The research in traffic flow and safety has proceeded on two different tracks. The traffic flow research has focused on macroscopic aspects and aggregate behavior, while safety research has focused on the traveller's microscopic view of the transportation system. This dichotomy of research methodology has made it difficult to study many issues in intelligent vehicle highway systems in an integr...

As of December 2011, 13 states have adopted an in-state resident tuition (IRT) policy that provides in-state tuition to undocumented immigrants and several other states are considering similar legislation. While previous research focuses on how IRT policies affect college entry and attainment, this study examines the effect these policies have on high school dropout behavior. Using the Current ...

Chromatic assimilation is the shift in color appearance toward nearby light. Assimilation was measured using nearby light with time-varying chromaticity. This light induced time-varying assimilation within the test area. Assimilation was quantified by the amplitude of temporally varying test-area light--in counter-phase to the induced assimilation--required to null the assimilation. Unlike prev...

Frontier Issues of the Political Economy of Migration Migration has a strong economic impact on the sending and host countries. Since individuals and groups do not benefit equally from migration, interest groups emerge to protect and take care of their narrow self-interests and compete for rents generated by migration. Narrow selfinterests may be present not only for interest groups but also fo...

The paper deals with agricultural land problems in Bulgaria that will impede the implementation of the Common Agricultural Policy (CAP) and the assimilation of financial resources from the EU Structural Funds. Some of the major problems are: the unfinished process of identification of land ownership and division of ownership on the restituted land between heirs, the lack of land property docume...

stomata are closed by moisture stress, reducing carbon assimilation and yield production with dry land agriculture. relative 13c to 12c molar ratio assimilation by a plant is a function of time stomata remain open during plant life time, itself a function of moisture stress. the purpose of this study was to test the existence of any relationship between stomatal conductance and assimilation rat...

■ Abstract This review examines research on the assimilation of immigrant groups. We review research on four primary benchmarks of assimilation: socioeconomic status, spatial concentration, language assimilation, and intermarriage. The existing literature shows that today’s immigrants are largely assimilating into American society along each of these dimensions. This review also considers direc...

Migrant Ethnic Identity: Concept and Policy Implications With globalization, the size of migration and the value of ethnicity is rising. Also Cyprus undergoes a strong process of change while experiencing large inflows of migration. The paper investigates the challenges and the potentials of migration from a European Union perspective. It advocates for a new concept to measure the ethnic identi...
