The Relationship Of Equal Division Of Labor And Satisfaction Of Division Of Labor To Positive Parenting As Mediated By Parents' Relationship Quality, Lauren Alyssa Bone Barnes Jul 2010

The Relationship Of Equal Division Of Labor And Satisfaction Of Division Of Labor To Positive Parenting As Mediated By Parents' Relationship Quality, Lauren Alyssa Bone Barnes

Theses and Dissertations

Couples learn to negotiate a complex intersection between household labor and family processes. Using both observational coding and questionnaire self report, this study examined the relationship between father and mothers' reported equality with their division-of-labor, their satisfaction with division-of-labor and their respective positive parenting as observed in taped interaction with a target child while controlling for quality of the relationship between the parents. Findings showed that egalitarian division of labor was positively related to satisfaction in division of labor and that egalitarian division of labor was a significant predictor of mothers' relationship quality, but not fathers' relationship quality. It also …

Chronic Amp-Activated Protein Kinase Activation And A High-Fat Diet Have An Additive Effect On Mitochondria In Rat Skeletal Muscle, Natasha Fillmore

Theses and Dissertations

Factors that stimulate mitochondrial biogenesis in skeletal muscle include AMPK, calcium, and circulating FFAs. Chronic treatment with either AICAR, a chemical activator of AMPK, or increasing circulating FFAs with a high fat diet increases mitochondria in rat skeletal muscle. The purpose of this study was to determine whether the combination of chronic chemical activation of AMPK and high fat feeding would have an additive effect on skeletal muscle mitochondria levels. We treated Wistar male rats with a high fat diet (HF), AICAR injections (AICAR), or a high fat diet and AICAR injections (HF+AICAR) for six weeks. At the end of …

Assessing Traditional Morphology- And Chemistry-Based Species Circumspections In Lichenized Ascomycetes: Character Evolution And Molecular Species Delimitation In Common Western North American Lichens, Steven Leavitt

Theses and Dissertations

Accurate species delimitation has critical implications for ecological and conservation studies; and for understanding factors driving diversification. However, a growing body of evidence indicates that morphology-based species circumspection in lichenized ascomycetes often fails to accurately represent the number of fungal species. The use of molecular data in lichen systematics provides an important alternative to traditional morphological characters for identifying natural groups and assessing evolutionary histories in challenging lichen taxa. In this work, I examined two common lichen-forming genera in western North America, Rhizoplaca and Xanthoparmelia, as models for investigating character evolution, species delimitation in morphologically and chemically diverse species, …

Landscape-Scale And Macrohabitat-Scale Variation In Growth And Survival Of Young June Sucker (Chasmistes Liorus) In Utah Lake, Joshua Daniel Kreitzer

Theses and Dissertations

The spatial scales at which ecological phenomena are viewed constrain the results of interactions between species and their environments. In lake ecosystems, important dynamics have been identified at the landscape scale and the macrohabitat scale. To determine if landscape-scale effects and macrohabitat-scale effects are important in survival and growth of young June suckers, we compared variation among sites in Utah Lake. Large semi-permeable cages were used to house June suckers in situ at five sites representing landscape-scale variation and two sites representing macrohabitat-scale variation in Utah Lake. We compared survival and growth among sites and related it to resource availability …

Modeling And Support Tools For Studying Disease Spread In Livestock Using Networks, Joel Francis, Greg Klotz, Neil Harvey, Deborah Stacey

International Congress on Environmental Modelling and Software

The natural occurrence or intentional release of highly contagious agents of livestock disease can have serious consequences for any country’s agricultural economy. Successful control and management of animal disease outbreaks require that adequate response strategies be developed beforehand. Disease spread simulation models are being used by veterinary epidemiologists to evaluate strategies for the control of disease spread. These models enable decision-makers and emergency preparedness personnel to explore many different scenarios to determine the effects of control measures such as vaccination, and study the likely size, duration and cost of outbreaks. This paper presents an overview of livestock disease spread modeling …

From Landscape-Scale Models Of Forest Biodiversity Change Towards An Integrated Planning Tool – A Gui For Building Empirical Ecological Extrapolation Models Based On Land Cover Data –, Tobias Lung, Gertrud Schaab

International Congress on Environmental Modelling and Software

Spatially explicit models linking biological field data with remotely-sensed landcover data have become commonplace for landscape-scale biodiversity assessments, butthey usually neither consider time series data nor include future scenarios. Extrapolationmodels addressing these deficiencies for three keystone species/groups of the Kakamega-Nandi forests in western Kenya proved to be a suitable means for investigating the effectsof long-term land change processes on the development of forest biodiversity in space andtime. However, the experimental modelling design of the approaches is not consideredconvenient for a more comprehensive, interlinked assessment including morespecies/groups and also ecosystem functions and services, nor is it adequate for a stronglocal stakeholder …

Advances In The Integration Of Watershed And Lake Modeling In The Lake Winnipeg Basin, Luis F. León, William Booty, I. Wong, Craig Mccrimmon, S. J. Melles, G. Benoy, J. Vanrobaeys

