For Love Or Money? The Economic Consequences Of Delayed Marriage, Jason S. Carroll

Faculty Publications

It has been well documented that over the last few decades we have seen a substantial increase in the median age of marriage in the United States. In fact, we are currently at all-time historic highs in these trends. According to the Current Population Survey from the U.S. Census, the median age of marriage right now is nearly 29 years of age for men and 27 years of age for women. Given the trajectory of this trend over the last several years, we are quickly approaching a time in our culture where half of marriages will occur for individuals after …

Effort, Luck, And Voting For Redistribution, Lars J. Lefgren, David P. Sims, Olga B. Stoddard

Faculty Publications

We conduct an experiment to determine how the correspondence between economic rewards and effort, as opposed to luck, affects subjects' ex post voting over redistribution. We find that a large, statistically significant proportion of both high- and low-payoff voters are willing to vote contrary to their self-interest in favor of groups that exert proportionately more effort. We confirm these results in an additional, distinct sample. We also show that when subjects' own effort is greater than the group's average effort level, they exhibit greater self interest in voting for redistribution compared to subjects whose effort is below average. Our results …

No Association Between Latent Toxoplasmosis And Multiple Body Measures In U.S. Adults, Bruce L. Brown, Andrew N. Berrett, Shawn D. Gale, Lance D. Erickson, Dawson W. Hedges

Faculty Publications

Toxoplasma gondii (Nicolle et Manceaux, 1908) is an intracellular parasite that can cause ongoing latent infection persisting for the duration of a non-definitive host's life. Affecting approximately one-third of the world's population, latent toxoplasmosis has been associated with neuropsychological outcomes and a previous report suggested an association between latent toxoplasmosis and adult height. Given the large number of people with latent toxoplasmosis and its potential associations with human height, we sought to better understand the association between latent toxoplasmosis and human morphology by evaluating seropositivity for T. gondii and multiple body measures reported in the National Health and Nutrition Examination …

Solutions For Wellness: Outcome Review And Analysis Of A Healthy Lifestyle Group, Gary Burlingame, Valerie King, Rebecca Janis

Faculty Publications

Individuals with serious mental illness (SMI) experience a notably decreased life span due, in part to a metabolic syndrome linked to psychotropic medications commonly prescribed to SMI patients. Eli Lilly’s Solutions for Wellness (SFW) program was designed to address some of the risk factors (e.g., weight, diet, lifestyle) that exacerbate the metabolic syndrome in SMI outpatients. However, there is limited data as to the effectiveness of the SFW program for hospitalized SMI patients. We replicate and compare SFW outcomes from an inpatient SMI population treated at the Utah State Hospital with previous research that tested an abbreviated SFW curriculum of …

The Unique Influences Of Parental Divorce And Parental Conflict On Emerging Adults In Romantic Relationships, Scott R. Braithwaite, Reed A. Doxey, Krista Dowdle, Frank D. Fincham

Faculty Publications

Parental divorce and parental conflict influence children across multiple domains, including risk of divorce in their own marriages. However, parental conflict and divorce, both separately and the interaction between the two, have not often been studied in premarital relationships, especially when considering possible mechanisms mediating these effects. In a large sample of emerging adults (N = 353), we show that when the most plausible mediating mechanisms are simultaneously considered, only relational commitment mediates the influence of parental conflict on outcomes. Parental conflict in the absence of divorce was associated with less commitment and, in turn, less relationship satisfaction and stability …

An Evaluation Of A Smartphone–Assisted Behavioral Weight Control Intervention For Adolescents: Pilot Study, Chad D. Jensen, Kristina M. Duncombe, Mark A. Lott, Sanita L. Hunsaker, Kara Mcrae Duraccio, Susan J. Woolford

Faculty Publications

Background: The efficacy of adolescent weight control treatments is modest, and effective treatments are costly and are not widely available. Smartphones may be an effective method for delivering critical components of behavioral weight control treatment including behavioral self-monitoring.

Objective: To examine the efficacy and acceptability of a smartphone assisted adolescent behavioral weight control intervention.

