The Brown Adventure Romance: Chander Pahar and the Management of Racial Capital
Authors: Sengupta Oishani
Published: March 2024

Abstract: Can the archetypal imperial adventurer—the hero of empire's interlinked fictions of discovery and conquest—be brown? This question finds expression in a genre of Bengali literature yet to receive significant scholarly attention. Rather than viewing these novels as a case of Bengal "writing back" to the British genre of the imperial romance, I read them as enquiries into the turbulent shifts of race, migration, and fractured self-fashioning in the age of decolonization. Through a closer look at Bibhutibhushan Bandyopadhyay's Chander Pahar or The Mountain of the Moon (1937), the essay demonstrates how traces of indentureship and coolie labor as abject and elided forms of brown/ness fracture both the category of the brown expeditioner and its effect on the stereotypes of the dark continent.
Feeling Brown, Thinking Black: Translating the Black Panther from Lowndes to Bombay
Authors: Shailendra Soumya Rachel
Published: March 2024

Abstract: The archive of exchanges between Dalit and Black intellectuals exhibits the significance of imagining and translating minoritarian relations in the late twentieth century. The formation of the Dalit Panthers—an anticaste organization that declared its affiliation to the Black Panther Party in 1973—presents one such translational moment, revealing the affective power of brown/ness in consolidating minoritarian worlds that are concomitantly conceived in their opposition to coloniality, caste, and white supremacy. I trace the evolution of the Panthers' relationship through the journey of its iconography, from its initial sketching in Lowndes to its circulation in Marathi little magazines in the 1970s and its reappearance in Rahee Punyashloka's print series The Panthers Is an Elusive Beast (2021).

Authors: Su Cong , Janzen Eli , He Mingze , Li Chi , Zettl Alex , Caldwell Joshua D. , Edgar James H. , Aharonovich Igor
Published: March 2024

Hexagonal boron nitride (hBN), also known as white graphite, is a
transparent layered crystal with a wide bandgap. Its crystal structure
resembles graphite, featuring layers composed of honeycomb lattices
held together through van der Waals forces. The layered crystal
structure of hBN facilitates exfoliation into thinner flakes and makes
it highly anisotropic in in-plane and out-of-plane directions. Unlike
graphite, hBN is both insulating and transparent, making it an ideal
material for isolating devices from the environment and acting as a
waveguide. As a result, hBN has found extensive applications in
optical devices, electronic devices, and quantum photonic devices.
This comprehensive tutorial aims to provide readers with a thorough
understanding of hBN, covering its synthesis, lattice and
spectroscopic characterization, and various applications in
optoelectronic and quantum photonic devices. This tutorial is designed
for both readers without prior experience in hBN and those with
expertise in specific fields seeking to understand its relevance and
connections to others.

Published: March 2024

An ML-supported diagnostics concept is introduced and demonstrated to detect and classify events on OTDR traces for application on a PON optical distribution network. We can also associate events with ODN branches by using deployment data of the PON. We analyze an ensemble classifier and neural networks, the usage of synthetic OTDR-like traces, and measured data for training. In our proof-of-concept, we show a precision of 98% and recall of 95% using an ensemble classifier on measured OTDR traces and a successful mapping to ODN branches or groups of branches. For emulated data, we achieve an average precision of 70% and an average recall of 91%.
Millimeter-wave over fiber integrated sensing and communication system using self-coherent OFDM

Published: March 2024

Orthogonal frequency-division multiplexing (OFDM) waveform is highly preferred as a dual-function candidate for integrated sensing and communication (ISAC) systems. However, the sensitivity to both carrier frequency offset (CFO) and phase noise greatly impedes its applications in millimeter-wave ISAC systems. Here, we propose and experimentally demonstrate a photonic millimeter-wave ISAC system employing the virtual-carrier-aided self-coherent OFDM technique, wherein a digitally-generated local oscillator is transmitted along with the OFDM signal. Then, a compact CFO-immune and phase noise-immune envelope detection method is implemented for down-converting millimeter-wave communication and radar echo signals. In experiments, a V-band ISAC system is successfully implemented with a simplified remote radio unit, using the remote photonic millimeter-wave heterodyning up-conversion for downlink and the envelope detection-assisted down-conversion for uplink (or radar echoes). In the converged transmission link with a 5-km fiber link and 2-m space link, the Kramers–Kronig (KK) receiver supports a communication data rate up to 16-Gbit/s by mitigating signal-signal beat interference (SSBI). More significantly, the SSBI leads to negligible effects on the sensing performance when classic matched filtering is adopted for target identification. Consequently, a 4.8-cm range resolution and a 4-mm range accuracy are obtained for the radar sensing function.
Research on the removal characteristics of surface error with different spatial frequency based on shear thickening polishing method

