Abstract
Purpose
The purpose of this paper is to highlight the opportunity for the energy policy in Brazil to tackle the very high cost-effectiveness potencial of solar energy to the power system. Three mechanisms to achieve ambitious reductions in the greenhouse gas emissions from the power sector by 2030 and 2040 are assessed wherein treated as solar targets under ambitious reductions in the greenhouse gas emissions from the power sector. Then, three mechanisms to achieve these selected solar targets are suggested.
Design/methodology/approach
This paper reviews current and future incentive mechanisms to promote solar energy. An integrated energy system optimization model shows the most cost-efficient deployment level. Incentive mechanisms can promote renewable sources, aiming to tackle climate change and ensuring energy security, while taking advantage of endogenous energy resources potential. Based on a literature review, as well as on the specific characteristics of the Brazilian power system, under restrictions for the expansion of hydroelectricity and ambitious limitation in the emissions of greenhouse gases from the power sector.
Findings
The potential unexploited of solar energy is huge but it needs the appropriate incentive mechanism to be deployed. These mechanisms would be more effective if they have a specific technological and temporal focus. The solar energy deployment in large scale is important to the mitigation of climate change.
Originality/value
The value of the research is twofold: estimations of the cost-effective potential of solar technologies, generated from an integrated optimization energy model, fully calibrated for the Brazilian power system, while tacking the increasing electricity demand, the expected reduction of greenhouse gas emissions and the need to increase the access to clean and affordable energy, up to 2040; proposals of three mechanisms to deploy centralized PV, distributed PV and solar thermal power, taking the best experiences in several countries and the recent Brazilian cases.

Abstract
This chapter provides an overview of how, from a multi-stakeholder approach, Brazil can recover, fight against climate change and build an inclusive and sustainable future for itself. The interdependencies of the climate change action and current COVID-19 pandemic are discussed through extensive secondary data research to provide an updated context on Brazilian initiatives or the lack thereof. Through a multi-stakeholder methodological approach, the response and recovery actions of Brazil's government are assessed and future scenarios are developed for the country.

Abstract
Purpose
The purpose of this paper is to explore the history of Black women as critical civic agents fighting for the recognition of their intersecting identities in multiple iterations of the feminist movement.
Design/methodology/approach
Utilizing Black feminism and intersectionality I explore the many ways in which Black women have fought against multiple forms of oppression in the first, second and fourth wave feminist movement and organizations in order to fight for their rights as Black women citizens.
Findings
Black women in the past and present have exhibited agency by working within such multiple civil rights movements to change the conditions and carve out inclusive spaces by working across differences and forging multiracial coalitions.
Originality/value
This paper serves as a call to action for social studies classroom teachers and teacher educators to rethink how we remember and teach feminist movements. I also explore how we can use this past to understand and advance the conversation in this present iteration of the women’s movement to work across differences in solidarity toward equal justice for all.

Abstract
Purpose
Few have studied the relationship between employment and health in the Medicaid population. The purpose of this study is to estimate the impact of job loss on the mental health of working Medicaid beneficiaries.
Design/methodology/approach
This study conducted a post hoc analysis of 1,538 adult Medicaid beneficiaries enrolled in a prospective cohort study. The authors matched participants who lost their job to participants who remained employed based on demographics, illness severity and social determinants of health. The authors estimated the effect of job loss on the odds of a diagnosis of depression and/or anxiety and self-reported mental health during a one-year follow-up period, stratified by prior history of depression and/or anxiety as documented in the Medicaid claims.
Findings
Among participants with no preexisting depression or anxiety, the incidence of depression or anxiety was 17% versus 7% (aOR = 2.85; 95% confidence interval (CI): 1.88 to 4.34) between those who lost versus kept their job, respectively, and the mean difference in self-reported mental health was −4.3 (95% CI: −6.02 to −2.58). Self-reported mental health was also poorer between those who lost versus kept their job among participants with preexisting depression and/or anxiety (x = −4.78 (95% CI: −8.90 to −0.66).
Research limitations/implications
Limitations of this study are as follows: we may not have matched on all factors that influence retaining a job; we do not distinguish between involuntary and voluntary job loss; generalizability is limited; and employment information is based on self-report.
Practical implications
Our society should invest more resources into supporting low-wage workers such as Medicaid beneficiaries.
Social implications
Active labor policies that connect people to jobs, help them retain their job and support skills training to secure a better quality job, could reduce health disparities in the Medicaid population.
Originality/value
Use of both claims and self-reported mental health information to evaluate the impact of job loss on working Medicaid beneficiaries.