International Congress on Environmental Modelling and Software

Estimating non-point source pollution from watersheds and the effects of mitigation measures (e.g. beneficial management practices or BMPs) is an important step in managing and protecting water quality, not only at the basin level where it originates, but also at the receiving waters such as reservoirs, lakes or oceans. Lake Winnipeg is a prime example of such land-lake interactions, where eutrophication and increased algal blooms in the lake are fueled, as evidence suggests, from agricultural sources of nutrients in the region. Over the years, simulation models at the watershed level have been applied to aid in the understanding and management …

Evaluating Climate Suitability For Agriculture In Switzerland, A. Holzkämper, P. Calanca, J. Fuhrer

International Congress on Environmental Modelling and Software

With climate change increased water shortage and extreme weather eventsduring the cropping season may cause more frequent crop loss, yield instability, and makecultivated areas less suitable for traditional crops. In order to develop long-term agriculturalpolicies, planners need to understand the likely impacts of climate change on the climatesuitability for different cultivation types. Agroclimatic indices have great potential tocommunicate the impacts of climate change. However, each metric only represents aspecific aspect of climate that may or may not be relevant for the growth of a certain croptype. To guide planners and policy makers, different indices have to be aggregated in acomprehensible …

Uncertainty Of A Biological Nitrogen And Phosphorus Removal Model, A. Cosenza, G. Mannina, G. Viviani

International Congress on Environmental Modelling and Software

In the last few years, the use of mathematical models in wastewater treatment plant (WWTP) processes has become a common way to predict WWTP behaviour. However, mathematical models generally demand advanced input for their implementation that must be evaluated by an extensive data gathering campaign, which cannot always be carried out. This fact, together with the intrinsic complexity of the model structure, leads to model results that may be very uncertain. Quantification of the uncertainty is imperative. However, despite the importance of uncertainty quantification, only a few studies have been carried out in the wastewater treatment field, and those studies …

Effective Engagement Of Stakeholders In Total Maximum Daily Load Development And Implementation, Erica Gaddis, Carl Adams, Alexey Voinov Jul 2010

Effective Engagement Of Stakeholders In Total Maximum Daily Load Development And Implementation, Erica Gaddis, Carl Adams, Alexey Voinov

International Congress on Environmental Modelling and Software

Total Maximum Daily Loads (TMDLs) identify the maximum amount of pollution that a water body can receive and still support its designated uses and allocates the maximum load to specific sources in the watershed. In the United States, The Clean Water Act requires public participation in the process of TMDL development. This requirement has been met through simple presentation of results at public meetings, strategic partnerships with key stakeholders, and/or to advisory committees in which stakeholders participate in critical decisions about TMDL definition and implementation. These decisions include model selection and assumptions, selection of water quality endpoints, load allocations, TMDL …

Dynamics Of Habitat Banking Under Changing Conservation Costs And Habitat Restoration Time Lags, Martin Drechsler, Florian Hartig Jul 2010

Dynamics Of Habitat Banking Under Changing Conservation Costs And Habitat Restoration Time Lags, Martin Drechsler, Florian Hartig

International Congress on Environmental Modelling and Software

Tradable permits are a popular instrument for environmental policy. Classical examples are emission control, but tradable permit systems are recently also promoted and applied to the conservation of biodiversity. This raises a number of challenges. One problem is that habitat turnover (the destruction of habitats and restoration elsewhere) is harmful to many species, even if the total amount of habitat is constant. Another problem is that the restoration of habitats often takes time, leading to time lags between the beginning of restoration activities and the time when the restored habitat is available for trading. It is therefore important to understand …

A Geosimulation Tool To Assess Intervention Scenarios In Relation To The Spread Of Infectious Disease And Environmental Factors, Mondher Bouden, Bernard Moulin, Pierre Gosselin

International Congress on Environmental Modelling and Software

Several approaches have been proposed to model and simulate the spread ofinfectious diseases such as the West Nile virus (WNV). However, these approaches such asmathematical modeling and cellular automata have some weaknesses when trying to modeland simulate the influence of geographic and climatic features on the disease spread and thespatio-temporal interactions of various kinds of actors (e.g. mosquitoes, birds, mammalsand humans in the WNV case). In this context, we propose to apply a geosimulationapproach to remedy some shortcomings of current methods. Using such an approach wedeveloped WNV-MAGS, a tool allowing public health decision policy makers to assessseveral intervention scenarios in …

Towards Adaptive Control Of Landscape Biodiversity, J. Gary Polhill, Andrew Jarvis, Alessandro Gimona, Nicholas M. Gotts

International Congress on Environmental Modelling and Software

This paper reports work using a coupled agent-based model of land use changeand species metacommunity model (FEARLUS-SPOMM) to explore biodiversity incentivemechanisms using adaptive control algorithms. Existing work at the LancasterEnvironment Centre has shown that such algorithms can help in analysing the adaptivecapabilities of climate-related policy interventions under uncertainty. In particular,feedback control is a practical approach that mimics many recognisable features of adaptivedecision making processes, including the sequential review of models and policies in thelight of new observations. In a companion paper, we show that FEARLUS-SPOMM showsnonlinear dynamics in the relationship between agricultural incentives and biodiversityoutcome. In this pilot study, we …
