School Characteristics Related to High School Dropout Rates

Abstract: A B S T R A C T Dropping out of high school culminates a long-term process of disengagement from school and has profound social and economic consequences for students, their families, and their communities. Students who drop out of high school are more likely to be unemployed, to earn less than those who graduate, to be on public assistance, and to end up in prison. The present study examined dropout rates in Kentucky high schools (N = 196), using both quantitative and qualitative procedures. Pearson product-moment correlation coefficients were computed to identify those school-level variables that showed strong relationships to dropout rates. A sample of 20 schools with the highest dropout rates was compared to a sample of 20 schools with the lowest dropout rates using a multivariate analysis of variance. Furthermore, 4 schools from each group were selected as case examples. Information gathered from administrator surveys, staff interviews, and on-site observations provided detailed descriptions of the c...

A study of the routing and spectrum allocation in spectrum-sliced Elastic Optical Path networks

Abstract: In OFDM-based optical networks, multiple subcarriers can be allocated to accommodate various size of traffic demands. By using the multi-carrier modulation technique, subcarriers for the same node-pair can be overlapping in the spectrum domain. Compared to the traditional wavelength routed networks (WRNs), the OFDM-based Spectrum-sliced Elastic Optical Path (SLICE) network has higher spectrum efficiency due to its finer granularity and frequency-resource saving. In this work, for the first time, we comprehensively study the routing and spectrum allocation (RSA) problem in the SLICE network. After proving the NP-hardness of the static RSA problem, we formulate the RSA problem using the Integer Linear Programming (ILP) formulations to optimally minimize the maximum number of sub-carriers required on any fiber of a SLICE network. We then analyze the lower/upper bounds for the sub-carrier number in a network with general or specific topology. We also propose two efficient algorithms, namely, balanced load spectrum allocation (BLSA) algorithm and shortest path with maximum spectrum reuse (SPSR) algorithm to minimize the required sub-carrier number in a SLICE network. The results show that the proposed algorithms can match the analysis and approximate the optimal solutions using the ILP model.

Students' Perceptions of EAP Writing Instruction and Writing Needs Across the Disciplines

Abstract: As English for academic purposes (EAP) writing instructors and writing curriculum planners, we need to know the degree to which ESL writing courses have been successful in gauging and providing for ESL students' writing needs across the university curriculum However, making this determination is difficult because many academic writing requirements may be implicit in the curriculum of the disciplinary course and thus not amenable to ready description by the outsider Furthermore, we also need to know how much carryover from ESL writing courses occurs with ESL students—that is, what elements of their ESL writing instruction have they found useful and available to them as students in content courses? This article reports on a survey of former ESL students now in university-level content courses that is designed to investigate students' perceptions of the relationship between the writing instruction the students received in ESL writing classes and the actual writing tasks they found in courses across the disciplines The results of the survey include indications of which writing skills taught in ESL writing courses students found most useful in dealing with the writing demands of other content courses In their answers to open-ended survey questions, ESL students also described their perceptions of their ongoing writing needs beyond the ESL writing curriculum
