Overrun & undermined : the alteration of park atmospheres in the Canadian Rockies
Creators: name: Sziklasi, Connor
Publisher: name: University of British Columbia
Year: 2025

description: This thesis examines how the affective atmospheres of park spaces in Yoho and Banff national parks have become incongruous with the desired visitor experience as a result of being increasingly mediated by capital. Yoho and Banff, located in the Rocky Mountains of British Columbia and Alberta respectively, are Canada’s most longstanding protected areas in addition to being among its most well-known and well-attended. Increasing attendance is one of several changes—along with infrastructure developments, use of social media and smartphones, and park management decisions¬—that have, in recent years, sparked concern among visitors, locals, and park staff of a perceived imbalance in the dual mandate of simultaneously protecting and promoting parks across the country and beyond. I engage with non-Indigenous recreationists, tourists, and locals of Yoho and Banff on a variety of parks-related topics, including the current state of protected areas and their affective atmospheres, including what changes many are hoping to see within them. I employ ethnographic research methods such as semi-structured interviews, informal interactions, nonhuman observation, and “walk-and-talks” on park trails to help learn of the relationships that non-Indigenous people hold with these spaces as well as the values at the core of these relationships. Through the analysis of these interactions and observations, I identify the inherent contradiction embedded within “the world’s craziest mandate” and demonstrate how it is neither protection nor promotion but the balancing of the two that defines the values and desired atmospheres of parks organizations and their patrons. I then explore the ways in which atmospheres have become compromised by processes of fetishization and an increasingly image-centred set of behaviours among growing crowds. I attribute recent atmospheric changes as the result of Parks Canada’s centralization and resultant delocalization of power and point to the integral role of local, intimate knowledges in the management of park spaces.

Tourism and community sustainability: The case of Senneterre, Quebec.
Creators: name: Georgescu, Denisa Cristina.
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 1998
Subjects: subject: Geography.

description: This thesis analyzes the potential of recreation and tourism development in Senneterre and examines if it can compensate for the downturn of its traditional forest-based economy and contribute to its long-term sustainability. More specifically, the research focuses on the current supply of and demand for the main recreation and tourism assets (attractions, services and infrastructure, promotion, and hospitality) within the community. Attention is given to the strengths and weaknesses of both supply and demand. The community leaders' perceptions and support of recreation and tourism development as sustainable initiatives for Senneterre are also investigated. The research methodology combines archival research of governmental and non-governmental documents related to recreation and tourism in the Abitibi-Temiscamingue region and survey research involving key representatives of the community. The survey includes informal, exploratory interviews with purposefully selected community members and mailed questionnaires to knowledgeable representatives of various groups such as business people and politicians, recreation and tourism providers, as well as representatives of the First Nations. In this research, a literature review also serves as an important source of information regarding major issues concerning forest dependent communities, sustainable rural tourism, and community development.

description: Background: Street-involved youth who use illicit drugs are at high risk for health-related harms; however, the profile of youth at greatest risk of hospitalization has not been well described. We sought to characterize hospitalization among street-involved youth who use illicit drugs and identify the most frequent medical reasons for hospitalization among this population. Methods: From January 2005 to May 2016, data were collected from the At-Risk Youth Study (ARYS), a prospective cohort study of street-involved youth in Vancouver, Canada. Multivariable generalized estimating equation (GEE) was used to identify factors associated with hospitalization. Results: Among 1216 participants, 373 (30.7%) individuals reported hospitalization in the previous 6 months at some point during the study period. The top three reported medical reasons for hospital admission were the following: mental illness (37.77%), physical trauma (12.77%), and drug-related issues (12.59%). Factors significantly associated with hospitalization were the following: past diagnosis of a mental illness (adjusted odds ratio [AOR] = 1.85; 95% confidence interval [95% CI] 1.47–2.33), frequent cocaine use (AOR = 2.15; 95% CI 1.37–3.37), non-fatal overdose (AOR = 1.76; 95% CI 1.37–2.25), and homelessness (AOR = 1.40; 95% CI 1.16–1.68) (all p < 0.05). Conclusions: Findings suggest that mental illness is a key driver of hospitalization among our sample. Comprehensive approaches to mental health and substance use in addition to stable housing offer promising opportunities to decrease hospitalization among this vulnerable population.

