THE USES AND GRATIFICATIONS OF MUSIC, BY PERSONALITY TYPE, OF A CENTRAL SOUTH AFRICAN RADIO STATIONâS AUDIENCE

Kotzee, Rozanne 18 July 2013 (has links)
Various methods of communication exist and the understanding of the subtle differences in each form of communication may aid the compassing of this complex process. An example of one such method is music. At any given moment, worldwide, in restaurants, homes, offices, vehicles, night clubs, etc. people are listening to music. Music surrounds us, whether our listening to the radio, being put on-hold during a telephone call or going about day-to-day activities. Music has become a significant part of our lives â a ubiquitous social phenomenon and is the centre of various social activities, like concerts, where people gather to listen to and talk about music. Even in social gatherings where music is not the primary focus, for example weddings, it is an essential component â imagine a wedding without music (Rentfrow and Gosling 2003: 1236-1237). Radio stations may be regarded as some of the largest users of music as a method of communication. Wimmer and Dominick (2006:361) indicate that music is the main product of many radio stations and is of utmost importance for their economic sustainability. Furthermore, the audiences of radio stations â thus the receivers of the communication â also play an important role in the communication process employing music specifically as a method of communication. It may, therefore, be valuable to gain insight into the music preferences of a radio stationâs audience. As music is mostly the main product of a radio station, it is of cardinal importance to be able to identify the music preferred by the audience of that particular radio station. The audience figures for commercial radio stations are directly related to the radio stationâs advertising income (Wimmer and Dominick 2006:361). Despite the prevalence of music in our lives, the study into the personality psychology of music has remained mainly mute. Various questions remain regarding the individual differences and different uses of music, as well as individual differences and music preference choices. It is a given fact that people differ from one another. Precisely how and why they differ is less apparent and forms the focus of personality or individual differences research in the social science and, in particular, psychology (Rentfrow and Gosling 2003). It has been identified that there is currently a lack of knowledge and research specifically related to the relationship between personality traits, the uses and gratifications of music and the music preferences of radio audiences. The aim of this study will be to investigate the possible development of a predictive measurement tool in order to predict the music and genre preference for different psychographic groups of respondents who represent the audience of a central South African radio station, as well as their uses and gratifications of the music. Examining the patterns of music use and the relationship between music use and psychographic profiles, by employing the Ten- Item Personality Inventory (TIPI) and the Uses of Music Inventory (UMI), may contribute to the development of a more efficient model in the construction of a radio stationâs music content and diversity. However, it should be noted that this will, by no means, be an exhaustive study into neither the exact influences on music preference nor the patterns of music use amongst the audience of this radio station.

Paul Tillich's Communication Theology and the Rhetoric of Existentialism

Earle, Elizabeth R. 22 September 2014 (has links)
20th century theologian and philosopher Paul Tillich believed that religion could only be understood in the context of the surrounding culture. He attempted to assert Christianitys importance in the modern era, and did this through his use of language. In this study I examine how Tillichs rhetorical situation uniquely informed the communication style of his sermons. Drawing on the work of Lloyd Bitzer, this rhetorical situation includes Tillichs exigencies, rooted both in the personal and historical, his resources and constraints in the form of influences and limitations, and his audience which provided him with an arena. By examining selections from the three volumes of Tillichs sermons, it is possible to construct his communication theory in five parts. These five elements include logos, or the appropriate use of reason; kairos, or right-timing; language invention and reconfiguration, including translation of religious symbols into existential language; prophetic style; and a focus on community and love. This project is a unique contribution to Tillichian studies and homiletics, as I examine Tillichs sermons within a rhetorical and communicative frame.

The Devil Made Her Do It: Three Horror Film Case Studies in the Exorcism Subgenre

McDonald II, Charles Austin 10 June 2014 (has links)
Although interest in exorcism has spiked in real world and fictional filmic contexts, scholars have yet to fully identify the exorcism film as a subgenre of the horror film. Following Anne Rothes (2011) argument that representation of trauma in popular culture may function like a discursive knot in contemporary culture due to its vast associative powers of generating interactions between disparate ideas (p. 4), this study recognizes exorcism as a discursive knot that deserves further attention. Utilizing a case study approach, this dissertation focuses on three exorcism films: The Exorcism of Emily Rose (2005), The Last Exorcism (2010), and The Conjuring (2013). Results concluded that although filmmakers utilize a distinct formula of narrative stages and signature characters to represent contemporary exorcism, such elements were negotiated through each films construction. Additionally, this study utilizes Lowensteins (2010) concept of spectacle horror to highlight dynamic elements of the exorcism film including: bodily contortions, film-viewer relationships, and intertextuality. Based on the analysis, gender stands as a significant theme in the exorcism films content and in conceptualizing its constitution. Exorcism films portray women as inescapably connected to men, but rebellious performances of possession provide liberatory possibilities for new symbolic orders. This study also indicates that representation of exorcism itself is gendered and draws attention to the distinct strategies characters utilize. Finally, this dissertation finds the mother-daughter relationship as a crucial site of stability (and horror) in the exorcism film.

