Learning As It Goes Down The Line: Siblings And Family Networked In The Acquisition Of Online Skills, Kylie J. Stevenson, Lelia Green, Leslie Haddon

Research outputs 2014 to 2021

The Parents and Peers project set out to investigate key influences of peers and parents on the online experiences of young people aged 13 - 17. Specifically, the project sought to explore the family constructions of learning, support and management systems that operate in the informal context of the domestic space of the family home (Silverstone & Haddon 1996). It became apparent through interviewing several sets of older siblings that there was benefit in interviewing a wider age range of siblings who were engaged in online activity within individual families. Therefore, the interview participants’ age range was extended to age …

Who Should Bring Home The Bacon? How Deterministic Views Of Gender Constrain Spousal Wage Preferences, Catherin H. Tinsley, Taeya M. Howell, Emily T. Amanatullah

Faculty Publications

Despite the rise of dual-income households in the United States and a narrowing of the nation’s gender wage gap, we find that many men and women still prefer the husband to be the primary breadwinner. To help explain intra-marital wage preferences, we argue for a new construct, gender determinism, which captures the extent to which a person believes gender categories dictate individual characteristics. We show that deterministic views of gender increase both intra-marital wage gap preferences and work choices that may perpetuate the gender wage gap. Our results hold in both student and non-student samples, suggesting some endurance of these …

A Biblical And Missiological Framework For Cross-Cultural Mission: A Case Study Of The Lobi Funeral Rites In Burkina Faso, Boubakar Sanou

Dissertations

Problem

Converts to Christianity in traditional contexts often face pressure to continue traditional rituals and practices which sometimes contain unbiblical elements. Non-selective performance of traditional practices can produce dual allegiance and syncretism. Such is the case with Lobi Seventh-day Adventists concerning their traditional funeral rites of passage. Some core elements of these traditional funeral rites, in which all community members are expected to fully participate, conflict with biblical teachings on the human condition after death.

Method

This dissertation starts by laying the theoretical and theological basis for addressing the problem. The dissertation then uses ethnographic research of funeral rites among …

Effects Of Increasing The Distance Of An External Focus Of Attention On Vertical Jump, Vanessa Frost

Research Papers

Several previous studies have demonstrated the benefits of distancing an external focus resulting in improved performance in a variety of skills. The objective of this study was to investigate whether increasing the distance of an external focus of attention relative to the body improved the performance of the counter-movement vertical jump in recreationally active individuals. It was hypothesized that jumps performed by recreationally active individuals under the external focus conditions would outperform performance completed in the control condition. Moreover, it was also predicted that jump height would systematically increase as the participants focus of attention was directed at an increasing …

A Multiscale Review Of Contemporary Climate Models, Saurav Chakraborty

Research Papers

Atmospheric Oceanic General Circulation Models (AOGCMs) are the primary tools that climate scientists use to investigate past, present and potential future climate. This research paper provides an overview of the strengths and weaknesses of contemporary models across spatial and temporal scales. At large spatial scales, models simulate recognizable patterns of the major modes of climate variability, with a few caveats. Deficiency in reproducing the strength of individual centers of action and detailed temporal characteristics has been noted. The models that best reproduce the spatial pattern are not necessarily the models that simulate the most realistic temporal pattern. Models generally capture …

Evaluation Of 9,10 Anthraquinone Application To Pre-Seed Set Sunflowers For Repelling Blackbirds, Megan D. Niner, George M. Linz, Mark E. Clark

Human–Wildlife Interactions

Most nonlethal methods available for reducing blackbird (Icteridae) damage to sunflowers rely on fright responses (e.g., propane cannons, distress calls, pyrotechnics, raptor silhouettes) that birds quickly learn to ignore. Chemicals that cause taste or feeding aversions have potential to overcome the spatial and behavioral limitations of frightening methods. Anthraquinone (AQ) is an effective feeding repellent as a seed treatment to deter birds from eating freshly planted grains. In the United States, foliar application of AQ is not permitted on food crops except on small experimental plots. In August 2013, we applied 37.4 L/ha of an aqueous mix consisting of 15.1 …

