Authors: Sampaio Francisco A. Costa , Jucá-Chagas Ricardo , Teixeira Paulo Marcelo M. , Boccardo Lilian
Published: April 2022

Este artigo discute o conhecimento sobre os peixes e a pesca por estudantes do povoado de Porto Alegre, localizado às margens do reservatório da Pedra, no médio rio de Contas, Bahia. O estudo foi realizado na Escola Luís Braga no período de março a agosto de 2004, contando com a participação de 93 alunos. Foi utilizado um questionário para coleta de dados com o objetivo de averiguar as concepções dos alunos sobre aspectos da biologia e ecologia dos peixes (ecologia trófica, reprodução e classificação), percepção sobre questões ambientais, aspectos da pesca local e as relações desta com os alunos. Também foram realizadas entrevistas semi-estruturadas com os professores da escola, assim como analisado o conteúdo do capítulo do livro didático adotado que aborda o assunto ‘peixes’, de forma a delinear a contribuição ao conhecimento ictiológico dos alunos. Os resultados mostraram que o conhecimento dos alunos sobre os peixes da região e sua ecologia foi adquirido pelo seu envolvimento com as atividades pesqueiras familiares. A visão fragmentária de conceitos foi detectada, principalmente no que se refere ao aspecto da reprodução dos peixes, apesar deste tópico integrar os conteúdos de zoologia e ser mencionado no livro didático analisado. Este aprendizado é de extrema relevância e sua conscientização se faz importante para a manutenção de estoques pesqueiros, bem como à conservação da diversidade de peixes dos corpos d’água da região. Deste modo, este estudo aponta para a necessidade da valorização das concepções prévias dos alunos, no ambiente escolar, visando a construção de um conhecimento mais abrangente sobre os peixes embasado no saber científico.

Published: April 2022

La importancia de un recurso depende de diversos factores tanto culturales como ecológicos. Es importante realizar este tipode estudios con la finalidad de mantener el conocimiento tradicional. Este trabajo pretende identificar la importancia cultural con base en el uso de cinco especies de artrópodos (Diaethria candrena, Periplaneta sp, Scolopendra sp., Arsenura armida., Polistes sp.) por medio de entrevistas semiestructuradas a 20 núcleos familiares de una comunidad mestiza y una Totonaca en el Municipio de Tlacuilotepec, Puebla, México. La hipótesis de trabajo plantea que las cinco especies seleccionadas tienen un valor de importancia cultural mayor para la comunidad Totonaca (Santa María) que para la comunidad mestiza (Cabecera Municipal de Tlacuilotepec). Con base en nueve variables relacionadas con el uso, se desarrolló el índice MERTL para cuantificar la importancia cultural de cada insecto. Se aplicaron técnicas de análisis multivariado (UPGMA y PCA) para analizar la variación en el conocimiento medido a través de este índice. Los resultados muestran que ambas comunidades comparten el conocimiento pero no así el uso de los recursos estudiados. Se rechazó la hipótesis propuesta debido a que en la comunidad mestiza se obtuvieron los valores más altos del índice MERTL, en contraste con la población indígena. Es necesario conservar el conocimiento tradicional e incentivar el uso de este tipo de organismos tanto en comunidades rurales como urbanas; para ello es necesario desarrollar investigaciones mas amplias al respecto.

Polarization-based probabilistic discriminative model for quantitative characterization of cancer cells
Authors: Wan Jiachen , Dong Yang , Xue Jing-Hao , Lin Liyan , Du Shan , Dong Jia , Yao Yue , Li Chao , Ma Hui
Published: April 2022

We propose a polarization-based probabilistic discriminative model for
deriving a set of new sigmoid-transformed polarimetry feature
parameters, which not only enables accurate and quantitative
characterization of cancer cells at pixel level, but also accomplish
the task with a simple and stable model. By taking advantages of
polarization imaging techniques, these parameters enable a
low-magnification and wide-field imaging system to separate the types
of cells into more specific categories that previously were
distinctive under high magnification. Instead of blindly choosing the
model, the L0 regularization method is used to obtain the simplified
and stable polarimetry feature parameter. We demonstrate the model
viability by using the pathological tissues of breast cancer and liver
cancer, in each of which there are two derived parameters that can
characterize the cells and cancer cells respectively with satisfactory
accuracy and sensitivity. The stability of the final model opens the
possibility for physical interpretation and analysis. This technique
may bypass the typically labor-intensive and subjective tumor
evaluating system, and could be used as a blueprint for an objective
and automated procedure for cancer cell screening.
TRA: an efficient dynamic resource assignment algorithm for MCF-based SS-FONs
Authors: Petale Shrinivas , Zhao Juzi , Subramaniam Suresh
Published: April 2022

