Error-Free Arduino Communication: Integrating Hamming Code for UART Serial Transmission
Authors: Raharjo Budi , Silalahi Fujiama Diapoldo
Published: August 2024

Serial communication is a fundamental method for data transfer in electronic devices, particularly in Arduino-based systems. However, existing protocols, such as Universal Asynchronous Receiver/Transmitter (UART), often lack robust error detection mechanisms, leading to potential data integrity issues. This study aims to address the knowledge gap regarding error detection in UART communication by implementing Hamming Code, a well-established method for detecting and correcting single-bit errors. The research employs a systematic approach, including data encoding before transmission and decoding with error correction at the receiver end. The results demonstrate that the integration of the Hamming Code significantly enhances the reliability of data transmission, reducing error rates and improving overall system performance. The implications of this research extend to various applications requiring high data integrity, such as industrial control systems and Internet of Things (IoT) devices. By providing a practical solution to the challenges of error detection in serial communication, this study contributes to the advancement of reliable communication systems in modern technology.
Utilizing phpMyAdmin for System Design in Enterprise Administration
Authors: Wibowo Mars Caroline , Wijanarko Adi Putra Toni
Published: August 2024

In today's digital landscape, effective data management is essential for organizations, particularly small and medium-sized enterprises (SMEs) that often struggle with traditional manual methods, leading to inefficiencies and data inaccuracies. This research aims to investigate the implementation of phpMyAdmin, a web-based database management tool, to enhance administrative systems within SMEs. The study employs a mixed-methods approach, integrating qualitative case studies and quantitative surveys to gather comprehensive insights into user experiences and operational performance. The findings reveal that the adoption of phpMyAdmin significantly improves data management efficiency, with 75% of respondents expressing satisfaction with its user-friendly interface. However, challenges such as security vulnerabilities and the necessity for user training were also identified, indicating that while phpMyAdmin offers substantial benefits, organizations must address these issues to fully leverage their capabilities. The implications of this research suggest that SMEs should prioritize investing in user training and implementing robust security measures to mitigate risks associated with data management. By doing so, organizations can enhance their operational efficiency and decision-making processes. Future research should focus on the long-term impacts of phpMyAdmin and explore its integration with other management systems to further optimize organizational performance.

Published: August 2024

Abstract. Madrid–Barajas Airport (MAD) is the fourth-busiest airport in Europe. The aerosol chemical composition and the concentrations of other key pollutants were measured at the airport perimeter during October 2021 to assess the impact of airport emissions on local air quality. A high-fidelity ambient instrumentation system was deployed at Madrid–Barajas Airport to measure the following: concentrations of organic aerosols (with their composition), black carbon (eBC), carbon dioxide (CO2), carbon monoxide (CO), nitrogen dioxide (NOx), sulfur dioxide (SO2), particulate matter (PM2.5, PM10), total hydrocarbon (THC), and total particle number. The average concentrations of eBC, NOx, SO2, PM2.5, PM10, CO, and THC at the airport for the entire campaign were 1.07 µg m−3, 22.7 µg m−3, 4.10 µg m−3, 9.35 µg m−3, 16.43 µg m−3, 0.23 mg m−3, and 2.30 mg m−3, respectively. The source apportionment analysis of the non-refractory organic aerosol (OA) using positive matrix factorisation (PMF) allowed us to discriminate between different sources of pollution, namely less oxidised oxygenated organic aerosol (LO-OOA), alkane organic aerosol (AlkOA), and more oxidised oxygenated organic aerosol (MO-OOA). The results showed that LO-OOA and MO-OOA account for more than 80 % of the total organic particle mass measured near the runway. Trace gases correlate better with the AlkOA factor than LO-OOA and MO-OOA, indicating that AlkOA is mainly related to primary combustion emissions. Bivariate polar plots were used for pollutant source identification. Significantly higher concentrations of the obtained factors were observed at low wind speeds (<3 m s−1) from the southwest, where two of the runways and all terminals are located. Higher SO2/NOx and CO/eBC ratios were observed when the winds originated from the northeast, where the two northern runways are located. These elevated ratios are attributed to the aircraft activity being the major pollutant source in the northeast area.
Number- and size-controlled rainfall regimes in the Netherlands: physical reality or statistical mirage?
Authors: Schleiss Marc
Published: August 2024

