ALTERNATIVE EDUCATION: THE CRIMINALIZATION OF STUDENT BEHAVIOR
Public education was intended to give students a broad perspective to prepare them for living in a complex, diverse society. This article will examine a relatively recent development in public education: alternative education programs (AEPs). Using Texas public schools as a case study, this article argues that AEPs defeat public education’s goal of exposing students to a diverse student body. This is because AEPs segregate at-risk students-- usually Latinos, African Americans, Native Americans, and poor Whites--from the rest of the student population. This article deals with disciplinary AEPS, also known as DAEPs. Part I of the article will explore the legislative intent behind the Texas Education Code’s DAEP provisions. Part II will describe the Code’s DAEP provisions and how they have been supplemented by individual school district codes. Part III will describe how schools can boost their scores on accountability tests through the use of DAEPs. Part IV will discuss the author’s quantitative data on DAEPs, emphasizing the race, gender, and reading ability of students placed in DAEPs. Part V will give a qualitative description of a typical DAEP. The article will conclude by arguing that individual school districts have criminalized low student achievement by sending students with academic problems to DAEPs designed for student criminals
Ring graphs and complete intersection toric ideals
We study the family of graphs whose number of primitive cycles equals its
cycle rank. It is shown that this family is precisely the family of ring
graphs. Then we study the complete intersection property of toric ideals of
bipartite graphs and oriented graphs. An interesting application is that
complete intersection toric ideals of bipartite graphs correspond to ring
graphs and that these ideals are minimally generated by Groebner bases. We
prove that any graph can be oriented such that its toric ideal is a complete
intersection with a universal Groebner basis determined by the cycles. It turns
out that bipartite ring graphs are exactly the bipartite graphs that have
complete intersection toric ideals for any orientation.Comment: Discrete Math., to appea
Bistability for asymmetric discrete random walks
We show that asymmetric time-continuous discrete random walks can display
bistability for equal values of Jauslin's shifting parameters. The bistability
becomes more pronounced at increased asymmetry parameterComment: Follow-up note to hep-th/9411026[PRE 51, 5112 (May 95)], one fig.