Service provisioning can be enhanced with spectrally spatially flexible
optical networks (SS-FONs) with multicore fibers; however, intercore
crosstalk (XT) is a dominant impairment that complicates the problem
of maintaining the quality of transmission (QoT) and resource
allocation. The selection of modulation formats (MFs), due to their
unique XT sensitivities, further increases the complexity. The
routing, modulation, core, and spectrum assignment (RMCSA) problem
must select the resources carefully to exploit the available capacity
while meeting the desired QoT. In this paper, we propose an RMCSA
algorithm called the tridental resource assignment (TRA) algorithm for
transparent SS-FONs, and its variant, translucency-aware TRA (TaTRA),
for translucent SS-FONs. TRA balances three different factors that
affect network performance under dynamic resource allocation. We
consider translucent networks with flexible regeneration and with and
without modulation and spectrum conversion. Our resource assignment
approach includes both an offline network planning component to
calculate path priorities and an online/dynamic provisioning component
to allocate resources. Extensive simulation experiments performed in
realistic network scenarios indicate that TRA and TaTRA significantly
reduce the bandwidth blocking probability by several orders of
magnitude in some cases.
Nonlinear rotation of spin-orbit coupled states in hollow ring-core fibers
Authors: Dacha Sai Kanth , Zhu Wenqi , Agrawal Amit , Ritter Kenneth J. , Murphy Thomas E.
Published: April 2022

We experimentally demonstrate that when two spin-orbit coupled orbital angular momentum (OAM) modes of opposite topological charge co-propagate in the Kerr nonlinear regime in a hollow ring-core optical fiber, the vectorial mode superposition exhibits a unique power-dependent rotation effect. This effect is analogous to nonlinear polarization rotation in single-mode fibers, however, the added spatial dimension produces a visually observable rotation of the spatial pattern emerging from the fiber when imaged through a linear polarizer. A dielectric metasurface q-plate was designed and fabricated to excite the desired mode combination in a hollow ring-core fiber that supports stable propagation of OAM modes. The observed spatial patterns show strong agreement with numerical simulations of the vector coupled nonlinear Schrödinger equations. These results constitute the first measurements of what can be described as the spin-orbit coupled generalization of the nonlinear polarization rotation effect.
Generation of complicated millimeter-wave beams based on a wideband high-transmission polarization-independent complex-amplitude metasurface
Authors: Qi Jurui , Liu Ji , Yao Jin , Hu Wenman , Zhang Dajun , Wang Xiong
Published: April 2022

Complex amplitude modulation metasurfaces (CAMM) that can independently control both amplitude and phase have fostered a broad research interest worldwide due to its more robust wave manipulation capability than metasurfaces that can only adjust phase. Although many CAMM structures have been reported, they still suffer from limitations such as low transmittance, complicated structure, polarization dependence, high cost, and difficulty in fabrication. This work proposes a high-transmission polarization-independent CAMM operating in an ultra-wide millimeter-wave frequency range from 30 to 50 GHz realized by cost-effective and easily implementable manners. Three CAMMs are designed to generate complicated millimeter-wave beams like holographic imaging beam, Airy beam, and vortex knot beam. The presented simulation and experimental results clearly demonstrate the effectiveness of the CAMMs. This work presents a new paradigm for CAMM that can be readily extended to other frequency bands. It may also advance further applications of millimeter-wave beams in communication, imaging and detection.
Magneto-optical rotation: accurate approximated analytical solutions for single-probe atomic magnetometers
Authors: Deng Lu , Deng Claire
Published: April 2022

We report an approximated analytical solution for a single-probe four-state atomic magnetometer where no analytical solution exists. This approximated analytical solution demonstrates excellent accuracy in broad probe power and detuning ranges when compared with the numerical solution obtained using a 4th order Runge-Kutta differential equation solver on MATLAB. The theoretical framework and results also encompass widely applied single-probe three-state atomic magnetometers for which no analytical solution, even approximated, is available to date in small detuning regions.
Plasmonic properties of gold nanostructures on Hf-doped ZnO film and its application for refractive index sensing with a high figure of merit
Authors: Venugopalan Priyamvada , kumar Sunil
Published: April 2022

