description: The recognition of one's exercise of sexual rights and reproductive rights, including the right to health, sexual health and reproductive health are critical matters. Also critical, and especially for women in a patriarchal society are rights related to contraception, natality control, and education on fertility matters since these rights contribute to women's control over their own bodies. In Peru, between 1995 and 1998, and as recently as May of 2003, documented evidence points to legislation and institutional practices that continue to deny women these rights thus affecting their lives, the lives of their children and the outcome for their unborn. The Peruvian government, in enacting the 1995 National Population Law (hereinafter 1995 NPL) applied under the "1996--2000 Family Planning Program" and guided by the "Procedural Manuals for Sterilisations" reinforces these beliefs. In so doing, the state contributes to the oppression and domination of marginalised social groups while alienating some bodies from fertility choices and transforming them into objects of manipulation. Four main chapters constitute this thesis, as well as an introduction, conclusion, and appendices. The introduction presents an overview of reproductive health, or lack thereof, in Peru. Chapter One introduces the examined material through a literature review, as the basis for the following chapters. Chapters Two and Three, address theory and methodology respectively acting as lenses and suggesting ways of examining the oppression that disables marginalized social groups. In light of the foregoing chapters, Chapter Four analyses the stories of oppression and domination of marginalized social groups, embodied in state sanctioned practices of fertility control. Bringing the margins to the centre, this portion of the story relies on the testimony of the women themselves, reflecting their voices and opinions as producers of knowledge rather than victims. This research work closes with questions formulated to elicit further stories, and reaffirms its aim to serve as a basis for political consciousness, social change and activism through academic means.

description: Model transformations are among the key concepts of model-driven engineering (MDE), and dedicated model transformation languages (MTLs) emerged with the popularity of the MDE paradigm about 15 to 20 years ago. MTLs claim to increase the ease of development of model transformations by abstracting from recurring transformation aspects and hiding complex semantics behind a simple and intuitive syntax. Nonetheless, MTLs are rarely adopted in practice, there is still no empirical evidence for the claim of easier development, and the argument of abstraction deserves a fresh look in the light of modern general-purpose languages (GPLs) which have undergone a significant evolution in the last two decades. In this paper, we report about a study in which we compare the complexity and size of model transformations written in three different languages, namely (i) the Atlas Transformation Language (ATL), (ii) Java SE5 (2004-2009), and (iii) Java SE14 (2020); the Java transformations are derived from an ATL specification using a translation schema we developed for our study. In a nutshell, we found that some of the new features in Java SE14 compared to Java SE5 help to significantly reduce the complexity of transformations written in Java by as much as 45\%. At the same time, however, the relative amount of complexity that stems from aspects that ATL can hide from the developer, which is about 40\% of the total complexity, stays about the same. Furthermore we discovered that while transformation code in Java SE14 requires up to 25\% less lines of code, the number of words written in both versions stays about the same. And while the written number of words stays about the same their distribution throughout the code changes significantly. Based on these results, we discuss the concrete advancements in newer Java versions. We also discuss to which extent new language advancements justify writing transformations in a general purpose language rather than a dedicated transformation language. We further indicate potential avenues for future research on the comparison of MTLs and GPLs in a model transformation context.

description: Lyα emission is possibly the best indirect diagnostic of Lyman continuum (LyC) escape since the conditions that favor the escape of Lyα photons are often the same that allow for the escape of LyC photons. In this work, we present the rest-frame UV-optical spectral characteristics of 11 Lyα emitting galaxies at 3 < z < 6—the redshift range that optimizes between intergalactic medium attenuation effects and temporal proximity to the epoch of reionization. From a combined analysis of JWST/NIRSpec and MUSE data, we present the Lyα escape fraction and study its correlation with other physical properties of galaxies that might facilitate Lyα escape. We find that our galaxies have low masses (80% of the sample with log 10 M ⋆ < 9.5 M ⊙ ), compact sizes (median R e ∼ 0.7 kpc), low dust content, moderate [O iii]/[O ii] flux ratios (mean ∼ 6.8 ± 1.2), and moderate Lyα escape fractions (mean f esc Ly α ∼ 0.11). Our sample shows characteristics that are broadly consistent with low-redshift galaxies with Lyα emission, which are termed as “analogs” of the high-redshift population. We predict the LyC escape fraction in our sample to be low (0.03-0.07), although larger samples in the postreionization epoch are needed to confirm these trends.
Optimization of device control for the flicker perimeter.

