description: Background During the first stages of development human infants are either fed human milk or human milk substitutes (infant formulas). The composition of infant formulas and human milk differ drastically, including a difference in protein constituents and bacterial load. Due to the high global frequency of infant formula use, the humanization of infant formulas to better reflect the complex nature of human milk is warranted. To better understand the role of human milk components, the fate and function of a key bacterial sensor in human milk, soluble CD14, was determined. Additionally, the microbiome of human milk was analyzed from a metagenomic standpoint in an attempt to determine which types of bacteria are present in human milk and what their potential biological function might be. Results In rodent models, ingested sCD14 persisted in the gastrointestinal tract and was transferred intact into the blood stream. Once transferred to the blood, ingested sCD14 retained its ability to recognize lipopolysaccharide and initiate an immune response in pups. This transfer of sCD14 across the epithelial barrier was also observed in human cells in vitro, where it appears to be dependent on Toll-like receptor 4. Using Illumina sequencing and the MG-RAST pipeline, the human milk metagenome of ten mothers was sequenced. DNA from human milk aligned to over 360 prokaryotic genera, and contained 30,128 open reading frames assigned to various functional categories. The DNA from human milk was also found to harbor immune-modulatory DNA motifs that may play a significant role in immune development of the infant. Conclusions Given the complex nature of human milk in comparison to its bovine or plant based substitutes, the results presented in this thesis warrant future modification of infant formulas to include non-nutritive bioactive components. Current human milk components not yet present in infant formulas include the diverse microbiome of human milk, the immune-modulatory DNAs which those microbes harbor, and bioactive human proteins such as sCD14.

description: Numerical simulations are presented for three dimensional viscous incompressible free shear flows. The numerical method is based on solving the vorticity equation using Vortex-In-Cell method. In this method, the vorticity field is discretized into a finite set of Lagrangian elements (particles) and the computational domain is covered by Eulerian mesh. Velocity field is computed on the mesh by solving Poisson equation. The solution proceeds in time by advecting the particles with the flow. Second order Adam-Bashford method is used for time integration. Exchange of information between Lagrangian particles and Eulerian grid is carried out using the M’4 interpolation scheme. The classical inviscid scheme is enhanced to account for stretching and viscous effects. For that matter, two schemes are used. The first one used periodic remeshing of the vortex particles along with fourth order finite difference approximation for the partial derivatives of the stretching and viscous terms. In the second scheme, derivatives are approximated by least squares polynomial. The novelty of this work is signified by using the moving least squares technique within the framework of the Vortex-in-Cell method and implementing it to a three dimensional temporal mixing layer. Comparisons of the mean flow and velocity statistics are made with experimental studies. The results confirm the validity of the present schemes. Both schemes also demonstrate capability to qualitatively capture significant flow scales, and allow gaining physical insight as to the development of instabilities and the formation of three dimensional vortex structures. The two schemes show acceptable low numerical diffusion as well.

description: The goal of this thesis was to evaluate the cost-effectiveness of implantable Doppler technology (IDT) used to monitor free tissue transfer (FTT) procedures in the treatment of cancer of the upper aerodigestive tract (UADT). First, a systematic review of the literature on the effectiveness of traditional and IDT monitoring techniques was performed. Second, a utility survey using a time trade-off technique was created and administered. The results from this survey were used to establish utility values for health states common in patients undergoing FTT procedures. Third, a cost study using the microcosting data available through the Ottawa Hospital was performed. Finally, a decision analytic model was created and an economic evaluation from the payer perspective was completed. A probabilistic sensitivity analysis (PSA) and a value of information analysis (VOI) were performed. The thesis found that the currently available evidence supports IDT as a cost-effective intervention. Further research should be directed towards determining the effectiveness of both traditional and IDT monitoring.

description: The purpose of this paper is to present the findings of a study examining the roles and behaviours of boundary spanning managers during the evolutionary stages of the development of public-private partnerships (PPPs). It responds to recent calls in the literature to pursue research that incorporates the pivotal contribution of individual actors in the collaborative process, and to set tills research within the stage specific context of partnerships as they typically proceed through various stages of development. Using a grounded methodology of data collection, coding and analysis within ten Australian and UK PPPs, the study demarcates a five-stage evolutionary development process of PPPs. Within each stage there exists a specific managerial focus in conjunction with one or two main managerial challenges. Boundary-spanning managers employ various strategies to overcome such challenges within each specific stage thus ensuring the progressive evolution of the PPP from one stage to the next, eventually culminating in the successful closure of the project.

