River debris is the main problem from the negative impact of poor waste management. The composition of river debris in Jakarta consists mostly of plastic waste. Plastic waste from river debris has an opportunity for energy recovery. This study aimed to see the potential for utilizing river debris in energy recovery in power plants. This research was conducted at three sampling shelter points in Pesing, Pluit, and Perintis. Waste generation and composition were quantified using the load count method on Indonesian state standards for seven consecutive days. River debris generation in Pesing, Pluitm, and Pernting averaged 7.2; 3; and 1.8 tons/day. More than 60% (w/w) of plastic bag waste was found in the Pesing and Pluit shelters, while 67.3% was found in the Perintis shelter. Based on the calorific value of each plastic waste, the energy potential from plastic waste recovery can reach 16,197,109 kWh/year. This is equivalent to an electricity supply of 0.05% of the total electricity demand in Jakarta.

Authors: Santos Andressa Gomes dos , Pereira Ana Carolina Costa
Published: September 2022

Pesquisas com foco em história da matemática, especialmente voltadas para a Inglaterra do século XVII, destacam as questões políticas e a fagulha inicial da revolução industrial. Nesse entorno, há outros aspectos que fizeram parte, como a valorização dos estudos sobre matemática prática. Nesse viés, o artigo objetiva conhecer o Gresham College e sua relação com a matemática prática do seculo XVII em Londres. Dessa maneira, são explorados as perspectivas as quais necessitaram que houvessem um estudo árduo sobre a matemática prática no século XVII, o trânsito de conhecimento na cidade londrina e a relação do Gresham College nesse cenário de ascenção das práticas no território inglês. Percebe-se que esse College teve influência em duas frentes em relação as matemáticas, uma voltada para o ensino e outra associada as relações sociais e intectuais de estudiosos europeus do período.
Uma história das fluxões às derivadas na obra de Colin MacLaurin
Authors: Mendes Iran Abreu , Soares Evanildo Costa
Published: September 2022

Em uma publicação de 1742, intitulada A Treatise of Fluxions (Um Tratado das Fluxões), Colin MacLaurin argumenta sobre o conceito de fluxão, medida pelo acréscimo ou decréscimo gerado em um determinado momento por meio do movimento considerado continuamente uniforme a partir das relações entre espaço e tempo. Neste artigo discorremos sobre um cenário do desenvolvimento histórico-epistemológico do conceito de derivada a partir das noções de fluxões presentes em produções matemáticas de Colin Maclaurin influenciadas pelo trabalho de Isaac Newton, visando traçar um mapa dos princípios que norteiam o conceito de derivada e suas regras de derivações, contextualizadas nas relações entre velocidade, espaço e tempo.
Desventajas educativas, sociales y tecnológicas en tiempos de pandemia: La interseccionalidad en las estudiantes de una unidad UPN en la Ciudad de México
Authors: González Callejas José Luis , Mejía Pérez Gustavo
Published: September 2022

El objetivo de este escrito es mostrar, a partir de los resultados de un cuestionario aplicado durante mayo de 2020, las condiciones en que las alumnas de una unidad de la Universidad Pedagógica Nacional (UPN) en la Ciudad de México han continuado sus estudios durante la pandemia Covid-19. El concepto de interseccionalidad nos permite mostrar que las desventajas sociales y económicas (precariedad laboral, trabajo no remunerado, dependencia económica) en las que vivían las estudiantes antes de la pandemia se recrudecieron, en particular para aquellas que trabajan en el sector educativo, pues a las tareas que ya realizaban se sumaron el trabajo desde casa y el cuidado de las personas dentro del hogar (triple jornada laboral). Ante esta situación se sugiere desarrollar estrategias enfocadas en las mujeres del sector educativo (en particular en aquellas que aún están en formación), para que la pandemia y el eventual regreso a las aulas, no redunde en sobrecarga de trabajo y empeoramiento de sus condiciones laborales.
Justicia afectiva: micropolítica y construcción de una habitabilidad escolar
Authors: Cruz Vadillo Rodolfo
Published: September 2022

