An Empirical Note on the Social and Geographic Correlates of Mexican Migration to the Southern United States
This research empirically examines differences in the socioeconomic correlates of Mexican migrants to the southern region of the United States. More specifically, the research considers differences between Mexican immigrants choosing the South and those choosing other U.S. destinations. Using general estimating equations, the study provides evidence that several characteristics distinguish the stream of recent migrants choosing southern destinations. Notably, rural origins as well as rural destinations have substantial explanatory power. The results also show that immigrants to the South are likely to be pioneers in the sense that they do not have strong family-specific migration capital and are likely to be from a community without a long history of sending migrants to the United States. Immigrants choosing the South are also more likely to be undocumented. Additionally, they are far more likely to have arrived following implementation of NAFTA. Ownership of houses is also a distinguishing feature of these migrants
An Empirical Examination of Characteristics of Mexican Migrants to Metropolitan and Nonmetropolitan
ABSTRACT This research examines differences between those Mexican migrants choosing metropolitan destinations and those choosing destinations outside metropolitan areas of the United States. Using general estimating equations, the study presents data indicating that since the 1960s migrants choosing rural destinations are less fluent in English, slightly older, much less educated, far more likely to be unskilled, more likely to be married, and more likely to be undocumented. The picture is more complex when consideration is restricted to those migrants arriving in rural areas since the passage of the North American Free Trade Agreement. These migrants are far more likely to be single, have more education but have less English fluency, have less work experience, and have less family experience with migration to the United States. They are more likely to come from small towns and rural areas of Mexico
Creating E-Textile Activities in a Textile Design Course to Engage Female Middle School Students in STEM Learning: An Undergraduate Design Experience
Widespread agreement exists that the United States faces a serious challenge in the areas of science, technology, engineering, and mathematics (STEM). There is a particular deficit of females (Watt, 2010) and members of underserved groups like rural populations (Smith, Nelson, Trygstad, & Banilower, 2013) who are interested in STEM topics and qualified to pursue STEM careers. Initiatives are needed to encourage more students, especially females and rural students, to go into STEM fields. In this project, e-textile activities were designed by a senior level undergraduate textile design class to engage female middle-school students in STEM learning. E-textile activities have the potential to increase enjoyment of and interest in STEM activities, taking STEM courses, consideration of STEM careers, and confidence in STEM ability
Refinement of the convex shape model and tumbling spin state of (99942) Apophis using the 2020-2021 apparition data
Context. The close approach of the near-Earth asteroid (99942) Apophis to Earth in 2029 will provide a unique opportunity to examine how the physical properties of the asteroid could be changed due to the Eartha's gravitational perturbation. As a result, the Republic of Korea is planning a rendezvous mission to Apophis. Aims. Our aim was to use photometric data from the apparitions in 2020 2021 to refine the shape model and spin state of Apophis. Methods. Using thirty-six 1-to 2-meter-class ground-based telescopes and the Transiting Exoplanet Survey Satellite, we carried out a photometric observation campaign throughout the 2020 2021 apparition. The convex shape model and spin state were refined using the light-curve inversion method. Results. According to our best-fit model, Apophis is rotating in a short-axis mode with rotation and precession periods of 264.178 h and 27.38547 h, respectively. The angular momentum vector orientation of Apophis was found to be (275, 85) in the ecliptic coordinate system. The ratio of the dynamic moments of inertia of this asteroid was fitted to Iaa:a Iba:a Ica =a 0.64a:a 0.97a:a 1, which corresponds to an elongated prolate ellipsoid. These findings regarding the spin state and shape model can be used to both design the space mission scenario and investigate the impact of the Eartha's tidal force during close encounters