description: There is an increasing need for tuneable spectrally pure semiconductor laser sources as well as broadband and polarization insensitive semiconductor optical amplifiers based on the InGaASP/InP material system, to be monolithically integrated with other active and passive components in a photonic integrated circuit. This thesis aims to contribute to finding a solution through modelling, experimental characterization and design improvements. In this thesis we have analyzed laterally-coupled distributed feedback (LC-DFB) lasers. These lasers have the gratings etched directly out of the ridge sidewalls thus lowering the cost associated with the re-growth process required if the gratings were otherwise embedded above the active region. The performance characteristics are analyzed for the LC-DFB lasers partitioned into 1-, 2-, and 3-, electrodes with individual bias control at various operating temperatures. The laser exhibits a stable single mode emission at 1560 nm with a current tuning rate of ~14 pm/mA for a tuning of 2.25 nm. The side modes are highly suppressed with a maximum side-mode suppression ratio of 58 dB. The light-current characteristics show a minimum 40 mA threshold current, and power saturation occurring at higher injection currents. The linewidth characteristics show a minimum Lorentzian linewidth of 210 kHz under free-running and further linewidth reduction under feedback operation. The multi-electrode LC-DFB laser devices under appropriate and selective driving conditions exhibit a flat frequency modulation response from 0 to above 300 MHz. The multi-electrode configuration can thus be further exploited for certain requirements. Simulation results and design improvements are also presented. The experimental characterization of semiconductor optical amplifier (SOA) and Fabry-Perot (FP) laser operating in the E-band are also presented. For the SOA, the linear vertical and horizontal states of polarization corresponding to the transverse electric (TE) and transverse magnetic (TM) modes were considered. For various input power and bias, performance characteristics shows a peak gain of 21 dBm at 1360 nm, gain bandwidth of 60 nm and polarization sensitivity of under 3 dB obtained for the entire wavelength range analyzed from 1340 to 1440 nm. The analysis presented in this thesis show good results with room for improvement in future designs.

description: Fumonisin B1 (FB1), which is emerged by contamination of corn and similar products with Fusarium species, causes a high risk for human and animal health. FB1 shows hepatotoxic, nephrotoxic, neurotoxic, immunotoxic and teratogenic effects. FB1 has also been linked to carcinogenesis processes that are unrelated to genotoxic pathways. Our goal was to investigate the role of gene-specific DNA methylation and expression of tumour suppressor genes in the toxicity of FB1 in human kidney (HK-2) cells. Using array panels, effects of FB1 exposure (10-100 μM) for 24 h on methylation levels of tumour suppressor genes were investigated. ToppGene Suite (Toppfun) portal was used to perform gene ontology (GO), Kyoto Encyclopedia of Genes and Genomes pathway (KEGG) and Reactome enrichment studies. The most of the genes were hypermethylated significantly at 100 μM concentrations of FB1. These results are consistent with the expression results which downregulate the selected genes of CD44, CDKN1A, CDKN2B, CTNNB1, MYC and p16. Functional enrichment analysis further elucidated the molecular mechanisms of FB1 in cancer-related pathways especially p53 signalling and PI3K/Akt signaling. It has been expected that the present study could contribute to the studies on the mechanisms that play a role in FB1 induced carcinogenesis.

description: Focusing on communication as an important means besides other efforts for conflict resolution in an asymmetric armed conflict in Afghanistan, this study looked for a rhetorical communication approach appropriate to Pashtun tribal setting in South-eastern (Loya Paktya region) Afghanistan. The study explored and found some perceived essentials of such persuasive communication by conducting face-to-face semi-structured in depth interviews with 17 participants. Thematic analysis was used to code and categorize data. Aristotle’s rhetorical theory provided a framework for this qualitative study by narrowing down the focus to exploring credibility of the communicator (ethos), the rationality of the message (logos), and the emotional appeals (pathos), particular for the south-eastern Pashtun tribal setting, during communication. In addition, considering the relation between rhetorical and soft power theories in influencing the choice of an audience, this project also asked participants if and how communication in their tribal setting could be framed as an influencing power by attraction rather than by coercion. Therefore, soft power of which persuasive communication is a crucial part was also used as a theoretical framework for this study. The findings show the significance of persuasive communication in future conflict resolution efforts in Afghanistan.

