Inconsistent pseudorange biases in time links and their effect on BDS and GPS PPP frequency transfer
Authors: Song Wei , Zheng Fu , Tian Yuan , Zhang Dong , Shi Chuang
Published: December 2022

Precise point positioning (PPP) using global navigation satellite system (GNSS) phase and code measurements has recently been the primary technique for time and frequency comparisons. Several scholars have studied multi-GNSS PPP clock comparison, but the inconsistent pseudorange bias from receivers with different correlator spaces and front-end designs in pseudorange observations has not been considered. In this work, we analyze the characteristics of inconsistent pseudorange biases of the Global Positioning System (GPS), BeiDou Navigation Satellite System (BDS) and their effects on PPP frequency transfer. The biases are confirmed to exist in receivers from manufacturers Septentrio, Trimble and Leica and differ by manufacturers. To explicitly investigate the pseudorange biases effects of GPS and BDS on PPP time and frequency comparisons, nine stations with receivers from three different manufacturers that can track BDS-2 and BDS-3 signals are selected. Regarding PPP frequency transfer with inhomogeneous receivers, the modified Allan variances (MDEVs) of GPS and BDS PPP frequency stability are significantly optimized. According to the receiver-type classification strategy, the overall improvements of frequency transfer with Trimble-Septentrio and Trimble-Leica are 33%, 7% and 39% and 23%, 14% and 23% for GPS, BDS-2 and BDS-3, respectively. Moreover, the convergence time of clock comparisons is obviously shortened after using the bias corrections. For GOPE-BRUX and GOPE-MATE links, the corrected cases yield average clock difference stability gains of 38%, 35% and 53% and 35%, 35% and 23% for GPS, BDS-2, and BDS-3, respectively. The results show that the bias corrections are vital and allow more stable time links for PPP frequency transfer.

Published: December 2022

Despite their high nutritional and potential health benefits, cereals and pulses intake has not been increased in the last three decades. Several ready-to-eat (RTE) or ready-to-cook (RTC) formulations were implemented to overcome this and increase their consumption in bakery and snack products. In the present study, we selected five (5) different cereals and pulses, i.e., barley, finger millet, chickpeas, green gram, and horse gram, along with skimmed milk and unripe banana, and arrowroot powder, for the development of functional food formulations. The LC-HRMS/MS confirmed a total of 22 compounds with the MS/MS fragment ions for rutin, quercetin rhamnoside, quercetin-3-xyloside, chlorogenic acid, p-coumarylquinic acid, coumaric acid hexoside, epicatechin, ferulic acid, gallic acid, vanillic acid, protocatechuic acid, and trans-cinnamic acid respectively. A dose-dependent antioxidant potential against TAA, FRAP, DPPH, and ABTS radicals. Hence, the RTC formulations could merit balanced nutritional and nutraceutical needs of the growing malnourished population as sustainable, functional foods.

Published: December 2022

This study aims to investigate the relationship between parental bonding and parent-child relationships among the college-going adolescents. A scale suggested by Robert C. Pianta (1992) was used in this quantitative, cross-sectional study with a descriptive design. Among 1000 students of Chattogram Biggan College and Chattogram Commerce College in Chattogram, Bangladesh, 101 individuals were selected. The demographic profile of the participants; 46% of the respondents were male and 54% were female, all of them were aged between 17 to 19. In terms of feelings about spending time with parents, it was discovered that 62.4% of the total 101 participants are very satisfied with their mother, while 49% are very happy with their father. While 5.9% and 3% of participants are unhappy and very unhappy with their mothers, just 3.5% of the total participants are unhappy with their fathers. While a large proportion (almost 40%) have a strong bond with their mother. On the other hand, over three-quarters of respondents have disagreements with their fathers' proximity and dependence, according to the research. While a sizable proportion (about 30%) have a strong bond with their father. Whereas over 40% of respondents calculated overall intimacy with their father was low, and nearly 30% with their mother, the remaining respondents were either medium or highly intimate with their parents. Overall relationship intimacy with mothers and fathers was also found to be linked to various relationship characteristics such as conflict (P < 0.000), closeness (P < 0.000) and dependence (P < 0.000) according to the findings. Things that participants like (P-value = 0.047) and dislike (P-value = 0.040) most about mother, feelings when spending time with mother (P-value = 0.066), and things that dislike most about father (P-value = 0.058) had a marginally significant connection with gender.

