Applied Mathematics & Information Sciences

In this paper, lower semi-continuous functions are used to extend Ekeland’s variational principle to the class of partial metric spaces. As consequences of our results, we obtain some fixed point theorems of Caristi and Clarke types.

Discovering Mesoscopic-Level Structural Patterns On Social Networks: A Node-Similarity Perspective, Qing Cheng, Zhong Liu, Jincai Huang, Guangquan Cheng

Applied Mathematics & Information Sciences

Structural pattern analysis is of fundamental importance as it provides a novel perspective on illustration of the relationship between structure and function, as well as to understand the dynamics, of social networks. So far, scientists have uncovered a multitude of structural patterns ubiquitously existing in social networks in different levels, they may be microscopic, mesoscopic or macroscopic. Our work mainly characterizes the mesoscopic-level structural patterns on social networks from the node-similarity viewpoint and reviews some latest representative methods, focusing on the improved methods of community measure and community structure detection, role discovery methods, as well as the structural group discovery …

Assessing The Cultural In Culturally Sensitive Printed Patient-Education Materials For Chinese Americans With Type 2 Diabetes, Evelyn Y. Ho, H Tran, Catherine A. Chesla

Communication Studies

Type 2 diabetes affects Chinese Americans at an alarming rate. To address this health disparity, research in the area of cultural sensitivity and health literacy provide useful guidelines for creating culturally appropriate health education. In this article, we use discourse analysis to examine a group of locally-available, Chinese and English language diabetes print documents from a surface and deep structure level of culture. First, we compared these documents to research findings about printed health information to determine if and how these documents apply current best practices for health literacy and culturally appropriate health communication. Second, we examined how diabetes as …

Mobile Nurse Practitioner: A Pilot Program To Address Service Gaps Experienced By Homeless Individuals, Joan Alviar Fraino

Nursing and Health Professions Student Research and Publications

An estimated 2.3 to 3.5 million individuals are homeless in the United States, many of whom have chronic medical and mental illnesses. Underserved individuals who are homeless experience gaps in services, resulting in poor health care outcomes and readmission to the hospital setting, often presenting in crisis through the emergency department. The financial state of hospitals is negatively impacted by the burden of patients returning to the hospital due to unresolved issues. The current article presents the role of a psychiatric-mental health nurse practitioner as part of a pilot program, Opportunity Village Mobile Health, that provides a comprehensive approach to …

Argentina's Trials: New Ways Of Writing Memory, Susana Kaiser

Media Studies

The last Argentine dictatorship (1976–1983) left a legacy of an estimated 30,000 desaparecidos (disappeared people). Three decades later, the wall of impunity is now being torn down. Trials are spreading across Argentina and hundreds of repressors are being judged. These trials are public spaces for collective memory making, political arenas for competing memory battles, and forums in which new information and perspectives about what happened under state terrorism continually emerge. Through the testimonies of survivors and the claims of the defense teams we gain new knowledge about the level and scope of the human rights abuses, how the repressive apparatus …

Parental Feeding Practices And Child Weight Status In Mexican American Families: A Longitudinal Analysis, Jeanne M. Tschann, Suzanna M. Martinez, Carlos Penilla, Steven E. Gregorich, Lauri A. Pasch, Cynthia L. De Groat, Elena Flores, Julianna Deardorff, Louise C. Greenspan, Nancy F. Butte

School of Education Faculty Research

Parental feeding practices are thought to influence children's weight status, through children's eating behavior and nutritional intake. However, because most studies have been cross-sectional, the direction of influence is unclear. Moreover, although obesity rates are high among Latino children, few studies of parental feeding practices have focused on this population. This 2-year longitudinal study examined mutual influences over time between parental feeding practices and children's weight status, in Mexican American families with children 18 years old at baseline. Mothers (n = 322) and fathers (n = 182) reported on their feeding practices at baseline, 1-year follow-up, and 2-year follow-up. Weight …

Doma's Demise: A Victory For Non-Heterosexual Binational Families, Daniela Domínguez

Psychology

An unprecedented number of American citizens faced the challenge o f being in a nonheterosexual binational relationship when the Defense o f Marriage Act (DOMA) was the law of the land. Although immigration laws are based on the principle o f family unification, under previous federal law lesbian, gay and bisexual Americans were not able to sponsor their samesex foreign national partners for residency in the United States. Consequently, an estimated 36,000 couples faced the threat of family separation because Am erica’s immigration policies narrowed the definition of “family” to exclude same-sex couples and their children. Despite the fact that …

The Contribution Of Methionine To The Stability Of The Escherichia Coli Metniq Abc Transporter-Substrate Binding Protein Complex, P. Nguyen, N. Kadaba, J. Y. Lai, Janet G. Yang, D. C. Rees

