AbstractBackground Ethiopia has made remarkable progress in expanding access to and provision of comprehensive abortion care. However, complications due to unsafe abortion still contributes to a significant proportion of maternal mortality in the country. As efforts to increase accessibility, availability, acceptability, and quality of comprehensive abortion care continue, evaluating service quality is critical. This study assesses the quality of comprehensive abortion care in public health facilities, from clients’ perspectives, in four regions of Ethiopia to examine how person-centered care differs based on facility and service characteristics. Methods We conducted 1,870 client exit surveys in 2018 using structured questionnaires with women who received induced abortion or postabortion care services from 76 public health facilities across four regions: Tigray, Amhara, Oromia, and Southern Nations, Nationalities, and People’s. We calculated descriptive, bivariate, and multivariable statistics to examine service characteristics associated with 30 person-centered care outcomes grouped into five domains. Results Comprehensive abortion care clients reported high levels of person-centered care, with participants reporting exceptionally positive experiences for outcomes in the dignity and respect domain and trust, privacy, and confidentiality domain. However, there was notable room for improving client experiences across three domains of person-centered abortion care: autonomy, communication and supportive care, and health facility environment. In the multivariate analysis, client-reported quality outcomes differed significantly by diagnosis, region, health facility type, and procedure type. Findings specifically reveal that clients in Amhara, at tertiary and primary hospitals, and who received postabortion care report lower person-centered care. Conclusions The positive experiences reported by comprehensive abortion care clients highlight the impact of the Ethiopian government’s strategy to increase abortion access in the public health sector. However, numerous disparities in person-centered care were identified, providing insight into opportunities to advance the quality of comprehensive abortion care. Recommendations include investment in initiatives to improve postabortion care client experiences, better integration of reproductive health services at higher-level facilities, and leveraging qualitative methods to research regional differences. These findings can direct regional-level and facility-based person-centered abortion care interventions to ensure the most effective impact on the health outcomes and human rights of people seeking comprehensive abortion care in Ethiopia.

Abstract
A global disaster, as the recent Covid-19 pandemic, affects every aspect of our lives and there is need to investigate these highly complex phenomena if one aims to diminish their impact in the health of population, as well as their socio-economic stability. In this paper we present an attempt to understand the role of the governmental authorities and the response of the rest of the population facing such emergencies. We present a mathematical model that takes into account the epidemiological features of the pandemic and also the actions of people responding to it, focusing only on three aspects of the system, namely, the fear of catching this serious disease, the impact on the economic activities and the compliance of the people to the mitigating measures adopted by the authorities. We apply the model to the specific case of Spain, since there are accurate data available about these three features. We focused on tourism as an example of the economic activity, since this sector of economy is one of the most likely to be affected by the restrictions imposed by the authorities, and because it represents an important part of the Spanish economy. The results of numerical calculations agree with the empirical data in such a way that we can acquire a better insight of the different processes at play in such a complex situation, and also in other different circumstances.

Abstract
Vinasse is one of the most polluting effluents in the sugar-alcohol industry due to its physicochemical properties. It poses a threat to soil fertility and can contaminate groundwater if not appropriately handled. Therefore, it is important to evaluate more sustainable and comprehensive vinasse treatment strategies to safeguard environmental integrity. So, this work aims to evaluate sugarcane bagasse and peanut shell, as renewable adsorbents, for the removal of organic matter, pH, and turbidity found in vinasse effluent. Commercial activated carbon was used to compare the performances. Experimental assays were conducted using the adsorbents under three different concentrations (1: 12.5 g L-1; 2: 25.0 g L-1; 3: 37.5 g L-1) at 3, 6, 12, 24, and 48 hours of treatment, under controlled temperature (25°C) and rotation (200 rpm). The bioadsorbents were able to promote marked removal of organic matter, showing natural adsorbent properties without any previous activation. Major COD removal (63.88%) was observed for the commercial activated carbon after 48 hours of treatment and a concentration of 37.5 g L-1. For the peanut shell and sugarcane bagasse, the major COD removal was 50.94% and 45.35%, respectively, after 48 hours of treatment and a concentration of 12.5 g L-1. The final effluent exhibited high residual COD content, indicating the necessity to associate with another treatment state, such as biodigestion or ozonolysis, acting as a pretreatment or as a posttreatment.

