Measurement and statistical analysis of the passive viscoelastic properties of the human knee joint during flexion and extension motion.
Creators: name: McFaull, Steven R.
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 1993
Subjects: subject: Applied Mechanics.

description: The purpose of the present investigation was to determine the net passive elastic joint moment and the angular damping coefficient of the human knee joint in full range flexion-extension. A secondary purpose was to develop regression equations to predict the measured passive properties from anthropometric data. The passive elastic moments increased exponentially as the limits of either flexion or extension were approached. The midrange of joint motion was a low moment (5 N$\cdot$m), low stiffness region. Considerable variability in the magnitudes of the passive elastic moments existed across subjects. At 140$\sp\circ$ of flexion, between about 5 N$\cdot$m and 86 N$\cdot$m was measured while the range at full extension (0$\sp\circ$) was about 6 N$\cdot$m to 22 N$\cdot$m. The angular damping coefficient was a nonlinear function (approximately quadratic) of the knee joint angle. The variability was not quite as high compared to the elastic component. Application of the data to the late swing phase of walking indicated that, for some subjects, the passive moments may contribute (or oppose) significantly to the net joint moment.

Subjects: subject: Engineering, Electronics and Electrical.

description: This thesis addresses the performance analysis and improvement of Wireless IEEE 1394 networks. Wireless IEEE 1394 appears to be the only existing QoS capable broadband wireless home networking solution that has been standardized. Our study investigates the performance of the original Wireless 1394 protocol. It also addresses protocol extensions that improve the original Wireless 1394 network, as well as add new useful functionalities. The performance analysis has taken into consideration the behaviour of the wireless channel through simple, yet effective and widely used model. The evaluation demonstrated the strong potential of Wireless IEEE 1394. They also uncovered some weaknesses, which our protocol extensions addressed successfully.
Spatio-temporal feedback in stochastic neural networks

Subjects: subject: Physics, General.

description: The mechanisms by which groups of neurons interact is an important facet to understanding how the brain functions. Here we study stochastic neural networks with delayed feedback. The first part of our study looks at how feedback and noise affect the mean firing rate of the network. Secondly we look at how the spatial profile of the feedback affects the behavior of the network. Our numerical and theoretical results show that negative (inhibitory) feedback linearizes the frequency vs input current (f-I) curve via the divisive gain effect it has on the network. The interaction of the inhibitory feedback and the input bias is what produces the divisive decrease in the slope (known as the gain) of the f-I curve. Our work predicts that an increase in noise is required along with increase in inhibitory feedback to attain a divisive and subtractive shift of the gain as seen in experiments [1]. Our results also show that, although the spatial profile of the feedback does not effect the mean activity of the network, it does influence the overall dynamics of the network. Local feedback generates a network oscillation, which is more robust against disruption by noise or uncorrelated input or network heterogeneity, than that for the global feedback (all-to-all coupling) case. For example uncorrelated input completely disrupts the network oscillation generated by global feedback, but only diminishes the network oscillation due to local feedback. This is characterized by 1st and 2nd order spike train statistics. Further, our theory agrees well with numerical simulations of network dynamics.

description: Background: The aquatic flowering-plant family Hydatellaceae has a classic Gondwanan distribution, as it is found in Australia, India and New Zealand. To shed light on the biogeographic history of this apparently ancient branch of angiosperm phylogeny, we dated the family in the context of other seed-plant divergences, and evaluated its biogeography using parsimony and likelihood methods. We also explicitly tested the effect of different extinction rates on biogeographic inferences. Results We infer that the stem lineage of Hydatellaceae originated in the Lower Cretaceous; in contrast, its crown originated much more recently, in the early Miocene, with the bulk of its diversification after the onset of the Pliocene. Biogeographic reconstructions predict a mix of dispersal and vicariance events, but considerations of geological history preclude most vicariance events, besides a split at the root of the family between southern and northern clades. High extinction rates are plausible in the family, and when these are taken into account there is greater uncertainty in biogeographic inferences. Conclusions A stem origin for Hydatellaceae in the Lower Cretaceous is consistent with the initial appearance of fossils attributed to its sister clade, the water lilies. In contrast, the crown clade is young, indicating that vicariant explanations for species outside Australia are improbable. Although long-distance dispersal is likely the primary driver of biogeographic distribution in Hydatellaceae, we infer that the recent drying out of central Australia divided the family into tropical vs. subtropical/temperate clades around the beginning of the Miocene.
Arabic in Iraq, Syria, and southern Turkey
Creators: name: Procházka, Stephan
Publisher: name: Zenodo
Year: 2020