Este trabajo tiene como propósito proponer una idea de justicia afectiva como condición para hacer habitable la escuela. Se parte del supuesto que en el mismo momento que los estudiantes pasan por las aulas de las instituciones escolares, se dan forzosamente procesos de subjetivación, elementos micropolíticos que han posibilitado la apuesta por lo considerado valioso frente a lo que no lo es y, al hacerlo, han distribuido de forma desigual las relaciones de afectividad, reconociendo el éxito de algunos frente al fracaso de muchos otros. Una justicia afectiva refiere la habitabilidad hospitalaria del espacio escolar, la separación de la lógica del rendimiento de las diversas formas de ser y estar en el mundo, donde cabe el desacuerdo, el conflicto y la diferencia radical. Construir una micropolítica escolar capaz de hacer esta distinción, favorecerá la afectividad de los estudiantes y, con ello, la oportunidad de sentirse bien recibidos en el espacio escolar.
¿ Quién está detrás de la pantalla? Análisis crítico de experiencias educativas en pandemia
Authors: Garduño Teliz Elvia , Salgado Ramírez Alma , Morales Bautista María Luisa
Published: September 2022

Desde el marco de la pandemia, se desea revelar ¿quién está detrás de la pantalla? El objetivo es analizar desde la empatía las experiencias personales relacionadas con el rol educativo de docentes y estudiantes. A partir de las expresiones del componente afectivo, cognitivo y social de la empatía integradora, se intervino con un grupo de diez docentes y 47 estudiantes, en el proyecto educativo virtual “Café Tecnopedagógico” que abrió espacios para la expresión y el diálogo. Con una metodología cualitativa e interpretativa de comparación constante se encontraron diferencias sobre la empatía entre las personas que están detrás de las pantallas vinculadas al rol educativo que desempeñan. Desde la docencia, la empatía se enmarca en compromiso con el ethos profesional, la apertura al cambio, la resignificación de los aprendizajes para la vida y el reconocimiento del estudiante como persona. Desde el estudiantado, se enmarca en la relación con sus pares al valorar nuevas experiencias y aprendizajes en un proceso paulatino y continuo de adaptación que demanda recibir empatía de los docentes, pero sin reciprocidad hacia ellos. En ambos actores se revela la necesidad de pasar a la acción empática como parte de los procesos formativos en la nueva normalidad educativa.

En particular se estudia si se modificaron los modelos de admisión a EMS como respuesta a la emergencia; así como cuáles fueron las estrategias instrumentadas para apoyar la transición a la EMS a nivel estatal. La investigación se realizó a partir de análisis documental de la admisión a EMS en las 32 entidades federativas. Los resultados muestran que cinco entidades modificaron el modelo general de admisión como respuesta a la emergencia. También que la estrategia más utilizada fue la reprogramación o aplazamiento de exámenes de admisión y el uso de plataformas informáticas de apoyo (diez entidades respectivamente). Otras estrategias, aunque menos utilizadas, fueron la cancelación de costos de admisión (una entidad) y la suspensión de exámenes de selección (una entidad).
Dealing with COVID-19 stressful events, stress and anxiety: the mediating role of emotion regulation strategies in Italian women
Authors: Di Maggio Ilaria , Romola Michela , Lacava Elisabetta , Maressa Raffaella , Bruno Francesco
Published: September 2022

Background

This study aims to better understand the causal relationship between COVID-19 stressful events, perceived stress, emotion regulation strategies and anxiety symptoms in Italian women. Specifically, we assumed that: (i) different COVID-19 stressful events can directly or indirectly influence the manifestation of anxiety symptoms; (ii) perceived stress and emotion regulation strategies, can mediate the relationship between COVID-19 stressful events and anxiety symptoms.

Participants and procedure

An online survey was distributed during the Italian mandatory lockdown - between 18th and 28th April 2020 - across the national territory. The final sample was composed by 1132 women living in different Italian regions (North 63.3%, Centre 14.2%, South 18.5%, Islands 4%) with a mean age of 40.19 years, ranging from 19 to 83 years (SD = 12.87). Partecipants filled out the Perceived Stress Scale (PSS-10), Spielberger State-Trait Anxiety Inventory (STAI) X1/R, Emotion Regulation Questionnaire (ERQ-10), five dichotomous questions assessing the COVID-19 stressfull events and a demographic form. Pearson correlation analyses were performed to examine whether associations between factors conformed to the prerequisites for path analysis. Path analysis was conducted to test the model.

Results

“Having contracted the flu during the COVID-19 pandemic” and “Having a family member infected by COVID-19” have a direct effect on the level of perceived stress and an indirect effect on the manifestation of anxiety symptoms. Finally, we found that emotion regulation strategies mediate the relationship between perceived stress and state anxiety symptoms.

