Distributive Leadership’S Relationship To Teacher Self-Efficacy: An Ecological Model, Mary Dawson Jacques

All Theses And Dissertations

This ecological study identifies and tests research based constructs of distributive leadership and teacher self-efficacy on the 2012 and 2014 TELL survey using ecological methodology. This includes a confirmatory factor analysis of survey items that best measure distributive leadership and teacher self-efficacy. The overall population mean for participants who agreed or strongly agreed with the survey items was calculated and analyzed. The research focuses on a microsystem analysis, but includes a reflection on the exosystem and an analysis of variance with the macrosystem.

Analyses revealed three major findings. First by calculating the overall population mean of participants who agreed or …

Information In The Ecosystem: Against The “Information Ecosystem”, Timothy B. Norris, Todd Suomela

Copyright, Fair Use, Scholarly Communication, etc.

The “information ecosystem” metaphor is widely used in academic libraries and has become nearly ubiquitous when speaking of the information systems that support scholarly communication and varied forms of data sharing and publication. The trending use of this language arises from non-academic applications — for example in big data (the Hadoop ecosystem) or software development (the node.js ecosystem) — and there remains little critical examination of the use of this metaphor. Indeed, the definition of ecosystem as the set of relations between living organisms and their surrounding non-living environment is apparently not directly a part of the metaphor. This paper …

The Increase In Domestic Violence In Brazil From 2009-2014, Nadia Christina Rodrigues, Gisele O'Dwyer, Monica Kramer Andrade, Matthew B. Flynn, Denise Leite Maia Monteiro, Valeria Teresa Saraiva Lino

Political Science & International Studies: Faculty Publications

In recent decades, the rise violent phenomena in Brazil has reached epidemic proportions. However, the prevalence of domestic violence (DV) across different states in the country is not well established. The objective of this study was to describe the distribution of DV across Brazilian states from 2009 to 2014. An ecological study based on spatial analysis techniques was performed using Brazilian states as geographical units of analysis. A multilevel Poisson model was used to explain the risk of DV in Brazil according to age, sex, period (fixed effects), the Human Developing Index, and the victim’s residence state (random effects). The …

Spatial Soundscape Ecology: Application In A Paleotropical Rainforest, Jack Vanschaik

The Journal of Purdue Undergraduate Research

The world’s biodiversity is declining with much of the decrease attributed to human activity. The paleotropical rainforests of Borneo contribute 10% of the world biodiversity but are at risk of destruction due to logging and other human interests. Soundscape ecology, defi ned as the study of the composition of sounds in an environment, is a new fi eld that offers solutions for assessing biodiversity and disturbance. Spatial dynamics are an important component of an ecosystem, yet the link between spatial dynamics and soundscapes has not yet been studied. It should be possible to assess disturbance of an ecosystem by analyzing …

The Mecoptera Of Michigan, Albert R. Thornhill, James B. Johnson

The Great Lakes Entomologist

(excerpt) To date, no one has published on the Mecoptera of Michigan. A comprehensive taxonomic paper on the Mecoptera of Illinois, by Donald W. Webb, Illinois Natural History Survey, and Norman D. Penny, University of Kansas, is in preparation and will include keys to and descriptions of the midwestern species of Mecoptera. It is hoped that the present paper will supplement the publication by Webb and Penny and enable interested persons in Michigan to easily identify adult Mecoptera.

Approaches For Advancing Scientific Understanding Of Macrosystems, Ofir Levy, Becky A. Ball, Ben Bond-Lamberty, Kendra S. Cheruvelil, Andrew O. Finley, Noah R. Lottig, Surangi W. Punyasena, Jingfeng Xiao, Jizhong Zhou, Lauren B. Buckley, Christopher T. Filstrup, Tim H. Keitt, James R. Kellner, Alan K. Knapp, Andrew D.