Methods: A total of 16 overweight or obese adolescents (mean age=14.29 years, standard deviation=1.12) received 12 weeks of combined treatment that consisted of weekly in-person group behavioral weight control treatment sessions plus smartphone self-monitoring and daily text messaging. Subsequently they received 12 weeks of electronic-only intervention, …

Criteria Language Teachers Use When Selecting Call Technologies, K. James Hartshorn, Benjamin L. Mcmurry, Peter J. Rich, Neil J. Anderson, David D. Williams

Faculty Publications

It is important to identify the criteria that language teachers consider when selecting technologies. Software designers and developers, program administrators, and others need to be aware of adoption issues and practices for CALL technology. The focus of this case study was to look at six language instructors considered to be experts in their use of technology in the classroom and examine the criteria they use when selecting CALL resources or activities in the classroom. Interviews, recorded classroom observations, and analyses of teaching materials resulted in three themes: consideration of pedagogy, consideration of convenience, and consideration of authenticity. These are discussed …

Chronology, Climate, And Fremont Maize Farming In The Great Salt Lake Region, Christopher J. Allison, James R. Allison

Faculty Publications

Archaeologists usually say that Fremont maize farming in the Great Salt Lake region began at about AD 400, and that a mid-1100s drought caused the ancient inhabitants of the region to give up farming. But radiocarbon dates from the region do not support these dates. The earliest dated maize and the earliest dated human skeletal remains with bone chemistry suggesting maize consumption both suggest that maize was not grown in the region until after AD 600. Also, recently obtained dates on maize from Fremont villages indicate that farming in the region continued into the AD 1200s. If the end of …

Excavations At Vista Del Valle, A Viejo Period Site Of The Casas Grandes Cultural Tradition In Chihuahua, Mexico, Michael T. Searcy, Todd Pitezel

Faculty Publications

In the summer of 2015 we conducted excavations at a site located along the Palanganas River, just south of the Casas Grandes River Valley in northwestern Chihuahua, Mexico. This represents the first excavation of a Viejo Period site (A.D. 700–1200) in this vicinity since the 1960s. We discovered remnants of at least five structures, and fully excavated three. This paper reports our findings and compares them to previous work carried out in the region.

Sibling Experiences: Living With Young Persons With Autism Spectrum Disorders, Tina Dyches, Beth Ward, Brianna Smith Tanner, Barbara Mandleco, Donna Freeborn

Faculty Publications

Like other young people, those with autism spectrum disorder (ASD) have an impact on siblings in both positive and negative ways. Research indicates positive attributes include maturity and responsibility; positive self-concept; less quarrelling and competition; admiration for the person with ASD; and satisfactory sibling relationships. Negative attributes include fear of frightening or violent behavior, decreased sibling intimacy, and social and emotional difficulties. However, most research relies on information from parents/teachers, rather than from siblings. Therefore, this qualitative descriptive study explored experiences of 11 brothers and 11 sisters living with a young person with ASD through audiorecorded semi-structured interviews. Analysis revealed …

Powering An Industry: The History Of The Calumet And Hecla Electrical System And The Environmental Consequences Left Behind, Emma M. Zawisza

Dissertations, Master's Theses and Master's Reports

The Calumet and Hecla Copper Mining Company in Houghton County, Michigan, was established in 1865 and closed its doors in 1968. This company was a major contributor in developing secondary copper processing and used these methods to produce copper even when its underground mines were closed. C&H built its own electrical transmission system that could have rivaled many during its time. This allowed the company to have the ability to produce and control its electrical network and expand, but it had major environmental effects. Polychlorinated biphenyl compounds (PCBs), used in transformer oil and other components were produced between about 1930 …

Early Copper Smelting In The Lake Superior Region:A Case Study Of The Isle Royale And Ohio Mining Company, 1846-1852, Adrian Blake

Dissertations, Master's Theses and Master's Reports

The lodes of native copper found in the Lake Superior region presented new opportunities for investors and miners alike. Making these opportunities pay required the unique challenges presented by the region’s remoteness and unique geological formations to be overcome. A primary way in which these newly emerging companies overcame these challenges was through successful vertical integration of the copper refining industries. Smelting came to the region early, but met with little success as the workers first needed to retool their skills and experiences to the demands of the region’s mineral deposits. In 1848 the Isle Royale and Ohio Mining Company …

