Migrating from a wired to a wireless implementation for communication system used in industrial applications is a logical move to avoid the many shortcomings associated with wires. When operated under harsh environments, those wires can break and could cause not only damage to the system but also endanger human lives. However, it is not well documented how well a wireless protocol can work under such harsh industrial environments. This thesis attempts to answer this research question in the point of view of gauging the performance of a wireless protocol under the influence of electromagnetic noise. More specifically, the type of noise signal that is the focus of this investigation is the random, pulsed type (e.g., discharges caused by sparking) that creates a hyperbolic broadband disturbance in the frequency domain. Consequently, a fractal noise model is used to study noise of this nature. The steps toward achieving this goal include: requirements gathering, wireless technology selection; noise modelling and synthesis; real noise capture and analysis to validate the chosen noise model; high-frequency fractal noise emulation in hardware; the use of a novel noise injection method for empirical work; and the conducting of a controlled synthetic noise-to-wireless node performance evaluation to obtain performance measure in the form of packet error rate (PER). Performance data in terms of PER versus signal-to-noise ratio (SNR) for various nodes separation have been collected. There were three significant findings: the obtained performance curves follow the standard 'S' trend; for a specific desired reliability (denoted by a certain PER), the SNR at the transmitter needs to be boosted as the correlation of the noise being present increases; and the maximum distance between nodes separation for a certain reliability to be achieved depends exponentially with the transmitter‟s SNR. The relationship in the third finding assists in placement of wireless nodes, which in turn can determine the minimum amount of wireless nodes required for an industrial system to reach the desired system reliability, thus boasting network cost saving.

Decomposition methods based on the hierarchical partitioning of the state space of queueing network models offer powerful evaluation tools for the performance analysis of computer systems and communication networks. These methods being conventionally implemented capture the exact solution of separable queueing network models but their credibility differs when applied to general queueing networks. This thesis provides a universal information theoretic framework for the implementation of hierarchical decomposition schemes, based on the principle of minimum relative entropy given fully decomposable subset and aggregate utilization, mean queue length and flow-balance constraints. This principle is used, in conjuction with asymptotic connections to infinite capacity queues, to derive new closed form approximations for the conditional and marginal state probabilities of general queueing network models. The minimum relative entropy solutions are implemented iteratively at each decomposition level involving the generalized exponential (GE) distributional model in approximating the general service and asymptotic flow processes in the network. It is shown that the minimum relative entropy joint state probability, subject to mean queue length and flow-balance constraints, is identical to the exact product-form solution obtained as if the network was separable. An investigation into the effect of different couplings of the resource units on the relative accuracy of the approximation is carried out, based on an extensive experimentation. The credibility of the method is demonstrated with some illustrative examples involving first-come-first-served general queueing networks with single and multiple servers and favourable comparisons against exact solutions and other approximations are made.

Book Summary: Essential Breakthroughs: Conversations About Men, Mothers, and Mothering thinks from the nexus of gender, essentialism, and care. The authors creatively blend the philosophical and the personal to collectively argue that while gender is essential to our social and theoretical definitions of care, it is dangerously co-opted into naturalized discourses, which limit particular identities and negate certain forms of care. The perspectives curated in Essential Breakthroughs illuminate how care, as a respected and productive cultural ethic, is neither inherent nor instinctual for any human, but is learned and fostered. The chapters are informed by feminist, queer, and trans politics, wielding post-structuralist methodologies of unlearning and deconstruction, while maintaining the maternal lens as a credible feminist analytical tool and not as a gender-essentialist practice.

Introduction: In 1996, East Tennessee State University (ETSU) reinforced its historical commitment to multidisciplinary community engagement by developing a graduate level community partnerships program in the Division of Health Sciences. While the university's earlier health partnership efforts relied primarily on curricular innovation, the approach to graduate health professions education was to seed a series of curricular enhancements and interdisciplinary, community-based learning experiences and service into traditional curricula. This paper presents the experience of one school in crafting a regional network that became the basis of a division-wide graduate level teaching and learning initiative. Innovations and Evaluation: Carefully selected planning and implementation techniques enabled multidisciplinary practitioners and community members from across a 20-county region to participate with university faculty in training ETSU learners in community-based medical care. By year four of the project, curricular "enhancements" were institutionalized in over five departments across the Division and engaged 1160 medical residents and graduate learners in a give - get model of health education. Programme evaluation methodology was collaboratively defined and documentation of programme effort and outcomes regularly reported and strategically reviewed. Conclusions: Programme evaluation demonstrates mutual benefit to community and university. Faculty involvement in programme activity increased fourfold and community involvement in training of health professions graduate learners increased threefold by year four. Educational innovations were adopted into traditional curricula, thousands of hours of clinical services were provided to underserved communities and the university-community team forged by network links continues to promote multidisciplinary interests through joint public policy endeavors.