All Materials

The emergence of macrosystems ecology (MSE), which focuses on regional- to continental-scale ecological patterns and processes, builds upon a history of long-term and broad-scale studies in ecology. Scientists face the difficulty of integrating the many elements that make up macrosystems, which consist of hierarchical processes at interacting spatial and temporal scales. Researchers must also identify the most relevant scales and variables to be considered, the required data resources, and the appropriate study design to provide the proper inferences. The large volumes of multi-thematic data often associated with macrosystem studies typically require validation, standardization, and assimilation. Finally, analytical approaches need to …

The Morphology And Histology Of New Sex Pheremone Glands In Male Scorpionflies, Panorpa And Brachypanorpa (Mecoptera: Panorpidae And Panorpodidae), Albert R. Thornhill

The Great Lakes Entomologist

The n~orphology and histology of a previously undescribed sex pheromone gland in male scorpionflies of the genus Panorpa (Mecoptera: Panorpidae) and a morphologically similar gland in Brachypanorpa (Mecoptera: Panorpodidae) are described and discussed. The gland and the associated pheromone dispersing structure consist of an eversible pouch that lies in the ventral part of the male genital bulb at the point where the basistyles diverge. The glandular layer of epithelium is composed of three types of cells that vary in size between species of Panorpa and between Panorpa and Brachyponorpa. It is suggested that the gland may have evolved from …

Stability, Development, And Function Of A Symbiotic Bacterial Community Associated With The Reproductive System Of The Hawaiian Bobtail Squid, Euprymna Scolopes, Allison H. Kerwin

Doctoral Dissertations

Many aquatic organisms deposit their eggs into an environment where successful embryogenesis depends on minimizing biofouling. The female Hawaiian bobtail squid, Euprymna scolopes, harbors a diverse bacterial community within the accessory nidamental gland (ANG), a symbiotic reproductive organ. This community is hypothesized to be environmentally transmitted, and to be deposited from the ANG into the egg jelly coat (JC). Illumina sequencing of the 16S rRNA V4 gene region demonstrated that the ANG bacterial community (n=29) and that of the JC (n=35) were composed primarily of members of the Rhodobacteraceae and Verrucomicrobia, which together comprised on average 86% of …

Examination Of Multidimensional Acculturation Theory And Acculturation Process On Latinas/Os In Communal Recovery Homes, Roberto Lopez Tamayo

College of Science and Health Theses and Dissertations

Disparities in access and utilization of substance abuse treatment (SAT) among Latinas/os, accentuated by the rapid growth of this population are creating a public health issue. Among those in need of SAT, only 7.7% receive treatment and nearly half of these individuals complete SAT or continue their recovery in a controlled environment. Additionally, Latinas/os who complete SAT reported their needs were not met in treatment. Although substance abuse literature has given more consideration to environmental factors and social support in relation to treatment outcomes, current substance abuse models fail to address important contextual and cultural aspects for Latinas/os in recovery. …

Rethinking Urban Green Infrastructure As A Means To Promote Avian Conservation, Allen Lau

Master's Projects and Capstones

There is an under-recognized potential for cities to use urban green infrastructure to contribute to avian biodiversity conservation. At the global scale, climate change and growing urbanization are primary global drivers leading to decline and homogenization in world bird populations. Birds are fundamental and intricate species in ecosystems, and even in urban areas, act as indicator and regulator species contributing to healthy ecosystem function. While many cities have recognized the economic and social benefits associated with green spaces, such as the vast benefits ecosystem services provide to the urban dweller, the use of green spaces to concurrently contribute to avian …

Advancing Our Understanding Of The Edwardsiella, Stephen Ralph Reichley

Theses and Dissertations

Diseases caused by Edwardsiella spp. are responsible for significant losses in wild and cultured fishes around the world. Historically, Edwardsiella tarda has been considered the most phenotypically and genotypically heterogeneous member of the genus. Investigations into intraspecific variability of E. tarda demonstrated isolates previously classified as E. tarda actually represent three genetically distinct yet phenotypically ambiguous groups, leading to the adoption of E. piscicida and E. anguillarum as discrete taxa. Current genomic investigations have demonstrated significant differences between these organisms. To this end, real-time quantitative PCR assays were developed to quickly and accurately detect the pathogens in pond water, fish …

