title: Measuring Systemic Risk Across Financial Market Infrastructures
Creators: name: Li, Fuchun

Publisher: name: Bank of Canada
Year: 2016

description: We measure systemic risk in the network of financial market infrastructures (FMIs) as the probability that two or more FMIs have a large credit risk exposure to the same FMI participant. We construct indicators of credit risk exposures in three main Canadian FMIs during the period 2007–11 and use extreme value methods to estimate this probability. We find large differences in the contribution to systemic risk across participants. We also find that when participants are in financial distress, they tend to create large credit exposures in two or more FMIs. Our results suggest that an appropriate oversight of FMIs may benefit from an in-depth system-wide analysis, which may have useful implications for the macroprudential regulation of the financial system.
description: Nous mesurons le risque systémique dans le réseau des infrastructures de marchés financiers (IMF) en fonction de la probabilité que deux IMF ou plus aient une forte exposition au risque de crédit à l’égard d’un même participant. Pour ce faire, nous construisons des indicateurs des expositions au risque de crédit présentes dans trois grandes IMF canadiennes pour la période de 2007 à 2011, et avons recours à des méthodes fondées sur la théorie des valeurs extrêmes pour estimer cette probabilité. Les participants ne sont pas une source de risque systémique au même degré : de ce point de vue, nous observons d’importantes différences entre eux. Nous constatons également que lorsqu’ils connaissent des difficultés financières, les participants ont tendance à accroître l’exposition au risque de crédit dans deux IMF ou plus. Nos résultats indiquent qu’il serait bon, pour une surveillance appropriée des IMF, d’effectuer une analyse approfondie de l’ensemble du réseau, analyse qui pourrait avoir son utilité pour la réglementation macroprudentielle du système financier.

Linked Pipes

description: Abstract At Linked Pasts IV in Mainz 2018, the Linked Pasts Network had a session on "Linked Data Tools and Pipelines". As a result, the LinkedPipes Working Group was born, further developed during Linked Pasts V in Bordeaux. The main goal of Linked Pipes is to semantically model pipelines for LOD related workflows. The Linked Pipes is based on a specific ontology which assumes that a tool is linked into the Linked Open Data Cloud via Wikidata. This hackathon will be a virtual discussion room for further development of the data structure and goal, and discussion of ways to participate. It is splitted into two online sessions where the community may get an introduction, try out modelling linked pipes, report challenges and problems, discuss solutions and plan the next steps. A particular emphasis should be given to the incorporation and reuse of related Linked Data vocabularies for software workflow descriptions, a connection of linked pipes to traditional modes of publication (publication workflow identifiers) and the description of provenance of data and an adequate representation of such pipes to all audiences. The results should be implemented, sketched, discussed and finally published as a working paper for documenting data workflows.

description: The Event Horizon Telescope, a global submillimeter wavelength very long baseline interferometry array, produced the first image of supermassive black hole M87* showing a ring of diameter $θ_d= 42\pm 3\,μ$as, inferred a black hole mass of $M=(6.5 \pm 0.7) \times 10^9 M_\odot $ and allowed us to investigate the nature of strong-field gravity. The observed image is consistent with the shadow of a Kerr black hole, which according to the Kerr hypothesis describes the background spacetimes of all astrophysical black holes. The hypothesis, a strong-field prediction of general relativity, may be violated in the modified theories of gravity that admit non-Kerr black holes. Here, we use the black hole shadow to investigate the constraints when rotating regular black holes (non-Kerr) can be considered as astrophysical black hole candidates, paying attention to three leading regular black hole models with additional parameters $g$ related to nonlinear electrodynamics charge. Our interesting results based on the systematic bias analysis are that rotating regular black holes shadows may or may not capture Kerr black hole shadows, depending on the values of the parameter $g$. Indeed, the shadows of Bardeen black holes ($g\lesssim 0.26 M$), Hayward black holes ($g\lesssim 0.65 M$), and non-singular black holes ($g\lesssim 0.25 M$) are indistinguishable from Kerr black hole shadows within the current observational uncertainties, and thereby they can be strong viable candidates for the astrophysical black holes. Whereas Bardeen black holes ( $g\leq 0.30182M$), Hayward black holes ($g\leq 0.73627M$), and non-singular black holes ($g\leq 0.30461M$), within the $1σ$ region for $θ_d= 39\, μ$as, are consistent with the observed angular diameter of M87*.