description: Background: Radiotherapy for localised prostate cancer has many known and distressing side effects. The efficacy of group interventions for reducing psychological morbidity is lacking. This study investigated the relative benefits of a group nurse-led intervention on psychological morbidity, unmet needs, treatment-related concerns and prostate cancer-specific quality of life in men receiving curative intent radiotherapy for prostate cancer. Methods: This phase III, two-arm cluster randomised controlled trial included 331 men (consent rate: 72 %; attrition: 5 %) randomised to the intervention (n = 166) or usual care (n = 165). The intervention comprised four group and one individual consultation all delivered by specialist uro-oncology nurses. Primary outcomes were anxious and depressive symptoms as assessed by the Hospital Anxiety and Depression Scale. Unmet needs were assessed with the Supportive Care Needs Survey-SF34 Revised, treatment-related concerns with the Cancer Treatment Scale and quality of life with the Expanded Prostate Cancer Index -26. Assessments occurred before, at the end of and 6 months post-radiotherapy. Primary outcome analysis was by intention-to-treat and performed by fitting a linear mixed model to each outcome separately using all observed data. Results: Mixed models analysis indicated that group consultations had a significant beneficial effect on one of two primary endpoints, depressive symptoms (p = 0.009), and one of twelve secondary endpoints, procedural concerns related to cancer treatment (p = 0.049). Group consultations did not have a significant beneficial effect on generalised anxiety, unmet needs and prostate cancer-specific quality of life. Conclusions: Compared with individual consultations offered as part of usual care, the intervention provides a means of delivering patient education and is associated with modest reductions in depressive symptoms and procedural concerns. Future work should seek to confirm the clinical feasibility and cost-effectiveness of group interventions.

Partial Differential Equations

description: This thesis consists of 4 parts on the analysis of singularities that arise from conformal geometry, geometric flows, and geometric inequalities.
description: In the first part, we study the constant Q-curvature metrics on conic 4 manifolds. We introduce 3 different types of configurations of conic singularities: stable, semi-stable, and unstable. In the stable case, we prove the existence of a constant Q-curvature metric in the conformal class. For conic 4-sphere with at most 2 singularities, we classify the solutions. They are rotational symmetric metrics on conic 4-sphere with identical cone type at each singularity and they correspond to the semi-stable configuration. Along the study, we derive an asymptotic expansion of the constant Q-curvature metric near conic singularities which is of independent interest.
description: In the second part, we study the curve-shortening-flow (CSF) on Riemann surfaces with possible ambient conic singularities. We generalize a comparison function due to Huisken which was originally defined for CSF on plane to surfaces. We obtain a new proof of the classic Gage-Hamilton-Grayson theorem on surfaces by studying the first time singularities of the flow. If the ambient Riemann surface admits conic singularities, we prove that under the flow, embedded simple closed curves cannot touch conic singularities with cone angles less than or equal to π.
description: In the third part, we generalize the Andrews’ inequality to manifolds with conic singularities and with boundary. We establish the rigidity result when the equality holds.
description: In the last part of the thesis, we prove a Liouville type theorem for an one parameter family of 2-Hessian type fully non-linear elliptic equations on R^4 . When the parameter ρ runs from 1 to 0, the equations interpolate between the σ2 -Yamabe equation and the 2-Hessian equation. Our theorem holds for ρ > 0. Our approach contains 2 important ingredients: one is a monotonic quasi-local mass type quantity defined on the level sets of the solution; another is a series of estimates which controls the asymptotic shape of level sets of u at infinity.
Subject-predicate agreement restrictions in Persian
Creators: name: Sedighi, Anousha
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 2005
Subjects: subject: Language, Linguistics.