A Dynamic Landsat Derived Normalized Difference Vegetation Index (Ndvi) Product For The Conterminous United States, Nathaniel P. Robinson, Brady W. Allred, Matthew O. Jones, Alvaro Moreno, John S. Kimball, David E. Naugle, Tyler A. Erickson, Andrew D. Richardson

Numerical Terradynamic Simulation Group Publications

Satellite derived vegetation indices (VIs) are broadly used in ecological research, ecosystem modeling, and land surface monitoring. The Normalized Difference Vegetation Index (NDVI), perhaps the most utilized VI, has countless applications across ecology, forestry, agriculture, wildlife, biodiversity, and other disciplines. Calculating satellite derived NDVI is not always straight-forward, however, as satellite remote sensing datasets are inherently noisy due to cloud and atmospheric contamination, data processing failures, and instrument malfunction. Readily available NDVI products that account for these complexities are generally at coarse resolution; high resolution NDVI datasets are not conveniently accessible and developing them often presents numerous technical and methodological …

Colonizing Opportunistic Pathogens (Cops): The Beasts In All Of Us., Lance B Price, Bruce A Hungate, Benjamin J Koch, Gregg S Davis, Cindy M Liu

Environmental and Occupational Health Faculty Publications

Colonizing opportunistic pathogens (COPs) are microbes that asymptomatically colonize the human body and, when the conditions are right, can cause infections. Their ability to persist indefinitely and to be transmitted without detection [1] gives COPs a unique epidemiology that warrants special consideration. There are examples of COPs among bacteria, fungi (e.g., Candida albicans [2]), protozoa (e.g., Blastocystis [3, 4]), and viruses (e.g., Rhinovirus [5]), but bacterial COPs are of particular relevance because of their major contribution to today’s antibiotic resistance crisis. The COPs include a long list of notorious bacteria that …

Bridging Post-Wildfire Communication Gaps Between Managers, Researchers, And Local Communities, Including A Biological Soil Crust Case Study, Hilary Louise Whitcomb

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Immediately after a wildfire land managers act quickly to protect water supplies, soil stability, habitat, and forage. We don't currently understand how managers make trade-off decisions between social, political, and ecological factors in these tight timelines or if they are able to use new science. We do know ecosystems often benefit from local engagement, and new, scientifically-grounded methods that improve restoration efforts are needed. As post-wildfire timelines don’t often allow for outside input, I asked managers what they and stakeholders think about post-wildfire projects and what managers think about new science. I asked local citizens what they think about postwildfire …

Repeated Evolution Of Vertebrate Pollination Syndromes In A Recently Diverged Andean Plant Clade, Laura P. Lagomarsino, Elisabeth J. Forrestel, Nathan Muchhala, Charles C. Davis

Faculty Publications

© 2017 The Author(s). Evolution © 2017 The Society for the Study of Evolution. Although specialized interactions, including those involving plants and their pollinators, are often invoked to explain high species diversity, they are rarely explored at macroevolutionary scales. We investigate the dynamic evolution of hummingbird and bat pollination syndromes in the centropogonid clade (Lobelioideae: Campanulaceae), an Andean-centered group of ∼550 angiosperm species. We demonstrate that flowers hypothesized to be adapted to different pollinators based on flower color fall into distinct regions of morphospace, and this is validated by morphology of species with known pollinators. This supports the existence of …

Economic Growth And Mortality: Do Social Protection Policies Matter?, Usama Bilal, Richard Cooper, Francis Abreu, Claudia Nau, Manuel Franco, Thomas A. Glass

Faculty Publications

Background: In the 20th century, periods of macroeconomic growth have been associated with increases in population mortality. Factors that cause or mitigate this association are not well understood. Evidence suggests that social policy may buffer the deleterious impact of economic growth. We sought to explore associations between changing unemployment (as a proxy for economic change) and trends in mortality over 30 years in the context of varying social protection expenditures. Methods: We model change in all-cause mortality in 21 OECD (Organization for Economic Cooperation and Development) countries from 1980 to 2010. Data from the Comparative Welfare States Data Set and …