description: This chapter covers the Arabic dialects spoken in the region stretching from the Turkish province of Mersin in the west to Iraq in the east, including Lebanon and Syria. The area is characterized by a high degree of linguistic diversity, and for about two and a half millennia Arabic has come into contact with various other Semitic languages, as well as with Indo-European languages and Turkish. Bilingualism, particularly with Aramaic, Kurdish, and Turkish, has resulted in numerous contact-induced changes in all realms of grammar, including morphology and syntax.
Perceived workplace adversity and the psychological wellbeing of correctional officers: examining the impacts and implications
Creators: name: Trounson, Justin Scott
Publisher: name: Swinburne
Year: 2024

description: This dissertation examined perceived workplace adversity and its effect on the psychological wellbeing of correctional officers. Results indicated that officers perceived a higher level of adversity than other occupations examined with the exception of police and emergency services. Officer-endorsed interpersonal, cognitive and behavioural response tendencies were identified and an empirical link between perceived adversity, psychological wellbeing and negative organisational impacts was established. Furthermore, the use of an Interpersonal/Solution-focussed (ISF) response style when faced with adversity reduced the impact of perceived adversity on psychological wellbeing. ISF strategies assist officers to maintain their wellbeing and reduce absenteeism, presenteeism and job dissatisfaction.

description: Khuzestan Arabic is an Arabic variety spoken in the southwestern Iranian province of Khuzestan. It has been in contact with (Modern) Persian since the arrival of Arab tribes in the region before the rise of Islam. Persian is the socio-politically dominant language in the modern state of Iran and has influenced the grammar of Khuzestan Arabic on different levels. The present article discusses phenomena of contact-induced change in Khuzestan Arabic and considers their limiting factors.
Finite element simulation of innovative manufacturing processes for tube fittings
Creators: name: Zhang, Yu
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 2008
Subjects: subject: Engineering, Mechanical.

description: Tube fittings are widely used in the pressure vessel industry. Current research on tube fittings serves to determine means of decreasing the cost and increasing the efficiency of their manufacture. With this motivation, several new tube forming processes have been proposed in recent years. The current study focuses on the finite element simulation of two new manufacturing processes for tube fittings; i.e. hydroforming and tube push-bending. For tube hydroforming, used to produce T and Y joints, there is a working range defined by the combination of internal pressure and axial load. To ensure that a satisfactory product is obtained, it is essential that the loading path be inside the working range. The working range for several tube hydroforming models are predicted, and the results are validated with existing theoretical and experimental values. The new tube push bending process has the advantage that tube bends with a small bending radius can be produced. In this study, finite element simulations are carried out to demonstrate this advantage. The spring-back and material waste factors are determined through simulation, as well as the maximum axial load. The results obtained are validated against existing theoretical and experimental values. The study ends with some conclusions about the suitability of finite element simulations in tube forming processes, and with some suggestions for further research.
Routing in wireless sensor networks: An ant-inspired approach

Subjects: subject: Computer Science.