Abstract. An experimental study aimed at identifying special rainfall regimes with the help of co-located disdrometers is performed. Eight potentially special events (i.e., four number-controlled events and four size-controlled events) are identified and examined. However, a detailed cross-check with additional, independent radar measurements reveals no clear evidence of special rainfall dynamics. The research underscores the difficulty of experimentally confirming seemingly straightforward questions about rainfall patterns and dynamics that have been theorized in the literature for several decades but never formally validated experimentally. The study also questions the reliability of previous claims and serves as a reminder to approach such problems with more caution, emphasizing the need for rigorous uncertainty analysis and multiple cross-checks between sensors to avoid misinterpretation.
Empirical Modeling of Tropospheric Delays and Uncertainty
Authors: Wang Jungang , Chen Junping , Zhang Yize
Published: August 2024

Abstract. Accurate modeling of troposphere delay is important for high-precision data analysis of space geodetic techniques, such as the Global Navigation Satellite System (GNSS). The empirical troposphere delay models provide zenith delays with an accuracy of 3 to 4 cm globally and do not rely on external meteorological input. They are thus important for providing a priori delays and serving as constraint information to improve the convergence of real-time GNSS positioning, and in the latter case, the proper weighting is critical. Currently, the empirical troposphere delay models only provide the delay value, but not the uncertainty of the delay. For the first time, we present a global empirical troposphere delay model, which provides both the zenith delay and the corresponding uncertainty, based on 10 years of tropospheric delays from the Numerical Weather Model (NWM). The model is based on a global grid, and at each grid point a set of parameters that describes the delay and uncertainty by the constant, annual, and semi-annual terms. The empirically modeled zenith delay has an agreement of 36 and 38 mm compared to three years delay values from NWM and four years estimates from GNSS stations, which is comparable to the previous models such as GPT3. The modeled ZTD uncertainty shows a correlation of 96 % with the accuracy of the empirical ZTD model over 380 GNSS stations over the four years. For GNSS stations where the uncertainty annual amplitude is larger than 20 mm, the temporal correlation between the uncertainty and smoothed accuracy reaches 85 %. Using GPS pseudo-kinematic PPP solutions of ~200 globally distributed stations over four months in 2020, we demonstrate that using the proper constraints can improve the convergence speed. The uncertainty modeling is based on a similar dataset as the GPT series, and thus it is also applicable for these empirical models.
A new global marine gravity model NSOAS24 derived from multi-satellite sea surface slopes
Authors: Zhang Shengjun , Chen Xu , Zhou Runsheng , Jia Yongjun
Published: August 2024

Abstract. Judging from the early release of the NSOAS22 model, there were some known issues, such as boundary connection problems in block-wise solutions and a relatively high noise level. By solving these problems, a new global marine gravity model NSOAS24 is derived based on sea surface slopes (SSS) from multi-satellite altimetry missions. Firstly, SSS and along-track deflections of vertical (DOV) are obtained by retracking, resampling, screening, differentiating, and filtering procedures on basis of altimeter waveforms and sea surface height measurements. Secondly, DOVs with a 1'x1' grid interval are further determined by the Green's function method, which applies directional gradients to constrain the surface, least-square fit to constrain noisy points, and tension constraints to smooth the field. Finally, the marine gravity anomaly is recovered from the gridded DOV according to the Laplace Equation. Among the entire processing procedures, accuracy improvements are expected for NSOAS24 model due to the following changes, e.g., supplementing recent mission observations and removing ancient mission data, optimizing the step size during the Green's function method, and special handling in near-shore areas. These optimizations effectively resolved the known issues of signal aliasing and the “hollow phenomenon” in coastal zones. Numerical verification was conducted in three experimental areas (Mariana Trench area, Mid-Atlantic Ridge area, Antarctic area, representing low, mid and high latitude zones) with DTU21, SS V32.1 and shipborne data. Taking NSOAS22 for contrast, NSOAS24 showed improvements of 1.2, 0.7, 1.0 mGal in 3 test areas by validating with SS V32.1, while declines of 0.6, 0.5, 0.3 mGal, and 0.2, 0.4, 0.3 mGal occurred in STD statistics with DTU21 and shipborne data. Finally, the NSOAS24 was assessed using two sets of shipborne data (the early NCEI dataset and the lately dataset from JAMTEC, MGDS, FOCD, and SHOM) on global scale. Generally, NSOAS24(6.33 and 4.95 mGal) showed comparable accuracy level with DTU21 (6.20 and 4.71 mGal) and SS V32.1 (6.40 and 5.53 mGal), and better accuracy than NSOAS22 (6.64 mGal and 5.64 mGal). Besides, the new model is available at https://doi.org/10.5281/zenodo.12730119 (Zhang et al., 2024).
Mechanisms of surface solar irradiance variability under broken clouds
Authors: Mol Wouter , van Heerwaarden Chiel
Published: August 2024

