Agenda-setting dynamics in Canada
Creators: name: Soroka, Stuart Neil
Publisher: name: University of British Columbia
Year: 2009

description: Agenda-setting hypotheses inform political communications studies of media influence (public agenda-setting), as well as examinations of the policymaking process (policy agenda-setting). In both cases, studies concentrate on the salience of issues on actors' agendas, and the dynamic process through which these agendas change and effect each other. The results, narrowly conceived, offer a means of observing media effects or the policy process. Broadly conceived, agenda-setting analyses speak to the nature of relationships between major actors in a political system. This study differs from most past agenda-setting research in several ways. First, this project draws together public and policy agenda-setting work to build a more comprehensive model of the expanded agenda-setting process. Secondly, the modeling makes no assumptions about the directions of causal influence - econometric methods are used to establish causality, allowing for a more nuanced and accurate model of issue dynamics. Quantitative evidence is derived from a longitudinal dataset (1985-1995) including the following: a content analysis of Canadian newspapers (media agenda), 'most important problem' results from all available commercial polls (public agenda), and measures of attention to issues in Question Period, committees, Throne Speeches, government spending, and legislative initiatives (policy agenda). Data is collected for eight issues: AIDS, crime, debt/deficit, environment, inflation, national unity, taxation, and unemployment. The present study, then, is well situated to add unique information to several ongoing debates in agenda-setting studies, and provide a bird's eye view of the media-public-policy dynamics in Canadian politics. Many hypotheses are introduced and tested. Major findings include: (1) there is a Canadian national media agenda; (2) the salience of issues tends to rise and fall simultaneously across Canada, although regional variation exists based on audience attributes and issue obtrusiveness; (3) there is no adequate single measure of the policy agenda - government attention to issues must be measured at several points, and these tend to be only loosely related; (4) the agenda-setting dynamics of individual issues are directly and systematically related to attributes such as prominence and duration; (5) Canadian media and public agendas can be affected by the US media agenda.

description: Quantum computing may offer the opportunity to simulate strongly-interacting field theories, such as quantum chromodynamics, with physical time evolution. This would give access to Minkowski-signature correlators, in contrast to the Euclidean calculations routinely performed at present. However, as with present-day calculations, quantum computation strategies still require the restriction to a finite system size, including a finite, usually periodic, spatial volume. In this work, we investigate the consequences of this in the extraction of hadronic and Compton-like scattering amplitudes. Using the framework presented in Phys. Rev. D101 014509 (2020), we quantify the volume effects for various $1+1$D Minkowski-signature quantities and show that these can be a significant source of systematic uncertainty, even for volumes that are very large by the standards of present-day Euclidean calculations. We then present an improvement strategy, based in the fact that the finite volume has a reduced symmetry. This implies that kinematic points, which yield the same Lorentz invariants, may still be physically distinct in the finite-volume system. As we demonstrate, both numerically and analytically, averaging over such sets can significantly suppress the unwanted volume distortions and improve the extraction of the physical scattering amplitudes.

description: A supramolecular assembly was obtained by combining methylene blue (MB) with a natural plant extract curcumin (Curc) in a stoichiometric ratio of 1:4 in aqueous solution (90% PBS + 10% ethanol) at room temperature. The MB-Curc supramolecular assembly was evidenced by absorption and fluorescence spectroscopies and the stoichiometry and bonding constant were obtained using Cielen´s model. Its stability and photostability were evaluated by chromatographic analyzes and UV-Vis absorption. The MB-Curc avoids the aggregation of both isolated compounds and was efficient to produce singlet oxygen (ΦΔ = 0.52 ± 0.03). Its potential for photodynamic antiangiogenic treatments was evaluated through vascular effect observed in chicken chorioallantoic membrane (CAM) assay. The results showed intense damage in CAM vascular network by MBCurc after irradiation, which is higher than the effect of isolated compounds, showing a synergic vascular effect. This combination can be important to avoid cancer revascularization after photodynamic application, and improve this approach’s efficacy. The characteristics shown by MB-Curc make it a potential candidate for use in cancer treatments by photodynamic antiangiogenic therapy.

