Abstract. SOCOL-AERv1 was developed as an aerosol–chemistry–climate model
to study the stratospheric sulfur cycle and its influence on climate and the ozone layer. It includes a sectional aerosol model that tracks the sulfate particle size distribution in 40 size bins, between 0.39 nm and 3.2 µm. Sheng et al. (2015) showed that SOCOL-AERv1 successfully matched observable quantities related to stratospheric aerosol. In the meantime, SOCOL-AER has undergone significant improvements and more observational datasets have become available. In producing SOCOL-AERv2 we have implemented several updates to the model: adding interactive deposition schemes, improving the sulfate mass and particle number conservation, and expanding the tropospheric chemistry scheme. We compare the two versions of the model with background stratospheric sulfate aerosol observations, stratospheric aerosol evolution after Pinatubo, and ground-based sulfur deposition networks. SOCOL-AERv2 shows similar levels of agreement as SOCOL-AERv1 with satellite-measured extinctions and in situ optical particle counter (OPC) balloon flights. The volcanically quiescent total stratospheric aerosol burden simulated in SOCOL-AERv2 has increased from 109 Gg of sulfur (S) to 160 Gg S, matching the newly available satellite estimate of 165 Gg S. However, SOCOL-AERv2 simulates too high cross-tropopause transport of tropospheric SO2 and/or sulfate aerosol, leading to an overestimation of lower stratospheric aerosol. Due to the current lack of upper tropospheric SO2 measurements and the neglect of organic aerosol in the model, the lower stratospheric bias of SOCOL-AERv2 was not further improved. Model performance under volcanically perturbed conditions has also undergone some changes, resulting in a slightly shorter volcanic aerosol lifetime after the Pinatubo eruption. With the improved deposition schemes of SOCOL-AERv2, simulated sulfur wet deposition fluxes are within a factor of 2 of measured deposition fluxes at 78 % of the measurement stations globally, an agreement which is on par with previous model intercomparison studies. Because of these improvements, SOCOL-AERv2 will be better suited to studying changes in atmospheric sulfur deposition due to variations in climate and emissions.

Abstract. Mapping the suitability of groundwater-dependent vegetation in semi-arid
Mediterranean areas is fundamental for the sustainable management of
groundwater resources and groundwater-dependent ecosystems (GDEs) under the
risks of climate change scenarios. For the present study the distribution of deep-rooted woody species in southern Portugal was modeled using climatic, hydrological and topographic environmental variables. To do so, Quercus suber, Quercus ilex and Pinus pinea were
used as proxy species to represent the groundwater-dependent vegetation (GDV). Model fitting was performed between the proxy species Kernel density and the selected environmental predictors using (1) a simple linear model and (2) a geographically weighted regression (GWR) to account for autocorrelation of the spatial data and residuals. When comparing the
results of both models, the GWR modeling results showed improved goodness
of fit as opposed to the simple linear model. Climatic indices were the main drivers of GDV density, followed by a much lower influence by
groundwater depth, drainage density and slope. Groundwater depth did not
appear to be as pertinent in the model as initially expected, accounting
only for about 7 % of the total variation compared to 88 % for climate
drivers. The relative proportion of model predictor coefficients was used as
weighting factors for multicriteria analysis to create a suitability map for the GDV in southern Portugal showing where the vegetation most likely relies on groundwater to cope with aridity. A validation of the resulting map was performed using independent data of the normalized difference water index (NDWI), a satellite-derived vegetation index. June, July and August of 2005 NDWI anomalies, for the years 1999–2009, were calculated to assess the response of active woody species in the region after an extreme drought. The results from the NDWI anomalies provided an overall good agreement with the suitability to host GDV. The model was considered to be reliable for predicting the distribution of the studied vegetation. The methodology developed to map GDVs will allow for the prediction of the evolution
of the distribution of GDV according to climate change and aid stakeholder
decision-making concerning priority areas of water resource management.
Climate Justice and Sustained Transnational Mobilization
Authors: Almeida Paul 
Published: September 2019

Samir Amin’s final essay called for the creation of a new international organization of progressive social forces. This essay provides evidence from twenty-first century transnational movements on the likelihood of the emergence of such an international organization and the issues and sectors most likely to facilitate coalitional unity. More specifically, the ecological crises identified by Amin in the form of global warming and climate change create an unprecedented global environmental threat capable of unifying diverse social strata across the planet. The climate justice movement has already established a global infrastructure and template to coordinate a new international organization to confront neoliberal forms of globalization. Pre-existing movement organizing around environmental racism, climate justice in the global South, and recent intersectional mobilizations serve as promising models essential to building an enduring international organization representing subaltern groups.
On Samir Amin’s Call for a Fifth International

Published: September 2019

In his prodigious output, from works on capitalist development to analyses of Islamist movements to involvement in the World Social Forum, Samir Amin’s was a consistent voice for struggle against capitalism’s domination of the world and its peoples. In this brief essay I address his call for a shift from movement to organization, indeed, toward a kind of Fifth International (Amin 2018a) and explain why I endorse it.