Conclusions

Our results allow to select the Stressful Events to which, in pandemics era, it is necessary to place a particular attention in a clinical setting and suggest the implementation of psychological interventions that place Emotion Regulation as an essential direct target of treatment in chronic stress-related pathology such as anxiety disorders.
Socially based inequities in breast cancer care: intersections of the social determinants of health and the cancer care continuum
Authors: Sayani Ambreen
Published: September 2022

Rapid advances in the field of medical imaging, drug development and genomics have paved the way for revolutions in the way breast cancer in treated and managed, such that the five-year survival for breast cancer in Canada averages 88%. Despite advances in treatment and overall survival, vast disparities by material advantage or disadvantage occur across the entire breast cancer care continuum. As a result, individuals lower down the socioeconomic ladder are more likely to have cancer diagnosed at a later stage, and have less availability to basic resources such as nutritious food and prescription drug coverage. In Canada, increasing austerity measures have resulted in higher levels of income inequality, deepening poverty, homelessness and growing precarious working conditions. The purpose of this paper is to describe the ramifications of spending cuts, and social structural inequality on the cancer care trajectory. By using the example of breast cancer care, this paper serves to advance the discussion of what it means to consider the intersections of power, resources and opportunities in creating gendered social inequality, and the implications of such â€˜structures of constraint  for women experiencing cancer. Through this illustration we are able to conceptualise that the foundations of health equity are built upon social equity, and one cannot be achieved without the other.
Decolonizing Health Care: Reconciliation Roles and Responsibilities for White Settlers
Authors: McGibbon Elizabeth
Published: September 2022

The purpose of this paper is to enhance a nascent discussion to white settlers about how they can be active participants in reconciliation action to decolonize health careâ€”by way of truths. I start with an examination of settler denial and settler truth-telling about Indigenous genocide, along with the deadliness of white settler health care racism, which results in embodied oppressionâ€”oppression that is the root of Indigenous inequities in the social determinants of health (SDH). White settler privilege is emphasized, including persistent impacts of Western, Eurocentric, and biomedical knowledge dominance in health care, and related suppression of Indigenous knowledge systems and healing traditions. I analyze how white settlers can engage in performing decolonization with critical perspectives on the SDH, allyship, and anti-racist, anti-oppressive health care. Although persistent white settler acts of racism, including systemic racism in health, legal, and educational systems, make reconciliation seem an impossible goal, we continue to be ethically bound to walk alongside Indigenous peoples in the Truth and Reconciliationâ€™s Commissionâ€™s Calls to Action.
Fair workplaces, better jobs: Is Ontario addressing precarious employment?
Authors: Chang Kiki
Published: September 2022

The purpose of this paper is to examine how Bill 148, introduced by the province of Ontario in 2017, addresses the issue of precarious employment.  Bill 148 was created based on information from The Changing Workplaces Review, which reported on Ontario's labour standards and employment systems.  An overview of precarious employment in Ontario is provided, including a working definition of the term, statistics, rates, and demographics.  The issues that face precarious workers are explored, using the framework of the four dimensions of precarious work as identified by Rodgers (1989) and Vosko (2010).  The Changing Workplaces Review and Bill 148 are analyzed to see if they fully address the concerns of precarious workers in Ontario.  The paper concludes with suggestions on how the government of Ontario can continue to address work and employment conditions of those who are precariously employed.

Published: September 2022

O Nordeste se destaca como a região que mais gera energia eólica no Brasil, uma vez que a soma dos quatro estados mais relevantes (Rio Grande do Norte, Bahia, Ceará e Piauí) representava, em novembro de 2021, 81,2 % da geração total nacional (19,7 GW), conforme dados da Agência Nacional de Energia Elétrica (ANEEL). Este artigo tem por objetivo analisar os critérios que devem ser considerados durante a escolha da localização dos parques eólicos, considerando a existência de comunidades tradicionais. Foram selecionadas duas comunidades tradicionais para exemplificar as problemáticas: Cumbe (município de Aracati/CE) e Xavier (município de Camocim/CE). O percurso metodológico trilhado partiu de uma análise quali-quantitativa, desenvolvida em três etapas: consulta à literatura científica, construção de banco de dados geográficos e produção de mapeamento investigativo. Os resultados apontaram 94 parques de energia eólica onshore e 5 projetos de energia eólica offshore, que coadunam com 58 unidades de conservação e 464 assentamentos rurais do Instituto Nacional de Colonização e Reforma Agrária (INCRA). Concluiu-se que os critérios de localização desses empreendimentos devem atender à legislação e às expectativas de participação social, fazendo-se necessário considerar o uso de metodologias participativas, como uma ferramenta de obtenção de informações relevantes no processo de implantação, a fim de reduzir danos e conflitos socioambientais.