This paper reports a systematic study of the plasmonic properties of periodic arrays of gold nanoparticles in contact with a novel transparent conducting oxide (TCO) material - Hafnium-doped zinc oxide (HZO). Resonant coupling of the grating diffraction orders with the propagating surface plasmons along the waveguide film, which can generate large field enhancements, are investigated by FDTD simulations. By tuning the ratio of Hf dopants to ZnO film, the plasmon resonances can be tuned and narrower resonance with FWHM of 2-5 nm are observed. Such plasmonic substrates are shown in this study to have high figure of merit in refractive index sensing applications.
Short duration overnight cattle kraaling in natural rangelands: Does time after kraal use affect their utilization by wildlife and above ground grass parameters?
Authors: Huruba Rangarirai , Nemera Servious , Ngute Faith , Sahomba Meshack , Mundy Peter J. , Sebata Allan , MacFadyen Duncan N.
Published: April 2022

In east and southern Africa some private ranch owners are corralling (hereafter kraaling) cattle overnight for short periods (for example, seven days) in natural rangelands to create nutrient enriched hotspots which are attractive to large herbivores. However, the effect of season and time after kraal use (alt. age of nutrient enriched hotspots) on large herbivore use of these sites has not been examined. We collated the number of large herbivore sightings per day from camera traps during wet, early and late dry season in nutrient enriched hotspots of varying ages (1, 2, 3 and 4 years) and surrounding vegetation. In addition, above ground grass biomass and height in nutrient enriched hotspots was compared to that of the surrounding vegetation. Furthermore, we tested if repeated grazing in nutrient enriched hotspots stimulated grass compensatory growth. Large herbivore use of nutrient enriched hotspots was similar during wet, early and late dry season. Time after kraal use had a significant effect on mixed feeders (impala and African savanna elephant) utilization of nutrient enriched hotspots but not grazers (zebra and warthog) and browsers (giraffe and greater kudu). Both impala and African savanna elephants mostly used nutrient enriched hotspots one year after kraal use. Aboveground grass biomass and height were higher in surrounding vegetation than in nutrient enriched hotspots. Repeated clipping (proxy for grazing) resulted in compensatory aboveground grass biomass in nutrient enriched hotspots, which declined with time after kraal use. We concluded that nutrient enriched hotspots created through short duration overnight kraaling were important foraging sites for large herbivores.

Published: April 2022

Background

COVID-19 household transmissibility remains unclear in Pakistan. To understand the dynamics of Severe Acute Respiratory Syndrome Coronavirus disease epidemiology, this study estimated Secondary Attack Rate (SAR) among household and close contacts of index cases in Pakistan using a statistical transmission model.

Methodology

A retrospective cohort study was conducted using an inclusive contact tracing dataset from the provinces of Punjab and Khyber-Pakhtunkhwa to estimate SAR. We considered the probability of an infected person transmitting the infection to close contacts regardless of residential addresses. This means that close contacts were identified irrespective of their relationship with the index case. We assessed demographic determinants of COVID-19 infectivity and transmissibility. For this purpose based on evolving evidence, and as CDC recommends fully vaccinated people get tested 5–7 days after close contact with a person with suspected or confirmed COVID-19. Therefore we followed the same procedure in the close contacts for secondary infection.

Findings

During the study period from 15th May 2020 to 15th Jan 2021, a total of 339 (33.9%) index cases were studied from 1000 cases initially notified. Among close contact groups (n = 739), households were identified with an assumed mean incubation period of 8.2+4.3 days and a maximum incubation period of 15 days. SAR estimated here is among the household contacts. 117 secondary cases from 739 household contacts, with SAR 11.1% (95% CI 9.0–13.6). All together (240) SAR achieved was 32.48% (95% CI; 29.12–37.87) for symptomatic and confirmed cases. The potential risk factors for SAR identified here included; old age group (>45 years of age), male (gender), household members >5, and residency in urban areas and for index cases high age group. Overall local reproductive number (R) based on the observed household contact frequencies for index/primary cases was 0.9 (95% CI 0.47–1.21) in Khyber Pakhtunkhwa and 1.3 (95% CI 0.73–1.56) in Punjab.