description: This work investigates two distinct constructions which appear to induce a constraint on verbal agreement. The first construction involves inanimate plural subjects and verbs appearing in third person singular/default morphology. Adopting the framework of Distributed Morphology which has recently been used as a key to capturing several agreement restrictions in languages, I propose that the restriction caused by Animacy in Persian resides in post-syntactic morphology through an impoverishment operation. The second construction I study contains Psychological predicates which have not been entirely explored from the point of view of Psychological Constructions in the previous literature. The nominative experiencer does not induce agreement on the verb and the verb appears in third person singular, which provides evidence for separation of agreement and Nominative case assignment. I argue that the lack of verbal agreement in Persian Psychological constructions is only apparent and I provide evidence to show that they do not involve compound verbs. I propose that these constructions have a Tense requirement and involve applied arguments. The experiencer is licensed by a Super High Applicative head which takes a TP (a sentential predication/full proposition) as complement. Furthermore, I propose that the Super High Applicative phrase is a strong phase, a new category to be added to the set of strong phases proposed by Chomsky 1999-2004.

description: Video Shadow Detection (VSD) aims to detect the shadow masks with frame sequence. Existing works suffer from inefficient temporal learning. Moreover, few works address the VSD problem by considering the characteristic (i.e., boundary) of shadow. Motivated by this, we propose a Timeline and Boundary Guided Diffusion (TBGDiff) network for VSD where we take account of the past-future temporal guidance and boundary information jointly. In detail, we design a Dual Scale Aggregation (DSA) module for better temporal understanding by rethinking the affinity of the long-term and short-term frames for the clipped video. Next, we introduce Shadow Boundary Aware Attention (SBAA) to utilize the edge contexts for capturing the characteristics of shadows. Moreover, we are the first to introduce the Diffusion model for VSD in which we explore a Space-Time Encoded Embedding (STEE) to inject the temporal guidance for Diffusion to conduct shadow detection. Benefiting from these designs, our model can not only capture the temporal information but also the shadow property. Extensive experiments show that the performance of our approach overtakes the state-of-the-art methods, verifying the effectiveness of our components. We release the codes, weights, and results at \url{https://github.com/haipengzhou856/TBGDiff}.

description: The complexity of the clinical management of neuroendocrine neoplasia (NEN) is exacerbated by limitations in imaging modalities and a paucity of clinically useful biomarkers. Limitations in currently available imaging modalities reflect difficulties in measuring an intrinsically indolent disease, resolution inadequacies and inter-/intra-facility device variability and that RECIST (Response Evaluation Criteria in Solid Tumors) criteria are not optimal for NEN. Limitations of currently used biomarkers are that they are secretory biomarkers (chromogranin A, serotonin, neuron-specific enolase and pancreastatin); monoanalyte measurements; and lack sensitivity, specificity and predictive capacity. None of them meet the NIH metrics for clinical usage. A multinational, multidisciplinary Delphi consensus meeting of NEN experts (n = 33) assessed current imaging strategies and biomarkers in NEN management. Consensus (>75%) was achieved for 78% of the 142 questions. The panel concluded that morphological imaging has a diagnostic value. However, both imaging and current single-analyte biomarkers exhibit substantial limitations in measuring the disease status and predicting the therapeutic efficacy. RECIST remains suboptimal as a metric. A critical unmet need is the development of a clinico-biological tool to provide enhanced information regarding precise disease status and treatment response. The group considered that circulating RNA was better than current general NEN biomarkers and preliminary clinical data were considered promising. It was resolved that circulating multianalyte mRNA (NETest) had clinical utility in both diagnosis and monitoring disease status and therapeutic efficacy. Overall, it was concluded that a combination of tumor spatial and functional imaging with circulating transcripts (mRNA) would represent the future strategy for real- time monitoring of disease progress and therapeutic efficacy.