description: This study examines how sociodemographic characteristics of a household's main meal planner affect use of nutritional information concerning ingredients, health benefits, calories, sodium, vitamins/minerals, fiber, fat, cholesterol, and sugar content on food packages. Results generally suggest that well-educated, female main meal planners are more likely to use various types of nutritional information than others. Main meal planners who place more importance on nutrition but less importance on taste and those who have a higher perception of the healthfulness of their diet are more likely to use nutritional information on packages than others. Household size, race, employment status, urbanization, region, age, and income are also significant factors.

description: Efforts to stabilized employment and output in the agricultural sector of Yugoslavia through monetization contributed to inflationary pressures. Granger causality tests suggested that increases in the rate of growth in the supply of money to subsidize state-owned agribusiness were insufficient to maintain purchases of wheat and corn, but did cause purchases of cattle and swine. This result may be explained by producers having more flexibility in grain marketing (i.e., storage options and private buyers) and the perishability issues related to livestock marketing. The policy to maintain employment through monetization is shown to have been ineffective.

description: Chronic wounds are a serious problem that could cause severe morbidity and even death. The ability of statins including rosuvastatin calcium (RVS) to enhance wound healing was well reported. However, RVS is poorly soluble and has low bioavailability. Thus, this study aimed to prepare and evaluate RVS-loaded nanocubics to enhance its skin performance. In addition, silver nanoparticles (AgNPs) exhibited potent antimicrobial activity, thus, the optimum RVS-loaded nanocubics was capped with AgNPs to evaluate its effect in wound management. Box–Behnken design was adopted to prepare RVS nanocubics. The design investigated the effect of lecithin, poloxamer 407 concentrations and hydration time on vesicle size, zeta potential (ZP), entrapment efficiency (EE%) and in vitro drug release%. Optimum formulation capped with AgNPs was incorporated into a gel base and examined for wound healing efficiency using different pharmacological tests in rats. Nanocubics have shown a mean diameter between 167.2 ± 7.8 and 408 ± 18.4 nm, ZP values ranging from −20.9 ± 1.9 to −53.5 ± 4 mV, EE% equivocated between 31.6 ± 1.4 and 94.4 ± 8.6 and drug release after 12 h between 17.9 ± 1.9 and 68.0 ± 4.0%. The histopathological studies and serum tumour necrosis factor alpha (TNF-α) and interleukin-1β (IL-1β) levels confirmed the greater efficacy of RVS nanocubics capped with AgNPs gel in wound healing when compared with gentamicin ointment. RVS-loaded nanocubic vesicles and AgNPs-loaded hydrogel could be considered as a promising platform to enhance the wound healing and tissue repair processes.

description: An ordered probit model is used to investigate the factors that determine post-choice satisfaction of southeastern U.S. dairy farmers with their milk handlers. The impact on farmer satisfaction of milk handler attributes, farm/farmer characteristics, and farm location is tested. Results support the hypothesis that mailbox price and the quality of service provided by milk handlers have a positive effect on satisfaction levels. Bargaining-operating cooperatives are negatively associated with farmer satisfaction when contrasted against independently owned milk handlers and bargaining-only cooperatives. Choice and the ability to switch milk handlers are also important determinants of farmer satisfaction.

description: This study presents a testing methodology to analyze potential price asymmetries among the farm, wholesale, and retail levels of the U.S. broiler industry. Lag length, direction of causality and power of the integrators in the industry have allowed the wholesale price to become the center, causal price in the market. Asymmetric price transmissions, however, are limited. While downward movements in the wholesale price are passed on more fully to growers than increases in the wholesale price, only consumers in the North Central region of the U.S. share a larger portion of wholesalers' price increases than price decreases.

description: The local government of Bangladesh shows all the characters of a colonial one since our country was under the British Raj for 190 years and under Pakistan for around 24 years. During the British and Pakistani periods, even after independence, several structural changes were made to the local government bodies under different regimes. Despite all those efforts, Bangladesh has been known to be among the most centralized countries in the world. Over the past decade, however, major efforts have been undertaken to strengthen the role and capacity of local government institutions (LGIs). Currently, LGIs in Bangladesh have separate systems for rural and urban areas which are guided by its own separate and operational framework. However, the way the legislations are enacted and executed, each tier and unit has become a water tight compartment. The interdependence and inter-organizational relationships are generally ignored. All these have hampered the comprehensive growth of local government. Moreover, despite the recent legal empowerment of LGIs, the bulk of public services continue to be managed directly by central line ministries and their local administrative offices without systematic involvement of the elected local government institutions. Hence, a conflicting scenario is created between the elected decentralized LGIs with the administrative decentralized bodies which affect the quality of public service delivery. This article attempts to analyze the local government system in Bangladesh, with the intent to identify whether the current local government system is constraining the performance of local governments.