Conclusions

SAR estimated here was high especially in the second phase of the COVID-19 pandemic in Pakistan. The results highlight the need to adopt rigorous preventive measures to cut the chain of viral transmission and prevent another wave of COVID-19.
Poisoning among children in Malaysia: A 10-years retrospective study
Authors: Alwan Iqdam Abdulmaged , Brhaish Ali Saeed , Awadh Ammar Ihsan , Misnan Asdariah , Rahim Nur Arzuar Abdul , Tangiisuran Balamurugan , Abdul Majid Mohamed Isa
Published: April 2022

Background

Poisoning commonly occurs among children due to their curiosity, where they tend to explore and investigate their surroundings. They frequently put what they find into their mouths as they do not understand the danger and probably cannot read the warning label. As this issue has not been extensively studied in Malaysia; hence, a retrospective analysis of records was carried out to determine the profile of phone call enquiries regarding poisoning among children at the National Poison Centre (NPC).

Methodology

The records of all cases of poisoning among children below the age of 18 years were retrospectively reviewed over a period of 10 years from 2006 to 2015. The data on the cases were analysed according to age group and gender, the circumstances and the toxic agent implicated in the poisoning.

Results

During the 10-year study period, 13,583 calls that met the criteria for this study were referred to the NPC. Of these calls, 62.2% involved children between the age of 0 to 5 years, 9% were children aged between 6 to 12 years, and 28.8% were children between 13 to 18 years. Unintentional poisoning accounted for 96.7% of the incidents involving children between the age of 0 to 5 years, although among the children who were between the age of 13 to 18 years, 76% of the cases were intentional. In all the cases involving children, pharmaceutical agents were the most frequent source of the poisoning. More than 95% of the cases were exposed to poisoning through the oral route.

Conclusion

Poisoning in children between the age of 0 to 5 years was mainly unintentional, while poisoning in children between the age of 13 to 18 years was mainly intentional, where pharmaceutical and household agents were responsible for more than two-thirds of the poisoning cases. Most of these incidents could have been prevented if protective measures, such as child-resistant enclosures, had been implemented and if the parents and guardians had been educated about preventive measures, such as keeping poisoning agents out of the reach of children.
When eleven does not equal 11: Investigating exactness at a number’s upper bound
Authors: Noveck Ira , Fogel Martial , Van Voorhees Kira , Turco Giuseppina
Published: April 2022

The approximate number system (a) views number as an imprecise signal that (b) functions equivalently regardless of a number’s initial presentation. These features do not readily account for exact readings when a task calls for them. While profiting from insights in areas neighboring the number cognition literature, we propose that linguistic-pragmatic and cultural pressures operate on a number’s upper bound in order to provide exact readings. With respect to (a), Experimental Pragmatic findings indicate that numbers appear to be semantically lower-bounded (Eleven candidates are coming means at least eleven) but fluid at its upper-bound; exactly readings emerge as a consequence of an additional pragmatic process that solidifies the upper bound. With respect to (b), studies from cognitive anthropology underline how symbolic representations of number are distinct from written codes. Here, we investigate a novel hypothesis proposing that symbolic expressions of number (such as “11”) explicitly provide exactly readings unlike verbal (oral and written) ones, which engender at least readings. We then employ a Numerical Magnitude Task (NMT), in which French-speaking participants determine whether a presented number is lesser or greater than a benchmark (12) in one of three presentation conditions: i) Symbolic/Hindu-Arabic (e.g. “11” via screen), ii) Oral (e.g. “/ˈon.zə/” via headphones), or; iii) spelled-out-in-Letters (e.g. “onze” via screen). Participants also carry out a Number Identification Task (NIT) so that each participant’s recognition speed per number can be removed from their NMT times. We report that decision reaction times to “onze” take longer to process (and prompt more errors) than “treize” whereas “11” and “13” are comparable. One prediction was not supported: Decision times to the critical oral forms (“/ˈon.zə/” and “[tʁ̥ɛːzə̆]”) were comparable, making these outcomes resonate with those in the Symbolic condition.
Possible misdiagnosis, inappropriate empiric treatment, and opportunities for increased diagnostic testing for patients with vulvovaginal candidiasis—United States, 2018
Authors: Benedict Kaitlin , Lyman Meghan , Jackson Brendan R.
Published: April 2022