Abstract. Surface solar irradiance variability is present under all broken clouds, but the patterns, magnitude of variability, and mechanisms behind it vary greatly with cloud type. In this study, we performed numerical experiments to understand which main mechanisms drive surface solar irradiance extremes across a diverse set of cloud conditions based on observations. The results show that we can capture the essence in four mechanisms. We find that for optically thin (τ < 6) and clouds, scattering in the forward direction (forward escape) is the dominant mechanism. In cloud types such as altocumulus, it is able to produce irradiance enhancements of up to 50 % of clear-sky values due to small gaps in the cloud field. For flat, optically thick clouds (τ > 6) like stratus, downward escape becomes the dominant mechanism, and the irradiance extremes are found underneath the cloud edge or gaps. Albedo has a significant effect under optically thick cloud cover, contributing 10 to 60 % of the total irradiance enhancement for low (0.2) to high (0.8) albedo. For deep convective clouds, side escape is the dominant mechanism enhancing domain-averaged diffuse irradiance. This effect has a large area of influence, extending over 20 km from the sunlit side of the cloud. Extreme irradiance enhancement, however, comes from downward escape and forward escape just underneath the cloud edge on the sunlit side, not from side escape. These results provide a framework for understanding the vast diversity and complexity found in surface solar irradiance and cloudiness. A next step is to apply this analysis to multi-layered cloud fields and non-isolated deep convective clouds.

Published: August 2024

Abstract. Long-lived atmospheric species like carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), and CFCs exhibit discernible trends reflecting anthropogenic emissions, with increases observed in CO2, CH4, N2O, and decreases in CFCs. Conversely, trends for short-lived species like carbon monoxide (CO) and nitrogen oxides (NOx) remain less understood due to rapid chemistry and limited upper tropospheric observations. We utilize extensive in-situ CO measurements spanning 2012–2023, supplemented by prior airplane campaigns from 1991–2019, to examine short-term fluctuations in CO influenced by anthropogenic emissions and rapid chemical removal. Comparisons with MOPITT satellite data and chemistry budgets from 1948–2003 simulations further elucidate the interplay of sources and sinks, revealing the significant impact of chemistry on CO profiles and trends.

Abstract. To understand the spatial variation of optical and structural properties of water-soluble brown carbon and its influencing factors in China, the light absorption, fluorescence, and Fourier transform infrared (FTIR) spectrum of water-soluble organic carbon (WSOC) in different regions of China are measured following the same analytical methods. The average light absorption coefficients and mass absorption efficiencies of WSOC at 365 nm (Abs365 and MAE365) rank from high to low as northwest China > southwest China > north China > east China > regional site, with higher values in Northern China than Southern China and regional sites, and higher values in inland areas than coastal areas. The light absorption factors resolved by positive matrix factorization model combined with light absorption spectra and abundant aromatic O-H and C=C functional groups determined by FTIR both indicate that aromatic compounds are important light-absorbing substances in WSOC, which also have a significant impact on fluorophores. Multiple linear regression analysis shows that the identified fluorophores by fluorescence spectra combined with parallel factor analysis contribute to about 62–93 % of the WSOC light absorption at all sites, in which humic-like substance (HULIS) contributes the most, especially highly‑oxygenated HULIS (29 %–50 %) with long emission wavelengths. Combustion source emissions and atmospheric chemical processes have significant impacts on the WSOC light absorption at some sites. Moreover, relative humidity (RH) can also affect MAE365 of WSOC with MAE365 values decreasing with the increase of RH when RH < 60 % and remaining relatively unchanged when RH > 60 %. Taken together, this study promotes a better understanding of the spatial heterogeneity of optical and structural properties of WSOC and their influencing factors in China.

