The Father Motive: Predicting The Impact Of Father Attitudes On Involvement, Nathan Lovell Robbins

Theses and Dissertations

The purpose of this study was to evaluate the effects that a man's attitudes towards fathering have on the level of involvement with his children. Of particular interest was whether fathering attitudes moderated some of the more consistent predictors of involvement, such as relationship quality, maternal gatekeeping, mother's and father's employment hours, a man's history with his own father, family structure, and child characteristics. A sample of 2300 men was used to evaluate the effects of fathering attitudes on engagement and warmth among children ages 2 to 8 and 9 to 11. Results indicate an inconsistent main effect between fathering …

American Pikas (Ochotona Princeps) Extirpated From The Historic Masonic Mining District Of Eastern California, Lyle B. Nichols, Kelly B. Klingler, Mary M. Peacock

Western North American Naturalist

American pikas (Ochotona princeps) are small alpine lagomorphs and talus obligates with a narrow range of temperature tolerance, along with physiological and ecological characteristics that make them especially vulnerable to local extirpation in the face of climate change. Since their initial colonization of the Great Basin during the Pleistocene geological epoch, the distribution of pikas in this region has become more restricted, with population losses occurring especially in lower-elevation sites characterized by relatively low precipitation and high temperatures. Even where pikas have persisted, many populations are now restricted to higher elevations. We surveyed several sites in the Bodie …

Response In Abert's Squirrel Abundance To Forest Treatments On Camp Navajo, Arizona, R. Nathan Gwinn, Jessica A. Gist, Joel M. Diamond, Hannah Telle

Western North American Naturalist

Abert’s squirrels (Sciurus aberti) are dependent upon ponderosa pine (Pinus ponderosa) forests in northern Arizona. Abert’s squirrels feed primarily on the inner bark of ponderosa pine branches, as well as the tree’s seeds and the hypogenous fungi associated with ponderosa pines. Abert’s squirrels require interlocking tree canopies for escape cover and for feeding, particularly in winter months when snow impedes ground travel and the ability of Abert’s squirrels to access fungi and hoarded food. In the Southwest, land managers in the ponderosa pine belt are implementing large-scale forest restoration treatments to reduce fire risk and return …

Seed Selection By Desert Rodents: Implications For Enhancing Seedling Establishment Of Indian Ricegrass (Achnatherum Hymenoides), William S. Longland, Lindsay A. Dimitri

Western North American Naturalist

Seeds of many plant species are dispersed by seed-caching rodents that place groups of seeds in superficially buried scatterhoard caches. A case in point is Indian ricegrass (Achnatherum hymenoides), an important forage plant on arid western rangelands for which seedling recruitment comes largely from scatterhoards made by desert heteromyid rodents. A “diversionary seeding” strategy has been attempted for enhancing Indian ricegrass seedling recruitment by deploying commercially available seeds on the soil surface to divert rodents from recovering scatterhoards of Indian ricegrass seeds. The probability of such a passive restoration approach succeeding is likely affected by the relative desirability …

Twelve Years Of High-Resolution Near-Surface Radiometer Data Provides Insight Into End-Of-Season Controls In A Dry Grassland, Lynn M. Moore, William K. Lauenroth

Western North American Naturalist

The onset of plant dormancy has proven difficult to explain in nearly all ecosystems. Most research has focused on the end-of-season dynamics of deciduous ecosystems, where leaf coloration and leaf fall are the primary phenological responses. More complex are the end-of-season dynamics of grasslands, where the mechanism of dormancy is a gradual response to climatic variables. These complications are magnified in dry grasslands, where the effects of temperature on phenology are modulated by the availability of soil water. Our objectives were to identify the primary drivers influencing the timing of end of season on the shortgrass steppe and determine if …

Caught Between A Rock And A Hard Mineral Encrustation: Long-Lived Aquatic Insects Accumulate Calcium Carbonate Deposits In A Montane Desert Stream, Eric K. Moody, Jessica R. Corman, Michael T. Bogan

Western North American Naturalist

Aquatic ecosystems overlying regions of limestone bedrock can feature active deposition of calcium carbonate in the form of travertine or tufa. Although most travertine deposits form a cement-like layer on stream substrates, mineral deposits can also form on benthic invertebrates. However, little is known about which taxa may be prone to calcium carbonate encrustation and which life history traits may make taxa more susceptible to becoming encrusted. Here we report the presence of calcium carbonate deposits on live insects collected from a montane stream in the Madrean Sky Islands (Huachuca Mountains) of Arizona between 2011 and 2013. Life history differences …