Published: March 2024

X-ray mirrors, which are essential for constructing synchrotron radiation light sources, are highly required for full-range spatial wavelength errors. This paper investigated power-law non-Newtonian fluids and pointed out that both three-body removal and shear removal existed in the shear thickening polishing process. Subsequently, this paper calculates the shear force of the power-law non-Newtonian fluid polishing fluid in polishing the surface with different frequency errors. It establishes an MRR model of shear thickening polishing in the frequency domain by combining it with the Archard equation. Then, this model is also applied to optimize the polishing fluid formulation and processing parameters. Finally, the removal effect of the optimized polishing fluid on the mid-frequency ripple error is experimentally verified. On Ф50 mm monocrystalline silicon, the removal of mid-frequency ripple error with a spatial wavelength of 1 mm was achieved by shear thickening polishing technique while converging the surface roughness to 0.14 nm. Finally, the experimental results were applied to monocrystalline silicon with a length of 500 mm. This work provides a new research idea for the existing shear thickening polishing process. It provides theoretical and technical support for removing the mid- and high-frequency errors in high-precision X-ray mirrors.
Hybrid transmission of PS-GS4QAM and QPSK data in the form of a PS-16QAM mm-wave signal enabled by optical asymmetrical dual-SSB modulation
Authors: Yan Hengxin , Xie Tangyao , Li Xinying , Pan Xiaolong , Bi Jiahao , Fang Liye , Lin Qiuying , Xin Xiangjun
Published: March 2024

The independent optical dual-single-sideband (dual-SSB) signal generation and detection can be achieved by an optical in-phase/quadrature (I/Q) modulator and one single photodiode (PD). The dual-SSB signal is able to carry two different information. After PD detection, the optical dual-SSB signal can be converted into an electrical millimeter-wave (mm-wave) signal. Therefore, the optical dual-SSB signal generation and detection technique can be employed in the radio-over-fiber (RoF) system to achieve higher system spectral efficiency and reduce system architecture complexity. However, the I/Q modulator's nonideal property results in the amplitude imbalance of the optical dual-SSB signal, and then the crosstalk can occur. Moreover, after PD detection, the generated mm-wave signal based on the optical dual-SSB modulation has a relatively low signal-to-noise ratio (SNR), which restricts the system performance. In this paper, we propose an optical asymmetrical dual-SSB signal generation and detection scheme based on the probabilistic shaping (PS) technology, to decrease the influence of the optical dual-SSB signal’s amplitude imbalance and to enhance the system performance in the scenario of the limited SNR. The dual-SSB in our scheme is composed of the left sideband (LSB) in probabilistic-shaping geometric-shaping 4-ary quadrature amplitude modulation (PS-GS4QAM) format and the right sideband (RSB) in quadrature phase-shift keying (QPSK) format. The transmitter digital signal processing (DSP) generates a dual-SSB signal to drive the optical I/Q modulator. The I/Q modulator implements an electrical-to-optical conversion and generates an optical dual-SSB signal. After PD detection, the optical dual-SSB signal is converted into a PS-16QAM mm-wave signal. In our simulation, compared with the normal 16QAM scenario, the PS-16QAM scenario exhibits a ∼1.2 dB receiver sensitivity improvement at the hard-decision forward error correction (HD-FEC) threshold of 3.8×10−3. Therefore, in our experiment, based on the PS technology, we design a dual-SSB signal including a 5 Gbaud LSB-PS-GS4QAM at −15 GHz and a 5 Gbaud RSB-QPSK at 20 GHz. After 5 km standard single-mode fiber (SSMF) transmission and PD detection, the dual-SSB signal is converted into a 5 Gbaud PS-16QAM mm-wave signal at 35 GHz. Then, the generated PS-16QAM signal is sent into a 1.2 m single-input-single-output (SISO) wireless link. In the DSP at the receiver end, the dual-SSB signal can be recovered from the mm-wave signal, and the PS-GS4QAM and QPSK data carried by the dual-SSB signal can be separated. The bit error rates (BERs) of the LSB-PS-GS4QAM and the RSB-QPSK in our experiment can be below the HD-FEC threshold of 3.8×10−3. The results demonstrate that our scheme can tolerate the I/Q modulator’s nonideal property and performs well in the scenario of a relatively low SNR.

