description: The theory that a fundamental deficit in the cortical processing of rapid, successive sensory events underlies neurodevelopmental disorders such as specific language impairment (SLI) and specific reading disability ( dyslexia) has been intensely debated for over 30 years. The present study compares behavioural performance on a range of auditory processing, reading/language, speech perception, auditory and visual temporal measures, with multichannel obligatory auditory evoked potential (AEP) responses to continuous and interleaved click train stimuli, and a /ba./-/pa./ speech continuum in normal learning children vs. children with learning disabilities ( aged 9 -17 years). In spite of strong behavioural evidence for temporal and auditory processing difficulties in the experimental group, the AEP results show a maturational lag in younger subjects but neural representation for temporal events of 19 ms duration for groups of four click trains, and 20 ms for voice-onset time gaps in a speech continuum, which is below the categorical boundary for perception of consonants. The double-on response to voice­onset time was not readily identifiable in many children. Adaptation of the auditory response was essentially normal in all children but there were subtle effects suggesting that refinements in the auditory response were still occurring. Maturational status of the brain profoundly influences the morphology of AEPs, especially in children 12 years and under. Experimental and control children did not differ significantly on many of the electrophysiological measures but younger experimental children differed from adult endpoints. Older experimental children differed frequently from adults in the N2 component. Relationships between the behavioural and electrophysiological measures were linked through maturational processes. Although rapid repetition rates are more challenging for an immature auditory system, there are subtle changes occurring into adolescence even for slower stimuli rates, paralleling the lengthy development of auditory pathway, which is contrary to the temporal processing hypothesis. The presence of a co-occurring auditory processing impairment is consistent with abnormal cortical maturation and not a temporal processing disorder of auditory cortex.
Engagement, partnership, or security? clarifying the role of community policing in Afghanistan’s counterinsurgency
Creators: name: Claybo, Daniel Bryan
Publisher: name: University of British Columbia
Year: 2011

description: Current counterinsurgency (COIN) doctrine in Afghanistan portrays community engagement and ‘winning over’ local villages as the key to COIN success. With the ongoing withdrawal of Coalition troops, strategy has increasingly emphasized the training of local security forces capable of engaging and gaining the support of Afghan communities while protecting them from the insurgent threat. This strategy draws on the principles of community policing but neither articulates them clearly nor implements them in accordance with policing experience. COIN is inherently ‘outcome-driven’ and thus is difficult to reconcile with the ‘process-oriented’ community policing approach. If community policing is to be utilized as an effective COIN engagement strategy, policing lessons must be integrated into COIN doctrine to overcome the challenges and conflicting priorities common to both efforts. I argue that three community policing lessons are particularly relevant to current COIN policy in Afghanistan. The militarization of the Afghan National Police, the ‘localizing’ of community policing arrangements, and the COIN approach to Afghan youth and children should be reconsidered in light of the experiences and research of community policing. I use a comparative case study of the COIN during the Troubles in Northern Ireland to highlight how these policies interfere with community engagement and require a clearer division of labour when pursuing COIN and community policing priorities. Community policing does not offer a solution to the challenges of community engagement during insurgency but integrating the two fields allows strategic expectations to align with the realistic limitations and possibilities of engaging communities through policing.
Tree mortality and seed survival in forest fires

