In an effort to exemplify marketing strategy and promotion this thesis focuses on a myriad of cultural differences that impact the way consumers are attracted to products and how they make purchasing decisions. It grasps advertising differences amongst the United States and Europe, more specifically the United Kingdom and France. In order to accurately decipher the marketing differences the thesis works to show the history of advertising, how culture broadly influences advertising, different advertising mediums and how they are used in …
The Un Response To The Turkish Cypriot Declaration Of Independence And Its Impact On The Cyprus Problem, Michael Barnes
The Un Response To The Turkish Cypriot Declaration Of Independence And Its Impact On The Cyprus Problem, Michael Barnes
Honors Capstones
This paper examines what role the UN played in the ethnic conflict between Greek and Turkish Cypriots after the Turkish Cypriots declared independence in 1983. The UN has been actively involved with ethnic conflict in the past 50 years and will continue to do so into the future. Examining the UN's policy towards the Turkish Cypriot secession will contribute to the understanding of the role the UN will play in future ethnic conflicts. How did the UN respond to the Turkish Cypriot Declaration of Independence and what impact did that response have on negotiations involving Greek Cypriots, Turkish Cypriots and …

On Trade Policies And Wage Disparity In Egypt: Evidence From Microeconomic Data, Chahir Zaki
Poverty, Gender, and Youth
This working paper assesses the extent to which trade barriers, including traditional tariff barriers, non-tariff measures, and red tape, affect wage disparity and employment in Egypt. Using a microeconomic dataset, the author assesses to what extent different trade barriers affected wage disparity and employment in Egypt. This disparity is studied in three dimensions: on gender (males vs. females), qualification (blue vs. white collar workers), and regional (urban vs. rural workers). Findings show that both non-tariff measures and red tape barriers have a higher impact than traditional tariffs on wage disparity and that women, urban workers, and blue collar workers are …

Sexuality Among Evangelical College Women, Rachel Keener Killam, Heather Davediuk Gingrich
Sexuality Among Evangelical College Women, Rachel Keener Killam, Heather Davediuk Gingrich
Growth: The Journal of the Association for Christians in Student Development
While some studies have examined the attitudes and perceptions of women with regard to their sexuality, none have investigated evangelical, female college students. This study explored attitudes and perceptions among eight evangelical Christian college women attending an evangelical university in the Western United States. Qualitative interviews were conducted and transcripts analyzed to determine underlying themes. Themes that emerged were (a) shame, (b) (c) fear, (d) ambivalence, (e) ignorance, (f ) lack of sexual subjectivity and agency, (g) presence of sexual subjectivity and agency, (h) same-sex attraction, (i) female sexuality as God-given and natural, and (j) the importance of open dialogue …
Community As A Redistricting Principle: Consulting Media Markets In Drawing District Lines, Jason C. Miller
Community As A Redistricting Principle: Consulting Media Markets In Drawing District Lines, Jason C. Miller
Indiana Law Journal
With the 2011 redistricting process poised to commence across the country, debates are raging as to who should draw district lines, how to keep those individuals from drawing them for partisan advantage, and the best way to draw minority districts. This paper addresses the largely overlooked area of media markets. Districts drawn to conform with media markets experience higher voter turnout. Moreover, linking a city and its economically-connected suburbs together is simply common sense. Discussing the impact of district conformity, or lack thereof, with media market boundaries on campaign strategy, news reporting, voter participation, grassroots organizing, and candidate recruitment, this …
Images Of Force: The Power Of Maps In Community Development, Jill M. Fraley
Images Of Force: The Power Of Maps In Community Development, Jill M. Fraley
Scholarly Articles
Recent trends in critical geography have drawn attention to the secret political lives of maps. Beneath a veneer of abstraction and scientific neutrality, maps are deeply political devices, embedding within them perspectives on what is important in a community, what are assets and what are liabilities, what is central and what is marginal. By drawing on the historical example of the mapping work of the Tennessee Valley Authority in the United States, this article examines the power of maps in community development, land use planning and natural resource allocation. This examination yields a lesson in the significance of the maps …