description: The field of routing and sensor networking is an important and challenging research area of network computing today. Advancements in wireless sensor networks (WSNs) enable a wide range of environmental monitoring and object tracking applications. Routing in WSN is a challenging task. As the size of the network increases, routing becomes more complex. Therefore, biologically-inspired intelligent algorithms have been taken into consideration to address this problem. Ant routing algorithms have shown excellent performance when applied to WSN routing. This thesis presents routing algorithms in WSN, the current use of swarm intelligence for routing in WSN, explains different ant routing algorithms and shows why some existing ant routing algorithms do not work well for WSN. Consequently, we present four ant-colony based routing algorithms, which are suitable for WSN. Our proposed algorithms take into consideration the WSN requirements, including energy consumption, success rate, and time delay. In addition, one of our algorithms is a multimedia-enabled routing algorithm, which is suitable for single-source-to-single-destination multimedia data traffic to optimize different performance criteria, especially end-to-end delay and jitter. The last proposed algorithm is a many-to-one routing algorithm, which facilitates congestion avoidance in the network. The findings in this thesis are supported with several computer simulations.

description: This chapter investigates contact-induced changes in Anatolian Arabic varieties. The study first gives an overview of the current state and historical development of Anatolian Arabic. This is followed by a survey of changes Anatolian Arabic varieties have undergone as a result of language contact with primarily Turkish and Kurdish. The chapter demonstrates that the extent of the change varies from one dialect to another, and that this closely correlates with the degree of contact a dialect has had with the surrounding languages.

Subjects: subject: Engineering, Electronics and Electrical.

description: VPN technology is an attractive cost-effective solution for the support of the networking needs of enterprises. In this work, we review current issues in the development of VPN technology. We then focus our research on minimal cost design, used by network-based IP VPN service providers. The interest in such solutions is generated by both customers seeking to reduce support costs and by Internet Service Providers (ISPs) seeking new revenue sources. Solving the cost minimization would allow ISPs to define and deploy new VPN services. In this thesis, Multicommodity Min-Cost Flows (MMCF) formulations are applied to the resource allocation in network-based IP VPN, in order to develop a cost-effective routing proposal. Compared with RFC 2676, one of the Open Shortest Path First (OSPF) algorithms, various improvements in routing costs are obtained corresponding to different proposed network topologies.

description: Developing novel applications based on deep tech (ML, AI, HPC, quantum, IoT) and deploying them in production is a very painful, ad-hoc, time consuming and expensive process due to continuously evolving software, hardware, models, data sets and research techniques. After struggling with these problems for many years, I started the Collective Knowledge project (CK) to decompose complex systems and research projects into reusable, portable, customizable and non-virtualized CK components with unified automation actions, Python APIs, CLI and JSON meta descriptions. My idea is to gradually abstract all existing artifacts (software, hardware, models, data sets, results) and use the DevOps methodology to connect such components together into functional CK solutions. Such solutions can automatically adapt to evolving models, data sets and bare-metal platforms with the help of customizable program workflows, a list of all dependencies (models, data sets, frameworks), and a portable meta package manager. CK is basically our intermediate language to connect researchers and practitioners to collaboratively design, benchmark, optimize and validate innovative computational systems. It then makes it possible to find the most efficient system configutations on a Pareto frontier (trading off speed, accuracy, energy, size and different costs) using an open repository of knowledge with live SOTA scoreboards and reproducible papers. Even though the CK technology is used in production for more than 5 years, it is still a proof-of-concept prototype requiring further improvements and standardization. We plan to develop a user-friendly web front-end to make it easier for researchers and practitioners to create and share CK workflows, artifacts, SOTA scoreboards, live papers, and participate in collaborative, trustable and reproducible R&D.

