description: Στο άρθρο αυτό, μελετάται ο ρόλος των νέων τεχνολογιών στην επιστήμη της ερ-γοθεραπείας-φυσικοθεραπείας και στα άτομα με αναπηρία. Η εξέλιξη της τεχνολογίας δεν θα μπορούσε να μην επηρεά-σει θετικά την διαδικασία της αποκατάστασης που ακολουθείται από τους επαγγελματίες εργοθεραπευτές και φυσικοθεραπευτές. Σήμερα, έχει δημι-ουργηθεί πληθώρα ειδικών τεχνολογι-κών βοηθημάτων, που αναφέρονται με τον όρο «υποστη-ρικτικές τεχνολογίες» που βασί-ζονται σε τεχνολογίες όπως οι αισθητήρες (κίνησης, φωτός), η αναγνώριση φωνής, με σκοπό να βοηθήσουν άτομα με ήπια ή βαριά αναπηρία, άτομα που πάσχον από την νόσο Alzheimer, άτομα που χρειάζονται αποκατάσταση μετά από εγκεφαλικό ή καρδιακό επεισόδιο και σε παιδιά με αυτι-σμό. Η τεχνολογία διακατέχει σχεδόν κάθε τομέα στη ζωή του ανθρώ-που. Και στον τομέα της εργοθε-ραπείας η τεχνολογία έχει βοηθήσει τους επαγγελματίες ερ-γοθεραπευτές σε μεγάλο βαθμό. Σήμερα έχουν δημιουργηθεί αρκετές τε-χνολογικές συσκευές, οι οποίες βοηθούν το ασθενή στην αποκατάσταση και προ-σαρμόζονται ανάλογα με το είδος και την σοβαρότητα της περίπτωσης του. Ο όρος «βοηθητικές» τεχνολογίες, ο οποίος χρησιμοποιείται πολλές φορές στην επιστήμη της εργοθεραπείας και φυσικοθεραπείας, αντιπροσωπεύει όλες εκείνες τις συσκευές (hardware) αλλά και ειδικά λογισμικά (software) που βοηθούν στην γρηγορότερη και πιο αποτελεσμα-τική αποκατάσταση του ασθενή. Τα άτομα με αναπηρία έχουν μόνιμες ή προσωρινές βλάβες, ανικανότητες, αδυ-ναμίες ή συνδυασμό των παραπάνω, που προέρχονται από φυσική, ψυχική ή νοητική ανεπάρκεια και ειδικότερα σω-ματικά ανάπηρα χαρακτηρίζονται τα άτομα με αισθητηριακές και κινητικές αναπηρίες. όπως οι τυφλοί, οι κωφοί, οι άνθρωποι χωρίς ομιλία ή με εγκεφαλική παράλυση. Η αναπηρία μπορεί να είναι εγγενής ή επίκτητη (Νικολαϊδου, 2005). Η εκπαίδευση των ΑΜΕΑ ξεκίνησε γύρω στα 1700. Ο Rousseau τόνισε την αξία της παιδικής ηλικίας: «Η παιδική ηλικία έχει δικούς τι/ς τρόπους να αισθάνεται, να βλέπει και να σκέφτεται. Τίποτα δεν είναι παράλογο από το να θέλουμε να αντικαταστήσουμε αυτούς τους τρόπους με το δικό μας» (Brown, 1939). Η μελέτη των προβλημάτων του παιδιού άρχισε ουσιαστικά προς τα τέλη του 18ου αιώνα και έχει τις ρίζες της στις επιστήμες της παιδαγωγικής, της ψυχολογίας και της κοινωνιολογίας. Το ενδιαφέρον για την εκπαίδευση των παιδιών με ειδικές ανάγκες στηρίχτηκε στην ενδυνάμωση της ειδικής αγωγής, της ψυχολογίας καθώς και της μελέτης της γνωστικής ανάπτυξης (Τζουριάδου,1995)