Modeling The Economic Impacts Of Double-Crested Cormorant Damage To A Recreational Fishery, Stephanie A. Shwiff, Katy N. Kirkpatrick, Travis L. Devault, Steven S. Shwiff

Human–Wildlife Interactions

The double-crested cormorant (Phalacrocorax auritus) has undergone a significant range expansion in the Great Lakes area of the United States since the 1970s, negatively impacting native fish populations and sport fisheries. Effective management of wildlife requires policies and practices that quantify their economic impacts, which is often complicated by multiplier effects in the regional economy. This analysis estimates the potential direct and regional economic impacts of the cormorant to a recreational fishery. We estimated that the potential economic loss was on average $5 million to $66 million annually, as well as 66 to 929 job-years in the region …

Human–Felid Conflict In Corridor Habitats: Implications For Tiger And Leopard Conservation In Terai Arc Landscape, India, Manjari Malviya, Krishnamurthy Ramesh

Human–Wildlife Interactions

We use the Rajaji-Corbett corridor in the Terai Arc Landscape (TAL) in India to examine the pattern of human–felid conflict in wildlife corridors and its implications for the long-term persistence of tigers (Panthera tigris) and leopards (Panthera pardus) in the landscape. We administered a questionnaire survey of people residing in and around the corridor and also examined forest department records. Results revealed that leopards caused more frequent losses, whereas tigers caused greater economic losses. Local communities perceived leopards as a bigger threat than tigers, due to the intrusive nature of leopards (i.e., entering villages and houses …

Parallel Universes? Increasing Connections Between Ipm And Wdm, Lynn Braband

Human–Wildlife Interactions

Managing damage by wild vertebrates often is important, and wildlife damage management (WDM) has incorporated important tenets of integrated pest management (IPM). However, largely separate academic backgrounds have nurtured the IPM and WDM communities. The controversial “hot button” topics have tended to differ. While WDM research and outreach have received some IPM funding, and wildlife studies occasionally appear in IPM journals, attendance at infrequent wildlife sessions during IPM meetings has been sparse. The objectives of this paper are to review important examples of collaboration, and evaluate possibilities for future synergy between these related disciplines.

Black Bear Exclusion Fences To Protect Mobile Apiaries, Tammy E. Otto, Gary J. Roloff

Human–Wildlife Interactions

Demand for commercial bee (Apis mellifera) services recently has increased, resulting in greater use of mobile apiaries for crop pollination. When commercial apiaries are moved into areas occupied by black bears (Ursus americanus), conflicts between beekeepers and bears sometimes occur. Commercial pollination often involves moving apiaries among agricultural fields, and, thus, permanent fencing is not a viable option for reducing damage by bears. In 2010, we tested the effectiveness of 4 temporary electric fence designs for excluding black bears from bait sites in northern Michigan. We determined the effectiveness of each fence design by observing bear …

Methodology For Estimating Deer Browsing Impact, Timothy G. Pierson, David S. Decalesta

Human–Wildlife Interactions

Because there were no reliable indicators of deer browsing on tree seedling regeneration, we developed methodology that can be used to measure deer browsing impact. We compared 11 years (2002 to 2012) of annual estimates of deer density with coarse (percent-plots-no-regeneration, percent-plots-no-impact) and fine (3 levels of impact on 6 indicator seedling species) indicators within a 29,642-ha study area in northwestern Pennsylvania. Coarse and fine measures met established criteria for indicators of environmental stress (e.g., high deer density); they were predictive of stresses that can be: avoided by management; integrative with causes of stress; responsive to disturbances and changes over …

The National Wildlife Control Training Program: An Evolution In Wildlife Damage Management Education For Industry Professionals, Paul D. Curtis, Raj Smith, Scott Hygnstrom