Population Density, Distribution, Richness & Health Of Shallow Water Caribbean Porifera From An Unesco Biosphere Reserve, St. John, Usvi, Patrick Michael Vojnyk

Theses, Dissertations and Culminating Projects

Porifera is an important phylum of organisms in benthic ecosystems that filter water, act as biogenic habitat, and provide 3-dimentional structure. Sponge diversity and abundance are often used as bio-indicators for good or improving water quality in a system. Transects were performed during July 2015, January 2016, and July 2016 to determine species richness, density, and assess necrotic pinacoderm tissue decay of species of poriferans in St. John, USVI. 6,800 individuals and 17 different species were recorded during observation periods in Great and Little Lameshur Bays. Results indicate that the non-cryptic species Amphimedon compressa and Aplysina fiulva had the highest …

Dietary Analysis Of The Emerald Shiner (Notropis Atherinoides) In The Upper Niagara River Using Fatty Acids, Stomach Contents, And Stable Isotopes, Colleen Kolb

Great Lakes Center Masters Theses

Describing ontogenetic and temporal shifts in diet is a fundamental step in understanding food web structure in any ecological community. I conducted a dietary analysis of the emerald shiner (Notropis atherinoides), a keystone species in the Niagara River (NY), using a detailed analysis of fatty acids combined with data on stomach contents and stable isotopes. For both 2014 and 2015, oleic acid and DHA were important fatty acids responsible for the majority of the differences among groups. There was a seasonal shift in fatty acids from relatively high levels of 22:5n-6 and DHA early in the season to …

Using Stable Isotope Geochemistry To Determine Changing Paleohydrology And Diagenetic Alteration In The Late Cretaceous Kaiparowits Formation, Ut Usa, Daigo Yamamura

Graduate Theses and Dissertations

The Western Interior Basin of the North America preserves one of the best sedimentary and paleontological records of the Cretaceous in the world. The Upper Cretaceous Kaiparowits Formation is a rapidly deposited fluvial sequence and preserves one of the most complete terrestrial fossil record of the North America. Such a unique deposit provides an opportunity to investigate the interaction between the physical environment and ecology. In an effort to decipher such interaction, stable isotope composition of cements in sedimentary rocks, concretions and vertebrate fossils were analyzed.

Despite the difference in facies and sedimentary architecture, the isotope composition does not change …

Second section discusses the results of an empirical study on the economics of subsistence fishers in Digha-Shankarpur in Eastern India. Results of the empirical study shows by-catch by the trawlers leads to the depletion of target fish stock of the subsistence fishers. Underutilization of the capacity by the subsistence fishers due to …

Landscape-Scale Manipulation Of The Acoustic Environment Alters The Distribution Of Breeding Birds And Arthropods, Elizeth Cinto-Mejia

Boise State University Theses and Dissertations

Oil and gas development has rapidly increased across the world over the last several decades. Anthropogenic noise, an invisible pollutant that alters animal distribution and behavior, could be responsible for documented wildlife population declines near loud compressor stations in energy extraction fields. We experimentally played back compressor noise, creating a “phantom natural gas field” in a large-scale experiment, and tested the effects of noise on songbird distributions during the breeding season and on arthropod distributions. Further, to begin to understand the influence of noise produced by different types of extraction infrastructure, we examined the effects of sound intensity and bandwidth, …

Summer Habitat Use By A Mammal Community Of An Oak-Dominated Ecosystem In The Central Hardwood Region, Brent Steven Pease

Theses

In the greater Central Hardwood Region, advance regeneration of oak (Quercus spp.) and hickory (Carya spp.) has been in decline for several decades. Facilitated in part by an abrupt change in disturbance regime, coupled with an increase in herbivore density, the existing mid-successional, mast-producing species are being outcompeted by late-successional, mesophytic species. Oak-hickory forests provide keystone resources for a diverse forest wildlife community, and a decline in its dominance will likely impact habitat use and occupancy patterns in the mammal community, but to what extent is unclear. During May-August 2015-2016, I deployed 150 remotely-triggered camera traps in Trail of Tears …