Authors: Yao Qinghe , Jiang Zichao , Jiang Junyang , Ma Zhiwei
Published: December 2022

Aiming at the long-term and high-precision simulation of the magnetohydrodynamic (MHD) instabilities in the tokamak model, we developed a parallelized solver based on a fully implicit difference scheme. A 4th-order precision difference scheme and the Newton-Krylov method are employed in the proposed solver for both the flow and the electromagnetic field. To achieve high parallel efficiency, we adopt a strategy based on the spatial domain decomposition to partition the large Jacobian matrices in the iteration, and a buffer area based on the grid density is utilized to minimize the memory and time consumption. The accuracy of the methodology is verified, and the numerical results are validated by comparison with recognized results. The numerical results of the tearing mode instability in the tokamak model have demonstrated the precision and reliability of the algorithm, and the high parallel efficiency has been proven by the scalability test on the platform with up to 1280 threads, showing significant potential in the large-scale simulation of MHD problems.

Published: December 2022

Heterocyclic aromatic amines (HAA) are mutagenic compounds; however, their long-term effects on humans remain poorly studied. This study investigated the association between HAA concentration and mortality in adults. Data from the National Health and Nutrition Examination Survey 2013-2014 were linked to mortality data from 2019 and analyzed using Cox regression analysis to determine the association of different HAA with all-cause, cardiovascular disease (CVD), and cancer mortality. Age, sex, education level, race, poverty income ratio, body mass index, smoking status, drinking status, and serum cotinine were included as covariates in three different Cox regression models. This study included 1,713 adults with a median age of 47 years (49.5% men). During a median follow-up at 71 months, 100 deaths occurred. Owing to detection limits, only four had discernible detection rates and were included in our analysis. Among them, only norharman concentration was significantly associated with all-cause and CVD mortality. The hazard ratio (HR) was 1.50 (95% confidence interval: 1.10–2.04) for all-cause mortality when analyzing norharman concentration as a natural log-transformed continuous variable and 3.33 (95% confidence interval: 2.24–4.95) for CVD mortality. Associations remained consistent when norharman concentrations were analyzed as binary variables (split by median). Urinary harman concentration seemed to show a negative association with cancer mortality. No definitive evidence was found of an association between other HAA and mortality. Urinary norharman concentration is associated with all-cause mortality and CVD mortality in adults.

Published: December 2022

Cellulose has been developed as an alternative to petrochemical materials. By comparison with refined nanofiber (RCNF), lignocellulose nanofiber (LCNF) shows particular promise because it is produced from biomass using only mild pretreatment. The mechanical properties of LCNF depends on the contained lignin. However, the microscopic location of the lignin contained in LCNF has not been determined. Thus, we developed two methods to detect and visualize lignin. One uses a scanning transmission electron microscope (STEM) equipped with an energy dispersive X-ray spectroscopy (EDS) detector. The other method uses an atomic force microscope (AFM) equipped with a cantilever coated with an aromatic molecule. Both methods revealed that the lignin in LCNF covers a thin cellulose fiber and is precipitated in a grained structure. In particular, the AFM system was able to determine the nanoscopic location of lignin-rich areas. The present study establishes a strong tool for analyzing the characteristics of lignin-containing materials.

