Authors: Kang Yacheng , Liu Chang , Shao Lijing
Published: November 2021

Recently, Tamanini & Danielski discussed the possibility of detecting circumbinary exoplanets (CBPs) orbiting double white dwarfs (DWDs) with the Laser Interferometer Space Antenna (LISA). Extending their methods and criteria, we discuss the prospects for detecting exoplanets around DWDs not only by LISA, but also by Taiji, a Chinese space-borne gravitational-wave (GW) mission that has slightly better sensitivity at low frequencies. We first explore how different binary masses and mass ratios affect the abilities of LISA and Taiji to detect CBPs. Second, for certain known detached DWDs with high signal-to-noise ratios, we quantify the possibility of CBP detections around them. Third, based on the DWD population obtained from the Mock LISA Data Challenge, we present basic assessments of the CBP detections in our Galaxy during a 4 yr mission time for LISA and Taiji. We discuss the constraints on the detectable zone of each system, as well as the distributions of the inner/outer edge of the detectable zone. With the DWD population, we further inject two different planet distributions with an occurrence rate of 50% and constrain the total detection rates. We briefly discuss the prospects for detecting habitable CBPs around DWDs with a simplified model. These results can provide helpful inputs for upcoming exoplanetary projects and help analyze planetary systems after the common envelope phase.
Spatial and Kinematic Clustering of Stars in the Galactic Disk
Authors: Kamdar Harshil , Conroy Charlie , Ting 丁源 Yuan-Sen 森 , El-Badry Kareem
Published: November 2021

The Galactic disk is expected to be spatially and kinematically clustered on many scales due to both star formation and the Galactic potential. In this work we calculate the spatial and kinematic two-point correlation functions (TPCF) using a sample of 1.7 × 106 stars with radial velocities from Gaia DR2. Clustering is detected on spatial scales of 1–300 pc and a velocity scale of 15 km s−1. After removing bound structures, the data have a power-law index of γ ≈ −1 for 1 pc < Δr < 100 pc and γ ≲ −1.5 for Δr > 100 pc. We interpret these results with the aid of a star-by-star simulation of the Galaxy, in which stars are born in clusters orbiting in a realistic potential that includes spiral arms, a bar, and giant molecular clouds. We find that the simulation largely agrees with the observations at most spatial and kinematic scales. In detail, the TPCF in the simulation is shallower than the data at ≲20 pc scales, and steeper than the data at ≳30 pc. We also find a persistent clustering signal in the kinematic TPCF for the data at large Δv (>5 km s−1) that is not present in the simulations. We speculate that this mismatch between observations and simulations may be due to two processes: hierarchical star formation and transient spiral arms. We also predict that the addition of ages and metallicities measured with a precision of 50% and 0.05 dex, respectively, will enhance the clustering signal beyond current measurements.
Generation of Short-scale Electrostatic Fields in the Solar Atmosphere and the Role of Helium Ions
Authors: Saleem H. , Shan Shaukat Ali , Rehman A.
Published: November 2021

Theoretical models are presented to show that expansion of plasma in the radial direction from a denser solar surface to a rarefied upper atmosphere with short-scale inhomogeneous field-aligned flows and currents in the form of thin threads itself is an important source of electrostatic instabilities. Multifluid theory shows that the shear flow–driven purely growing electric fields appear in the transition region. On the other hand, plasma kinetic theory predicts that the short-scale current sheets (or filaments) produce current-driven electrostatic ion acoustic (CDEIA) waves in the hydrogen plasma of the transition region that damp out in the system through wave–particle interactions and increase the temperature. Similar processes take place in the solar corona and act positively for increasing the temperature further and maintaining it. The shear flow–driven instabilities and CDEIA waves have short perpendicular wavelengths of the order of 1 m and low frequencies of the order of 1 or several Hz when the ions’ shear flow scale length is considered to be of the order of 1 km. It is pointed out that the purely growing fluid instabilities turn into oscillatory instabilities and the growth rates of kinetic CDEIA wave instabilities are reduced when the dynamics of 10% helium ions is taken into account along with 90% hydrogen ions. Therefore, the role of helium ions should not be ignored in the study of wave dynamics in solar plasma.
High-energy Neutrinos from Magnetized Coronae of Active Galactic Nuclei and Prospects for Identification of Seyfert Galaxies and Quasars in Neutrino Telescopes
Authors: Kheirandish Ali , Murase Kohta , Kimura Shigeo S.
Published: November 2021