description: We compute the emission of gravitational radiation from pulsating white dwarfs. This is done by using an up-to-date stellar evolutionary code coupled with a state-of-the-art pulsational code. The emission of gravitational waves is computed for a standard 0.6 solar masses white dwarf with a liquid carbon-oxygen core and a hydrogen-rich envelope, for a massive DA white dwarf with a partially crystallized core for which various l=2 modes have been observed (BPM 37093) and for PG 1159-035, the prototype of the GW Vir class of variable stars, for which several quadrupole modes have been observed as well. We find that these stars do not radiate sizeable amounts of gravitational waves through their observed pulsation g-modes, in line with previous studies. We also explore the possibility of detecting gravitational waves radiated by the f-mode and the p-modes. We find that in this case the gravitational wave signal is very large and, hence, the modes decay very rapidly. We also discuss the possible implications of our calculations for the detection of gravitational waves from pulsating white dwarfs within the framework of future space-borne interferometers like LISA.

description: We propose a theoretical protocol for quantum logic gates between two Josephson junction charge-phase qubits through the control of their coupling to a large junction. In the low excitation limit of the large junction when $E_{J}\gg E_{c}$, it behaves effectively as a quantum data-bus mode of a harmonic oscillator. Our protocol is efficient and fast. In addition, it does not require the data-bus to stay adiabatically in its ground state, as such it can be implemented over a wide parameter regime independent of the data-bus quantum state.

description: The gravitational $\mathcal{S}$-matrix defined with an infrared (IR) cutoff factorizes into hard and soft factors. The soft factor is universal and contains all the IR and collinear divergences. Here we show, in a momentum space basis, that the intricate expression for the soft factor is fully reproduced by two boundary currents, which live on the celestial sphere. The first of these is the supertranslation current, which generates spacetime supertranslations. The second is its symplectic partner, the Goldstone current for spontaneously broken supertranslations. The current algebra has an off-diagonal level structure involving the gravitational cusp anomalous dimension and the logarithm of the IR cutoff. It is further shown that the gravitational memory effect is contained as an IR safe observable within the soft $\mathcal{S}$-matrix.

title: Representing science education in UK newspapers : a case study on the controversy surrounding teaching the theory of evolution and creationism in science classes
Creators: name: Allgaier, Joachim
Publisher: name: The Open University
Year: 2008

description: The thesis examines representations of science education in UK newspapers and focuses on the role of expert sources in a controversy about the teaching of creationism alongside the theory of evolution in science classrooms. The newspaper reporting revolved around the City Technology College Emmanuel College in Gateshead, mainly in Spring 2002. The empirical research focused on two connected media elements: newspaper content and newspaper production. A quantitative and qualitative approach to analysing media content examined 287 newspaper articles from 20 UK newspapers, from I January 2002 to 20 February 2004, inclusive. The production analysis was based on semi-structured interviews with media professionals. The analysis of media content shows that the debate around Emmanuel College consisted of several related controversial issues. A range of expert sources were quoted in the articles, using various argumentation lines to address the issues of the controversy. The way expert sources were described by the journalists mainly seemed to enhance the credibility of those supporting the scientific consensus. Further analysis shows that some experts formed heterogeneousc oalitions of experts calling for action. Collaborative networks of experts appeared as efforts to enhance credibility and gain access to the media. The evidence presented in this thesis points to the importance of understanding expertise not only in individual but also in collective terms and to investigate expertise in terms of the argumentation lines reported. The analysis of semistructured interviews with media professionals demonstrates that the specialism of correspondents (e. g. on covering science or education) could influence which expert sources were selected, how they were represented and whether newspaper accounts were balanced or not. This influenced how reports were framed. Overall, the thesis demonstrates a more complex conceptualisation of expertise, one where experts are mobilised to conduct boundary work in key sites: media reporting and the National Curriculum for Science.