Intersystem Implications Of The Developmental Origins Of Health And Disease: Advancing Health Promotion In The 21st Century, Michael D. Barnes, Thomas L. Heaton, Michael C. Goates, Justin M. Packer

Faculty Publications

The developmental origins of health and disease (DOHaD) theory and life course theory (LCT) are emerging fields of research that have significant implications for the public health and health promotion professions. Using a DOHaD/LCT perspective, social determinants of health (SDH) take on new critical meaning by which health promotion professionals can implement DOHaD/LCT guided interventions, including recommended policies. Through these interventions, public health could further address the sources of worldwide chronic disease epidemics and reduce such disease rates substantially if related policy, programs, and interdisciplinary and multi-sector collaboration are emphasized. Additional characteristics of the most effective interventions involve context-specific adaptation …

Water Supply System Classification For Water Quality Improvement, Bruno Melo Brentan, Gustavo Meirelles Lima, Edevar Luvizotto Junior, Joaquín Izquierdo, Rafael Pérez-García

International Congress on Environmental Modelling and Software

Universal access to drinkable water is a constitutional right guaranteed in Brazil. However, not all cities in this country are able to supply the population with the expected quality. Important actions should be taken to improve the supply of drinkable water. To define a strategic plan for this purpose, classification tools can facilitate the design of plans, by grouping cities with similar quality conditions. During the last decades, neural network approaches have been used in environmental models, allowing more accurate representation of some complex systems. This work proposes the use of self-organizing maps (SOM’s) coupled with the k-means algorithm …

A Framework For Decision-Making In Cases Of Invasive Species, Peter A. Khaiter, Marina G. Erechtchoukova, Sina Roushan

International Congress on Environmental Modelling and Software

Invasion of nonindigenous species is one of the most pressing global challenges, causing substantial environmental, economic and social harm. Invasion of alien species alters the composition, structure and functioning of invaded ecosystems as well as the services they generated before the invasion. Decisions about the management of invasive cases are inherently difficult because of the multifactorial and multiattribute scope of the problem. In particular, the resilience limits of invaded ecosystems to fully recover original, pre-invaded states remain unclear. To facilitate management efforts, decision-makers and environmental practitioners require a framework integrating relevant knowledge and acting as a supporting expert system. The …

Planning Complex Agro-Ecosystems: The Case Of Analog Forestry, F. Recanati, Giorgio Guariso, M. Saini, Sergio Vilchez Mendoza

International Congress on Environmental Modelling and Software

Traditional agroecosystems, aimed at maximizing the short term productivity, are characterized by oversimplification of ecological structure and dependence on the use of external inputs. Moreover, intensive agriculture is one of the main cause of deforestation. The main consequence of traditional agriculture is the loss of natural ecosystems and of their precious services. Analog forestry has emerged as a sustainable productive model able to be integrated in forest contexts, without degrading their ecological functions. The obtained agro-ecosystem is characterized by an ecological structure similar to the one of forest, and by the presence of several productive species in the same area. …

Big Data In Land Change Science: Challenges And Implications Of Advanced Technologies, Hichem Omrani, Amin Tayyebi

International Congress on Environmental Modelling and Software

Big data has received a lot of attentions during last decade. Dealing with big data is a complex task as it is challenging to analyse, store, model and make sense of big data. Using big data in land change science (LCS) is a new area of research. One of the main challenges in LCS is using big data for model calibration effectively. In this study, we propose using clustering technique, based on k-means approach, to handle big land-use data and overcome the limitation of model calibration. With clustering, data are partitioned into smaller subsets and are t hen analysed …

Multi-Label Classification Methods For Predicting Mixed Land Use Change, Hichem Omrani, Amin Tayyebi, Amir H. Tayyebi, Bryan Pijanowski

International Congress on Environmental Modelling and Software

Current progress on land use highlights the interest of the multi-label concept in predicting land use change. The new concept allows a multi-label class assignment (ML), where a spatial unit may be associated simultaneously with a set of multiple classes. The multi-label concept is different than the commonly used mono-label one (ml: binary or multi-class), in which a spatial unit has only one elementary label at a time. Recently, it has been shown the merit of the ML concept to model mixed land use change. In this paper, we study the multi-label class-assignment by different multi- label classifications models. The …