Published: December 2022

Background:
Pancreatic ductal adenocarcinoma (PDAC) is a highly aggressive malignancy with a poor survival rate, largely due to the lack of biomarker for early detection. Given the crucial roles of circulating and tumor-infiltrating myeloid cells in PDAC progression, the identification of specific subsets of them can be a biomarker in liquid biopsies for diagnosis and prediction of recurrence risk of PDAC.
Methods:
We analyzed PDAC tissue microarray by immunohistochemistry to measure cytokine expressions. Peripheral blood cells of PDAC patients were subjected to define distinct cell population of PDAC patients by single-cell RNA sequencing and flow cytometry. In addition, the presence of myeloid cells was analyzed by murine xenograft/orthotropic models of PDAC cell lines. Finally, we performed a clinical study to evaluate the correlation of IL-10R2 expression and PDAC diagnosis or recurrence.
Results:
We found enriched IL-10R2+/IL-22R1 + myeloid cells in peripheral blood from PDAC patients, and that they display a signature association with tumor-educated monocytes. In addition, we verified the positive correlation of pancreatic tumor growth with increased IL-10R2+/IL-22R1 + myeloid cells through the murine xenograft/orthotropic models. Most importantly, the IL-10R2 + myeloid cells signaled tumor recurrence 130 days faster than CA19-9 in post-pancreatectomy patients.
Conclusions:
Enriched IL-10R2 + myeloid cells in PDAC patient’s blood may benefit uncomplicated and effective diagnostic marker and indicator of recurrence.

Published: December 2022

The plant growth-promoting bacteria Herbaspirillum seropedicae is an endophytic diazotroph found in several economically important crops. Reliable, high-yield, and cost-effective methods are needed to determine bacterial viability in inoculant formulations or in plant. The present study aims to develop a PMA-qPCR assay to evaluate viable cells of H. seropedicae in pure culture and maize roots grown in vitro. H. seropedicae grown in a culture medium was submitted to heat treatment at 48°C for different periods of time. Maize roots were inoculated, grown in vitro and collected seven days after inoculation. The bacteria viable cells were quantified using qPCR, PMA-qPCR assays, and plate counting. Standard curves were prepared, and the efficiency obtained ranged from 85 to 99%. The limit of detection (LOD) was 101 genome copies, corresponding to 60.3 pg of DNA. Enumeration obtained in pure cultures by qPCR, PMA-qPCR and plate count were 8.85 ± 0.16, 6.51 ± 0.12 and 2.25 ± 0.30 log CFU.mL− 1 after heat treatment, respectively. These results showed that PMA-qPCR is a powerful approach for quantifying viable and viable but non-culturable cells in inoculants and plants. PMA-qPCR allowed reliable obtained results much faster than culture-dependent methods.

Cross Border Cooperation for Sustainable Environment Protection
Authors: ALBAYRAK T.
Published: December 2022

Oceans, seas, and coastal areas are indispensable component of the Earth‟s ecosystem and are critical to sustainable development. Protecting the delicate ecosystem of our oceans is vital for the future of the humanity under rapidly increasing use and industrialization of the oceans of the world. Increasing demands and pressures for the use of marine areas have forced managements to deal with problems in a comprehensive and covering multi users‟ approach. Joint education and research help to raise awareness on environmental challenges and also helps improving common expertise and capabilities in marine-related management, science, technology and engineering. Environmental protection is one of the key unifying problems for cross border cooperation. For example, the problem caused by invasive marine species (IMS) introduced via shipping is one of the largest problems and requires strong cooperation among governments and across sectors. IMS is transferred mainly through ships‟ ballast water and as fouling organisms. It is a large-scale problem which needs serious and urgent measures to be tackled with. Marine environment is not limited by country borders therefore it is fundamental to establish sustainable forms of cross-border cooperation. This paper intends to explain the novel approach of a strategic partnership project „‟BLUE4SEAS (B4S)‟‟on marine pollution and environment protection based on various joint research initiatives of project partners to set an example for cross- border cooperation for sustainable environment protection.

