In an era of comprehensive school reform, it appears that the voice of teachers is seldom solicited or recognized in the process of planning and implementing school-wide reform. The primary purpose of this study was to report the lived experiences of teachers at Timberton North High School (pseudonym) as it related to the Smaller Learning Community (SLC) reform initiative. Research questions addressed how the faculty experienced the SLC initiative and how their experiences were different from their perceived notion of what SLCs were trying to accomplish and in what ways SLCs initiated a socially constructed understanding of educational purposes. This study utilized a social constructivist lens to identify the nuances of reform and the interplay of effects upon the social, historical, and cultural constructs as they existed on the Timberton North campus and in the minds of the faculty members who participated. The lived experience of the faculty members who participated in this study could be summed up in terms of frustration. The concept of frustration was manifest throughout the data as a unifying thread of a socially constructed understanding. Members of the faculty who formally and informally participated cited various evidences to substantiate their position of frustration, which proved invaluable to the success of this research. The theme of frustration, coupled with disaggregated subthemes, offers a hermeneutic understanding as to what was experienced on the Timberton North Campus. An additional theme of “hope” emerged from the data, as each of the faculty members expressed, in one way or another that something good would come as a result of their SLC efforts in the future. There is considerable attention given in this study to the way the SLC concept was first articulated by the school and district and what was actually realized on the Timberton North campus. This further situates the lived experience within the context of the themes. The themes that were derived in this study have also been situated into the current literature that elaborates on issues of teacher emotionality, educational policy, administrative leadership, and educational reform in general. This particular study is primarily beneficial to those who participated. However, this piece of research will provide some breadth to the growing body of research that involves how teachers influence comprehensive high school reform agendas.

The purpose of this study was to explore how women living with an ADHD diagnosis coloured their experiences throughout life. Women continue to be excluded from clinical research and ADHD is a diagnosis that suffers from a significant male bias. As such, there is limited research about women with ADHD. This study employed a thematic analysis approach, inspired by grounded theory. Four women were recruited online after confirming they met criteria. The four women were interviewed with a semi-structured interview protocol, permitting for organic follow-up questions. Data analysis resulted in the identification of the following 4 themes: Negotiating and navigating education; Experiences of mental health; Socioemotional implications of having ADHD; and Strategies used to cope with ADHD. A total of 11 sub-themes were also identified and were correspondingly organized under appropriate main themes. This research is relevant to any professional working with women with an ADHD diagnosis or who may be querying an ADHD diagnosis.

Background and aims: The individual’s experience of living with epilepsy is often neglected with the dominant focus being upon seizure control. However, the experience of living with epilepsy is more than the seizures. Epilepsy is an illness that is understood in many different ways and the narratives the person draws from will impact their own understanding, experience and management of the condition. Based upon this gap in the literature this study sought to hear the narratives of people diagnosed with epilepsy in adulthood as told to an outsider with the hope of developing understanding, informing clinical practice and improving support for people diagnosed with epilepsy in adulthood. Methodology: A qualitative approach was chosen for this project. A purposive sample of eight individuals diagnosed with epilepsy in adulthood was recruited. Individual interviews were conducted, audio-recorded and transcribed. Narrative analysis was used to analyse the transcripts with a focus upon both what was spoken about and how it was told. Analysis and findings: Each participant is introduced individually, presenting a ‘global impression’ of their narrative. This is followed by a consideration of the similarities and differences across all participants under the shared plots of stories of: onset; changes and challenges; and meanings of epilepsy. Within the shared plot of stories of onset are the storylines of ‘affirmation’ of self; ‘continuation’ of self; biographical disruption and searching for a cause. Within the changes and challenges shared plot there are storylines of: dependency; emotional expression; ‘I try to think positively’ and ‘It’s like talking about someone else.’ Within the final shared plot of meanings of epilepsy there are storylines of: something ‘normal’; something ‘all a bit scary’; something ‘people used to get locked up for’; a ‘hidden illness’ and ‘it’s not to be spoken about.’ The narratives show that having epilepsy is a journey that has different effects on people at different times of their lives and in different contexts. The findings are discussed in relation to clinical implications; strengths and limitations of the methodology and directions for future research.

