Schedule sensitivity of instructed human operant behaviour: Effects of warning and of social stimuli with elaborate and minimal instructions.
Creators: name: Boisvert, Christine-Shawn.
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 1999
Subjects: subject: Psychology, Behavioral.

description: Schedule insensitivity of behaviours that are established through elaborate instructions is a frequently reported finding in the behavioural literature. This insensitivity usually takes one of two forms: (a) behaviour pattern that is not appropriate to the schedule in effect or (b) failure of the behaviour pattern to adjust once a new unannounced schedule is put in effect. However, a number of methodological flaws in previously published studies hinder a clear interpretation of these findings. The current series of studies attempted to rectify these problems by including sufficiently large groups of subjects (n = 14 or 15) to allow for acceptable levels of power. In addition, the same experimental task was used throughout to provide continuity. This task involved first establishing steady-state responding on a multiple DRL6s/FR18 schedule, and then changing the parameters of the schedule, without alerting subjects to this change. Experiment 1 attempted to replicate the previous findings that indicated that elaborate instructions induced schedule insensitivity when the multiple schedule was changed to EXT/EXT. Experiment 2 investigated the generalisability of the findings of Experiment 1 by examining the effect of a change in contingency to FR18/FR18. Experiments 3 and 4 investigated whether the findings of the first two studies were due to the effect of a "social variable" (the salience of the social stimuli). Experiments 1, 2, and 3 also investigated the effect of a "warning" that conditions may change at any tune. Overall, the results suggest that the warning decreases the schedule insensitivity engendered by the elaborate instructions. The results also suggest that the salience of the social stimuli is an important factor in producing the "insensitivity effect," and may be responsible for some of the more dramatic results in the literature. Further, the findings raise the question of whether instructions do, in fact, engender schedule insensitivity.

description: Plastic packaging forms a significant portion of household waste, and PET soft drink bottles represent a major percentage of the waste. Consequently, PET bottle grade material makes up a significant portion of the feedstock in the recycling plant at Visy plastics. The end uses are theoretically many, however, there are few applications for less purified grades of recycled PET. This paper presents the preliminary results of an industry based collaborative research project which aims to investigate the breaking down of recycled PET into its chemical building blocks using glycolysis. The main objective is to produce a polyester polyol for the polyurethane industry from recycled PET and to compare the properties with that of a virgin resin.

description: Affective computing is becoming more and more popular, and the need to find a user-friendly and reliable method of estimating people’s emotions, in their everyday life, is growing. Traditional methods have reached their limits, and this thesis presents a new system of emotion recognition, though physiological signals. With a user-friendly, wearable device, the system can be deployed in a number of fields. A model for our emotion classification is presented and includes the following emotions: cheerfulness, sadness, erotic, horror, and neutral. An experiment of emotion elicitation is also described in this work. Three analysis models applied in our system in order to recognize emotions, including nearest neighbor, discriminant analysis, and multi-layer perception, are discussed in detail. The final test results show that the system has the average recognition rates of 40%, 55.7%, and 77.34% for nearest neighbor, discriminant analysis, and multi-layer perception respectively.

La guerre contre l'écologisme : essor et déclin de la Commission de la conservation du Canada, 1909-1921.