Publisher: name: University of Calgary

description: This thesis combines process-based mathematical models with experimental and empirical data to examine and understand the mechanisms linking forest fire behavior to tree growth, mortality, and seed survival. The thesis begins with a review of the state of knowledge of post-fire tree mortality mechanisms at the beginning of the research. At that time, the mechanisms of phloem and vascular cambium necrosis in tree stems and branch, bud, and foliage necroses in tree crowns were well understood, but understanding of how these injuries were linked to post-fire tree growth and mortality was very limited. To explore how forest fires might affect whole-tree physiology, I examined heat effects on the hydraulic conductivity of xylem. I demonstrated for the first time that heating reduces the hydraulic conductivity of xylem via two mechanisms: enhanced cavitation and conduit wall deformation. This suggests that fire effects on whole-tree hydraulics may play an important role in post-fire tree growth and mortality. I then derive a process-based approach that links a computational fluid dynamics (CFD) model of forest fire behavior to the heat transfer mechanisms of heat injury in tree stems and crowns. These injuries are then linked to whole-tree growth and mortality using a dynamic mass balance approach. The model is currently under development and is presented here as a proof of concept. The focus then shifts to mechanisms of post-fire recruitment, and I couple a CFD fire spread model to heat transfer in closed white spruce cones to explore how non-serotinous, non-sprouting species can persist in fire regimes that theoretically should favor serotinous species. I demonstrate that non-serotinous cones can insulate seeds from heat necrosis in crown fires, but that recruitment in high numbers would require the co­incidence of a fire and a mast year. Nevertheless, post-fire recruitment from in situ aerial seedbanks can occur for non-serotinous species, and this may be an important cause of their persistence in fire regimes to which they otherwise seem poorly suited.

description: Interference alignment (IA) is a cooperative transmission strategy that, under some conditions, achieves the interference channel's maximum number of degrees of freedom. Realizing IA gains, however, is contingent upon providing transmitters with sufficiently accurate channel knowledge. In this paper, we study the performance of IA in multiple-input multiple-output systems where channel knowledge is acquired through training and analog feedback. We design the training and feedback system to maximize IA's effective sum-rate: a non-asymptotic performance metric that accounts for estimation error, training and feedback overhead, and channel selectivity. We characterize effective sum-rate with overhead in relation to various parameters such as signal-to-noise ratio, Doppler spread, and feedback channel quality. A main insight from our analysis is that, by properly designing the CSI acquisition process, IA can provide good sum-rate performance in a very wide range of fading scenarios. Another observation from our work is that such overhead-aware analysis can help solve a number of practical network design problems. To demonstrate the concept of overhead-aware network design, we consider the example problem of finding the optimal number of cooperative IA users based on signal power and mobility.

Meaning, perception, and works of art
Creators: name: Dagsson, Johannes
Publisher: name: University of Calgary
Year: 2012

description: Bibliography: p. 195-202
description: The meaning of artworks is found where conventions, intentions and perception informed by knowledge meet. In this work I present a picture of how this intersection in the conceptual landscape is best understood. I begin by offering an account of conventions that draws on Ruth Millikan's model of leader-follower conventions. I then give an account of intentions and intentional actions where the connection between intentions and intentional actions is 'loose' enough so that we can talk about artworks as being intentionally made, without having to say that a particular feature of artworks is intentional by virtue of having been intended by the author of the work. In order to explain the role of perception in how agents attribute meaning to artworks, I rely on Michael Polanyi's account of tacit knowledge, and Alva Noe's theory of perception as active engagement with the world. An agent's perception of artworks is informed by knowledge. Most of that knowledge is tacit. In both making and experiencing works of art, agents make use of perception informed by tacit knowledge and knowledge of sensorimotor laws that hold between the content of our experience and the external world. The way we attribute meaning to artworks is conditioned by this kind of perception and knowledge. This model of perception can also explain how we are aware of conventions when making or appreciating works of art. Instead of addressing the question 'what is a work of art?' this thesis addresses the question, 'how do we attribute meaning to works of art?' The answer is that we do so by being the knowledgeable perceivers we are, and by being able to have the kind of experience to which interpretable objects give rise.
Entaglement sharing protocol via quantum error correcting code
Creators: name: Choi, Ran Hee
Publisher: name: University of Calgary
Year: 2012