description: Previously reported works on the spectrum of Cs VII are critically studied using supplementary spectrograms recorded on a 3 m normal incidence vacuum spectrograph in the wavelength region 300-1240 A at the Antigonish laboratory (Canada). We confirmed the results of the earlier work of Gayasov and Joshi on this spectrum. Our analysis is supported by extended calculations with the pseudo-relativistic Hartree-Fock (HFR) method with superposition of configuration interactions implemented in Cowan's suite of codes. In this critical evaluation, in addition to the accurate energy levels of Cs VII with their uncertainties, observed and Ritz wavelengths with uncertainties and transition probabilities, the uniformly-scaled intensities of Cs VII lines are also presented. A total of 196 lines attributed to 197 transitions enabled us to optimize the energy values of 72 levels in Cs VII spectrum. Furthermore, Ritz wavelengths of 141 possibly observable lines are provided along with their transition probabilities.

description: Using time resolved ultrafast spectroscopy, we have demonstrated that the far infrared (FIR) excitations in ferroelectric crystals may be modified through an arsenal of control techniques from the fields of guided waves, geometrical and Fourier optics, and optical pulse shaping. We show that LiNbO3 and LiTaO3 crystals of 10-250 micron thickness behave as slab waveguides for phonon-polaritons, which are admixtures of electromagnetic waves and lattice vibrations, when the polariton wavelength is on the order of or greater than the crystal thickness. Furthermore, we show that ferroelectric crystals are amenable to processing by ultrafast laser ablation, allowing for milling of user-defined patterns designed for guidance and control of phonon-polariton propagation. We have fabricated several functional structures including THz rectangular waveguides, resonators, splitters/couplers, interferometers, focusing reflectors, and diffractive elements. Electric field enhancement has been obtained with the reflective structures, through spatial shaping, of the optical excitation beam used for phonon-polariton generation, and through temporal pulse shaping to permit repetitive excitation of a phonon-polariton resonant cavity.

description: This article describes a method for creating applications for cluster computing systems using the parallel BSF skeleton based on the original BSF (Bulk Synchronous Farm) model of parallel computations developed by the author earlier. This model uses the master/slave paradigm. The main advantage of the BSF model is that it allows to estimate the scalability of a parallel algorithm before its implementation. Another important feature of the BSF model is the representation of problem data in the form of lists that greatly simplifies the logic of building applications. The BSF skeleton is designed for creating parallel programs in C++ using the MPI library. The scope of the BSF skeleton is iterative numerical algorithms of high computational complexity. The BSF skeleton has the following distinctive features. - The BSF-skeleton completely encapsulates all aspects that are associated with parallelizing a program. - The BSF skeleton allows error-free compilation at all stages of application development. - The BSF skeleton supports OpenMP programming model and workflows.

description: The probability that a transient Markov chain, or a Brownian path, will ever visit a given set Lambda, is classically estimated using the capacity of Lambda with respect to the Green kernel G(x,y). We show that replacing the Green kernel by the Martin kernel G(x,y)/G(0,y) yields improved estimates, which are exact up to a factor of 2. These estimates are applied to random walks on lattices, and also to explain a connection found by R. Lyons between capacity and percolation on trees.

The role of reproductive experience on hippocampus-dependent spatial memory, adult hippocampal neurogenesis, and corticosterone in the rat dam
Creators: name: Pawluski, Jodi Lynn
Publisher: name: University of British Columbia