Authors: Zuo Yue , Zhang Bo , Yang Wei
Published: December 2022

In order to realize the accurate judgment of the ground fault and improve the fault discrimination effect, this paper proposes a low-current ground fault discrimination method for the primary and secondary fusion complete sets of equipment under the calculation of three-phase asymmetric harmonic power flow. The three-phase asymmetric harmonic power flow calculation is carried out, the ground fault line selection model is constructed according to the calculation results, and the faulted line is obtained by the zero-sequence active component method and the zero-sequence reactive power component method; the wavelet packet transform method is used to extract the transient zero-sequence power direction, and use it as a line selection criterion to identify whether a ground fault occurs. The amplitude characteristic enhancement value of each section is obtained by calculation. According to the distribution characteristics of the zero-sequence current amplitude of the faulted feeder, the corresponding section is selected as the fault section, and the mutation logic array is used in the determined fault section to realize the low-current grounding fault judgment. The experimental results show that the method has high judgment accuracy in practical application, and the highest value is 98.5 %, which indicates that the method can accurately judge the fault line and determine whether ground fault occurs.
ACE2 Receptor Polymorphism and its Correlation with Anti-SARS-CoV-2
IgM Antibodies - A Case-Control Study
Authors: Yahya Saira , Siraj Anum , Khan Amber , Awan Saleem
Published: December 2022

Background:

The SARS-CoV-2 pandemic originated in Wuhan, China in December 2019
and spread rapidly worldwide. The virus gets entry into target cells via angiotensin-converting enzyme
2 (ACE2) receptors and its gene is highly polymorphic.

Introduction:

The variations in SARS-CoV-2 susceptibility and severity can be explained on a genetic
level by studying the polymorphism in ACE2 receptor polymorphism.

Objective:

A prospective case-control study was designed to compare the ACE2 levels in SARS-CoV-
2 patients with the healthy controls in the local population, for which a total of 100 EDTA-containing
blood samples were included (50 SARS-CoV-2 IgM positive case and 50 healthy controls).

Methods:

PCR-RFLP was performed to investigate the polymorphism of ACE2 in genomic DNA and
the ACE2 plasma levels were determined through ELISA.

Results:

No significant difference in allelic and genotype frequencies (GG, GA, AA) were observed
while the ACE2 plasma levels were found to be decreased in positive samples.

Conclusion:

No significant association of the ACE2 gene polymorphism (G8790A) was found with
the SARS-CoV-2 susceptibility in the Pakistani population which intimates the search for other genetic
factors within the local population.

Authors: Regmi Manjari Rani , Bhattarai Mukul , Parajuli Priyanka , Botchway Albert , Tandan Nitin , Abdelkarim Jumana , Labedi Mohamed
Published: December 2022

Objectives:

This meta-analysis aims to investigate the recurrence of atrial fibrillation
(AF) post-ablation based on the various stages of fibrosis seen in the late gadolinium enhancement
magnetic resonance imaging (LGE-MRI).

Methods:

Electronic databases were searched using specific terms and identified nine studies that
met the inclusion criteria. A total of 1,787 patients underwent LGE-MRI to assess atrial fibrosis
before catheter ablation for AF. We performed three analyses: first, we compared stage IV versus
stage I (reference group). The second set examined the combined stages III and IV versus stages I
and II (reference group). The third set compared stage IV versus combined stages I, II, and III. The
metanalysis relied on a random-effects model to pool the odds ratios (OR) and 95% confidence intervals
(CI) using the DerSimonian and Laird method. The data was analyzed using StatsDirect
software in England.

Results:

The study showed a higher rate of AF recurrence after ablation in stage IV atrial fibrosis
than in stage I (OR, 9.54; 95% CI, 3.81 to 28.89; P<00001). Also, in patients with combined stages
III & IV of atrial fibrosis, AF recurrence was significantly higher after ablation than in stages I &
II groups (OR, 2.37; 95% CI, 1.61 to 3.50; P<00001). Similarly, compared to combined stages I,
II, and III, patients with stage IV have higher odds of recurrence post-ablation (OR, 4.24; 95% CI,
2.39- 7.52, P < 0.001).

Conclusion:

This metanalysis demonstrates the strong association between left atrial fibrosis in
LGE-MRI and AF post-ablation recurrence. The finding of this study will further assist clinicians
in predicting the recurrence rate of AF based on the amount of fibrosis and tailor therapeutic decisions
for further management.

