  1. Mandated Wage Increases and Gift-Exchange in Labor Markets

    Spurlino, Eric
    Using an experimental methodology, I examine the productivity effects of increases in wages due to an externally imposed mandate in comparison to wage increases due to the generosity of the employer. This paper also introduces a new experimental framework for exploring the concept of gift-exchange in labor markets using groups of participants acting as employers and employees on a real effort task. We find that there is a significant effect of wages on effort levels. In addition, we find that when wages are increased due to an external mandate—all else equal—workers increase their effort levels by less than if their...

  2. Presentations of Terrorism in U.S. News Media

    Filicky, Travis
    The framing and presentation of news stories has been shown to influence audience attitudes and perceptions. With this in mind, this experiment analyzed whether the different terms used to describe the terrorist group ISIS may influence audience attitudes about the religion of Islam. It was thought that terrorism labels could impact Americans’ attitudes toward religious groups, presidential approval, and national security policies. In this experiment, students (N = 440) were exposed to one of three news releases. Two news releases were written to recognize the anniversary of a fictional terrorist attack, whereas the third served as a control and discussed...

  3. Carbon-14 Plant Evidence of mid-Holocene Quelccaya Ice Cap Margin Fluctuations

    Stahl, Henry
    The North Lake Lobe of the Quelccaya Ice Cap in southern Peru represents a wholly unique location for reconstructing paleoclimate conditions. At this location, plant samples were preserved in-situ beneath the advancing glacial ice, and since 2004 have been collected as the ice retreats. The ages of the collected samples were obtained through radiocarbon dating methods. Samples were collected at the surface and at depth. The fine-grained nature of the matrix surrounding the preserved buried samples indicates that several flood events occurred at these sites between ~6,630 cal yr BP and ~6450 cal yr BP due to the ice damming...

  4. Measurements of intrinsic magnetism in multilayer graphene using cantilever magnetometry

    Melendez, Alex L.
    Due to the exponential rate at which technology is progressing, we find ourselves searching for novel nanomaterials at an ever increasing rate as the physical limits of our existing materials are being reached. One such exciting substance is graphene, famous for its extreme electronic characteristics. However one of the many steps necessary in bringing graphene into mainstream technology is the measurement of its intrinsic magnetism. In this thesis we obtain sensitive measurements of the magnetic susceptibility of multilayer graphene using the method of cantilever torque magnetometry, wherein torque exerted on a cantilever is measured from graphene's intrinsic magnetism in the...

  5. Varying Visual Imagery Perspective to Assess Interest

    Carlisle, Clare
    People's personal interests shape significant facets of their lives, but pre-existing beliefs (e.g. "Men are better at math than women") may prevent personal interest development that aligns with actual experiences (e.g. a girl who finds doing math engaging; Chatard et al., 2007). We attempt to address this problem by manipulating visual imagery perspective to attune people to their actual experiences of interest and reduce the impact of pre-existing beliefs. Because first-person imagery invokes a processing style that facilitates bottom-up interpretations, whereas third-person imagery invokes a processing style that facilitates top-down interpretations (Libby & Eibach, 2011), we predicted that first-person imagery...

  6. Psychological Impact of Closed Head Injury

    Blackfield, Danielle
    Closed head injury is a type of Traumatic Brain Injury that has the potential to disrupt normal brain functioning. Studies show that many who experience head injuries, such as concussions, are at risk of heightened depression and anxiety, of suffering from sleep irregularities and personality changes, as well as deficits in cognitive functioning. The purpose of this study is to help better understand the range of symptoms that occur as a result of closed head injuries among a community sample of college students, and to explore the nature of the relations between concussions and these psychological dimensions. One study using...

  7. Understanding cross-regional variation in the effect of remittances on development outcomes

    Kick, Hayley
    It is well-established in the literature that money being sent home by family members and relatives living away from home, i.e. remittances, can help combat poverty and contribute to economic development across the developing world. There is also consensus that remittances to households in low-income countries are growing rapidly and have even outpaced official aid. However, there is still much to be said about why remittances play a larger role in development for certain countries or regions than others. This project explores why there appears to be large cross-regional variation in the impacts of remittances on development outcomes. I begin...

  8. National Revolution and International Interference: How American Intervention Influences Revolutionary States

    Twinem, Joe
    As states across the Middle East have undergone revolutions since 1979, The United States has acted to ensure outcomes that protect and further their economic, military, and political interests. The product of this interference is often further destabilization and political upheaval of the target state. The purpose of this study is to look at revolutions, and near-revolution to see what impact American intervention and aid has had on the outbreak of revolution, and if the history of American intervention shows that it has a significant impact on the success or failure of revolutions. This project analyzes 4 cases of revolution...

  10. Opinions on the Internet: Social Influence and Political Decision Making Processes on Social Media

    MacDonald, Tyler
    Much scholarship has been produced to explain how one’s social identity affects political attitudes and behaviors (Phillips and Carsey, 2013). The majority of this scholarship has focused on heuristics and the party identification model to explain how people form political identities and make political decisions (Scholz and Pinney, 1995; Carmines and Huckfeldt, 1996, Mondak, 1993; Greene, 1999; Iyengar, Sood and Lelkes, 2012). But this scholarship fails to recognize that as society begins to interact more digitally through social media, acquisition of information becomes a social activity (Baek et al., 2012). This study focuses on the impact of social influence on...

  11. Social learning in Neolamprologus pulcher

    Pope, Abigail
    Animals can receive new information via social learning, and acquisition of social information in a changing environment can bestow benefits to an observer by reducing the costs of acquiring information. Many species live in hierarchal social groups in which individuals vary in status. Status may influence learning because dominant individuals are more noticeable and likely more successful at obtaining resources. However, it may also be more pertinent for an observer to obtain information from a similar ranked individual. Little is known about how social status influences learning, thus I performed an experiment to determine how the social status of a...