Abstract. Chemical reanalysis products have been produced by integrating various satellite observational data to provide comprehensive information on atmospheric composition. Five global chemical reanalysis datasets were used to evaluate the relative impacts of assimilating satellite ozone and its precursor measurements on surface and free tropospheric ozone analyses for the year 2010. Observing system experiments (OSEs) using the multiple reanalysis systems in similar settings were conducted to examine the impacts of differences in reanalysis systems on observing system assessments. Without data assimilation, large discrepancies remained among the control runs owing to model biases. Data assimilation improved the consistency among the systems, reducing the standard deviation by 72−88 % in the lower troposphere through the lower stratosphere, while improving agreement with independent ozonesonde observations. The OSEs suggested the importance of precursor measurements, especially from tropospheric NO2 columns, for improving ozone analysis in the lower troposphere, with varying influences among the systems (+0.1 % in GEOS-Chem and +7 % in TCR-2, with only NO2 assimilation). Adjustments made by direct ozone assimilation showed similar vertical patterns between the TCR-2 and IASI-r systems, with increases of 6−22 % and decreases of 2−21 % in the middle and upper troposphere, respectively, reflecting the biases of the forecast models. These results suggest the importance of considering the effects of the forecast model performance and data assimilation configurations when assessing the observing system impacts to provide unbiased evaluations of satellite systems and to guide the design of future observing systems.
MPeat2D – a fully coupled mechanical–ecohydrological model of peatland development in two dimensions
Authors: Mahdiyasa Adilan W. , Large David J. , Icardi Matteo , Muljadi Bagus P.
Published: August 2024

Abstract. Higher-dimensional models of peatland development are required to analyse the influence of spatial heterogeneity and complex feedback mechanisms on peatland behaviour. However, the current models exclude the mechanical process that leads to uncertainties in simulating the spatial variability in the water table position, vegetation composition, and peat physical properties. Here, we propose MPeat2D, a peatland development model in two dimensions, which considers mechanical, ecological, and hydrological processes together with the essential feedback from spatial interactions. MPeat2D employs poroelasticity theory that couples fluid flow and solid deformation to model the influence of peat volume changes on peatland ecology and hydrology. To validate the poroelasticity formulation, the comparisons between numerical and analytical solutions of Mandel's problems for two-dimensional test cases are conducted. The application of MPeat2D is illustrated by simulating peatland growth over 5000 years above a flat and impermeable substrate with free-draining boundaries at the edges, using constant and variable climate. In both climatic scenarios, MPeat2D produces lateral variability in the water table depth, which results in the variation in the vegetation composition. Furthermore, the drop in the water table at the margin increases the compaction effect, leading to a higher value of bulk density and a lower value of active porosity and hydraulic conductivity. These spatial variations obtained from MPeat2D are consistent with the field observations, suggesting plausible outputs from the proposed model. By comparing the results of MPeat2D to a one-dimensional model and a two-dimensional model without the mechanical process, we argue that mechanical–ecohydrological feedbacks are important for analysing spatial heterogeneity, shape, carbon accumulation, and resilience of peatlands.
An increase in the spatial extent of European floods over the last 70 years

Published: August 2024

Abstract. Floods regularly cause substantial damage worldwide. Changing flood characteristics, e.g., due to climate change, pose challenges to flood risk management. The spatial extent of floods is an important indicator of potential impacts, as consequences of widespread floods are particularly difficult to mitigate. The highly uneven station distribution in space and time, however, limits the ability to quantify flood characteristics and, in particular, changes in flood extents over large regions. Here, we use observation-driven routed runoff simulations over the last 70 years in Europe from a state-of-the-art hydrological model (the mesoscale Hydrologic Model – mHM) to identify large spatiotemporally connected flood events. Our identified spatiotemporal flood events compare well against an independent flood impact database. We find that flood extents increase by 11.3 % on average across Europe. This increase occurs over most of Europe, except for parts of eastern and southwestern Europe. Over northern Europe, the increase in flood extent is mainly driven by the overall increase in flood magnitude caused by increasing precipitation and snowmelt. In contrast, the increasing trend in flood extent over central Europe can be attributed to an increase in the spatial extent of heavy precipitation. Overall, our study illustrates the opportunities to combine long-term consistent regional runoff simulations with a spatiotemporal flood detection algorithm to identify large-scale trends in key flood characteristics and their drivers. The detected change in flood extent should be considered in risk assessments as it may challenge flood control and water resource management.