description: Creee par le gouvernement Laurier en 1909, la Commission de la conservation du Canada fut presidee par Clifford Sifton et dirigee par le geographe James White. Entre 1909 et 1921 elle a produit pres de 200 rapports. Ses sept comites permanents (forets; eaux et pouvoirs d'eau; terres; minerais; sante publique; faune et service de presse) ont propose trois objectifs afin d'assurer le developpement durable de l'economie canadienne: elimination du gaspillage dans l'extraction et l'utilisation des ressources non-renouvelables; conservation des ressources renouvelables selon le principe du rendement soutenu et preservation des especes menacees. Les Commissaires ont formule trois strategies pour atteindre ces objectifs: recherche et elaboration de politiques progressistes a l'intention des gouvernements; education des publics par le biais de livres, brochures et periodiques et enfin recherche scientifique et industrielle afin de decouvrir de nouvelles techniques et moyens de production moins dommageables pour l'environnement. La popularite de la Commission a atteint son apogee vers 1914. Mais la premiere Guerre mondiale et la participation active du Canada a l'effort de guerre ont serieusement affectes l'organisme. Les Commissaires ont ete appeles a encourager la production plutot que la conservation et le developpement accelere du potentiel industriel canadien plutot que le developpement durable. La plupart ont ete incapables mettre de cote leurs principes et leurs ideaux d'avant-guerre. Leur manque d'enthousiasme a profite a ceux qui preconisaient l'expansion rapide du potentiel industriel canadien, notamment les membres du Conseil national de recherches du Canada (CNRC). Vers la fin de la Guerre, les ennemis de la Commission se sont multiplies. Le gouvernement Meighen, aux prises avec un deficit budgetaire sans precedent, abolit l'organisme en mai 1921, alors que le Canada traversait un severe recession economique. Cependant, l'interet pour la conservation du milieu naturel ne s'est pas evanoui: une pleiade d'organisations, comme l'Association forestiere canadienne, ont repris le flambeau et ont joui d'un appui significatif aupres de la population. Les realisations de la Commission sont examinees dans le contexte plus large de l'histoire de l'ecologisme en Occident. L'ecologisme, prise de conscience que certaines activites humaines ont un effet nefaste sur l'environnement, a des racines qui remontent dans le temps et qui precedent de loin la naissance de la science de l'ecologie. Une telle interpretation permet de mieux comprendre l'histoire des problemes environnementaux et les defis auxquels sont confrontes des generations d'ecologistes.

description: In Canada alone, there were an estimated 800,000 visually impaired people in 2007, costing the federal government an annual amount of $15.8 billion in services, treatments and lost revenue. These costs are estimated to double by the year 2032, as the population ages. The leading causes of visual impairment and blindness is retinal degeneration, characterized by the progressive death of retinal cells. The research presented in this PhD thesis aimed to prevent retinal degeneration by over-expressing the X-linked Inhibitor of Apoptosis (XIAP) in retinal cells using plasmid and adeno-associated viral vectors. The work is divided into four sequential chapters targeted at developing an anti-apoptotic gene therapy strategy to prevent retinal cell death. The first chapter examines XIAP gene therapy in the treatment of Leber’s Hereditary Optic Neuropathy (LHON). In vitro studies using the 661W cone-photoreceptor cell line showed that XIAP over-expression significantly lowers cell death when 661W cells are exposed to a number of apoptotic stimuli. In a mouse model of Leber’s Hereditary Optic Neuropathy (LHON), XIAP expression in retinal ganglion cells (RGCs) protected the ultrastructure of the RGC axons within the optic nerve, in addition to providing evidence of functional protection. The second and third chapters further examine the potential for XIAP gene therapy in the treatment of retinal disease by developing an in vivo model of retinal detachment in cats, followed by evaluating the efficacy of XIAP gene therapy intervention. When XIAP was over-expressed in the photoreceptor cells, there was significant structural protection and trends in preservation of function in this model of degeneration. Finally, the fourth chapter explores an alternate method to viral gene therapy by evaluating the efficacy and toxicity of chitosan microparticles as a protein delivery system to the retina. Results show that chitosan microparticles are mucosal-adhesive and are non-toxic at low concentrations in vitro in 661W cells and in vivo in rats. This thesis work provides strong evidence that XIAP gene therapy is an effective method for preventing retinal degeneration, and works as a broad spectrum gene therapy strategy that can be applied to different forms of retinal degeneration.

