Existing arrangements and procedures for generating and analyzing information : a comparative evaluation of several greater Vancouver Regional District Park and/or recreation agencies
Creators: name: Doyle, Brian Owen
Publisher: name: University of British Columbia
Year: 2010

description: One major task faced by public recreation planners is the determination of the type, quantity and quality of future recreation that will be demanded. A second follow-up job involves the attempt to maximize user satisfaction by providing adequate recreation services and facilities while allowing for limitations in both recreation resources and agency capability. Prerequisite to the successful completion of these two tasks is the presence of a sound research framework that is complemented by relevant information and proper analysis techniques. The major concern of this thesis was to describe, in some detail, the present state of recreational planning in the Greater Vancouver Regional District. In particular, research was directed towards the assessment of existing arrangements and procedures for generating and analyzing-recreation information. Three major objectives were realized: (1) to evaluate the planning methodologies presently used in the assessment of the supply and demand for recreation resources; (2) to assess the suitability and capability of public park and/or recreation agencies to undertake continuous, efficient and relevant recreational planning; and (3) to propose changes in the present arrangements and procedures for recreational planning. The methodology used in this study followed two related and complementary steps. In the initial phase, a 'comprehensive recreation planning model' was developed. It consisted of three sub-models of investigation: demand, supply and demand-supply linkage analyses. The latter step focused on a comparative evaluation of the recreational planning approach and the recreation agency i.e. it's capability and suitability for research, for one regional and twelve municipal park and/or recreation agencies in the Greater Vancouver Regional District, via the 'comprehensive recreation planning model' and the seventy-seven criteria that were used as indicators of quality. Results of the comparative evaluation indicated significant deficiencies in several aspects of the recreational planning approaches currently being used. Major limitations in the research capability of the recreation agencies were linked to inadequate research budgets, and to insufficient data generation and processing ability. Further, the majority of agencies examined showed a need for more information regarding the recreation clientele i.e. their demands, preferences, degrees of preference, leisure time budgets, and their past education and experiences related to public recreation; and, the recreation resources i.e. land, facilities and services by type, nature and quantity.

description: Building on mode-coupling-theory calculations, we report a novel scenario for multiple glass transitions in a purely repulsive spherical potential: the square-shoulder. The liquid-glass transition lines exhibit both melting by cooling and melting by compression as well as associated diffusion anomalies, similar to the ones observed in water. Differently from all previously investigated models, here for small shoulder widths a glass-glass line is found that is disconnected from the liquid phase. Upon increasing the shoulder width such a glass-glass line merges with the liquid-glass transition lines, featuring two distinct endpoint singularities that give rise to logarithmic decays in the dynamics. These findings can be explained analytically by the interplay of different repulsive length scales.

Microscopic origin of magnetism and magnetic interactions in ferropnictides

description: One year after their initial discovery, two schools of thought have crystallized regarding the electronic structure and magnetic properties of ferropnictide systems. One postulates that these are itinerant weakly correlated metallic systems that become magnetic by virtue of spin-Peierls type transition due to near-nesting between the hole and the electron Fermi surface pockets. The other argues these materials are strongly or at least moderately correlated, the electrons are considerably localized and close to a Mott-Hubbard transition, with the local magnetic moments interacting via short-range superexchange. In this paper we argue that neither picture is fully correct. The systems are moderately correlated, but with correlations driven by Hund's rule coupling rather than by the on-site Hubbard repulsion. The iron moments are largely local, driven by Hund's intra-atomic exchange. Superexchange is not operative and the interactions between the Fe moments are considerably long-range and driven mostly by one-electron energies of all occupied states.

description: Oral route colon-targeted drug delivery systems (CDDSs) are desirable for the treatment of ulcerative colitis (UC). However, CDDSs are challenging owing to the physiological and anatomical barriers associated with the gastrointestinal tract (GIT). In this study, we developed an effective enzyme-triggered controlled release system using curcumin–cyclodextrin (CD–Cur) inclusion complex as core and low molecular weight chitosan and unsaturated alginate resulting nanoparticles (CANPs) as shell. The formed CD–Cur–CANPs showed a narrow particle-size distribution and a compact structure. In vitro drug release determination indicated that CD–Cur–CANPs showed pH-sensitive and α-amylase-responsive release characteristics. Furthermore, in vivo experiments demonstrated that oral administration of CD–Cur–CANPs had an efficient therapeutic efficacy, strong colonic biodistribution and accumulation, rapid macrophage uptake, promoted colonic epithelial barrier integrity and modulated production of inflammatory cytokines, reshaped the gut microbiota in mice with dextran sodium sulfate (DSS)-induced colitis. Taken together, our synthetic CD–Cur–CANPs are a promising synergistic colon-targeted approach for UC treatment.
Electronic and phononic Raman scattering in detwinned YBa$_2$Cu$_3$O$_{6.95}$ and Y$_{0.85}$Ca$_{0.15}$Ba$_2$Cu$_3$O$_{6.95}$: s-wave admixture to the $d_{x^2-y^2}$-wave order parameter