description: For a number of years, Canadian immigration selection policy has deliberately emphasized the human capital characteristics of applicants in determining admissibility for permanent residence. Largely due to these measures, Chinese immigrants today are overwhelmingly well-educated and skilled. This thesis examines the role of geography in shaping Chinese newcomers’ post-arrival employment status, with an emphasis on working in the high-tech sector. Given that Ottawa is a leading node of high-tech employment in Canada, this project initially investigates the probability that Chinese newcomers will work in the high-tech sector in Ottawa-Gatineau relative to other cities. The project subsequently examines the degree to which employment in the high-tech sector in Ottawa-Gatineau is related to ethnic, social and demographic characteristics of local spaces where people live and work. All aspects of the study adopt a gender lens with respect to interpreting employment status. The study finds that Chinese immigrants in Ottawa-Gatineau are more likely to work in this sector than their counterparts in Vancouver and Toronto. They are also more likely to work in high-tech relative to individuals in other immigrant groups or the Canadian-born population. With respect to co-ethnic residential and work spatial configurations, as well as social and demographic characteristics of residential neighbourhoods, the study finds that these factors exert quite different influences on the likelihood that Chinese women and men will work in Ottawa-Gatineau’s high-tech sector. The results are quite distinctly different for women and men, and underline the importance of a gendered analysis of relationships between geographic location/place and employment status.

description: La sociologie a proposé une multitude d’explications sur divers phénomènes sociaux. Cependant, plusieurs sociologues, dont Boudon se sont surtout intéressés à l’aspect scientifique de la sociologie. Les questions les plus souvent posées lorsqu’on entreprend de telles études se penchent essentiellement sur le caractère scientifique de la discipline sociologique. Quels sont les critères de scientificité de la sociologie ? Quel est son sens épistémologique dans la littérature scientifique ? Quel est son raisonnement existentiel dans la construction du savoir ? La sociologie pourrait-elle être traitée méthodologiquement parlant au même titre que les autres disciplines des sciences naturelles ou particulières ? Si oui, pourrait-elle expliquer les lois des phénomènes sociaux à partir des observations hypothético-déductives sur la nature de la réalité sociale ? Dans cette thèse, nous tenterons de répondre à ces questions en nous appuyant sur des concepts élaborés par les sociologues classiques et contemporains.

Subjects: coach learning

description: The purpose of the present study was to explore the influence of an NCCP coach education module on coaches‟ ongoing learning. Using the theoretical framework of Jarvis (2006) and Moon (2004) to guide the research, this study consisted of three phases: an interview with each of the 10 coaches prior to attending a module to understand their biographies as well as various learning situations they had already experienced; attendance at one of three potential Competition-Development modules, Managing Conflict, Coaching and Leading Effectively, or Psychology of Performance, and an interview with each of the 10 coaches immediately following the module to explore their thoughts, reflections and possible learning within the module; and a third and final interview with each of the 10 coaches three months following the module to explore how they implemented learning from the module, as well as other learning situations that may have occurred within that 3 month timeframe. The findings indicated that the biographies of each of the coaches varied considerably. For example, the coaches‟ athletic experiences ranged from recreational to national level and several of the coaches were still active in sport at a master‟s level. Their formal education levels ranged from high school to completion of a university masters degree, and their ages varied from 21-45. As well, each of the coaches said they learned something from the NCCP coaching module they attended such as a more effective method for communicating with their athletes, strategies to cope better with conflict, and the importance of setting a variety of goals. The findings also indicated that a number of the coaches were open to on-going learning and stated that they would continue to enrol in formal coach education modules.