description: Advanced materials, and nanomaterials, are promising for healthcare applications and are in particular in the spotlight of medical innovation since rapidly developed nano-formulated vaccines provide relief in the SARS-CoV-2 pandemic. Further increased rapid growth is to be expected as more and more products are in development and reach the market, beneficial for human health. However, the human body is not a dead end and these products are likely to enter the environment, whereas their fate and effects in the environment are unknown. This part of the life-cycle of advanced medicinal products tends to be overlooked, if the perspective is human-centered and excludes the connectedness of human activity with, and consequences for our environment. Gaps are reviewed that exist in awareness, perspective taking, inclusion of environmental concerns into research and product development and also in available methodologies and regulatory guidance. To bridge these gaps, possible ways forward start to emerge, that could help to find a more integrative way of assessing human and environmental safety for advanced material medicinal products and nanomedicines. © The Author(s) 2022.

description: Abstract Background Continued investment, especially from domestic financing, is needed for Ethiopia to achieve universal health coverage and a sustainable health system over time. Understanding costs of providing health services will assist the government to mobilize adequate resources for health, and to understand future costs of changes in quality of care, service provision scope, and potential decline in external resources. This study assessed costs per unit of service output, “unit costs”, for government primary hospitals and health centers, and disease-specific services within each facility. Methods Quantitative and qualitative data were collected from 25 primary hospitals and 47 health centers across eight of the eleven regions of Ethiopia for 2013/14, and 2014/15 and 2015/16 but only for primary hospitals, and supplemented by other related health and financial institutions records. A top-down costing approach was used to estimate unit costs for each facility by department – inpatient, outpatient, maternal and child health, and delivery. A mixed-method approach was used for the disease-specific unit costs exempt from fees. Results Health center median unit cost was 146 Ethiopian birr (ETB) (17 PPP$, 2012), the Delivery department had the highest median unit cost (647 ETB; 76 PPP$, 2012) and Outpatient department (OPD) had the lowest (124 ETB; 14 PPP$, 2012). Primary hospital median unit cost was 339 ETB (40 PPP$, 2012), with Inpatient department having the highest median unit cost (1288 ETB; 151 PPP$, 2012), while OPD was the lowest (252 ETB; 29 PPP$, 2012). Drugs and pharmaceutical supplies accounted for most of the costs for both facilities. Among the exempted services offered, tuberculosis and antiretroviral treatment are the costliest with median unit costs from 1091 to 1536 ETB (128–180 PPP$, 2012), with drugs and supplies accounting for almost 90% of the costs. Conclusions High unit costs of service provision could be indicative of underutilization of the primary health care system, coupled with inefficiencies associated with organization and delivery of health services. Data from this study are being used to assess efficiency and productivity among primary care facilities, facilitate premium setting for health insurance, and improve budgeting and allocating health resources for a more sustainable and effective primary health care system.

description: Data Drift is the phenomenon where the generating model behind the data changes over time. Due to data drift, any model built on the past training data becomes less relevant and inaccurate over time. Thus, detecting and controlling for data drift is critical in machine learning models. Hierarchical Temporal Memory (HTM) is a machine learning model developed by Jeff Hawkins, inspired by how the human brain processes information. It is a biologically inspired model of memory that is similar in structure to the neocortex, and whose performance is claimed to be comparable to state of the art models in detecting anomalies in time series data. Another unique benefit of HTMs is its independence from training and testing cycle; all the learning takes place online with streaming data and no separate training and testing cycle is required. In sequential learning paradigm, Sequential Probability Ratio Test (SPRT) offers some unique benefit for online learning and inference. This paper proposes a novel hybrid framework combining HTM and SPRT for real-time data drift detection and anomaly identification. Unlike existing data drift methods, our approach eliminates frequent retraining and ensures low false positive rates. HTMs currently work with one dimensional or univariate data. In a second study, we also propose an application of HTM in multidimensional supervised scenario for anomaly detection by combining the outputs of multiple HTM columns, one for each dimension of the data, through a neural network. Experimental evaluations demonstrate that the proposed method outperforms conventional drift detection techniques like the Kolmogorov-Smirnov (KS) test, Wasserstein distance, and Population Stability Index (PSI) in terms of accuracy, adaptability, and computational efficiency. Our experiments also provide insights into optimizing hyperparameters for real-time deployment in domains such as Telecom.

