The 97 bilingual education program enhancement projects funded by the U.S. Department of Education's Office of Bilingual Education and Minority Languages Affairs in fiscal 1995 are analyzed for their demographic characteristics, goals and objectives, instructional characteristics, parent and family services, professional development, personnel training, and other program features. A subset of 33 programs was selected for in-depth analysis of features other than demographics. The 97 proposals, distributed among 21 states, served 53,535 students, 36,283 of whom were limited-English-proficient, from 78 language groups and at all grade levels. California received over half the funded projects. School districts were the main beneficiaries …

The Voltammetry Of Sc3@C82, Mark Anderson, Harry Dorn, Paul Burbank, Steven Stevenson, James Gibson
The Voltammetry Of Sc3@C82, Mark Anderson, Harry Dorn, Paul Burbank, Steven Stevenson, James Gibson
Mark R. Anderson
Many endohedral metallofullerenes have a C82 cage surrounding the metals, even though the normal arc-vaporization method of fullerene preparation does not generate C82 in significant abundance.1-10Manolopous et al.11-13attribute the low abundance of empty-cage C82 to the unfavorable electron configuration of this species. Consequently, the prevalence of C82 in metallofullerenes may be the result of an electron transfer from the encapsulated metal atoms to the fullerene cage.10-13 The extent of this charge transfer also contributes to the properties (e.g. catalytic, superconductive, nonlinear optical, and ferromagnetic) that are attributed to the endohedral metallofullerenes.14,15Because of the importance of the charge transfer reaction, characterization …
School-Industry Programs National Survey 1996, John Ainley, Marianne Fleming
School-Industry Programs National Survey 1996, John Ainley, Marianne Fleming
Dr John Ainley
In the present Australian context, school-industry programs are educational courses for Year 11 and/or Year 12 students that require students to spend time in the workplace as part of a structured experience that is recognised as part or their formal studies. This report is based on the second national survey of the extent and characteristics of those programs. It has as its principal aim the monitoring of the scale and characteristics of school-industry programs and is based on information from schools which enrolled students in Years 11 and 12 during 1996. The information encompasses the extent to which school-industry programs …
At-Risk Readers And Community Volunteers: A 3-Year Perspective, Catherine Rosemary, Marcia Invernizzi, Connie Juel, Herbert Richards
At-Risk Readers And Community Volunteers: A 3-Year Perspective, Catherine Rosemary, Marcia Invernizzi, Connie Juel, Herbert Richards

The Charlottesville Volunteer Tutorial, known locally as Book Buddies, is a one-to-one community volunteer tutorial that is an integral part of the Charlottesville City Schools' plan to ensure that all first- and second-grade children learn to read. Analyses of the first 3 cohorts reveal the growing efficacy of the program. Participants with greater than 40 sessions significantly outperformed participants with fewer than 40 sessions on most pre- and posttest gain scores and on both outcome measures of text reading and word recognition. Effect size for word recognition in Cohort III was +1.29, considerably higher than effect sizes reported for other …
Differential Expression Of Gap Junctions In Neurons And Astrocytes Dervied From P19 Embryonal Carcinoma Cells, Daniel Belliveau, J. Bechberger, K. Rodgers, C. Naus
Differential Expression Of Gap Junctions In Neurons And Astrocytes Dervied From P19 Embryonal Carcinoma Cells, Daniel Belliveau, J. Bechberger, K. Rodgers, C. Naus
Daniel J. Belliveau
The P19 embryonal carcinoma cell line represents a pluripotential stem cell that can differentiate along the neural or muscle cell lineage when exposed to different environments. Exposure to retinoic acid induces P19 cells to differentiate into neurons and astrocytes that express similar developmental markers as their embryonic counterparts. We examined the expression of gap junction genes during differentiation of these stem cells into neurons and astrocytes. Untreated P19 cells express at least two gap junction proteins, connexins 26 and 43. Connexin32 could not be detected in these cells. Treatment for 96 hr with 0.3 mM retinoic acid induced the P19 …