description: A stochastic leaky integrate-and-fire neuron model was implemented in this study to simulate the spiking activity of the electrosensory "P-unit" receptor neurons of the weakly electric fish Apteronotus leptorhynchus. In the context of sensory coding, these cells have been previously shown to respond in experiment to natural random narrowband signals with either a linear or nonlinear coding scheme, depending on the intrinsic firing rate of the cell in the absence of external stimulation. It was hypothesised in this study that this duality is due to the relation of the stimulus to the neuron's excitation threshold. This hypothesis was validated with the model by lowering the threshold of the neuron or increasing its intrinsic noise, or randomness, either of which made the relation between firing rate and input strength more linear. Furthermore, synchronous P-unit firing to a common input also plays a role in decoding the stimulus at deeper levels of the neural pathways. Synchronisation and desynchronisation between multiple model responses for different types of natural communication signals were shown to agree with experimental observations. A novel result of resonance-induced synchrony enhancement of P-units to certain communication frequencies was also found.
Attitudes to abortion in Australia: 1972 to 2003

description: Since the October 2004 Federal election Australia has embarked on a new abortion debate. Some commentators suggest that public opinion has turned away from a pro-choice position. However the new 2003 Australian Survey of Social Attitudes shows this is not so: 81 per cent of Australians are pro-choice and only nine per cent are definitely anti-choice. This and other surveys show that the only strong constituencies for change are among some evangelical Christians and some Coalition candidates in Federal elections. Women of child-bearing age are overwhelmingly pro-choice.

description: We report the first secondary metabolite, 8,8′-bijuglone, obtained from pure cultures of the slow growing Douglas fir- (Pseudotsuga menziesii var. menziesii) foliage-associated fungus Zasmidium pseudotsugae. The quinone was characterized using extensive LC/MS and NMR-based spectroscopic methods. 8,8′-Bijuglone exhibited moderate antibiotic activity against Gram-positive pathogens and weak cytotoxic activity in the NCI-60 cell line panel and in our in-house human colon carcinoma (HCT-116) cell line. An analysis of the fungal genome sequence to assess its metabolic potential was implemented using the bioinformatic tool antiSMASH. In total, 36 putative biosynthetic gene clusters were found with a majority encoding for polyketides (17), followed by non-ribosomal peptides (14), terpenes (2), ribosomal peptides (1), and compounds with mixed biosynthetic origin (2). This study demonstrates that foliage associated fungi of conifers produce antimicrobial metabolites and suggests this guild of fungi may present a rich source of novel molecules.

description: This thesis presents two modern control methods to address the Internet traffic congestion control issues. They are based on a distributed traffic management framework for the fast-growing Internet traffic in which routers are deployed with intelligent or optimal data rate controllers to tackle the traffic mass. The first one is called the IntelRate (Intelligent Rate) controller using the fuzzy logic theory. Unlike other explicit traffic control protocols that have to estimate network parameters (e.g., link latency, bottleneck bandwidth, packet loss rate, or the number of flows), our fuzzy-logic-based explicit controller can measure the router queue size directly. Hence it avoids various potential performance problems arising from parameter estimations while reducing much computation and memory consumption in the routers. The communication QoS (Quality of Service) is assured by the good performances of our scheme such as max-min fairness, low queueing delay and good robustness to network dynamics. Using the Lyapunov’s Direct Method, this controller is proved to be globally asymptotically stable. The other one is called the OFEX (Optimal and Fully EXplicit) controller using convex optimization. This new scheme is able to provide not only optimal bandwidth allocation but also fully explicit congestion signal to sources. It uses the congestion signal from the most congested link, instead of the cumulative signal from a flow path. In this way, it overcomes the drawback of the relatively explicit controllers that bias the multi-bottlenecked users, and significantly improves their convergence speed and throughput performance. Furthermore, the OFEX controller design considers a dynamic model by proposing a remedial measure against the unpredictable bandwidth changes in contention-based multi-access networks (such as shared Ethernet or IEEE 802.11). When compared with the former works/controllers, such a remedy also effectively reduces the instantaneous queue size in a router, and thus significantly improving the queueing delay and packet loss performance. Finally, the applications of these two controllers on wireless local area networks have been investigated. Their design guidelines/limits are also provided based on our experiences.

description: Loss aversion is a central component of Prospect Theory (Kahneman & Tversky, 1979). It describes a decision maker’s tendency to prefer avoiding losses to acquiring equivalent gains. Decades of research on Prospect Theory have produced compelling evidence of loss aversion. However, the vast majority of this evidence emerges from laboratory experiments, and only few studies examine field evidence of loss aversion. In particular, loss aversion is rarely studied in “real” financial decisions.

This study uses hand collected data from a German TV show (“Bares für Rares”) to investigate loss aversion in real financial decisions. In this show, an applicant (“the seller”) can auction off a curiosity, rarity, or antique to professional antique dealers (“the buyers”). The show is divided in two parts. In the first part of the show the seller meets an expert who evaluates the good for sale. If the seller agrees with the value determined by the expert, the item is auctioned off to the buyers in the second part of the show.