description: Aqueous suspensions of bundles and individual single-wall carbon nanotubes were prepared with the help of surfactants. We study the changes in the Raman spectra of the suspensions with respect to powders, and of exfoliated tubes with respect to bundles. The radial breathing modes (RBM) upshift in suspensions because of the internal pressure of the liquid. By contrast, no shift is observed in the RBM spectra after exfoliation in the suspensions. However, we demonstrate a selectivity of the exfoliation process for tubes of small diameters.

description: This study provides an analysis of nonindustrial private forest (NIPF) landowners' participation in forestry assistance programs. A probit model was used for data collected from a random sample of 329 Indiana landowners. The analysis revealed that total land owned, commercial reasons for ownership, government sources of information, and membership in forestry organizations influenced NIPF landowners' program participation. Age, fear of loss of property rights, and duration since the first wooded tract was acquired also influenced program participation. Location of landowners' residence on their wooded land and landowners' knowledge of and willingness to participate in a conservation easement influenced the participation in cost-share programs.

description: The interactions of egg yolk phosphatidylcholine liposomes with F108 and F127 triblock copolymers, in the monomer state, were analyzed by isothermal titration calorimetry (ITC) at 37 °C. According to the results, the critical micelle concentration was determined to be 0.4 and 0.04 wt.% for F108 and F127, respectively, by surface tension at 37 °C. According to the results, liposomes/poloxamers were not favoured energetically, since endothermic interactions were observed. However, positive changes in entropy promoted a spontaneous process. F127 had a greater partition coefficient (51.97 ± 1.77 × 104), stronger affinity, than F108 (8.19 ± 0.37 × 104) towards the vesicle lipid bilayer due to its larger hydrophobic block. After the ITC experiments, an increased vesicle size (within about 1–3 nm average) by dynamic light scattering and the formation of bilayer discs by electron microscopy (EM) was observed at low copolymer concentrations (0.57 mol% of F108 and 1.01 mol% of F127). The EM and ITC results confirmed the intimate association of the copolymers with the membrane instead of being simply absorbed onto the bilayer surface. Our results indicate that the temperature of the system (37 °C), the copolymer concentration and hydrophobic chain length are important factors for the interaction of poloxamers with lipid bilayers and the stability of liposomes.
Lessons for Science Classrooms The Tracking Change – Lesson Plans for NWT and Alberta Secondary Science Classrooms are based on extensive research with Indigenous peoples and local communities in the Mackenzie River Basin through Tracking Change. This research is intended to strengthen the voices of subsistence fishers and Indigenous communities in governance, as well as to demonstrate how the rivers are socially, economically, culturally, and ecologically important to the place and people. It was important to local communities that the knowledge they shared as part of Tracking Change was passed on to young people. These inquiry-based lesson plans bring research findings to life for youth in junior high and high school. The lesson plans were created to both meet curriculum outcomes and to share interesting aspects of the research done by local communities within the students’ own region.

description: We discuss magnetic Schrodinger operators perturbed by measures from the generalized Kato class. Using an explicit Krein-like formula for their resolvent, we prove that these operators can be approximated in the strong resolvent sense by magnetic Schrodinger operators with point potentials. Since the spectral problem of the latter operators is solvable, one in fact gets an alternative way to calculate discrete spectra; we illustrate it by numerical calculations in the case when the potential is supported by a circle.

The asymptotic quasi-stationary states of the two-dimensional magnetically confined plasma and of the planetary atmosphere

description: We derive the differential equation governing the asymptotic quasi-stationary states of the two dimensional plasma immersed in a strong confining magnetic field and of the planetary atmosphere. These two systems are related by the property that there is an intrinsic constant length: the Larmor radius and respectively the Rossby radius and a condensate of the vorticity field in the unperturbed state related to the cyclotronic gyration and respectively to the Coriolis frequency. Although the closest physical model is the Charney-Hasegawa-Mima (CHM) equation, our model is more general and is related to the system consisting of a discrete set of point-like vortices interacting in plane by a short range potential. A field-theoretical formalism is developed for describing the continuous version of this system. The action functional can be written in the Bogomolnyi form (emphasizing the role of Self-Duality of the asymptotic states) but the minimum energy is no more topological and the asymptotic structures appear to be non-stationary, which is a major difference with respect to traditional topological vortex solutions. Versions of this field theory are discussed and we find arguments in favor of a particular form of the equation. We comment upon the significant difference between the CHM fluid/plasma and the Euler fluid and respectively the Abelian-Higgs vortex models.