description: Inelastic light (Raman) scattering has been used to study electronic excitations and phonon anomalies in detwinned, slightly overdoped YBa$_2$Cu$_3$O$_{6.95}$ and moderately overdoped Y$_{0.85}$Ca$_{0.15}$Ba$_2$Cu$_3$O$_{6.95}$ single crystals. In both samples modifications of the electronic pair-breaking peaks when interchanging the a- and b-axis were observed. The lineshapes of several phonon modes involving plane and apical oxygen vibrations exhibit pronounced anisotropies with respect to the incident and scattered light field configurations. Based on a theoretical model that takes both electronic and phononic contributions to the Raman spectra into account, we attribute the anisotropy of the superconductivity-induced changes in the phonon lineshapes to a small s-wave admixture to the $d_{x^2-y^2}$ pair wave-function. Our theory allows us to disentangle the electronic Raman signal from the phononic part and to identify corresponding interference terms. We argue that the Raman spectra are consistent with an s-wave admixture with an upper limit of 20 percent.

description: Utilizing recent DIS measurements (σ_r, F_{2,3,L}) and data on hadronic dilepton production we determine at NNLO (3-loop) of QCD the dynamical parton distributions of the nucleon generated radiatively from valencelike positive input distributions at an optimally chosen low resolution scale (Q_0^2 < 1 GeV^2). These are compared with `standard' NNLO distributions generated from positive input distributions at some fixed and higher resolution scale (Q_0^2 > 1 GeV^2). Although the NNLO corrections imply in both approaches an improved value of χ^2, typically χ^2_{NNLO} \simeq 0.9 χ^2_{NLO}, present DIS data are still not sufficiently accurate to distinguish between NLO results and the minute NNLO effects of a few percent, despite of the fact that the dynamical NNLO uncertainties are somewhat smaller than the NLO ones and both are, as expected, smaller than those of their `standard' counterparts. The dynamical predictions for F_L(x,Q^2) become perturbatively stable already at Q^2 = 2-3 GeV^2 where precision measurements could even delineate NNLO effects in the very small-x region. This is in contrast to the common `standard' approach but NNLO/NLO differences are here less distinguishable due to the much larger 1σuncertainty bands. Within the dynamical approach we obtain α_s(M_Z^2)=0.1124 \pm 0.0020, whereas the somewhat less constrained `standard' fit gives α_s(M_Z^2)=0.1158 \pm 0.0035.

description: We have updated the classification of late-type galaxies presented in the Catalog of Isolated Galaxies (KIG) using the advanced digital sky surveys. Our search for companions around 959 KIG galaxies revealed 141 neighbors associated with 111 KIG galaxies within the mutual projection separation of less than 330 kpc and the radial velocity difference not exceeding 500 km s$^{-1}$. Typical luminosity of the companions turned out to be weaker than the luminosity of the main galaxies by more than an order of magnitude. Considering these small companions as test particles that move around the KIG galaxies along the Keplerian orbits with eccentricity of $e\simeq0.7$, we estimated the total (orbital) masses of spiral KIG galaxies. Their average orbital mass-to-$K$-band luminosity ratio, $(20.9\pm3.1) M_{\odot}/L_{\odot}$, is in a good agreement with the corresponding value for the nearby Milky Way, M31 and M81-type massive spirals. Isolated disk-shaped galaxies have an on the average 2-3 times smaller total-mass-to-stellar-mass ratio than those of isolated bulge-shaped galaxies.