Fugitive Literati: Black Girls’ Writing as a Tool of Kinship and Power at the Howard School
Authors: Owens Tammy C. 
Published: September 2019

AbstractTeaching black children how to survive on their own was one of the primary goals of the Howard Orphanage and Industrial School (1868–1918) in New York. One skill, penmanship, proved to be particularly important for orphaned girls. “Fugitive Literati” examines an incident involving one of the institution’s former residents, a sixteen-year-old black girl domestic, who used her writing to resist being forced to marry a man who may have sexually assaulted her. Using black feminist thought to read the loud silences in the Howard Orphanage and Industrial School’s letters, I argue that the girl’s case shows how orphaned black girls used the “written word” to navigate power relations in the workplace and actively construct their desired kinship networks for survival. Further, I contend that the silences around the girl’s case in the archive tell of a strategy of dissemblance or the unique family-like veil of privacy within the institution.

Abstract: Adaptive development and executive functioning in children with diagnosis of conduct disorder and attention-deficit/hyperactivity disorder hyperactive/impulsive type. Adaptive development allows the subject emotional control, disposition towards new challenges and the expected socio-cognitive adjustment contextually, facilitating learning and executive and social functioning. The objective of the study was to determine executive-adaptive development in children with diagnostic criteria or conduct disorder (CD) or attention deficit hyperactive-impulsive type disorder (ADHD-I). With clinical instruments to identify diagnostic criteria for each nosology, 80 children were classified in control group (30), CD (34) or ADHD-I (16). Based on multinomial logistic regression, Kruskal Wallis, and χ2 tests, we found that an appropriate sleep, persistence in tasks, and academic achievement seem to act as protective factors for the clinical samples. Difficulties were observed in sequential planning, where the CD group presented better metacognitive control than ADHD-I. It was concluded that school environment provides factors to improve clinical symptomatology.Keywords: Adaptive factors; executive functions; attention deficit/hyperactivity disorder; conduct disorder; adaptive development.Resumen: El desarrollo adaptativo permite al sujeto el control emocional, la disposición hacia nuevos retos y el ajuste socio-cognitivo esperado contextualmente, facilitando el aprendizaje, funcionamiento ejecutivo y social. El objetivo del estudio fue determinar el desarrollo adaptativo-ejecutivo en niños con criterios diagnósticos para trastorno disocial (TD) o trastorno de déficit de atención/hiperactividad con predominio hiperactivo-impulsivo (TDAH-I). Con los instrumentos clínicos para identificar criterios diagnósticos de cada nosología, se seleccionaron 80 niños clasificados en el grupo de control (30), TD (34) o TDAH-I (16). Basándonos en pruebas de regresión logística multinomial, Kruskal Wallis, y χ2, encontramos que el sueño adecuado, la persistencia en las tareas y el logro académico parecían actuar como factores protectores para las muestras clínicas. Se observaron dificultades en planeación secuencial, donde el grupo TD presentó mejor control metacognitivo que el TDAH-I. Se concluyó que el ambiente escolar provee factores para mejorar la sintomatología clínica.Palabras clave: Factores adaptativos; funciones ejecutivas; trastorno de déficit de atención/hiperactividad; trastorno disocial; desarrollo adaptativo.

Abstract: Perceived social support and socio-demographic factors in relation to symptoms of anxiety, depression and stress in Chilean university students. Research with university students shows a high prevalence of mental disorders, so it is necessary to study the impact of protective variables such as social support. The objective of this study was to determine the influence of perceived social support and the socio-demographic factors gender and socio-economical level on symptomatology related to depression, anxiety, and stress. In the framework of a non-experimental and cross-sectional design, 449 undergraduate students answered the Depression, Anxiety and Stress Scales (DASS-21) and the Multidimensional Scale of Perceived Social Support (MSPSS). Results showed that perceived social support was negatively associated with psychopathological symptoms, and that family support is the strongest predictor of mental health symptomatology. These findings indicate that family social support is important to Chilean university students and plays a protective role against the symptoms of anxiety, depression and stress in this stage in life.Keywords: emerging adulthood; perceived social support; depression; anxiety; stress.Resumen: Las investigaciones con universitarios evidencian alta prevalencia de trastornos mentales por lo que es necesario estudiar el impacto de variables protectoras como el apoyo social.