description: The thesis examines how the social construction of African women in development discourse transformed from the 1970s to the 2000s, focusing in particular on the Canadian International Development Agency (CIDA). From the 1970s to the 1990s representations of African women were based on women’s economic potential. The mainstreaming of gender in the 1990s resulted in women being represented as agents of change. This approach gave women an opportunity to play roles in decision-making but led to policies that failed to challenge the established institutions. The emphasis on women as agents of change opened doors to some African women but with implications for the women’s movement. Only some middle-class women appear to benefit but their gains have been marginal in comparison to the gender inequalities that persist. The thesis uses secondary sources and interviews with development practitioners in Ottawa to understand the representation of African women as agents of change.

description: In public debate and academic scholarship, opinion is divided over two connected issues: What are the consequences of 'information poverty' for social cohesion, security and civil peace (Norris 2001, Bowie 2000)? And can new technologies be used to open up government, increase civic participation and rebuild community? While some cultural and media studies scholars continue to celebrate the democratising potential of the Internet, and economic liberals highlight the challenge of relatively unregulated new media, social scientists and policy agencies have pointed to the uneven social, cultural and geographical diffusion of computers, and the potential of technology use to amplify inequalities (DiMaggio & Hargittai 2001), or to fragment political culture (Castells 1996, Giddens & Hutton 2000, Sunstein 2001). This special issue of Southern Review explores these questions. Here we review the main preoccupations in the current debate, focusing on the question of information poverty, its conceptualisation by governments and others, and a variety of strategies devised to address it. In doing so, we highlight the need for further research on current and historical patterns of adaptation and improvisation between technology, government and democratic political rationality. This edited collection stems, in part, from the international conference, Digital Divides: Technology and Politics in the Information Age, held on 22-24 August, at Hong Kong Baptist University, and organised by the Institute for Social Research, Swinburne University of Technology, the David C. Lam Institute for East-West Studies and the Win Lung Bank International Institute for Business Development.

A model analysis of flat slabs.

Year: 1977
Subjects: subject: Engineering, Civil.

description: A two-storey 3 bay x 3 bay, 1/12 scale, perspex flat slab model was tested under a one-bay uniformly distributed load, which was applied successively to the various bays. The load was applied using a rubber air bag. The moments induced in the model were measured by electrical resistance type strain gages and the deflections by dial gages. By analysis of the experimental results, and comparing them with the ACI 318-71 Direct Design Method, the following conclusions were obtained: The total static moment given by the ACI 318-71 Direct Design Method is accurate for all practical purposes. The width of the column strip specified by the ACI Code in Clause 13.1.2 of 0.25 ℓ2 but not greater than 0.25 ℓ1 results in too great a concentration of negative moment in the column strip. This concentration of moment in the column strip is even less justified for the positive moment where the column strip moment/unit width and the middle strip moments/unit width are of approximately equal magnitude. The effect of the concentration of positive moment in the column strip together with aforementioned restriction of the width of the column strip results in middle strip design positive moments 25% less than those measured. The provision "13.3.4.6" that a design moment may be adjusted by up to 10% provided that the total static moment is not less than required should be changed by eliminating the 10% limit. It is recommended that adjustment be applied to the negative moment only. The provisions for the effects of pattern loading "13.3.6" are insufficient. The limitation of live load to dead load ratios stated in "13.3.1.5" results in a possibility of developing negative moments in or near mid span of interior panels.