Particles may be accelerated in magnetized coronae via magnetic reconnections and/or plasma turbulence, leading to high-energy neutrinos and soft γ-rays. We evaluate the detectability of neutrinos from nearby bright Seyfert galaxies identified by X-ray measurements. In the disk-corona model, we find that NGC 1068 is the most promising Seyfert galaxy in the Northern sky, where IceCube is the most sensitive, and show prospects for the identification of aggregated neutrino signals from Seyfert galaxies bright in X-rays. Moreover, we demonstrate that nearby Seyfert galaxies are promising targets for the next generation of neutrino telescopes such as KM3NeT and IceCube-Gen2. For KM3NeT, Cen A can be the most promising source in the Southern sky if a significant fraction of the observed X-rays come from the corona, and it could be identified in few years of KM3NeT operation. Our results reinforce the idea that hidden cores of supermassive black holes are the dominant sources of the high-energy neutrino emission and underlines the necessity of better sensitivity to medium-energy ranges in future neutrino detectors for identifying the origin of high-energy cosmic neutrinos.
Galaxy Core Formation by Supermassive Black Hole Binaries: The Importance of Realistic Initial Conditions and Galaxy Morphology
Authors: Dosopoulou Fani , Greene Jenny E. , Ma Chung-Pei
Published: November 2021

The binding energy liberated by the coalescence of supermassive black hole (SMBH) binaries during galaxy mergers is thought to be responsible for the low density cores often found in bright elliptical galaxies. We use high-resolution N-body and Monte Carlo techniques to perform single and multistage galaxy merger simulations and systematically study the dependence of the central galaxy properties on the binary mass ratio, the slope of the initial density cusps, and the number of mergers experienced. We study both the amount of depleted stellar mass (or mass deficit), M
def, and the radial extent of the depleted region, r
b. We find that r
b ≃ r
SOI and that M
def varies in the range of 0.5–4M
•, with r
SOI the influence radius of the remnant SMBH and M
• its mass. The coefficients in these relations depend weakly on the binary mass ratio and remain remarkably constant through subsequent mergers. We conclude that the core size and mass deficit do not scale linearly with the number of mergers, making it hard to infer merger histories from observations. On the other hand, we show that both M
def and r
b are sensitive to the morphology of the galaxy merger remnant, and that adopting spherical initial conditions, as done in early work, leads to misleading results. Our models reproduce the range of values for M
def found in most observational work, but span nearly an order-of magnitude range around the true ejected stellar mass.

Advances in cosmic microwave background (CMB) science depend on increasing the number of sensitive detectors observing the sky. New instruments deploy large arrays of superconducting transition-edge sensor (TES) bolometers tiled densely into ever larger focal planes. High multiplexing factors reduce the thermal loading on the cryogenic receivers and simplify their design. We present the design of focal-plane modules with an order of magnitude higher multiplexing factor than has previously been achieved with TES bolometers. We focus on the novel cold readout component, which employs microwave SQUID multiplexing (μmux). Simons Observatory will use 49 modules containing 70,000 bolometers to make exquisitely sensitive measurements of the CMB. We validate the focal-plane module design, presenting measurements of the readout component with and without a prototype detector array of 1728 polarization-sensitive bolometers coupled to feedhorns. The readout component achieves a 95% yield and a 910 multiplexing factor. The median white noise of each readout channel is 65

. This impacts the projected SO mapping speed by <8%, which is less than is assumed in the sensitivity projections. The results validate the full functionality of the module. We discuss the measured performance in the context of SO science requirements, which are exceeded.