Diversity For Diversity's Sake? The Relationship Between Diversity And School-Level Academic Achievement., Richard Aaron Wisman

Electronic Theses and Dissertations

There is contention among researchers about how to best operationalize socioeconomic status (SES). This study seeks to provide an explicit definition of one metric of socioeconomic status, the diversity index (DI) of Jefferson County Public Schools (JCPS) and investigates its efficacy at predicting the aggregate academic achievement of students within a school, relative to other common metrics of SES which are analogous to components of the DI. Another purpose of this study is to investigate possible peer effects of socioeconomic diversity on low SES students. This study utilizes a correlational – multiple regression approach to explore relationships among study variables …

Effects Of Wave Action On The Structure Of Fish Assemblages Across An Exposure Gradient, Lauren Liddon

Master's Theses

Disturbance affects the function and diversity of ecosystems. Increased wave exposure to salt marsh can disturb sediments and cause a loss of habitat. The purpose of this study was to explore the effects of increased wave exposure on diversity, abundance, and functional ecology of estuarine fishes. If increased wave exposure is acting as a disturbance to these habitats, ecological theory (Intermediate Disturbance Hypothesis) predicts that diversity will peak at intermediate frequencies and intensities of disturbance. Fish were sampled from 10 sites monthly for 6 years. The sites were assigned to different exposure categories (Open, Intermediate, and Sheltered) using an exposure …

Natural And Anthropogenic Effects On Life History Characteristics In The Side-Blotched Lizard (Uta Stansburiana), Geoffrey David Stuart Smith

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Survival is a prerequisite for successful reproduction, and is thus intertwined with fitness. Some physiological systems can improve survival, like the immune system, but compete with other processes for resources. Because animals evolved with resource limitation, it is important to understand how these resource-allocation decisions are made. To meet this end, I performed four investigations addressing how life-history characteristics shift in side-blotched lizards (Uta stansburiana) using laboratory studies and multi-year field sampling. First, I measured metabolic rates in response to different immune challenges and different energy states in male lizards. I found that, surprisingly, cutaneous biopsies were associated …

A Comparison Of Five Statistical Methods For Predicting Stream Temperature Across Stream Networks, Maike F. Holthuijzen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The health of freshwater aquatic systems, particularly stream networks, is mainly influenced by water temperature, which controls biological processes and influences species distributions and aquatic biodiversity. Thermal regimes of rivers are likely to change in the future, due to climate change and other anthropogenic impacts, and our ability to predict stream temperatures will be critical in understanding distribution shifts of aquatic biota. Spatial statistical network models take into account spatial relationships but have drawbacks, including high computation times and data pre-processing requirements. Machine learning techniques and generalized additive models (GAM) are promising alternatives to the SSN model. Two machine learning …

Large-Scale Differences In Microbial Biodiversity Discovery Between 16s Amplicon And Shotgun Sequencing, Michael Tessler, Johannes S. Neumann, Ebrahim Afshinnekoo, Michael Pineda, Rebecca Hersch, Luiz Felipe M. Velgo, Bianca T. Segovia, Fabio A. Lansac-Toha, Michael Lemke, Rob Desalle, Christopher E. Mason, Mercer R. Brugler

Publications and Research

Modern metagenomic environmental DNA studies are almost completely reliant on next-generation sequencing, making evaluations of these methods critical. We compare two next-generation sequencing techniques – amplicon and shotgun – on water samples across four of Brazil’s major river floodplain systems (Amazon, Araguaia, Paraná, and Pantanal). Less than 50% of phyla identified via amplicon sequencing were recovered from shotgun sequencing, clearly challenging the dogma that mid-depth shotgun recovers more diversity than amplicon-based approaches. Amplicon sequencing also revealed ~27% more families. Overall the amplicon data were more robust across both biodiversity and community ecology analyses at different taxonomic scales. Our work doubles …