description: Pregnancy and the postpartum period have remarkable effects on cognition in the mother. Interestingly, motherhood results in enhanced spatial memory in the rodent. This thesis aimed to determine the role of reproductive experience (number of times pregnant and maternal) on enhanced hippocampus-dependent spatial memory in the mother, as well as the neural and hormonal correlates of this effect. Chapter 2 demonstrates that reproductive experience differentially affects spatial memory performance at the time of weaning resulting in enhanced memory performance in primiparous rats compared to nulliparous rats, with a trend toward enhanced memory performance in multiparous compared to nulliparous rats. Chapter 3 demonstrates that the enhanced spatial memory in primiparous rats persists after the time of weaning and is not due to pregnancy or pup-exposure alone. Chapter 4 demonstrates that reproductive experience results in decreased cell proliferation and cell survival in the dentate gyrus during the postpartum in primiparous rats and multiparous rats. Furthermore primiparous rats had decreased levels of cell survival compared to multiparous rats, and pup-exposed nulliparous females had increased levels of cell proliferation and cell death after brief pup-exposure. Chapter 5 demonstrates that primiparous rats have significantly elevated total corticosterone in the early postpartum period as well as lower CBG during the postpartum period. Thus, taken together the results from the experiments suggest that the enhancement in hippocampus-dependent spatial memory seen in primiparous and multiparous rats is coincident with reduced hippocampal neurogenesis, increased corticosterone, and decreased corticosteroid binding globulin (CBG) during the postpartum period in the mother. These findings demonstrate that motherhood is a time of marked neural plasticity in the hippocampus, an area of the brain not traditionally associated with motherhood.

description: In real life, providing security for a set of large areas by covering the area with Unmanned Aerial Vehicles (UAVs) is a difficult problem that consist of multiple objectives. These difficulties are even greater if the area coverage must continue throughout a specific time window. We address this by considering a Vehicle Routing Problem with Time Windows (VRPTW) variation in which capacity of agents is one and each customer (target area) must be supplied with more than one vehicles simultaneously without violating time windows. In this problem, our aim is to find a way to cover all areas with the necessary number of UAVs during the time windows, minimize the total distance traveled, and provide a fast solution by satisfying the additional constraint that each agent has limited fuel. We present a novel algorithm that relies on clustering the target areas according to their time windows, and then incrementally generating transportation problems with each cluster and the ready UAVs. Then we solve transportation problems with the simplex algorithm to generate the solution. The performance of the proposed algorithm and other implemented algorithms to compare the solution quality is evaluated on example scenarios with practical problem sizes.

description: We discuss the role that interactions play in the non-commutative structure that arises when the relative coordinates of two interacting particles are projected onto the lowest Landau level. It is shown that the interactions in general renormalize the non-commutative parameter away from the non-interacting value $\frac{1}{B}$. The effective non-commutative parameter is in general also angular momentum dependent. An heuristic argument, based on the non-commutative coordinates, is given to find the filling fractions at incompressibilty, which are in general renormalized by the interactions, and the results are consistent with known results in the case of singular magnetic fields.

description: Spectral imaging is a fundamental diagnostic technique with widespread application. Conventional spectral imaging approaches have intrinsic limitations on spatial and spectral resolutions due to the physical components they rely on. To overcome these physical limitations, in this paper, we develop a novel multi-spectral imaging modality that enables higher spatial and spectral resolutions. In the developed computational imaging modality, we exploit a diffractive lens, such as a photon sieve, for both dispersing and focusing the optical field, and achieve measurement diversity by changing the focusing behavior of this lens. Because the focal length of a diffractive lens is wavelength-dependent, each measurement is a superposition of differently blurred spectral components. To reconstruct the individual spectral images from these superimposed and blurred measurements, model-based fast reconstruction algorithms are developed with deep and analytical priors using alternating minimization and unrolling. Finally, the effectiveness and performance of the developed technique is illustrated for an application in astrophysical imaging under various observation scenarios in the extreme ultraviolet (EUV) regime. The results demonstrate that the technique provides not only diffraction-limited high spatial resolution, as enabled by diffractive lenses, but also the capability of resolving close-by spectral sources that would not otherwise be possible with the existing techniques. This work enables high resolution multi-spectral imaging with low cost designs for a variety of applications and spectral regimes.