In the article was studied the effects of flavonol quercetin on indices of adaptive immune response in experimental animals on the 14th day of the experimental bacterial-immune periodontitis development. Indices of immune protection were determined by the relative number of lymphocytes with CD3+, CD4+, CD8+, CD19+, CD16+ and immunoregulatory index (CD4+ / CD8+) in intact animals and on the 14th day of inflammatory process development in periodontal tissues as well as the therapeutic effects of flavonol quercetin. As a result of the study, characterized changes associated with the activity of both the cell-mediated and humoral-immune response were found, both in the development of experimental periodontitis, and apply of flavonol. In particular, there was an increase in the animal’s blood relative amount of CD8+, CD16+ cells on the 14th day, and content of CD3+, CD4+, CD19+ was decreased. In this case, the immunoregulatory index (CD4+ / CD8+) as an important index of immunological activity was decreased. The apply of flavonol quercetin in the period development of bacterial-immune periodontitis animals functional activity of the T-cell line of the immune system was increased, as evidenced percentage increase of B- and T-cells due to T-helper cells decrease as well as T-killers content during this period of inflammatory reaction in the periodontal complex, in comparison with animals, which were not treated.

La double naissance de la clinique. Numérisation des données médicales au XIX e siècle

Published: November 2021

« Et si la médecine clinique, que Michel Foucault fait naître au croisement de la doctrine sensualiste et de la pratique anatomo-pathologique, avait éludé son lien à la méthode numérique, son histoire, déjà traversée d’accidents, détournée et retardée par de multiples discours, ne prendrait-elle pas un sens nouveau ? Aussi, avant que le pouvoir des grands nombres n’intronise la méthode numérique en tant que forme majoritaire, cette dernière fut rendue minoritaire par le pouvoir des grands noms de la médecine du xix e  siècle.

A new dynamic model to optimize the reliability of the series-parallel systems under warm standby components
Authors: Saghih Amir Mohammad Fakoor , Modares Azam
Published: November 2021

Redundancy allocation problem (RAP) is a common technique for increasing the reliability of systems. In this paper, a new model for the RAP is introduced that takes into account the warm standby and mixed strategy, the model dynamics, and the type of the strategy in redundancy allocation problems. A recursive formula is first obtained for the reliability function in the dynamic warm standby and mixed redundancy strategies that leverages the success mode analysis and works for any arbitrary failure-time distribution. Failure rates for warm standby units change before and after their replacement with a damaged unit, and, therefore, the reliability function in warm standby varies with time (i.e., the model is dynamic). Although dynamic models are commonplace in practice, they are more challenging to assess than static models, which have been mainly considered in the literature. An optimization problem is then formulated to select the best redundancy strategy and redundancy levels. Genetic algorithm and particle swarm optimization are leveraged to solve the problem. Finally, the efficiency of the presented method is verified through a numerical example. The experimental results verify that the proposed model for RAP significantly improves the system reliability, which can be of vital importance for system designers.

Published: November 2021

Memoryless quasi–Newton updating formulas of BFGS (Broyden–Fletcher–Goldfarb–Shanno) and DFP (Davidon–Fletcher–Powell) are scaled using well-structured diagonal matrices. In the scaling approach, diagonal elements as well as eigenvalues of the scaled memoryless quasi–Newton updating formulas play significant roles. Convergence analysis of the given diagonally scaled quasi–Newton methods is discussed. At last, performance of the methods is numerically tested on a set of CUTEr problems as well as the compressed sensing problem.
Prevalence of vector borne diseases in Jammu Division, Jammu and Kashmir, India
Authors: Jamwal Neha , Bhatia Sanjay
Published: November 2021

Background & objectives: Jammu and Kashmir is bestowed upon by great climatic condition favourable for people but the vectors have utilised these conditions to gain access into the state. Vector Borne Diseases (VBDs) were restricted to the spread of malaria and dengue since past two decades, but now, these diseases have widened their geographical reach and in last six years chikungunya, leishmaniasis and Japanese encephalitis have been reported from the state. These VBDs are a threat to thousands of people in the state as they cause huge mortality and morbidity under extreme cases.

Methods: A hospital-based survey on the VBDs was carried out with the aim of studying the prevalence of major VBD found in the Jammu district taking into account the past records provided by the Directorate of Health Services, Jammu.