Vulvovaginal candidiasis (VVC) is a common cause of vaginitis, but the national burden is unknown, and clinical diagnosis without diagnostic testing is often inaccurate. We aimed to calculate rates and evaluate diagnosis and treatment practices of VVC and recurrent vulvovaginal candidiasis (RVVC) in the United States. We used the 2018 IBM® MarketScan® Research Databases, which include health insurance claims data on outpatient visits and prescriptions for >28 million people. We used diagnosis and procedure codes to examine underlying conditions, vaginitis-related symptoms and conditions, diagnostic testing, and antibacterial and antifungal treatment among female patients with VVC. Among 12.3 million female patients in MarketScan, 149,934 (1.2%) had a diagnosis code for VVC; of those, 3.4% had RVVC. The VVC rate was highest in the South census region (14.3 per 1,000 female patients) and lowest in the West (9.9 per 1000). Over 60% of patients with VVC did not have codes for any diagnostic testing, and microscopy was the most common test type performed in 29.5%. Higher rates of diagnostic testing occurred among patients who visited an OB/GYN (53.4%) compared with a family practice or internal medicine provider (24.2%) or other healthcare provider types (31.9%); diagnostic testing rates were lowest in the South (34.0%) and highest in the Midwest (41.0%). Treatments on or in the 7 days after diagnosis included systemic fluconazole (70.0%), topical antifungal medications (19.4%), and systemic antibacterial medications (17.2%). The low frequencies of diagnostic testing for VVC and high rates of antifungal and antibacterial use suggest substantial empiric treatment, including likely overprescribing of antifungal medications and potentially unnecessary antibacterial medications. These findings support a need for improved clinical care for VVC to improve both patient outcomes and antimicrobial stewardship, particularly in the South and among non-OB/GYN providers.

Attachment to the intestinal epithelium is critical to the lifestyle of the ubiquitous parasite Giardia lamblia. The ventrolateral flange is a sheet-like membrane protrusion at the interface between parasites and attached surfaces. This structure has been implicated in attachment, but its role has been poorly defined. Here, we identified a novel actin associated protein with putative WH2-like actin binding domains we named Flangin. Flangin complexes with Giardia actin (GlActin) and is enriched in the ventrolateral flange making it a valuable marker for studying the flanges’ role in Giardia biology. Live imaging revealed that the flange grows to around 1 μm in width after cytokinesis, then remains uniform in size during interphase, grows in mitosis, and is resorbed during cytokinesis. A flangin truncation mutant stabilizes the flange and blocks cytokinesis, indicating that flange disassembly is necessary for rapid myosin-independent cytokinesis in Giardia. Rho family GTPases are important regulators of membrane protrusions and GlRac, the sole Rho family GTPase in Giardia, was localized to the flange. Knockdown of Flangin, GlActin, and GlRac result in flange formation defects. This indicates a conserved role for GlRac and GlActin in forming membrane protrusions, despite the absence of canonical actin binding proteins that link Rho GTPase signaling to lamellipodia formation. Flangin-depleted parasites had reduced surface contact and when challenged with fluid shear force in flow chambers they had a reduced ability to remain attached, confirming a role for the flange in attachment. This secondary attachment mechanism complements the microtubule based adhesive ventral disc, a feature that may be particularly important during mitosis when the parental ventral disc disassembles in preparation for cytokinesis. This work supports the emerging view that Giardia’s unconventional actin cytoskeleton has an important role in supporting parasite attachment.

First study on molecular detection of three major canine tick-borne pathogens in subclinically infected dogs in Chiang Mai, Thailand
Authors: Tazawa Keiichiro , Poolsawat Napassorn , Gibson Andrew D. , Gamble Luke , King Alasdair , Anuracpreeda Panat
Published: April 2022

Background and Aim: Canine tick-borne pathogens (CTBPs) are an important cause of morbidity in dogs in Thailand. This study aimed to evaluate the occurrence of three CTBPs in clinically normal, owned dogs to understand the risk for the general canine population. We also examined sex, age, tick infestation, and packed cell volume (PCV) of the animals in association with active infection of the CTBPs. Materials and Methods: A total of 139 dogs were included in the study. Blood samples were collected for thin blood smear, PCV and nested polymerase chain reaction (PCR) assay. Statistical analyses were performed to examine the association between individual factors and CTBP infection status determined by PCR. In addition, sensitivity, specificity, and Cohen's kappa were calculated to assess the utility of routine blood smear. Results: The PCR results showed that 31 dogs (22.3%) were infected with at least one of the three pathogens. The occurrence rate for Ehrlichia canis, Anaplasma platys, and Hepatozoon canis was 2.2% (3/139), 18.7% (24/139), and 2.8% (4/139), respectively. There were two cases of coinfection with A. platys and E. canis. The univariate analyses did not yield any associations between recorded variables and the active infection. Microscopic examination showed good sensitivity and agreement only for H. canis (Sn: 75%, 95% confidence interval: 24.9-98.7, κ=0.85). Conclusion: Our findings confirmed the endemicity of the CTBPs in owned canine population in the study site. In-depth epidemiological investigation would be warranted to elucidate environmental risk factors for CTBP infection.