To analyze sellers’ loss aversion, we investigate whether the willingness to sell (i.e. the willingness to accept a bid) depends on the relation between the highest bid and the prize estimate provided by the expert (the reference point). Our main hypothesis is that sellers are substantially less likely to sell when the bid is below the prize estimate than when the bid is equal to or above the prize estimate. Similarly, we assume that sellers are more likely to ask for a higher bid when the current bid is below the prize estimate.

description: This thesis focuses on video watermarking robust against geometric attacks and video compressions. In addition to the requirements for an image watermarking algorithm, a digital video watermarking algorithm has to be robust against advanced video compressions, frame loss, frame swapping, aspect ratio change, frame rate change, intra- and inter-frame filtering, etc. Video compression, especially, the most efficient compression standard, H.264, and geometric attacks, such as rotation and cropping, frame aspect ratio change, and translation, are considered the most challenging attacks for video watermarking algorithms. In this thesis, we first review typical watermarking algorithms robust against geometric attacks and video compressions, and point out their advantages and disadvantages. Then, we propose our robust video watermarking algorithms against Rotation, Scaling and Translation (RST) attacks and MPEG-2 compression based on the logpolar mapping and the phase-only filtering method. Rotation or scaling transformation in the spatial domain results in vertical or horizontal shift in the log-polar mapping (LPM) of the magnitude of the Fourier spectrum of the target frame. Translation has no effect in this domain. This method is very robust to RST attacks and MPEG-2 compression. We also demonstrate that this method can be used as a RST parameters detector to work with other watermarking algorithms to improve their robustness to RST attacks. Furthermore, we propose a new video watermarking algorithm based on the 1D DFT (one-dimensional Discrete Fourier Transform) and 1D projection. This algorithm enhances the robustness to video compression and is able to resist the most advanced video compression, H.264. The 1D DFT for a video sequence along the temporal domain generates an ideal domain, in which the spatial information is still kept and the temporal information is obtained. With detailed analysis and calculation, we choose the frames with highest temporal frequencies to embed the fence-shaped watermark pattern in the Radon transform domain of the selected frames. The performance of the proposed algorithm is evaluated by video compression standards MPEG-2 and H.264; geometric attacks such as rotation, translation, and aspect-ratio changes; and other video processing. The most important advantages of this video watermarking algorithm are its simplicity, practicality and robustness.
Cultural institutions, co-creativity and communities of interest

description: Despite the proliferation of web-based news and information services, there remains a lack of online destinations from which to obtain reliable and authoritative cultural knowledge. In many countries, such knowledge is provided by cultural institutions such as museums and libraries. Recent discussion suggests that social media – including blogs, wikis and digital stories – may provide a creative solution to the ongoing interaction between cultural institutions and communities of interest. However, little applied research exists to demonstrate how social media can be established and maintained within museums and libraries, and what issues are raised within the institution by a more participatory approach to cultural communication. This paper highlights the implementation of a new program at the Australian Museum to train staff in social media production, in order to make the many thousands of objects and stories held within the Museum’s collections more accessible and engaging to communities of interest.
“The West Side Story”: Urban Communication and the Social Exclusion of the Hazara People in West Kabul

description: Within the framework of urban communication, this thesis attempts to "read" the urban space of West Kabul in Afghanistan, as a social and cultural text in order to understand the social exclusion of the Hazara people, a socially and politically disenfranchised ethnic group who predominantly inhabit that area. Based on data gathered through documentary research and non-participant field observations, this thesis argues that the urban space of West Kabul is the spatial manifestation of a systematic exclusionary process, through which, the Hazara people have been deprived from access to political, economic and cultural resources, services and opportunities. It interprets the city planning, distribution of resources, urbicide, streetscape, architecture and the body as the main sites where the social exclusion of the Hazaras in West Kabul is exercised. This study also provides a discussion about the historical evolution of West Kabul as an ethnic ghetto, as well as the various forms of conflict which led to spatial and social division in Kabul city.
Workforce development for research software engineers in plasma science