Subjects: subject: Physics, Optics.

description: Static and modulated reflectance measurements were made on samples of some III-V compounds and their alloys. Multiplet structures resolved in the reflectance spectra of III-V compounds in the energy range 3.5--7.5 eV led to the determination of the spin orbit splittings Delta0', Delta 2, Delta1', DL3V and ▵L3C . Structure was observed in the thermoreflectance spectra of III-V compounds in the energy range 1.5--6.0 eV and it was assigned to interband transitions. Results enabled comparison with previous data obtained using other techniques. Static and modulated reflectance measurements confirmed the nonlinear variation of energy gaps with composition in GaxIn 1-xSb alloy. Similar data was obtained for InAs1-xP x and InSb1-xAsx alloys from electroreflectance measurements. Results on five III-V alloys were analysed, fitting a quadratic equation to the energy gap variation with composition curves. The total bowing parameters determined experimentally were compared with theoretical values. The spin orbit splitting Delta1 was also found to vary nonlinearly with composition in the five alloy systems investigated and the bowing parameters were related to the atomic spin orbit splittings of the alloying elements.

description: This paper assesses the combined effect of field plot size and LiDAR density on the estimation of four forest structure attributes: volume, total biomass, basal area and canopy cover. A total of 21 different plot sizes were considered, obtained by decreasing the field measured plot radius value from 25 to 5 m with regular intervals of 1 m. LiDAR data densities were simulated by randomly removing LiDAR pulses until reaching nine different density values. In order to avoid influence of the digital terrain model spatial resolution, eight different resolutions were considered (from 0.25 to 2 m grid size) and tested. A set of per-plot LiDAR metrics was extracted for each parameter combination. Prediction models of forest attributes were defined using forward stepwise ordinary least-square regressions. Results show that the highest R² values are reached by combining large plot sizes and high LiDAR data density values. However, plot size has a greater effect than LiDAR point density. In general, minimum plot areas of 500–600 m² are needed for volume, biomass and basal area estimates, and of 300–400 m² for canopy cover. Larger plot sizes do not significantly increase the accuracy of the models, but they increase the cost of fieldwork.
Experimental data acquisition and modeling of three-dimensional deformable objects using neural networks

Publisher: name: Université d'Ottawa / University of Ottawa

Subjects: subject: Engineering, System Science.

description: Nowadays there are many technologies and design tools available to accurately obtain and model the geometric shape and the color of objects. However, these methods are not able to provide any information about the elasticity of the objects. This thesis presents a general-purpose scheme for measuring, constructing and representing geometric and elastic behavior of deformable objects without a priori knowledge on the shape and the material that the objects under study are made of. The proposed solution is based on an advantageous combination of neural network architectures and an original force-deformation measurement procedure. An innovative non-uniform selective data acquisition algorithm based on self-organizing neural architectures (namely neural gas and growing neural gas) is developed to selectively and iteratively identify regions of interest and guide the acquisition of data only on those points that are relevant for both the geometric model and the mapping of the elastic behavior, starting from a sparse point-cloud of an object. Multi-resolution object models are obtained using the initial sparse model or the (growing or) neural gas map if a more compressed model is desired, and augmenting it with the higher resolution measurements selectively collected over the regions of interest. A feedforward neural network is then employed to capture the complex relationship between an applied force, its magnitude, its angle of application and its point of interaction, the object pose and the deformation stage of the object on one side, and the object surface deformation for each region with similar geometric and elastic behavior on the other side. The proposed framework works directly from raw range data and obtains compact point-based models. It can deal with different types of materials, distinguishes between the different stages of deformation of an object and models homogeneous and non-homogeneous objects as well. It also offers the desired degree of control to the user.
Three essays on monetary policy and economic growth in China

Publisher: name: Université d'Ottawa / University of Ottawa
Year: 2009
Subjects: subject: Asian Studies.
subject: Economics, General.