description: We describe a method of implementing the axisymmetric evolution of general-relativistic hydrodynamics and magnetohydrodynamics through modification of a multipatch grid scheme. In order to ease the computational requirements required to evolve the post-merger phase of systems involving binary compact massive objects in numerical relativity, it is often beneficial to take advantage of these system's tendency to rapidly settle into states that are nearly axisymmetric, allowing for 2D evolution of secular timescales. We implement this scheme in the spectral Einstein code and show the results of application of this method to four test systems including viscosity, magnetic fields, and neutrino radiation transport. Our results show that this method can be used to quickly allow already existing 3D infrastructure that makes use of local coordinate system transformations to be made to run in axisymmetric 2D with the flexible grid creation capabilities of multipatch methods. Our code tests include a simple model of a binary neutron star postmerger remnant, for which we confirm the formation of a massive torus which is a promising source of post-merger ejecta.

description: Sharp localization transitions of chiral edge states in disordered quantum wires, subject to strong magnetic field, are shown to be driven by crossovers from two- to one-dimensional localization of bulk states. As a result, the two-terminal conductance is found to exhibit at zero temperature discontinuous transitions between {\it exactly} integer plateau values and zero, reminiscent of first order phase transitions. We discuss the corresponding phase diagram. The spin of the electrons is shown to result in a multitude of phases, when the spin degeneracy is lifted by the Zeeman energy. The width of conductance plateaus is found to depend sensitively on the spin flip rate $1/τ_s$.

description: PandaX-II has analyzed their complete data set of the electron recoil energy spectrum and has confirmed the XENON1T (1-7) keV excess, although the excess was also found compatible with the total background. Treating the background as well known, in which case it provides a good fit to the observed spectrum, one can expect stronger constraints on any new physics model with this data. With this motivation, we derive constraints on the new general vector (V), axial-vector (A), scalar (S) and pseudoscalar (P) interactions if any of them contribute to the neutrino-electron elastic scattering. The derived constraints on the couplings at $90\%$ C.L., respectively, are $g_{V^{^{\prime }}} \lesssim 32 \times 10^{-7}$ for the mediator mass ${\lesssim 10}$ keV, $g_{A^{^{\prime }}} \lesssim 34 \times 10^{-7}$ for mass ${\lesssim 10}$ keV, $g_{S}\lesssim 49 \times 10^{-7}$ for mass ${\lesssim 20}$ keV and $g_{P} \lesssim 67 \times 10^{-7}$ for mass ${\lesssim 30}$ keV.

description: The effect of a unidirectional periodic potential on the orientation of the stripe state is studied for the two-dimensional electron system at half-filled high Landau levels. By considering a quantum well with two electric subbands, it is found that the stripe is parallel to the external potential for weak modulation and is orthogonal for strong modulation. In the intermediate range, the orientation of the stripe changes from orthogonal to parallel as the electron density is increased. This result explains the recent experiment performed by J. Zhu {\it et al} that the anisotropy axis at half-filled high Landau levels rotates by $90^0$ by increasing the electron density. It also supports the suggestion that the stripes is pinned by the native surface morphology at the interface of the heterojunction.

description: While both X-ray emission and Sunyaev-Zel'dovich (SZ) temperature fluctuations are generated by the warm-hot gas in dark matter halos, the two observables have different dependence on the underlying physical properties, including the gas distribution. A cross-correlation between the soft X-ray background (SXRB) and the SZ sky may allow an additional probe on the distribution of warm-hot gas at intermediate angular scales and redshifts complementing studies involving clustering within SXRB and SZ separately. Using a halo approach, we investigate this cross-correlation analytically. The two contributions are correlated mildly with a correlation coefficient of $\sim0.3$, and this relatively low correlation presents a significant challenge for its detection. The correlation, at small angular scales, is affected by the presence of radiative cooling or preheating and provides a probe on the thermal history of the hot gas in dark halos. While the correlation remains undetectable with CMB data from the WMAP satellite and X-ray background data from existing catalogs, upcoming observations with CMB missions such as Planck, for the SZ side, and an improved X-ray map of the large scale structure, such as the one planned with DUET mission, may provide a first opportunity for a reliable detection of this cross-correlation.

