Cognitive and Auditory Factors Underlying Auditory Spatial Attention in Younger and Older AdultsSingh, Gurjit 09 June 2011 (has links)
Listening to speech with competing speech in the background is challenging and becomes harder with age. Three experiments examined the auditory and cognitive aspects of auditory spatial attention in conditions in which the location of the target was uncertain. In all experiments, word identification was measured for target sentences presented with two competitor sentences. On each trial, the three sentences were presented with one from each of three spatially separated loudspeakers. A priori cues specified the location and identity callsign of the target. In Experiments I and II, sentences were also presented in conditions of simulated spatial separation achieved with the precedence effect. Participants were younger and older adults with normal hearing sensitivity below 4 kHz. For both age groups, the contributions of richer acoustic cues (those present when there was real spatial separation, but absent when there was simulated spatial separation) were most pronounced when the target occurred at “unlikely” spatial listening locations, suggesting that both age groups benefit similarly from richer acoustical cues. In Experiment II, the effect of time between the callsign cue and target word on word identification was investigated. Four timing conditions were tested: the original sentences (which contained about 300 ms of filler speech between the callsign cue and the onset of the target words), or modified sentences with silent pauses of 0, 150, or 300 ms replacing the filler speech. For targets presented from unlikely locations, word identification was better for all listeners when there was more time between the callsign cue and key words, suggesting that time is needed to switch spatial attention. In Experiment III, the effects of single and multiple switches of attention were investigated. The key finding was that, whereas both age groups performed similarly in conditions requiring a single switch of attention, the performance of older, but not younger listeners, was reduced when multiple switches of spatial attention were required. This finding suggests that difficulties disengaging attention may contribute to the listening difficulties of older adults. In conclusion, cognitive and auditory factors contributing to auditory spatial attention appear to operate similarly for all listeners in relatively simple situations, and age-related differences are observed in more complex situations.

Ideographic usage of "choice" in contemporary abortion rhetoricSnider, Sarah Jane January 1900 (has links)
Master of Arts / Department of Speech Communication, Theater, and Dance / Timothy R. Steffensmeier / This work explores the emergence and evolution of the rhetoric choice rhetoric as it pertains to contemporary American abortion politics. <Choice> is explored from an ideographic perspective, borrowing from the theoretical framework for ideographic rhetorical criticism established by Michael Calvin McGee. The analysis begins with a diachronic analysis of the emergence of the ideograph of <choice> within the law with an investigation of the written decisions in four Supreme Court cases central to the construction of the right to choose: Roe v. Wade (1973), Maher v. Roe (1977), Harris v. McRae (1980), and Webster v. Reproductive Health Services (1989). This investigation reveals a synchronic relationship between <choice> and another higher order ideograph, <liberty>. The criticism continues with an investigation of the usage of <choice> by pro-choice advocates in two documents published by NARAL Pro-Choice America, Choices: Women Speak About Abortion is a collection of women's narratives about their experiences obtaining an abortion, and Breaking Barriers, a guide for the development and implementation of proactive policy campaigns for pro-choice advocates. McGee's method is employed to investigate the ideographic usage of <choice> within these documents, revealing the ideographic abstraction that associates the alleged idea content of ideographs. This ideographic analysis reveals the inability of <choice> to live up to its alleged idea content as a result of the limitations inherent in the grounding of <choice> within the higher order ideograph of <liberty> and the impact of these limitations on particular populations, mainly indigent women in the United States.

A stakeholder perspective of corporate social responsibilityOtis, Esther January 1900 (has links)
Master of Arts / Department of Communication Studies, Theatre, and Dance / Nicole M. Laster / The adoption of a corporate social responsibility (CSR) policy affords a company with the opportunity to engage with stakeholders in a manner that is not necessarily tied directly to a company’s business as usual. CSR research has burgeoned in the last several decades, keeping pace with companies worldwide and their steady incorporation of CSR policies into their business models. To that end, research has been primarily focused on CSR policy perception from external stakeholders or managers. This research project examines the sensemaking processes related to an environmental sustainability-related CSR policy among a diverse group of internal stakeholders at a mid-sized electric utility company. An analysis of the data suggests that hierarchical divisions of employees are non-existent when the CSR policy is enduring, consistent, and upholds company values. Moreover, employee enactment of CSR policies operates as a mechanism whereby employees internalize the promoted corporate values. Such environmental CSR policies tacitly reinforce an organization’s cultural values among its employees. Additionally, environmentally sustainable CSR policies supported by environmentally exhausting companies induce a minimal justification hypothesis when dissonance is present between the nature of a company’s industry and practices related to sustaining the environment.