description: To optimize the function of a prototype flicker perimeter, it is important to reduce the amount of time required to change test target location in the visual field while maintaining the random presentation order necessary to ensure accurate results. The purpose of this project is to develop and test a software algorithm that achieves these two goals simultaneously. I have developed an algorithm for the Flicker perimeter that maximizes the efficiency of travel in the motors governing test target projection. This will reduce the time between test trials as well as the entire sequence, thus limiting the fatigue factor in testing. The algorithm incorporates a component that maintains a pseudo-random order of presentation. I have developed and constructed a simulation of the functioning perimeter by designing and reengineering the system program and incorporating both the original presentation algorithm (Random) and the optimizing algorithm (Optimized).

Analysis of gases in ice from regions of northern Canada

description: Gas bubbles in ice hold relevance to the origin and process of formation, distinguishing between an atmospheric or dissolved origin. An extraction line was built to isolate gases from ice, and tested using glacial, aufeis and ground ice from the Canadian Arctic. A newly developed mass spectrometry technique was used to analyze the gases for gas ratios of three principal atmospheric gases (N2, O2, and Ar) as well as 18O and 15N of these gases. O2/Ar and N2/Ar ratios demonstrate differences between atmospheric gas in glacial ice and gases exsolved from freezing water, due to the difference in their relative solubilites. Glacial and ground ice contained higher oxygen-18 values than the atmosphere and aufeis ice. Results for glacier ice show that isotopic and gas ratios of atmospheric gas entrapped during glacial ice formation change through gravitational settling. Aufeis ice bubbles originate as dissolved gas with alteration by excess air addition and/or mixing with snow pack. In the ground ice sampled, low oxygen concentrations and high delta 18O values, indicate respiration prior to formation.

description: As the alignment of a feed antenna to a steerable reflectarray becomes increasingly complicated at upper mm-wave frequencies, illuminating the structure from the far field is desirable. Simultaneously, the required fabrication precision makes large arrays expensive, effectively limiting the size. Consequently, spill-over feed radiation results in specular reflections, degrading the array’s far-field pattern. To mitigate these undesired reflections, planar periodic structures can be employed to implement spatial filtering. Three designs that reduce specular reflections of a planar surface, caused by an obliquely-incident wave at 240 GHz, are proposed. Additional to standard evaluation of the absorptivity per unit cell, this paper examines the suppression mechanism by studying the scattered far field of size-limited structures. To verify each design, the frequency dependency of the specular reflection and the far-field pattern of a small array are measured. In accordance with simulations, two polarization-maintaining variants feature 10 dB attenuation, whereas a mode-converting design achieves 23 dB.

description: We present a comprehensive catalog of observations and stellar population properties for 23 highly secure host galaxies of fast radio bursts (FRBs). Our sample comprises 6 repeating FRBs and 17 apparent nonrepeaters. We present 82 new photometric and 8 new spectroscopic observations of these hosts. Using stellar population synthesis modeling and employing nonparametric star formation histories (SFHs), we find that FRB hosts have a median stellar mass of ≈109.9 M ⊙, mass-weighted age ≈5.1 Gyr, and ongoing star formation rate ≈1.3 M ⊙ yr-1 but span wide ranges in all properties. Classifying the hosts by degree of star formation, we find that 87% (20 of 23 hosts) are star-forming, two are transitioning, and one is quiescent. The majority trace the star-forming main sequence of galaxies, but at least three FRBs in our sample originate in less-active environments (two nonrepeaters and one repeater). Across all modeled properties, we find no statistically significant distinction between the hosts of repeaters and nonrepeaters. However, the hosts of repeating FRBs generally extend to lower stellar masses, and the hosts of nonrepeaters arise in more optically luminous galaxies. While four of the galaxies with the clearest and most prolonged rises in their SFHs all host repeating FRBs, demonstrating heightened star formation activity in the last 2100 Myr, one nonrepeating host shows this SFH as well. Our results support progenitor models with short delay channels (i.e., magnetars formed via core-collapse supernova) for most FRBs, but the presence of some FRBs in less-active environments suggests a fraction form through more delayed channels.