Results: The study revealed that malaria, in the past 14 years, has now shown a clear declining trend and dengue cases have shown a very uneven trend with maximum cases in 2013. Leishmaniasis was reported for the first time in the division in 2013, while it was not until 2016 when single case of chikungunya was reported from Jammu division. First outbreak of Japanese encephalitis in the region occurred during 2018 from only Doda district.

Interpretation & conclusion: The present study showed that despite having congenial environmental conditions, Jammu division faces a great threat of VBDs and the increase in the number of cases in future cannot be ruled out. Japanese encephalitis registered its presence for the first time in the division.
Rehabilitation after Forearm/Hand Replantation

Published: November 2021

Currently, the challenge of replantation of the upper limb after amputation has become an achievable and meticulously perfected reality in recent decades and is in constant evolution. The surgical option for replantation should take into account not only a comprehensive analysis of the viability of the replantation but fundamentally its potential for long-term functional recovery. We present the clinical case of a 40-year-old man, victim of a work accident, with cut trauma, which resulted in distal amputation of his right forearm. The warm ischemia time was 5 h, having been submitted to joint replantation surgery. Following the surgery, physical medicine and rehabilitation (PMR) was referred early, carrying out a sequential functional rehabilitation program. This work aims to emphasize the importance of the role of PMR in an early, careful, and extensive rehabilitation program, a fundamental factor in the functional recovery and long-term prognosis of these injuries and prevention of complications.
Geochemical and isotopical variations within the Campanian Comagmatic Province: implications on magma source composition
Authors: Monica Piochi  , Lucia Pappalardo  , Gianfilippo De Astis
Published: November 2021

A spatial variation in chemical and isotopical composition is observed between the volcanoes belonging to the Campanian Comagmatic Province. At a given MgO content, magmas from volcanic islands (Procida and Ischia) are enriched in Ti, Na, depleted in La, Ba, Rb, Sr, Th, K contents, and shows lower LREE/HFSE (e.g., La/Nb = = 1-2), lower Sr-Pb isotopic ratios and higher Nd isotopic ratios with respect to magmas from volcanoes locat- ed inland (Campi Flegrei and Somma-Vesuvius). The observed compositional variations are explained involving two different mantle sources in the genesis of the magmas erupted in this region: a deeper asthenospheric man- tle source, from which the Tyrrhenian magmas also derived and a lithospheric mantle source enriched by slab- derived fluids. The contribution of the enriched-lithospheric mantle became more pronounced moving from the Tyrrhenian abyssal plain through the Italian Peninsula where it dominates, likely in response to the thickening of the lithosphere observed under the Peninsula
A Solution to Design Semi-static Null Convention Logic Cell Libraries
Authors: Tri Lac Truong , Thanh Toi Le , Hoang Trang
Published: November 2021

The Null Convention Logic (NCL) based asynchronous circuits have eliminated the disadvantages of the synchronous circuits, including noise, glitches, clock skew, power, and electromagnetic interference. However, using NCL based asynchronous designs was not easy for students and researchers because of the lack of standard NCL cell libraries. This paper proposes a solution to design a semi-static NCL cell library used to synthesize NCL based asynchronous designs. This solution will help researchers save time and effort to approach a new method. In this work, NCL cells are designed based on the Process Design Kit 45nm technology. They are simulated at the different corners with the Ocean script and Electronic Design Automation (EDA) environment to extract the timing models and the power models. These models are used to generate a *.lib file, which is converted to a *.db file by the Design Compiler tool to form a complete library of 27 cells. In addition, we synthesize the NCL based full adders to illustrate the success of the proposed library and compare our synthesis results with the results of the other authors. The comparison results indicate that power and delay are improved significantly.