Despite advancements in asthma treatment and diagnosis, asthma still remains the number 1 cause for hospitalizations in school-aged children. This usability study aimed to develop a child-friendly interactive narrative, Okay with Asthma v2.0, based on the Biopsychosocial Family Model using feedback from children. This fun and kid-friendly program encourages children to manage their own asthma with the help of peers, families, communities, and health care services. With these support structures, children can identify and avoid triggers, monitor their asthma, manage their condition with medications based on an action plan, and learn to live happily with asthma.

Human papillomavirus is the most frequently occurring sexually transmitted infection and has been recognized as the necessary cause of cervical cancer. Understanding the shift in public awareness caused by recent changes to cervical prevention is critical to addressing cervical cancer disparities in Appalachia. Since the human papillomavirus vaccine was approved for prevention, little data have been collected regarding human papillomavirus risk assessment and vaccine perceptions among Appalachian women. The purpose of the authors in this study was to investigate communication and cultural issues via a social scripting framework that could influence human papillomavirus vaccine uptake among southern Appalachian women; and explore participants' perceptions of human papillomavirus, cervical cancer, and the vaccine. A qualitative, descriptive design was employed to examine these issues in eight counties in northeast Tennessee and southwest Virginia. Thirty-nine women aged 18-49 years participated in a single individual interview or focus group session from October 2007 through August 2008. Interview and focus group data were audio-taped and transcribed verbatim. Two major themes emerged from the data: the human papillomavirus vaccine protection dilemma and spheres of silence surrounding the human papillomavirus vaccine protection dilemma. Study findings suggested areas for future research and may assist healthcare professionals in approaching southern Appalachian women as they make decisions regarding cervical cancer prevention.

Purpose – The purpose of this paper is to explore narratives in a new nonprofit arts center. It includes the macro-, meso-, and personal narratives that keep the center organized in the midst of the chaotic everyday activities. It advocates the explanatory force of narrative as an alternative to organizational life cycle theory for understanding organizational startups. Design/methodology/approach – This narrative ethnography involved participant observation, full participation, and narrative interviews over a three-year period. Using grounded theory, narratives were examined to discover how they engendered and maintained order. Findings – This paper contributes to the understanding narratives as a constitutional organizing and sensemaking process, including the narratives of “Do It Yourself,” and economic production, family and home, and personal narratives that constitute community, community boundaries, and identity, adding to our knowledge of organizing. Research limitations/implications – The research examined only one local nonprofit arts center, therefore the findings are specific to this site and the same types of narratives may not necessarily be found in other nonprofits. Originality/value – This paper examines a nonprofit during start-up. It validates support for the examination of organizations through narrative ethnography and narrative interviewing. It purports that narratives constitute social identity, rather than being the evidence of social identity.

Purpose: The purpose of this paper is to examine the rituals and communicative practices that simultaneously create community, out-groups and perceptions of stigma at a local comic book retail organization through autoethnography. As such this piece explores personal identity, comic book culture and how this comic book shop acts as important third place as defined by Oldenburg. Design/methodology/approach: Autoethnography allows for the simultaneous research into self, organizations and culture. As a layered account, this autoethnography uses narrative vignettes to examine a local comic book retail organization from the first person perspective of a collector, a cultural participant and geek insider. Findings: The term geek, once brandished as an insult to stigmatize, is now a sense of personal and cultural pride among members. Various rituals including the “white whale” moment and the specialized argot use help maintain community in the comic book shop creating a third place as categorized by Oldenburg. However, these shared communication practices and shared meanings reinforce the hegemonic masculinity of the store, leading the author to wonder if it can maintain its viability going forward. Originality/value: This autoethnography was performed at a local comic book shop, connecting communicative and ritual practices to organizational culture, hegemonic masculinity, geek culture and personal identity. It also argues that one need not be an embedded organizational insider to perform organizational autoethnography.
