Social Aspects of Food-Sensitive Adults

People living with food-related illnesses find themselves subjugated by commonly held ideologies causing awkwardness in social situations. The current study is a qualitative analysis addressing how people with celiac disease (CD) navigate social situations in light of dominant beliefs that influence behaviors. Initially, I identify macro-level patriarchal, religious, sexist, ableist and etiquette-related commensality ideologies that disadvantage those with CD. Drawing from the communication narrative sense making (CNSM) theory that supports storytelling and memorable messages as a sense-making tool for individuals diagnosed with chronic illness and their family members, this work highlights retrospective stories and memorable messages from 20 randomly selected interviews (out of 66 conducted). Further, I discuss how individual identity evolves while redefining truths in light of having a disease. Three overarching themes emerge from the analysis: 1) questioning ideologies to form revised truths, 2) familial adaptation or non-adaptive responses, and 3) identity transformation. The first theme contemplates what is considered true depending on dominant ideologies on food-related expectations. The second theme examines social stigma that can result when a person in a given social group no longer conforms to these basic, assumed beliefs; or conversely, familial compassion that occurs when family and friends do conform. Finally, the third theme traces the evolution of an individual\u27s transformation when faced with redefining his or her identity, standing with courage and fortitude to influence those around him/her to align with new revised truths that may yield compliance or resistance. This study expands the current knowledge by associating how those with food sensitivities (FS) or CD find themselves subjugated by dominant ideologies that permeate behavior. The dissertation adds to the communication studies conversation by illuminating a seldom-studied population of adults living with the hidden disability of FS or CD, and expands the CNSM by contributing a concept I am calling a homeostatic shift, or the process where rituals are disrupted, causing the person with CD to enter into a state of liminality or transition, reforming truths and eventually shifting to a new state of equilibrium living with the realization that all experiences thereafter are shrouded with the veil of disease

The orchestra conductor

In musical and social representations, the orchestra conductor is portrayed as a figure of autocratic power, one whose authority is recognized and accepted by all. In reality, however, this authority is a social construct which is created over the course of the rehearsals. Moreover, it is highly dependent on the type of legitimacy held by the conductor, i.e., contractual legitimacy, which remains minimal, or professional legitimacy, which is based on the instrumentalists’ approval and recognition. This article attempts to understand which criteria allow this professional legitimacy to be established, for only this can allow the musicians to truly embrace the conductor’s interpretation. The first part of this article presents our ethnographic study of three symphonic orchestras. The second part distinguishes between contractual legitimacy and professional legitimacy and then explores the process by which the latter is constructed in orchestra-conductor interactions

Flow Monitoring Explained: From Packet Capture to Data Analysis With NetFlow and IPFIX

Flow monitoring has become a prevalent method for monitoring traffic in high-speed networks. By focusing on the analysis of flows, rather than individual packets, it is often said to be more scalable than traditional packet-based traffic analysis. Flow monitoring embraces the complete chain of packet observation, flow export using protocols such as NetFlow and IPFIX, data collection, and data analysis. In contrast to what is often assumed, all stages of flow monitoring are closely intertwined. Each of these stages therefore has to be thoroughly understood, before being able to perform sound flow measurements. Otherwise, flow data artifacts and data loss can be the consequence, potentially without being observed. This paper is the first of its kind to provide an integrated tutorial on all stages of a flow monitoring setup. As shown throughout this paper, flow monitoring has evolved from the early 1990s into a powerful tool, and additional functionality will certainly be added in the future. We show, for example, how the previously opposing approaches of deep packet inspection and flow monitoring have been united into novel monitoring approaches

A Cloud Platform-as-a-Service for Multimedia Conferencing Service Provisioning

Multimedia Conferencing is the real-time exchange of media content (e.g. voice, video and text) between multiple participants. It is the basis of a wide range of conferencing applications such as massively multi-player online games and distance learning applications. For faster development as well as cost efficiency, developers of such conferencing applications can use conferencing services (e.g. dial-in audio conference) provided by third-parties. However, the third-party service providers face several challenges with respect to conferencing service provisioning (i.e. service development, deployment and management). One challenge is mastering complex low-level details of conferencing technologies, protocols and their interactions. Another challenge is resource elasticity. Number of conference participants varies during runtime. So resource utilization in an elastic manner is a critical factor to achieve cost efficiency. Cloud Computing can help tackle these challenges. It is a paradigm for swiftly provisioning a shared pool of configurable resources (e.g. services, applications, network and storage) on demand. It has three main service models: Infrastructure-as-a-Service (IaaS), Platform-as-a-Service (PaaS) and Software-as-a-Service (SaaS). Using a PaaS, service providers can provision conferencing services easily and offer them as SaaS. Nonetheless, cloud-based provisioning of conferencing services still remains a big challenge due to the shortcomings of existing PaaS. In this thesis, a PaaS architecture for conferencing service provisioning is proposed. It is based on a business model from the state of the art. It relies on conferencing IaaSs that, instead of VMs, offer conferencing substrates (e.g. dial-in signaling, video mixer and audio mixer). The conferencing PaaS enables composition of new conferences from substrates on the fly. Moreover, it provides conferencing service providers, who are experienced in programming, with high-level interfaces to abstract the internal complexities of conferencing. In order for PaaS to scale ongoing conferences elastically, an algorithm is also presented in this thesis. The conferencing PaaS is prototyped and performance measurements are made. The proposed algorithm’s performance is also evaluated