description: Two-photon Raman transitions are commonly used to facilitate π/2- and π-pulses in atom interferometry, and are the analogue of beam splitters and mirrors in optical interferometers. In practice, these transitions are driven by laser light which can be described semi-classically as quasi-coherent states. Thus quantization effects are averaged out due to the broad photon distribution in typical beams. However, technological progress moves towards the use of optical cavities due to their superior optical properties. Theoretical modeling of such configurations demands a second-quantized description of the light fields which we pursue based on the light-matter interaction of two second-quantized single-mode light fields and an effective two-level atom. In this thesis we derive and investigate a two-photon Rabi model with center-of-mass motion including intensity-dependent operator-valued couplings between the light field and the center-of-mass motion. We show, that under certain approximations we obtain an effective Jaynes-Cummings model with a center-of-mass dependent detuning.

description: Emergency medical service (EMS) personnel frequently encounter emotionally stressful or even traumatic incidents in their line of duty. In this study, a checklist of emotionally stressful events for the German EMS was introduced. A mixed-method approach was used to identify mission events that were critical for the development of mental and physical stress symptoms. Data were collected in a cross-sectional sample of 102 EMS employees. A quantitative content analysis of the participants’ worst experiences on duty indicated, traumatic missions to be a concatenation of two to five emotionally stressful events. Rescue missions were experienced as traumatic if (i) EMS personnel became victims of attacks or threats; (ii) certain circumstances caused them to give up their professional detachment from patients; (iii) EMS personnel perceived the overall mission as exceptionally tragic. In subsequent correlation analyses, the corresponding checklist items showed consistent positive associations with the post-traumatic, depressive and physical stress symptoms among the study cohort. Within the exploratory regressions, the sum score of critical on-duty exposures contributed incrementally to the prediction of mental and physical stress symptoms when non-work-related trauma exposure and perceived social support were also considered. Findings point toward the importance of considering the cumulative burden of critical incidents for the long-term health of EMS personnel. Future research is needed to investigate, how on-duty trauma affects the social support EMS personnel received from their work and personal relationships.

description: Coherent optical OFDM (CO-OFDM) has recently been proposed and the proof-of-concept transmission experiments have shown its extreme robustness against chromatic dispersion and polarization mode dispersion. In this paper, we first review the theoretical fundamentals for CO-OFDM and its channel model in a 2x2 MIMO-OFDM representation. We then present various design choices for CO-OFDM systems and perform the nonlinearity analysis for RF-to-optical up-converter. We also show the receiver-based digital signal processing to mitigate self-phase-modulation (SPM) and Gordon-Mollenauer phase noise, which is equivalent to the midspan phase conjugation.
A comparative study of high-dose chemotherapy with autologous hematopoietic progenitor cell transplantation versus conventional chemotherapy as treatment for metastatic breast cancer.

description: Objectives. Data from one small randomized trial has suggested a benefit for high-dose chemotherapy/autologous hematopoietic progenitor cell transplantation (HDCT/AHPCT) as compared with conventional chemotherapy (CCT) in patients with metastatic breast cancer. However, the study was considered to have had some limitations based on methodology, analysis, and sample size. The present study sought to compare differences in outcome in patients with metastatic breast cancer undergoing HDCT/AHPCT as compared with historical controls undergoing CCT. The principal endpoints analyzed were overall survival and time to first failure after beginning chemotherapy. Secondary outcomes included an analysis of predictors of time to first recurrence of breast cancer, analyses of prognostic factors for overall survival at recurrence, of time to first failure from the time of beginning chemotherapy, and for survival after HDCT/AHPCT. Conclusions. The use of HDCT/AHPCT in metastatic breast cancer may confer advantages with respect to overall survival and time to first failure after beginning chemotherapy. These advantages appear to be independent of the effects of selection bias and variously cited prognostic factors. This benefit if confirmed in ongoing randomized trials will have to be considered in light of differences in cost and quality of life between the two therapeutic modalities.

description: Surgical resection is the leading treatment of most solid tumours, however surgical stress creates an immunosuppressive environment that promotes metastases. A global decrease in T cell numbers and function post-surgery has been documented. However, the effect on tumour associated antigen (TAA)-specific T cells remains unclear. The objective is therefore to evaluate the impact of surgical stress on TAA-specific adaptive T cell immunity. Melanoma tumour-bearing C57BL/6 mice were vaccinated using AdhDCT, an adenovirus expressing dopochrome totaumerase (DCT), a melanoma TAA, and underwent abdominal nephrectomies to induce surgical stress. Surgical stress decreased the number of splenic cytotoxic T cells (CTLs) and their capacity to produce immunostimulatory cytokines (IFNγ and TNFα), as determined by flow cytometry. A perioperative accumulation in CTL-suppressive MDSCs was observed and demonstrated a direct suppression of CTL IFNγ and TNFα production and secretion. Understanding the mechanisms of perioperative T cell dysfunction will facilitate the development of targeted immunotherapies.