description: This dissertation consists of three essays that examine various important macroeconomic issues that are of concern to the Chinese economy. The analysis that supports the empirical work is inspired by post-Keynesian theory. The first chapter presents the mechanism of endogenous sterilization by extending the theory of demand-led money supply to the case of China. This view of money is confirmed by the fact that foreign reserves are not cointegrated with base money, meaning that there is no long-run relationship between foreign reserves and the supply of base money, whereas foreign reserves are long-run related with the claims of the central bank and the amount of bonds issued by the central bank. The second chapter outlines Kaldor's laws and tests for the contributions of the manufacturing sector to labor productivity and overall output growth using the panel dataset of 29 Chinese regions during the period of 1986-2007. Empirical findings, taking advantage of spatial panel econometric techniques, provide significant support for the Kaldorian thesis, while the incorporation of spatial autocorrelation improves the performance of empirical models compared to traditional ones. The third chapter analyzes the relationship between functional income distribution and Chinese economic growth from 1993 to 2007. Based on a demand-driven macroeconomic framework, there is a possibility of either profit-led or wage-led demand regime depending on the total effects of changes in the profit share on all components of final demand. Our results suggest that the Chinese economy presents a profit-led nature both for all 29 regions and for the coastal regions. We also find that while the expansion of interregional and international trade plays an important role, it is investment expenditure that determines the profit-led pattern of economic growth.

description: Les études concernant la diaspora somalienne et ses capacités de mobilisation dévoilent une communauté diasporique qui n'a encore pas formulé une perspective cohésive des nécessités en révélant qu'il n'existe toujours pas une identité collective entre les réalités distinctes et contrastantes des membres de la diaspora. Cette conception de l'état de conscience de la diaspora somalienne aujourd'hui est partielle et partiale puisque cette argumentation ne tient pas compte des activités et des projets mobilisant certains individus de la diaspora. Dès lors, cette recherche propose un survol des diverses modalités par lesquelles se manifeste l'engagement de la diaspora somalienne d'Ottawa pour les populations se trouvant en Somalie. Ensuite dans le même axe, on s'interrogera sur la manière dont s'articule la mobilisation et comment se présentent les cadres interprétatifs qui légitiment les actions individuelles ou collectives des Somalis appartenant à une nouvelle dynamique d'engagement typique à une diaspora transnationale. Le drame somalien, le traumatisme de la guerre et la dispersion des Somalis aux quatre coins du monde ont infligé des transformations fulgurantes à la culture et à la structure sociale des Somalis et cette thèse tentera de s'attarder sur les diverses modalités d'engagement de cette population à Ottawa.

description: In late 2019, a non-binding referendum on the future political status of Bougainville was held. A team of researchers from The Australian National University and the University of Papua New Guinea observed the referendum, including the polling and counting processes. The Bougainville referendum of 2019 was conducted in a social setting of great community involvement, with robust polling procedures and generally effective administration and implementation. Whilst there were some minor shortcomings in compliance and isolated security concerns, as an exercise in polling in a Melanesian context, it was exemplary. It met international standards of free, fair and credible polling practices. This In Brief will explore potential lessons from this referendum for future elections in Bougainville and elsewhere in Melanesia.

description: Unlike textual description, pathfinder network (an algorithm that results in a kind of concept map) provides a visual way to describe the knowledge structure of a student. It often provides a clear measure of the student's understanding and highlights the student's misconceptions. The traditional approaches of assessment such as multiple-choice questions and word problems often fail to identify these misconceptions. The following steps were carried out for this study. 1. The study assessed the knowledge structures of grade 11 physics students of a public high school of Ottawa and their instructor using pathfinder networks. The work concept (a subset of links around the concept of work) in the students' pathfinder networks was compared to the work concept in the referent network and the similarity between them was calculated. 2. During the intervention phase of the study, individualized instructions and exercises based on the misconceptions about the concept of work, shown by their knowledge structures, were given to the students. 3. The study again assessed the knowledge structures of the students for a change in work concept in their pathfinder networks by comparing it with the referent network. The study also analyzed the control concepts of "mass" and "gravity" in the pathfinder networks of the students and found no significant change in those. In addition to pathfinder networks' utility as a global measure of conceptual knowledge of the students, which is useful for summative assessment, this research is a step forward to provide evidence that an individual node in the pathfinder network can be explored to study a particular concept in the network. Therefore, the research demonstrates the potential utility of pathfinder networks for formative assessment. This offers the possibility of providing the students with extremely comprehensive feedback. Results revealed that the similarity index of work concept in the pathfinder networks of the students increased from pre- to post-intervention phase. Most likely, the major reason for this change was that individualized instructions were given to each student about the concept of work which stimulated and probably changed some of their misconceptions. To address validity, the similarity indices of mass and gravity concepts in the pathfinder networks of the students were also checked for improvement. The result shows that there is no significant improvement in mass and gravity concepts as the individualised instructions were not given to the students about mass and gravity concepts. Findings support the use of structural assessment of knowledge with pathfinder scaling technique for formative assessment as a way to enhance learning.
Diophantine approximation by conjugate algebraic numbers