Visible light communication (VLC) based on laser diodes demonstrates great potential for high data rate maritime, terrestrial, and aerial wireless data links. Here, we design and fabricate high-speed blue laser diodes (LDs) grown on c-plane gallium nitride (GaN) substrate. This was achieved through active region design and miniaturization toward a narrow ridge waveguide, short cavity length, and single longitudinal mode Fabry–Perot laser diode. The fabricated mini-LD has a low threshold current of 31 mA and slope efficiency of 1.02 W/A. A record modulation bandwidth of 5.9 GHz (−3  dB) was measured from the mini-LD. Using the developed mini-LD as a transmitter, the VLC link exhibits a high data transmission rate of 20.06 Gbps adopting the bit and power loading discrete multitone (DMT) modulation technique. The corresponding bit error rate is 0.003, satisfying the forward error correction standard. The demonstrated GaN-based mini-LD has significantly enhanced data transmission rates, paving the path for energy-efficient VLC systems and integrated photonics in the visible regime.
GALDAR: A genetically encoded galactose sensor for visualizing sugar metabolism in vivo
Authors: Sakizli Uğurcan , Takano Tomomi , Yoo Sa Kan
Published: March 2024

Sugar metabolism plays a pivotal role in sustaining life. Its dynamics within organisms is less understood compared to its intracellular metabolism. Galactose, a hexose stereoisomer of glucose, is a monosaccharide transported via the same transporters with glucose. Galactose feeds into glycolysis and regulates protein glycosylation. Defects in galactose metabolism are lethal for animals. Here, by transgenically implementing the yeast galactose sensing system intoDrosophila, we developed a genetically encoded sensor, GALDAR, which detects galactosein vivo. Using this heterologous system, we revealed dynamics of galactose metabolism in various tissues. Notably, we discovered that intestinal stem cells do not uptake detectable levels of galactose or glucose. GALDAR elucidates the role for galactokinase in metabolism of galactose and a transition of galactose metabolism during the larval period. This work provides a new system that enables analyses ofin vivosugar metabolism.
Color Quest: An interactive tool for exploring color palettes and enhancing accessibility in data visualization
Authors: Nelli Luca
Published: March 2024

Data visualization plays a vital role in modern scientific communication across diverse domains, shaping the understanding of complex information through color choices. However, the significance of color palette selection goes beyond aesthetics and scientific communication, encompassing accessibility for all, especially individuals with color vision deficiencies. To address this challenge, we introduce "Color Quest," an intuitive Shiny app that empowers users to explore color palettes for data visualization while considering inclusivity. The app allows users to visualize palettes across various types of plots and maps envisioning how they appear to individuals with color blindness. In addition, it enables users to visualize palettes on their own custom-uploaded images. This short communication presents the app’s design, interactive interface, and transformative potential in enhancing data visualization practices. Developed using open-source standards, Color Quest aligns with accessibility discussions, offering a practical tool and platform for raising awareness about inclusive design. Its open-source nature fosters transparency, community collaboration, and long-term sustainability. Color Quest’s practicality renders it indispensable for scientific domains, simplifying palette selection and promoting accessibility. Its impact extends beyond academia to diverse communication settings, harmonizing information dissemination, aesthetics and accessibility for more impactful scientific communication.

Published: March 2024

Introduction

Complex challenges amongst ageing cohorts of adolescents and adults living with perinatally acquired HIV (PaHIV) may impact on hospitalisation. We report hospitalisation rates and explored predictive factors for hospitalisation in adolescents and adults (10–35 years) living with PaHIV in England.

Method

Retrospective observational cohort study over a three-year period 2016–2019. Data collected included cause and duration of hospitalisation, HIV viral load and CD4 lymphocyte count. The primary outcome was overnight hospitalisation. Patients exited at study end/ transfer of care (TOC)/ loss to follow up (LTFU) or death. Maternity/hospital admissions at other centres were excluded. Admission rates per 100 person-years (95% CI) were calculated by age group. Negative binomial regression with generalized estimating equations was performed.

Results

255 patients contributed 689 person-years of follow up. 56% were female and 83% were of a Black, Black British, Caribbean or African ethnicity. At baseline, the median age was 19 years (IQR 16–22). 36 individuals experienced a total of 62 admissions which resulted in 558 overnight stays (median stay was 5 nights). One person died (lymphoma), six had TOC and one was LTFU by the end of the three-year study period. Crude incidence of admission for the whole cohort was 9.0 per 100 PY (6.9–11.6). The respective crude incidence rates were 1.5 PY (0.0–8.2) in those aged 10–14 years and 3.5 PY (1.5–7.0) in the 15–19-year-olds. In those aged 20–24 years it was 14.5 PY (10.1–20.2) and in those >25 years the crude incidence rate was 11.7 PY (6.9–18.5). Factors significantly associated with admission were a CD4 lymphocyte count <200 cells/uL, adjusted IRR 4.0 (1.8–8.8) and a history of a CDC-C diagnosis, adjusted IRR 2.9 (1.6–5.3). 89% admissions were HIV-related: 45% new/current CDC-C diagnoses, 76% due to infection.

