Dropouts Sample Clauses

Dropouts. 18.2.5.5.1.17.1 Dropouts are drops in the level of a signal of 12 dB or more for at least four (4) milliseconds. They are caused by protection switching events, radio fading, and conditions causing digital carrier systems to lose frame. Dropouts are critical for voiceband data performance but, if severe enough, will also affect voice quality.

Dropouts. Dropout rates due to rescue intervention in each of the VB-201 groups will be compared to the placebo group using ▇▇▇▇▇▇’▇ exact test.

Dropouts. The connection between alternative programs and dropout prevention, in its most positive sense, has been made intuitively since early in the alternative school movement.2 Many students originally served by the Free Schools were alienated from the traditional schools of the time (Deal, 1975). However, major research on effective programs for dropout prevention that linked to characteristics of alternative programs did not begin until the 1980s (Duttweiler, 1995; ▇▇▇▇▇▇▇▇ & ▇▇▇▇, 1997; ▇▇▇▇▇▇▇▇▇ et al., 1990; ▇▇▇▇▇▇▇, 1981; ▇▇▇▇▇▇ & ▇▇▇▇▇▇▇▇▇, 1987; ▇▇▇▇▇▇▇ et al., 1989). An understanding of, and interest in, the predictors and educational trajectory of dropouts has flourished throughout the past two decades. Initiatives such as Goal 23 of the National Education Goals (developed in 1990) illustrated the growing national interest in increasing the country’s graduation rate and understanding the problems of school dropouts (Office of Educational Research and Improvement [OERI], 1993). The OERI document called for research to identify educational practices and policies that might play a role in school dropout prevention. In particular, the document highlighted the need to understand more about school organizations and student-adult relationships that might bear on a student's decision to leave school. Formative work by the National Dropout Prevention Center (2001) and authors ▇▇▇▇▇▇▇ et al. (1989), ▇▇▇▇▇▇▇▇▇ et al. (1990) and others have helped identify patterns and perspectives on the dropout problem in our country. Most important, perhaps, is the understanding educators have gained about the complexity of dropout predictors and the diverse reasons for students dropping out. Recent education research examines these education issues through a multi-faceted lens, considering elements of home, school and community together to understand outcomes. ▇▇▇▇▇▇▇ et al. (1989) have explored the diverse characteristics of students who drop out and the many variables that may affect that decision: It is essential that educators realize that a wide range of students can become at risk of school failure, that students at risk of dropping out are not necessarily those with the least intellectual ability, and that standard labels for student characteristics do not capture the nature of the interaction between at-risk students and the school (p. 73). Alternatives are highlighted in the dropout literature because of the presence of several key characteristics commonly associated ...
