description: Understanding the spatial ecology and habitat use of declining species is essential for their management and successful recovery. I examined the movement patterns and habitat selection of map turtles (Graptemys geographica), a species at risk, in St. Lawrence Islands National Park. Adult females moved longer distances and had larger home ranges than juvenile females and males. The longest distances moved by adult females occurred during nesting excursions. Examining movements allowed for critical habitat locations to be found (nesting sites, hibernacula). My data on movements will allow St. Lawrence Islands National Park to mitigate development plans and regulate visitor impacts on these sites. I examined habitat selection at multiple spatial scales. Map turtles generally avoided deep water (>2 m) and selected home ranges in waters <1 m deep with significantly more natural than developed shoreline. Adult females used deep water more often and males preferred areas with surface cover. Management effort should implement regulations concerning further shoreline development.
Rural economic revitalization in Japan through 'economic gardening'
Creators: name: Yamamoto, Takashi
Publisher: name: Swinburne

description: The 'Economic Gardening' is a practical approach for local economic development first employed in Littleton, Colorado, USA in 1989. The approach emphasizes on economic development efforts on investing in local businesses rather than traditional approach of attracting big firms to the local community by offering incentives and tax breaks. The Economic Gardening program focuses on providing market information for local business to increase their competitiveness and the probability of success. Another pillar of the program is paying attention to infrastructure to create a city where entrepreneurs want to live and people want to do businesses. The third emphasis is to build connections among the businesses in the city by facilitating industry clusters and cross-marketing opportunities, and strengthening connections between industry and the higher education sector. Ohgata Village in Akita Prefecture, one of the rural municipalities in Japan, has been employing similar strategy to the Economic Gardening. Having highly specialized in rice production, the village promoted a 'produced locally, consumed locally' policy, public-private partnership in agriculture, developed infrastructure, and initiated internship and entrepreneurship programs in cooperation with personnel service firms in Tokyo. This is an innovative approach in rural Akita, where it is recognized as the least entrepreneurial in Japan.

description: The purpose of the study was to document the process of Triathlon Canada's implementation of a new coach education program in the competition-development context. Two conceptual frameworks were used for the study, the first was the OECD (2007b) qualifications system framework and the second was Jarvis' (2006a) conception of a biography. In part 1, the high performance director was interviewed four times throughout the year to get his perspective on the process of developing and implementing the new program. Through the use of purposeful sampling, all of the coaches' (n=10) actively coaching triathletes in the competition-development context in Canada were interviewed in order to explore the different experiences and qualifications they had, prior to their entry into the program. In part 2, one interview was conducted with the first coach to be evaluated on the Design a Sport Program outcome, and one interview was conducted with each of the two evaluators. The results were divided into two parts; in part 1, it was evident based on the interviews with the high performance director that his unique academic and professional background influenced him to develop a program tailored to the experienced coaches participating in the new program. Furthermore, interviews with the participants' revealed biographies that indicated they were: (a) well educated, (b) held multiple coaching certifications, (c) had rich athletic and coaching experiences, and (d) approached learning through diverse means, including formal, non-formal, and informal learning situations. These interviews revealed that the evaluation process was a learning experience for both the coach and the evaluators. Furthermore, there were elements within the new program that seemed to be conducive to lifelong learning. In conclusion, results from the study suggest that it is important to consider the biography of the participants because it will influence how they approach learning. As such, the development and delivery of coach education programs in the competition-development context will likely vary for each national sport federation.

description: Exercise has been considered important in the management of functional balance problems although there are limited data supporting effectiveness after traumatic brain injury (TBI). This thesis compared two functional balance retraining programs: a virtual reality (VR) generated program and an activity-based (AB) program. Participants (n = 33, age 18--66) had sustained a moderate or severe TBI (initial Glasgow Coma Scale [GCS] <12) 6 months or more before the start of the study. Participants were quasi-randomly assigned to either an intervention group or a control group that received no intervention. Groups were matched on initial Berg Balance Scale scores (BBS), years since TBI, and age. Static standing balance (using a force plate), functional balance (using the Community Balance and Mobility Scale [CB&M]) and perceptions of balance and function (using the Activity-specific Balance Confidence Scale [ABC] and the Lower Extremity Functional Scale [LEFS]) were measured at baseline, after six weeks of intervention, and 3 months later. BBS and CB&M scores improved for the exercise groups after six weeks. Some of the improvements were still present at three months. Functional balance improvements were supported by increased scores on the ABC, the LEFS, and by participant focus group comments. The focus groups also indicated the multidimensional benefits of both types of exercise. While not statistically significant, the VR group reported higher scores of functional balance and mobility, balance confidence, and more positive comments from participants than the AB group. This supports the use of VR as a potentially effective method of delivering exercise.
Measurement of the information for identification in iris images