Transmission Control Protocol (TCP) has been recognized as the most important transport-layer protocol for the Internet. It is distinguished by its reliable transmission, flow control, and congestion control. However, the issue of fair bandwidth-sharing among competing flows was not properly addressed in TCP. As web-based applications and interactive applications grow more popular, the number of short-lived flows conveyed on the Internet continues to rise. With conventional TCP, short-lived flows will be unable to obtain a fair share of available bandwidth. As a result, short-lived flows will suffer from longer delays and a lower service rate. It is essential for the Internet to come up with an effective solution to this problem in order to accommodate the new traffic patterns. With a more equitable sharing of bottleneck bandwidth as its goal, two cross-layer stateless queue management schemes featuring Drop Maximum (DM) and Early Drop Maximum (EDM) are developed and presented in this dissertation. The fundamental idea is to drop packets from those flows having more than an equal share of bandwidth and retain low level of queue occupancy. The congestion window size of a TCP sender is carried in the options field on each packet. These proposed schemes will be exercised on routers and make its decision on packet dropping according to the congestion windows. In case of link congestion, the queued packet with the largest congestion window will be dropped from the queue. This will lower the sending rate of its sender and release part of the occupied bandwidth for the use of other competing flows. By so doing, the entire system will approach an equilibrium point with a rapid and fair distribution of bandwidth. As a stateless approach, these proposed schemes inherit numerous advantages in implementation and scalability. Extensive simulations were conducted to verify the feasibility and the effectiveness of the proposed schemes. For the simple proposed packet discard scheme, Drop Maximum outperforms the other two stateless buffer management schemes, i.e. Drop Tail and Random Early Drop, in the scenario of homogeneous flows. However, in heterogeneous flows, Random Early Drop gains superiority to packet discard schemes due to its additional buffer occupancy control mechanism. To overcome the lack of proper buffer occupancy control, Early Drop Maximum is thus proposed. As shown in the simulation results, this proposed scheme outperforms existing stateless techniques, including Drop Tail, Drop Maximum and Random Early Drop, in many respects, such as a fair sharing of available bandwidth and a short response time for short-lived flows.

In the contemporary United States, power is exerted at both the center of society and its margins. Americans seeking political and cultural capital can cast themselves as insiders, claiming the authority of tradition, or as outsiders, claiming the prophetic voice of the oppressed. Previous scholarship has tended to portray white American evangelicals either as insiders, a theocracy-in-waiting, or as outsiders, a marginalized subculture. In practice, however, white evangelicals claim both positions and move strategically between them. Under certain circumstances, they appeal to the Christian Right’s revisionist history to claim a position at the center of the nation. Under other circumstances, they invoke threats to “Christian America” to claim a position on the margins. This ethnographic study of Christian heritage tourism in Washington, D.C., examines how white evangelical tourists use American history to construct four identities vis-à-vis the nation. Like white American evangelicals more broadly, they see themselves as founders, exiles, victims, and saviors. In addition to ethnography, I draw on intellectual history and material culture studies to account for the dynamic, contradictory, and strategic ways my subjects understand who they are. Written, verbal, and material stories about the American past are key resources white evangelicals use in shaping their identities. On Christian heritage tours and beyond, white evangelicals do history as they plot themselves into narratives about their communities and their nation. This approach, which combines “lived religion” and “lived history,” shows that white evangelicals are political shapeshifters, playing whichever part gives them the most power in a given situation. Their ability to act as both insiders and outsiders is a source of power in a nation that reveres tradition yet cheers for underdogs. While they may talk about leaving behind their outsider roles of exiles and victims, in practice white American evangelicals embrace and defend those roles just as much as they do their insider roles as founders and saviors. Their creative and strategic movement between these roles is a potent political resource that we must understand if we are to make sense of white evangelicals’ political power today. / 2020-11-13T00:00:00Z

This study was inspired by my experiences with a Williams syndrome child, which drew my attention to the meaningful experiences that children with Williams syndrome might have with music. The problem of the study can be defined in terms of five aspects. Firstly, individuals diagnosed with Williams syndrome suffer medically, socially and cognitively (Levitin & Bellugi, 1998:358-359) and music seems to be an aspect of their lives that could make things easier for them. Secondly, those suffering from Williams syndrome seemingly struggle to adapt to their social surroundings (Bellugi et al., 1994:5). The third aspect that defines the problem is that families of individuals with Williams syndrome in South Africa do not have sufficient access to educational facilities that are equipped to work with their children. This forces them to home school their children without the ability to educate them optimally. Fourthly, the research problem also stems from the lack of awareness about the lived musical experiences of individuals living Williams syndrome. It becomes clear that heightening awareness of the lived musical experiences of Williams syndrome individuals has not been addressed in research. Lastly, researchers have yet to undertake in-depth qualitative studies on the meaning of musical experience for the learning experiences of those suffering from Williams syndrome. The purpose of this interpretative phenomenological analysis (IPA) is to understand the lived musical experiences of individuals living with Williams syndrome in Southern Africa1. Williams syndrome is defined as a rare genetic disorder which presents when around 20 genes are deleted on chromosome 7 at conception (Bellugi et al., 2007:98). This study follows an IPA approach and aims to gain insight into how participants understand their lived musical experiences. The theoretical foundations for IPA are based on “three key areas of philosophical knowledge, namely phenomenology, hermeneutics and idiography” (Smith et al., 2009: 11). For this study data were collected by conducting in-depth semi-structured interviews with three purposefully selected participants. The interview transcriptions were then analysed separately using ATLAS.ti 7 computer software. After each interview transcript was analysed individually, superordinate themes emerged from a cross-case analysis. The results of the study revealed four superordinate themes regarding the musical experiences of the three Williams syndrome participants: a passion for performing, fostering friendships, lightens the load and dependent on music. The study found that music contributes to the overall well-being of the three participants in a way that allows them to feel accepted by others and to escape the label of being diagnosed Williams syndrome. / MMus (Musicology), North-West University, Potchefstroom Campus, 2015