Abstract
Characterizing the interplay between exposures shaping the human exposome is vital for disease etiology. For example, cancer incidence is attributable to the independent and interactive multifactorial external exposures that shape health. Lung cancer is a perfect example of increased risk linked to environmental, socioeconomic, and lifestyle factors. However, radon epidemiological studies often fail to consider multiple exposures simultaneously. For example, moderating factors, such as PM2.5, may affect the transport of radon progeny to lung tissue.
This ecological analysis leveraged a population-level dataset from the National Cancer Institute’s Surveillance, Epidemiology, and End-Results data (2013-17) to simultaneously investigate the effect of multiple sources of low-dose radiation (gross activity and indoor radon) and PM2.5 on lung cancer rates in the United States. The county-level factors (environmental, sociodemographic, lifestyle) were controlled, and Poisson regression and random forest were used to assess associations with lung and bronchus cancer rates.
Tree-based ML method improved over traditional regression: Poisson regression: 7.58/7.39 (mean absolute percentage error, MAPE); Poisson random forest regression: 1.21/1.16 (MAPE). Effect of PM2.5 increased with the concentration of environmental radon, thereby confirming findings from previous studies that investigated the possible synergistic effect of radon and PM2.5 on health outcomes.
In summary, the results demonstrated (1) a need to include multiple environmental exposures when assessing radon exposure’s association with lung cancer risk, thereby highlighting exposomics framework and (2) that employing ML models may capture the complex interplay between environmental exposures and health, as in the case of environmental radiation exposure and lung cancer incidence.
Solar Geoengineering to Stop Annual Global Warming
Authors: Feinberg Alec 
Published: July 2023

Abstract
Solar geoengineering (SG) solutions have many advantages compared to the difficulty of carbon removal (CR): SG produces fast results, is shown here to have much higher efficiency than CR, is not related to fossil fuel legislation, and is something we all can participate in brightening the Earth with cool roofs, and roads. SG requirements detailed previously to mitigate global warming (GW) have been concerning primarily because of overwhelming goals and climate circulation issues. In this paper, higher feasibility is provided for solar geoengineering applications by focusing on physics-based estimates to stop annual increases in GW. Annual solar geoengineering (ASG) area modification requirements found here are generally 50 to possibly higher than 150 times less compared to the challenge of full SG GW mitigation.
Results indicate that AI paint drone technology is likely needed for Earth brightening to meet annual mitigation goals. As well, results indicate much higher feasibility for L1 space shading compared to prior literature estimates for full GW mitigation. However, stratosphere injections appear challenging in the annual approach.
A serious issue with implementing ASG is the problem of worldwide negative SG which currently dominates yearly practices with the application of dark asphalt roads and roofs. This issue is discussed.

Abstract

Human-induced actions aggravate forest degradation and result in carbon emissions. Increment of carbon emission raises land surface temperature (LST) and contributes to climate change. The aim of this study was to assess the impacts of forest cover change on carbon stocks, carbon emissions and LST over the period 1992–2022 using geospatial techniques in the Sor watershed, Western Ethiopia. The results revealed that forest land declined by 336.6 km2 due to the expansion of agricultural land with an area of 274.9 km2. Results show a decline in carbon stock of 58,883.4 tons/km2 while annual carbon emission exhibited an increasing trend of 2,418,083.91 tons to the atmosphere over the past three decades. As vegetation declined, LST increased by an average of 3.7 °C over the past three decades. All actors, including government and non-governmental organizations, should contribute to tree planting and reafforestation programmes to minimize the increasing trend of LST and carbon emissions. Furthermore, we need to build a climate-resilient green economy to protect people from the negative impacts of climate change.

Lithium cuprate (Li2CuO2) is being used for a wide range of applications due to its high lithium diffusion through the layer structure. Moreover, Li2+2xCu1-xO2-x non-stoichiometric material shows enhanced physicochemical properties. Therefore, lithium location understanding is highly important for lithium cuprate applications. This paper reports the structural coherence analysis, local and long atomic arrangement of Li2+2xCu1-xO2-x using X-ray diffraction (XRD), pair distribution function (PDF) and solid-state nuclear magnetic resonance (NMR) techniques. Li2CuO2, containing different excess quantities of lithium (from 0 to 60 at%), were synthesized by solid-state reaction. The synthesized ceramics presented nonstoichiometric structures, with Li2CuO2 type-structure. Two structural models were proposed to explain the high enhancement physicochemical properties of these ceramics; (i) the extra lithium atoms substitute copper sites, and (ii) lithium species occupy interstitial sites in the crystalline structure. Additionally, further thermal treatments rearrange the non-stoichiometric crystalline structures into the stable Li2CuO2 phase.

Gender Diversity and Audit Quality: Evidence from the Pairing of Audit Partners
Authors: Perry Yumin Zhang , Srinidhi Bin , Yang Zhifeng 
Published: July 2023

SUMMARY
Using the Chinese setting where two partners are assigned to lead each engagement, we find that gender-diverse partner pairs improve audit quality compared to same-gender partner pairs. We show that the positive effect of partner gender diversity is concentrated in the engagements led by two partners with similar seniority or collaborating as signatory partners for an engagement before or in clients with complex operations. We evaluate two potential factors that could drive the positive effect of partner gender diversity, namely, the perspective-broadening and the human capital factors, and show that perspective-broadening prevails, whereas the human capital factor does not. Our results are robust to controlling for endogeneity and using alternative measures of audit quality.
