Training school psychologists to conduct culturally informed Functional Behavior Assessment interviews.

Exclusionary discipline is a racialized mechanism through which schools systematically remove racially and ethnically minoritized youth from the learning environment. Although the development of Functional Behavior Assessments (FBAs) and linked behavior support plans have been identified as an alternative practice, school psychologists often do not ask questions about the cultural and contextual factors that may influence students' behavior during FBA interviews. Therefore, training is warranted.

Exploring threats to internal validity of direct assessment in single-case design research.

Single-case design research studies have historically used external observers to collect time series data that may be used to evaluate intervention effectiveness; however, single-case interventions implemented in educational settings may use the person implementing the intervention (e.g., teacher) to collect data in order to maximize feasibility.

Value of brain magnetic resonance imaging in mitochondrial respiratory chain disorders.

Mitochondrial respiratory chain (MRC) disorders have variable clinical manifestations which are mainly neurologic. Diagnosis in children is more complex than in adults because the classic phenotype, ragged red fibers, and mtDNA mutations are rarely seen in children. Moreover, clinical manifestations of disease in developing brains are less explicit.

Pediatric mitochondrial respiratory chain disorders in the Centro region of Portugal.

The present study reviewed mitochondrial respiratory chain disorders diagnosed at the sole tertiary pediatric hospital in the Centro region of Portugal and estimated incidence and prevalence in this region. The Bernier criteria were used to retrospectively classify 200 children investigated from 1997 to 2006. A total of 78 patients were assigned with definite primary mitochondrial disorder, two thirds presenting in the first year of life.