description: The suitability of wild boar liver as a bioindicator of per- and polyfluoroalkyl substances (PFAS) in the terrestrial environment was investigated. Samples from 50 animals in three different areas associated with (1) contaminated paper sludges distributed on arable land (PS), (2) industrial emissions of PFAS (IE) and (3) background contamination (BC) were analyzed for 66 PFAS, including legacy PFAS, novel substitutes and precursors of perfluoroalkyl acids (PFAAs). Additionally, the Total Oxidizable Precursor (TOP) assay was performed to determine the formation potential of PFAAs from precursors. In total, 31 PFAS were detected with site-specific contamination profiles. PFAS concentrations in livers from area PS and IE (567 and 944 (micro)g kg-1 wet weight, respectively) were multiple times higher than from area BC (120 (micro)g kg-1). The dominating PFAS were the legacy compounds perfluorooctane sulfonic acid (PFOS) in areas PS and BC (426 and 82 (micro)g kg-1, respectively) and perfluorooctanoic acid (PFOA) in area IE (650 (micro)g kg-1). In area IE, the compounds 4,8-dioxa-3H-perfluorononanoic acid (DONA) and hexafluoropropylene oxide dimer acid (HFPO-DA) - which are used as substitutes for PFOA - were determined at 15 and 0.29 (micro)g kg-1, respectively. The formation potential of PFAAs was highest in area PS, but generally lower than the contamination with PFAAs. The pattern of perfluoroalkyl carboxylic acids (PFCAs) in wild boar liver reflects the contamination of the local soil at the two hot-spot areas IE and PS. This first comparison of PFAS contamination between wild boars and soil suggests that wild boar livers are suitable bioindicators for PFAS contamination in the terrestrial environment. Moreover, in terrestrial samples from area IE, legacy PFAS were found to be retained for a longer period as compared to riverine samples (suspended particulate matter and chub filet). © 2023 The Authors

description: The most prodigious starburst galaxies are absent in massive galaxy clusters today, but their connection with largescale environments is less clear at z ≳ 2. We present a search of large-scale structure around a galaxy cluster core at z = 2.095 using a set of spectroscopically confirmed galaxies. We find that both color-selected star-forming galaxies (SFGs) and dusty star-forming galaxies (DSFGs) show significant overdensities around the z = 2.095 cluster. A total of eight DSFGs (including three X-ray luminous active galactic nuclei, AGNs) and 34 SFGs are found within a 10 radius (corresponds to ∼15 cMpc at z ∼ 2.1) from the cluster center and within a redshift range of Δz = 0.02, which leads to galaxy overdensities of δDSFG ∼ 12.3 and δSFG ∼ 2.8. The cluster core and the extended DSFG- and SFG-rich structures together demonstrate an active cluster formation phase, in which the cluster is accreting a significant amount of material from large-scale structure while the more mature core may begin to virialize. Our finding of this DSFG-rich structure, along with a number of other protoclusters with excess DSFGs and AGNs found to date, suggest that the overdensities of these rare sources indeed trace significant mass overdensities. However, it remains puzzling how these intense star formers are triggered concurrently. Although an increased probability of galaxy interactions and/or enhanced gas supply can trigger the excess of DSFGs, our stacking analysis based on 850 μm images and morphological analysis based on rest-frame optical imaging do not show such enhancements of merger fraction and gas content in this structure.

description: In 1955, Henry Dye showed that factors with isomorphic unitary groups are in a certain sense isomorphic, provided they are not of type $I\sb{2n}.$ We establish a similar result for simple AF algebras, namely that the unitary group of a simple AF algebra is a complete invariant. Also, there appears to be an error in Dye's paper which allows us to strengthen his result so that it is valid for factors not of type $I\sb2.$

description: Over the past decade, teaching and learning in virtual worlds has been at the forefront of many higher education institutions around the world. The DEHub Virtual Worlds Working Group (VWWG) consisting of Australian and New Zealand higher education academics was formed in 2009. These educators are investigating the role that virtual worlds play in the future of education and actively changing the direction of their own teaching practice and curricula. 47 academics reporting on 28 Australian higher education institutions present an overview of how they have changed directions through the effective use of virtual worlds for diverse teaching and learning activities such as business scenarios and virtual excursions, role-play simulations, experimentation and language development. The case studies offer insights into the ways in which institutions are continuing to change directions in their teaching to meet changing demands for innovative teaching, learning and research in virtual worlds. This paper highlights the ways in which the authors are using virtual worlds to create opportunities for rich, immersive and authentic activities that would be difficult or not possible to achieve through more traditional approaches.