ANÁLISE CONFIGURACIONAL SOBRE OS USOS DAS TICS NA EDUCAÇÃO FÍSICA ESCOLAR DURANTE A PANDEMIA
Authors: Giordani Vasques Daniel , Py Mariante Neto Flávio
Published: April 2022

Essa pesquisa teve como objetivo analisar os usos das tecnologias da informação e da comunicação (TIC) para o ensino da Educação Física escolar em uma escola pública de ensino básico durante o ensino remoto. Para tal, os dados foram produzidos a partir de uma pesquisa-ação. Três elementos empírico-analíticos compuseram a configuração: as normas da escola, as condições de acesso e as intencionalidades pedagógicas. As transformações no ensino passaram da manutenção do vínculo dos estudantes com a escola ao aumento dos instrumentos de controle e de autocontrole e o incremento nas possibilidades de interação professor-estudante. A incorporação de um habitus educacional remoto se relaciona com a transitoriedade da configuração e das tensões. As TIC são um elemento civilizador de um processo de educação que perpassa a construção das emoções. Ao mesmo tempo que essas se transformam, potencializam-se as diferenças sociais; à educação cabe agir como fator de resistência a esses processos.

Este ensaio analítico objetiva refletir acerca da implementação da reforma do Ensino Médio na Rede Estadual de Ensino do Rio Grande do Sul (REERS), considerando a intercorrência do ensino remoto emergencial devido à pandemia da COVID-19. Para isso, são apresentados conhecimentos produzidos a partir da experiência docente em Educação Física no ensino remoto, e, de um estudo de caso etnográfico realizado em escolas-piloto da reforma do Ensino Médio. Diante das dificuldades enfrentadas, as escolas públicas estaduais não têm condições de ofertar a parte diversificada do novo modelo curricular, o que poderá ser suprido por empresas do mercado educacional por meio de financiamentos garantidos por recursos públicos. Portanto, as mudanças propostas pela reforma do Ensino Médio atendem a interesses privatistas, o que também se verifica nas medidas tomadas para a oferta do Ensino Remoto Emergencial na REERS.

Published: April 2022

O artigo debate a formação continuada de professores de Educação Física. O objetivo é analisar os efeitos da realização de cursos de extensão para professores de Educação Física em tempos de distanciamento social, ocasionado pela pandemia de Covid-19. Trata-se de uma pesquisa qualitativa que se debruçou a analisar materiais oriundos de dois cursos de extensão, promovidos pela Universidade Federal do Rio Grande do Sul, nos anos de 2020 e 2021. O curso foi realizado pelo Youtube e pela plataforma Moodle. Foram analisados os comentários dos participantes nos chats do canal Youtube e textos produzidos como tarefa final do curso, publicados na forma de e-books. Nota-se que os professores expressam reflexões sobre sua prática na ocasião dos debates e procuram constituir seu fazer pedagógico a partir dos temas debatidos no curso. Destaca-se a importância de ofertar formação docente de qualidade e de aproximar a universidade da escola.

A interdisciplinaridade na prática da Educação Ambiental e no trabalho docente:
Authors: Silva Marcus Furtado da , Silveira Júnior Arialdo Martins da
Published: April 2022

Partindo do pressuposto que a educação ambiental é fundamental para uma sensibilização voltada para a relação da sociedade com o meio, o presente trabalho tem como objetivo verificar a aplicabilidade da interdisciplinaridade da educação ambiental com discentes do 6º ano da Escola Estadual Irmã Santina Rioli na cidade de Macapá, Estado do Amapá, bem como a atuação docente nesta perspectiva. Desta forma, o presente trabalho partiu de uma condensada pesquisa com visitações in locu e aplicação de questionários a estudantes (n=73) e professores (n=6). Observamos que a educação ambiental precisa ser pensada e, constantemente, reinventada na escola campo, visando acompanhar, eminentemente, o processo de evolução dos conceitos acerca desta temática. A interdisciplinaridade, ainda, se apresenta de forma incipiente e fragilizada, seja pela falta de incentivo e recursos na escola, bem como pela frágil formação para a prática docente na perspectiva da Educação Ambiental. A Escola Estadual Irmã Santina Rioli enxerga o trabalho interdisciplinar como sendo indispensável; entretanto, não fomenta e potencializa o seu desenvolvimento, o que impossibilita a troca de experiências e a transversalidade do diálogo das questões ambientais.