description: (abridged) Recently, a new class of radio transients in the 5-GHz band was detected by Bower et al. We present new deep near-Infrared (IR) observations of the field containing these transients, and find no counterparts down to a limiting magnitude of K=20.4 mag. We argue that the bright (>1 Jy) radio transients recently reported by Kida et al. are consistent with being additional examples of the Bower et al. transients. We refer to these groups of events as "long-duration radio transients". The main characteristics of this population are: time scales longer than 30 minute but shorter than several days; rate, ~10^3 deg^-2 yr^-1; progenitors sky surface density of >60 deg^-2 (95% C.L.) at Galactic latitude ~40 deg; 1.4-5 GHz spectral slopes, f_ν~ ν^alpha, with alpha>0; and most notably the lack of any counterparts in quiescence in any wavelength. We rule out an association with many types of objects. Galactic brown-dwarfs or some sort of exotic explosions remain plausible options. We argue that an attractive progenitor candidate for these radio transients is the class of Galactic isolated old neutron stars (NS). We confront this hypothesis with Monte-Carlo simulations of the space distribution of old NSs, and find satisfactory agreement for the large areal density. Furthermore, the lack of quiescent counterparts is explained quite naturally. In this framework we find: the mean distance to events in the Bower et al. sample is of order kpc; the typical distance to the Kida et al. transients are constrained to be between 30 pc and 900 pc (95% C.L.); these events should repeat with a time scale of order several months; and sub-mJy level bursts should exhibit Galactic latitude dependence. We discuss possible mechanisms giving rise to the observed radio emission.

description: Variable stars have been identified for the first time in the very metal-poor Blue Compact dwarf galaxy IZw18, using deep multi-band (F606W, F814W)time-series photometry obtained with the Advanced Camera for Surveys (ACS) on board the Hubble Space Telescope (HST). We detected 34 candidate variable stars in the galaxy. We classify three of them as Classical Cepheids, with periods of 8.71, 125.0 and 130.3 days, respectively, and other two as long period variables with periodicities longer than a hundred days. These are the lowest metallicity Classical Cepheids known so far, thus providing the opportunity to explore and fit models of stellar pulsation fo Classical Cepheids at previously inaccessible metallicities. The period distribution of the confirmed Cepheids is markedly different from what is seen in other nearby galaxies, which is likely related to the star bursting nature of IZw18. By applying to the 8.71 days Cepheid theoretical Wesenheit (V,I) relations based on new pulsation models of Classical Cepheids specifically computed for the extremely low metallicity of this galaxy (Z=0.0004, Y=0.24), we estimate the distance modulus of IZw18 to be mu_0= 31.4pm0.2 D=19.0^{+1.8}_{-1.7}Mpc) for canonical models of Classical Cepheids, and of 31.2pm0.2 mag (D=17.4^{+1.6}_{-1.6}Mpc) using over luminous models. The theoretical modeling of the star's light curves provides mu_0=31.4pm0.1 mag, D=19.0^{+0.9}_{-0.9} Mpc, in good agreement with the results from the theoretical Wesenheit relations. These pulsation distances bracket the distance of 18.2pm1.5Mpc inferred by Aloisi et al. (2007) using the galaxy's Red Giant Branch Tip.

We review aspects of the architecture and show how L-CNNs can represent a large class of gauge invariant and equivariant functions on the lattice. We compare the performance of L-CNNs and non-equivariant networks using a non-linear regression problem and demonstrate how gauge invariance is broken for non-equivariant models.

Studies on the physiological release and insulinotropic action of gastric inhibitory polypeptide
Creators: name: Schubert, Harold Edward
Publisher: name: University of British Columbia
Year: 2010

description: The effect of highly purified gastric inhibitory polypeptide (GIP) on immunoreactive insulin (IRI) secretion in the conscious fasted dog was investigated. Significant increased in IRI release were observed with intravenous administration of three different doses of GIP. These were accompanied by depression in fasting serum glucose levels. Preliminary studies were undertaken to determine whether this insulinotropic action of GIP could be attributed to a particular segment of the GIP molecule. GIP fragments produced by cleavage with cyanogen bromide (CNBr) and trypsin (TPCK) showed no significant stimulation of IRI release. The possibility that GIP might itself enhance glucose uptake or potentiate insulin-induced glucose uptake was studied using the rat hemidiaphragm preparation. No such effect was observed. The release of IR-GIP by oral glucose and fat was investigated and this release Was shown to occur in a dose-related manner. Fat was found to be the most potent secretagoge for IR-GIP reported to date but no significant change in serum IRI levels was observed following oral fat. In light of this and other recent work, the possible involvement of GIP in carbohydrate metabolism is discussed.