Subjects: subject: Engineering, Electronics and Electrical.

description: Performance of iris recognition systems strongly depends on uniqueness of irises. One possible way to estimate the uniqueness is to measure the amount of identifying information contained in irises. No proper identification can be done if the quality of involved samples is poor. In our study, we verified human ability to assess iris sample quality and concluded that their intuitive quality assessment may not be sufficient for biometric identification applications. After image quality is assured, the biometric information measurement may be addressed. We studied the approach proposed by Daugman that measures the amount of information in irises. Experiments and statistical analysis showed that it does not provide a useful way to measure an amount of identifying information. An alternative algorithm based on relative entropy was developed to measure information important for identification. We used it to detect the most informative regions of the iris and to understand dependencies within it.
Taxonomic revision of the genera Achiroides, Brachirus, Dexillus, and Paradicula (Pleuronectiformes: Soleidae)
Creators: name: Lapierre, Krystal-Lynn
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 2007
Subjects: subject: Biology, Zoology.

description: The objective of this study was to taxonomically revise the 41 nominal species found within the Brachirus species complex (Order Pleuronectiformes; Family Soleidae). This complex is recognizable by a combination of characters: the structure of the supracranial portion of the dorsal fin which lack pterigiophores with their proximal ends directly over the cranium, by the joined dorsal, anal and caudal fins, and by the anterior tip of the dorsal fin almost reaching the upper jaw. This revision is based on the morphological and meristic examination of 34 type and 717 non-type specimens for all available nominal species. The type material was examined for twenty species. The remaining species were assessed from the original type description. It was found that the Brachirus species complex is made up of four genera including 19 valid species: Brachirus (14), Achiroides (1), Dexillus (3), and Paradicula (1). Eight of the nominal species do not belong to the Brachirus species complex and have been removed from the scope of this study. Achiroides, characterized by the rudimentary pectoral fins, contains a single valid species, A. melanorhynchus (Bleeker 1851) and three synonyms (Synaptura aenea Smith 1931, Anisochirus harmandi Sauvage 1878, and Plagusia leucorhynchos Bleeker 1851). Dexillus , characterized by the close proximity of the eyes, contains three valid species: D. macrolepis (Bleeker 1858), D. megalepidoura (Fowler 1934), and D. muelleri (Steindachner 1879). D. muelleri is a senior synonym of the nominal species Synaptura arafurensis Gunther 1880. Paradicula, unique in having the gill openings restricted to the base of the pectoral fins, contains a single valid species, P. setifer Paradice & Whitley 1927. The remaining Brachirus species cannot yet be defined as being monophyletic. Brachirus contains 14 valid species: B. aspilos (Bleeker 1852) (synonyms: Synaptura heterolepis Bleeker 1856, S. marmorata Bleeker 1853, and S. sorsongonensis Evermann & Seale 1907), B. sundaicus (synonyms: Bleeker 1870--75) (Synaptura cinerea De Vis 1883 and S. nigra MacLeay,1880), B. selheimi (Macleay 1882) (synonyms: B. salinarum Ogilby 1910, and Synaptura villosus Weber 1907), B. foliacea (Gunther 1862) (synonym: Synaptura filamentosa Sauvage 1878), B. siamensis (Sauvage 1878) (synonyms: Synaptura krempfi Durand 1940 and Chabanaudetta smithi Joglekar 1971), B. breviceps Ogilby 1910, B. cinerascens (Gunther 1862), B. fitzroiensis (De Vis 1882), B. orientalis (Bloch & Schneider 1801), B. pan (Hamilton 1822), B. panoides (Bleeker 1851), B. dicholepis Peters 1877, B. swinhonis Steindachner 1867, and B. canus Gray 1854. An identification key of valid species belonging to the Brachirus species complex is provided.
Pragmatically understanding stakeholder relationships and action