Os resíduos sólidos domésticos, quando destinados e/ou dispostos inadequadamente, causam problemas à saúde ambiental e humana, em especial, em áreas ribeirinhas, onde não tem, no mínimo, coleta pública de resíduos sólidos. Diante disso, o presente estudo objetivou analisar a gestão dos resíduos sólidos domésticos no Projeto de Assentamento Agroextrativista (PAE) Ilha Itaúna, município de Cametá-PA. Foi aplicado um questionário estruturado a 200 moradores das comunidades dessa ilha, de forma aleatória. Os dados obtidos foram tabulados e analisados descritivamente. Vidros, metais, lixo eletrônico (e-lixo) e sementes de açaí são descartados indevidamente no ambiente, enquanto plásticos são queimados. Em sua maioria, os entrevistados não sabiam da existência de metais pesados resultantes do e-lixo, evidenciando a carência de informação nesse PAE sobre resíduos tóxicos. Grande parte dos informantes já teve algumas doenças ou cortes acidentais causados por metais descartados indevidamente. A incineração dos resíduos ocorre às proximidades das residências, o que, na maioria dos casos, causa incômodo para os vizinhos, além de contribuir para o aparecimento de algumas enfermidades. Com base nisso, os moradores entrevistados no PAE Ilha Itaúna convivem com a problemática dos resíduos sólidos domésticos em relação à destinação final inadequada desses materiais, sendo eles os próprios causadores, além de ser resultado da omissão do poder público ligada à falta de ações educativas para a consciência ambiental e ausência de alternativas para descarte e reaproveitamento de resíduos pós-consumo.

Objective: We sought to classify dermatologic conditions presenting in rural inpatient hospitalization. Methods: Retrospective chart review. Conclusion: Limited rural dermatology care in the United States prompted the establishment of an inpatient dermatology consult line in rural Upstate New York. Over 3 years, 27.7% of consults were admitted for dermatologic concerns, 21.5% for both dermatologic and medical issues and, 50% for non-dermatologic reasons but later seen by dermatologists. Common conditions included eczematous rashes, infections, drug reactions, edematous skin conditions, and autoimmune diseases. Among patients admitted for dermatologic concerns, cellulitis (3) and rashes (3) were the most common. Interestingly, 74% of provisional dermatologic diagnoses matched final diagnoses before further workups. Approximately 58.5% of consults were deemed highly valuable. Followup showed 73.8% improvement, 23.1% deceased from different pathologies, and 3.1% stable. Understanding the rural dermatology landscape could enhance access, diagnostic accuracy, and the feasibility of inpatient consult services. Understanding the rural dermatology landscape may improve access to specialist care, increase diagnostic accuracy, reduce disease burden and associated costs, and communicate the feasibility of inpatient consult services either in-house or via teledermatology to rural hospital systems.

Investigating Microbial Dynamics and Bacterial Vaginosis Susceptibility in Women who have Sex with Women
Authors:   State University of New York, Upstate Medical University, Syracuse, NY, USA., Vinagolu-Baur Julia
Published: August 2024

Bacterial Vaginosis (BV) remains a prevalent gynecologic health concern, with emerging research indicating a potential association between women who have sex with women (WSW) and an increased susceptibility to BV infections. Recent studies have explored the microbial dynamics within the vaginal microbiota of WSW, revealing distinct patterns that may contribute to a higher incidence of BV in this population. The etiological factors underlying this susceptibility include disruptions in the balance of Lactobacillus species, crucial for maintaining vaginal health. However, the existing literature presents a complex interplay of socio-behavioral and biological factors influencing BV risk among WSW, necessitating further investigation. Future research should strive to gain a more comprehensive understanding of the specific mechanisms influencing microbial communities in the context of same-sex sexual activity among women, exploring potential preventive strategies and tailored interventions to mitigate BV risks in this population. Our review highlights the need for a refined and multidisciplinary approach to address the intricacies of BV susceptibility in women engaging in same-sex relationships.

In memory of the distinguished logician, philosopher and political activist V.A. Yankov (1935 - 2024)
Authors: Yankov Kirill , Citkin Alex , Vandoulakis Ioannis , Denisova Tatiana
Published: August 2024

This session consists of four short presentations:

**A brief overview of the biography of V.A. Yankov** (Kirill Yankov)

**Yankov’s contributions to propositional logic** (Alex Citkin)

The talk I will present two most significant contributions by V.A. Yankov: the Yankov Logic and Yankov characteristic formulas.