description: First-principles calculations based on density functional theory have been widely used in studies of the structural, thermoelastic, rheological, and electronic properties of earth-forming materials. The exchange-correlation term, however, is implemented based on various approximations, and this is believed to be the main reason for discrepancies between experiments and theoretical predictions. In this work, by using periclase MgO as a prototype system we examine the discrepancies in pressure and Kohn-Sham energy that are due to the choice of the exchange-correlation functional. For instance, we choose local density approximation and generalized gradient approximation. We perform extensive first-principles calculations at various temperatures and volumes and find that the exchange-correlation-based discrepancies in Kohn-Sham energy and pressure should be independent of temperature. This implies that the physical quantities, such as the equation of states, heat capacity, and the Grüneisen parameter, estimated by a particular choice of exchange-correlation functional can easily be transformed into those estimated by another exchange-correlation functional. Our findings may be helpful in providing useful constraints on mineral properties %at thermodynamic conditions compatible to deep Earth. at deep Earth thermodynamic conditions.

description: The initial conditions in high energy nucleus-nucleus collisions are determined by the small momentum fraction part of the nuclear wavefunction. This is the regime of gluon saturation and the most direct way to experimentally study it would be deep inelastic scattering at a high energy electron ion collider (EIC). This talk discusses some of the connections between physics at the EIC and the initial stage of relativistic heavy ion collisions. We argue that measurements at an EIC will provide detailed high-precision information about the parameters for the initial conditions, transverse geometry and longitudinal correlations that will be crucial in understanding the initial stage of a heavy ion collision.

description: The formation of thick stellar disks in spiral galaxies is studied. Simulations of gas-rich young galaxies show formation of internal clumps by gravitational instabilities, clump coalescence into a bulge, and disk thickening by strong stellar scattering. The bulge and thick disks of modern galaxies may form this way. Simulations of minor mergers make thick disks too, but there is an important difference. Thick disks made by internal processes have a constant scale height with galactocentric radius, but thick disks made by mergers flare. The difference arises because in the first case, perpendicular forcing and disk-gravity resistance are both proportional to the disk column density, so the resulting scale height is independent of this density. In the case of mergers, perpendicular forcing is independent of the column density and the low density regions get thicker; the resulting flaring is inconsistent with observations. Late-stage gas accretion and thin disk growth are shown to preserve the constant scale heights of thick disks formed by internal evolution. These results reinforce the idea that disk galaxies accrete most of their mass smoothly and acquire their structure by internal processes, in particular through turbulent and clumpy phases at high redshift.

description: Transiting planets at young ages are key targets for improving our understanding of the evolution of exo-atmospheres. We present results of a new X-ray observation of V1298 Tau with XMM-Newton, aimed to determine more accurately the high-energy irradiation of the four planets orbiting this pre-main-sequence star, and the possible variability due to magnetic activity on short and long time scales. Following the first measurements of planetary masses in the V1298 Tau system, we revise early guesses of the current escape rates from the planetary atmospheres, employing our updated atmospheric evaporation models to predict the future evolution of the system. Contrary to previous expectations, we find that the two outer Jupiter-size planets will not be affected by any evaporation on Gyr time scales, and the same occurs for the two smaller inner planets, unless their true masses are lower than $\sim 40$ M$_\oplus$. These results confirm that relatively massive planets can reach their final position in the mass-radius diagram very early in their evolutionary history.

A geographically Isolated and Disadvantaged Areas (GIDAs), Barangay Kiorao is located in the Municipality of Kibawe, Province of Bukidnon, Mindanao, Philippines. The goal of this study is to assess land tenure rights in Kiorao. The objectives are as follows: 1) Determine the different land uses in the barangay, 2) Assess the natural resource development potential, 3) Determine the forms of land tenure arrangements in the community; and 4) Identify the key stakeholders in the land tenure arrangement. The methodology employed use of secondary land use data, participatory workshops and geographic information system (GIS). The results showed that Kiorao is an agricultural community with 44.5% of the land dedicated to crop production, tree cover likewise covers a significant area at 36.7%. The remaining natural forest is merely riparian, thus, natural resources development options will be confined to agricultural and silvicultural. Tax declaration is the form of land tenure amongst 98% of the households, while 0.5% possess a land title. A Community-based Forest Management Agreement (CBFMA) was granted, but the community has been drowned with bureaucratic and technical requirements, not being able to extract timber which they have planted. While struggling to make sense of the promised security, the community has to apply for renewal of the CBFMA, now clouded with a competing process of an ancestral domain claim. The concept of convergence among government program is much needed in this particular experience of Kiorao so that land tenure is secured for the community; settlers and indigenous peoples.