description: Hospital-acquired diarrhoea (HAD) is common, and often associated with gut microbiota and metabolome dysbiosis following antibiotic administration. Clostridioides difficile is the most significant antibiotic-associated diarrhoeal (AAD) pathogen, but less is known about the microbiota and metabolome associated with AAD and C. difficile infection (CDI) with contrasting antibiotic treatment. We characterised faecal microbiota and metabolome for 169 HAD patients (33 with CDI and 133 non-CDI) to determine dysbiosis biomarkers and gain insights into metabolic strategies C. difficile might use for gut colonisation. The specimen microbial community was analysed using 16 S rRNA gene amplicon sequencing, coupled with untargeted metabolite profiling using gas chromatography-mass spectrometry (GC-MS), and short-chain fatty acid (SCFA) profiling using GC-MS. AAD and CDI patients were associated with a spectrum of dysbiosis reflecting non-antibiotic, short-term, and extended-antibiotic treatment. Notably, extended antibiotic treatment was associated with enterococcal proliferation (mostly vancomycin-resistant Enterococcus faecium) coupled with putative biomarkers of enterococcal tyrosine decarboxylation. We also uncovered unrecognised metabolome dynamics associated with concomitant enterococcal proliferation and CDI, including biomarkers of Stickland fermentation and amino acid competition that could distinguish CDI from non-CDI patients. Here we show, candidate metabolic biomarkers for diagnostic development with possible implications for CDI and vancomycin-resistant enterococci (VRE) treatment.

description: E-commerce provides a platform where complete strangers from all over the world have the chance to transact with each other. Reputation is a key factor in the success of such transactions, therefore reputation systems are in widespread use to help participants build their online reputation. This thesis analyzes current reputation systems and studies how to design architectures for online reputation systems. Based on the shortcomings found in current reputation systems, this thesis proposes and implements a reputation architecture called ORAS (online reputation aggregation system) Plus which provides a portable reputation mechanism for Web users. With ORAS Plus, users can search others' global reputation and obtain their own reputation cards which can be displayed at any website. ORAS Plus can help users know someone's online behaviors all over the Internet. More importantly, it allows users to take their existing reputation from one website to other websites where they are unknown to others.

description: Various synthetic biomaterials are used to replace lost or damaged bone tissue that, more or less successfully, osseointegrate into the bone environment. Almost all biomaterials used in orthopedic medicine activate the host-immune system to a certain degree. The complement system, which is a crucial arm of innate immunity, is rapidly activated by an implanted foreign material into the human body, and it is intensely studied regarding blood-contacting medical devices. In contrast, much less is known regarding the role of the complement system in response to implanted bone biomaterials. However, given the increasing knowledge of the complement regulation of bone homeostasis, regeneration, and inflammation, complement involvement in the immune response following biomaterial implantation into bone appears very likely. Moreover, bone cells can produce complement factors and are target cells of activated complement. Therefore, new bone formation or bone resorption around the implant area might be greatly influenced by the complement system. This review aims to summarize the current knowledge on biomaterial-mediated complement activation, with a focus on materials primarily used in orthopedic medicine. In addition, methods to modify the interactions between the complement system and bone biomaterials are discussed, which might favor osseointegration and improve the functionality of the device.
Brand salience for durables: an empirically based model

description: The research reported in this paper proposed and tested a model of brand salience for durables, which incorporates knowledge and brand image as antecedents. A full model of brand salience has not been tested previously, nor has a model of brand salience for durables been tested. A quasi-experimental method was utilised. Respondents undertook a free recall exercise using category cues, and then completed multi-item measures of brand knowledge, brand associations, and purchase likelihood. Past purchase was tested via a recall exercise. A usable sample of 270 respondents was gained, and the data were analysed using Structural Equation Modelling (SEM). Analysis of the data found support for a model of brand salience for the durable category, and found a relationship between brand salience and most recent brand purchased. This paper contributes to the field of branding by proposing and testing a model of brand salience. The research reported in this paper may suggest that advertisers need to design their communications to increase accessibility of brands in the memory of consumers, and that the last brand purchased by consumers influence recall, especially in the consumer durable category.

