Twitter News and the Uninformed Citizen
This essay examines how social media as a source of news has severely impacted the political knowledge of the citizens of the United States. Research shows that while the media traditionally has been a moderator that sought to improve knowledge among voters and inspire them to determine their own beliefs, the rise of social media sites such as Facebook and Twitter have inspired a polarizing effect on those who use the platform. Thus, social media is driving both conservatives and liberals away from the middle without providing them the knowledge that they need to have informed opinions. This study sought to determine if the use of social media as a news source caused a negative effect on political knowledge. Respondents were asked to reply to a variety of questions regarding their media consumption and questions aimed at determining two types of political knowledge as defined by authors Michael Delli Carpini and Scott Keeter. Results of the research showed an 8.5% difference in total average questions answered correctly between social media users and other forms of media. Using a cross-tabulation between referred media choice and number of answers correct, the data provided a chi-square value statistically significant at the .05 level. This significant correlation pushed me to the conclusion that of those who use Twitter, those who use it for their primary news source are less politically knowledgeable than those who use other forms of media for their news
Romantic Ken : time and perspective in the poetry of Coleridge and Wordsworth
This dissertation focuses on the connection between representations of time and representations of sight in the poetry of Coleridge and Wordsworth. These poets often use descriptions of their narrators\u27 views as means of marking and measuring time\u27s progress.This study argues that the technique of perspective depiction allows both poets to demonstrate the reconciliation of the philosophical tensions which are imbedded in their poetry.When speaking of Coleridge and Wordsworth, one might generalize about two of their chief concerns as follows. First (and as many critics have observed), the poetry of each of these men reflects an inconsistency regarding the relationship between the external and internal realms. For Wordsworth, this issue is manifested in his ambivalence about the degree of nature\u27s influence (or lack thereof) on the mind. For Coleridge, a similar dilemma appears in his constant wavering between a Hartleian materialism and a Berkeleyan Idealism. Second, it is also generally acknowledged that the art of each poet often seems to alternate between two different conceptions of time: one is objective and successive, and the other is subjective and durational. Throughout the works of both poets, one may recognize the tensions that arise due to frequent dalliances within conflicting epistemological and temporal schemes.Numerous critical studies have considered the issues of perspective and time in this poetry; often, these topics appear in slightly modified form in discussions of landscape and memory, respectively. However, few have touched on the interactive relationship between sight consciousness and time consciousness. This thesis argues that these poets utilize the connection between one\u27s visual field and one\u27s conception of time. Through ingenious narrative presentations of temporal and visual data, each author is sometimes able to mediate between his conflicting philosophical tendencies. Surprisingly, both Coleridge andWordsworth achieve this by grounding their narrators in landscapes that contain particularistic time-space details. One finds that such dense fields of vision allow for the convergence of divergent strains within their epistemological and temporal systems
Defining benefit and hazard: Distribution of Upper and Lower Tertiary units on the northeast flank of the Missoula Valley Montana
Two Tertiary units on the northeast flank of the Missoula Valley are distinct from each other; the lower unit bears resemblance to the middle Eocene to late early Miocene Renova Formation, and the upper unit closely resembles the middle Miocene to Pliocene Sixmile Creek Formation. However, previous studies mapped the two units together or partially dififerentiated the units in an inconsistent manner. Exposures are limited, and strata are difficult to trace on the valley flank. But the units can be mapped separately. Outcrops of conglomerate containing mylonite clasts indicate the depositional environment of the lower Tertiary unit included a river flowing north from an ancestral Bitterroot Valley. Deposits near the southern end of the valley flank indicate the river was flanked by series of coalescing alluvial fans Though similar to the Renova Formation, the lower Tertiary unit is distinct because it contains exotic clasts deposited in a fluvial environment.
I identified two lithologie facies of the upper Tertiary unit A conglomerate facies is in angular unconformable contact with the northeast-dipping lower Tertiary unit This is a fluvial deposit and may be ancestrally related to the Clark Fork River A boulderdominated conglomerate facies of the upper Tertiary unit, coeval with the fluvial deposit, was generated from a broad debris-flow/alluvial fan system which flowed primarily out of an ancestral Grant Creek. A lack of age evidence within the upper Tertiary unit makes its assignment to the Sixmile Creek Formation premature.