description: We study the outer-shock structure of the oxygen-rich supernova remnant G292.0+1.8, using a deep observation with the Chandra X-ray Observatory. We measure radial variations of the electron temperature and emission measure that we identify as the outer shock propagating into a medium with a radially decreasing density profile. The inferred ambient density structure is consistent with models for the circumstellar wind of a massive progenitor star rather than for a uniform interstellar medium. The estimated wind density n_H = 0.1 ~ 0.3 cm^-3) at the current outer radius (~7.7 pc) of the remnant is consistent with a slow wind from a red supergiant (RSG) star. The total mass of the wind is estimated to be ~ 15 - 40 solar mass (depending on the estimated density range), assuming that the wind extended down to near the surface of the progenitor. The overall kinematics of G292.0+1.8 are consistent with the remnant expanding through the RSG wind.

description: We calculate the frequency-dependent admittance of a phase-biased Josephson junction spanning a magnetic impurity or a spinful Coulomb-blockaded quantum dot. The local magnetic moment gives rise to Yu-Shiba-Rusinov bound states, which govern the sub-gap absorption as well as the inductive response. We model the system by a superconducting spin-polarized exchange-cotunnel junction and calculate the linear current response to an AC bias voltage, including its dependence on phase bias as well as particle-hole, and source-drain coupling asymmetry. The corresponding inductive admittance is analyzed and compared to results of a zero-bandwidth, as well as an infinite-gap approximation to the superconducting Anderson model. All three approaches capture the interaction-induced $0-π$ transition, which is reflected as a discontinuity in the adiabatic inductive response.

description: We establish a relation between entanglement of a many-body system and its diffractive properties, where the link is given by structure factors. Based on these, we provide a general analytical construction of multi-qubit entanglement witnesses. The proposed witnesses contain two-point correlations. They could be either measured in a scattering experiment or via local measurements, depending on the underlying physical system. For some explicit examples of witnesses we analyze the properties of the states that are detected by them. We further study the robustness of these witnesses with respect to noise.

description: The development of trajectory-based operations and the rolling network operations plan in European air traffic management network implies a move towards more collaborative, strategic flight planning. This opens up the possibility for inclusion of additional information in the collaborative decision-making process. With that in mind, we define the indicator for the economic risk of network elements (e.g., sectors or airports) as the expected costs that the elements impose on airspace users due to Air Traffic Flow Management (ATFM) regulations. The definition of the indicator is based on the analysis of historical ATFM regulations data, that provides an indication of the risk of accruing delay. This risk of delay is translated into a monetary risk for the airspace users, creating the new metric of the economic risk of a given airspace element. We then use some machine learning techniques to find the parameters leading to this economic risk. The metric is accompanied by an indication of the accuracy of the delay cost prediction model. Lastly, the economic risk is transformed into a qualitative economic severity classification. The economic risks and consequently economic severity can be estimated for different temporal horizons and time periods providing an indicator which can be used by Air Navigation Service Providers to identify areas which might need the implementation of strategic measures (e.g., resectorisation or capacity provision change), and by Airspace Users to consider operation of routes which use specific airspace regions.

description: Aiming to observe cosmic gamma rays in the 10 - 1000 TeV energy region, we propose a 10000 m^2 underground water-Cherenkov muon-detector (MD) array that operates in conjunction with the Tibet air-shower (AS) array. Significant improvement is expected in the sensitivity of the Tibet AS array towards celestial gamma-ray signals above 10 TeV by utilizing the fact that gamma-ray-induced air showers contain far fewer muons compared with cosmic-ray-induced ones. We carried out detailed Monte Carlo simulations to assess the attainable sensitivity of the Tibet AS+MD array towards celestial TeV gamma-ray signals. Based on the simulation results, the Tibet AS+MD array will be able to reject 99.99% of background events at 100 TeV, with 83% of gamma-ray events remaining. The sensitivity of the Tibet AS+MD array will be ~20 times better than that of the present Tibet AS array around 20 - 100 TeV. The Tibet AS+MD array will measure the directions of the celestial TeV gamma-ray sources and the cutoffs of their energy spectra. Furthermore, the Tibet AS+MD array, along with imaging atmospheric Cherenkov telescopes as well as the Fermi Gamma-ray Space Telescope and X-ray satellites such as Suzaku and MAXI, will make multiwavelength observations and conduct morphological studies on sources in the quest for evidence of the hadronic nature of the cosmic-ray acceleration mechanism.