Authors: Sara Dem Vi , Maharani MDD , Amin Hafiza Farwa , Triana Yaya Sudarya
Published: November 2021

Climate change could lead to an increase in diseases in plants and animals. Plant pathogens have caused devastating production losses, such as in tropical countries. The development of algorithms that match the accuracy of plant and animal disease detection in predicting the toxicity of substances has continued through a massive database. Data and information from 10,000 substances from more than 800,000 animal tests have been carried out to generate the algorithms. Plant and animal disease detection using artificial intelligent in the modern ecological era is important and needed. Diseases in animals are still found in several Ruminant-Slaughterhouses. The purpose of the study is to identify the leverage attributes for using of Artificial Intelligent (AI) in detecting plant pests and animal diseases. The use of Multidimensional Scaling (MDS) produces a leverage attribute for the use of AI in detecting plant pests and animal diseases. The results showed that leverage attributes found were: Prediction of the presence of proteins structures produced by pathogens with a Root Mean Square (RMS) value of 4.5123; and Plant and Animal Disease Data will be opened with an RMS value of 4.2555. The findings of this study in the real world are to produce the development of smart agricultural applications in detecting plant pests and animal diseases as an early warning system. In addition, the application is also useful for eco-tourism managers who have a natural close relationship with plants and animals, so that ecological security in the modern ecological era, can be better maintained.
Morphological variability of Douglas fir (Pseudotsuga menziesii (Mirb.) Franco) cones in the context of seed extraction
Authors: Gendek Arkadiusz , Aniszewska Monika , Tulska Ewa , Siwek Joanna
Published: November 2021

In the paper generating curves given by fourth-degree polynomials were used to model the shape of Douglas fir (Pseudotsuga menziesii (Mirb.) Franco) cones from the Polish Forest Districts of Kołaczyce (one batch) and Opole (two batches), and to calculate the surface area and volume of individual cones. However, it was not possible to construct generalized equations for the surface area and volume of Douglas fir cones due to the high variability of empirical coefficients. The surface area and volume of the cones were also calculated from their length and diameter based on formulas for a cylinder and a barrel corrected by constants k1 and k2. The mean surface area of closed Douglas fir cones determined for the first, second, and third batch using the generating function was 4,348.4 mm2, 3,857.0 mm2, and 2,844.7 mm2, and the volume was 27,212.4 mm3, 21,012.9 mm3, and 12,844.4 mm3, respectively. The corresponding values calculated from the geometric formulas for solids were 4,332.0 mm2, 3,838.0 mm2, and 2,862.9 mm2 for the surface area and 27,366.0 mm3, 20,648.9 mm3, and 13,375.3 mm3 for the volume. The evaporation area of open cones was found to be five times greater than that of closed cones, with the difference being statistically significant. The outer and inner surfaces of scales taken from the middle segment of Douglas fir cones were photographed using a Quanta 200 scanning microscope (FEIC). The characteristic elements of scale morphology were evaluated by means of MultiScan Base software package. The outer and inner surfaces of Douglas fir scales were found to differ in some important ways, similarly as it has been reported in the literature for the Scots pine, silver fir, European larch, and black alder. The outer surface of scales is formed by thick-walled cells with marked protrusions, while the inner surface reveals cells with thin, frayed walls in the region adjacent to the seeds and wings. Knowledge of the geometry of Douglas fir cones and the morphology of their scales may be helpful in optimizing seed extraction parameters for those cones. Key words: seed extraction, model, shape curve, surface area, volume, scanning electron microscope
Neuropatia de fibras finas: uma visão geral
Authors: Barbosa Luciana Mendonça , Andrade Daniel Ciampi A. de
Published: November 2021

A neuropatia de fibras finas (NFF) é definida pelo comprometimento primordial de fibras pouco mielinizadas e não mielinizadas, as quais medeiam a sensibilidade térmica e dolorosa, bem como informações e respostas autonômicas. Ela pode estar presente em diversas apresentações espaciais, como a NFF localizada, que ocorre em alguns casos de doença de Hansen, ou a NFF que segue um padrão de polineuropatia e que pode acometer partes extensas do corpo.
Reconhecer clinicamente um quadro de neuropatia e classificá-lo de acordo com a modalidade de fibras comprometidas – finas sensitivas, autonômicas, grossas sensitivas, motoras ou uma combinação – é importante para direcionar as hipóteses diagnósticas, os exames subsidiários a serem solicitados e o tratamento.
Embora cerca de um terço dos casos não possua etiologia definida, entre as causas principais estão diabetes, intolerância à glicose, doenças inflamatórias e imunomediadas, como síndrome de Sjögren (SS), lúpus eritematoso sistêmico (LES), artrite reumatoide e sarcoidose, doenças hereditárias, amiloidose, causas infecciosas, como pelo vírus da imunodeficiência humana (HIV), hepatite C, além de doenças carenciais e tóxicas, como as relacionadas ao uso de álcool e quimioterápicos, entre outras.
O diagnóstico é realizado com base na história detalhada e no exame físico. Existem exames subsidiários, como o Teste Quantitativo Sensorial (TQS), a biópsia de pele com contagem da densidade de fibras nervosas intraepidérmicas e outros testes que ainda requerem validação.
O diagnóstico da NFF é fundamental, pode ser a primeira manifestação de quadros inflamatórios, imunomediados, infecciosos, metabólicos ou tóxicos, além de os sintomas, como dor, serem muitas vezes incapacitantes.