description: We analyse the decay $Θ_s(1/2^+)\to NK$ in a non-relativistic Fock space description using three and five constituent quarks for the nucleon and the pentaquark, respectively. Following Jaffe and Wilczek \cite{jw}, we assume that quark-quark correlations in spin-zero state play an important role for the pentaquark internal structure. Within this scenario, a strong dynamical suppression of the decay width is shown to be possible only if the pentaquark has an asymmetric "peanut" structure with the strange antiquark in the center and the two extended composite diquarks rotating around. In this case a decay width of $\simeq$ 1 MeV may be a natural possibility.

description: In this paper the impact of changes in wool promotion expenditure and changes in expenditure on the promotion of competing fibres are examined using an equilibrium displacement model. The emphasis is on examining impacts on producer profits net of promotion expenditure and on benefit-cost ratios measuring changes in producer surplus relative to changes in promotion expenditure. It was found, for example, that incremental expenditure on apparel wool promotion on the domestic market is unprofitable but incremental expenditure on promotion of apparel wool on the export market is generally profitable. Further, it was found that increased promotion of cotton and man-made fibres on the export market, with promotion of apparel wool unchanged, would reduce profits to apparel wool producers. Finally, a case is made for improved data availability in order to allow more comprehensive ex-ante and ex-post evaluations of promotion programs, thereby increasing the intensity of scrutiny of promotion programs to a level more in line with that for investment in rural research and development.

description: The European Gaia astrometry mission is due for launch in 2011. Gaia will rely on the proven principles of ESA's Hipparcos mission to create an all-sky survey of about one billion stars throughout our Galaxy and beyond, by observing all objects down to 20th magnitude. Through its massive measurement of stellar distances, motions and multi-colour photometry it will provide fundamental data necessary for unravelling the structure, formation and evolution of the Galaxy. This paper presents the design and performance of the broad- and medium-band set of photometric filters adopted as the baseline for Gaia. The nineteen selected passbands (extending from the ultraviolet to the far-red), the criteria, and the methodology on which this choice has been based are discussed in detail. We analyse the photometric capabilities for characterizing the luminosity, temperature, gravity and chemical composition of stars. We also discuss the automatic determination of these physical parameters for the large number of observations involved, for objects located throughout the entire Hertzsprung-Russell diagram. Finally, the capability of the photometric system to deal with the main Gaia science case is outlined.

description: In the framework of the nonlinear $Λ$-model we investigate propagation of solitons in atomic vapors and Bose-Einstein condensates. We show how the complicated nonlinear interplay between fast solitons and slow-light solitons in the $Λ$-type media points to the possibility to create optical gates and, thus, to control the optical transparency of the $Λ$-type media. We provide an exact analytic description of decelerating, stopping and re-accelerating of slow-light solitons in atomic media in the nonadiabatic regime. Dynamical control over slow-light solitons is realized via a controlling field generated by an auxiliary laser. For a rather general time dependence of the field; we find the dynamics of the slow-light soliton inside the medium. We provide an analytical description for the nonlinear dependence of the velocity of the signal on the controlling field. If the background field is turned off at some moment of time, the signal stops. We find the location and shape of the spatially localized memory bit imprinted into the medium. We discuss physically interesting features of our solution, which are in a good agreement with recent experiments.

description: A variety of terrestrial planets with different physical parameters and exotic atmospheres might plausibly exist outside our Solar System, waiting to be detected by the next generation of space-exploration missions. Some of these planets might transit their parent star. We present here the first study of atmospheric signatures of transiting Earth-size exoplanets. We focus on a limited number of significant examples, for which we discuss the detectability of some of the possible molecules present in their atmospheres, such as water, carbon dioxide, ozone or molecular oxygen. To this purpose, we developed a model to simulate transmission spectra of Earth-size exoplanets from the ultraviolet to the near infrared. According to our calculations, the signatures of planetary atmospheres represent an absorption of a few parts-per-million (ppm) in the stellar flux. The atmospheres of a few Earth-like planets can be detected with a 30-40m telescope. The detection of the extensive atmospheres of tens of small satellites of giant exoplanets and hundreds of hypothetical ocean-planets can be achieved with 20-30m and 10-20m instruments, respectively, provided all these planets are frequent and they are efficiently surveyed. We also found that planets around K stars are favored, mainly because these stars are more numerous and they are smaller compared to G or F stars. While not addressed in this study, limitations might come from the stellar photometric micro-variability.