Human–Wildlife Interactions

Managing wildlife and reducing damage in rural areas has traditionally been achieved by hunting and trapping problem species or by preventing animals from accessing crops and entering buildings. With urban sprawl, specialized tools and management approaches often are needed to reduce wildlife conflicts in developed landscapes. To address these issues, the private wildlife control industry has grown considerably during the past 2 decades. State wildlife agencies have regulatory authority and oversight of this industry, and there is an increasing trend toward licensing or certification of commercial wildlife control operators (WCOs). Regulations differ in every state, however, and no consistent standard …

Modeling Waterfowl Damage To Crops Surrounding The Quill Lakes In Saskatchewan, Carolyn J. Callaghan, Bahram Daneshfar, Donald J. Thompson

Human–Wildlife Interactions

Waterfowl using the Central Flyway congregate on staging lakes before fall migration. The Quill lakes area of Saskatchewan Province, Canada, contains many staging lakes, which are surrounded by annual cropland. Crop losses to waterfowl occur every year, but the severity fluctuates greatly from year to year. We obtained historical crop compensation data, waterfowl-staging surveys, harvest chronology, and weather records from various agencies. Using GIS, we referenced all data types to potential claim-land parcels (0.65 km² for the damage model and 5 km² for the density model). We constructed empirical landscape level logistic regression models, weighting factors influencing the …

Relationship Between Spatial Distribution Of Sika Deer–Train Collisions And Sika Deer Movement In Japan, Akinao Soga, Shin-Ichiro Hamasaki, Noriko Yokoyama, Toshiyuki Sakai, Koichi Kaji

Human–Wildlife Interactions

Collisions between trains and sika deer (Cervus nippon) cause various problems involving animal and humans safety, as well as economic cost. A better understanding of deer crossing railway lines and deer–train accidents is necessary to develop effective mitigation measures. We investigated the collisions among habitat selection, railway-line crossing movement, and deer–train collisions. We predicted that the risk of deer–train collisions would increase with increasing probability of deer crossing railway lines, which is related to habitat selection surrounding in those areas. Deer stayed in forests to rest during the day and moved to grasslands or rice paddy fields to …

Evaluating Competing Preferences Of Hunters And Landowners For Management Of Deer Populations, Gino J. D'Angelo, Marrett D. Grund

Human–Wildlife Interactions

Most state wildlife agencies consider public input in the management of whitetailed deer (Odocoileus virginianus) populations. In 2013, we surveyed deer hunters (n = 3,600) and landowners (n = 4,604) in southwest Minnesota to gauge their preferences for managing deer. We hypothesized a priori that, irrespective of their perceived impacts of deer, hunters would prefer deer populations to be increased and landowners would prefer deer populations to be decreased. Our findings suggest that defining stakeholder groups according to primary associations with deer (i.e., farming and hunting) accurately categorized differences in tolerance levels for deer populations in …

Administering GonaconTm To White-Tailed Deer Via Hand-Injection Versus Syringe-Dart, Charles S. Evans, Anthony J. Denicola, John D. Eisemann, Robert J. Warren

Human–Wildlife Interactions

Immunocontraceptive vaccines have shown some promise for fertility control of white-tailed deer (Odocoileus virginianus) in urban and suburban habitats where traditional methods of population control may not be applicable. Currently, the only contraceptive vaccine approved by the U.S. Environmental Protection Agency for use in white-tailed deer is GonaCon^TM Immunocontraceptive Vaccine, but it is registered for use via hand-injection only. It has been suggested that remote-delivery of immunocontraceptives would be more cost-effective than hand-injection, but there is the potential for incomplete injection from a syringe-dart. Therefore, the purpose of our research was to: (1) conduct a dart configuration …

Bioaccumulation Of Mercury In Wilson’S Snipe From Alabama, Lindsay J. Brooks, Joshua W. Campbell, Julia W. Murphy