Year: 2024

description: Research software engineers (RSEs) encompass researchers who spend a lot of their time coding, software engineers who focus on research software, and everyone in between. While the term was only coined in the prior decade, RSEs have played vital roles in plasma and fusion energy sciences for decades. Despite the importance of RSEs, there are limited pathways for becoming an RSE in our field and often an unclear career path. This presentation will cover the need for workforce development for RSEs in our community, and describe efforts in our field and others to cultivate and support an RSE workforce.

description: Recently there has been interest in determining what happens to the human brain during a traumatic brain injury (TBI). The blast wave created by explosive devices, such as landmines, is one of the most common causes of TBI. The purpose of this study is to investigate the link between an explosion and a cells reaction to a blast wave on a time scale of a few hours. Three different types of cells were tested by pressure waves exposure, fibroblasts (3T3), epithelial cervical cancer (HeLa), and canine epithelial kidney cells (MDCK). Fluorescent images of the cells before and after pressure wave exposure were used to determine how much damage cells have suffered. 3T3 cells showed the most cellular modification while HeLa and MDCK were more resilient. A simple scaling model is proposed to relate the cellular modification to the shock strength.
Body and Capital: Underprivileged Women's Relation with Health and Obesity

description: Drawing from Pierre Bourdieu’s socio-cultural approach, this qualitative research project aimed to: (a) understand the responses to current body norms and expectations tied to health and physical appearances amongst underprivileged young women; and; (b) understand to what extent the dominant obesity discourse is inscribed in these women’s bodily habits. Results highlight that participants were aware of the dominant obesity discourse through their perceptions, sentiments, and dispositions towards bodily norms and expectations. Despite their awareness, underprivileged living conditions generated other sets of priorities, such as motherhood, achieving economic stability, completing education, and gaining physical independence which were far greater preoccupations. Underprivileged young women’s ‘choice of the necessary’ is based on optimizing resources and prioritizing needs and responsibilities. Findings support the use of Pierre Bourdieu’s concepts which consider the effects of various aspects of underprivileged living conditions on lifestyles.

description: Palladium-catalyzed reactions for carbon-carbon bond formation have had a significant impact on the field of organic chemistry in recent decades. Illustrative is the 2010 Nobel Prize, awarded for “palladium-catalyzed cross couplings in organic synthesis”, and the numerous applications of these transformations in industrial settings. This thesis describes recent developments in C(sp2)-C(sp3) bond formation, focusing on alkane arylation reactions and arylative dearomatization transformations. In the first part, our contributions to the development of intramolecular C(sp3)-H arylation reactions from aryl chlorides are described (Chapter 2). The use of catalytic quantities of pivalic acid was found to be crucial to observe the desired reactivity. The reactions are highly chemoselective for arylation at primary aliphatic C-H bonds. Theoretical calculations revealed that C-H bond cleavage is facilitated by the formation of an agostic interaction between the palladium centre and a geminal C-H bond. In the following section, the development of an alkane arylation reaction adjacent to amides and sulfonamides is presented (Chapter 3). The mechanism of C(sp3)-H bond cleavage in alkane arylation reactions is also addressed through an in-depth experimental and theoretical mechanistic study. The isolation and characterization of an intermediate in the catalytic cycle, the evaluation of the roles of both carbonate and pivalate bases in reaction mechanism as well as kinetic studies are reported. Our serendipitous discovery of an arylation reaction at cyclopropane methylene C-H bonds is discussed in Chapter 4. Reaction conditions for the conversion of cyclopropylanilines to quinolines/tetrahydroquinolines via one-pot palladium(0)-catalyzed C(sp3)-H arylation with subsequent oxidation/reduction are described. Initial studies are also presented, which suggest that this transformation is mechanistically unique from other Pd catalyzed cyclopropane ring-opening reactions. Preliminary investigations towards the development of an asymmetric alkane arylation reaction are highlighted in Chapter 5. Both chiral carboxylic acid additives and phosphine ligands have been examined in this context. While high yields and enantiomeric excesses were never observed, encouraging results have been obtained and are supported by recent reports from other research groups. Finally, in part two, the use of Pd(0)-catalysis for the intramolecular arylative dearomatization of phenols is presented (Chapter 7). These reactions generate spirocyclohexadienones bearing all-carbon quaternary centres in good to excellent yields. The nature of the base, although not well understood, appears to be crucial for this transformation. Preliminary results in the development of an enantioselective variant of this transformation demonstrate the influence of catalyst activation on levels of enantiomeric excess.