Blocking Nerve Growth Factor Binding To The P75 Neurotrophin Receptor On Sympathetic Neurons Transiently Reduces Trka Activation But Does Not Affect Neuronal Survival, C. Lachance, Daniel Belliveau, P. Barker
Blocking Nerve Growth Factor Binding To The P75 Neurotrophin Receptor On Sympathetic Neurons Transiently Reduces Trka Activation But Does Not Affect Neuronal Survival, C. Lachance, Daniel Belliveau, P. Barker
Daniel J. Belliveau
Nerve growth factor interacts with the trkA tyrosine kinase receptor and with the p75 neurotrophin receptor. It is clear that trkA mediates most, if not all, of the stereotypical responses of sympathetic neurons to nerve growth factor but the role of the p75 neurotrophin receptor is unclear. In this study, we have asked whether a functional interaction between p75 neurotrophin receptor and trkA exists in primary sympathetic neurons by disrupting nerve growth factor binding to p75 neurotrophin receptor. Acute assays reveal that blocking antibodies directed against p75 neurotrophin receptor reduce nerve growth factor-mediated trkA tyrosine phosphorylation and reduce the amount …
Transgenic Mice Expressing The Intracellular Domain Of The P75 Neurotrophin Receptor Undergo Neuronal Apoptosis, M. Majdan, C. Lachance, A. Gloster, R. Aloyz, C. Zeindler, S. Bamji, A. Bhakar, Daniel Belliveau, J. Fawcett, F. Miller, P. Barker

We have asked whether p75NTR may play a role in neuronal apoptosis by producing transgenic mice that express the p75NTR intracellular domain within peripheral and central neurons. These animals showed profound reductions in numbers of sympathetic and peripheral sensory neurons as well as cell loss in the neocortex, where there is normally little or no p75NTR expression. Developmental loss of facial motor neurons was not observed, but induced expression of the p75NTR intracellular domain within adult animals led to increased motor neuron death after axotomy. Biochemical analyses suggest that these effects were not attributable to a p75NTR-dependent reduction in trk …

Haitian Education Under Siege: Democratization, National Development, And Social Reconstruction, Marc Prou
Haitian Education Under Siege: Democratization, National Development, And Social Reconstruction, Marc Prou
Marc E. Prou
From a national development perspective,the Haitian educational system presents an alarming picture. It is one in which too much is expected of too little, and in which results are sacrificed to bureacratic convenience. The facts are simple and irrefutable. Only a massive investment in human capital formation will bring economic and social progress in Haiti. Yet economic growth and industrial expansion rely on education as a key factor for human capital formation. The major dichotomy between the two is that education can influence national development only to the extent that individuals are able to put the interests of the nation …
Ngf And Neurotrophin-3 Both Activate Trka On Sympathetic Neurons But Differentially Regulate Survival And Neuritogenesis, Daniel Belliveau, I. Krivko, C. Lachance, J. Kohn, D. Rusakov, D. Kaplan, F. Miller
Ngf And Neurotrophin-3 Both Activate Trka On Sympathetic Neurons But Differentially Regulate Survival And Neuritogenesis, Daniel Belliveau, I. Krivko, C. Lachance, J. Kohn, D. Rusakov, D. Kaplan, F. Miller
Daniel J. Belliveau
In this report we examine the biological and molecular basis of the control of sympathetic neuron differentiation and survival by NGF and neurotrophin-3 (NT-3). NT-3 is as efficient as NGF in mediating neuritogenesis and expression of growth-associated genes in NGF-dependent sympathetic neurons, but it is 20-40-fold less efficient in supporting their survival. Both NT-3 and NGF induce similar sustained, long-term activation of TrkA, while NGF is 10-fold more efficient than NT-3 in mediating acute, short-term TrkA activity. At similar acute levels of TrkA activation, NT-3 still mediates neuronal survival two- to threefold less well than NGF. However, a mutant NT-3 …
Multilevel Latent Variable Modeling In Multiple Populations, Siek Khoo, B Muthén, J Gustafsson
Multilevel Latent Variable Modeling In Multiple Populations, Siek Khoo, B Muthén, J Gustafsson
Dr Siek Toon Khoo
Modeling is described for the simultaneous analysis of two-level data in several populations. A typical example is cluster sampling of students within schools, where schools of different types are represented, eg public and private schools. Multivariate measurements on each student are assumed to give rise to a latent variable model. Of interest is to study across-population differences and similarities with respect to the within- and between-group covariance matrices and with respect to the mean vector. The methodology is illustrated by a comparative analysis of achievement structures in Catholic and public schools.