Conclusions

Hospitalisation rates were four-fold higher in adults (>20 years of age) compared to adolescents (10–19-year-olds). The continuing challenges experienced by PaHIV youth require enhanced multidisciplinary support throughout adulthood.
Do statistical heterogeneity methods impact the results of meta- analyses? A meta epidemiological study
Authors: Mheissen Samer , Khan Haris , Normando David , Vaiid Nikhillesh , Flores-Mir Carlos
Published: March 2024

Background

Orthodontic systematic reviews (SRs) use different methods to pool the individual studies in a meta-analysis when indicated. However, the number of studies included in orthodontic meta-analyses is relatively small. This study aimed to evaluate the direction of estimate changes of orthodontic meta-analyses (MAs) using different between-study variance methods considering the level of heterogeneity when few trials were pooled.

Methods

Search and study selection: Systematic reviews (SRs) published over the last three years, from the 1st of January 2020 to the 31st of December 2022, in six main orthodontic journals with at least one MA pooling five or lesser primary studies were identified. Data collection and analysis: Data were extracted from each eligible MA, which was replicated in a random effect model using DerSimonian and Laird (DL), Paule–Mandel (PM), Restricted maximum-likelihood (REML), Hartung Knapp and Sidik Jonkman (HKSJ) methods. The results were reported using median and interquartile range (IQR) for continuous data and frequencies for categorical data and analyzed using non-parametric tests. The Boruta algorithm was used to assess the significant predictors for the significant change in the confidence interval between the different methods compared to the DL method, which was only feasible using the HKSJ method.

Results

146 MAs were included, most applying the random effect model (n = 111; 76%) and pooling continuous data using mean difference (n = 121; 83%). The median number of studies was three (range 2, 4), and the overall statistical heterogeneity (I2 ranged from 0 to 99% with a median of 68%). Close to 60% of the significant findings became non-significant when HKSJ was applied compared to the DL method and when the heterogeneity was present I2>0%. On the other hand, 30.43% of the non-significant meta-analyses using the DL method became significant when HKSJ was used when the heterogeneity was absent I2 = 0%.

Conclusion

Orthodontic MAs with few studies can produce different results based on the between-study variance method and the statistical heterogeneity level. Compared to DL, HKSJ method is overconservative when I2 is greater than 0% and may result in false positive findings when the heterogeneity is absent.
The impact of multiple abiotic stresses on ns-LTP2.8 gene transcript and ns-LTP2.8 protein accumulation in germinating barley (Hordeum vulgare L.) embryos

Published: March 2024

Abiotic stresses occur more often in combination than alone under regular field conditions limiting in more severe way crop production. Stress recognition in plants primarily occurs in the plasma membrane, modification of which is necessary to maintain homeostasis in response to it. It is known that lipid transport proteins (ns-LTPs) participate in modification of the lipidome of cell membranes. Representative of this group, ns-LTP2.8, may be involved in the reaction to abiotic stress of germinating barley plants by mediating the intracellular transport of hydrophobic particles, such as lipids, helping to maintain homeostasis. The ns-LTP2.8 protein was selected for analysis due to its ability to transport not only linear hydrophobic molecules but also compounds with a more complex spatial structure. Moreover, ns-LTP2.8 has been qualified as a member of pathogenesis-related proteins, which makes it particularly important in relation to its high allergenic potential. This paper demonstrates for the first time the influence of various abiotic stresses acting separately as well as in their combinations on the change in the ns-LTP2.8 transcript, ns-LTP2.8 protein and total soluble protein content in the embryonal axes of germinating spring barley genotypes with different ns-LTP2.8 allelic forms and stress tolerance. Tissue localization of ns-LTP2.8 transcript as well as ns-LTP2.8 protein were also examined. Although the impact of abiotic stresses on the regulation of gene transcription and translation processes remains not fully recognized, in this work we managed to demonstrate different impact on applied stresses on the fundamental cellular processes in very little studied tissue of the embryonal axis of barley.