Computer Simulation Integration in Secondary Physics
Authors: Abiasen Jovalson , Reyes Gaudelia
Published: November 2021

This paper explored the teaching experiences of physics teachers in integrating computer simulations in their pedagogy to promote a constructivist learning environment. Its objectives are to determine how physics teachers describe computer simulations based on how they are used, how these are embedded in the teaching-learning process, their impact on the teaching-learning process, and the challenges of integrating these into physics teaching. Using the phenomenological design, two themes emerged for the first objectives, which are process-based and system-based. First, the teacher-manipulated with sub-themes of engaging, demonstrating, elaborating, and evaluating, and student-manipulated emerged on how the simulations are used. Second, the impact to teaching generated knowledge-based, skill-based, and value-based learning-based primarily on the three learning domains. Also, respondents emphasized that the integrations of computer simulations are convenience, efficacy, and heterogeneity. Finally, the challenges in the integration process are classified as teacher and school-related.  The results showed that teachers are integrating computer simulations differently depending on their resources and the TPACK knowledge.

Published: November 2021

O objetivo deste artigo é analisar o conceito de políticas públicas de forma estruturada, para permitir sua compreensão sistêmica a partir do Estado da Questão (EQ), elaborado no recorte temporal compreendido entre 2006 e 2020, nas publicações em periódicos qualificados. Trata-se de pesquisa bibliográfica de abordagem qualitativa, tendo como foco abrangente a categoria política pública. Para subsidiar o diálogo conceitual abordou-se como a literatura revisada trata o conceito de políticas públicas, suas especificidades e perspectivas enquanto campo de conhecimento científico alcançando suas distintas categorias, tipologias e dimensões essenciais, o que permitiu delimitar o alcance do EQ e a construção do objeto investigado. Constatou-se o dissenso entre os pesquisadores quanto a parte conceitual e constitutiva da temática. Assim, conclui-se, que as políticas públicas se apresentam como mecanismos estratégicos, orientadores da relação entre o ente público e a sociedade, sobretudo, na dinâmica estabelecida em seus subsistemas que inclusive impactam seus resultados.

Challenges in lifestyle, such as increasesin energy intake and decreasesin physical activity are causing overweight and
obesity leading to epidemic increases in type II Diabetes Mellitus. The research approach used for this study was
evaluative approach and the research design was true experimental design. 60 patients with type II diabetes, 30 in
experimental group and 30 in control group were selected for this study by using purposive sampling technique. Data
was collected with the help of self-structured interview schedule. Descriptive statistics (frequency, percentage, mean
and standard deviation) and inferential statistics (chi-square, paired ‘t’ test) were used to analyse the data and to test
the hypotheses. In the experimental group,the pre-test mean score was 2.966, mean percentage was 59% and standard
deviation was 1.129 and in post-testmean score was 2.533, mean percentage was 50.66% and standard deviation was
1.074 with effectiveness of 8.34% and paired‘t’ test value of t=3.971,which was statistically significant (p<0.05) which
is an evidence ofthe effectiveness of Amla juice in reducing blood glucose level. Comparison of blood glucose levels in
experimental and control groups, shows that the value is statistically highly significant, as was observed from the
unpaired ‘t’ test value of 13.39 with P value of <0.05, which is an evidence indicatingthe effect of Amla juice in reducing
postprandial blood glucose levels. The resultsfound that the administration of Amla juice did have aneffect in reducing
blood glucose level in the experimental group. By comparing the findings of pre-test and post test between the
experimental group and the control group,the effect was identified (assessed). The study concluded that the Amlajuice
is effective in reducing blood glucose level.