The mylonite-bearing, non-lenticular, coarse fluvial deposits of the lower Tertiary unit can transmit significant quantities of water to wells. Based on bedding orientations taken fi-om outcrops, these beds can be targeted in the subsurface.
Landslides on the valley flank result fi’om the interplay of the lower and upper Tertiary units. Interstitial water drains through the coarse upper Tertiary unit and travels along the contact between the upper and lower units. Near the topographic surface, where the water-logged contact intersects with poorly lithified, clayey, ash-rich beds of the lower Tertiary unit, landslide failure may occur if the topography along the contact is sufficiently steep. Overburden fi-om the upper Tertiary unit adds to the driving forces necessary for slippage. A reasonable estimate of landslide potential can be made based on proximity to the geologic contact between the upper and lower Tertiary units.

Common Whitethroats Curruca communis show a continuum of residency duration but a high degree of between-years site fidelity at nonbreeding grounds in Nigeria
Funding: A.P. Leventis Conservation Foundation, Consejo Nacional de Ciencia y TecnologÃa (CONACyT). Grant Number: 472286.The nonbreeding period represents a significant part of an Afro-Palearctic migratory bird's annual cycle. Decisions such as whether to remain at a single site and whether to return to it across years have important effects on aspects such as survival, future breeding success, migratory connectivity, and conservation. During this study, we color-ringed 337 common Whitethroats Curruca communis and undertook daily resightings to understand site persistence and the degree of site fidelity throughout three nonbreeding periods (November-April) in Nigeria. The probability of detecting a color-ringed Whitethroat when it was present was 0.33. Site persistence varied widely across individuals (1-165 days) and did not differ significantly with sex or year, though first-year birds remained for significantly shorter periods than adults. We believe that shorter residencies are likely due to the use of multiple stationary nonbreeding sites rather than low winter survival. A minimum of 19% of individuals returned to the study site the following year and shifted, on average, 300 m, suggesting that Whitethroats have a relatively high degree of between-years site fidelity at a very fine scale. An individual's previous residency duration did not seem to determine its residency duration the following year. We suggest that spatial fidelity is high and constant through years, but temporal fidelity is not, and individual residency patterns vary, probably according to yearly and seasonal conditions. Our results highlight the complexity of the annual cycle of a single species and the importance of carrying out in situ, fine-scale research throughout a migrant's annual cycle over several years.Publisher PDFPeer reviewe

Migratory routes, breeding locations and multiple non-breeding sites of Common Whitethroats Curruca communis revealed by geolocators
This work was supported by the National Council for Science and Technology (CONACyT, Mexico, https://conacyt.mx) through scholarship number 472286 to CTH, and the AP Leventis Conservation Foundation (https://www.leventisfoundation.org/).Understanding general migration characteristics and how breeding and non-breeding sites are connected is crucial for predicting the response of long-distance migratory bird populations to environmental changes. We use data collected from six geolocators to describe migratory routes and identify breeding and non-breeding locations, migratory behaviour and differences between spring and autumn migration of Common Whitethroats Curruca communis, an Afro-Palearctic migrant, wintering in Nigeria. Most individuals departed on spring migration in April, following a north-easterly direction, arriving at their breeding grounds across central-eastern Europe (~425,000 km2) in May. Departures from breeding grounds took place between July and August in a south-westerly direction. During spring migration individuals travelled longer distances at faster rates making its overall duration shorter than autumn migration. We suggest that, while Whitethroats can cross the Sahara Desert and Mediterranean Sea in a single flight, they are likely to refuel before and after crossing. Results indicate that Whitethroats undertook loop migration and visited two wintering sites: first in the Sahel, then in Nigeria, where they remained until spring migration. Geolocator results and data from the European Union for Bird Migration’s (EURING) ringing database suggest that Whitethroats have a relatively high migratory spread—individuals from a single non-breeding site breed across a wide area of Europe. Our research is the first to track and describe the complete annual cycle of Whitethroats and one of the few studies to do so for any Afro-Palearctic migrant from non-breeding grounds. We identified the Sahel as an important refuelling and first wintering site indicating its conservation, alongside other stopover sites, is crucial for the species. We believe that changes in this region will have severe effects on a subset of individuals of specific European breeding populations, but these effects will greatly depend on the severity of the changes and at what spatial scale they occur.Publisher PDFPeer reviewe