En el marco de un diseño no experimental y transversal, 449 estudiantes universitarios respondieron las Escalas de Depresión, Ansiedad y Estrés (DASS-21) y la Escala Multidimensional de Apoyo Social Percibido (MSPSS). Los resultados mostraron que el apoyo social percibido se asocia de forma inversa a los síntomas psicopatológicos y que el apoyo familiar es el mejor predictor ante la aparición de sintomatología de salud mental. Los resultados confirman que los jóvenes chilenos otorgan importancia al apoyo social familiar, el cual cumple un rol protector ante los síntomas de ansiedad, depresión y estrés en esta etapa vital.Palabras clave: Adultez emergente; apoyo social percibido; depresión; ansiedad; estrés.

Objective: Male infertility is a scourge of the 21st century. Its management remains a real headache. The objective of this study is to describe the general profile of male infertility at the IRIFIV In Vitro Fertilization Center, Casablanca, Morocco.
Materials and Methods: This is a retrospective and descriptive study of 295 patient files seen in consultation for conjugal infertility of the couple between 2017 and 2018. The parameters studied were clinical elements and paraclinical explorations.
Results: The average age of the patients was 37.5 years. The average duration of evolution of infertility was 5.5 years. Infertility was primary in 70.9% of cases and secondary in 29.1% of cases. Clinically, varicocele was the most common abnormality in 65.9% of patients. The seminogram was disrupted in 72% of cases. The main disturbances were oligozoospermia in 40.20% of cases and asthenozoospermia in 37% of cases.
Conclusion: The general profile of infertility is polymorphic. The causes of male infertility noted are multifactorial. Male infertility usually results in a quantitative and/or qualitative abnormality of the sperm. The improvement of the management of infertility must go through new ways of research including genetic and immunological for a good identification of usually hidden causes of infertility.

<p>This paper analyzes the connection between sustainability and financial performances of the six biggest banks in Brazil. Brazilian banks were analyzed regarding their socio-environmental and economic disclosure. We collected Socio-environmental data from annual reports, available on banks websites and financial data at Economática® database. Although disclosure data are not audited, which represents a limitation, these banks conduct their business in accordance with sustainable development policies and regulations, and publish information about initiatives. Spearman's non-parametric correlation provided a relationship assessment between variables for each bank. Results in this paper mostly showed a positive correlation between socio-environmental responsibility (SER) and financial performances, even considering the impacts of Brazilian crisis. The objective of this voluntary disclosure lays on companies’ legitimacy as a dialogue mechanism with society.</p><p> </p>

AbstractIt is desirable to design nonprecious metal nanocatalysts with high stability and catalytic performance for fine chemicals production. Here, a method is reported for the preparation of cobalt metal and cobalt oxide cores confined within nanoporous nitrogen‐doped hollow carbon capsules. Core–shell structured Zn/Co‐ZIF@polymer materials are fabricated through a facile coating polymer strategy on the surface of zeolitic imidazolate frameworks (ZIF). A series of hollow carbon capsules with cobalt metal and cobalt oxide are derived from a facile confined pyrolysis of Zn/Co‐ZIF@polymer. The hollow Co‐CoOx@N‐C capsules can prevent sintering and agglomeration of the cobalt nanoparticles and the nanoporous shell allows for efficient mass transport. The specific surface area and Co particle size are optimized through finely tuning the original Zn content in ZIF particles, thus enhancing overall catalytic activity. The yolk–shell structured Zn4Co1Ox@carbon hollow capsules are shown to be a highly active and selective catalyst (selectivity >99%) for hydrogenation of nitrobenzene to aniline. Furthermore, Zn4Co1Ox@carbon hollow particles show superior catalytic stability, and no deactivation after 8 cycles of reaction. The hollow Co‐CoOx@N‐C capsules may shed light on a green and sustainable catalytic process for fine chemicals production.

Published: September 2019

AbstractLithium (Li) metal is one of the most promising anode materials to construct next‐generation rechargeable batteries owing to its ultrahigh theoretical capacity and the lowest electrochemical potential. Unfortunately, practical application of Li metal batteries is severely hindered by short lifespan and safety concerns caused by Li dendrite growth during cycling. Herein, a coaxial‐interweaved hybrid Li metal anode is proposed for dendrite inhibition that significantly improves the cycling stability of Li metal batteries. The hybrid Li metal anode is fabricated by Li composition into a 3D interweaved scaffold, where each fiber of the interwoven scaffold is composed of a conductive skeleton and a coaxial lithiophilic layer modified on the surface. The coaxial‐interweaved structure endows the hybrid anode with favored Li affinity to guide uniform Li deposition, sufficient channels for ion transportation and electron conduction, and enhanced stability during Li plating and stripping. Consequently, the hybrid Li metal anode affords high Coulombic efficiency over 98.5% for 750 cycles with dendrite‐free morphologies in half cells and improved capacity retention of 80.1% after 100 cycles in LiFePO4 full cells. The innovative coaxial‐interweaved hybrid Li metal anode demonstrates multiscale design strategy from lithiophilic modification to scaffold construction and promises the prospect of Li metal batteries for future applications.