description: Recently, the Entropy Ensemble Filter (EEF) method was proposed to mitigate the computational cost of the Bootstrap AGGregatING (bagging) method. This method uses the most informative training data sets in the model ensemble rather than all ensemble members created by the conventional bagging. In this study, we evaluate, for the first time, the application of the EEF method in Neural Network (NN) modeling of El Nino-southern oscillation. Specifically, we forecast the first five principal components (PCs) of sea surface temperature monthly anomaly fields over tropical Pacific, at different lead times (from 3 to 15 months, with a three-month increment) for the period 1979–2017. We apply the EEF method in a multiple-linear regression (MLR) model and two NN models, one using Bayesian regularization and one Levenberg-Marquardt algorithm for training, and evaluate their performance and computational efficiency relative to the same models with conventional bagging. All models perform equally well at the lead time of 3 and 6 months, while at higher lead times, the MLR model’s skill deteriorates faster than the nonlinear models. The neural network models with both bagging methods produce equally successful forecasts with the same computational efficiency. It remains to be shown whether this finding is sensitive to the dataset size.
Building the National Broadband Network

description: The current Australian Government policy calls for every house, school and business in Australia to get access to 'affordable fast broadband' over an eight-year period in a National Broadband Network. There has been much discussion about the viability of this policy and the associated NBN Co, but much less about the technical implementation of this policy. The article looks at the techniques likely to be used to provide fast broadband to individual dwellings, techniques which will have to provide access to over 4000 dwellings each day to realise the Australian Government's policy.
Viscoelastic flows around spheres.

Subjects: subject: Engineering, Chemical.

description: The present thesis is concerned with the flow of viscoelastic liquids in channels and around spheres contained in cylinders. Problems that have been tackled are the Poiseuille flow between parallel plates and in tubes, where all models give excellent results checked against analytical solutions for a range of elasticity levels determined by a dimensionless Weissenberg number (Ws). The drag coefficient on the sphere shows a monotonic decrease with increasing Ws, from 5.9522 for Ws = 0 to 5.4935 for Ws = 0.3. Non-zero second normal stress differences decrease the drag even further. The unbounded flow around spheres was simulated using a 50:1 diameter ratio. Findings suggest that slip on the sphere surface may be occurring at moderate to high Ws numbers, which has the effect of lowering the drag calculated on the sphere. (Abstract shortened by UMI.)

description: Background Antimicrobial resistance is an increasing challenge in low and middle-income countries as it is widespread in these countries and is linked to an increased mortality. Apart from human and environmental factors, animal-related drivers of antimicrobial resistance in low- and middle-income countries have special features that differ from high-income countries. The aim of this narrative review is to address the zoonotic sources and the spread of antimicrobial resistance from the perspective of low- and middle-income countries. Main body Contamination with extended-spectrum beta-lactamase (ESBL)-producing Escherichia coli is highest in poultry (Africa: 8.9-60%, Asia: 53-93%) and there is a risk to import ESBL-producing E. coli through poultry meat in Africa. In aquacultures, the proportion of ESBL-producers among E. coli can be high (27%) but the overall low quality of published studies limit the general conclusion on the impact of aquacultures on human health. ESBL-producing E. coli colonization of wildlife is 1-9% in bats or 2.5-63% birds. Since most of them are migratory animals, they can disperse antimicrobial resistant bacteria over large distances. So-called 'filth flies' are a relevant vector not only of enteric pathogens but also of antimicrobial resistant bacteria in settings where sanitary systems are poor. In Africa, up to 72.5% of 'filth flies' are colonized with ESBL-producing E. coli, mostly conferred by CTX-M (24.4-100%). While methicillin-resistant Staphylococcus aureus plays a minor role in livestock in Africa, it is frequently found in South America in poultry (27%) or pork (37.5-56.5%) but less common in Asia (poultry: 3%, pork: 1-16%). Conclusions Interventions to contain the spread of AMR should be tailored to the needs of low- and middle-income countries. These comprise capacity building of diagnostic facilities, surveillance, infection prevention and control in small-scale farming. © The Author(s) 2023.
The persistence, transport and metabolism of fenitrothion in conifers.

