Racial Profiling: Legal and Constitutional Issues
Racial profiling is the practice of targeting individuals for police or security detention based on their race or ethnicity in the belief that certain minority groups are more likely to engage in unlawful behavior. Examples of racial profiling by law enforcement agencies suggest that minorities are disproportionately the subject of security-related practices. The issue has periodically attracted congressional interest and several courts have considered the constitutional ramifications of the practice as an "unreasonable search and seizure" under the Fourth Amendment and, more recently, as a denial of the Fourteenth Amendment's equal protection guarantee. A variety of federal and state statutes provide potential relief to individuals who claim that their rights are violated by race-based law enforcement practices and policies.
Using Cultural Cognition for Learning English: A Mexican Immigrant Family's Perspective
Using Cultural Cognition for Learning English: A Mexican Immigrant Family’s Perspective by Cherri Louise Brown MBA, New York Institute of Technology, 2008 BA, Mount Holyoke College, 2001 Dissertation Submitted in Partial Fulfillment of the Requirements for the Degree of Doctor of Philosophy Education Psychology Walden University October 2016 Abstract The research problem focused on the 11 million Mexican immigrant families in the United States who speak little or no English. Their stated needs for English literacy, socioeconomic and academic success, and the increasing calls for xenophobic legislation throughout the nation indicated a need to investigate alternative pedagogies to compel positive social change through language fluency.

Their stated needs for English literacy, socioeconomic and academic success, and the increasing calls for xenophobic legislation throughout the nation indicated a need to investigate alternative pedagogies to compel positive social change through language fluency. In this case study, Mexican immigrant second-language learners and their descendants were asked how they wanted to learn English and if using native culture as a learning tool would help in achieving their literacy goals. Prior researchers had not asked those questions. Three adults from a 3generation Mexican immigrant family living in Florida gave interviews to address this gap. The participants, 2 of whom were native Spanish speakers, were recruited via a Facebook call for participation, and interviews were conducted by telephone. Cultural theory served as a conceptual framework for understanding the relationship between culture and language, and for interpreting and respecting participants’ articulations of their experiences and opinions. Analyses of interviews and language background questionnaires were completed using pattern matching and SPSS, respectively. The key finding was that participants agreed a cultural pedagogy would be helpful in learning English. A recommendation is made to implement an experimental teaching study using cultural pedagogy as its framework. Achieving positive social change begins with removing the barriers of cultural language discrimination and allowing immigrants to reach their stated goals without loss of their cultural heritage.

THE PERFORMANCE OF STEADY DETONATION ENGINES
Propulsion systems driven by steady normal detonations are studied. The practical di‐culties associated with stabilizing a detonation wave are highlighted. The requirement on the freestream total enthalpy is considered in parallel with efiects such as condensation or auto-ignition of the fuel-air mixture and limitations associated with fuel sensitivity to detonation. A criterion for detonation stabilization is formulated and applied to an analytical treatment of a detonation ramjet and a detonation turbojet, which are the respective analogs of the ramjet and the turbojet using detonative combustion. The performance of these engines is evaluated and compared to the ideal ramjet and turbojet models for hydrogen and JP10. A limitation is placed on the maximum total temperature allowed in the combustor, based on material considerations. The results show that steady detonation engines have a small thrust-producing range, due to the requirements for detonation stabilization. Their performance is always lower than that of the conventional ramjet and turbojet because of the total pressure loss across the detonation.