description: Self-consistent simulations of neoclassical and electrostatic turbulent transport in a DIII-D H-mode edge plasma under resonant magnetic perturbations (RMPs) have been performed using the global total-f gyrokinetic particle-in-cell code XGC, in order to study density-pump out and electron heat confinement. The RMP field is imported from the extended magneto-hydrodynamics (MHD) code M3D-C1, taking into account the linear two-fluid plasma response. With both neoclassical and turbulence physics considered together, the XGC simulation reproduces two key features of experimentally observed edge transport under RMPs: increased radial particle transport in the pedestal region that is sufficient to account for the experimental pump-out rate, and suppression of the electron heat flux in the steepest part of the edge pedestal. In the simulation, the density fluctuation amplitude of modes moving in the electron diamagnetic direction increases due to interaction with RMPs in the pedestal shoulder and outward, while the electron temperature fluctuation amplitude decreases.

description: We analyse systems analogous to the Milky Way (MW) in the EAGLE cosmological hydrodynamics simulation in order to deduce the likely structure of the MW's dark matter halo. We identify MW-mass haloes in the simulation whose satellite galaxies have similar kinematics and spatial distribution to those of the bright satellites of the MW, specifically systems in which the majority of the satellites (8 out of 11) have nearly co-planar orbits that are also perpendicular to the central stellar disc. We find that the normal to the common orbital plane of the co-planar satellites is well aligned with the minor axis of the host dark matter halo, with a median misalignment angle of only $17.3^\circ$. Based on this result, we infer that the minor axis of the Galactic dark matter halo points towards $(l,b)=(182^\circ,-2^\circ)$, with an angular uncertainty at the 68 and 95 percentile confidence levels of 22$^\circ$ and 43$^\circ$ respectively. Thus, the inferred minor axis of the MW halo lies in the plane of the stellar disc. The halo, however, is not homologous and its flattening and orientation vary with radius. The inner parts of the halo are rounder than the outer parts and well-aligned with the stellar disc (that is the minor axis of the halo is perpendicular to the disc). Further out, the halo twists and the minor axis changes direction by $90^\circ$. This twist occurs over a very narrow radial range and reflects variations in the filamentary network along which mass was accreted into the MW.

Efficient trainability of linear optical modules in quantum optical neural networks

description: The existence of "barren plateau landscapes" for generic discrete variable quantum neural networks, which obstructs efficient gradient-based optimization of cost functions defined by global measurements, would be surprising in the case of generic linear optical modules in quantum optical neural networks due to the tunability of the intensity of continuous variable states and the relevant unitary group having exponentially smaller dimension. We demonstrate that coherent light in $m$ modes can be generically compiled efficiently if the total intensity scales sublinearly with $m$, and extend this result to cost functions based on homodyne, heterodyne, or photon detection measurement statistics, and to noisy cost functions in the presence of attenuation. We further demonstrate efficient trainability of $m$ mode linear optical quantum circuits for variational mean field energy estimation of positive quadratic Hamiltonians for input states that do not have energy exponentially vanishing with $m$.

Simulation and theory of vibrational phase relaxation in the critical and supercritical nitrogen: Origin of observed anomalies