description: With the increasingly prominent environmental problems and the decline of fossil fuel reserves, the reduction of energy consumption (EC) has become a common goal in the world. Urea industry is a typical energy-intensive chemical industry. However, studies just focus on the breakthrough of specific production technology or only consider the EC in the production stage. This results in a lack of evaluations of the life cycle of energy consumption (LcEC). In order to provide a systematic, scientific, and practical theoretical basis for the industrial upgrading and the energy transformation, LcEC of urea production and the greenhouse gas (GHG) emissions generated in the process of EC are studied in this paper. The results show that the average LcEC is about 30.1 GJ/t urea. The EC of the materials preparation stage, synthesis stage, and waste-treatment stage (ECRMP, ECPP, ECWD) is about 0.388 GJ/t urea, 24.8 GJ/t urea, and 4.92 GJ/t urea, accounting for 1.3%, 82.4%, and 16.3% of LcEC, respectively. Thus, the synthesis stage is a dominant energy-consumer, in which 15.4 GJ/t urea of energy, accounting for 62.0% of ECpp, supports steam consumption. According to the energy distribution analysis, it can be concluded that coal presents the primary energy in the process of urea production, which supports 94.4% of LcEC. The proportion of coal consumption is significantly higher than that of the average of 59% in China. Besides, the GHG emissions in the synthesis stage are obviously larger than that in the other stage, with an average of 2.18 t eq.CO₂/t urea, accounting for 81.3% of the life cycle of GHG (LcGHG) emissions. In detail, CO₂ is the dominant factor accounting for 90.0% of LcGHG emissions, followed by CH₄, while N₂O is negligible. Coal is the primary source of CO₂ emissions. The severe high proportion of coal consumption in the life cycle of urea production is responsible for this high CO₂ content of GHG emissions. Therefore, for industrial urea upgrading and energy transformation, reducing coal consumption will still be an important task for energy structure transformation. At the same time, the reformation of synthesis technologies, especially for steam energy-consuming technology, will mainly reduce the EC of the urea industry. Furthermore, the application of green energy will be conducive to a win-win situation for both economic and environmental benefits.

description: This study on engagement in environmental activism can offer valuable insights into how Ontario’s young people come to be responsible stewards of the earth. This research seeks to understand the narrative complexities put forth by teachers and students (Gr. 11-12) about the influence school plays for environmental activists. The teachers’ involvement with activism is mediated by students and the social networks that support their actions. The students’ involvement in action is influenced by teacher mentors, learning about/in the environment, and having a venue for activism. These findings suggest that in order to live up to Acting Today, Shaping Tomorrow schools should be seeking to have at least one environmentally literate teacher who wants to provide students with a venue for action. To assist the teachers and students with activism, there needs to be support for environmental action initiatives from the school administration and the community.

description: Extensive technological progress is essential to meet the ambitious future requirements of energy storage devices. This is due to the necessity of achieving high energy and power density operations, accompanied by high safety standards and extended lifespans, while maintaining low production and material costs. Significant importance is placed on the research of high energy active materials. However, besides material optimization, there is substantial potential for optimization by introducing electrodes with high mass loading, advanced electrode architectures, and their transfer to production level. Achieving appropriate trade-offs between high energy and power density, process reliability, and economic considerations poses a challenge for current lithium-ion battery technology. For this purpose, the laser-assisted generation of three-dimensional (3D) electrode architectures is studied and evaluated. Advanced electrode design incorporates micro and sub-micron structures that can be designed in various ways. Significant improvements in battery lifespan and high-power operation capabilities can be achieved compared to traditional two-dimensional (2D) electrodes. Furthermore, the production of 3D electrodes with laser processing requires coordination with other established manufacturing steps in the battery production process. In particular, the calendering of electrodes holds great importance as it has a significant impact on the microstructural properties of the composite electrode, including porosity, material density, and film adhesion strength. This study investigated the impact of laser-induced hierarchical structuring, comprising micro-/nano-porosities and microtopography, on electrodes with varying mass loadings from 2 mAh/cm² to 6 mAh/cm². In this regard, cells comprising graphite anodes and lithium-nickel-manganese-cobalt oxide cathodes were prepared and subjected to electrochemical characterization techniques.