Policy or politics: a content analysis of how the network nightly news covered the 2009-2010 health care issueWinter, LeAnn January 1900 (has links)
Master of Arts / Department of Communication Studies / William Schenck-Hamlin / Many critics and scholars (e.g. Lippman, 1927, Putnam, 2000, Entman, 1989, McChesney, 2004, Funigiello, 2005), have argued that news media coverage of major political affairs and policy often fails to provided citizens with the information they need to engage in these issues in a thoughtful manner. The style of news utilized by networks as well as choices in framing have been found to have a significant impact on what is covered and how audiences perceive coverage (Bennett, 2005, Patterson, 2000, Prior, 2003, Zaller, 2003, Cappella & Jamieson, 1997, Ibrahim, 2010, ‘T Riet et al., 2009, Bizer & Petty, 2005, Ben-Porath & Shaker, 2010, Domke & Shah, 1995, and Esposito, 1996). According to the PEW Foundation (2010) a large portion of the 2009-2010 healthcare coverage focused on politics and not how the healthcare system functions (policy).
This paper explores the coverage of the 2009-2010 heath care issue by the Network Nightly News through the use of a content analysis. For the purpose of this study, the proposed method of Budge et al. (2001) political party platform categories were used to code the content of the broadcast. These 46 codes contained issues that dealt with the policy of health care and the politics surrounding healthcare, as well as positive vs. negative framing. 30 broadcasts were randomly chosen, one day for each month, from the three nightly news networks during the ten months of highest coverage. Each broadcast was divided into “quasi-sentences”, where each sentence was broken down into individual actions. Results illustrate the frequency between policy and political content, and positive and negative content surrounding the 2009-2010 health care issue.
KEYWORDS: Framing, Policy, Politics, Health Care Reform, Network Nightly News, Content Analysis, Quasi-Sentence

A physiological sensor network supported by an inductive communication linkHoskins, Seth January 1900 (has links)
Master of Science / Department of Electrical and Computer Engineering / Steven Warren / The continuous and autonomous real-time monitoring of cattle state of health can provide major benefits for the U.S. livestock industry and lead to a higher quality beef product. Complete real-time monitoring could not only lead to earlier detection of disease in individual animals and reduce the spread of disease to a larger herd, but it could ultimately reduce the cost and frequency of on-site veterinary consultations.
This thesis details a wearable device that is mounted on cattle to collect data from a network of internal and external sensors. In addition to the basic data collection, this thesis will describe the infrastructure to communicate these data sets to a central database for permanent storage and future analysis. Physiological, ambient environment, and physical activity data are acquired by the various sensors to give a good indication of the state of health of an animal wearing the device.
The communication of data from internal sensors to an external wearable receiver is of particular interest since tissue is not an ideal medium for radio-frequency data transmission. Past research has attempted to use such links with little success due to large signal attenuation at high frequencies and a package that becomes much too large to be usable at low frequencies. As a result, a wireless communications method employing magnetic inductance at relatively low frequencies over short distances is described here.

The effects of social media on the body satisfaction of adolescent and young adult femalesWallis, Julia January 1900 (has links)
Master of Science / Department of Apparel, Textiles, and Interior Design / Joy Kozar / The thin female body-type perpetuated in the media has historically caused decreased body satisfaction in adolescent and young adult females (Dittmar, 2009). Previous studies have examined the impact of these images in traditional media, but few studies have examined images seen in social media. Therefore, this study examined how social media impacts the body satisfaction of adolescent and young adult females through the variables of age, time spent on social media, social comparison behaviors, and appearance-related attitudes. The study utilized a sample of females between the ages of 14 to 25. As a component of this study, age was broken into two groups, creating a younger (14-18) and older (19-25) group. This allowed the researcher to make comparisons between the two age groups in relation to the variables being studied.
An online questionnaire was utilized as part of this study and distributed to college professors, high school instructors, high school and college-age students, and via social media platforms such as Facebook, Instagram, and Twitter. A total of 357 female respondents between the ages of 14 and 25 years old participated in the study. Of the 357 participants, 140 (39.2%) were in the age category of 14-18 and 217 (60.8%) were in the age category of 19-25.
Results indicated that participants who accessed their social media accounts more times per day were more likely to engage in social comparison behavior to fashion models and celebrities and peers. In addition, the more participants compared themselves with fashion models and celebrities and peers, the higher their appearance-related attitudes, which lowered their body satisfaction. Age was not a significant factor in predicting time spent on social media, participation in social comparison behavior, or appearance-related attitudes. However, among the sample, younger participants were overall more satisfied with their body than older participants. It was determined that on average, participants checked their social media accounts between 5 and 15 times a day and spent three or less hours daily on social media.
These findings have important implications for the fashion and cosmetics industries and AT educators. The results indicate that social media has an impact on young women’s body satisfaction.