description: Bibliography: p. 74-79
description: Quantum secret sharing concerns secure and reliable distribution of classical or quantum information by a dealer to a set of "players" such that authorized subsets of players can access full information and unauthorized subsets are denied any information what­soever. Exploiting quantum secret sharing concepts and techniques, I introduce a new protocol of "entanglement sharing" wherein half of maximally entangled bipartite states arc encrypted into multipartitc states in such a way that unauthorized players can only establish shared separable (not entangled) states with the dealer. Only authorized sub­sets of players obtain entangled states, which enable quantum information tasks such as quantum teleportation. Entanglement sharing can reduce the size of shares to individual players by half depending on the choice of encoding operation, as I show with the [[4, 2, 2]] stabilizer code. In fact, the [[4, 2, 2]] stabilizer code induces an optimal and threshold entanglement sharing scheme. Furthermore, I propose a new secrecy condition of quantum ramp secret sharing based on the bipartite setting of entanglement sharing. Ramp secret sharing relieves the band­width requirement of a protocol by reducing the size of shares at a cost of information leakage. Although quantum ramp secret sharing has been studied, to date it has been a challenge to classify leaked information. In this thesis, I define classical and quantum information with respect to the channels through which information is transmitted, and determine whether the information leakage is classical or quantum. Finally, I establish hybrid entanglement sharing by introducing classical shares in non-perfect entanglement sharing schemes. Hybrid entanglement sharing exploits a tech­nique of locking entanglement with classical information, and can be devised from any quantum error correcting code.

description: Presented at the 8th international congress for wildlife and livelihoods on private and communal lands: livestock, tourism, and spirit, that was held on September 7-12, 2014 in Estes Park, Colorado.
description: South Africa is unique in having created an extensive game ranching industry across a wide range of indigenous ungulates to pachyderms and even large predators. From small beginnings by a handful of private landowners and forward thinking conservationists this industry now encompasses approximately 17% of the countries land surface area and herds may number as many as 20 million ungulates. The industry has an annual turnover exceeding a billion USD and is a significant contributor to the burgeoning green economy that includes ecotourism, hunting and many allied industries such as fencing, infrastructure and equipment as well as a host of consultants and practitioners from veterinarians, translocators, ecologists and other professionals. The industry has contributed significantly to the conservation of a number of species such as white rhino, black wildebeest, sable and roan antelope and a number of meta-populations are now biased towards private land more than in official protected areas. The industry has now reached a crossroads in terms of its divergence into more specialized intensive breeding of species for specific traits such as trophy size and colour variation and a departure in many instances from the official conservation objectives of the country. This paper will discuss the current status and position of the industry in relation to the official conservation stance and unbundle the contributory factors to the threatening conflict between the conservation fraternity and game ranching industry. The paper will further propose potential ways forward in dealing with this unique state of affairs in South Africa considering that communal lands and many commercial farmers consider wildlife a viable option for the future.

A growing disconnect: can the contemporary terrorism literature explain domestic homegrown terrorism?
Creators: name: Zekulin, Michael G.
Publisher: name: University of Calgary
Year: 2012

description: Bibliography: p. 272-299
description: The past several years have seen an increase in the number of Islamic inspired terrorist attacks targeting western democratic states. However, the individuals planning and conducting these attacks are not representatives or members of foreign terrorist groups. Instead, those perpetrating these attacks are citizens or long standing residents of those states and thus these attacks can be considered to be "domestic homegrown" terrorism. This dissertation examines this phenomenon and makes several observations. First, an indepth examination of the modem and contemporary terrorism literature and case study analysis reveals that domestic homegrown terrorism challenges our understanding and conceptualization of terrorism since these recent attacks cannot be explained by the lliterature. Domestic homegrown terrorist attacks demonstrate key differences among four elements emphasized in the literature: role of leadership, role of the organization, socialization and the group dynamic. Second, this dissertation creates a definition of domestic homegrown terrorism which can serve as a basis for further discussion and analysis. Third, it identifies why the distinction and definition of domestic homegrown terrorism is important for those in the field of terrorism studies as well as government officials and policymakers. Domestic homegrown terrorism represents a growing threat and this dissertation provides a framework for future discussions on how it is different from terrorism previously seen and some of the challenges its unique form may pose.

description: Using density functional theory (DFT) we report results for the electronic structure and vibrational dynamics of hydrogenated β reconstructed Silicon Carbide (001) (3x2) surfaces with various levels of hydrogenation. These results were obtained using density functional theory with a generalized gradient exchange correlation function. The calculations reveal that metallization can be achieved via hydrogen atoms occupying the second silicon layer. Further increases of hydrogen occupation on the second silicon layer sites result in a loss of this metallization. For the former scenario, where metallization occurs, we found a new vibrational mode at 1870 cm-1, which is distinct from the mode associated with hydrogen atoms on the first layer. Furthermore, we found the diffusion barrier for a hydrogen atom to move from the second to the third silicon layer to be 258 meV.