Adults that resided within a metropolitan area hospitalized with Covid-19 at a community hospital between January 2020 and November 2020 were included in the study. Data including patient’s age, sex, length of stay, and co-morbid conditions were extracted from the hospital electronic health record. The patients were classified according to severity of disease based on a Covid Severity Index (qCSI) score, using patient’s vitals upon admission. Patient locations were classified per EPA mapping for lead exposure from water pipes.

RESULTS

The qCSI score was significantly higher in the high exposure group, with a mean of 4.6 (SD = 4.4), than the low exposure group, which had a mean of 2.1 (SD = 3.2) (p = 0.004). The median risk stratification levels differed significantly (p = 0.006). Length of stay was also significantly greater in the high exposure group, mean 11.4 (SD 10.7), then in the low exposure group, mean 6.2 (SD = 7.2) (p = 0.01).

CONCLUSION

This study demonstrated an association between Covid-19 severity and patients that have had high lead level exposure. Further research is needed to explore this possible association, such as studies involving larger datasets.

Abstract. Quantification and control of NOx and CO2 emissions are important across the world to limit adverse climate change. We present a new top-down method, an improved superposition column model to estimate day-to-day NOx and CO2 emissions from the large city of Wuhan, China, located in a polluted background. The lasted released version 2.3.1 TROPOMI NO2 columns and the version 10r of the OCO-2 observed CO2 mixing ratio are employed. Our estimated NOx and CO2 emissions from Wuhan are verified against bottom-up inventories with small deviations (< 3 %). Based on the estimated CO2 emissions, we also predicted daily CO2 column mixing ratio enhancements, which match well with OCO-2 observations (< 5 % bias, within ±0.3 ppm). We capture the day-to-day variation of NOx and CO2 emissions from Wuhan in 2019–2020, which does not reveal a substantial ‘weekend reduction’ but does show a clear ‘holiday reduction’ in the NOx and CO2 emissions. Our method also quantifies the abrupt decrease and slow rebound of NOx and CO2 emissions due to the Wuhan lockdown in early 2020. This work demonstrates the improved superposition model to be a promising new tool for the quantification of city NOx and CO2 emissions, allowing policy makers to gain real-time information into spatial-temporal emission patterns and the effectiveness of carbon and nitrogen regulation in urban environments.
Toward targeted observations of the meteorological initial state for improving the PM2.5 forecast of a heavy haze event that occurred in the Beijing–Tianjin–Hebei region

Abstract. An advanced approach of conditional non-linear optimal perturbation
(CNOP) was adopted to identify the sensitive area for targeted observations
of meteorological fields associated with PM2.5 concentration forecasts
of a heavy haze event that occurred in the Beijing–Tianjin–Hebei (BTH)
region, China, from 30 November to 4 December 2017. The results show that a
few specific regions in the southern and northwestern directions close to
the BTH region represent the sensitive areas. Numerically, when
predetermined artificial observing arrays (i.e. possible “targeted
observations”) in the sensitive areas were assimilated, the forecast errors
of PM2.5 during the accumulation and dissipation processes were
aggressively reduced; specifically, these assimilations, compared with
those in other areas that have been thought of as being important for the
PM2.5 forecasts in the BTH region in previous studies, exhibited a more
obvious decrease in the forecast errors of PM2.5. Physically, the
reason why these possible targeted observations can significantly
improve the forecasting skill of PM2.5 was interpreted by comparing
relevant meteorological fields before and after assimilation. Therefore, we
conclude that preferentially deploying additional observations in the
sensitive areas identified by the CNOP approach can greatly improve the
forecasting skill of PM2.5, which provides, beyond all doubt,
theoretical guidance for practical field observations of meteorological
fields associated with PM2.5 forecasts.