A kisebbségi nyelvvédelem normatív fejlődése Olaszországban
Authors: Szabó Orsolya Katalin
Published: November 2021

Olaszország az Európai Unió és a multilaterális kisebbségvédelmi egyezmények részes államaként köteles a nemzeti jogrendjében a nyelvi kisebbségek védelmét is biztosítani. A jelen tanulmány az olasz nyelvi kisebbségek helyzetével foglalkozik, lajstromba veszi mind az országban élő kisebbségi csoportokat, mind az azok jogi védelmét biztosító nemzeti és nemzetközi jogi aktusokat. Olaszország két szempontból is érdekes tesztalanya a kisebbségvédelmi törekvések vizsgálatának. Egyrészt az országot történelmi okokból egyedülálló nyelvi sokszínűség jellemzi, az olasz dialektusok és az újlatin nyelvek közötti határvonal meghúzása állandó vita tárgya a romanisztikában. Másrészt az ország ad otthont az autonómiatörekvések és a kisebbségvédelem nemzetközi példájaként számon tartott dél-tiroli kisebbségnek, ami az országot az utóbbi szempontjából a progresszív és fejlett állami jogalkotók közé sorolja, ugyanakkor ennek némileg ellentmond az a tény, hogy Olaszország továbbra sem ratifikálta az Európa Tanács égisze alatt 1992-ben elfogadott Regionális vagy kisebbségi nyelvek európai chartáját, a kisebbségi nyelvek nemzetközi védelmének legfontosabb keretszabályát. A tanulmány a vonatkozó nemzeti és nemzetközi jogforrások alapján megvizsgálja azt is, hogyan fejlődött a nyelvi kisebbségvédelmi politika az egységes olasz állam 1861-es megszületése óta, és milyen esetleges jövőbeli feladatok várnak a jogalkotókra.
As matemáticas lidas através de suas próprias palavras: uma cultura de tradução de textos originais de história da matemática
Authors: Cortese João F. N. , Bertato Fábio Maia
Published: November 2021

Discutir se a matemática constitui a “linguagem” da natureza é uma questão complexa. Saber se a Natureza seria um livro constituído por caracteres matemáticos, como queria Galileu ao situá-lo lado a lado com a Escritura, leva-nos a diversos problemas filosóficos, inclusive no que diz respeito às intrincadas relações entre a matemática e a física. Uma coisa, entretanto, é clara: ainda que se possa discutir em que sentido a matemática seria uma “linguagem”, ela certamente é passível, assim como as línguas naturais, de escrita, de leitura, de interpretação e de tradução. Não cabe aqui desenvolver uma hermenêutica ou uma semiótica das matemáticas (tarefa, aliás, que seria muito bem vinda); destaquemos apenas que, ao traduzir um autor, o tradutor nos abre caminho para que cheguemos mais próximos de um pensamento em sua versão original.

Published: November 2021

El objetivo del artículo es analizar las diferencias que presentan docentes mujeres y docentes hombres de la Universidad Nacional Autónoma de México (UNAM) ante el mandato de conciliar su trabajo académico y de cuidados en el contexto de la pandemia por Covid-19. Metodológicamente se trató de un estudio exploratorio cuyos datos se obtuvieron de un cuestionario de respuesta cerrada, el cual se aplicó en las últimas dos semanas de junio de 2020 sobre una muestra efectiva de 395 docentes mujeres y hombres de nivel medio superior y superior. Los resultados del análisis sugieren que las mujeres dedican más tiempo al trabajo de cuidados no remunerados, así como a las actividades que forman parte del trabajo académico comparado con los docentes hombres. La principal conclusión es que el orden de género y la distribución sexual del trabajo es un fenómeno que se reproduce en el ámbito de la docencia universitaria y continúa presente en la organización de las tareas docentes en el contexto de la pandemia.