description: An investigation was carried out to determine the fate and persistence of fenitrothion (0,0-dimethyl-0-(3-methyl-4-nitrophenyl)-phosphorothioate), applied to four year old seedlings of balsam fir, white spruce, and Jack pine under greenhouse conditions. The insecticide disappeared rapidly from the surface of conifer tissue while the absorbed residues were more persistent. Greater absorption of the pesticide was coupled with increasing persistence in pine, spruce and fir. An in vitro study carried out on glass surfaces demonstrated that rapid disappearance of the pesticide was primarily due to volatilization. TLC analysis of the conifer extracts was consistent with this dissipation mechanism since 14C-ring degradation products were present for the most part only in trace amounts. Autoradiographic tracing studies demonstrated the ability of 14C-fenitrothion to be transported acropetally into the young foliage of fir, and to a lesser extent in spruce. That this took place via the xylem (apoplastic transport) was confirmed by histoautoradiography. These results were taken as evidence for the systemic potential of fenitrothion for budworm control.

description: This thesis investigates the potential of enzymatic hydrolysis to reduce energy consumption in refining mechanical pulps, specifically bleached chemi-thermomechanical pulp. Mechanical pulping, although advantageous for high yield and sustainability, remains energy-intensive, with significant energy consumption during fibre separation and development. This research explores how enzymatic treatments, particularly cellulases, can enhance refining efficiency by modifying fibre structures, thus reducing the energy required for refining without compromising fibre quality. This study evaluates the effects of enzyme incubation conditions – such as pH, temperature, duration, and enzyme dosage – on fibre morphology and refining energy through a series of laboratory and pilot-scale experiments. Results show that enzymatic hydrolysis can facilitate fibre shortening and fines generation during refining compared to unhydrolyzed BCTMP. These findings suggest that enzymatic treatments increase fibres’ susceptibility to mechanical action by weakening their structure, promoting greater fibrillation, and improving water drainage. Softwood BCTMP exhibited significant energy savings, while hardwood BCTMP, particularly aspen, showed more limited effects, with enzymatic hydrolysis modifying the fibres’ response to repulping. Thus, enzyme treatments should be tailored for different wood species. Moreover, the study indicates that alkaline incubation conditions improve enzyme diffusion and fibre modification, potentially reducing the need for buffer solutions in industrial-scale applications. However, the research also highlights challenges, such as the need for further investigation into enzyme combinations and the impacts of different wood species and pulping processes on enzyme efficiency. The findings contribute to a better understanding of enzymatic hydrolysis as an energy-efficient strategy in pulp refining, presenting a sustainable approach to improving pulp and paper production efficiency. Enzymatic hydrolysis presents a promising approach for reducing energy consumption in mechanical pulping. By modifying fibre structure to enhance refining efficiency, enzymatic treatments can contribute to sustainability in the pulp and paper industry. Future research should investigate multi-enzyme systems and broaden the application to other pulping processes and wood species to further optimize and scale this technology.
Long-term deflections analysis of reinforced concrete flat plates under construction loads.

description: Relatively large construction loads applied to immature slabs with their low elastic moduli will cause large initial elastic deflections. The high applied stress/developed strength ratio will cause significant creep, resulting in large long-term deflections. Shrinkage, while not related to construction loads, also contributes to long-term deflections. Studies reported by many investigators showed that the long-term deflections cannot be ignored in the design process and that the contribution of the effects of the construction loads cannot be ignored. The influence of the construction loads on the long-term deflection serviceability means that the construction process cannot be independent of the design considerations. However, ACI 318 and CSA A23.3, specify maximum span thickness ratios for which deflections need not be considered. A computer investigation of the long-term deflections for flat plates, of typical dimensions, was effected using a finite element analysis program for several possible load histories. The study indicated that the present span thickness recommendations of ACI 318 and CSA A23.3 would not necessarily prevent excessive deflections. The study also indicates that, in most cases, the code requirement of total deflection not to exceed l/240 was critical and could not be met.