description: Diagnosis and monitoring of kidney transplant allografts is supported by microscopic analysis of renal biopsy samples. Visual analysis by pathologists allows for incon­sistencies, bias, and inaccuracies; image analysis via digital processing can address these concerns, reduce effort, and potentially provide a second opinion. In this thesis, digital image analysis methods for automatic segmentation of structures in images of renal biopsy samples are presented. 1\/Iethods for accurate segmentation of the effective biopsy area include opening by reconstruction, morphological closing, and erosion. The re ults were compared to contours drawn by an experienced pathologist; the mean distance to the closest point was 5.46 ± 3.92 µm (6 ± 4.31 pixels) and the true-positive fraction was 98.25 ± 1.77%. Methods for automatic segmentation of cell nuclei are also presented, including, automatic thresholding, adaptive threshold­ing, and morphological granulometry. The results were verified against pathologist annotations; true-positive ratios were in the range of 0.80 to 0.93.

description: For improving the sustainability and resilience of EU farming systems, it is important to assess their likely responses to future challenges under future scenarios. We evaluated future resilience in 11 case studies across the EU, using a soft coupling of different qualitative and quantitative approaches. The qualitative approach was FoPIA-SUREFarm 2, a participatory approach in which stakeholders identified critical thresholds for current systems, evaluated expected system performance when these thresholds would be exceeded, envisaged alternative future states of the systems (and their impact on indicators and resilience attributes), as well as strategies to get there. Quantitative approaches included models simulating the behavior of the systems under some specific challenges and scenarios. The models differed in assumptions and aspects of the farming systems described: Ecosystem Service modelling focused on the biophysical level (considering land cover and nitrogen fluxes), AgriPoliS considered, with an agent-based approach, socio-economic processes and interactions within the farming system, and System Dynamics, taking a holistic approach, explored some of the feedback loops mechanisms influencing the systems resilience from both a qualitative and quantitative approach. The report showed complementarity between different methods and, above all, between quantitative and qualitative approaches. Qualitative approaches are needed for interaction with stakeholders, understand perceptions of stakeholders, consider available knowledge on all aspects of the farming system, including social dimensions, and perform a good basis for developing and parameterizing quantitative models. Quantitative methods allow quantifying the consequences of mental models, operationalizing the impact of stresses and strategies to tackle them and help to unveil unintended consequences, but are limited in their reach. Both are needed to assess resilience of farming systems and suggest strategies for improvement and to help stakeholders to wider their views regarding potential challenges and ways to tackle them.

Stories of hope: conversations with aboriginal women who have experienced incarceration
Creators: name: Radtke, Janis Leigh
Publisher: name: Nursing
Year: 2012

description: Bibliography: p. 114-125
description: The purpose of this research study was to explore the meaning of hope for Aboriginal women who have experienced incarceration and to offer an opportunity for their voices to emerge. Conversations with six Aboriginal women provided descriptions of how hope influenced their lives before, during, and after incarceration. van Manen's (1990) phenomenological research design guided this study together with a feminist perspective. The colonization and assimilation of First Nations people by Canada's early settlers changed the fabric of their lives and created an inherent burden that is distressingly evident to this day. Aboriginal women, once respected and valued, struggle daily to meet the demands of a society that has oppressed them for decades. Yet, somehow, these brave women have found the strength, resilience, and survival skills to meet another day. This thesis presents their stories and discusses the underlying themes as well as the implications for nursing and future research.

description: The purpose of this paper is to determine the determinants of trophy (international) hunters spending in South Africa. Hunters in South Africa can be divided into two categories namely biltong (primarily local hunters) and trophy (primarily foreign hunters) and hunting makes a significant contribution to the tourism industry and the economy in general. One of the key contributors or ingredients of economic impact studies is tourists (hunters) spending, and the 9000 international hunters spend approximately R1.2 billion in 2013 which can still be increased. The reason being that hunting lodges and game farmers are mostly located in rural provinces with high rates of unemployment. Therefore this research can help practitioners and marketers alike to focus their marketing and development activities and resources on these variables. The research was conducted by means of a structured web based questionnaire survey and this is the first time that the determinants have been identified in South Africa which has a vibrant hunting industry.