Abstract. Arctic warming and sea level change will lead to widespread permafrost thaw and subsequent mobilization. Sedimentary records of past warming events during the last glacial–interglacial transition can be used to study the conditions under which permafrost mobilization occurs. Long-chain n-alkyl lipids and lignin phenols are two types of biomarkers excellently suited for the reconstruction of terrestrial higher plant vegetation, as they are derived from epicuticular waxes and from the major rigidifying material of higher plants. For the Okhotsk and Bering Seas off the mouths of the Amur and Yukon rivers, respectively, published records reported the temporal variations of n-alkyl lipid accumulation recording mostly erosive processes. Surface runoff, vegetation type, and degree of organic matter degradation as reflected by lignin have not been investigated so far. Here, we present new lignin phenol records from marine sediment cores and compare them with previously published lipid biomarker data from these two subarctic marginal seas. We find that in the Yukon Basin, vegetation change and wetland expansion began already in the early deglaciation (ED, 14.6–19 ka BP). This timing is different from observed changes in the Okhotsk Sea reflecting input from the Amur Basin, where wetland expansion and vegetation change occurred later in the Preboreal (PB). In the two basins, angiosperms contribution and wetland extent all reached maxima during the PB, both decreasing and stabilizing after the PB. We also find that the permafrost of the Amur Basin began to become remobilized in the PB. Retreat of sea-ice coupled with increased sea-surface temperatures in the Bering Sea during the ED might have promoted early permafrost mobilization. In both records, accumulation rates of lignin phenols and lipids are similar, suggesting that under conditions of rapid sea-level rise and shelf flooding, both types of terrestrial biomarkers are delivered by the same transport pathway.

Abstract. Brown carbon (BrC) constitutes a large fraction of organic carbon and exhibits strong light absorption properties, thus affecting the global radiation budget. In this study, we investigated the light absorption properties, chemical functional bonds, and sources of BrC in six megacities in China, namely Beijing, Harbin, Xi’an, Chengdu, Guangzhou, and Wuhan. The average values of the BrC light absorption coefficient and the mass absorption efficiency at 365 nm in northern cities were higher than those in southern cities by 2.5 and 1.8 times, respectively, demonstrating the occurrence of abundance of BrC in northern China’s megacities. Fourier transform–infrared (FT-IR) spectra revealed sharp and intense peaks at 1640, 1458–1385, and 1090–1030 cm−1, which were ascribed to aromatic phenols, confirming the contribution of primary emission sources (e.g., biomass burning and coal combustion) to BrC. In addition, we noted peaks at 860, 1280–1260, and 1640 cm−1, which were attributed to organonitrate and oxygenated phenolic groups, indicating that secondary BrC also existed in six megacities. Positive matrix factorization (PMF) coupled with multilayer perceptron (MLP) neural network analysis were used to apportion the sources of BrC light absorption. The results showed that primary emissions (e.g., biomass burning, tailpipe emissions, and coal combustion) made a major contribution to BrC in six megacities. However, secondary formation processes made a greater contribution to light absorption in the southern cities (17.9 %–21.2 %) than in the northern cities (2.1 %–10.2 %). These results can provide a basis for the more effective control of BrC to reduce its impacts on regional climates and human health.

Abstract. Sulfur dioxide (SO2) measurements from the Ozone Monitoring Instrument (OMI), Ozone Mapping and Profiler Suite (OMPS), and TROPOspheric Monitoring Instrument (TROPOMI) satellite spectrometers were used to update and extend the previously developed global catalogue of large SO2 emission sources. This version 2 of the global catalogue covers the period of 2005–2021 and includes a total of 759 continuously emitting point sources releasing from about 10 kt yr-1 to more than 4000 kt yr-1 of SO2 that have been identified and grouped by country and primary source origin: volcanoes (106 sources); power plants (477); smelters (74); and sources related to the oil and gas industry (102). There are several major improvements compared to the original catalogue: it combines emissions estimates from three satellite instruments instead of just OMI, uses a new version 2 of the OMI and OMPS SO2 dataset, and updated consistent site-specific air mass factors (AMF) are used to calculate SO2 vertical column densities (VCDs). The newest TROPOMI SO2 data processed with the Covariance-Based Retrieval Algorithm (COBRA), used in the catalogue, can detect sources with emissions as low as 8 kt yr-1 (in 2018–2021) compared to the 30 kt yr-1 limit for OMI. In general, there is an overall agreement within ±12 % in total emissions estimated from the three satellite instruments for large regions. For individual emission sources, the spread is larger: the annual emissions estimated from OMI and TROPOMI agree within ±13 % in 50 % of cases and within ±28 % in 90 % of cases. The version 2 catalogue emissions were calculated as a weighted average of emission estimates from the three satellite instruments using an inverse-variance weighting method. OMI, OMPS, and TROPOMI data contribute 7 %, 5 %, and 88 % to the average respectively for small (< 30 kt y-1) sources and 33 %, 20 %, and 47 % respectively for large (> 300 kt y-1) sources. The catalogue data show an approximate 50 % decline in global SO2 emissions between 2005 and 2021, although emissions were relatively stable during the last 3 years. The version 2 of the global catalogue has been posted at the NASA Global SO2 Monitoring web site (Fioletov et al., 2022).