Authors: Sanosi Abdulaziz B
Published: December 2022

The positive effect of Corrective Feedback (CF) on students’ writing performance has been a topic of dispute for a long time. The dominant belief around this issue is that students benefit from feedback to a certain extent. However, there is no consensus on what type of feedback can achieve that or the effect of CF provision on language learning in general. This study investigates the impact of Automated Written Corrective Feedback (AWCF), namely Grammarly AI-powered writing assistant, on students’ academic writing accuracy. After being allotted to control and experimental groups, sixty-four university students participated in the study. The participants underwent a pre-test to validate their homogeneity and levels and a post-test to explore the effect of using Grammarly on the written work of the experimental group. The main finding of the research is that after 14 weeks of using Grammarly, the experimental group members showed a significant improvement in their written accuracy compared to the control members. Moreover, it was found that the progress was represented in a substantial drop in the number of errors pertaining to specific categories while errors of other types remained unaffected. The implications of the findings are discussed, and suggestions for further research are presented.

Published: December 2022

The principle of the presumption of innocence is one of the principles regulated in the Criminal Procedure Code (KUHAP). The application of the principle of the presumption of innocence is closely related to the application of rights to individuals, for example to suspects in the crime of theft who are in the process of being investigated. The regulation of these rights is regulated concretely in the Criminal Procedure Code. However, despite this, the application of the principle of the presumption of innocence in this case the application of the rights of the suspect during the arrest and detention process is still not given much attention by police investigators. Therefore, the researcher raised two problem formulations. First, how is the application of every person arrested for committing the crime of theft to be considered innocent until there is an Inkracht Decision at the Pamekasan Police Resort. Second, how is the application of every person who is detained for the crime of theft must be considered innocent until the Inckracht Decision is made by the Pamekasan Resort Police. The research method used is a sociological juridical approach. It can be concluded that in the application of rights in the arrest process, two rights have not been implemented by the Pamekasan Police investigators, namely the suspect's right to ask the investigator to show an arrest warrant (Article 18 paragraph (1) KUHAP) and regarding the right for the family of the arrested suspect to receive a copy of the letter. an immediate arrest order (article 18 paragraph (3) KUHAP). While in the detention process, two rights have not been implemented, namely those related to the suspect's right to give information freely (article 52 KUHAP) and the suspect's right to obtain legal assistance and law enforcers are required to appoint legal counsel (article 54 KUHAP)

The Study of the Educational Program Competence Model Based on the Intellectual Analysis of the Labor Market Professional Requirements
Authors: Minaev D. V.
Published: December 2022

The educational standards of higher education — FGOS3++ require designing educational programs (EP) based on professional competencies in demand in the labor market. It is rec ommended to use professional standards. This way has certain disadvantages. For example, professional standards describe labor functions, but in the EP competencies are required. The use of professional standards in the development of the EP obviously determines a certain lag in the reaction in the labor market changes. An alternative to such EP design is a direct analysis of market requirements. Intelligent Analysis (IA) tools: data mining and machine learning can facilitate such analysis. An overview of developments in this direction is given. The results of the application of IA based on the KNIME analytical platform for determining the competence model of the EP in the feld of project management are presented. Automation aﬀected:the collection of requirements for more than 6000 vacancies of employers of the Head Hunter online resource; the analysis of texts presented in natural language (descriptions of EP of diﬀerent universities, professional standards and guidance materials of professional associations — SOVNET-Agile, IPMA OCB&ICB). Based on these data sets was carried out: tokenization, collocation of terms and topics, clustering of topics, the cross-classifcation of professional standards and guidance materials based on a pre-trained competence model of the EP. The results confrmed the efciency of the used technique. Such analytics allows us to dynamically systematize descriptions of professional activities and formulate considerations about the elements, structure, and mutual correspondence of the EP competence models and the competencies natural models on the labor market. In combination with the traditional expert assessment, it can contribute to the formation of a more complete isomorphism between the qualifcations of EP and professional activity.