**V.A. Yankov’s Contribution to the History and Philosophy of Mathematics** (Ioannis Vandoulakis)

The talk will present three significant contributions of V.A. Yankov to the History and Philosophy of Mathematics:
1) By inviting A.A. Markov, the founder of the Russian school of constructivism and his teacher, to respond to Heyting’s fictional persons “Class,” “Form,” “Int,” “Pragm,” and “Sign,” which represent classical mathematics, formalism, intuitionism, pragmatism and significism, respectively, when he edited the Russian translation of Heyting’s Intuitionism. This response is the only historical record of Markov’s views on Brouwer’s intuitionistic mathematics and logic.
2) His appraisal of A.S. Esenin-Vol’pin’s program of ultra-intuitionistic foundations of mathematics stated in his commentary published in a volume dedicated to Esenin-Vol’pin by Finn and Daniel’ in 1999, in which he also included three less known and hardly accessible works of Esenin-Vol’pin [1967, 1971, 1999] devoted to the theory of modalities, deontic logic, the theory of disputes and the logic of trust.
3) His novel interpretation of the rise of mathematics and mathematical proof in ancient Greece. It is formulated by considering the development of the early Greek philosophers’ ontological conceptions.

**V.A. Yankov’s existential research program** (Tatiana Denisova)

In this talk, I will discuss the least known and, at the same time, the most controversial research program proposed by V.A. Yankov, namely his philosophical conception of the existential history of human thought, which is based on the idea of reconsidering the WHOLE history of human thought from an existential perspective. That means that the whole history of philosophy, regardless of the immediate subject of philosophers’ reasoning, is required to be reinterpreted as a history of “existential types”, i.e., as a history of the changes in the human’s self-understanding and the correlated changes in human’s understanding of the general picture of the world.

Los programas de imagen generativa se conceptualizan a la luz de la teoría del aparato estético y la teoría de la visión poshumana. Las imágenes se analizan según la teoría de los imaginarios sociales, culturales y simbólicos. El análisis revela los sesgos ideológicos y tendencias estéticas en los imaginarios simbólicos y regímenes retóricos que se sintetizan visualmente sobre la frontera México-Estados Unidos a través de programas de producción de imágenes generativas; y construye una perspectiva sociopolítica crítica sobre tres aspectos principales: una conceptualización de los programas de imagen generativa como aparatos tecnoestéticos; una reflexión sobre los procesos creativos de construcción de discursos visuales producidos por dispositivos de inteligencia artificial; y un análisis de los sesgos ideológicos y estéticos de las imágenes, entendidas como objetos tecnoestéticos obtenidos a partir de esta tecnología de producción visual.
"Ecologia" e condições físicas da reprodução social
Authors: Chesnais François , Serfati Claude
Published: August 2024

A ideia central apresentada neste artigo é a seguinte: hoje em dia, por trás de palavras como "ecologia" e "meio ambiente", ou ainda nas expressões "questões ecológicas" e "questões ambientais", encontra-se nada menos do que a perenidade das condições de reprodução social de certas classes, de certos povos e, até mesmo, de certos países.
Sobre a ilusória origem da mais-valia
Authors: Carcanholo Reinaldo A.
Published: August 2024

A teoria do valor-trabalho de Marx tem sido submetida a intensa e sistemática crítica, desde praticamente seu surgimento, há mais de um século. Todo o esforço dirigido a mostrar seus supostos equívocos ou inconsistências, sem dúvida nenhuma, tem uma elevada motivação ideológica.
Lukács e a atualidade do marxismo
Authors: Toledo Caio Navarro de
Published: August 2024

Em Lukács e a atualidade do marxismo, estudiosos dos trabalhos do pensador húngaro escreveram textos que apresentam afinidades interpretativas e confluem na medida em que estão voltados à discussão da questão das origens, do significado e da relevância filosófica e política das obras que abordam a problemática da Ontologia.
Esboço para o estudo do ponto de vista da mercadoria na literatura brasileira
Authors: Roncari Luiz
Published: August 2024