description: This thesis focuses on computer-related and lighting energy consumption in post-secondary educational institutions. In this respect, artificial intelligence and data association mining are proposed as tools to identify and reduce energy waste. First, an artificial intelligence­based method for forecasting computer usage is proposed. Based on the models' forecast, workstations can be turned on and off, in order to strike a balance between energy sav­ings and user comfort. The models are evaluated on different datasets and their results compared to commercially available alternatives. Second, a data association mining-based approach is proposed to uncover possible re­lationships between occupancy patterns and lighting-related energy waste in classrooms. A wireless data collection system is used to log data from both lighting consumption and occupancy states during a year. Next, energy savings results of using the proposed approach are compared to those of an occupancy-activated lighting control system for classrooms.

For weak enough magnetic fields, leptonic models can reproduce the few seconds delay of the onset of GeV photon emission observed by Fermi-LAT, due to the slow growth of the target photon field for inverse Compton scattering. However, even for stronger magnetic fields, the GeV delay can be explained with hadronic models, due to the long acceleration timescale of protons and the continuous photopion production after the end of the particle injection. While the FWHMs of the MeV and GeV lightcurves are almost the same in one-zone leptonic models, the FWHM of the 1--30 GeV lightcurves in hadronic models are significantly wider than those of the 0.1--1 MeV lightcurves. The amount of the GeV delay depends on the importance of the Klein--Nishina effect in both the leptonic and hadronic models. In our examples of hadronic models the energies of the escaped neutrons are comparable to the gamma-ray energy, although their contribution to the ultra high-energy cosmic rays is still subdominant. The resulting neutrino spectra are hard enough to avoid the flux limit constraint from IceCube. The delay of the neutrino emission onset is up to several times longer than the corresponding delay of the GeV photon emission onset. The quantitative differences in the lightcurves for various models may be further tested with future atmospheric Cherenkov telescopes whose effective area is larger than that of Fermi-LAT, such as CTA.

description: Thermoelectric effects in magnetic nanostructures and the so-called spin caloritronics are attracting much interest. Indeed it provides a new way to control and manipulate spin currents which are key elements of spin-based electronics. Here we report on giant magnetothermoelectric effect in Al2O3 magnetic tunnel junctions. The thermovoltage in this geometry can reach 1 mV. Moreover a magneto-thermovoltage effect could be measured with ratio similar to the tunnel magnetoresistance ratio. The Seebeck coefficient can then be tuned by changing the relative magnetization orientation of the two magnetic layers in the tunnel junction. Therefore our experiments extend the range of spintronic devices application to thermoelectricity and provide a crucial piece of information for understanding the physics of thermal spin transport.

The Paradox of the Virgin-Theotokos: Evangelism and Imperial Politics in the 5th Century Byzantine World
Creators: name: McGuckin, John A.
Publisher: name: Columbia University
Year: 2001
Subjects: Religion
Theology

description: This article considers the theological and political aspects involved in the 5th C controversy over the title 'Mother of God' as exemplified in the conflict between Nestorius of Constantinople and Cyril of Alexandria. The aristocratic women of the Byzantine capital, as well as popular religious movements in Egypt and Asia Minor, helped the title achieve ecumenical ascendancy in early Christianity.