description: X-ray polarimetry can potentially constrain the unknown geometrical shape of AGN coronae. We present simulations of the X-ray polarization signal expected from AGN coronae, assuming three different geometries, namely slab, spherical and conical. We use the fully relativistic Monte-Carlo Comptonization code monk to compute the X-ray polarization degree and angle. We explore different coronal parameters such as shape, size, location and optical depth. Different coronal geometries give a significantly different X-ray polarization signal. A slab corona yields a high polarization degree, up to 14% depending on the viewing inclination; a spherical corona yields low values, about 1-3%, while a conical corona yields intermediate values. We also find a difference of 90 degrees in polarization angle between the slab corona and the spherical or conical coronae. Upcoming X-ray polarimetry missions like IXPE will allow us to observationally distinguish among different coronal geometries in AGNs for the first time.

The influence of verbal reinforcement and experimenter self-disclosure on personality tests
Creators: name: Arlett, Christine
Publisher: name: University of British Columbia
Year: 2010

description: Experimenter self-disclosure and verbal reinforcement of subject disclosure during an interview were both predicted to result in increased subject disclosure in a subsequent testing situation, as compared with direct instructions to the subjects to be more open.. The results indicated that for male subjects, verbal reinforcement had the predicted effect, but experimenter self-disclosure did not. Female subjects were found to be more disclosive than male subjects in general, but were relatively uninfluenced by the experimenter treatment conditions. Experimenter self-disclosure was shown to result in an increase in social evaluative anxiety and in more favourable perceptions of the self and of the experimenter in the subjects concerned. Both of these factors are discussed as having counteracted any modeling effect of experimenter self-disclosure. An interpretation of the results in terms of an interaction between subject sex, experimenter sex and experimental conditions is proposed and the implications this has for the related literature, which in general has ignored such variables as subject and experimenter sex, are discussed.
Analysis of D/D translocations in man by differential staining

description: With the advent of new cytogenetic techniques, more questions can be answered concerning chromosomal rearrangements. The questions considered in this study ask which chromosomes are involved in the t(Dq Dq) translocation, where are the break points located, and what are the possible mechanisms of t(Dq Dq) translocation formation. The segregation pattern of the D/D translocation was considered when the chromosome translocation was shown to be familial. Chromosomes were obtained from leukocyte blood cultures and three differential staining techniques (Giemsa-banding, fluorescent-banding, C-banding) were used to identify the chromosomes involved in the D/D translocation. These techniques also allowed the break points in each chromosome to be estimated. Four families and a single spontaneous case were examined. The segregation pattern of the t(Dq Dq) translocation was discussed for the familial translocations. The possible mechanisms of formation of these D/D translocations was also discussed. The cytogenetic investigation revealed these general results . 1. A homologous t(14q;14q) chromosome, which appeared to be monocentric, was found in a male infant who was ascertained through an investigation of his short stature. 2. A homologous t(13q;13q) chromosome, which appeared to be dicentric, was found in a family who was ascertained through the birth of a male with numerous congenital malformations. 3. A t(13q;14q) translocation chromosome, which appeared to be dicentric, was found in a family who was ascertained through the birth of a mentally retarded male. 4. A t(13q;14q) translocation chromosome, which appeared to be monocentric, was found in a family who was ascertained through the birth of a mentally retarded male. 5. A t(13q;14q) translocation chromosome and a t(13p;14p) translocation chromosome was found in a family who was ascertained through the birth of a mentally retarded male.

description: Many cross-organization cooperation applications of blockchain-based distributed ledger technologies (DLT) do not aim at innovation at the cooperation pattern level: essentially the same ''business'' is conducted by the parties, but this time without a central party to be trusted with bookkeeping. The migration to DLT is expected to have a negative performance impact, but some DLTs, such as Hyperledger Fabric, are accepted to be much better suited performance-wise to such use cases than others. However, with the somewhat surprising, but ongoing absence of application-level performance benchmarks for DLTs, cross-DLT comparison for "classic" workloads and the evaluation of the performance impact of "blockchainification" is still ill-supported. We present the design and Hyperledger Caliper-based open implementation of a full port of the classic TPC-C benchmark to Hyperledger Fabric, complete with a structured approach for transforming the original database schema to a smart contract data model. Initial measurements about the workload characteristics that will affect the design of large-scale performance evaluations are also included.