description: Since their first discovery in the 19th century, microsporidian species have been found to be successful obligate intracellular parasites capable of infecting a wide variety of hosts including economically and ecologically important organisms as well as model organisms for biomedical research. Recently, cases of infection of the widely used animal model Danio rerio, commonly known as the zebrafish, by the newly described microsporidium Pseudoloma neurophilia have been reported in an increasing number of research facilities. Current knowledge of the biology of this parasite found in 75% of the Zebrafish Resource Center facilities is limited to microscopic analyses on its lifecycle as well as its physical, behavioral and psychic impact on its hosts. Despite the growing relevance of this parasite in biomedical research no current data is available on its genome. In this dissertation, I provide additional knowledge on the basic biology of P. neurophilia by acquiring and exploring the content and structure of the first genome draft of the zebrafish parasite. My findings reveal that the 5.25 Mb genome of P. neurophilia harbors an unusually high amount of transposable elements as well as numerous inserts found in coding regions typically conserved in microsporidia and other organisms. This peculiar obligate parasite demonstrates strong phylogenetic and genetic relationships with other fish-mosquito microsporidia. Similar to what is observed in closely related species, intra-genomic analyses of P. neurophilia’s genome suggest that it is diploid and possesses a large repertoire of over a thousand putative genes unique to this specie. Overall, my findings provide new insights into the basic biology of this parasite and represent a milestone in the understanding of P. neurophilia and D. rerio host-parasite interaction and ultimately in the development of treatments against this parasite that has been infecting the zebrafish research industry for the past decades.

description: Now you see (through) me: A modular vanadium redox flow cell is used to examine electrolyte distributions in carbon electrodes by synchrotron X‐ray imaging. The impact of three different flow geometries on the flow dynamics is studied, and electrochemical characterizations are concurrently performed with X‐ray imaging to visualize the hydrogen evolution. The unique capabilities of this cell design and experiments are outlined. The wetting behavior and affinity to side reactions of carbon‐based electrodes in vanadium redox flow batteries (VRFBs) are highly dependent on the physical and chemical surface structures of the material, as well as on the cell design itself. To investigate these properties, a new cell design was proposed to facilitate synchrotron X‐ray imaging. Three different flow geometries were studied to understand the impact on the flow dynamics, and the formation of hydrogen bubbles. By electrolyte injection experiments, it was shown that the maximum saturation of carbon felt was achieved by a flat flow field after the first injection and by a serpentine flow field after continuous flow. Furthermore, the average saturation of the carbon felt was correlated to the cyclic voltammetry current response, and the hydrogen gas evolution was visualized in 3D by X‐ray tomography. The capabilities of this cell design and experiments were outlined, which are essential for the evaluation and optimization of cell components of VRFBs.

I’m talking about the residue of the street that builds up on the soles of your feet, the dust and fumes that irritate the mucous membrane, the seduction of the olfactory imagination with the aromas of grimy restaurant exhaust fans, caressing the air with the spunk of a dozen promiscuous cuisines.

description: Background: The epidemiology and risk factors for hepatitis C virus (HCV) infection in Rwanda are not well known; however, this information is crucial to shaping the country’s public health approach to hepatitis C control. Methods: A HCV screening campaign was conducted in the general population in 24 districts previously identified to have a high HCV disease burden. At the time of sample collection, sociodemographic information and self-reported risk factors were collected. Bivariate and multivariate logistic regressions were conducted to assess risk factors independently associated with hepatitis C antibodies (HCVAb) seroprevalence. Results: Out of a total of 326,263 individuals screened for HCVAb, 22,183 (6.8%) were positive. In multivariate analysis, risk factors identified as statistically associated with HCVAb Seroprevalence include history of traditional operation or scarification (OR = 1.09, 95% CI: 1.05–1.14), presence of viral hepatitis in the family (OR = 1.27, 95% CI: 1.15–1.40), widowed or separated/divorced (OR = 1.36, 95% CI: 1.26–1.47), Southern province (OR = 1.98, 95% CI: 1.88–2.08) and aged 65 years and older (OR = 4.86, 95% CI: 4.62–5.11). Ubudehe category 3 (OR = 0.97, 95% CI: 0.93–1.01) and participants using RAMA (Health insurances for employees of public and private sectors) insurance (OR = 0.76, 95% CI: 0.70–0.85) had lower odds of HCV seroprevalence. Conclusions: Our findings provide important information for Rwanda’s strategy on prevention and case-finding. Future prevention interventions should aim to reduce transmission through targeted messaging around traditional healing practices and case-finding targeting individuals with a history of exposure or advanced age.
CLINICAL, LABORATORY AND INSTRUMENTAL FEATURES OF ACUTE OBSTRUCTIVE BRONCHITIS IN FREQUENTLY ILL CHILDREN

