A wide variety of mobile applications aims to meet the daily needs of diverse people, such as transportation and commerce. Meanwhile, mobile accessibility is a worldwide concern. Accessibility is a requirement for any user to interact with software. For example, about 25% of the Brazilian population declares themselves as having some disability. Although traditional mobile software development approaches indicate that native development achieves higher computing performances, this implies high-priced development, difficult maintainability, and low accessibility for the interface components. Many mobile applications still lack accessibility, and people with disabilities may find barriers when interacting with them. We understand that Model-Driven Development (MDD) and cross-platform mobile development, together, may help to solve this gap and facilitate the development of more accessible mobile applications. Our goal is to create an MDD solution that generates accessible mobile applications. We place our focus on blind and low vision users to direct the development of our solution. In this work, we investigate MDD approaches for mobile development and appoint recommendations for accessibility in the user interface components. To achieve this goal, we developed AccessMDD, an approach to stimulate developers´ awareness of accessibility recommendations. This approach supports the inclusion of accessibility requirements and generates accessible user interfaces for mobile apps.

In particular, the domain of accessible cross-platform mobile apps has only received limited attention by research and practitioners. In this work, we set out to tackle mobile accessibility by identifying distinctive challenges, requirements, and solution techniques for mobile apps in contrast to established web development. Furthermore, a model-driven approach that integrates accessibility concerns into the development of cross-platform mobile apps is presented. To highlight the applicability of the proposed approach, parts of mobile prototypes accessible to visually impaired people were built based on the enhanced MD2 framework.

We show that the drop in the employment rate in post-outbreak months was largely driven by mass layoffs and not by workers quitting their jobs. Results from fixed-effects regression models show a strong fatherhood premium in the likelihood of being laid off for post-outbreak months compared to mothers, men without children, and women without children. We also found that the "fatherhood premium" was higher among lower-educated and mid-educated workers. These findings show that gaps in layoff rates exacerbated pre-existing forms of parental status and gender inequality in employment. Possible mechanisms are discussed, but more work is needed to explain why employers were less likely to lay off fathers following the outbreak, and the short-and long-term consequences of the COVID-19 pandemic in reinforcing parental status and gender inequality in employment in the United States.