All 3 species were collected in the Socola railway yard in northeastern Romania; the specimens were deposited in the IASI Herbarium, at the University of Agricultural Sciences and Veterinary Medicine Iaşi. Their introduction was accidental, through the rail transport from the former USSR. The 3 species are perennial herbs, …
The Rule Of Law Through Its Economies Of Appearances: The Making Of The African Warlord, Kamari Maxine Clarke
The Rule Of Law Through Its Economies Of Appearances: The Making Of The African Warlord, Kamari Maxine Clarke
Indiana Journal of Global Legal Studies
The global reach of international law is now becoming relevant to the micromanagement of daily life. In postcolonial African states, everyday actions and their meanings are being opened up by the expansion of national jurisdiction into international jurisdiction. In relation to these changing technologies of managing shifting regimes of power, this article explores the ways that the spectacle of the rule of law is linked to the spectacle of capitalism. By examining the workings of victim and witness testimonies in the Special Court of Sierra Leone, I examine the ways that spectacles of law and articulations of suffering displace the …

Human Rights -- Latin America, Indigenous Peoples -- Latin America, Neoliberalism -- Latin America, Ethnicity.Gov: Global Governance, Indigenous Peoples, And The Right To Prior Consultation In Social Minefields, César Rodríguez-Garavito
Indiana Journal of Global Legal Studies
This article explores law's protagonism and effects in contemporary conflicts over development, natural resource extraction, and indigenous peoples' rights. It focuses on the sociolegal site where these conflicts have been most visible and acute: consultations with indigenous peoples prior to the undertaking of economic projects that affect them. I argue that legal disputes over prior consultation are part of a broader process of juridification of ethnic claims, which I call "ethnicity.gov." I examine the plurality of public and private regulations involved in this process and trace their affinity with the procedural logic of neoliberal global governance. I further argue that …

Model For Predicting The Impact Upon Economic Development Resulting From Highway Improvement Projects, Eric Thompson, Kanou Comlavi, Mallory Dimmit
Mid-America Transportation Center: Final Reports and Technical Briefs
The Nebraska Department of Roads (NDOR) has an interest in integrating state economic development impact as another factor in prioritizing transportation investments. Such efforts require the development of a comprehensive model that can be used to estimate a consistent final measure of economic development impact that can be readily integrated into existing prioritization formulas. This report summarizes the efforts of the University of Nebraska-Lincoln Bureau of Business Research (UNL-BBR) to develop such a model, by measuring the impact of expressway, viaduct, and other major investments projects around the state. Specifically, UNL-BBR developed an economic model to predict the economic impact …

Red band bidirectional reflectance factor data from the NASA MODerate resolution Imaging Spectroradiometer (MODIS) acquired over the southwestern United States were interpreted through a simple geometric–optical (GO) canopy reflectance model to provide maps of fractional crown cover (dimensionless), mean canopy height (m), and aboveground woody biomass (Mg ha−1) on a 250 m grid. Model adjustment was performed after dynamic injection of a background contribution predicted via the kernel weights of a bidirectional reflectance distribution function (BRDF) model. Accuracy was assessed with respect to similar maps obtained with data from the NASA Multiangle Imaging Spectroradiometer (MISR) and to contemporaneous …

United States National Aeronautics and Space Administration: Publications
Over the past decade, the role of multiangle remote sensing has been central to the development of algorithms for the retrieval of global land surface properties including models of the bidirectional reflectance distribution function (BRDF), albedo, land cover/dynamics, burned area extent, as well as other key surface biophysical quantities impacted by the anisotropic reflectance characteristics of vegetation. In this study, a new retrieval strategy for fine-to-moderate resolution multiangle observations was developed, based on the operational sequence used to retrieve the Moderate Resolution Imaging Spectroradiometer (MODIS) Collection 5 reflectance and BRDF/albedo products. The algorithm makes use of a semiempirical kernel-driven bidirectional …

United States National Aeronautics and Space Administration: Publications
Many studies have been conducted to demonstrate the ability of hyperspectral data to discriminate plant dominant species. Most of them have employed the use of empirically based techniques, which are site specific, requires some initial training based on characteristics of known leaf and/or canopy spectra and therefore may not be extendable to operational use or adapted to changing or unknown land cover. In this paper we propose a physically based approach for separation of dominant forest type using hyperspectral data. The radiative transfer theory of canopy spectral invariants underlies the approach, which facilitates parameterization of the canopy reflectance in terms …

United States National Aeronautics and Space Administration: Publications
In this paper, we explored fusion of structural metrics from the Laser Vegetation Imaging Sensor (LVIS) and spectral characteristics from the Airborne Visible Infrared Imaging Spectrometer (AVIRIS) for biomass estimation in the Sierra Nevada. In addition, we combined the two sensors to map species-specific biomass and stress at landscape scale. Multiple endmember spectral mixture analysis (MESMA) was used to classify vegetation from AVIRIS images and obtain sub-pixel fractions of green vegetation, non-photosynthetic vegetation, soil, and shade. LVIS metrics, AVIRIS spectral indices, and MESMA fractions were compared with field measures of biomass using linear and stepwise regressions at stand (1 ha) …