description: In 1969, Davenport and Schmidt provided upper bounds for the approximation of a real number by algebraic integers. Their novel approach was based on the geometry of numbers and involved the duality for convex bodies. In the present thesis we study the approximation of a real number by conjugate algebraic numbers. We find inspiration in Davenport and Schmidt's method, but ultimately our approximations come from the theory of continued fractions. We get a general optimal result for which we offer two different proofs. We then extend two of Davenport and Schmidt's important results to the context of an imaginary quadratic number field. Our method follows that of Michel Laurent who simplified Davenport and Schmidt's argument in 2003. One of their original results is optimal and so is our extension.

description: Background. Herring roe is an underutilized source of n-3 polyunsaturated fatty acids (PUFAs) for human consumption with high phospholipid (PL) content. Studies have shown that PL may improve bioavailability of n-3 PUFAs. Arctic Nutrition’s herring roe product MOPL™30 is a PL: docosahexaenoic acid (DHA)-rich fish oil mixture, with a DHA:eicosapentaenoic acid (EPA) ratio of about 3:1, which is also rich in choline. In this pilot study, we determined if MOPL30 could favorably affect plasma lipid parameters and glucose tolerance in healthy young adults. Methods Twenty female and one male adults, between 22 and 26 years of age, participated in the study. Participants took encapsulated MOPL30, 2.4 g/d EPA + DHA, for 14 days, and completed a three-day weighed food record before and during the capsule intake. Plasma lipids and their fatty acid (FA) composition, plasma and red blood cell (RBC) phosphatidylcholine (PC) FA composition, acylcarnitines, choline, betaine and insulin were measured before and after supplementation (n = 21), and one and four weeks after discontinuation of supplementation (n = 14). An oral glucose tolerance test was performed before and after supplementation. Results Fasting plasma triacylglycerol and non-esterified fatty acids decreased and HDL-cholesterol increased after 14 days of MOPL30 intake (p < 0.05). The dietary records showed that PUFA intake prior to and during capsule intake was not different. Fasting plasma glucose was unchanged from before to after supplementation. However, during oral glucose tolerance testing, blood glucose at both 10 and 120 min was significantly lower after supplementation with MOPL30 compared to baseline measurements. Plasma free choline and betaine were increased, and the n-6/n-3 polyunsaturated (PUFA) ratio in plasma and RBC PC were decreased post-supplementation. Four weeks after discontinuation of MOPL30, most parameters had returned to baseline, but a delayed effect was observed on n-6 PUFAs. Conclusions Herring roe rich in PL improved the plasma lipid profile and glycemic control in young adults with an overall healthy lifestyle.

description: A three-dimensional numerical model was used to examine the turbulent flow field and associated sediment transport due to a series of barbs in a channel bend. It was observed that the results simulated by the model showed good agreement with measured data and adequately simulated the important features of sediment transport. Statistical analysis of the predicted and measured sediment transport results found an average regression coefficient of determination of 0.8 for the 90 and 135° channels. It was found that the predicted velocity data followed expected trends. The following objectives were achieved: validation of the application of a three-dimensional numerical model to bend sections of a channel containing barbs; simulation of the effects of different arrangements of barb groups; and analysis of the data to determine the relation of the flow field to associated scour and deposition in a complex fluvial environment. These novel data are useful for improved analyses of the bank protection capabilities of these structures and for the development and improvement of design guidelines.