Routes to Roots: Searching for the Streetlife of Memory
Authors: Dyen Doris J.
Published: December 2022

Routes to Roots: Searching for the Streetlife of Memory looks at the challenge of creating a driving guide whose aim is to enable visitors to discover and experience the folklife of a region previously unused by visitors, a region whose folklife, while vital and significant, is now often invisible even to residents’ eyes. The driving guide’s primary purpose was to encourage community revitalization through cultural tourism, but it evolved beyond that into a way of telling the region’s industrial story though its folklife sites, events, and activities. The author explores how members of the interdisciplinary project team influenced each other as the project progressed through the stages of conception, research, and design and how the resulting travel guide both fulfilled and reinterpreted the project’s original mission.

In einem Staat, dessen Hauptstadt von Berlin weniger weit entfernt ist als Rom. In einer Zeit, in der im Integrationsprozess – Stichwort Brexit und Populismus – ohnehin offensiv auf die Bremse getreten wird. Fest steht aber: Allein die Nationalstaaten werden die Herausforderungen der 2020er-Jahre nicht lösen können. Eine immer engere Zusammenarbeit der europäischen Staaten ist in Krisenzeiten wichtiger als je zuvor. Wie für Sicherheit sorgen, wenn auf europäischem Boden wieder Angriffskriege geführt werden? Wie die Partnerschaft mit den USA gestalten, wenn Amerikas starke populistische Strömungen deren Fundamente in Frage stellen? Wie mit den immer weiter anwachsenden Migrationsbewegungen umgehen?

Konsekvensene av mangelen på et rettsoppgjør – eller transitional justice – etter stalintidens uhyrlige overgrep preger Russland mer enn noensinne. Redaktørene av The Gulag in Writings of Aleksandr Solzhenitsyn and Varlam Shalamov henviser til dette manglende oppgjøret, og til den gradvise rehabiliteringen av Stalin i dagens Russland, som noen av motivasjonene for en fornyet forskningssatsning på Gulaglitteraturens to klassikere, Aleksandr Solzjenitsyn og Varlam Sjalamov.
The consequences of the dearth of efforts at transitional justice with regard to Stalin-era repressions affect Russia more than ever. The editors of The Gulag in Writings of Aleksandr Solzhenitsyn and Varlam Shalamov note this circumstance, and the gradual rehabilitation of Stalin in today’s Russia, as important reasons for renewed research efforts regarding the two classics authors of Gulag literature, Aleksandr Solzhenitsyn and Varlam Shalamov.

Ao propor as artes como experiência de verdade e a compreensão como modo de desvelamento de todo sentido, a hermenêutica filosófica fortalece a potência expressiva das obras de arte e impõe a interpretação no horizonte da linguagem como uma possibilidade concreta de investigação. É nesse sentido que o filósofo alemão Hans-Georg Gadamer (1900-2002) propôs a partir do livro Quem sou eu, quem és tu? uma interpretação hermenêutica dos poemas do romeno Paul Celan (1920-1970) para analisar as indeterminações entre as pessoas poéticas e o terreno discursivo da linguagem. A partir disso, este artigo propõe-se a experimentar o sentido de verdade na arte, elegendo a literatura e, em especial, o romance Água viva de Clarice Lispector (1920-1977), uma vez que este também lida com os temas da linguagem e diálogo. O resultado desta empreitada é uma análise profícua e não categórica sobre a manifestação da dialogicidade como processo fundante na constituição do “eu” e “tu” (poéticos).
Christopher Isherwood por meio de Paul Veyne
Authors: Da Silva Gustavo Ruiz
Published: December 2022

Este ensaio pretende tatear uma hipótese relacional entre dois elementos heterogêneos: a obra de Christopher Isherwood e o poema elegíaco. Para tal, tomar-se-ão duas obras de Isherwood – “Christopher and His Kind” (1976) e “The Berlin Stories” (1945) – e a peculiar interpretação de Paul Veyne acerca do modo de escrita elegíaca. O que se defenderá, então, é que ao se construir a personagem de Sally Bowles, Isherwood descola o ente extra-textual (Jean Ross), assim como faz consigo mesmo quando escreve sobre si. Como percurso para tal interpretação, este texto se divide em três partes: a primeira fará uma retomada biográfica de Christopher Isherwood, a segunda uma apresentação das duas personificações supracitadas, e a terceira uma explicação a partir do caráter elegíaco, tal como visto por Paul Veyne.
Um ator, cidadão das Luzes
Authors: Pires Helderson Mariani
Published: December 2022