Publisher: name: Swinburne
Year: 2024

description: Stakeholder research attempts to address the role and impact of stakeholder relationships in organizational life. Stakeholders act in response to an issue that arises in the relationship with the organization. Using the example of Bioreg, an organization that manages approvals for genetically modified organisms, we explore the role of the impact of an issue on stakeholder mobilization. Organizations are, in general, more adept at dealing with the 'rational' interest-based actions of stakeholders but are not well equipped for responding to identity-based stakeholder responses, yet the threshold for identity-based mobilization is lower than that for interest-based action. Based on the Issue-Impact-Action framework, suggestions are proposed for appropriate stakeholder management strategies for each mode of stakeholder response.
Les soins infirmiers en milieu de désintoxication: Entre soins et contrôle social

Subjects: subject: Health Sciences, Nursing.

description: Dans le cadre d'un traitement des dépendances, les infirmières jouent un rôle important (Rassool & Villar-Luis, 2004). Chaque jour, elles composent avec une clientèle non seulement en situation de sevrage mais aussi gravement malade sur les plans physique et psychologique (Naegle & Erickson D'Avanzo, 2001). La recension des écrits rapporte peu de recherches sur les rôles exercés par les infirmières em milieux de désintoxication. En effet, les infirmières doivent articuler des fonctions visant à maintenir l'ordre allant même jusqu'à la mise en oeuvre d'un traitement forcé ou fortement suggéré par des instances juridiques (Thomas 2005). Or certains articles sur le sujet mentionnent le besoin d'offrir au client "un encadrement" afin de lui permettre de suivre son traitement ou de cesser sa consommation. Bien que la nécessité d'un encadrement strict ait été évoquée, aucune recherche sur cet aspect de la pratique infirmière dans ce type de milieu n'est documentée dans les écrits consultés. Étant donné que l'unité de désintoxication est fortement investie par une régulation comportementale, il est nécessaire de s'attarder non seulement à l'angle caritatif de l'exercice infirmier mais aussi aux aspects politiques du soin. Les rapports de pouvoir entre le personnel infirmier et les personnes admises en désintoxication constituent donc la pierre angulaire de cette recherche. Dans la mesure ou les aspects politiques du soin sont au coeur de cette recherche, notre choix de cadre théorique s'est arrêté sur les travaux de Michel Foucault. Plus spécifiquement, notre analyse foucaldienne s'appuiera sur le concept de pouvoir disciplinaire afin de supporter notre recherche au plan théorique. Au plan méthodologique, un devis qualitatif a été privilégié. Les résultats de cette recherche montrent que le soin infirmier dans une unité de désintoxication est assorti de composantes caritatives et disciplinaires qui se juxtaposent continuellement. Les infirmières qui ont participé à cette étude ont clairement exprimé qu'il leur serait impossible de soigner la clientèle sans la structure, les mécanismes de contrôle et les mesures disciplinaires dont elles disposent. L'examen des données de l'observation du milieu et des documents écrits a corroboré l'existence de telles pratiques, qui sont entérinées, du moins en partie, par la direction sous formes de politiques et procédures.
Kinetics and mechanism of alpha-chymotrypsin catalyzed reactions.

Subjects: subject: Chemistry, Organic.

description: The principle of microscopic reversibility was formulated for elementary reactions at equilibrium. It follows from the principle that for any elementary reaction the favored reaction path in one direction must be the reverse of that in the opposite reaction, and that the ratio of rate constants is the equilibrium constant. The same is true for non-chain reactions occuring under steady-state conditions provided that the alternative paths are equivalent as far as kinetic order is concerned. For reactions occurring under non-steady-state conditions, for chain reactions even in the steady state, and for non-chain reactions in which the alternative paths are not kinetically equivalen, the preferred reaction path in one direction may be different from that in the other; in such cases the ratio of the over-all rate constants is not equal to the equilibrium constant. The principle of microscopic reversibility can never be used to prove the mechanisms of a reaction when that for the reverse reaction has been established; it can only be used to eliminate kinetically equivalent mechanisms which are not the exact reverse of that for the reaction in the opposite direction.