Este ensaio é apenas um esboço, composto por linhas ainda um tanto forçadas, sobre um tema que poderia se constituir numa espécie de espinha dorsal para uma história interpretativa da literatura brasileira e que o autor considera que valeria a pena ser melhor pesquisado e desenvolvido.
A marca
Authors: Engels Friedrich
Published: August 2024

A marca deve ser entendida como uma associação de aldeias que reunia camponeses (mas não exclusivamente4) detentores de parcelas de terra na qual a forma de apropriação não pode ser descrita de modo simples e conciso como na expressão propriedade plena ou, nem mesmo, na expressão propriedade comunal. O termo marca (originalmente, sinal, fronteira ou território circundado por uma fronteira) e o termo companheiros da marca eram aplicados, respectivamente, às terras baldias e à associação que as possuía, em regime de propriedade ou de usufruto. Os camponeses que faziam parte das associações aldeãs e vicinais tinham direito ao usufruto das terras baldias; por vezes eram mesmo proprietários delas. Dadas as características da economia rural da época era de capital importância o usufruto dos bosques e dos terrenos de pastagem.
Neoliberalismo e lutas sociais no Brasil
Authors: Graciolli Edilson José
Published: August 2024

Esse número da Revista Idéias é um dossiê sobre a relação entre o neoliberalismo e os principais movimentos sociais e partidos de esquerda no Brasil. Resultado de uma pesquisa ainda em curso no Cemarx/Unicamp, o trabalho já revela uma qualidade e um fôlego fundamentais ao esforço de análise sobre a abrangência e os efeitos do neoliberalismo.
Um intelectual marxista indignado e generoso
Authors: Ruy José Carlos
Published: August 2024

O momento em que o autor de um livro clássico deixa de viver enseja a lembrança do autor e também um certo balanço da importância de sua obra e da contribuição dela ao progresso do conhecimento. O historiador marxista Clóvis Moura fechou os olhos no dia 23 de dezembro de 2003 em plena atividade - ele acabara, nas semanas anteriores, de conferir as provas daquela que considerava sua obra mais importante, resultado de três décadas de pesquisa, o Dicionário da escravidão.
Fórum Social Mundial - A história de uma intervenção política
Authors: Loureiro Isabel
Published: August 2024

Desde o primeiro Fórum Social mundial, reunido no final de janeiro de 2001 em Porto Alegre, ao último, em Mumbai, na Índia, a grande imprensa paulista fez desse evento uma cobertura tão grotesca que requer explicação. Embora o espetáculo de desinformação esteja em parte ligado ao preconceito no tocante a tudo que fuja ao figurino neoliberal, creio que o mais decisivo é a profunda insensibilidade em relação a um fenômeno político novo que exige repensar seriamente antigas categorias.
Os exuberantes anos 90

O autor do livro, que foi professor na Universidade de Stanford e, agora, leciona na Universidade de Columbia, EUA, ganhou em 2001 o Prêmio Nobel de Economia.

1964
Authors: Toledo Caio N. de
Published: August 2024

Por ocasião do 40° Aniversário do movimento político-militar que derrubou o governo constitucional de João Goulart (1961-1964), a maioria das universidades públicas e algumas faculdades privadas, entidades culturais, órgãos públicos, sindicatos de trabalhadores e os meios de comunicação promoveram palestras, seminários, mesas-redondas, entrevistas, depoimentos, exposições iconográficas sobre este crucial momento da recente história política brasileira; novos livros e algumas reedições sobre esse período também foram publicados.
A hegemonia e o paradoxo do público e do privado. Contribuição à crítica do conceito habermasiano do espaço público
Authors: Demirovic Alex
Published: August 2024

Em geral, o público e o privado foram entendidos, de maneira essencialista, como duas áreas separadas da sociedade moderna. Há boas razões para isso. Em primeiro lugar, há a separação entre o lugar de moradia e o lugar de trabalho, que Weber considerou uma das características centrais do processo ocidental de racionalização.
A corrente subterrânea do materialismo do encontro (1982)
Authors: Althusser Louis
Published: August 2024