Human–Wildlife Interactions

Mercury is a persistent, toxic heavy metal that can bioaccumulate in organisms, causing diseases and other health problems. Wilson’s snipe (Gallinago delicata) feed primarily on aquatic invertebrates, which makes them prone to mercury bioaccumulation. In this study, we measured total mercury in Wilson’s snipe. Total mercury was measured in the feathers and muscle tissue. Mean concentration (ppm ± SE) of mercury was 1.33 (± 0.22) and 0.087 (± 0.03) in the feathers and muscle tissue, respectively. Mercury concentration was significantly higher in feathers than muscle. Our data indicate that Wilson’s snipe, an aquatic-invertebrate predator that bioaccumulates mercury from …

Does Body Condition Affect Immediate Post-Capture Survival Of Ungulates?, Louis C. Bender

Human–Wildlife Interactions

Many factors are known or are thought to increase vulnerability to capture-related mortality in ungulates. I compared body condition of Rocky Mountain elk (Cervus elaphus nelson), mule deer (Odocoileus hemionus), and pronghorn (Antilocapra americana) to assess whether those that survived capture differed from those that did not. Fate of ungulates was generally not related to condition (F_1,646 = 1.6; P = 0.21), and this relationship was similar among species (species × fate interaction: F_4,646 = 1.3; P = 0.29), season of capture (species × season × fate interaction: F_6,646 = …

Spatial And Temporal Analysis Of Factors Associated With Urban Deer–Vehicle Collisions, Erin C. Mccance, Richard K. Baydack, David J. Walker, Derek N. Leask

Human–Wildlife Interactions

Increasing populations of white-tailed deer (Odocoileus virginianus) in urban areas have resulted in an increase in deer–vehicle collisions (DVCs). Deer–vehicle collisions represent a human–wildlife conflict of serious concern, given that they result, most notably, in significant risk to human safety, deer mortality, and costly vehicle damage. Although many communities have developed databases that track the frequency and location of DVCs, there is a need for analysis of the factors that affect DVC locations in urban areas. Data on deer movement patterns across roads in urban areas are valuable to reduce the occurrence of DVCs on existing roads and …

Quantitative Assessment Of Bullet Fragments In Viscera Of Sheep Carcasses As Surrogates For White-Tailed Deer, Luis Cruz-Martinez, Marrett D. Grund, Patrick T. Redig

Human–Wildlife Interactions

Avian scavengers, such as bald eagles (Haliaeetus leucocephalus), can be exposed to lead through the consumption of spent lead from ammunition in carcasses of animals shot with lead-based projectiles. Few studies have examined the degree of bullet fragmentation in viscera (offal) of game mammals. Our objective was to quantify the number of bullet fragments deposited in sheep carcasses shot with different types of lead and lead-free, high-velocity centerfire rifle bullets and with lead projectiles fired from shotguns and muzzleloader rifles marketed for hunting white-tailed deer (Odocoileus virginianus). We hypothesized that after controlling for velocity, angle of …

Characterization Of The Trans-Plasma Membrane Electron Transport System In The Myelin Membrane, Afshan Sohail

Theses and Dissertations (Comprehensive)

Myelination is the key feature of evolution in the nervous system of vertebrates. Myelin is the protrusion of glial cells. More specifically, "oligodendrocytes" in the central nervous system (CNS), and "Schwann" cells in the peripheral nervous system (PNS) form myelin membranes. Myelin remarkably, enhances the propagation of nerve impulses. However, myelin restricts the access of extracellular metabolites to the axons. A pathology called "demyelination" is associated with myelin. The myelin sheath is not only an insulator, but it is itself metabolically active. In this study it is hypothesized that the ratio of NAD(P)⁺/NAD(P)H and the glycolytic pathway of …

Understanding The Physiological Effects Of Suspended Material On Rainbow Trout (Oncorhynchus Mykiss), Tyler J. Weinhardt

Theses and Dissertations (Comprehensive)

The effect of global warming on northern environments is becoming increasingly evident. Melting of underlying permafrost is associated with widespread impacts in these environments. The loss of permafrost results in a destabilizing of underlying sedimentary layers resulting in thermokarst slumping. When this occurs on a large scale (mega-slumping) soil material becomes mobilized and is carried into local streams and rivers. The purpose of this study is to examine the sub-lethal physiological effects that suspended material has on rainbow trout (Oncorhynchus mykiss) in the context of the Peel River Plateau. Juvenile rainbow trout were exposed (following Environment Canada exposure …