description: Since the consumer prices skyrocketed in 2007, prices have been regularly monitored to anticipate potential impact of communities’ welfare. As part of this, there have been concerns that remote communities have been particularly affected by higher prices due to the effect of higher transportation costs or even the possibility that retailers may have spatial market power. Thus, the purpose of this study is to analyse whether remote rural areas in Scotland suffer of food prices that are higher than the country’s average prices. The methodology comprised in constructing expensiveness indexes for the basket of food purchased by a household computed following Aguiar and Hurst (2007) approach and considering 2,583 households from a scanner panel dataset for 2018. These indexes were then regressed -using weighted least squares- against several socioeconomic and demographic variables. The results indicate that according to the expectation food prices paid in remote rural areas are higher than the average prices in Scotland. Younger and older people pay higher prices and being those around 40 years old who pay the least. Moreover, households with children and led by women pay lower prices. Finally, the higher the shopping intensity (in terms of trips) the lower the prices paid. These results not only have implications for rural areas but also for a growing older population.

description: Women play an imperative role in the economic strengthening and sustainability of the agricultural sector, yet very little economic research documents the role and contribution of farming women in developed countries. Through an interdisciplinary systematic literature review of 184 international peer-reviewed, English-language studies between 1970 and 2020 we identify the effect gendered discourses have elicited within developed countries and present how this has shaped women’s economic contribution and visibility within UK agriculture. The study reveals key economic differences both between men and women, and within women as a group, with factors such as access to land, education, organisation and policy driving these differences. Strategies impacting women’s economic agency are also evaluated in the context of wider policy. The outcomes of this study increase understanding of factors shaping women’s economic contribution and visibility in UK agriculture and will inform further research investigating female participation in agricultural business management and decision making.
L'histoire de la vie privée au Canada entre 1960 et 1990: Les perspectives des ministres et des députés de la Chambre des communes sur la vie privée

description: Le droit de la vie privée au Canada est-il reconnu comme un droit fondamental par les ministres et les députés de la Chambre des communes? C'est la question que nous étudions ici en écrivant l'histoire des perspectives des ministres et des députés de la Chambre des communes concernant la vie privée, telles qu'enregistrées entre 1960 et 1990 dans les Comptes rendus officiels des Débats de la Chambre des communes. Pour y répondre, nous étudions en premier lieu la conception qu' avaient les ministres et les députés de la Chambre des communes de la question de la vie privée et la valeur qu' ils lui accordaient. Nous examinons ensuite la façon dont fut tracé l'équilibre entre le droit à la vie privée et les valeurs concurrentes. Par valeurs concurrentes, nous voulons dire la protection de la sécurité nationale, le maintien de l'ordre public et l'amélioration de l'efficacité administrative du gouvernement du Canada. En gros, nous avons trouve qu'entre 1960 et 1990, les ministres et députés de la Chambre des communes reconnurent la vie privée non seulement comme un droit, mais également comme un droit essentiel au citoyen et à la société démocratique. À cet égard, la Chambre promulgua diverses lois pour protéger ce droit, mais elle n'inclut pas de façon explicite le droit du citoyen à la vie privée dans la Charte des droits et libertés. Or, comment reconnaître le droit à la vie privée comme un droit fondamental compte tenu du fait que le gouvernement ne l'enchassa pas, en 1982, dans la Charte canadienne des droits et libertés, document réservé à la protection des droits fondamentaux? Ces questions sont, dans cette thèse, étudiées en cinq étapes: le contexte entourant les débats; le courant idéologique de la Chambre des communes; les débats sur l'écoute électronique; les débats sur la protection des renseignements personnels; et, enfin, l'exclusion d'une clause explicite sur la vie privée dans la Charte canadienne des droits et libertés.
Reason in the rhyme: The translation of sound and rhythm in children's books

description: Because child readers are still in the process of fully acquiring their language, children's books and their translations are closely linked to orality and the oral culture. Strong sound, rhyme and rhythm, which are habitual features of children's literature, also figure as important agents in the acquisition of language. Therefore, these linguistic principles might indicate a pedagogical skopos in the translation of children's literature, that of aiding in child language acquisition. Theory on sound translation and commentaries from translators of children's literature provide arguments for the importance of retaining sound and rhythm in translation. Analyses of three French-Canadian children's books translated into English provide practical observations of how sound and rhythm are translated in actual texts.