Investigating The Social Habitat Of Deer Hunters In Michigan, Christopher Henderson

Dissertations, Master's Theses and Master's Reports

State wildlife management agencies are funded primarily by revenue from hunting and angling license sales as well as federal excise taxes on equipment. These agencies are also responsible for managing wildlife populations and providing recreational resources to the public. Declines in hunting participation across much of the United States throughout the last two decades have prompted researchers and wildlife professionals to search for explanations and solutions that will ensure a level of funding for state agencies that allows continued management of wildlife within biological and social carrying capacities, engagement in conservation initiatives, and development of recreational opportunities. Most of the …

Archaeological Investigations And Historical Survey, Fort Wilkins Historic State Park: Keweenaw County, Michigan, Eric T. Pomber

Dissertations, Master's Theses and Master's Reports

Michigan Technological University has been performing archaeological and historical surveys at Fort Wilkins Historic State Park as part of a multi-year contract since 2013 with each year’s work focused on different properties held by the Park. The 2015 field season focused on the 6 acre Copper Harbor Range Lighthouse (20KE33) property immediately west of Fanny Hooe Creek resulting in the identification of eight archaeological features through a combination of pedestrian survey, shovel pit testing, and excavation. Among the features identified are the Astor House (20KE83), an early hotel in the region which was noted in the writings of travelers visiting …

East-West Cultural Differences In Visual Attention Tasks: Identifying Multiple Mechanisms And Developing A Predictive Model, Yin Yin Tan

Dissertations, Master's Theses and Master's Reports

Past research has identified East-West differences in visual attention associated with holistic versus analytic perception and reasoning strategies (Nisbett et al., 2001; Boduroglu et al., 2009). These cross-cultural differences might stem from several different mechanisms, which may include: interference suppression, response inhibition, attention to detail vs. object configuration, stimulus centrality vs. eccentricity, number of visual distractors (e.g., display set size or clutter), and others.

Although research has shown East-West differences, the results sometimes appear inconsistent with each other, or they lack clear predictions from underlying theories. For example, evidence of a preference for cluttered displays (Wang et al., 2012), evidence …

Designing Better Symbols: An Attentional Approach To Match Symbols To Performance Goals, Hannah North

Dissertations, Master's Theses and Master's Reports

Effective displays require symbol sets that are customized to specific tasks and performance goals. In order to create such sets, designers must account for the effects of top-down and bottom-up attention. The current work presents a pair of experiments that examined the effects of salience and cueing in a change detection tasks within the flicker paradigm (Rensink, O’Regan and Clark, 1997). Each trial, participants either received no cue or a cue indicating which symbol would be the target. This cueing manipulation isolated top-down effects to the cued condition. Consistent with previous studies (Orchard, 2012; Steelman, Orchard, Fletcher, Cockshell, Williamson & …

Communication Patterns And Strategies In Software Development Communities Of Practice, Shreya Kumar

Dissertations, Master's Theses and Master's Reports

Some of the greatest challenges in the relatively new field of software development lie in the decidedly old technology of communication between humans. Software projects require sophisticated and varied communication skills because software developers work in a world of incomplete, imperfect information where teams evolve rapidly in response to evolving requirements and changing collaborators. While prescriptive models for software process such as Agile suggest ways of doing, in reality these codified practices must adapt to the complexities of a real workplace. Patterns, rather than rules of behavior within software process are more suitable to the varied and mutable nature of …

Contributions Of Glacier Melting To The Upper Watershed Of The Pita River, Ecuador, Teresa Munoz Martinez

Dissertations, Master's Theses and Master's Reports

Evidence suggests that a changing global climate is accelerating glacial retreat around the world. However, there are not many studies that help to understand the influence of climate change on glaciers in the tropical Andes. In many Andean countries, populations use the water that come from the high altitude mountains, especially mountains that are ice covered. Glacial reduction minimizes water resource availability. This report focuses on better understanding the relationship between glacier meltwater, surface water runoff, and the groundwater flowing into and under the Pita River upper watershed, which crosses the base of the northeast foothills of the Cotopaxi volcano. …