Paratuberculosis, caused by Mycobacterium avium subsp. paratuberculosis (MAP), is a significant concern in the camel population of Saudi Arabia. This study aimed to provide epidemiological insights into the disease by estimating the true prevalence in camels in the Eastern Province and Riyadh, using a Bayesian estimation framework, and exploring the associated risk factors through a frequentist approach. A total of 1200 camel blood samples were collected and analyzed using an indirect ELISA method. The true herd-level prevalence was estimated at 0.7 (95% probability interval: 0.57 to 0.81), and the mean expected true animal-level prevalence was 0.17 (0.14 to 0.20). Risk factors associated with Map seropositivity were identified, including sex, breed, raising system, and production type. Females, single breed camels, and nomadic raising systems were found to have lower odds of seropositivity, while camels used for racing and show had significantly higher odds. The study’s Bayesian approach, adjusting for the imperfect accuracy of MAP tests, provides a nuanced understanding of the disease’s prevalence in the region. The integration of true prevalence estimates with risk factor analysis offers a comprehensive framework that can guide future policies and strategies in the fight against paratuberculosis in Saudi Arabia. The findings emphasize the importance of targeted control measures, underscoring the urgent need for interventions in Saudi Arabia’s camel population. By understanding the true disease prevalence and its associated risk factors, we can enhance disease management strategies, offering valuable insights for future control and eradication efforts in the region.

Published: March 2024

Purpose

This single-arm prospective cohort study aimed to evaluate the feasibility and utility of in-home body weight support harness system (BWSS) use in children treated for spinal muscular atrophy (SMA).

Methods

Individuals with 2 or 3 copies of SMN2 who received pharmacotherapeutic treatment, had head control, and weight <50lbs were enrolled. Families were provided a BWSS and documented use. Motor outcome assessments were completed at baseline, month 3 and month 6. Families provided feedback in an end of study survey.

Results

All 32 participants (2.9 (SD 1.9) yrs), improved or remained stable on all outcomes. Average reported frequency of use was 4.1(2.3) hrs/week. Controlling for other covariates, frequency of use explained over 70% of the variability in change scores. Family feedback was overwhelmingly positive.

Conclusion

Use of in-home BWSS is a safe, feasible and useful option to increase exercise dosage after treatment in SMA and may help optimize motor abilities.

Warrior-matriarchs’ retrotopia and democracy: Searching for the lost tribe in Alan Duff’s Once Were Warriors
Authors: Rodríguez-Salas Gerardo
Published: March 2024

The novel Once Were Warriors (1990), by Alan Duff, demystified the Māori grand narratives of the past previously romanticized by writings from the Māori Renaissance of the mid-1970s and 1980s. In contrast with the negative portrayal of Māori subjectivities and the political immobility generally perceived by critics, this study aims to reconceptualize male tribal models in Duff’s novel. On the one hand, the rangatira (or male elders) and Māori urban gangs engage in tribal patterns echoing utopias of male domination. Whilst on the other hand, female characters such as Beth Heke, her daughter Grace and the singer Mavis Tangata – as examples of warrior-matriarchs – suggest a recuperation of ancestral warriorhood through open democracy and the hybridity of a revised version of tribalism and the Eucharist.
Sounding out the ‘Hawaiki zone’: What musical instruments reveal about the immediate geographical origins of the peoples who became Māori in Aotearoa
Authors: Cattermole Jennifer
Published: March 2024

A range of linguistic, genetic and archaeological evidence supports the immediate ancestors of Māori having come from central Eastern Polynesia, and this is borne out through a comparative study of central Eastern Polynesian and Māori musical instruments. An examination of Māori musical instruments also shows, however, that a few instrument names, types and usages may be adoptions or adaptations from elsewhere in Oceania – from Hawai‘i, or from Western Polynesia or Eastern Melanesia. While the possibility of convergent evolution cannot be ruled out, these similarities are quite striking and raise some intriguing questions. Are these similarities the result of cultural transmission to central Eastern Polynesia from Hawai‘i and Western Polynesia (and/or Eastern Melanesia) prior to the departure of the ancestors of Māori to Aotearoa? Could they be the result of a limited amount of direct voyaging from Western Polynesia and/or Eastern Melanesia to Aotearoa prior to the Little Ice Age (c.1400), or from later cultural transmission? Are they the vestiges of practices that, in historical times, had been discontinued in central Eastern Polynesia but preserved in marginal Polynesia (as per the ‘stone in the pond’ model of cultural diffusion)? These questions are discussed in this article, which aims to shed further light on the possible origins of Māori musical instruments and, in so doing, the immediate geographical origins of Māori ancestors.
Concepção de conhecimento com base em pressupostos da Teoria Histórico-Cultural
Authors: Lizzi Maria Sandreana Salvador da Silva , Sforni Marta Sueli de Faria
Published: March 2024