description: The share of frequently ill children on average accounts for up to 70-85% of all cases of respiratory diseases in children (1,5,6).  Recent studies have shown that bronchopulmonary diseases often develop against the background of a violation of the normal functioning of the immune system, and in some cases of immunodeficiency states - primary and secondary. Consequently, immunotherapy plays an important role in the therapeutic tactics of obstructive bronchitis (2,3,7).
title: Designing and Decoding Chemical Bonds: A Computational Pipeline Backed Up by Magnetic Criteria and Experiment
Creators: name: Fedik, Nikita

description: You may find plenty of definitions of chemistry but all of them, explicitly or not, are centered around chemical bonds. When we say “chemical properties”, “reactivity”, “stability”, “structure” etc., we have in mind chemical bonds and their reorganization which almost completely defines the behavior of the matter. Why some materials are ultrahard and can cut through steel while others are so soft that you can form them with your bare hands? You probably have already guessed that it occurs because their chemical bonding is very different. Although the elemental composition could be the same! In this Dissertation, we report results which might seem eclectic at first but under the hood all of them are closely related. They employ paradigms of chemical bonding to design new species and decode bonds of already known ones to furtherly advance our knowledge. We discuss design and synthesis of NaBH3-, a first exotic cluster with Na- bonded to neutral BH3 fragment; design and experimental confirmation of B2Al3-, a cluster exhibiting triple B-B bond; delocalized bonds (known as aromaticity) and their transformation in Au clusters; expansion of the same concept of delocalized bonding to 2D semiconducting materials; and finally, a special case of mechanical bond, when stability of two interlocked molecular rings provides the state known as kinetic trap.

Algorithms for acoustic echo cancellation in the presence of double talk.

description: Acoustic echo cancellation is an attractive way to enhance speech quality and provide a full-duplex communication channel for hands-free telephony. Among the many implementation challenges, the problem of "double talk" is considered one of the toughest. When near-end speech and the acoustic echo of the far-end speech are simultaneously present in the microphone signal, it is very difficult to separate these two components and provide satisfactory echo attenuation. After providing a thorough overview of the application and the major adaptive filtering algorithms used in echo cancellation, this thesis presents an in-depth study of the published techniques for dealing with double talk. We classify these existing approaches according to their underlying methodology, such as signal level comparison, signal correlation, weight progression monitoring, and dual filter architecture. The strengths and weaknesses of a number of representative algorithms are discussed in some detail. We argue that detection of echo path changes yields a more robust echo canceller than direct double talk detection. The major contribution of this thesis is the development of a novel variable step size approach that uses a measure of the correlation between successive gradient estimates to control the system's adaptation rate. Two main algorithms, denoted GC-VSS3 and PC-VSS, are derived by applying this approach to the Least Mean Squares and Affine Projection algorithms, respectively. We demonstrate the superior performance of the proposed algorithms in a double talk environment. This is done through a series of simulation experiments using white noise, coloured noise, and recorded speech as the input signals. We also show how an auxiliary double talk detector, based on the proposed variable step size technique, may be employed to control the peripheral echo suppression components that are usually required in a hands-free telephone set. Finally, computational complexity is analyzed and shown to be reasonable for practical implementation when certain beneficial properties of the adaptive filter structure are exploited.
Being other-wise: a tribute to the late Christopher Newell
Creators: name: Morsillo, Robert

description: This brief memoir is a personal tribute to the late Rev Canon Dr Christopher Newell AM (1964 - 2008). Being the fourth year of the TJA prize in his honour, and nearly five years since Christopher’s unfortunate death, it seemed timely to again reflect on our relationship and the seminal contribution and challenge, as a person with disability, that Christopher made to the telecommunications industry and to inclusive customer service. I hope this will provide further insight into Christopher’s role and modus operandi as an agent of change; how he characterised himself as a “critical friend” of the industry yet chose to enter into deep personal relationships with people who walked with him as he scooted along on his journey. In Christopher I found a deep conjunction of the personal and the professional, a priest and a professor, a saint and a rogue.