Chove.Que este livro seja, então, de início, um livro sobre a simples chuva. Malebranchec se interrogava: “Por que chove sobre o mar, as grandes estradas e a areia?”, dado que esta água do céu que ao longe molha as culturas (e isto é ótimo) não acrescenta nada à água do mar ou se perde nas estradas e nas praias. Não se tratará aqui de esta chuva ser providencial ou contraprovidencial. Este livro se ocupa, ao contrário, de outra chuva, de um tema profundo que percorre toda a história da filosofia e que foi combatido e recusado tão logo foi enunciado: a “chuva” (Lucrécio) de átomos de Epicuro que caem paralelamente no vazio, a “chuva” do paralelismo de atributos infinitos de Espinosa e de outros autores ainda como Maquiavel, Hobbes, Rousseau, Marx, Heidegger e Derrida.
A arte entre o trabalho e o valor
Authors: Martins Luiz Renato
Published: August 2024

Constituirá a história da arte um domínio de raridades, preciosismos e virtuosismos ou uma investigação sobre modos históricos de produção de valor, e portanto à sua maneira também uma economia e uma reflexão sobre o trabalho humano? O historiador Giulio Carlo Argan, logo no início de História da Arte, um texto eminentemente teórico em que revê criticamente as principais correntes da historiografia da arte, estabelece uma distinção que opera como um divisor de águas no domínio geral da investigação da arte. Considerando que as obras de arte participam modernamente do processo geral de circulação e pertencem ao conjunto de coisas que têm valor, Argan propõe uma distinção quanto ao modo de se lidar com a arte: pode-se cuidar do valor, por exemplo, identificando-o, classificando-o, qualificando-o etc. Ou se pode inquirir sobre o valor, perguntar por sua condição, sua fisiologia, como se constitui historicamente etc.
Celso Furtado
Authors: Sampaio Jr. Plinio de Arruda
Published: August 2024

No final de 2004, o Brasil perdeu um de seus mais lúcidos críticos: o economista Celso Furtado. Trabalhador incansável, suas brilhantes sínteses sobre a problemática do subdesenvolvimento pautaram praticamente todos os debates da segunda metade do século XX sobre os dilemas da formação econômica. Concorde-se ou não com suas teses, é impossível entender o Brasil moderno sem dialogar com suas criativas interpretações teóricas e históricas.
Revolução chinesa, antimperialismo e a luta pelo socialismo hoje
Authors: Losurdo Domenico
Published: August 2024

João Quartim de Moraes: Na resenha que consagrou em O Globo (“Prosa & Verso”, 1.1.05) a seu livro Fuga da História? – A Revolução Russa e a Revolução Chinesa vistas de hoje, Leandro Konder pondera que “a motivação estrita e estreitamente econômica não combina com os ideais dos socialistas, com a luta incessante que eles travam contra as desigualdades, contra a opressão, contra as injustiças, e em favor de um aumento da participação das camadas populares na vida política”.
Zero à esquerda
Authors: Loureiro Isabel
Published: August 2024

Zero à esquerda (que poderia ter por subtítulo “o mundo de marcha a ré”), coletânea de artigos e entrevistas de Paulo Arantes publicados de 1997 a 2003, é um livro que vem na hora certa, precisamente porque colabora na tarefa urgente de repensar a esquerda no Brasil. Em vez de ficar com as “coisas boas de sempre”, a integridade intelectual do autor o obriga a partir das “coisas novas e ruins”, bem no espírito da coleção anteriormente coordenada por ele e Iná Camargo Costa na Editora Vozes.
Marxismo e Ciências Humanas
Authors: Lima Marcelo Guimarães
Published: August 2024

Marxismo e Ciências Humanas reúne trabalhos apresentados no “Segundo Colóquio Marx e Engels”, organizado em novembro de 2001 pelo Centro de Estudos Marxistas (Cemarx) do IFCH, Unicamp. Como se observa na apresentação da obra, a definição das ciências humanas é um primeiro campo de embates. Daí partirem os editores de, por um lado, um critério prático-acadêmico: identificando as ciências humanas tal como aparecem no panorama institucional universitário atual, e, por outro lado, assinalando uma unidade mínima no campo marxista: a concepção do socialismo como necessidade ou possibilidade histórica.
A burguesia no governo Lula
Authors: Boito Jr. Armando
Published: August 2024

Este artigo examina as relações de diferentes frações da burguesia com o governo Lula. Defende a tese de que este governo, sem romper com a hegemonia do grande capital financeiro, melhorou a posição da grande burguesia interna industrial e agrária no interior do bloco no poder. Argumenta ainda que essa modificação secundária não incorpora os interesses do campo operário e popular.