Authors: Rondón Yonezka
Published: April 2022

El propósito de este ensayo es analizar la influencia de la Región Histórica margariteña en la conformación de redes comerciales en el Caribe a partir del eje político y económico: La Asunción- Pampatar como resultado de la actividad agropecuaria y del intercambio comercial que mantuvo tanto con Tierra Firme como con las Antillas y Europa. Asimismo, se analiza y el crecimiento de un comercio ilícito que se tejió alrededor de la actividad perlera y el tráfico negrero desde el siglo XVI hasta el XVIII. Se desarrolla con esta investigación el estudio de las interrelaciones de la Isla de Margarita con los espacios vecinos y sus ciudades tal como es el caso del eje La Guaira-Caracas, Guayana, Barcelona, Cumaná, Trinidad-Puerto España, Puerto Rico y Santo Domingo lo cual produjo redes comerciales caribeñas de gran importancia y significación.
Primera aproximación a la conexión teórica entre los conceptos de Patrimonio, Desarrollo Social, Centro Histórico, Teoría de Sistemas y Cartografía Cultural
Authors: Acevedo Navas Christian , Vergara Durán Ricardo Adrián
Published: April 2022

En el presente artículo se aborda la relación teórica entre los conceptos de patrimonio, desarrollo social, centro histórico, teoría de sistemas y cartografía cultural. Primero se relacionan los conceptos de patrimonio y desarrollo social. Posteriormente se relacionan los conceptos de centro histórico y patrimonio. Seguido se hace una revisión de los elementos más destacados de la teoría de sistemas y se relacionan con el concepto de centro histórico. Finalmente se revisa el concepto de cartografía cultural y su relación con el centro histórico. El objetivo es elaborar un primer intento de una línea argumentativa que conecte estos conceptos en el marco de entender por qué el centro histórico se convierte en un subsistema de la ciudad, capaz de representarla, en el sentido de su estudio y análisis sociológico amplio; y susceptible de generar procesos de desarrollo social, en un sentido práctico social.
Peinillas y participación popular: Pelea de machetes en Haiti, Cuba y Colombia
Authors: Desch-Obi T. J.
Published: April 2022

Este artículo explora la historia de esgrima con machetes entre los afro-descendientes en Haití, Cuba y Colombia. El machete, como un ícono sagrado de éxito individual y de guerra en África, se convierte para los esclavizados Africanos en una herramienta usada en la explotación de su trabajo. Ellos retuvieron la maestría en esta arma a través de la extensión del arte de pelea con palos. Esta maestría en las armas blancas ayudó a transformar el machete en un importante instrumento en las batallas nacionales de esas tres naciones. Aún en el comienzo del siglo veinte, el arte de esgrima con machetes fue una práctica social muy expandida entre los Afro-Caucanos, que les permitía demostrar su honor individual, como también hacer importantes contribuciones a las batallas nacionales, como la Colombo-Peruana. Aunque la historia publicada de las batallas nacionales realza la importancia de los líderes políticos y militares, los practicantes de estas formas de esgrima perpetuaron importantes contra- memorias que enfatizan el papel de soldados Afros quienes con su maestría con el machete pavimentaron el camino para la victoria nacional
Sociabilidades modernas: sociedades fraternales secretas en el Caribe costarricense a finales del siglo XIX
Authors: Martínez Esquivel Ricardo
Published: April 2022

Puerto Limón en el caribe costarricense fue transformado en un espacio multicultural y de interacción étnica a finales del siglo XIX debido a su vinculación con el mercado internacional, la construcción del ferrocarril y al desarrollo de la industria bananera. A este puerto llegaron europeos de las más diversas procedencias, estadounidenses, latinoamericanos y afrodescendientes criollos del Caribe, quienes con sus distintos acervos culturales definieron costumbres, hábitos de consumo y formas de sociabilidad. La sociedad limonense para estos años adquirió una dinámica más liberal, progresista, modernista y cosmopolita, que muchas otras partes de Costa Rica. La situación anterior facilitó el establecimiento de sociedades fraternales secretas como la masonería y los Knights of Pythias, microespacios de sociabilidad donde cohesionaron personas de distintas culturas y procedencias. El estudio de este tipo de agrupaciones es una tarea todavía pendiente en el Caribe, por lo que esta investigación es un aporte.
Centros Históricos: El Patrimonio como herramienta del Desarrollo Socia
Authors: Vergara Durán Ricardo Adrián
Published: April 2022