description: In the present investigation we have performed intracellular recordings from mesencephalic trigeminal nucleus (MeV) neurons in an in vitro brain slice preparation to reevaluate the effects of two likely candidate neurotransmitters, glutamate and serotonin, on MeV neurons. Recorded neurons were observed to depolarize in response to exogenously applied glutamate, N-methyl-D-aspartic acid (NMDA), kainate (KA), and (R,S)-$\alpha$-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA). The agonists generally evoked larger responses than glutamate, and exhibited a long duration desensitization requiring approximately ten minutes for full recovery. Some cross-desensitization between the glutamate agonists was also observed. MeV neurons exhibit voltage-dependent subthreshold high-frequency oscillatory activity that may be activated during excitatory amino acid (EAA)-induced depolarizations to enhance their excitability. Exogenously applied serotonin was observed to cause small depolarization of MeV neurons accompanied by substantial reductions in input resistance. The response was determined to result from activation of the inward rectifier, I$\rm\sb{h}.$ Applications of forskolin, 8-bromo-cAMP, and IBMX, substances known to elevate intracellular adenosine $3\sp\prime,5\sp\prime$-cyclic monophosphate (cAMP), were observed to mimic the serotonin response suggesting that the second messenger system mediating the serotonin response involves activation of adenylyl cyclase leading to an increase in intracellular cAMP. The serotonin response could be reproduced with the serotonin agonist, 5-carboxamidotryptamine (5-CT), but not by 8-hydroxy-2-(di-N-propylamino)-tetralin (8-OH-DPAT), and could be antagonized by ketanserin but not by methiothepin. It is speculated that serotonin input contributes to the excitability level of MeV neurons by regulating the degree of activation of I$\rm\sb{h}.$ (Abstract shortened by UMI.)

description: During the past few years, various healthcare models and e-Health 2.0 technologies have been developed in order to effectively deliver the right information to the right process to provide effective and efficient healthcare services. On the other hand, healthcare delivery is evolving from disease-centered to patient-centered where patients are active participants in their healthcare delivery. Thus communications and collaboration among different healthcare actors is taking place on a much larger scale. There is also an increasing demand for personalized health systems facilitating the effective management of information, simplifying communication and collaboration, and supporting applications and services for meeting different users' specific requirements and ongoing needs. In order to properly address the aforementioned challenges, a framework is needed to advance information integration and interoperability of health applications and services in a controlled manner. In this thesis, we present a framework which allows patients and other healthcare actors to collaboratively develop personalized online health applications according to their specific and ongoing needs and requirements. For this purpose, we illustrate how Web 2.0 collaborative technologies, such as mashups, can represent an adequate foundation for implementing such framework. The value and capabilities of mashups in healthcare have already been studied and demonstrated, and this technology is able to provide an interoperable framework for communication and integration between healthcare processes and applications. We believe that integration and interoperability of health applications/services can be defined at the following levels: Process Level, System Level, and Data Level. The interoperability and integration of services at the system and data levels have already been intensively researched. However, not enough consideration has been given to interoperability issues at the process level. Healthcare must have interoperable systems and interoperable people who will use the systems. Therefore, a shift from a technology-driven implementation to a process-driven conceptual model is needed. Our aim in this thesis is to further research how Web 2.0 technologies and tools, such a mashups, can facilitate the exchange of processes between various healthcare entities and actors, and the role of mashup patterns for enhancing the interoperability and integration of healthcare services and applications.
Broadband: what is the problem to be solved, and is NBN solving it?

description: A striking feature of the Rudd-Gillard Government's NBN policy - to spend over $50 billion of taxpayers' money on a 100 Mbps fibre to the premises network serving over 10 million premises - is the lack of clarity about the problem this policy is designed to solve. In this article I argue that the NBN was announced for political reasons rather than policy reasons. After briefly explaining that point, the paper then discusses the policy issues - by identifying and assessing several 'candidate problems' that NBN might be thought to be designed to address, and argues that the policy as is presently being pursued is not a good solution to any of these. The paper concludes with some suggestions for a more sensible approach.