Chemistry Faculty Publications

Despite the ubiquitous role of ATP-binding cassette (ABC) importers in nutrient uptake, only the Escherichia coli maltose and vitamin B₁₂ ABC transporters have been structurally characterized in multiple conformations relevant to the alternating access transport mechanism. To complement our previous structure determination of the E. coli MetNI methionine importer in the inward facing conformation (Kadaba et al. (2008) Science 321, 250–253), we have explored conditions stabilizing the outward facing conformation. Using two variants, the Walker B E166Q mutation with ATP+EDTA to stabilize MetNI in the ATP-bound conformation and the N229A variant of the binding protein MetQ, shown in …

The Allosteric Regulatory Mechanism Of The Escherichia Coli Metni Methionine Atp Binding Cassette (Abc) Transporter, Janet G. Yang, D. C. Rees

Chemistry Faculty Publications

The MetNI methionine importer of Escherichia coli, an ATP binding cassette (ABC) transporter, uses the energy of ATP binding and hydrolysis to catalyze the high affinity uptake of d- and l-methionine. Early in vivo studies showed that the uptake of external methionine is repressed by the level of the internal methionine pool, a phenomenon termed transinhibition. Our understanding of the MetNI mechanism has thus far been limited to a series of crystal structures in an inward-facing conformation. To understand the molecular mechanism of transinhibition, we studied the kinetics of ATP hydrolysis using detergent-solubilized MetNI. We find that transinhibition is …

School of Natural Resources: Faculty Publications

“EEFlux” is an acronym for ‘Earth Engine Evapotranspiration Flux.’ EEFlux is based on the operational surface energy balance model “METRIC” (Mapping ET at high Resolution with Internalized Calibration), and is a Landsat-imagebased process. Landsat imagery supports the production of ET maps at resolutions of 30 m, which is the scale of many human-impacted and human-interest activities including agricultural fields, forest clearcuts and vegetation systems along streams. ET over extended time periods provides valuable information regarding impacts of water consumption on Earth resources and on humans. EEFlux uses North American Land Data Assimilation System hourly gridded weather data collection for energy …

Fitting Measured Evapotranspiration Data To The Fao56 Dual Crop Coefficient Method, R G. Allen, Ayse Kilic, Andrew Suyker, Jane A. Okalebo

School of Natural Resources: Faculty Publications

The FAO-56 publication of the UN Food and Agriculture Organization contains guidelines on constructing and applying a ‘dual crop coefficient’ method to characterize the behavior of evapotranspiration (ET) on a day to day basis. The dual crop coefficient (Kc) method substantially improves the ability to fit simulated with measured data, as compared to the ‘single’ Kc method, by partitioning evaporation from soil (Es) from transpiration from vegetation. This permits the separate estimation of Es when there are known wetting events from precipitation and irrigation and assists in explaining behavior of measured data. The application of the dual Kc method is …

Density Dependent Double Brooding In Piping Plovers (Charadrius Melodus) In The Northern Great Plains, Usa, Kelsi L. Hunt, Lauren R. Dinan, Meryl J. Friedrich, Mary Bomberger Brown, Joel G. Jorgensen, Daniel H. Catlin, James D. Fraser

School of Natural Resources: Faculty Publications

Piping Plovers (Charadrius melodus) are primarily monogamous birds that usually raise only one brood per season, but rare instances of double brooding have been documented. Piping Plovers breeding in the northern Great Plains, USA were studied in two locations: the Missouri River near the Gavins Point Dam (2005- 2013) and the lower Platte River (2008-2013). There were 25 confirmed instances of double brooding on the Missouri River across the 9-year duration of the study. There were no instances of double brooding observed locally on the lower Platte River. However, in 2013, two female Piping Plovers successfully hatched eggs …

Evaluating Recreationists’ Awareness And Attitudes Toward Piping Plovers (Charadrius Melodus) At Lake Mcconaughy, Nebraska, Usa, Joel G. Jorgensen, Mary Bomberger Brown

School of Natural Resources: Faculty Publications

Piping plovers (Charadrius melodus) are shorebirds federally protected by the U.S. Endangered Species Act that often nest on beaches in proximity to human recreation. We evaluated whether awareness of piping plovers and their legally protected status and attitudes toward species management varied between groups of recreationists at Lake McConaughy, Keith County, Nebraska, USA. Awareness of piping plovers varied primarily by the respondents’ number of annual visits to Lake McConaughy; the respondents’ age, sex, or location of primary residence had less influence. Recreationists with increased awareness of piping plovers and their protected status did not have more favorable attitudes toward plovers …