Tendo como objeto de reflexão o ator no teatro francês das Luzes, este texto faz uma análise sobre as diferentes ideias de Denis Diderot e Jean-Jacques Rousseau a respeito do ofício do ator naquele contexto. De lá, busca extrair elementos que possam contribuir para a reflexão estética contemporânea sobre o ofício do ator e a sua formação pedagógica.
O objetivo desta reflexão é trazer presente um atributo de um tipo de ator proposto a partir das Luzes: cidadão. O ator cidadão resgata da ideia de democracia grega o conceito de cidadania, de extrema importância nas questões do século XVIII. O conceito de cidadão era o fator primordial para a realização de um novo modelo de Estado. E ainda mais, o ator, como cidadão, também conquistará na sociedade onde exerce seu ofício, um espaço político mais justo e igualitário.
Performance de um corpo ao avesso
Authors: Takaesu Emily Mayumi
Published: December 2022

O presente artigo pretende abordar a ideia de dispêndio ligada à experiência artística.  Investigaremos os fundamentos da violência, dos interditos e da transgressão com base nas proposições filosóficas de Georges Bataille. Nesse sentido, tomamos como referência artística a obra do artista austríaco Hermann Nitsch, que resgata elementos mitológicos e religiosos de celebração e afirmação profunda da existência pela via da sublimação do sofrimento. Tal sublimação se daria no enfrentamento da morte através do caráter simbólico dos dispositivos de seu “Teatro das Orgias e Mistérios” (Das Orgien Mysterien Theater). 

PALAVRAS-CHAVES: dispêndio; performance; morte; erotismo.

Mulheres que leem mulheres na sociedade de classes
Authors: Pimentel Cilento Bruna , Santos Garcia Cássia
Published: December 2022

Este trabalho relata a experiência do Clube de Leitura “Mulheres que Leem Mulheres” de Campinas/SP, com a leitura e discussão comparativa do livro “As relações sexuais e a luta de classes” de Alexandra Kollontai e de trechos do livro “A mulher na sociedade de classes: mito e realidade” de Heleieth Saffioti realizada em 30 de setembro de 2017. Durante os debates as participantes puderam notar os desdobramentos políticos e teóricos das questões de gênero trazidas pelas autoras e o imbricamento dessa temática com as demais contradições da ideologia dominante capitalista, sendo Saffioti fundamental a esta apreensão pelo rompimento teórico com a epistemologia patriarcal e a riqueza de informações e referências contida em sua obra.
Uma leitura de O poder do macho, de Heleieth Saffioti
Authors: Vilaça Mônica
Published: December 2022

A obra de Heleieth Saffioti é marcada por uma fecunda e abrangente produção, com contribuições que se articulam pela chave de análise patriarcado-capitalismo-racismo, assim como por uma preocupação em afirmar uma contribuição feminista, ou seja, orientada para a luta das mulheres. Neste texto, a partir de um diálogo com o livro O poder do macho, busco refletir sobre as contribuições trazidas por esta obra pensada como uma escrita para não iniciados, e o lugar ocupado por ela na maturação de minha apreensão de um caminho explicativo para a dominação e exploração das mulheres. Esta é a obra por meio da qual tomo contato com Saffioti. Suas preocupações e contribuições para uma interpretação da realidade brasileira que ao problematizar a presença das mulheres na teoria, propõe outras compreensões sobre o Brasil.
Nota introdutória sobre o conceito de práxis em Heleieth Saffioti
Authors: Grecco Fabiana Sanches
Published: December 2022

Nos últimos anos reacendeu-se o interesse pela Epistemologia Feminista, caracterizada por afirmar a indissociabilidade entre teoria e política, conformando-se, assim, como um tipo de práxis. Do mesmo modo, renovou-se a necessidade dos estudos de gênero refletirem sobre as maneiras como se interconectam diferentes relações sociais, como as de gênero, classe e raça. No diálogo entre esses dois eixos, ganha relevo o trabalho de Heleieth Saffioti acerca da práxis, o que justifica revisitar seu artigo “Violência de gênero: o lugar da práxis na construção da subjetividade”, publicado originalmente em 1997, no segundo número da revista Lutas Sociais.