Analyzing Regime Shifts In Agent-Based Models With Equation-Free Analysis, Romina Martin, Spencer Angus Thomas

International Congress on Environmental Modelling and Software

Conventional tools to analyze regime shifts in ecosystems, e.g. stable state and bifurcation analyses, are increasingly adapted to investigate social-ecological systems. The challenge lies in combining the analysis of system dynamics with the analysis of transient dynamics emerging from adaptive and heterogeneous agents. A typical question is, to which extent do micro level interactions contribute to a macro level outcome? We demonstrate the application of a new tool, equation-free analysis, for evaluating the state space from an agent-based model (ABM) on lake restoration. By sidestepping the requirement of an equation describing a systems macroscopic behavior, equation free analysis enables system …

Chemical Transformation System: Cloud Based Cheminformatic Services To Support Integrated Environmental Modeling, Kurt Wolfe, Nicholas Pope, Rajbir Parmar, Mike Galvin, Caroline Stevens, Eric Weber, Jonathan Flaishans, Tom Purucker

International Congress on Environmental Modelling and Software

Integrated Environmental Modeling (IEM) systems that account for the fate/transport of organics frequently require physicochemical properties as well as transformation products. A myriad of chemical property databases exist but these can be difficult to access and often do not contain the proprietary chemicals that environmental regulators must consider. We are building the Chemical Transformation System (CTS) to facilitate model parameterization and analysis. CTS integrates a number of physicochemical property calculators into the system including EPI Suite, SPARC, TEST and ChemAxon. The calculators are heterogeneous in their scientific methodologies, technology implementations and deployment stacks. CTS also includes a chemical transformation processing …

In Situ Data Visualization Of Acme Land Model Simulations, Yu Pei, Benjamin Hernandez, Dali Wang, Brian Smith, Scott Atchley, Fengming Yuan, Chad Steed

International Congress on Environmental Modelling and Software

With the ever increasing precision and complexity of various environmental models, writing large volumes of [email protected] to disk for post-processing becomes a huge bottleneck, and simulation modules diagnostic and tracking become difficult for scientists as well. In this paper, we propose a loosely coupled in situ visualization framework to address these problems when working with a representative land model within the Accelerated Climate Modeling for Energy (ACME). ACME land model (ALM) simulates energy, water, carbon nitrogen fluxes and state variables for various land surfaces. Loosely coupled in situ framework means simulation and visualization communicate through network, while tightly coupled means …

Location, Identification, And Low Complexity Tracking Algorithms With An Image Compression Strategy For A Long Term Multi-Tracking Application, Ramon Reig-Bolaño, Pere Marti-Puig, Moisès Serra-Serra

International Congress on Environmental Modelling and Software

A biological experiment that requires a continuous tracking of a group of 10 to 20 fish specimens was designed to obtain empirical data to estimate biological energy models from specimen’s activity. The surface in which specimens can move is enormous (2,5m x 5m) in comparison to the sizes of the individuals and it is mandatory to work with high resolution images in order to cover all the area. Furthermore, as each experiment must work uninterruptedly during fifteen days the cost of storing and post-processing all the generated information in its rough form is prohibitive, incurring into a big data problem. …

Group-Based Crop Change Planning: Application Of Smartscapetm Spatial Decision Support System For Resolving Conflicts, Amin Tayyebi, Jamal J. Arsanjani, Amir H. Tayyebi, Hichem Omrani, Hossein S. Moghadam

International Congress on Environmental Modelling and Software

Agricultural changes are complex and managing an appropriate type of crop change to satisfy stakeholders with various interests is challenging. Decisions regarding a crop change need to be debated among multiple stakeholders with various conflicting viewpoints. Two kinds of conflicts might occur as a result of crop change in an agricultural landscape: 1) conflicts among multiple ecosystem services i.e., internal conflicts and 2) conflicts among multiple stakeholders i.e., external conflicts. In this study, we held a series of meetings with stakeholders, who were experts in economics, energy, soil erosion, greenhouse gas emission, surface water, and biodiversity, to develop two crop …
