Who Are "The Japanese"?: Negotiation Of Identity Among Nikkei In Brazil, Chihiro Nagasue

Masters Theses

When Japanese immigrants arrived in Brazil in the beginning of the 20th century, they recognized, for the first time, that they were "Japanese" and different from other ethnic people since it was rare for them to meet ethnically foreign people in Japan. In the ethnically and linguistically foreign country of Brazil, the Nikkei have had to constantly redefine their identity by resisting and accommodating dominant pressures and ideologies such as the Brazilian assimilation policies before and during the Second World War as well as the essentialist ideology of Nihonjinron (what it means to be Japanese). As a result of globalization, …

Eating Ethnicity: Examining 18th Century French Colonial Identity Through Selective Consumption Of Animal Resources In The North American Interior, Rory J. Becker

Masters Theses

Cultural identities can be created and maintained through daily practice and food consum.ption is one such practice. People need food in order to survive, but the types of food they eat are largely determined by the interaction of culture and their environment. By approaching the topic of subsistence practices as being culturally constituted, the study of foodways provides an avenue to examine issues of cultural identity through selective consumption. Eating certain foods to the exclusion of others is one method for establishing social distance between peoples and is simultaneously a reflection of this relationship and the types of interactions that …

Resonant And Non-Resonant Inelastic X-Ray Scattering Of Copper Phthalocyanine, Michelle Deleene Tuel-Benckendorf

Masters Theses

With the ever-changing demands of technology and the desire to use new materials to replace the old, researchers have the job to not only find alternative materials, but also understand their properties. There continues to be extensive research in the properties of organic semiconductors, for use in many microelectronic applications. There is very little known about the excitation properties of these materials. For my research, I have chosen to study the electronic excitations of copper phthalocyanine (CuPc), one specific organic semiconductor. To do this, we used resonant and non-resonant inelastic x-ray scattering to measure the evolution of excitations as a …

The Role Of Economic, Political, And Cultural Factors In Immigration Policy In France, The United Kingdom, And Germany, Sheri L. Rogers

Masters Theses

Immigration policy has been a crucial issue facing all Western European countries for decades; however, it has recently become an even greater concern. Much of the literature argues that shifts in immigration policy correspond with shifts in economic conditions or the power of far-right parties. Others argue that immigration policy is primarily a cultural issue, although very little research has been done to address the role of specific cultural factors in different countries.

This paper looks at the evolution of immigration policy in France, the United Kingdom, and Germany, and addresses the question of why immigration policies in each country …

Metal Ion Imprinted Polymers For Biomolecular Recognition, Len A. Harris

Masters Theses

Protein recognition by HPLC, based on histidine residues, was achieved by incorporating a copper chelating ligand covalently bonded to a polystyrene/divinyl benzene substrate, into column packing. The metal ion was bonded to the substrate in two ways: randomly, where the copper was bound to the ligand after the substrate polymerization and imprinted, where the copper was bound to the ligand before the substrate polymerization. The effect of this templating was measured by protein separation parameters of the resulting HPLC chromatographs. The hypothesis of this thesis is the imprinted substrate will have a higher copper content, and with coppers affinity toward …

Superimposition And Withdrawal Of Tangible Consequences As A Treatment For Automatically Reinforced Problem Behaviors, Tina M. Sidener

Masters Theses

Tangible superimposition and withdrawal is a reductive procedure in which a new stimulus is delivered following behavior already maintained by a different controlling stimulus. The new stimulus is then removed in an attempt to reduce behavior. The current investigation sought to extend previous research on this procedure by evaluating its efficacy and durability as a treatment for stereotypy in three children diagnosed with autism. First, automatic reinforcement functions for stereotypic behaviors were identified via functional analyses. Next, for two participants, tangible items were delivered contingent upon stereotypy and then subsequently withdrawn. When the superimposition procedure proved ineffective, environmental enrichment was …

A Comparison Of Human Femoral Neck Cortical Bone: Walkers Vs. Non-Walkers, Meghan M. Moran

In addition, quantitative measures were obtained from the samples, including an index of control (Laminack & Wood, 1996) and a percentage correct. Analyses were also used to test the effectiveness of using a writing lab approach (Nelson, Bahr & Van Meter, 2004) on spelling development. During the last half of second grade, all 32 students received intervention guided by the …

Understanding Ethno-Nationalism: Sikh Diasporic Imaginings In Southwest Michigan, Rory G. Mccarthy

Masters Theses

Diaspora as a category is both useful and troublesome for researchers in the discipline of anthropology. It is useful, for it allows anthropologists to approach cultural studies from a position that recognizes flaws in the conception of culture as geographically bounded. Studying diasporic populations, therefore, enables anthropologists to apply new theoretical approaches to culture, without reifying and essentializing social practices. Conversely, using diaspora as a category can homogenize groups by glossing over differences in ethnicity, religion, and migratory expenence.

This study aims at bettering the understanding of diversity within a diasporic population by examining the role that religion plays in …

An Intensive Surface Collection And Intrasite Spatial Analysis Of The Archaeological Materials From The Coy Mound Site (3ln20), Central Arkansas, William Glenn Hill

Masters Theses

Surface collected materials from the Coy Mound site (3LN20), Lonoke County, Arkansas, are utilized in order to address questions regarding site temporal occupations, resource utilization, internal site configuration, and the socio-political organization of the Baytown-Coles Creek period Plum Bayou culture. Artifact distribution plots revealed the presence of a mound and plaza site configuration in addition to potential domestic and off-mound midden deposits. While the site organizational plan has implications for a hierarchical socio-political organization, the absence of inter- and intrasite variability in ceramic types and lithic materials support the hypothesis that limited social differentiation was present in Plum Bayou culture …