description: The Open Force Field Initiative (openforcefield.org) is developing a machinery to automatically parameterize molecular mechanics force fields. An important part of this process will be automating chemical perception — the way force field parameters are assigned to a molecule based on chemical environment. We created the SMIRKS Native Open Force Field (SMIRNOFF) format which allows for changes to easily be made in both the chemical perception and quantitative parameter space. In this presentation, I will share the motivation and success of the SMIRNOFF format, as well as my work on ChemPer, an open source tools for automatically creating SMIRKS patterns from molecular fragments.
Performance evaluation of congestion control protocols and loss differentiation algorithms over wireless networks

Subjects: subject: Engineering, Electronics and Electrical.

description: Congestion control protocols for wireless networks must be efficient, TCP-friendly, and robust to random wireless loss. Based on these criteria we have evaluated several different congestion control protocols, such as TCP Westwood, TFRC, MULTFRC, RAP, and IFTP. In wireless network environments, most of these protocols do not work well since wireless losses are counted as congestion losses. Therefore, it is necessary to extend these congestion control protocols with end-to-end Loss Differentiation Algorithms (LDA). We evaluate several existing LDA schemes, including Biaz, mBiaz, Spike, ZigZag, ZBS, PLC, SPLD, and TD, with simulation results showing different drawbacks for each scheme. We thus propose a new LDA scheme: the mSpike scheme. The mSpike scheme classifies the loss type according to the mean and deviation of the relative one-way trip time. The simulation results show that the mSpike scheme has better performance and fewer problems in most of the situations evaluated. We also test the combination of MULTFRC and mSpike under different wireless lossy environments. The simulation results show that they have a high utilization of the available bandwidth. Therefore, this combination would be a good choice for applications with high bandwidth requirements.

description: Implementation of fault testing environment for embeded cores-based digital circuits is a challenging endeavor. The subject thesis aims developing techniques in design verification and test architecture utilizing well-known concepts of hardware and software co-design. There are available methods to ensure correct functionality, in both hardware and software, for embeded cores-based systems but one of the most used and acceptable approaches to realize this is through the use of design for testability. Specifically, applications of built-in self-test (BIST) methodology in testing embeded cores are considered in the thesis, with specific implementations being targeted towards ISCAS 85 combinational benchmark circuits. Experimental results provided in the thesis prove the validity and importance of the approaches proposed for the design verification and test based on hardware and software co-design concepts utilizing Altera MAX Plus II simulation environment.

description: Legislators in the EU have long been concerned with the environmental impact of farming activities. As a means to mitigate adverse ecological effects and foster desirable ecosystem services in agriculture, the EU introduced so-called agri-environment schemes (AES). This study suggests a machine learning method based on generalized random forests (GRF) for assessing the environmental effectiveness of such agri-environment payment schemes at the farm-level. We exploit a set of more than 130 contextual predictors to assess the individual impact of participating in agri-environment schemes in the EU. Results from our empirical application for Southeast Germany suggest the existence of heterogeneous impacts of environmental subsidies on mineral fertiliser quantities, greenhouse gas emissions and crop diversity. Individual treatment effects largely differ from traditionally used average treatment effects, thus indicating the importance of considering the farming context in agricultural policy evaluation. Furthermore, we provide important insights into the optimal targeting of agrienvironment schemes for maximising the environmental efficacy of existing policies.
Identification of genetic loci that modulate cell proliferation in the adult rostral migratory stream using the expanded panel of BXD mice
Creators: name: Poon, Anna
name: Goldowitz, D.
Publisher: name: BioMed Central
Year: 2016