Ultraviolet Dust Grain Properties in Starburst Galaxies: Evidence from Radiative Transfer Modeling and Local Group Extinction Curves
Creators: name: Gordon, Karl D.
Publisher: name: arXiv
Year: 2005
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: This paper summarizes the evidence of the ultraviolet properties of dust grains found in starburst galaxies. Observations of starburst galaxies clearly show that the 2175 A feature is weak or absent. This can be the result of radiative transfer effects (mixing the dust and stars) or due to dust grains which do not have this feature. Spherical DIRTY radiative transfer models imply that it is not radiative transfer effects, but other radiative transfer models with disk/bulge geometries have found cases where it could be radiative transfer effects. Recent work on the extinction curves in the Magellanic Clouds and Milky Way has revealed that the traditional explanation of low metallicity for the absence of the 2175 A feature in the Small Magellanic Cloud is likely incorrect. The SMC has one sightline with a 2175 A feature and the Milky Way has sightlines without this feature. In addition, where the 2175 A feature is found to be weak or absent in both Magellanic Clouds and the Milky Way, there is evidence for recent star formation. Taking the sum of the radiative transfer modeling of starburst galaxies and the behavior of Local Group extinction curves, it is likely that the dust grains in starburst galaxies intrinsically lack the 2175 A feature.

description: This paper demonstrates that, in situations in which a cumulative externality exists, the basic nature and extent of resource misallocation may be substantially less than we imagine. This conclusion stems from deriving consistent conjectures in a unified framework in which congestion is present. Experiments support the conclusion that, when numbers of agents are small, when there is little heterogeneity among them, and when they have the opportunity to observe each other during repeated experiment, the market allocation may be efficient.

description: Mining a set of meaningful topics organized into a hierarchy is intuitively appealing since topic correlations are ubiquitous in massive text corpora. To account for potential hierarchical topic structures, hierarchical topic models generalize flat topic models by incorporating latent topic hierarchies into their generative modeling process. However, due to their purely unsupervised nature, the learned topic hierarchy often deviates from users' particular needs or interests. To guide the hierarchical topic discovery process with minimal user supervision, we propose a new task, Hierarchical Topic Mining, which takes a category tree described by category names only, and aims to mine a set of representative terms for each category from a text corpus to help a user comprehend his/her interested topics. We develop a novel joint tree and text embedding method along with a principled optimization procedure that allows simultaneous modeling of the category tree structure and the corpus generative process in the spherical space for effective category-representative term discovery. Our comprehensive experiments show that our model, named JoSH, mines a high-quality set of hierarchical topics with high efficiency and benefits weakly-supervised hierarchical text classification tasks.

description: The assumptions which must be made to accept ratios of energy output to energy input as an efficiency measure with normative significance are examined and found to be unrealistic. It is considered better for governments to modify market prices where divergences exist between private and social costs or benefits than to use energy ratios, or prices determined by energy considerations, as a criterion in allocating resources. Moreover, in a trading world, energy considerations are often of little use in positive analysis of the relationship between energy prices and the prices, or profitability of production, of different foods in a particular country.

description: We consider a pairing producing various cyclic Hochschild cocycles, which led Alain Connes to cyclic cohomology. We are interested in geometrical meaning and homological properties of this pairing. We define a non-trivial pairing between the homology of a Lie-Rinehart (super-)algebra with coefficients in some partial traces and relative periodic cyclic homology. This pairing generalizes the index formula for summable Fredholm modules, the Connes-Kubo formula for the Hall conductivity and the formula computing the K0-group of a smooth noncommutative torus. It also produces new homological invariants of proper maps contracting each orbit contained in a closed invariant subset in a manifold acted on smoothly by a connected Lie group. Finally we compare it with the characteristic map for the Hopf-cyclic cohomology.

