This is the publisher's version, also found here: http://cec.metapress.com/content/l5vq400577228810/?p=7708b4ddb79e4484ae1a1fc3d5bafcb6&pi=4This study examined the self-determination of adolescents with emotional disturbance (ED) and learning disabilities (LD)from the perspectives of special educators, parents, and the students themselves. Differences in self-determination ratings were associated with both disability group and respondent Specifically, adolescents with ED were found to have lower ratings of selfdetermination than students with LD, with the most pronounced differences evident from the teacher perspective. Eurthermore, students with ED identified infrequent opportunities at school and home for engaging in self-determined behavior, whereas educators and parents differed in their assessments of opportunities in each setting. Implications regarding increasing the self-determination skills and opportunities of adolescents with disabilities are discussed

The impact of COVID-19 on small business outcomes and expectations

To explore the impact of coronavirus disease 2019 (COVID-19) on small businesses, we conducted a survey of more than 5,800 small businesses between March 28 and April 4, 2020. Several themes emerged. First, mass layoffs and closures had already occurred—just a few weeks into the crisis. Second, the risk of closure was negatively associated with the expected length of the crisis. Moreover, businesses had widely varying beliefs about the likely duration of COVID-related disruptions. Third, many small businesses are financially fragile: The median business with more than $10,000 in monthly expenses had only about 2 wk of cash on hand at the time of the survey. Fourth, the majority of businesses planned to seek funding through the Coronavirus Aid, Relief, and Economic Security (CARES) Act. However, many anticipated problems with accessing the program, such as bureaucratic hassles and difficulties establishing eligibility. Using experimental variation, we also assess take-up rates and business resilience effects for loans relative to grants-based programs. © 2020 National Academy of Sciences. All rights reserved