Na Teoria Histórico-Cultural e na Teoria do Ensino Desenvolvimental atribui-se grande valor à aprendizagem de conceitos científicos no desenvolvimento dos sujeitos. No entanto, sem a compreensão das razões desse valor, a educação escolar, que se pauta nos pressupostos dessas teorias, pode se limitar ao aspecto mais aparente do ensino desses conceitos e não extrair deles o potencial formativo anunciado. Por essa razão, este artigo expõe o resultado de uma investigação que buscou, na origem histórica dessas teorias, o motivo da ênfase conferida aos conceitos científicos. Identificou-se que o motivo dessa valorização está na perspectiva da formação integral assumida por essas teorias e na concepção de conhecimento própria da lógica materialista dialética, nas quais elas se fundamentam. O ato de conhecimento, de acordo com essa lógica, envolve a abstração, generalização, análise e síntese como processos do pensamento. Assim, conhecer não se restringe à verbalização do conteúdo, mas a unidade do pensamento e da palavra, o que resulta no desenvolvimento do psiquismo humano. Os conceitos científicos estão vinculados a um tipo de pensamento específico, o pensamento teórico, que é desenvolvido por meio da aprendizagem desses conceitos articulados aos processos de pensamento que lhes são próprios. Conclui-se que no campo pedagógico, a valorização do ensino de conceitos científicos deve ser acompanhada de uma visão geral da teoria, o que permite ao professor redimensionar o modo de pensar e atuar com os conceitos nas situações de ensino, aproximando a aprendizagem dos estudantes ao potencial formativo exposto teoricamente.

Os projetos de pesquisa de Iniciação Científica, de Extensão e de Mestrado Profissional articularam-se, produzindo ações e reflexões a fim de verificar as possíveis contribuições do Yoga para profissionais de educação de uma rede municipal pública de ensino durante a pandemia de Covid-19. Nossas bases teóricas se assentaram no conceito de Autopoiésis (MATURANA e VARELA), no processo de produção da Tecnologia Social (RODRIGUES e BARBIERI), na tecnologia oriental (FEUERSTEIN) e na proposta de inovação pedagógica (CUNHA). As aulas de Yoga foram alicerçadas na escola do Yoga Integral de Sri Aurobindo, seguindo os oito pilares do Yoga Clássico, codificados por Patanjali e buscando focar na inclusão e na conexão Ocidente-Oriente. Realizamos pesquisa qualitativa e percorremos os princípios metodológicos da Pesquisa-ação (THIOLLENT) para superar as fronteiras entre sujeitos pesquisadores e pesquisados. Como resultados, obtivemos: um elevado número de artigos sobre o Yoga nas bases de dados científicas; um levantamento de opiniões de participantes sobre o estresse gerado pelas demandas profissionais em contato com as tecnologias informacionais durante o período de trabalho remoto; a oferta de aulas de Yoga on-line; os relatos dos participantes sobre os efeitos positivos das vivências para a saúde e para o processo de ressignificação do ser e do profissional de educação; e a geração de política de educação municipal por meio de um projeto permanente de yoga na rede pública municipal de educação.

Published: March 2024

O Sistema Nacional de Atendimento Socioeducativo (SINASE), que está em vigor desde 2006, veio reafirmar as diretrizes do Estatuto da Criança e do Adolescente (ECA) sobre a natureza pedagógica das medidas socioeducativas, sendo atualmente, o documento que fornece os parâmetros para o atendimento dos adolescentes em conflito com a lei, desde o processo de apuração, aplicação e execução de medidas socioeducativas. O presente estudo investigou o impacto da medida socioeducativa de Liberdade Assistida na auto-organização das perspectivas em médio e longo prazo de adolescentes autores/as de ato infracional. Trata-se de um estudo de natureza qualitativa, de caráter descritivo-exploratório com a colaboração de 13 adolescentes, com idade entre 12 e 18 anos incompletos. Os dados foram coletados por meio de um questionário de caracterização sociofamiliar e entrevistas individuais com roteiro semiestruturado, as quais foram gravadas e transcritas integralmente. O roteiro de entrevista contemplou questões norteadoras, as quais abordaram as experiências vivenciadas pelos/as adolescentes durante e depois do cumprimento da medida socioeducativa. Os resultados apontaram categorias significativas para auto-organização dos/as adolescentes na ocasião da medida e, neste texto, o foco está na categoria: Vínculos familiares e afetivos. Constatou-se, nesta pesquisa, que o arranjo familiar impacta substancialmente nas trilhas que os e a jovem optam, pois se configuram como limitadoras de oportunidades, pela falta de referências positivas sobre condutas socialmente aceitas e desejadas. Por outro lado, evidencia a responsabilidade que os avós assumem na educação dos netos/as, mas que há um conflito geracional entre anseios e perspectivas para viver o hoje e projetar o amanhã.