The Effects Of Lampricide 3-Trifluoromethyl-4-Nitrophenol Toxicity On The Gills Of Larval Sea Lamprey And Non-Target Rainbow Trout And Lake Sturgeon, Lisa A. Sorensen

Theses and Dissertations (Comprehensive)

The pesticide, 3-trifluoromethyl-4-nitrophenol (TFM), is widely used in the Great Lakes to control invasive sea lampreys (Petromyzon marinus) populations, but much about its sub-lethal effects remains unknown. A better understanding of its toxicity is needed to improve TFM effectiveness and to protect non-target organisms from its potential adverse effects. The objectives of this thesis were to test the following two hypotheses: (1) impairment of mitochondrial ATP production by TFM interferes with ATP-dependent ion-uptake by fish, leading to altered electrolyte balance, and (2) perturbations of gill function by TFM are exacerbated in soft, ion poor water (SW; 40 mg …

‘Water Is Life’: Exploring The Relationship Between Place Identity, Water And Adaptive Capacity In Fort Resolution, Northwest Territories, Canada, Jennifer A. Fresque-Baxter

Theses and Dissertations (Comprehensive)

Water is recognised as a fundamental human right in Canada’s Northwest Territories (NWT). However, the current and potential effects of climate change coupled with resource development pressures are leading to concerns about maintaining the health and viability of freshwater in the NWT. These intersecting multiple exposures can have far-reaching impacts for NWT residents who rely on water for cultural, spiritual, economic and social purposes. Ongoing changes (e.g., to water quantity, water quality, weather, precipitation and ice dynamics, for example) will increasingly require NWT residents to adapt, seek ways to plan for the future, identify opportunities, and moderate the effects of …

"It's A Very Silent Pain": A Phenomenological Study Of Women Who Are In A Relationship With A Sexually Addicted Spouse, Jacqueline S. Thibodeau

Theses and Dissertations (Comprehensive)

Being in a relationship with someone who is sexually addicted has been recognized as disorienting and painful. What is lacking in the literature is inclusion of the voices of those individuals who have been affected by his behaviour. This study attempts to capture the phenomenon experienced by those individuals who are in a relationship with a person who is sexually addicted. Twelve women, who identified being in a current or past relationship with a person who is sexually addicted, participated in qualitative interviews where they were encouraged to share their experiences. The interviews were analyzed within the transcendental phenomenological framework. …

Connecting To Others: Studying The Relationship Between Social Exclusion And Imitation, Sarah K. Blyth

Theses and Dissertations (Comprehensive)

Automatic imitation (AI) refers to the subconscious tendency we have to imitate an observed action, even when that action is irrelevant to or interferes with an action we are attempting to execute (Heyes, 2011; Brass et al., 2000). Human beings display a fundamental need to stay meaningfully connected to others, also known as the need to belong. Previous research shows that an experience of rejection can reduce one’s feelings of connectedness to others (Legate et al., 2013), and that behaviours such as non-conscious mimicry (NCM) increase after being excluded as a possible means of re-affiliation (Lakin et al., 2008). It …

Pushing The Limits: International Land Acquisitions In Comparative Perspective, Ariane Goetz

Theses and Dissertations (Comprehensive)

The role of investor countries in large-scale land acquisitions is poorly understood in the contemporary “land grab” literature. Orthodox explanations largely build on deductive analyses that deviate from the emerging empirical evidence, and/or face analytical difficulties when trying to capture why large-scale land acquisitions happen. This thesis investigates the global phenomenon of “land grabbing” from the comparative perspective of two major investor countries: the UK and China. The regional focus is on Sub-Saharan Africa, a major target of land-consuming investments since 2000.

The dissertation advances three arguments: Firstly, the specific details of the home country’s industrial set-up, development challenges, ideological …