  12. After the Spill: Environmental Justice and Disaster Relief in West Virginia

    Turley, Bethani
    Using interviews with local activists, survivors of the flood, and environmental professionals, I look at narratives of environmental justice and disaster relief as response to industrial and environmental disasters in West Virginia, focusing on the 2014 Elk River chemical spill and the 2016 floods.

  13. Analyzing the Kantian Amphiboly for the Animals

    Riggleman, Mark
    One of the major abiding challenges for Immanuel Kant’s moral theory has been its apparent inability to account for our duties to animals. Even many Kantians have accepted that if Kant cannot adequately account for such duties, it would be a major black mark for his theory. Kant argues that our duties to animals, those without rational nature, can be only indirect. By, “indirect” he means that duties to animals are a consequence of our direct duties to human beings who have rational natures. The duty in question here is that of improving our moral character. Many argue that common...

  14. Labor Union Locals, Radical Politics, and Sympathetic Views of Social Movement Organizations

    Knipe, Kevin
    Although there are thorough bodies of literature which focus on the different organizational structures of social movement organizations and how organizations cooperate with one another, the American Labor Movement is frequently seen as homologous. While challenged frequently in sociological literature, treating labor unions as interchangeable ignores the various motivations held by union locals. As members of national unions, it is assumed that labor union locals naturally have similar levels of participation both in internal campaigns and in their participation with other national social movement organizations. Operating on this assumption, the study conducted for this article surveyed locals from the Service...

  15. The Languages of Music and Emotion in Joyce, Schoenberg, Cage and Beckett

    Cummins, Alison
    Writers of the modern and postmodern period experimented with new modes of narration and form, often borrowing from musical structures to inform their work. Two such authors are James Joyce and Samuel Beckett, who, in their works, mirror musical innovations made by Arnold Schoenberg and John Cage, respectively. Joyce and Beckett use the formal techniques of music in their literary works to arrive at an improved mode of communication.

  16. Strawberries, Milkweed, Stone

    Williams, Roberta
    This collection of semi-autobiographical poems explores the soul of a Midwestern woman growing up in a world in which Donald Trump could become her President.

  17. A System of Paychecks and Balances: Consequences of Socioeconomic Status on Crime and Fear of Arrest

    Israel, Hallie
    This research study aims to examine the relationship between subjective socioeconomic status (SES) rankings of undergraduate students at Ohio State and participation in alcohol-related crimes, as well as perceived fear of arrest for those crimes. This topic is important to study because it can help us to understand if there are significant variations in alcohol related criminal activity between individuals of different classes, and if an individual’s class status is correlated with their apprehension that they may be arrested for their crimes. Understanding how class affects alcohol-related crimes (and crime in general) can help law enforcement to prosecute these crimes...

  18. Latest Cenozoic foraminifera from the 154-0 m interval of the DVDP 8, 9, and 10 drillholes, Taylor Valley, Antarctica

    McCarren, Heather Kristen
    Benthic foraminifera have been examined from the upper 154 meters of a 186 m thick Pliocene-Holocene glacial succession recovered in the DVDP 8, 9, and 10 drillholes of eastern Taylor Valley, Transantarctic Mountains, Antarctica. The principal objectives of the investigation center on resolving the stratigraphic position of the Pliocene-Pleistocene boundary, establishing the full extent of the Pleistocene succession, and evaluating the potential value of these sediments for refining latest Cenozoic chronostratigraphy. The upper 154 meters of the succession were subdivided into twenty-four lithostratigraphic subunits by McKelvey (1981). Subunits are expressions of discrete lithofacies packages such as diamictite, conglomerate, breccia, sands, and mudstone. A well-defined disconfonnity at a drillhole depth...

  19. Origin of zeolites from the Kirkpatrick basalt, Solo Nunatak, Antarctica: significance to the petrogenesis of basalt

    Mason, Scott E.
    The Kirkpatrick Basalt has an anomalously high initial 87Sr/86Sr ratio which varies from 0.709 to 0.714. One possible cause for the Sr isotopic anomaly is the alteration of the basalt by the solutions which precipitated zeolites in the vesicles of the basalt. In this study, zeolites from the Kirkpatrick Basalt of Solo Nunatak, North Victoria Land, Antarctica, were found to have identical initial 87Sr/86Sr ratios (0.7100 to 0.7105) as the Kirkpatrick Basalt flows in which they occurred. Therefore, the zeolites formed soon after crystallization of the basalt with Sr derived from the basalt. Because the Sr of the zeolite-forming solutions was derived from the basalt, the Sr isotopic composition of the...

  20. Isotopic investigation of an aragonite marble Orcas Island, Washington

    Endres, Robert A.
    The carbonate fraction of an aragonite marble (20% aragonite, 80% calcite) from the Orcas Formation, Washington has an 87Sr/86Sr ratio = 0.70779 ± 0.00028. This is concordant with the ratio for Early to Middle Triassic sea water and thus could imply a Triassic age, consistent with fossil evidence. The 87Sr/86Sr ratio for the non-carbonate residue of the sample is 0.7123 ± 0.0007 and indicates that Sr homogenization during mid-Cretaceous metamorphism (250°C, 2.5 kB) may not have occurred, allowing the calculation of a Devonian age for the clay fraction. The strontium concentration of the carbonate (614 ppm) is consistent with the conclusion by Vance, (1975) that the aragonite is...