Entender el patrimonio como una herramienta del desarrollo social es fundamental y más aun imprescindible para evitar que el patrimonio sea visto solo como un acto de memoria. Igualmente importante es entender el desarrollo social desde una visión que integre los elementos identitarios y culturales de un grupo social evitando caer erradamente solo en aspectos económicos. La valoración patrimonial no es el fin en sí mismo, sino que a través de ella una sociedad puede lograr reconocer su capacidad creativa y transformadora para promover su propio desarrollo. Es importante en este contexto reconocer que el patrimonio se crea cotidianamente en la apropiación y uso de sus espacios, siendo el centro histórico, como espacio público por excelencia uno de los más importantes en las ciudades.
Reseña del libro: Barrio El Prado. Hito histórico y urbano de Barranquilla
Authors: Villalón Jorge
Published: April 2022

El Barrio El Prado surgió en 1920 por la iniciativa de los hermanos Roberto y Karl Parrisch, dos empresarios norteamericanos quienes se establecieron a vivir en Barranquilla en donde participaron en varios proyectos relacionados con el desarrollo de la ciudad. Entre estos diversos proyectos hay que mencionar la gestión y ejecución de un acueducto moderno, la construcción del puerto con sus obras en Bocas de Ceniza, la carretera a Puerto Colombia y a Ciénaga y en la segunda generación el proyecto educativo Fundación de la Universidad del Norte. De alguna manera esta familia ha sido una de las más influyentes en lo que tiene que ver con el desarrollo urbano de Barranquilla y sus descendientes continúan haciendo proyectos e inversiones en esta actividad.
an difíciles tiempos para Cuba. El gobierno del Marqués de Someruelos (1799-1812)
Authors: Martín Jiménez Virginia
Published: April 2022

“Tan difíciles tiempos para Cuba”, fruto de la tesis doctoral del investigador sevillano Sigfrido Vázquez Cienfuegos, es una monografía acerca de Salvador José Muro y Salazar, Marqués de Someruelos, quien fue capitán general y gobernador de La Habana entre 1799 y 1812. Estos años no sólo representaron uno de los gobiernos más duraderos que habían existido en la isla sino que significaron el final del Antiguo Régimen y el comienzo de la contemporaneidad de la historia. Por lo tanto, fueron tiempos convulsos que marcaron el devenir de la colonia española.
Trauma als Wissensarchiv
Authors: Scharf da Silva Inga
Published: April 2022

Bei der brasilianischen Religion Umbanda – die sich im Bundesstaat von Rio de Janeiro am Anfang des 20. Jahrhunderts auf der Grundlage von afrikanischen, indigenen und europäischen Religionen bildete – steht die Kommunikation mit Geistwesen im Zentrum, die an die brasilianische Geschichte erinnern. Seit den 1940er Jahren ist sie weltweit verbreitet und ab ca. 2010 auch im Zuge der transatlantischen sakralen Globalisierung im deutschsprachigen Europa angesiedelt. Dennoch ist ihre Ausbreitung bislang kaum erforscht. Inga Scharf da Silva schließt hier eine Forschungslücke, indem sie sich auf der Grundlage einer über fünfjährigen ethnologischen Feldforschung mit der spirituellen Gemeinschaft des Ilê Axé Oxum Abalô (auch Terra Sagrada genannt) befasst, die ihr Mutterhaus in den Schweizer Bergen im Kanton Appenzell verortet und mit sieben Ablegern in Graz und Wien, Zürich und Bern, Berlin und Cumuruxatiba in Brasilien ein überregionales Netzwerk bildet. Jedes Kapitel der Studie wird durch das Porträt einer Gottheit (Orixá) sowie Narrative aus den mythischen Überlieferungen gerahmt und zu Textpassagen von Oswald de Andrades ›Manifesto Antropófago‹ und Umberto Ecos ›Foucaultschem Pendel‹ in Bezug gesetzt. Dabei verdeutlicht die Autorin, wie die religiöse Praxis der Trance als Einverleibung von Bewusstseinsstrukturen zur Reflexion der Wissensproduktion ihrer Religion und darüber hinaus zu einer Dekolonialisierung des Denkens in Europa beitragen kann.