Heidegger was not always preoccupied, as he himself would later come to believe, with the question regarding the sense of being. Eight years before he published his magnum opus, Sein und Zeit, in 1927 he was totally devoted to finding a systematic way to bringing “life” as the ultimate source of meaning to explicate itself. In the years between 1919-1923, “life”, and not “being”, is the matter of philosophy par excellence, only to be disregarded, even refuted as a “proper” matter of philosophy in the subsequent years. In this paper I examine the philosophical motives that led Heidegger from life to being. The purpose of this project isto trace the emergence of the “thinking of being” in “life philosophy.” I will show that the transition from “life” to “being” is not at all as radical as Heidegger wants it to be whenever he voices his concerns about the metaphysical grounds of life philosophy. When “life” is understood in the exact terms in which Heidegger himself understands it in the years between 1919-1923 then, I argue, the transition to being is more a radicalization, and by no means an abandonment, of life philosophy. In the process of elaborating an understanding of life so fundamentally sympathetic to life that it can claim itself to be life’s own self-understanding, Heidegger comes gradually to realize the importance of life’s own way of living understandingly, the performative sense in which it [life] itself understands itself to be, for the very effort to understand life. Life is now interpreted as a way of being for which this very being, its way of being, is an issue for itself. In the first chapter I go back to the original motives that led Heidegger to choose life, lived experience, as the proper topic of philosophy. It is here that Heidegger discovers that philosophy is ultimately about an entity that is somehow concerned with itself already in being-engaged to “something” other than itself. Intentionality is interpreted as the manner in which an entity is playing itself out, as it were, in engaging a world. In the second chapter, I follow his elaborations of this newly discovered topic, the “personal” character of experience, with a focus on the unique way in which he develops it by both rejecting the Neokantian approach to life and by critically appropriating Dilthey’s conception of lived experience. The third chapter presents Heidegger’s “insights” into life – which will remain unchanged, only put to different uses when the topic changes from life to being. The fourth chapter takes up the issue of how life is (and is itself)in being referred to its own past. Here I show how life is found to be “in need” to appropriate what it has been as the way in which it can be itself. Chapters five and six delve into the proper relation between living and philosophizing by focusing on how life is living-in-understanding. It is shown here how Heidegger elaborates, unfortunately insufficiently, his method of “formal indicators” which will enable him to interpret life as a “way of being.” Such interpretation leaves open the possibility, however, of either interpreting life as the manner in which being itself can be experienced or, as Heidegger does in the first early years, or interpreting being as the manner in which life can come to itself. Early Heidegger can only justify the former interpretation: in developing for itself a sense of being which can only be performed as a way in which life lives, life develops a genuine self-understanding.

Nuclear accidents and weapons tests are monitored by a worldwide network of air sensors, seismic detectors and several other techniques. At the site of the incident, contaminants are distributed and can provide insight into the time of the incident and type of incident. That information can then be used to affect policy decisions or better understand health risks. In order to evaluate a post nuclear test scenario, we must better understand the background readings at potential test sites where false positive or false negative allegations are more likely (e.g. the Nevada Test Site, the Chernobyl Nuclear Power Plate, etc.) Data from these sites have been compiled and compared to high purity germanium detector background readings and activities from a hypothetical nuclear weapon test. The results indicate that the following nuclides would be the best indicator of a recent nuclear test: ⁸⁹Sr, ⁹¹Y, ⁹⁵Zr, ¹⁰³Ru, ¹²⁶Sb, ¹²⁹[superscript m]Te, ¹⁴⁷Nd, ¹⁵⁶Eu. Nuclides such as ⁹¹Sr or ⁹⁷Zr have a steady state concentration due to plutonium spontaneous fission thus would not be a good indication of a recent nuclear test. / text

Accidentally killing or feeling responsible for another person’s death constitutes a traumatic event that is unique from any other traumatic stressor. Considering the frequency of incidents such as deaths resulting from road traffic accidents (RTAs), it is surprising that the academic literature regarding those who have accidentally killed is almost none existent. This study therefore aimed to gain an insight into the lived experiences of drivers who have caused an accidental death. Five participants were recruited through an on-line advertisement; all were drivers directly involved in a RTA that occurred suddenly, unexpectedly, without planning or intention and resulted in the death of a person. An interpretative phenomenological approach was used to analyse data collected through semistructured interviews. Three main themes emerged from the participants’ accounts: trying to make sense of a life changing moment; struggling to cope with the trauma of causing a death and a changed sense of self. These findings are discussed in relation to the relevant literature. Clinical implications, methodological limitations and directions for future research are presented. The study provides a valuable insight for any professional working with people who have caused, or feel responsible for, an accidental death. It is hoped that this study will be a catalyst for discussion and future research.