The Utility Of The Participatory Approach For Sustainable Development Assessments, Ashma Vaidya

Dissertations, Master's Theses and Master's Reports

‘Sustainability’ may be a generalizable concept; its definition however, heavily depends upon context. Understanding the context (sociocultural, environmental, socioeconomic, political etc.) is crucial for defining and assessing the sustainability of any given socio-ecological system. This point underlies our research design and objectives. The primary objectives of this research were to understand the sustainability context in the Upper Peninsula of Michigan, and to use it to develop a sustainability assessment framework for a potential forest-based bioenergy industry in the region. We first reviewed top-down and bottom-up sustainability assessment frameworks. Then we used the best-suited approach i.e. bottom-up participatory approach, to pursue …

The Effect Of Community Connectivity On Water And Sanitation Systems In Rural Panama, M.C. Moritz

Dissertations, Master's Theses and Master's Reports

The world has yet to realize universal access to water and sanitation. Various academic and professional fields provide frameworks for understanding water and sanitation access, but none directly consider the impact of community connectivity. Community connectivity refers to the infrastructures linking rural communities with urban centers. These infrastructures fall under the broad categories of transportation, energy, and telecommunication. This paper examines 23 rural Panamanian communities and compares connectivity measures with the functionality of the communities’ rural water and sanitation systems (RWSS). Community connectivity was evaluated with the Community Connectivity Analysis Tool (CCAT), while the water and sanitation systems were evaluated …

Energy Justice And U.S. Energy Policy: Case Study Applications Exploring U.S. Energy Policy Through An Energy Justice Framework, Emily Prehoda

Dissertations, Master's Theses and Master's Reports

This thesis presents three examples of U.S. energy policy and demonstrates how these policies violate the principles of energy justice. First, requiring only Federal agencies to obtain a percentage of energy production from renewables violates the distributive energy justice principle through a lack of a federal renewable energy policy which distributes the potential for unequal electrical grid failure to populations. Second, U.S. energy policy violates the procedural energy justice principle through inequitable participation and poor knowledge dissemination that, in some cases, contributes to stagnant renewable targets during the decision-making process and inequitable distribution of the benefits associated with renewable energy …

Factors Influencing Resilience Among Haematological Cancer Survivors, Katherine S. Gallager

Theses: Doctorates and Masters

Haematological cancers in bone marrow (leukaemia) and the immune system (lymphomas or myeloma) represent the sixth most common adult tumour group in Australia. These cancers often develop without warning and require intensive treatment regimes that last on average eight months, but may continue for a lifetime depending on the diagnosis. Encouragingly, advancing cancer treatments, a key accomplishment of cancer research over the past 40 years, have resulted in a growing community of cancer survivors. Approximately two in three adults diagnosed with haematological cancer (HC) can now expect to survive more than five years. However, they must attempt to navigate the …

Pedagogy In Performance: An Investigation Into Decision Training As A Cognitive Approach To Circus Training, Jonathan Burtt

This research project represents the first formal research conducted into the potential application of Decision Training in an elite circus arts school environment. The research examines the effects of the introduction of Decision Training—a training model developed for sports applications—into the elite circus arts training program at the National Circus School (NCS), a key circus arts school in one of the world’s most vital circus domains, Montreal, Quebec, Canada.

Decision Training, a cognitive-based training model, has been shown through extensive sports-based research to support the development of decision-making ability and self-regulatory learning behaviour, both of which are fundamental for the …

Written Plans And Self-Evaluations In Investigative Interviews With Witnesses, Jane Tudor-Owen

Theses: Doctorates and Masters

The PEACE model of investigative interviewing (Preparation and planning; Engage and explain; Account, clarification, and challenge [Account]; Closure; and Evaluation), has been in operation internationally since the early 1990s when it was introduced in England and Wales. The model is in operation in a number of Australian jurisdictions, including Western Australia (WA), where it was formally incorporated into interview training in 2009. While there have been a number of evaluations of the PEACE model, they have predominantly focused on the interview stages of the model; that is, Engage and explain, Account, and Closure. By comparison, the Preparation and planning and …