Interactive technologies on art museum websitesKomarova, Maria January 1900 (has links)
Master of Science / Department of Communications Studies / Gregory Paul / This report investigates how American art museums have adopted interactive technologies on their websites. The use of such technologies brings to the forefront a tension regarding authority over visitors’ experience of and interpretation of art both in person and online. Interactive tools on 15 art museum websites were coded as enabling one of three types of interaction: human-to-computer, human-to-human and human-to-content. Human-to-computer interactive features were most prevalent on museum websites, followed by human-to-human and human-to-content interactive technologies respectively. The findings demonstrate a tension between the goals of art museums in wanting to engage visitors in co-creation of meaning about art on the one hand and wanting to maintain their traditional authority over that meaning on the other. The report concludes by offering recommendations for how museums can use interactive technologies more effectively in order to maintain their role as centers of social and cultural life.

The ableist Othering of disability in the classroom: an experiential investigation of academic adjustments in higher educationReutlinger, Corey Jon January 1900 (has links)
Master of Arts / Department of Communications Studies / Timothy Steffensmeier / Due to a rising interest for degrees in higher education, more students with disabilities have enrolled in the university system. Still, accessibility issues on campuses suggest institutions are not meeting the needs of students in the classroom or through curricula. This study examines current academic adjustments and the lived experiences of students with disabilities in order to understand the ableist Othering phenomenon in higher education. Qualitative research methods have been commonly used to investigate the “disabled voice”; however, triangulation of such methodologies has been criticized for reinforcing Otherness. This study used a phenomenological design implementing rhetorical agency for disabled students to answer open-ended questions in semi-structured interviews about their lived experiences. Consequently, such interviews created a platform for social change. The author also reflects on his own lived experiences as a deaf student in higher education. Findings include major themes such as a percolation of institutional hegemony, a re-appropriation of stigma through “voice,” and a call for inclusive strategies. Results indicate disabled students experience discrimination likely due to organizational tension in their university institution. Further, this study elaborates on proposed policy changes to college classrooms on large university campuses. Contributions of this study lie in implications for the future of qualitative inquiry, including how current research practices could undergo methodological reinvention to examine the ableist Othering phenomenon.

Altering perceptions of child sexual abuse survivors and individuals with dissociative identity disorderNorval, Sara Marie January 1900 (has links)
Master of Arts / Department of Communications Studies / Sarah E. Riforgiate / At 47 years old, Lori is a high-functioning businesswoman, matriarch, and contributing member of society. Lori is also diagnosed with Dissociative Identity Disorder (DID). From age 3, Lori was violently raped and assaulted by several perpetrators, yet views her multiple personalities as strength, as survival mechanisms, and wants to share her story to help prevent child sexual abuse. Utilizing methods drawn from communication studies, ethnodrama, and autoethnography, this study aims to tell a person’s story in her own words and in a format that can easily be shared with both academic and non-academic audiences. Lori’s story is woven together as an ethnodramatic play that includes original interview transcripts along with an autoethnographic monologue describing the experience of writing someone’s truth when it challenges the hegemonic views of society, and instead embraces the feminist ideals of equality and deconstruction of power. Academic research needs to reach further than academic journals to make a true impact. Through the non-conventional venues of autoethnography and ethnodrama, we can breathe life into our research and provide accessibility to innovative information for those who may need it most.

How the Buddhist concept of Right Speech would be applied towards diplomatic actions using the media: a case study from the 2002 State of the UnionStout, Daniel R. January 1900 (has links)
Master of Arts / Department of Communication Studies, Theatre, and Dance / Leann M. Brazeal / Communication between countries is an essential part of international relations. Leaders use the media to build confidence, advance negotiations or garner political support. This process is identified as media diplomacy. Television is an important part of international relations, and some have even gone so far to say that ambassadors between countries serve nothing more than a social function. In this analysis it is argued that current strategies of media diplomacy do lead to violence because they encourage power plays, violence, and overemphasis on national ego. The proposed alternative is to embrace a Buddhist alternative identified as Right Speech to overcome current deficiencies. The study found that President Bush’s 2002 State of the Union violated the tenets of Right Speech. The implications of violations including the increased likelihood of violence between nation states will be discussed.