description: In recent years, teleoperation has shown great potentials in different fields such as spatial, mining, under-water, etc. When teleoperation is required to be bilateral, the time delay induced by a potentially large physical distance prevents a good performance of the controller, especially in case of contact. When bilateral teleoperation is introduced to the field of medicine, a new challenge arises: the controller needs to be used in both hard and soft environments. For example, in the context of telesurgery, the robot can enter in contact with both bone (hard) and organ (soft). In an attempt to enrich existing controller designs to better suit the medical needs, an adaptive fuzzy logic controller is designed in this text. It simulates human intelligence and adapts the controller to environments of different stiffness coefficients. It is compared to three other classical controllers used in the field of bilateral teleopeartion and demonstrates very interesting potential.

Iconography of the Virgin Mary

description: This is a study of the physical manifestation of the cult of the Virgin Mary in Late Antique Egypt, that is, of the point at which Marian veneration, which scholars generally agree coalesced in the fifth century, spilled over into the physical sphere. Three diverging source materials (papyri/inscriptions, archaeology and iconography) are explored in order to answer the central question, which asks: to what extent does the evidence for the physical materialization of the cult of Mary reflect its geographical and chronological diffusion in Late Antique Egypt? Each of the sources materials are collected and analyzed in an independent chapter. The study begins with the papyrological/epigraphical evidence, as it represents the largest body of materials and offers the most substantial datable evidence. Although the papyri and inscriptions are not themselves tangible manifestations of the cult of Mary, they nevertheless mention at least 23 churches or monasteries that were dedicated to her. In Chapter 2, the extant archaeological evidence supplements the data collected in the textual materials by providing an analysis of the layout and iconographical programmes of the few churches of Mary that are actually preserved. Chapter 3 collects 43 wall paintings that depict Mary and analyzes their varying iconographic patterns and immediate spatial contexts. The individual source materials are then brought together for a broader geographical and chronological investigation, which demonstrates that despite the assumed presence of a cult of Mary by the fifth century, this was only the starting point for the consolidation and diffusion of her cult, which reached its peak in the sixth and, especially, the seventh century. This study is the first synthesis of the physical output of the cult of Mary in Late Antique Egypt and thus advances our knowledge of her integration into the society of Christian Egypt on both the chronological and topographical axes. As such, it is also of importance to studies of her cult elsewhere in the Late Antique world, where sources may not be as plentiful and varied.
It takes real balls to have a heart in politics

description: Political insults too often rely on inaccurate bodily references. With the revelations (strictly in the public interest) of Kevin Rudd's heart surgery, the language of the heart has re-entered Australian politics, admittedly through the back door. The media is awash with tickers, motors and other desperately lame metaphorical constructions involving matters of the heart. In letters to newspapers, readers remind the Prime Minister that a surgically tinkered-with heart is not such a bad thing after all. Better a patched-up broken heart than no heart at all, eh John? The PM, of course, has his own view of what hearts are for, especially if they happen to be beating in politicians' chests. His repeated questioning of Kim Beazley's ticker a few years ago and the focus on Rudd's surgery makes it clear that in John Howard's eyes hearts are measured in litres, like engines. And it goes without saying, that Australia's present and future leaders, the ones truly fit for the job, need to have the top-performing all-terrain models, the kinds that last.

description: Cette recherche se veut une analyse de l’évolution des discours juridique et médical dans l’interprétation du « crime » de tentative de suicide. Afin de donner un sens à la déconstruction juridique de ce crime, nous avons étudié les procès pour tentative de suicide au Québec de 1892, année du premier Code criminel canadien, à 1972, année de la décriminalisation. Les conclusions illustrent qu’au XXe siècle, le discours médical a pris une place toujours plus importante dans les tribunaux québécois en matière de tentative de suicide, alors que la psychiatrie se développe dans la province. On assiste alors à un glissement dans la forme du contrôle social des individus qui commettent des tentatives de suicide, c’est-à-dire que le contrôle social pénal est progressivement remplacé par un contrôle social thérapeutique. Le point culminant de cette transformation est la décriminalisation de la tentative de suicide en 1972.

