addition, we find that a refined representation of oxygen minimum zones and their Cr redox potential yields Cr(III) concentrations and Cr removal rates in much improved agreement with observational data.
The diurnal Energy Balance Model (dEBM): a convenient surface mass balance solution for ice sheets in Earth system modeling
Authors: Krebs-Kanzow Uta , Gierz Paul , Rodehacke Christian B. , Xu Shan , Yang Hu , Lohmann Gerrit
Published: May 2021

Abstract. The surface mass balance scheme dEBM (diurnal Energy Balance Model) provides a novel interface between the atmosphere and land ice for Earth system modeling, which is based on the energy balance of glaciated surfaces. In contrast to empirical schemes, dEBM accounts for changes in the Earth’s orbit and atmospheric composition. The scheme only requires monthly atmospheric forcing (precipitation, temperature, shortwave and longwave radiation, and cloud cover). It is also computationally inexpensive, which makes it particularly suitable to investigate the ice sheets' response to long-term climate change.
After calibration and validation, we analyze the surface mass balance of the Greenland Ice Sheet (GrIS) based on climate simulations representing two warm climate states: a simulation of the mid-Holocene (approximately 6000 years before present) and a climate projection based on an extreme emission scenario which extends to the year 2100.
The former period features an intensified summer insolation while the 21st century is characterized by reduced outgoing longwave radiation. Specifically, we investigate whether the temperature–melt relationship, as used in empirical temperature-index methods, remains stable under changing insolation and atmospheric composition. Our results indicate that the temperature–melt relation is sensitive to changes in insolation on orbital timescales but remains mostly invariant under the projected warming climate of the 21st century.
Heeding the Call for Social Justice: How a CPED Ed.D. Program Illuminates the Instructional Intersection Between COVID-19 and the Black Lives Matter Movement
Authors: Nasr Nancy
Published: May 2021

The intersection of the COVID-19 pandemic and the BLM movement led to a historic moment for American society. Illness, death, and civil unrest provided a shared historical experience for all Americans, and provided an opportunity for educators to capitalize on the multitude of teachable moments these historical events provided. For educators, like myself, who were the product of CPED Ed.D. programs that emphasized social justice in education, the historical events of COVID-19 and the BLM movement were immediately recognized as an opportunity to bring social justice to the forefront in the online classroom. The purpose of this manuscript is to reflect on the impact that my CPED Ed.D. experience had on my awareness of social justice in education and how this awareness translates to online learning opportunities in light of the COVID-19 pandemic to provide students with experiences that emphasize the need to understand and overcome social injustices, through science.
Adult learners, remote learning, and the COVID pandemic: Restructuring educational doctorate courses in crisis
Authors: DeMartino Linsay
Published: May 2021

This essay serves as the narrative of an early career Assistant Professor as they recall their struggles, vulnerabilities, and insecurities while navigating the need to shift their educational leadership doctoral students to emergency remote learning amid a global pandemic. Using the foundations of transformational experiences for adult learners, the need to sustain the students’ communities of practice, and positive school leadership, the author develops and executes their action plan to meet the needs of their adult learners and support them in the online environment during the COVID-19 crisis. By applying this framework as practicing EdD scholars, we serve as a model for future directions in the teaching spaces of the Education Doctorate by bridging the gap between theory and practice in our higher education teaching spaces.
An Unexpected Affordance of Program Design for Dissertation Writing During COVID-19: The Embedded Dissertation
Authors: Capello Sarah , Gyimah-Concepcion Mellissa , Billimack Victoria Vandover
Published: May 2021

Purpose: This paper describes how an embedded dissertation program design feature supported two cohorts of EdD dissertators and helped them make consistent progress toward and eventually complete their dissertation milestones during the COVID-19 pandemic. Specifically, we detail the work, challenges, and results of EdD students’ efforts toward their milestones and offer perspectives on the same topics for EdD faculty who are teaching dissertation writing courses or supporting dissertators during the COVID-19 pandemic.Conceptual Argument: This paper argues that an existing program design feature, the embedded dissertation, provided unexpected affordances for EdD dissertators during the COVID-19 pandemic. Specifically, it acted as a scaffold for dissertators to make small but consistent steps forward on their dissertation milestones despite the significant challenges they faced both as practitioners and as students during the pandemic.Implications for Research: In sharing these experiences, we hope to: (a) offer a contribution to the literature on the intersection of program design and dissertation writing, (b) proffer a program design structure that was successful in moving dissertators forward during COVID-19, and (c) document the lived experiences of EdD dissertators and faculty in this unprecedented, historical moment.

The quality of the environment has an impact on all spheres of human life in the modern world and is a constant subject of scientific research. Despite a significant number of scientific publications devoted to global problems of humanity, the issues of the influence of culture on the formation of attitudes to the environment, within the framework of the modern human life world, require rethinking. The article considers the features and problem field of the processes of degradation of the biological environment in the conditions of the modern level of human culture.
FEATURES, PROBLEMS, THE CONCEPT OF MEDICAL MANAGEMENT
Authors: Shapiro Stanislav Romanovich , Abdrakhimov Vladimir Zakirovich
Published: May 2021

Analytical studies show that until now the essence of medical management has not been properly reflected in the economic and medical sciences, and therefore there is no sufficient scientific and methodological support for this type of management. The existence of a contradiction between the need for medical management and the necessary and sufficient scientific and methodological support for it has led to the relevance of the study of medical management. Medical management should study and investigate the ever-changing trends in healthcare. Medical management should take into account one of the basic unwritten laws of medicine − by accepting a patient for inpatient treatment, the hospital is fully responsible for his life and health.

