The STCC Science Teaching Intern Project

The Springfield Technical Community College (STCC) Science Teaching Intern Project was implemented as a pilot study to give community college students an opportunity to experience science teaching. At the same time, it provided seventh graders in inner city middle schools opportunities to interact with college students and to take advantage of science resources not usually available to them. Interns attended weekly meetings and participated in an all-day science field trip at the college. Most participants also made observations in a middle school science classroom and presented a science activity in the classroom. Not only did the project provide a partnership between STCC and two Springfield public schools, but it also involved interaction with the University of Massachusetts School of Education, since a doctoral candidate provided expertise in education methodology and in evaluation of the project. The project was evaluated by the interns, the two K-12 teachers, the seventh graders, and by the doctoral candidate. There was clear enthusiasm for the project provided by all the sources. The conversion of this project into a one-credit course is currently under development

Winter Anomaly of the Lower Ionosphere and Its Possible Causes

It is a well-known fact that in winter the midlatitude lower ionosphere differs considerably from that in summer. Attempts to explain the possible causes of the winter anomaly in the lower ionosphere were made. Integrated ground-based and rocket experiments were performed in the USSR. The rockets M-100B launched in Volgograd (psi = 48.7 deg N; lambda = 44.3 deg E; psi = 43.1 deg) provided weight profiles of electron density, wind and temperature. Radio wave absorption data obtained by a I method in Volgograd and F sub min parameters values obtained at a number of Soviet ionosone stations were used to determine the situation in the lower ionosphere. It was found that a correct interpretation of the midlatitude winter radio wave absorption changes is possible only if the whole spatial-time pattern of the event is taken into account

Self-selection patterns in Mexico-U.S. migration: the role of migration networks

This paper examines the role of migration networks in determining self-selection patterns of Mexico-U.S. migration. We first present a simple theoretical framework showing how such networks impact on migration incentives at different education levels and, consequently, how they are likely to affect the expected skill composition of migration. Using survey data from Mexico, we then show that the probability of migration is increasing with education in communities with low migrant networks, but decreasing with education in communities with high migrant networks. This is consistent with positive self-selection of migrants being driven by high migration costs, as advocated by Chiquiar and Hanson (2005), and with negative self-selection of migrants being driven by lower returns to education in the U.S. than in Mexico, as advocated by Borjas (1987)