description: Background: Adult neurogenesis, which is the continual production of new neurons in the mature brain, demonstrates the strikingly plastic nature of the nervous system. Adult neural stem cells and their neural precursors, collectively referred to as neural progenitor cells (NPCs), are present in the subgranular zone (SGZ) of the dentate gyrus, the subventricular zone (SVZ), and rostral migratory stream (RMS). In order to harness the potential of NPCs to treat neurodegenerative diseases and brain injuries, it will be important to understand the molecules that regulate NPCs in the adult brain. The genetic basis underlying NPC proliferation is still not fully understood. From our previous quantitative trait locus (QTL) analysis, we had success in using a relatively small reference population of recombinant inbred strains of mice (AXBXA) to identify a genetic region that is significantly correlated with NPC proliferation in the RMS. Results: In this study, we expanded our initial QTL mapping of RMS proliferation to a far richer genetic resource, the BXD RI mouse strains. A 3-fold difference in the number of proliferative, bromodeoxyuridine (BrdU)-labeled cells was quantified in the adult RMS of 61 BXD RI strains. RMS cell proliferation is highly dependent on the genetic background of the mice with an estimated heritability of 0.58. Genome-wide mapping revealed a significant QTL on chromosome (Chr) 6 and a suggestive QTL on Chr 11 regulating the number of NPCs in the RMS. Composite interval analysis further revealed secondary QTLs on Chr 14 and Chr 18. The loci regulating RMS cell proliferation did not overlap with the suggestive loci modulating cell proliferation in the SGZ. These mapped loci serve as starting points to identify genes important for this process. A subset of candidate genes in this region is associated with cell proliferation and neurogenesis. Interconnectivity of these candidate genes was demonstrated using pathway and transcriptional covariance analyses. Conclusions: Differences in RMS cell proliferation across the BXD RI strains identifies genetic loci that serve to provide insights into the interplay of underlying genes that may be important for regulating NPC proliferation in the adult mouse brain.

description: This thesis provides an economic and mathematical framework, and the computing tools to compare the effects, costs and incremental cost-effectiveness of acute or preventative interventions for cardiovascular disease. A Finite Space Markov Chain Decision Analysis Model is designed by integrating a Decision Trees Model and a Markov Chain Model. The model and Cost-Effectiveness Analysis are implemented by using SAS/IML both on a PC with one processor and on a machine with multiple processors of the High Performance Computing Virtual Laboratory. A sample case with four states and eight intervention policies is studied to illustrate the framework, which is composed of (1) life path simulation, (2) cost and effectiveness estimation, (3) cost-effectiveness analysis, (4) sensitivity analysis, and (5) performance analysis on different platforms. Solution of delay effects, correlation among risk factors, and fluctuation in discount rate are viewed as limitations of the thesis and rewarding areas for further research.
Vision-based markerless three-dimensional human-arm tracking

Subjects: subject: Engineering, Electronics and Electrical.
subject: Computer Science.

description: Vision-based human motion tracking has been used in surveillance, human-machine interfaces in robotics and automation, virtual reality applications and biomechanics. Most techniques require markers, use a predefined motion sequence or user-intervention for initialisation, and do not process in real-time. This thesis describes a vision-based non-invasive technique for markerless real-time tracking of human-arm motion. Human-arm motion is tracked by processing images from two calibrated cameras in real-time, to estimate the positions of the joint centres of the wrist and elbow in three dimensions (3D), and to compute the 3D positions of the index finger and thumb in order to permit determination of the orientation of the hand. The hand-arm motion tracking is implemented in a human-robot interface in performing tasks of picking up an object and placing it at a target location. Tracking of the hand and arm is carried out without any prior knowledge of subject's arm length, color, width and distance from the cameras.

description: This paper adopts a political and class-based approach to examine three different British newspapers, The Times of London, The Manchester Guardian, and The Daily Herald in terms of their treatment of Austria-Hungary and Serbia in the month prior to the First World War. It questions how a newspaper's particular bias affects the way it discusses a topic, disseminates news, and relates with its audience. It examines the influence a newspaper has on shaping public opinion concerning friendly and enemy nations in the lead up to a war. At the same time this paper also examines how a newspaper's class and political background determines the level of support the paper demonstrates for war or for pacifism.
Efficient load balancing techniques for Real-Time RTI-based large-scale distributed simulation systems

Publisher: name: Université d'Ottawa / University of Ottawa
Year: 2008
Subjects: subject: Computer Science.