La imagen de las sirenas en dos pasajes de la obra de Clemente de Alejandría: un caso de hibridismo cultural
Authors: Huerta Rodríguez Jesus Caos
Published: May 2021

En la obra de Clemente de Alejandría existen ciertos motivos temáticos que reflejan situaciones de hibridismo cultural. El caso de las sirenas constituye un ejemplo de esa realidad híbrida. Por esta razón, se aborda el análisis de dos textos donde el alejandrino cita de manera explícita a estos seres mitológicos. El primero de ellos es un pasaje de la Septuaginta (Strom. VI 50.4), el segundo es un fragmento atribuido a Eurípides. En ambos textos Clemente introduce algunas modificaciones con la intención de adecuar el texto recibido al contexto cultural desde donde realiza la lectura. Este hecho es un indicio de un permanente diálogo desde el hibridismo cultural, pues termina realizando lecturas novedosas de sus fuentes como producto de las preocupaciones temáticas de su horizonte cultural.

El papel de Sémele en los cultos dionisiacos. Una visi´ón general.
Authors: Rodríguez María Victoria Vaello
Published: May 2021

Sémele es la madre mortal de Dioniso, fulminada por el rayo de Zeus y posteriormente divinizada por su hijo como Tione. Testimonios literarios y epigráficos muestran que Sémele recibió culto en varios puntos de la Grecia clásica, como Tebas, Delfos y Ática, normalmente junto a Dioniso. Tres epígrafes procedentes de Atenas, Erquias y Miconos, fechados entre los siglos V y III a.C. son clave para señalar los vínculos entre las Leneas y los misterios de Eleusis, así como la importancia de Sémele en el origen de dicho culto. En estos testimonios son protagonistas las mujeres. En el caso del calendario de cultos de Erquias es casi segura la integración del menadismo dentro de la religión cívica, con Sémele como mediadora entre las fieles y su hijo, como parecen apoyar las imágenes vasculares. Estos precedentes serán terreno fértil para el desarrollo de misterios específicos para mujeres centrados en la muerte y apoteosis de Sémele, particularmente en Tracia, en las épocas helenística e imperial.

Com base em pesquisa empírica original com juízes, promotores, advogados de defesa e testemunhas especializadas em três tribunais penais internacionais, Writing History in International Criminal Trials, livro introduzido no presente artigo, procura entender como o direito e a história são combinados no tribunal. O testemunho histórico agora é parte integrante dos julgamentos internacionais, com promotores e equipes de defesa usando testemunhos históricos para atingir objetivos decididamente legais. No julgamento de Slobodan Milosevic, a promotoria procurou demonstrar intenção especial de cometer genocídio por referência a um animus de longa data, alimentado dentro de uma mentalidade nacionalista. Por sua parte, a defesa convocou historiadores como testemunhas para minar as acusações de responsabilidade superior e para mitigar a sentença, representando os crimes como represálias. Embora os modos legais de conhecer sejam distintos dos da história, os dois são efetivamente combinados em julgamentos internacionais de uma maneira que nos desafia a repensar a relação entre direito e história.
Entre as margens do Atlântico

Published: May 2021

Este artigo examina, a partir da perspectiva da historiografia e do direito criminal internacional, a máfia da Córsega-Marselha, a French Connection e a história de Auguste Joseph Ricord, uma daquelas figuras do narcotráfico internacional que, folheando aqui e ali em tempos e contextos muito diferentes, parece realmente vindo da caneta de um escritor que ama conspirações e tramas internacionais. O autor, através das escassas informações disponíveis na rede, tenta restaurar da forma mais detalhada possível o perfil de Ricord e de toda a rede de relacionamentos e entrelaçamentos entre ambientes do submundo, mas, no entanto, também da promiscuidade com aparelhos de segurança do mais alto nível, o que fez do narcotraficante francês uma autêntica figura de referência para o tráfico de drogas entre a Europa e as Américas durante um período de trinta anos, entre o final da década de 1940 e o início da década de 1970, quando, não sem dificuldade, foi extraditado para os Estados Unidos e lá condenado a uma longa prisão.
Colonialidade e política do esquecimento
Authors: Vinhas Wagner
Published: May 2021

O artigo busca refletir o silenciamento da intelectualidade negra brasileira. Reporto-me às estratégias para silenciar homens e mulheres negros cuja prática social consiste naquilo que denominamos por política do esquecimento e cujo mecanismo consiste em se apagar da memória das novas gerações a contribuição de autores negros e negras. É nesse sentido que o dilema da intelectualidade negra no Brasil reside na herança racista do campo intelectual brasileiro - um duplo vínculo – ordem científica e ordem social. Em discordância do que diz a teoria bourdiana, presume-se que o acúmulo de capital específico não pode justificar a ausência de autores negros e negras no campo intelectual brasileiro. Tudo leva a crer que, no Brasil, o que determina a posição no campo intelectual vai além da incorporação de um tipo de capital específico – classe, escolaridade, origem – transferido para o campo intelectual de um espaço social circundante: raça, gênero, classe.

Authors: Dragoi Alexandra , Alexandru Oana
Published: May 2021

Cancer chemotherapeutic drugs acts in different manner to kill malignant cells. Most of the anticancer drugs available in clinical practice to treat cancer patients, are natural products including whole plant extract, crude plant extracts, isolated constituents, plant –based drug formulations etc. These natural compounds have been a basis for the development of several drugs against cancer. Agents such as topotecan, taxol, vinca alkaloids (vincristine, vinblastine, vinorelbine and vindesine), are important anticancer agents in widespread clinical use. Other agents, such as combretastatin, flavopiridol, betulinic acid were shown to have anti-tumor effects in both in vitro and in vivo experiments.

In this review, we aim to make a brief description of classical plant-derived chemotherapeutics drugs and also to highlight the importance of these natural compounds in the development of new potential drugs in cancer treatment.