description: We present results of extensive computer simulations and theoretical analysis of vibrational phase relaxation of a nitrogen molecule along the critical isochore and also along the gas-liquid coexistence. The simulation includes all the different contributions [atom-atom (AA), vibration-rotation (VR) and resonant transfer] and their cross-correlations. Following Everitt and Skinner, we have included the vibrational coordinate ($q$) dependence of the interatomic potential. It is found that the latter makes an important contribution. The principal important results are: (a) a crossover from a Lorentzian-type to a Gaussian line shape is observed as the critical point is approached along the isochore (from above), (b) the root mean square frequency fluctuation shows nonmonotonic dependence on the temperature along critical isochore, (c) along the coexistence line and the critical isochore the temperature dependent linewidth shows a divergence-like $λ$-shape behavior, and (d) the value of the critical exponents along the coexistence and along the isochore are obtained by fitting. The origin of the anomalous temperature dependence of linewidth can be traced to simultaneous occurrence of several factors, (i) the enhancement of negative cross-correlations between AA and VR contributions and (ii) the large density fluctuations as the critical point (CP) is approached. The former makes the decay faster so that local density fluctuations are probed on a femtosecond time scale. A mode coupling theory (MCT) analysis shows the slow decay of the enhanced density fluctuations near critical point. The MCT analysis demonstrates that the large enhancement of VR coupling near CP arises from the non-Gaussian behavior of density fluctuation and this enters through a nonzero value of the triplet direct correlation function.

Charting citizenship : the political participation of immigrants in Richmond and Surrey, BC
Creators: name: Rose, John Stanley
Publisher: name: University of British Columbia
Year: 2011

description: This thesis presents an examination of immigrant political participation in Richmond and Surrey, BC, during the 1990s, with a particular focus on Chinese-Canadians from Hong Kong and South Asian-Canadians from the Punjab region of India. The purpose of the thesis is to examine the extent and direction of citizenship, as measured by political participation, among these Canadian citizens. The research addresses various contemporary theories on citizenship and immigrant settlement: how immigrants are being incorporated as citizens in their country of settlement, and/or sustain political transnational activities that span the borders of nation-states. Electoral returns for the 1991, 1996, and 2001 British Columbia Provincial General Elections, and returns for the 1993, 1997, and 2000 Canadian Federal General Elections, are compared with census data for Richmond and Surrey to assess the relationship between immigrant status, ethnic origin, and voter turnout. Focus groups and interviews with 100 Punjabi-origin and Hong Kong-origin residents are also drawn upon to assess voter participation rates, as well as participation in extra electoral political activities, non-electoral politics, and transnational political activities. The research finds little evidence of transnational political activity, and that most participants' political energies are directed towards formal Canadian electoral politics, especially voting. Additional electoral and non-electoral participation was also evident. Electoral analysis indicates that immigrant status is only modestly related with voter turnout, though by the turn of the 2000s, immigrant status--especially recent immigrant status--becomes increasingly associated with declines in voter participation. The research also finds, in the realm of voting and other electoral and non-electoral activities, little differentiation in the overall participation rates between Hong Kong-origin Chinese Canadians and Punjabi-origin South Asian Canadians. Their considerable participation in formal Canadian politics notwithstanding, the thesis also finds that immigrant-origin, ethnic minority citizens harbour considerable concerns with the way in which the Canadian political system addresses their concerns, and believe that co-ethnic representation is necessary to make the political system more responsive and representative.

description: Blockchain or Distributed Ledger Technology is a disruptive technology that provides the infrastructure for developing decentralized applications enabling the implementation of novel business models even in traditionally centralized domains. In the last years it has drawn high interest from the academic community, technology developers and startups thus lots of solutions have been developed to address blockchain technology limitations and the requirements of applications software engineering. In this paper, we provide a comprehensive overview of DLT solutions analyzing the addressed challenges, provided solutions and their usage for developing decentralized applications. Our study reviews over 100 blockchain papers and startup initiatives from which we construct a 3-tier based architecture for decentralized applications and we use it to systematically classify the technology solutions. Protocol and Network Tier solutions address the digital assets registration, transactions, data structure, and privacy and business rules implementation and the creation of peer-to-peer networks, ledger replication, and consensus-based state validation. Scaling Tier solutions address the scalability problems in terms of storage size, transaction throughput, and computational capability. Finally, Federated Tier aggregates integrative solutions across multiple blockchain applications deployments. The paper closes with a discussion on challenges and opportunities for developing decentralized applications by providing a multi-step guideline for decentralizing the design of traditional systems and implementing decentralized applications.