When We Break Bread Together: Perceptions of Consensus Amongst Queer Organizers

Caswell, David M. 08 May 2014 (has links)
This thesis aims to understand consensus decision making through the experiences of lesbian, gay, bisexual, transgender, and queer (LGBTQ) activists in Louisiana through autoethnography and interviews with various individuals involved in Louisiana LGBTQ organizations. When looking at the experiences and perceptions of the participants in relation to each other and the authors own experiences, the ideas equity, responsibility, and flexibility stand out along with organizational structure. This suggests that consensus may be defined based on these elements. In the narrow scope of this thesis, consensus building in queer spaces in Louisiana can be defined as the opportunity to be in community and to share in power, accountability, and understanding which is created at the intersection between organizational structure and the nature of personal relationships of the actors in that space.

Perceptions of Collegiate and Professional Black Male Athletes Based on the Media

McNeal, Dionell 30 July 2014 (has links)
This study focuses on how media usage can affect ones perceptions of Black collegiate and professional male athletes. While early research focused solely on traditional media, this study focuses on social media as well. This study investigates the relationships between the amounts of time spent using traditional and social media, and the perceptions of athletes in regards to their physical capability, the likelihood of being criminals, and prevalence of committing violent crimes. To explore relationships, this study utilized a total of 145 White participants. Findings showed a positive relationship existed between social media usage and perceptions of criminal-like characteristics. It was found that as social media usage increases, an increase in the perceptions of Black collegiate and professional male athletes having criminal-like characteristics increases as well. Also, results showed that perceptions of criminal-like characteristics, physical prowess, and violent crimes are attributed more to Black athletes than to White athletes. Lastly, findings showed heavy users of traditional and social media attribute more perceptions of criminal-like characteristics than light users of traditional and social media.

Teacher Matters: Teacher Normative Influence and Student Persistence in College

Denham, Jonathan Paul 30 July 2014 (has links)
This dissertation extends the work on teacher immediacy (TI) and student persistence by using the Theory of Planned Behavior (TPB) (Ajzen, 1985) to account for variability in college student persistence. Students provided perceptions of their teachers immediacy behaviors using modified versions of Gorhams (1988) TI scale. Instruction prompts of the TI scale were manipulated to create four conditions. The results from Study 1 demonstrate that TI scale prompt language has an effect on the ways participants assess their teachers immediacy behaviors. The results from Study 2 show that student perceptions of their teachers immediacy behaviors change over the course of an academic semester, such that TI is statistically higher at the end of the semester than at the beginning, as measured by collecting data at four time points. The results from both studies generally support the hypotheses and suggest the TPB accurately predicts college student persistence. However, it is unclear how TI is influencing the overall TPB structural model. In some cases, adding TI to the TPB structural models resulted in a poorer fitting model. Discussions, limitations, and future research are provided for both studies.

Die verband tussen kommunikasievrees van Afrikaanssprekende hoërskoolleerlinge en skolastiese prestasie / Hester Aletta Pretorius

Pretorius, Hester Aletta January 1997 (has links)
This study aimed to provide scientific answers to the following questions: what the nature and extent of communication apprehension are among Afrikaans speaking high-school pupils and the correlation between this fear and the academic achievement of the pupils. In order to provide answers for these questions, human communication as an activity had to be studied in more detail. A study was made of communication and how it is applied in the classroom situation. A very close relationship exists between communication and teaching and it is evident that teaching cannot take place without communication. Teaching is a particular kind of communication which can be distinctly recognised from other forms of communication by the fact that it has the aim of enabling the learner to perform certain learning tasks. Communication apprehension or the lack there of can greatly determine the success of the communication process as well as the teaching-learning process. Communication apprehension was studied in more detail with the aim to establish possible causes and effects of high levels of communication apprehension in pupils. Suggestions were offered for preventing and/or surmounting communication apprehension in the classroom. The following information has been acquired through the use of the PRCA (Personal Report on Communication Apprehension) which was completed by pupils of the four Afrikaans high-schools in Potchefstroom. • 15,9% of the pupils experienced high levels of communication apprehension. • Pupils who take Afrikaans on the standard grade, in each context, experienced the highest levels of communication apprehension. • Pupils whose achievements fall in the interval 0%-49% experienced the highest communication apprehension in each context. • Pupils whose achievements fall in the interval 80% - 100% experienced the lowest communication apprehension in each context. Research on communication apprehension should be broadened to include pupils of primary schools. The causes of high levels of communication apprehension should be examined further, with the aim to establish programmes which could help in reducing communication apprehension of pupils. / Skripsie (MEd (Vakdidaktiek))--PU vir CHO, 1997
