Description
An array of north-striking, left-stepping, active normal faults is situated along the southwestern margin of the Gulf of California. This normal fault system is the marginal fault system of the oblique-divergent plate boundary within the Gulf of California. To better understand the role of upper-crustal processes during development of an obliquely rifted plate margin, gravity surveys were conducted across the normal-fault-bounded basins within the gulf-margin array and, along with optically stimulated luminescence dating of offset surfaces, fault-slip rates were estimated and fault patterns across basins were assessed, providing insight into sedimentary basin evolution. Additionally, detailed geologic and geomorphic maps were constructed along two faults within the system, leading to a more complete understanding of the role of individual normal faults within a larger array. These faults slip at a low rate (0.1-1 mm/yr) and have relatively shallow hanging wall basins (~500-3000 m). Overall, the gulf-margin faults accommodate protracted, distributed deformation at a low rate and provide a minor contribution to overall rifting. Integrating figures with text can lead to greater science learning than when either medium is presented alone. Textbooks, composed of text and graphics, are a primary source of content in most geology classes. It is essential to understand how students approach learning from text and figures in textbook-style learning materials and how the arrangement of the text and figures influences their learning approach. Introductory geology students were eye tracked while learning from textbook-style materials composed of text and graphics. Eye fixation data showed that students spent less time examining the figure than the text, but the students who more frequently examined the figure tended to improve more from the pretest to the posttest. In general, students tended to examine the figure at natural breaks in the reading. Textbook-style materials should, therefore, be formatted to include a number of natural breaks so that learners can pause to inspect the figure without the risk of losing their place in the reading and to provide a chance to process the material in small chunks. Multimedia instructional materials should be designed to support the cognitive processes of the learner.

Description
Since the collapse of the Medellin Cartel in Colombia in 1993, the Mexican drug cartels have been increasing in strength and international presence. Along with the organization's political and economic involvement, a deeply rooted culture has been developing. Three distinct time periods define this culture: pre-Medellin Cartel collapse (1970s-1993), post-Medellin Cartel Collapse (1993-2006) and post-President Calderon's Drug War announcement (2006-present day). More specifically, the history and fascination with the cartel is documented in songs, known as narcocorridos, which celebrate and support the drug cartels. The science of political sociology addresses the power relationship that exists between a state, its citizens, and the state's social groups. This study investigates the political sociology of each period, specifically how society viewed the cartel and their roles within the cartel. I argue that the narcocorridos accurately describe the evolution of narcoculture in Mexican society. This study consists of analyses of narcocorrido song lyrics, the political sociology of each time period, and finally, the societal perception of the drug cartel. First, I will evaluate the most popular songs' lyrics of the three defining time periods in the Mexican Drug Cartel history. Next, I will analyze the lyrics and determine whether or not they accurately reflect the political sociological features of the time period. Last, I will discuss what the societal perceptions of being associated with the cartel were during each time period. This study concludes by hypothesizing what the future of narcocorriodos will be. This prediction will demonstrate how the songs will continue to reflect the political sociology of the time period, including the societal attitudes towards the cartel.