description: The following thesis applies equations of motion used in linear locomotion (gait analysis) to the analysis of the purely rotational motion of the fouetté or tour à la seconde. Modifications to the method of analysis include the creation of several MATLAB programs to compute improved estimates of the moment of inertia tensor, three-dimensional angular momentum about the dancer’s centre of mass. The results of this investigation—the quantification of angular momentum and external moments—are compared to similar results from gait analysis to demonstrate how the dancer maintains balance during rotational motion. The variables calculated by the MATLAB programs are particularly relevant in the field of balance control research in the context of inputs into the body’s balance control systems.

description: This thesis will focus on spherical near-field antenna measurements and the methods developed or modified for the work of this thesis to estimate the uncertainty in a particular far-field radiation pattern. We will discuss the need for error assessment in spherical near-field antenna measurements. A procedure will be proposed that, in an automated fashion, can be used to determine the overall uncertainty in the measured far-field radiation pattern of a particular antenna. This overall uncertainty will be the result of a combination of several known sources of error common to SNF measurements. This procedure will consist of several standard SNF measurements, some newly developed tests, and several stages of post-processing of the measured data. The automated procedure will be tested on four antennas of various operating frequencies and directivities to verify its functionality. Finally, total uncertainty data will be presented to the reader in several formats.

The Requirement of Toll-like Receptor Signaling in the Induction of Humoral and Cell-mediated Immune Responses to the Orally Administered Dukoral® Vaccine

description: Only a limited number of orally-administered vaccines have been licensed, such as the Dukoral vaccine, comprised of killed whole-cell Vibrio cholerae and cholera toxin B subunit (CTB). Thus far, mechanistic details underlying the resulting protective immune generated by this vaccine, including the requirement of Toll-like receptor (TLR) signaling, remain largely unknown. Herein, I investigated the involvement of TLR signaling in the induction of humoral immune responses following oral and intramuscular immunization with Dukoral or its components by using TLR-2-, TLR-4-, MyD88- and Trif-deficient mice. I showed that wild type and all groups of TLR-deficient mice generated similar levels of V. cholerae- and CTB-specific IgG1 and IgG2c serum antibodies, and fecal IgA antibodies, following oral immunization with Dukoral, and with CTB alone. Additionally, the agglutinating activity of V. cholerae-specific antibodies was also found to occur independently of MyD88 signaling. However, intramuscular immunization with Dukoral, as well as with CTB alone, required MyD88 signaling for the induction of CTB-specific IgG1and IgG2c serum antibodies. I also evaluated the involvement of TLR signaling in the induction of splenic cell-mediated immune responses following oral immunization with Dukoral. My results showed that CD4+ T-cell and CD19+ B cell proliferation occurred in a MyD88-dependent manner in response to stimulation by V. cholerae or CTB. In contrast, in response to CTB stimulation, Trif negatively regulated both CD4+ T-cell and CD19+ B-cell proliferation. Splenocytes from MyD88-/-, Trif-/-, TLR-2-/-, and TLR-4-/- mice were significantly inhibited in their ability to secrete IFN-γ in response to stimulation by V. cholerae. Furthermore, maturation of dendritic cells (DCs), as measured by increased cell-surface CD80, CD86, CD40, and MHCII expression and cytokine secretion was shown to occur in a MyD88-dependent manner in response to stimulation with Dukoral vaccine components. However, despite the impaired ability of MyD88-/- DCs to mature, MyD88-/- animals, and indeed all TLR-deficient animals tested, showed serum and fecal antibody responses comparable to those seen in wild-type animals. Taken together, my results suggest that humoral responses (antibody production and agglutinating ability), following oral immunization with Dukoral, were able to occur independently of TLR signaling and DC maturation. This TLR-independence in the generation of humoral responses was lost when the vaccine was administered parenterally. Cell-mediated immune responses (cell proliferation, DC maturation, and cytokine secretion) were found to be TLR-dependent.