Space Use, Daily Movements, And Roosting Behavior Of Male Wild Turkeys During Spring In Louisiana And Texas, John T. Gross, Andrew R. Little, Bret A. Collier, Michael J. Chamberlain

School of Natural Resources: Faculty Publications

Because wild turkeys (Meleagris gallopavo) are an important game species and turkey hunter numbers are increasing, the need for better information on how turkeys use their environment is critical. With the recent advent of GPS technology suitable for use on wild turkeys, we are now able to collect data on a scale not previously possible. We used backpack style GPS units to detail home range and core area sizes, daily movement distances, and roosting characteristics of male Eastern (M. g. silvestris) and Rio Grande (M. g. intermedia) wild turkeys in Louisiana and Texas. Mean …

Habitat Characteristics Of Eastern Wild Turkey Nest And Ground-Roost Sites In 2 Longleaf Pine Forests, Mary M. Streich, Andrew R. Little, Michael J. Chamberlain, L. Mike Connor, Robert J. Warren

School of Natural Resources: Faculty Publications

Managing and restoring longleaf pine forests throughout the Southeast is a conservation priority. Prescribed fire is an integral part of these activities, as it is the primary means of controlling hardwood encroachment and maintaining native groundcover. Nest site and preflight brood groundroost site selection of eastern wild turkeys (Meleagris gallopavo silvestris) has not been well studied in longleaf pine systems. Therefore, we determined habitat characteristics associated with wild turkey nests and ground-roosts in 2 longleaf pine forests in southwestern Georgia. We radio-tagged 45 female turkeys and evaluated habitat characteristics associated with 84 nests and 51 ground-roosts during the …

Fish-Protection Devices At Unscreened Water Diversions Can Reduce Entrainment: Evidence From Behavioural Laboratory Investigations, Jamilynn B. Poletto, Dennis E. Cocherell, Timothy D. Mussen, Ali Ercan, Hossein Bandeh, M. Levent Kavvas, Joseph J. Cech Jr., Nann A. Fangue

School of Natural Resources: Faculty Publications

Diversion (i.e. extraction) of water from rivers and estuaries can potentially affect native wildlife populations if operation is not carefully managed. For example, open, unmodified water diversions can act as a source of injury or mortality to resident or migratory fishes from entrainment and impingement, and can cause habitat degradation and fragmentation. Fish-protection devices, such as exclusion screens, louvres or sensory deterrents, can physically or behaviourally deter fish from approaching or being entrained into water diversions. However, empirical assessment of their efficacy is often lacking or is investigated only for particular economically or culturally important fishes, such as salmonids. The …

Reviews And Syntheses: Optical Sampling Of The Flux Tower Footprint, John A. Gamon

School of Natural Resources: Faculty Publications

The purpose of this review is to address the reasons and methods for conducting optical remote sensing within the flux tower footprint. Fundamental principles and conclusions gleaned from over 2 decades of proximal remote sensing at flux tower sites are reviewed. The organizing framework used here is the light-use efficiency (LUE) model, both because it is widely used, and because it provides a useful theoretical construct for integrating optical remote sensing with flux measurements. Multiple ways of driving this model, ranging from meteorological measurements to remote sensing, have emerged in recent years, making it a convenient conceptual framework for comparative …

Response Of A Stoichiometrically Imbalanced Ecosystem To Manipulation Of Nutrient Supplies And Ratios, Zarraz M. Lee, Laura Steger, Jessica R. Corman, Marc Neveu, Amisha T. Poret-Peterson, Valeria Souza, James J. Elser

School of Natural Resources: Faculty Publications

Cuatro Ciénegas Basin (CCB) is a desert ecosystem that hosts a large diversity of water bodies. Many surface waters in this basin have imbalanced nitrogen (N) to phosphorus (P) stoichiometry (total N:P > 100 by atoms), where P is likely to be a limiting nutrient. To investigate the effects of nutrient stoichiometry on planktonic and sediment ecosystem components and processes, we conducted a replicated in situ mesocosm experiment in Lagunita, a shallow pond located in the southwest region of the basin. Inorganic N and P were periodically added to mesocosms under three different N:P regimes (P only, N:P = 16 and …

Volcanic eruptions are a widespread force of geological and ecological disturbance and present recurrent opportunities for the study of biological responses to novel habitat formation. However, scientific study of such events is difficult given their short duration and often distant location. Here we report results from opportunistic sampling of unique volcano-generated habitats formed during the 2011 explosive eruption in the Puyehue-Cordón Caulle complex (Chile), when massive amounts of pumice were ejected, creating novel floating substrata that have never before been characterized from a microbiological perspective. DNA sequencing revealed a dynamic community of microbes that came to inhabit the pumice, with …