Authors: Elias Henrique Rizek , Sachs Línlya
Published: March 2024

O objetivo desta pesquisa é identificar subdomínios do Conhecimento Matemático para o Ensino mobilizados por meio da prática de escrita realizada por professores em uma disciplina de um curso de mestrado profissional em Ensino de Matemática. A disciplina contou com a participação de dez professores que atuam na Educação Básica. As práticas de escrita analisadas se deram em dois fóruns de discussões realizados em um ambiente virtual de aprendizagem e em uma atividade de autoavaliação realizada por uma professora participante. Com base no quadro teórico do Conhecimento Matemático para o Ensino (MKT), proposto por Deborah Ball e colaboradores, foi possível identificar que todos os subdomínios do MKT foram mobilizados durante as discussões nos fóruns e, no caso da autoavaliação, alguns subdomínios foram mais evidentes, como o Conhecimento do Conteúdo no Horizonte. Conclui-se que as atividades assíncronas, especialmente o fórum, permitem que os participantes, além de praticarem a escrita, organizem seus pensamentos antes de escrever, busquem referenciais teóricos para fundamentar suas afirmações e consultem seus alunos da Educação Básica para enriquecer as discussões. Por fim, sugere-se que as escritas dos professores, quando intencionalmente organizadas levando-se em consideração os subdomínios identificados, podem ser utilizadas em processos de formação inicial ou continuada de professores que ensinam Matemática.

O objetivo do trabalho foi compreender como os(as) professores(as) de Matemática do Ensino Básico do município de Itacoatiara-AM, que participaram do Programa Nacional de Formação de Professores da Educação Básica (PARFOR), produziram e/ou mobilizaram seus saberes docentes. Visando responder “como os (as) professores (as) de Matemática do Ensino Básico, do município de Itacoatiara-AM, se desenvolveram profissionalmente, produziram e/ou mobilizaram os saberes docentes ao participar do Programa PARFOR?” - e defender a tese que os(as) professores(as) de Matemática perceberam tanto contribuições como limitações da formação ofertada pelo PARFOR, que impactaram seu desenvolvimento profissional e influenciaram na produção e mobilização de seus saberes docentes. O referencial adotado se apoia na constituição dos saberes necessários e/ou conhecimento especializado do(a) professor(a) de Matemática. A metodologia foi um Estudo de Caso, com uma abordagem qualitativa, com: pesquisa documental sobre o Programa; entrevistas semiestruturadas com um coordenador institucional, quatro professores(as) formadores(as) e cinco professores(as) egressos(as); questionários eletrônicos; narrativas autobiográficas; observação de aulas on-line; plano de aulas e/ou sequências didáticas; avaliação de conhecimento especializado com dez professores(as) cursistas; diário de bordo da pesquisadora. A análise interpretativa apresentou como foco a triangulação dos dados mediante a construção de categorias decorrentes do confronto com os referenciais teóricos sobre saberes docentes e conhecimento especializado do professor de Matemática. Os resultados indicaram que, apesar das dificuldades e limitações apresentadas, os(as) professores(as) construíram e/ou mobilizaram seus saberes durante sua formação e no exercício da docência aos quais constituíram indicadores de desenvolvimento profissional expressados no seu conhecimento especializado e em suas práticas pedagógicas.

O artigo traz um recorte de uma pesquisa de doutorado que visa compreender o sistema de documentação de professores(as) que ensinam matemática em turmas da Educação de Jovens e Adultos do Campo, e a relação com os ambientes de aprendizagem propostos por eles(as). Trata-se da ampliação de um artigo publicado no VIII Seminário Internacional de Pesquisas em Educação Matemática, que apresenta uma caracterização de recursos utilizados por um professor da referida modalidade para ensinar matemática, busca classificá-los como materiais e não materiais e analisa as relações entre eles. A ampliação consiste na apresentação e na análise dos recursos utilizados também por uma professora na retomada do ensino presencial após o ensino remoto vivenciado durante a pandemia da Covid-19. A pesquisa ancora-se na metodologia da investigação reflexiva para realizar entrevistas semiestruturadas com esses professores, solicitar que produzissem um vídeo para apresentar os recursos disponíveis nas escolas e que utilizavam para ensinar matemática e, depois disso, construir uma representação esquemática de tais recursos. As análises dos dados produzidos revelam que a maioria dos recursos utilizados pelo professor está associada a objetos do dia a dia, ao passo que, entre os utilizados pela professora, prevaleceram aqueles associados às Tecnologias da Comunicação e Informação, o que pode denotar a influência do ensino remoto. Observa-se, também, uma preocupação de ambos em relacionar alguns recursos às realidades dos(as) estudantes da Educação de Jovens e Adultos do Campo, mesmo que não seja um aspecto predominante nos dados analisados.
Massive localized lymphedema of the thigh: Pseudosarcoma of the morbidly obese
Authors: ZSM Husain , ASA Driweesh
Published: March 2024