description: The Real-time extension of the High Level Architecture (HLA) is very essential and useful for many large-scale distributed simulation systems. Most previous attempts to design the Real-Time Run Time Infrastructure (RT-RTI) have enabled the usage of supported scheduling and prioritization services from underlying Real-time operating systems (RTOSs) augmented by communication QoS mechanisms. In this thesis, we wish to build on this functionality by proposing an algorithm that differentiates services processing within the RTI itself by incorporating resources' load balancing mechanisms with several scheduling and allocation policies. We focus our efforts on making the RTIs internal operations organized and well suited to the tasks and services it will be providing throughout the lifetime of HLA-compliant federations. The load-balancing mechanisms incorporated within the proposed system have been designed to build an efficient management scheme of the available processing resources. The proposed design have been heavily verified and tested from all related perspectives under the constraints of the Discrete Event System Specification (DEVS), especially the (RT-DEVS). This formalized system design approach have propagated a totally-new RT-RTI design that solves most of the shortcomings demonstrated and shown by previous designs. We have proved through our analytical performance evaluation and simulation experiments that our proposed real-time RTI framework exhibits a better performance in all terms, especially in the number of tasks served within deadlines when compared with existing RT-RTI frameworks. Our simulation results from the design model of the RT-DEVS formalism have verified the experimental results of the real implementation of the proposed RT-RTI design. In addition, these simulation models are capable of predicting key factors that may affect the performance of the RT-RTI core system, and could be used as guidance in searching for the optimal design.

description: Traditionally, researchers have defined entrepreneurship in terms of the entrepreneur---the individual who exploits a previously unnoticed opportunity. Entrepreneurship research thus focused on the attributes of the person and how these might be related to exploiting opportunities which others either didn't see or chose not to pursue. However, this individual level of analysis can prevent researchers from understanding entrepreneurial activity taking place at more collective levels of analysis. For example, concepts such as intrapreneurship (Burgelman, 1983) and entrepreneurial orientation (Dess, Lumpkin, & Covin, 1997) demonstrate researchers' interest in examining entrepreneurship at the organizational level of analysis. The current study extends this notion of entrepreneurship at collective levels of analysis by exploring the entrepreneurial activities of alliances between two companies. Lubatkin et al., (2001) call these types pf partnerships reciprocal learning alliances and suggest they are more entrepreneurial in nature than alliances formed to transfer already existing knowledge. Another limitation to the classic literature's focus on the individual entrepreneur is that it does not acknowledge the context within which entrepreneurship takes place (Shane, 2003; Shane & Venkataraman, 2000). Shane encourages researchers to view entrepreneurship as the nexus between the entrepreneur and the context within which opportunities are being identified and exploited. The current study explicitly acknowledges context by investigating the role social capital plays in engendering entrepreneurial activities within the studied alliances. In particular, we used the three dimensions of social capital identified by Nahapiet and Ghoshal (1998) -- structural, cognitive, and relational---as a broad framework to guide the research. The purpose of the research thus was to address the research question of how does social capital affect the entrepreneurial activities of reciprocal learning alliance partners.

description: Using cross-sectional data from 835 rice-farming households in Senegal, we investigated the extent to which membership in farmers’ cooperatives affects farm technical efficiency. To do so, we combine the propensity score matching method with the sample selection stochastic frontier model (Greene, 2010) and the stochastic meta-frontier approach (Huang et al., 2014). The propensity score matching helps in mitigating biases from observable variables. The sample selection stochastic frontier framework was used to control for biases arising from unobserved characteristics in the production frontier. Using the meta-frontier approach, farmers’ technical efficiency were estimated and compared. Results show that cooperative membership contributes significantly in improving rice production. However, when considering group-specific frontiers (farmers operating in their own benchmark: members vs non-members), cooperatives members do not technically perform better than non-members. Furthermore, when considering the meta-frontier estimates, significant differences in technical efficiency between members and non-members can still be observed in favour of non-members.