In this study we use the 500 m Moderate Resolution Imaging Spectroradiometer (MODIS) Bidirectional Reflectance Distribution Function (BRDF) product to develop multivariate linear regression models that estimate canopy heights over study sites at Howland Forest, Maine, Harvard Forest, Massachusetts and La Selva Forest, Costa Rica using (1) directional escape probabilities that are spectrally independent and (2) the directional spectral reflectances used to derive the directional escape probabilities. These measures of canopy architecture are compared with canopy height information retrieved from the airborne Laser Vegetation Imaging Sensor (LVIS). Both the escape probability and the directional reflectance approaches achieve good results, with …

Surface energy budget is an important factor in weather and climate processes. To estimate the errors in satellite-retrieved surface radiation budget over the interior of China, instantaneous-footprint surface radiation fluxes from the Terra/Aqua FLASHFlux SSF product are compared with the measurements taken at the Semi-Arid Climate and Environment Observatory of Lanzhou University (SACOL) from July 2008 to March 2010. Validation is performed separately for different conditions: clear-sky and cloudy-sky, daytime and nighttime for four seasons. Differences between the FLASHFlux CERES shortwave radiation flux and surface measurements have larger standard deviations in cloudy-sky conditions than in clear-sky conditions, indicating that cloud …

University of Nebraska-Lincoln Libraries: Faculty Publications
In the library literature, a great deal of interest in patron-driven collection development has recently been expressed, especially in those programs that link acquisitions with interlibrary loan. However, the implementation of such programs has been limited, at least in part because of concerns over the potential for wasteful spending. The authors will attempt to address this common concern by assessing whether monies spent via a patron-driven acquisitions program were more or less effective than monies spent via traditional modes of acquisition.

This work proposes a method for detecting inundation between semi-diurnal low and high water conditions in the northern Gulf of Mexico using high-resolution satellite imagery. Radarsat 1, Landsat imagery and aerial photography from the Apalachicola region in Florida were used to demonstrate and validate the algorithm. A change detection approach was implemented through the analysis of red, green and blue (RGB) false colour composites image to emphasise differences in high and low tide inundation patterns. To alleviate the effect of inherent speckle in the SAR images, we also applied ancillary optical data. The flood-prone area for the site was delineated …

United States Department of Commerce: Staff Publications
Despite their importance as evolutionary and ecological model systems, the phylogenetic relationships among gasterosteiforms remain poorly understood, complicating efforts to understand the evolutionary origins of the exceptional morphological and behavioural diversity of this group. The present review summarizes current knowledge on the origin and evolution of syngnathids, a gasterosteiform family with a highly developed form of male parental care, combining inferences based on morphological and molecular data with paleontological evidence documenting the evolutionary history of the group. Molecular methods have provided new tools for the study of syngnathid relationships and have played an important role in recent conservation efforts. Despite …

Can We Manage For Resilience? The Integration Of Resilience Thinking Into Natural Resource Management In The United States, Melinda Harm Benson, Ahjond S. Garmestani
United States Environmental Protection Agency: Publications
The concept of resilience is now frequently invoked by natural resource agencies in the US. This reflects growing trends within ecology, conservation biology, and other disciplines acknowledging that social–ecological systems require management approaches recognizing their complexity. In this paper, we examine the concept of resilience and the manner in which some legal and regulatory frameworks governing federal natural resource agencies have difficulty accommodating it. We then use the U.S. Forest Service’s employment of resilience as an illustration of the challenges ahead.

Prototyping An Online Wetland Ecosystem Services Model Using Open Model Sharing Standards, Min Feng, Shuguang Liu, Ned H. Euliss Jr., Claudia Young, David M. Mushet
United States Geological Survey, Northern Prairie Wildlife Research Center: Publications
Great interest currently exists for developing ecosystem models to forecast how ecosystem services may change under alternative land use and climate futures. Ecosystem services are diverse and include supporting services or functions (e.g., primary production, nutrient cycling), provisioning services (e.g., wildlife, groundwater), regulating services (e.g., water purification, floodwater retention), and even cultural services (e.g., ecotourism, cultural heritage). Hence, the knowledge base necessary to quantify ecosystem services is broad and derived from many diverse scientific disciplines. Building the required interdisciplinary models is especially challenging as modelers from different locations and times may develop the disciplinary models needed for ecosystem simulations, and …