Políticas do trabalho, precariedade e estágio. O caso italiano
Authors: Gjergji Iside
Published: December 2022

Nos últimos quarenta anos, a organização do trabalho e o mercado de trabalho nos países ocidentais passaram por inúmeras transformações radicais que levaram ao aumento da precariedade dos trabalhadores. Inúmeras reformas legislativas multiplicaram as tipologias dos contratos de curto prazo, reduzindo drasticamente a proteção jurídica dos trabalhadores. É nesse quadro que o legislador italiano introduziu importantes mudanças no setor de estágios. Ao analisar criticamente o conceito de precariedade dos trabalhadores – que ganhou aceitação renovada entre os cientistas sociais após a crise econômica mundial de 2007-2008 –, este artigo tem como objetivo examinar a evolução das políticas trabalhistas nas últimas décadas na Itália e a ligação entre a escalada da insegurança no emprego e a disseminação de estágios.
Precários e sobrantes: os sentidos do trabalho para usuários de drogas em situação de rua
Authors: Mendes Kíssila Teixeira , De Paiva Fernando Santana , Ronzani Telmo Mota
Published: December 2022

A população em situação de rua (PSR) apresenta-se hoje como expressão máxima da questão social. O objetivo deste artigo é analisar os sentidos do trabalho entre pessoas em situação de rua usuários de drogas. Foi realizada uma investigação etnográfica que se valeu de observação participante e entrevistas em profundidade realizadas com 6 homens em situação de rua, que vivem próximos de instituições que prestam serviços voltados para a PSR em Juiz de Fora (MG). Os resultados encontrados foram sintetizados a partir das seguintes categorias: a) o trabalho como valor central; b) o não reconhecimento de si como trabalhador; c) a reprodução do discurso precarizado. A partir desses resultados, refletimos como a centralidade da categoria trabalho e a inserção nele de forma precária têm impactos nocivos e específicos na saúde mental.

Published: December 2022

Nesta entrevista, a assistente social e psicanalista em formação Fernanda Almeida discorre sobre sua trajetória política e acadêmica, desde a atuação no Bairro da Brasilândia, periferia empobrecida de São Paulo, que, nestes tempos de coronavírus, se tornou um grande laboratório necropolítico. Trabalhadores/as negros/as e moradores/as das periferias precarizadas formam a grande maioria entre as vítimas fatais da Covid-19. Filha da classe trabalhadora, Fernanda aposta na ciência e na campanha de vacinação para todos/as e destaca o quanto o Sistema Único de Saúde é fundamental no combate à pandemia. É por meio da saúde pública, e não da saúde como mercadoria, que se poderá efetivamente salvar vidas. Para isso, é preciso defender a saúde pública e romper com a máquina ideológica de destruição do SUS.

A constituição dos sujeitos da ocupação periférica
Authors: Gonçalves Thiago Andrade , Nakano Anderson Kazuo , Miranda Antônio Marcos de
Published: December 2022

O objetivo deste texto é discutir o sujeito múltiplo, heterogêneo, coletivo e rizomático constituído em processos de subjetivação e em agenciamentos de lutas por um lugar de moradia. Nesse sentido, enfoca o sujeito da ocupação periférica visto como um tipo de “sujeito periférico”, conforme acepção de Tiaraju Pablo D’Andrea (2013). O sujeito da ocupação periférica é constituído a partir de processos de subjetivação vividos em agenciamentos territoriais realizados nas práticas de produção e apropriação de espaços urbanos periféricos da Região Metropolitana de São Paulo. Tais agenciamentos ocorrem, de um lado, nas ocupações de terras e imóveis ociosos empreendidas por diversos grupos que desejam um lugar de moradia e, de outro lado, na realização desse desejo com a conquista da moradia por meio da autogestão habitacional empreendida por militantes do Movimento dos Trabalhadores Sem Terra Leste 1.
