This thesis examines why some governments and rebel organizations but not others recruit children to be child soldiers. The theory posits that if a country fights in a civil war of long duration, armed groups are more likely to recruit children as soldiers. I find that the probability of child soldier recruitment increases when a country experiences following conditions: a longer duration of civil war, a large proportion of battle deaths, a large number of refugees, a high infant mortality rate, and the presence of alluvial diamonds. An increase in education expenditures and civil liberties would decrease the probability of child soldier recruitments.

Throughout the colonial period, the Spanish attempted to Hispanicize the Indians along the northern frontier of New Spain. The conquistador, the missionary, the civilian settler, and the presidial soldier all took part in this effort. At La Junta de los Rios, a fertile area inhabited by both sedentary and semi-sedentary Indians, each of these institutions played a part in fundamentally changing the region and its occupants. This research, relying primarily on published Spanish source documents, sets the effort to Hispanicize La Junta in the broader sphere of Spain's frontier policy.

Traditional histories of the Texas frontier overlook a crucial component: efforts to defend Texas against Indians would have been far less successful without the contributions of Indian allies. The government of Texas tended to use smaller, nomadic bands such as the Lipan Apaches and Tonkawas as military allies. Immigrant Indian tribes such as the Shawnee and Delaware were employed primarily as scouts and interpreters. Texas, as a result of the terms of her annexation, retained a more control over Indian policy than other states. Texas also had a larger unsettled frontier region than other states. This necessitated the use of Indian allies in fighting and negotiating with hostile Indians, as well as scouting for Ranger and Army expeditions.

Mexico's cultural norms have been the subject of repeated inquiries because democratic and authoritarian patterns appear concomitantly. However, few have focused on the potential demographic and contextual sources of these divergent results. This study attempts to clarify the sources of Mexico's political culture, and then determine the extent to which these factors affect political participation. Statistical analysis of a LAPOP dataset from 2006 makes limited progress to this end. The sources of Mexican political culture remain somewhat a mystery, although some intriguing results were found. Most notably, demographic traits appear to have little influence on political culture variables and political participation rates in Mexico. In fact, political culture norms and political participation appears consistent across Mexico's infamous social and economic lines.