Speaking Back To Theory: Community Development Practices In The South West Region Of Western Australia, Colleen Mary Carlon

Theses: Doctorates and Masters

This thesis explores how everyday knowledge of community development practices can inform the theorising of community development in Australia. The literature of community development offers a rich source for understanding and explaining the tensions and dilemmas of collective endeavour in context, yet arguments for particular approaches to community development can serve to evaluate practice in context. In this research, however, case studies are positioned as a source of knowledge. The power of case studies lies in their ability to portray collective action and collective action is what differentiates community development from other approaches to problems. The capacity to work in …

The Experience Of Role Balance Among Australian Working Women With Multigenerational Caring Responsibilities, Kiah Lee Evans

Theses: Doctorates and Masters

Approximately 10% of women in developed countries are working sandwich generation women, who combine paid employment with ongoing multigenerational caring responsibilities for at least one child under 18 years and one parent or parent-in-law. This role combination is expected to become more common due to the increased workforce participation of women, childbirth at an older age, reduced fertility rates, an ageing population and a trend towards community based care. Although there are numerous benefits related to membership in the working sandwich generation, there are also a range of costs related to role participation and quality of life. In particular, these …

Dynamic Risk Management In Fire And Rescue Emergency Operations, Greg Penney

Theses: Doctorates and Masters

Firefighting is an inherently dangerous occupation involving numerous risk sources, unique contexts, multiple personnel and rapidly changing environments. Firefighting operations are dynamic in nature yet require calculated risk taking and structured command to prevent the realisation of potentially catastrophic outcomes to both casualties and rescuers. The notion of “dynamic risk management” is a term that has gained popularity throughout fire services worldwide, yet the process of dynamic risk management is typically poorly articulated. This study demonstrates ‘dynamic risk management’ is a misnomer, with risk management being a defined process applied within the context of dynamic emergency response. Failure to recognise …

Communication: How Do Females With Rett Syndrome Perform This Activity And What Factors Influence Performance?, Anna Urbanowicz

Theses: Doctorates and Masters

Background Rett syndrome is a neurodevelopmental disorder primarily caused by mutations in the X-linked methyl-Cp2G-binding protein 2 (MECP2) gene. The disorder affects approximately 1 in 9000 females and is usually associated with language, physical and intellectual impairments, each of which contributes to difficulties with communication. In Rett syndrome, eye gaze is considered a common form of communication and conventional methods, such as talking and gestures, less common. Females appear to use these forms of communication to serve a number of functions including choice making, requesting, social convention, bringing attention to themselves, and to reject, comment and answer. However, the literature …

Factors Influencing Young Bystanders' Decisions To Intervene When Witnessing Cyber-Aggression: A Mixed Methods Exploration, Lisa Jodi Patterson

Theses: Doctorates and Masters

With the modern proliferation of computers, the Internet and smart phones, adolescents are at increased risk of cyber-aggression: negative, harmful behaviour expressed through electronic means and aimed at an individual (or group of individuals). Cyber-aggression can have serious consequences for the social, emotional and physical health of both targets and perpetrators. Some experts recommend tackling cyberaggression using the strategies applied to face-to-face forms of aggression and bullying in school environments. One such strategy is to encourage peer bystanders to intervene in a positive way, which has been demonstrated to influence both the duration and severity of bullying episodes in the …

Identifying Plant Functional Traits To Assist Ecological Intervention In A Drying Landscape, Ana Luiza Muler

Theses: Doctorates and Masters

Mediterranean-type ecosystems (MTEs) are among the most vulnerable to land use and climate change and many attempts are in place to restore these ecosystems. Therefore, it is necessary to assess differences in plants’ ability to withstand water-stress, including biotic interactions. Such knowledge helps us understand community assembly, which is crucial for ecological intervention. This study involved: (1) reviewing the literature on traits that can differentiate functional types; (2) adapting the methodology to measure leaf water potential at turgor loss point (πtlp) for small-leaved species; (3) using these traits to quickly identify water-use strategies of adult …