description: The impact of recent climate change on permafrost distribution was evaluated by repeating the 1964 survey of Roger Brown along the Alaska Highway from Whitehorse, YT to Fort St. John, BC in August 2007 and 2008. Results demonstrate that: (1) significant degradation of permafrost has occurred over the past four decades, especially in the southernmost part of the route where 67% of the permafrost sites in 1964 no longer exhibit perennially frozen conditions; (2) the mapped southern limit of discontinuous permafrost appears to have shifted roughly 75 km northward; (3) most of the permafrost still present in the study area is in peat or under thick organic mats, which probably relates to a large thermal offset or to the latent heat requirements of thawing permafrost; and (4) that where permafrost has persisted, it is very thin, discontinuous, at temperatures just below 0°C, and its location may relate in part to the existence of atmospheric temperature inversions in the region. Changes in permafrost are attributed to significant climatic warming, primarily in winter, at rates of 0.4°C to 0.5°C per decade from 1965-2008. The results augment the very limited number of field studies of long-term change to permafrost in Canada, and are relevant to northern residents who must adapt to changing permafrost conditions.
Applied time series analysis for forecasting process cycle times and process yields in the semiconductor manufacturing industry.

description: Complementary metal oxide semiconductor (CMOS) integrated circuits (ICs) are the dominant technology in the semiconductor industry. Meeting delivery date is important to ensure customer satisfaction and maintain momentum between manufacturing divisions. Two major concerns are to produce the right quantity of ICs in the expected period of time. Yield and cycle time are two critical parameters used to assess process performance. The main objectives of this work were to obtain reliable forecasts of yields and cycle times and to monitor the process for detection of upsets. We explored the use of time series models such as ARIMA, transfer function and intervention models. A simultaneous outlier treatment and forecasting strategy was developed which combined the joint estimation of model parameters and outlier effects procedure with some new control charts. This method is particularly suited for highly correlated processes that are frequently subjected to large outliers. Choice of time basis was an important issue in this work (i.e., week of emergence from or entrance to the process). For ARIMA modeling, cycle time series were found to follow a highly correlated AR(1) process whereas yield series were just white noise. Five-step ahead ARIMA forecasts were often inaccurate due to the presence of frequent and large outliers. One step-ahead ARIMA forecasts were quite satisfactory. Transfer function models relating yield data to the process capacity data were built. Transfer function models for overall process cycle times were constructed using as inputs cycle times for various stages in the process. Five step-ahead forecasts were highly improved using these transfer functions. (Abstract shortened by UMI.)

description: Background: Although rates of tobacco use and exposure to second-hand smoke (SHS) are declining in Canada, SHS exposure among non-smoking adolescents remains high. This study aimed to describe frequency, locations, and avoidance behavior related to SHS exposure among adolescent girls in British Columbia, Canada. Methods: Data were analyzed from 841 adolescent girls aged 13 to 15 years old who completed an internet-delivered survey as part of a cohort study examining SHS exposure and substance use. Measures assessed demographics, smoking behavior and intentions, frequency and locations of SHS exposure, and avoidance behavior related to SHS. Results: Excluding their own smoking, 27% of girls reported exposure at least once a week and an additional 17% reported daily or almost daily exposure over the past month. Among girls who reported daily or almost daily exposure, the locations of most frequent levels of high exposure were in the home, at or near school, inside a vehicle, and outdoor public places. Avoidance behavior related to SHS exposure significantly differed by overall SHS exposure in the past month. Conclusions: Despite historically low smoking rates, many adolescent girls continue to report regular SHS exposure in multiple locations in British Columbia. Girls with the most frequent exposure were significantly less likely to report habitual avoidance behavior related to SHS compared to those less frequently exposed. This study elucidates settings of high SHS exposure among adolescent girls that could be targeted in future policy interventions. Additionally, future interventions could target adolescent girls who are frequently exposed to SHS and report infrequent avoidance behavior around their SHS exposure.