description: Family presence during resuscitation (FPDR) is a practice that is increasing in critical care units. In this philosophical hermeneutic study, four individuals who experienced resuscitation were interviewed to gain an understanding of the experience of FPDR for the patients. Findings revealed that family presence for individuals who experienced resuscitation provided an ongoing understanding of the experience. Family presence also provided a connection to the family and a reason to survive the resuscitation. In addition the participants described an ability to see or know what was happening even in a state of coma and/or sedation. As well, the definitions of "family," "presence," and "resuscitation" were explored with the participants and it was found that, while definitions had little meaning for the participants, their individual experiences were significant. These findings provided an understanding of the patients' experiences of FPDR and this study suggests that FPDR can continue to evolve and be integrated into practice.
Control and design of a remote small hybrid power system

description: If a wind and solar hybrid electrical power system is designed for a remote location, data on wind and solar resources is often quite limited. If available, monthly average data is most often used. However, it is suggested here that higher resolution resource data, such as hourly average data, can have a significant effect on system component sizing. In particular, the anti-correlation of wind and solar availability and also the effects of deferrable loads are studied in simulation using Hybrid2 for a 10 kW wind-solar system with diesel back up. It is shown that diesel fuel use is reduced by 80% compared to the diesel-only based system, and it is also shown that the use of hourly average data results in fewer short-cycling operations of the diesel source and reduced spillage of power as compared to the system designed with monthly average data.
Pink slips for politicians: assessing recall in Canada
Creators: name: McDonald, Meredith
Publisher: name: University of Calgary
Year: 2012

description: Bibliography: p. 130-133
description: Recall, the third, lesser-known member of the direct democracy triumvirate after the initiative and referendum, is a device that allows constituents to remove and replace an elected official before the next general election. Used almost exclusively in the United States, recall has nonetheless left a faint footprint on Canada's political landscape. From its introduction in Depression-era Alberta, to its sainted position among the tenets of the Reform Party's democratic reform agenda, to the spate ofrecent efforts to recall MLAs in British Columbia who supported the unpopular HST, there is a pool of Canadian experience, albeit shallow, through which to wade and on which to reflect. What are the implications of transferring a device developed in the American system that permits representatives significant latitude to act independently to the Canadian parliamentary system that allows for far less autonomy?
Three particle superstring amplitudes with massive legs

Subjects: subject: High Energy Physics - Theory (hep-th)

description: On-shell superspaces and associated spinor helicity techniques give an efficient formulation of the Ward identities of on-shell supersymmetry for scattering amplitudes and supply tools to construct their solutions. Based on these techniques in this paper the general solutions of the Ward identities are presented for three particle scattering amplitudes with one, two or three massive legs for simple supersymmetry in ten and eight dimensions. It is shown in examples how these solutions may be used to obtain concrete amplitudes for the closed (IIB) and open superstring in a flat background. Explicit results include all three point amplitudes with one massive leg whose functional form is shown to be dictated completely by super-Poincare symmetry. The resulting surprisingly simple series only involves massive superfields labelled by completely symmetric little group representations. The extension to more general explicit three and higher point amplitudes in string theory is initiated. In appendices the field content of the fundamental massive superfields of the open and closed superstring are listed in terms of the Dynkin labels of a variety of groups which may be of independent interest.

Reconquering “Sepharad”: Hispanism and Proto-Fascism in Giménez Caballero's Sephardist Crusade
Creators: name: Friedman, Michal
Publisher: name: Columbia University
Year: 2011
Subjects: History

description: this article examines Ernesto Giménez Caballero’s interest in the Sephardim through a close study of the Gaceta Literaria, government reports documenting his voyages to the Sephardic world, and documentary film. Until recently, Giménez Caballero’s importance in Spanish intellectual history has been trivialized by his caricaturization as a sensationalist ideologue. As Enrique Selva has recently argued, perhaps more than any other Spanish intellectual of his time, Giménez Caballero fully immersed himself in the divergent intellectual tides of the interwar period, by placing himself ‘‘en el centro del huracán’’ [in the eye of the hurricane]. Moreover, it was precisely this posturing*which some scholars have dismissed as extravagant and histrionic* that allowed Giménez Caballero to play a seminal role in articulating and assimilating Fascist doctrine in the Spanish context, even to the point of becoming, in Selva’s words, ‘‘la mayor incarnación de la vía a través de la cual se formula la ideología fascista y se comienza a difundir en nuestro país’’ [the greatest incarnation of the particular path through which Fascist ideology was formulated and began to be disseminated in Spain]. As Douglas Foard argues, Giménez Caballero’s trajectory was not anomalous or eccentric, but rather representative of the volatile political and intellectual climate throughout Western Europe in the interwar period.
