Informed by Bronfenbrenner’s ecological model of development, this mixed-methods study’s aims are to: (1) describe rural Latino/a adolescents’ ( N = 62) narratives and lived social experiences in the context of rurality, and (2) examine their personal networks to better understand their social interactions (subset of 30 adolescents). Rural Latino/a adolescents move in limited social circles and experience geographic, cultural, and social isolation due to immigration status problems, socioeconomic issues, racial discrimination, and family dynamics. This limitation is reflected by personal networks that tend to be homogenous in terms of ethnicity, age, and sociodemographic characteristics. School, although characterized by weak social ties often disconnected from community and family contacts, emerged as the dominant context of sociability where adolescents build their social identity outside the circle of dense family ties. Findings suggest a critical need for interventions to reduce isolation and enhance social connectedness between family, school, and rural community in this population.

Described in this chapter is an innovative online course that was created to support Spanish language students whose study abroad program was cancelled during the summer of 2020 due to the pandemic. While many students were able to enroll quickly in summer online language course offerings at their home campus to substitute for their study abroad coursework, students who were scheduled to complete field experiences in Spain as part of their certificate in Spanish for Professionals were unable to do so. In response to this problem, the author created an online professional practicum course to substitute for students' service-learning course in Spain. The design, development, and delivery of the online course, which featured a virtual language exchange between students in the U.S. and Spain, is the focus of the present chapter. Also described in this chapter is the conceptual framework that underpins sound instructional design for online communicative language teaching.

The Design Development and Implementation Program (DDIP) evolved as a result of an organized progression of In-Service Engineering (ISE) responsibilities required to implement improvements to Gas Turbine Generator Sets (GTGS) in the U.S. Navy. The DDIP was established to bring a design concept, whether it be to correct a problem or to make a design improvement, from the drawing board through testing and development to the implementation of a Technical Directive as quickly as possible. Presently all engineering improvements on U.S. Navy Gas Turbine Generator Sets are implemented through the DDIP. Providing this central point of engineering has helped the Naval Sea Systems Command implement improvements in a well tested and timely manner. This paper describes the sequential processes in the DDIP methodology and further discusses specific engineering problems and solutions using the DDIP process.

Mutual Agreement

This program has been organized by the EMSA to commensurate the 50th anniversary of the experimental verification of the wave nature of the electron. Davisson and Germer in the U.S. and Thomson and Reid in Britian accomplished this at about the same time. Their findings were published in Nature in 1927 by mutual agreement since their independent efforts had led to the same conclusion at about the same time. In 1937 Davisson and Thomson shared the Nobel Prize in physics for demonstrating the wave nature of the electron deduced in 1924 by Louis de Broglie.The Davisson experiments (1921-1927) were concerned with the angular distribution of secondary electron emission from nickel surfaces produced by 150 volt primary electrons. The motivation was the effect of secondary emission on the characteristics of vacuum tubes but significant deviations from the results expected for a corpuscular electron led to a diffraction interpretation suggested by Elasser in 1925.

Examination of sand grain surfaces from early Paleozoic sandstones by electron microscopy reveals a variety of secondary effects caused by rock-forming processes after final deposition of the sand. Detailed studies were conducted on both coarse (≥0.71mm) and fine (=0.25mm) fractions of St. Peter Sandstone, a widespread sand deposit underlying much of the U.S. Central Interior and used in the glass industry because of its remarkably high silica purity.The very friable sandstone was disaggregated and sieved to obtain the two size fractions, and then cleaned by boiling in HCl to remove any iron impurities and rinsed in distilled water. The sand grains were then partially embedded by sprinkling them onto a glass slide coated with a thin tacky layer of latex. Direct platinum shadowed carbon replicas were made of the exposed sand grain surfaces, and were separated by dissolution of the silica in HF acid.