description: This thesis focuses on various carborane compounds and their uses for targeted cellular imaging. Cellular imaging agents have been developed for the field of medical diagnosis and treatment for some time. Many different processes have been traditionally applied in these fields, including fluorescence tagging, but these are lacking in differentiation from cellular background signals. Herein, carborane compounds have been developed for use as Raman reporters with signature absorption for BH vibrations, inside of the cell silence vibrational range. Carboranes have also been studied for the application of Boron Neutron Capture Therapy, a binary radiation therapy technique. Coupling these two ideas has lead to the formation of specific cellular targeting agents utilizing the unique BH vibrations for imaging, as well as the possible application of BNCT to the malignant tissue. This process has been developed with the aid of silver nanoparticles, which have been shown to enhance the Raman signal up to a factor of 1014 with Surface Enhanced Raman Scattering (SERS) techniques. Functionalized carborane compounds have been developed in order to study BH vibrations, and carborane-containing functionalized silver nanoparticles have been applied to target anti-EGFR antibodies for malignant tissue detection. Resulting SERS images confirmed selective tissue targeting with nanoparticle aggregate hot spots. Overlaying scanning electron microscope images with SERS BH vibrational intensity maps provided additional information on concentrations of cell surface receptors and identifying intercellular structures. Elaboration of the carborane Raman reporter resulted in two other carboranes with key functional groups, which could increase solubility, and have additional Raman handles for identification.

description: Brain death (BD) is defined as the complete and irreversible loss of brain functions. In veterinary medicine, the data regarding is scarce and further studies are needed to determine more precisely the moment of BD. In human medicine, even though data is available, there is no consensus regarding the exact point of BD among the countries. This study aims to evaluate the hematologic, biochemical and gasometric parameters in Wistar rats to help develop a better understanding regarding the brain death parameters and make them more reliable, in addition to decreasing the number of misdiagnosis early. Fifteen adult male Wistar rats (Rattus norvergicus; HanUnib:WH) were randomly distributed into three groups of five animals in each: the control group (G0) with the evaluation performed before BD; and two groups (G1 and G2) which BD was induced in different moments, the first with the evaluation immediately after the induction and one hour after induction, respectively. Samples of venous and arterial blood were collected for the complete blood count and the biochemical assay, and for the blood gas assay. The samples were collected at the appropriate time according to the group each rat belonged to. Statistically significant mean values were observed (P<0,05) for segmented, where the means of G1>G2 and G0>G2; monocytes, where G2>G1 e G0>G1; creatinine, where G2>G0; AST, where G1>G0; potassium, where G2>G0; and CHCO3, where G0>G1. In addition, it was observed that there is an individual response from each organism to brain death, which makes its precise determination even more challenging.
Common application programming interface architecture bridge for connecting heterogeneous home computing middleware

description: Microprocessors are now embedded in various equipments such as home appliances and digital audio/video devices, providing varieties of services. An integration of these services and creation of new ones is always needed to fulfill ongoing users' demands. There are a number of issues limiting the expandability of the intelligent home networks. One of these issues is that most middleware for home computing networks are not compatible with each other. To solve this problem of diversification of middleware and to ensure interoperability among them, the one-to-one bridge has been developed, which connects two specific middleware varieties and performs protocol conversion; also various one-to-any home network middleware bridges have lately been introduced. In this thesis, a proposal for any-to-any bridge connecting home computing middleware is introduced. It enables any appliance under any middleware to communicate and control any other appliances under different middleware. Also, new middleware can be easily integrated with the proposed architecture.

description: Purpose. Examine the relationship between body mass index (BMI), Waist Circumference (WC), performance in the Canadian Forces (CF) EXPRES test, and the Five Common Tasks (5CT) fitness test for CF members 50-59 years. Hypothesis. Increasing BMI and WC are related to lower performance in the EXPRES and 5CT. Results. For males (n=127, mean BMI=27.7 kg/m2(+/-3.4), mean WC=96.99 cm(+/-9.8 cm)), increasing BMI and WC correlated (p< 0.05) with poorer results on the Land Evacuation, Low High Crawl, Sandbag Carry, VO2max, Push-Ups and Sit-Ups. Performance was significantly worse for males with an "Obese" BMI than other groups and for those with a WC≥102 cm. The results for females (n=27, mean BMI=25.8 kg/m2(+/-3.6), mean WC=84.5 cm(+/-9.3 cm)) were inconclusive due to the sample size. Conclusion. For males, increasing BMI and WC were related to lower performance on some components of CF physical fitness testing. Additionally, the high percent of "Obese" individuals identifies and an alarming trend towards increased health risk.
