Distracted generation (?) : technology use, texting and driving in South AfricaKgasago, Tshepho Justice January 2017 (has links)
Thesis (M.A. (Communication Studies)) -- University of Limpopo, 2017 / The use of communication technologies has brought changes to our daily ways of doing
things. Youth use technology for different purposes at different locations. As technology
grows everyday with various advantages, its benefits come along with some
disadvantages. Road accidents are one of the major problems that South Africa
experiences. The focus of this study was to explore the danger of texting and driving
and its potentials for road accidents. This research focused on the negative impact of
technology, mainly technological distraction, while driving.
Broadly, this research looks at the social and cultural impact of texting and mobility, with
specific focus on distracted driving. This study is significant in the social analysis of
technology use and distraction; this significance is made more important considering
that there is very limited study of this social issue in South Africa. The always-available
communication culture (such as texting while driving) should be viewed as a
problematic phenomenal.
For data collection, the researcher conducted a survey with adults and youth drivers to
explore the perceptions and attitudes of drivers towards cell phone use, texting and
driving. The researcher also conducted roadside observations of drivers to investigate
the occurrence of distracted driving due to technology use, and interviews were
conducted with Traffic Officers to share their professional experience on observing
incidences of texting and driving.
The study reveals that technology use, texting and driving is a common problem among
young drivers, while adults tend to be more careful and engage less in this activity.
Aspect of the findings of the study shows that 60% of drivers report that they have sent
a text while driving. Moreover, the study explores ways of curbing cell phone use texting
and driving on South African roads. There should be more research on distracted
driving and technology use, so that more suggestions on how to curb technology use
while driving can be offered

Disabilities of Fiction: Reading Madness in Twentieth-Century American Women's LiteraturePeterson, Erica Lyn 05 1900 (has links)
In this dissertation, disability theories frame readings of madness in select works by Shirley Jackson, Sylvia Plath, and Toni Cade Bambara. The dissertation explores the relationship between madness and fiction, with the author demonstrating the productive and generative aspects of madness. Close readings of the literary works emphasize the impact of madness on structural and formal elements including narrative perspective, sustained metaphors, and narrative time. In chapter one, I use the disability theory concepts of narrative prosthesis and aesthetic nervousness to read Jackson's The Haunting of Hill House. In chapter 2, I analyze Jackson's We Have Always Lived in the Castle to explore the concept of unreliable narration, observing similarities between the social model of disability and reader-centric theories of unreliable narration. In chapter 3, I explore unhealthy disability and medical treatment in the sustained metaphors of light and darkness in Plath's hospital stories, "Tongues of Stone," "Johnny Panic and the Bible of Dreams," and "The Daughters of Blossom Street." In chapter 4, I use disability history to read narratives of medical institutionalization in Plath's novel The Bell Jar. In chapter 5, I use Bambara's concept of "other kinds of intelligences" to develop a Black feminist methodology for reading mad intelligences in Bambara's novel The Salt Eaters. In the dissertation's conclusion, I note prejudice against madpersons in recent legal policies promoting involuntary psychiatric institutionalization, using Bambara's short story "The Hammer Man" to demonstrate the violence of such policies.

Administrator Perceptions of the Community College Mission in the State of Mississippi and How it may be Influenced by the Addition of Community College Baccalaureate ProgramsGrizzell, Scharvin S 07 May 2016 (has links)
For many years, community colleges that chose to offer community college baccalaureate (CCB) programs were looked upon in a negative light (Rice, 2015). However, as the need for specialized baccalaureates within specific fields and job markets have continued to grow (McKee, 2005), CCB programs are becoming more widely accepted throughout the United States. In spite of this paradigm shift, Mississippi is one of the remaining states that have not embraced the idea of CCB programs, in spite of its statistical deficiency in regards to baccalaureate degree holding citizens (Williams, 2010). The focus of this study was to explore the perceptions of community college administrators in Mississippi with regards to the influence of CCB programs to the community college mission of institutions in their state. This study indicates that administrators in Mississippi recognize the benefits of offering CCB programs, but do not want CCB programs to take away from the well-established statewide higher education system through mission creep. Many of the strong position statements received overwhelmingly neutral responses. In contrast, Administrators who chose to give their opinion indicated that they are not familiar with how CCB programs are implemented, and do not believe that Mississippi is ready for CCB programs across the state. However, respondents felt that the community college mission is always evolving, should meet students’ needs, and varies from location to location. The findings also show that administrators are favorable to the piloting of CCB programs at a few (1-2) institutions, even though they believe the programs will take funding away from current programs and do not want community colleges evolving into 4-year institutions. The study also concludes that there is a significant difference between institution size and survey questions #18 and #20. There is also a significant difference between length of time in the community college sector and survey questions #15, #17, and #18.

Previous issue date: 2008-05-09 / Nesta tese, a capacidade erro-zero de canais discretos sem memória é generalizada para
canais quânticos. Uma nova capacidade para a transmissão de informação clássica através de canais quânticos é proposta. A capacidade erro-zero de canais quânticos (CEZQ) é definida como sendo a máxima quantidade de informação por uso do canal que pode ser enviada através de um canal quântico ruidoso, considerando uma probabilidade de erro igual a zero. O protocolo de comunicação restringe palavras-código a produtos tensoriais de estados quânticos de entrada, enquanto que medições coletivas entre várias saídas do canal são permitidas. Portanto, o protocolo empregado é similar ao protocolo de Holevo-Schumacher-Westmoreland. O problema de encontrar a CEZQ é reformulado usando elementos da teoria de grafos. Esta definição equivalente é usada para demonstrar propriedades de famílias de estados quânticos e medições que atingem a CEZQ. É mostrado
que a capacidade de um canal quântico num espaço de Hilbert de dimensão d pode sempre ser alcançada usando famílias compostas de, no máximo,d estados puros. Com relação às medições, demonstra-se que medições coletivas de von Neumann são necessárias e suficientes para alcançar a capacidade. É discutido se a CEZQ é uma generalização não trivial da capacidade erro-zero clássica. O termo não trivial refere-se a existência de canais quânticos para os quais a CEZQ só pode ser alcançada através de famílias de estados quânticos não-ortogonais e usando códigos de comprimento maior ou igual a dois. É investigada a CEZQ de alguns canais quânticos. É mostrado que o problema de calcular a CEZQ de canais clássicos-quânticos é puramente clássico. Em particular, é exibido um canal quântico para o qual conjectura-se que a CEZQ só pode ser alcançada usando uma família de estados quânticos não-ortogonais. Se a conjectura é verdadeira, é possível calcular o valor exato da capacidade e construir um código de bloco quântico que alcança a capacidade. Finalmente, é demonstrado que a CEZQ é limitada superiormente pela capacidade de Holevo-Schumacher-Westmoreland.