description: What of the mother/whose house is in flames/ and both of her children/ are in their beds crying/and she loves them both/with the whole of her heart/but she knows she can only/carry one at a time? School Night-Ani DiFrancoPour observer la moralite en profondeur, Nietzsche produit une analyse genealogique des entrecroisements et des transformations du fort et du faible concus dans la perspective de la volonte de puissance. Cette etude s'interesse aux analyses developpees par G. Deleuze et T. B. Strong a propos de l'opposition entre fort et/ou faible. Il s'agit, en opposant ces deux interpretations, de determiner le sens de ces concepts nietzscheens. Est-ce le fort ou le faible, alternative tranchee, ou le fort et le faible, combat interieur? Cette discussion adhere a la seconde conception, celle de Strong. De la, elle entrevoit une vision politique de la recherche pour l'harmonie humaine dans la surhumanite qui lutte pour maintenir l'equite.But then what kind of scale / compares the weight of two beauties /the gravity of duties /or the ground speed of joy? / tell me what kind of gauge /can quantify elation? / what kind of equation/could I possibly employ?

title: The Use of a Modified Stroop Task to Assess Attentional Biasing Related to Adult Attachment Classification

description: Adult attachment styles can be thought of as representational schemata for how an individual interprets other people's actions, relationships, and emotions in close relationships. This study utilized an emotional Stroop task that consisted of different word/letter stimuli to investigate the effect of attentional biasing, in the form of the interference effect, on reaction times. Five measures of adult attachment were used that varied based on whether attachment was categorized or placed on a dimension. Contrary to expectation, insecurely attached individuals did not have longer reaction times on negative stimuli; however, negative word stimuli did cause an interference effect relative to neutral and letter string stimuli for all participants. A sentence completion priming task which allowed for self-relevant relationship priming was also administered. No differences on reaction times were found for participants who were primed and participants who were not primed. Although a relationship between adult attachment style and attentional biasing on the Stroop was not found, further research is necessary.
Managing stakeholder 'push back': an exploratory investigation into dealing with negative cross cultural communication in a global environment

description: This paper addresses the issue of a current business phenomenon – ‘push back’. This phenomenon has been experienced by a number of transnational companies. It is embedded in the challenges of cross-cultural communication and involves the linkage of local culture activists with globalisation acitivists in an alliance to stop business growth. This exploratory investigation examines three multinational organisations using qualitative research. From the findings a model has been developed in an attempt to provide practitioners with a framework with which to understand ‘push back’. The complexity of combating alliances of this nature raises challenges for the current approaches to marketing and the need for a multi-stakeholder approach in cross-cultural communication is suggested.
Agent-based service discovery in ad-hoc communications environments

description: Service Discovery allows for the automatic and spontaneous discovery and configuration of network services. It is especially important in ad-hoc environments where the network topology is unpredictable. We propose the use of Agent Technology, an efficient and convenient technology, in our work to shed new light in this area. Our first model takes on a centralized architecture. One agent in the network, the Service Discovery Agent (SDA), assumes the responsibility of maintaining the central service repository. Each service and user has their own agents which we name Service Agents (SAs) and Personal Agents (PAs) respectively. SAs are responsible for registering and deregistering their services with the SDA. Our second discovery model uses a distributed architecture that can operate in a fully dynamic environment. For this we use an existing probabilistic P2P search algorithm as a basis. Discovery is performed on demand using the concepts of the P2P search algorithm. The algorithm is enhanced in many ways so that it is adapted to an ad-hoc environment while still keeping the basic efficient operations. As more searches are performed, devices become more knowledgeable and discovery performance would improve. (Abstract shortened by UMI.)