Industrial ecology and the capacity for implementing eco-industrial parks in Richmond, British Columbia
Creators: name: Henney, Karly Danielle
Publisher: name: University of British Columbia
Year: 2009

description: Humans are at a critical juncture in terms of how to evolve to deal with increasingly urgent global ecological and social trends. Questions of ecological sustainability are inextricably linked to patterns of human production and consumption. The current economic system operates without regard for unbending ecological laws. Industrial Ecology is an alternative theory for planning, designing and managing production and consumption activities to operate within biophysical limits by applying ecological principles to industrial operations. This thesis explores implementing Industrial Ecology with eco-industrial parks - sites with a redundant and diverse set of businesses co-located to operate as ecologically compatible and economically viable systems. Projects underway are using different concepts, strategies and organizational forms, but all seek to apply Industrial Ecology principles. My literature review discusses the benefits, challenges and risks associated with eco-industrial parks and summarizes key design elements from existing cases. The City of Richmond is used to analyze the capacity of a municipality and its policy and regulatory framework for eco-industrial parks based on key design elements. Structured interviews informed the evaluation of capacity. I found Richmond's Official Community Plan, Industrial Strategy and zoning bylaw conceptually support and would not prevent eco-industrial park development; however, policy lacks economy-environment linkages and does not further Industrial Ecology. Regulatory barriers to implementation of physical design features of eco-industrial parks involve zoning, land use patterns, permitting, ownership and water concerns, but the barriers are flexible in terms of presenting obstacles rather than being prohibitive. Municipal capacity gaps exist for non-physical design features relating to information systems and organization and management. I make recommendations for Richmond to increase eco-industrial development capacity based on Industrial Ecology theory, other eco-industrial park cases and a personal interpretation of what is required for sustainable development. Richmond has significant potential to become a leader in industrial innovation at the level of local systems to which horizontal and vertical links can be established for achieving long-term sustainability.

description: There has been a low level of methodological controversy within the Australian agricultural economics profession. Johnson's 1963 paper is the most significant and in it he passed criticisms on agricultural production economists not unlike those currently being made by political economists of economics in general. These past criticisms have in the main been ignored by the Australian profession but it is suggested that they are now being pushed with renewed vigour and they can no longer be ignored. It is argued that our policy work has by and large been successful and effective except for significant areas where our methodology was of restricted usefulness. In farm management the Johnsonian strictures would seem to apply but a more charitable interpretation is provided which should meet the approval of the political economists. Our almost complete neglect of development economics must soon draw to an end and we will find that the methodologies which we have relied on heavily and fairly successfully must be augmented as we become more involved in this field. The political economics challenge should be recognized and accepted with relish because the nature of our work is changing and will continue to change in the future. We have adapted fairly well as adjustment and equity have become major policy concerns. Meeting the political economics challenge will help this process of adaptation.
title: Manual of the Matlab Script FAST Calibration v2.0
Creators: name: Ziegler, Moritz
Publisher: name: GFZ German Research Centre for Geosciences
Year: 2021

description: The 3D geomechanical-numerical modelling aims at a continuous description of the stress state in a subsurface volume. The model is fitted to the model-independent stress data records by adaptation of the displacement boundary conditions. This process is herein referred to as model calibration. Depending on the amount of available stress data records and the complexity of the model the calibration can be a lengthy process of trial-and-error to estimate the best-fit boundary conditions. The tool FAST Calibration (Fast Automatic Stress Tensor Calibration) is a Matlab script that facilitates and speeds up this calibration process. By using a linear regression it requires only three test model scenarios with different displacement boundary conditions to calibrate a geomechanical-numerical model on available stress data records. The differences between the modelled and observed stresses are used for the linear regression that allows to compute the displacement boundary conditions required for the best-fit estimation. The influence of observed stress data records on the best-fit displacement boundary conditions can be weighted. Furthermore, FAST Calibration provides a cross checking of the best-fit estimate against indirect stress information that cannot be used for the calibration process, such as the observation of borehole breakouts or drilling induced fractures. The script files are provided for download at http://github.com/MorZieg/FAST_Calibration. Tab. 0-1 gives an overview of the folder structure and input files with a short explanation.

description: We present a new method based on functional tensor decomposition and dynamic tensor approximation to compute the solution of a high-dimensional time-dependent nonlinear partial differential equation (PDE). The idea of dynamic approximation is to project the time derivative of the PDE solution onto the tangent space of a low-rank functional tensor manifold at each time. Such a projection can be computed by minimizing a convex energy functional over the tangent space. This minimization problem yields the unique optimal velocity vector that allows us to integrate the PDE forward in time on a tensor manifold of constant rank. In the case of initial/boundary value problems defined in real separable Hilbert spaces, this procedure yields evolution equations for the tensor modes in the form of a coupled system of one-dimensional time-dependent PDEs. We apply the dynamic tensor approximation to a four-dimensional Fokker-Planck equation with non-constant drift and diffusion coefficients, and demonstrate its accuracy in predicting relaxation to statistical equilibrium.