Massive localized lymphedema (MLL) is a recently described clinical condition characterized by lymphedema resulting from focally disrupted lymphatic drainage in morbidly obese patients. These patients typically present with long-standing, painless, slow-growing, ill-defined soft tissue masses. The masses are often found in the inner thigh and may resemble liposarcoma both clinically and histologically. Due to its challenging imaging characteristics, MLL poses diagnostic difficulties for clinicians and pathologists. As the global obesity epidemic persists, the incidence of MLL is expected to rise, necessitating awareness and appropriate management strategies. In this context, we present a case of MLL affecting the thigh in a morbidly obese patient. The final diagnosis was given based on patient’s demographics and the presence of lymphedema in other parts of the body.

One of the rare causes of PTH-independent hypercalcemia can be anabolic oil solution, injected intramuscularly by bodybuilders, along with anabolic hormones, in order to make the muscles more prominent. Here is the clinical report of a 43-year-old patient who used Synthol oil solution at the age of 25–30 years is presented. He had long-term undiagnosed hypercalcemia that manifested with nephrolithiasis and progressing chronic kidney disease (CKD). For the first time hypercalcemia was diagnosed at the age of 37, but left omitted. In 2023 (43 years) the laboratory findings sowed extremely high calcium level (4.26 mmol/l) with decreased PTH and CKD C4. Malignancy hypercalcemia was excluded. With this case, the rare cause of hypercalcemia has been proven – intramuscular oil injection resulting in nephrolithiasis, nephrocalcinosis and CKD. Treatment with glucocorticoids has demonstrated positive effect, similar to the ones of granulomatous diseases and hypercalcemia. The mechanisms of PTH-independent hypercalcemia development and differential diagnosis are currently being discussed. The presented clinical case of a rare cause of hypercalcemia may be useful for doctors of various specialties: endocrinologists, therapists, urologists, dermatologists, etc.

Published: March 2024

The department of counseling services at Kerobokan Prison, Bali, Indonesia reported to the researcher of this study that some of their inmates experienced psychological complaints which were impacting their physical health. The researcher conducted this study with the aim of providing a means of relief for the inmates, as well as to examine the impact of a Psycho-Spiritual Integrative Therapy (PSIT) as an intervention. A qualitative research method was used with a multiple case study approach with a thematic analysis to determine the influence of the intervention on the participants’ sense of life aspiration and psychological well-being. Fifteen male prisoners, who were serving 10 or more years for drug related offenses, completed the PSIT and participated in a post interview. The researcher found 5 main themes related to the participants’ experiences over the course of the intervention, which were regret, forgiveness, acceptance, belief, and affirmation. The participant reports indicate the beginning of a transformative change in perspective which may be beneficial for creating a new life for themselves upon their release from prison. Further research is necessary to assess long-term changes in the participants’ perspectives, and how they have integrated their awareness for their return to society. The findings of this research may be included into a residential health services module for the counseling services department at Kerobokan Prison, as well they may be influential in further public health research

Różewicz (zre)konstruowany?
Authors: Pietrych Krystyna
Published: March 2024

Artykuł jest recenzją książki Magdaleny Grochowskiej Różewicz. Rekonstrukcja. I, stanowiącej jedynie pierwszą cześć szeroko zakrojonego projektu biograficznego autora Kartoteki, która ukazała się w roku stulecia urodzin Tadeusza Różewicza. Recenzja prezentuje zamysł kompozycyjny biografii oparty zasadniczo na porządku chronologicznym (od narodzin do ok. 1957 roku), traktowanym jednak przez biografistkę swobodnie, bo nierzadko porzucanym na rzecz ujęć tematyczno-problemowym (np. kwestia żydowskiego pochodzenia, relacja z matką i żoną, akowska przeszłość i jej związek z późniejszą dramaturgią). Krytycznemu namysłowi została poddana strategia stosowana przez autorkę książki - nazbyt prostego łączenia plany i twórczości poprzez wykorzystanie utworów literackich w funkcji bezpośredniego komentarza do egzystencji poety. Zwrócono także uwagę na niewątpliwe atuty publikacji – wykorzystanie rezultatów pracy w archiwach, a także świetny reporterski warsztat Grochowskiej.