description: It is shown that the band structure of single-wall semiconducting carbon nanotubes (CNT) is analogous to relativistic description of electrons in vacuum, with the maximum velocity $u$= $10^8$cm/s replacing the light velocity. One-dimensional semirelativistic kinematics and dynamics of electrons in CNT is formulated. Two-band k.p Hamiltonian is employed to demonstrate that electrons in CNT experience a Zitterbewegung (trembling motion) in absence of external fields. This Zitterbewegung should be observable much more easily in CNT than its analogue for free relativistic electrons in vacuum.

description: Aiming to extend the census of RR Lyrae stars to highly reddened low-latitude regions of the central Milky Way, we performed a deep near-IR variability search using data from the VISTA Variables in the Vía Láctea (VVV) survey of the bulge, analyzing the photometric time series of over a hundred million point sources. In order to separate fundamental-mode RR Lyrae (RRab) stars from other periodically variable sources, we trained a deep bidirectional long short-term memory recurrent neural network (RNN) classifier using VVV survey data and catalogs of RRab stars discovered and classified by optical surveys. Our classifier attained a ~99% precision and recall for light curves with signal-to-noise ratio above 60, and is comparable to the best-performing classifiers trained on accurate optical data. Using our RNN classifier, we identified over 4300 hitherto unknown bona fide RRab stars toward the inner bulge. We provide their photometric catalog and VVV J,H,Ks photometric time-series.

description: The problem of Rabi oscillations in a qubit coupled to a fluctuator and in contact with a heath bath is considered. A scheme is developed for taking into account both phase and energy relaxation in a phenomenological way, while taking full account of the quantum dynamics of the four-level system subject to a driving AC field. Significant suppression of the Rabi oscillations is found when the qubit and fluctuator are close to resonance. The effect of the fluctuator state on the read-out signal is discussed. This effect is shown to modify the observed signal significantly. This may be relevant to recent experiments by Simmonds et al. [Phys. Rev. Lett. 93, 077003 (2004)].

description: La prospective envisage les futurs possibles. Pour les systèmes alimentaires 2 scénarios, affichant un objectif désormais commun de neutralité carbone, font l’objet de controverses. L’un, tendanciel, prône l’intensification chimique et biotechnologique, l’autre l’intensification écologique. Pour dépasser les influences conflictuelles introduisant des biais de connaissance et de préconisation politique, une contextualisation structurelle, spatiale et temporelle s’avère nécessaire. La 5e transition alimentaire en cours devrait favoriser le scénario socio-écologique
description: Foresight considers possible futures. For food systems 2 scenarios, displaying a now-common objective of carbon neutrality, are the subject of controversy. One, advocates chemical and biotechnological intensification, the other ecological intensification. To overcome the conflicting influences introducing knowledge and political recommendation biases, a structural, spatial and temporal contextualization is necessary. The 5th current food transition should favor the socio-ecological scenario

description: In order to produce a low energy effective field theory from a string model, it is necessary to specify a vacuum state. In order that this vacuum be supersymmetric, it is well known that all field expectation values must be along so-called flat directions, leaving the F- and D-terms of the scalar potential to be zero. The situation becomes particularly interesting when one attempts to realize such directions while assigning VEVS to fields transforming under non-Abelian representations of the gauge group. Since the expectation value is now shared among multiple components of a field, satisfaction of flatness becomes an inherently geometrical problem in the group space. Furthermore, the possibility emerges that a single seemingly dangerous F-term might experience a self-cancellation among its components. The hope exists that the geometric language can provide an intuitive and immediate recognition of when the D and F conditions are simultaneously compatible, as well as a powerful tool for their comprehensive classification. This is the avenue explored in this paper, and applied to the cases of SU(2) and SO(2N), relevant respectively to previous attempts at reproducing the MSSM and the flipped SU(5) GUT. Geometrical interpretation of non-Abelian flat directions finds application to M-theory through the recent conjecture of equivalence between D-term strings and wrapped D-branes of Type II theory. Knowledge of the geometry of the flat direction "landscape" of a D-term string model could yield information about the dual brane model. It is hoped that the techniques encountered will be of benefit in extending the viability of the quasi-realistic phenomenologies already developed.

description: In this paper, we seek a possible route for accelerating the agricultural growth in tropical monsoon Asia in the face of increasing population pressure on limited land resources. According to a postulate of classical economists like Ricardo [18], population pressure on limited land resources will result eventually in agricultural and economic stagnation characterized by high food prices and low real wage rates that are barely sufficient for subsistence. The classical view has been challenged by Boserup [3] and Clark and Haswell [4], who argue that the population pressure will induce changes in both agricultural technology and agrarian structure so as to increase the intensity of land utilization. Hayami and Ruttan have provided another perspective, showing how countries like Japan, unfavorably endowed with land resources, could achieve rates of growth in agricultural output as high as those favorably endowed, like the United States, by developing technology appropriate to their resources [8]. The question here is whether the mechanism for inducing institutional and technological changes in response to population pressure for increased land utilization is, in fact, operating in countries in tropical monsoon Asia today. If so, what policies would be appropriate to facilitate those changes, given the specific environmental and economic conditions in those countries? We attempt to answer such questions by studying agricultural development in the Philippines during the past two decades. A major change in the agricultural growth pattern in the Philippines is identified: a shift from area expansion, continually opening new land for cultivation, to expansion through intensified land utilization. We try also to show that the factors underlying this basic shift are changes in the relative costs of those alternatives for increasing agricultural output. It has to be emphasized that this paper is designed to suggest a broad hypothesis rather than to provide conclusive evidence. Our analysis is bound to be highly conjectural because of the stringent limitations of data available in the Philippines.

description: Various sum rules for multiple giant dipole resonance states are derived. For the triple giant dipole resonance states, the energy-weighted sum of the transition strengths requires a model to be related to those of the single and double giant dipole resonance states. It is also shown that the non-diagonal matrix elements of the double commutator between the dipole operator and the nuclear Hamiltonian give useful identities for the excitation energy and transition strength of each excited state. Using those identities, the relationship between width of the single dipole state and those of the multiple ones is qualitatively discussed.

description: We address the question of the Lorentz nature of the effective long-range interquark interaction generated by the QCD string with quarks at the ends. Studying the Dyson-Schwinger equation for a heavy-light quark-antiquark system, we demonstrate explicitly how a Lorentz-scalar interaction appears in the Diraclike equation for the light quark, as a consequence of chiral symmetry breaking. We argue that the effective interquark interaction in the Hamiltonian of the QCD string with quarks at the ends stems from this effective scalar interaction.

description: Time series and cross-sectional data for 18 years on 26 N.S.W. wheat-sheep properties are combined to test whether farms that grew in size over time reaped the postulated size economies derived from the cross-sectional statistical cost functions. Realised economies of farms that remained in the industry and changed in size during the 18-year period were found to be significantly greater than measured potential economies from 'static' cost functions would have suggested. The 'dynamic economies of growth' differed significantly amongst farms indicating there was no single economy of size curve along which farms moved.
Dreamcatcher 22 : commissions of inquiry and Aboriginal criminal justice reforms
Creators: name: Schlecker, Regan Dawn
Publisher: name: University of British Columbia

description: The last decade has seen the development of an unprecedented profile for aboriginal concerns over the inadequacies of the criminal justice system. This thesis examines the major commissions of inquiry that were established to address criminal justice reforms for aboriginal Canadians. Through a comparison of these inquiries, it is my intention to provide a greater understanding as to why some commissions have had a more positive role to play in initiating policy change, while others have been less than satisfactory in promoting the needs of aboriginal persons. Analysis reveals that commissions of inquiry are most often established to address more general concerns about the impact of the criminal justice system on aboriginal peoples, rather than to investigate specific cases in which there was a miscarriage of justice. My findings also reveal that the current criminal justice system can and should be improved, without in any way detracting from the movement toward the larger social, political and economic goal of self- determination. Due to the fact that autonomous solutions remain prevalent in the academic literature, future inquiries will be required to acknowledge this perspective. An appreciation of the variety of concerns held by aboriginal individuals can only be made possible through extensive consultation with aboriginal communities and utilizing creative and innovative means of gathering research. By providing an open process, commissions will be able to encompass views that may not be prevalent in academic circles, but accepted at a grass roots level. On the much larger question of the policy impact of commissions of inquiry, they have been useful institutions for opening up the policy debate in regards to criminal justice reforms for aboriginal Canadians. Frequently these inquiries have been faulted because their specific recommendations are not accepted. However, inquiries are valuable because they provide one of the few occasions for defining public issues, including debate about reformist and radical conceptions of the issues. Consequently it is more useful to assess commissions of inquiry for their role in the development of policy debate.