First, household recreation demand functions are estimated based on the individual travel cost model using truncated count data regression methods and alternative price specifications. Findings show mean per trip consumer surplus point estimates between $89 and $286, depending on modeling assumptions and river quality. Magnitudes of these surpluses are very dependent on assumptions about the opportunity cost of time.

description: The field-angle dependent specific heat and thermal conductivity in the vortex phase of UPd_2Al_3 is studied using the Doppler shift approximation for the low energy quasiparticle excitations. We first give a concise presentation of the calculation procedure of magnetothermal properties with vortex and FS averages performed numerically. The comparison of calculated field-angle oscillations and the experimental results obtained previously leads to a strong reduction of the possible SC candidate states in UPd_2Al_3. The possible SC gap functions have node lines in hexagonal symmetry planes containing either the zone center or the AF zone boundary along c. Node lines in non-symmetry planes can be excluded. We also calculate the field and temperature dependence of field-angular oscillation amplitudes. We show that the observed nonmonotonic field dependence and sign reversal of the oscillation amplitude is due to small deviations from unitary scattering.

description: Using first-principles density functional calculations, we investigated work functions (WFs) of thin double-walled nanotubes (DWNTs) with outer tube diameters ranging from 1nm to 1.5nm. The results indicate that work function change within this diameter range can be up to 0.5 eV, even for DWNTs with same outer diameter. This is in contrast with single-walled nanotubes (SWNTs) which show negligible WF change for diameters larger than 1nm. We explain the WF change and related charge redistribution in DWNTs using charge equilibration model (CEM). The predicted work function variation of DWNTs indicates a potential difficulty in their nanoelectronic device applications.

Accurate estimation of fish stock biomass is crucial for ensuring sustainable exploitation of marine resources. Spatio-temporal models can provide improved indices of biomass as they capture spatial and temporal correlations in data and can account for environmental factors influencing biomass distributions. In this study, we developed a spatio-temporal generalized additive model (st-GAM) to investigate the relationships between bottom temperature, depth, and the biomass of three key fished species on The Grand Banks: snow crab (Chionoecetes opilio), yellowtail flounder (Limanda ferruginea), and Atlantic cod (Gadus morhua).

In particular, we devise a batch version of a model proposed originally by Berg et al. [Quant. Fin. 1 (2001) 203], and convert the coupled multi-agent processes into an effective-agent problem from which the dynamical order parameters in ergodic regimes can be derived self-consistently together with the corresponding phase structure. Our dynamical study complements and extends the available static theory. Results are confirmed by numerical simulations.

The simulation results strongly suggest that the more clustered the network, the poorer its synchronizability.

description: The Sloan Digital Sky Survey (SDSS) has proved to be a powerful resource for understanding the physical properties and chemical composition of star-forming galaxies in the local universe. The SDSS population of active galactic nuclei (AGN) remains as of yet less explored in this capacity. To extend the rigorous study of \ion{H}{ii} regions in the SDSS to AGN, we adapt methods for computing direct-method chemical abundances for application to the narrow-line regions (NLR) of AGN. By accounting for triply-ionized oxygen, we are able to more completely estimate the total oxygen abundance. We find a strong correlation between electron temperature and oxygen abundance due to collisional cooling by metals. Furthermore, we find that nitrogen and oxygen abundances in AGN are strongly correlated. From the metal-temperature relation and the coupling of nitrogen and oxygen abundances, we develop a new, empirically and physically motivated method for determining chemical abundances from the strong emission lines commonly employed in flux-ratio diagnostic diagrams (BPT diagrams). Our approach, which for AGN reduces to a single equation based on the BPT line ratios, consistently recovers direct-method abundances over a 1.5 dex range in oxygen abundance with an rms uncertainty of 0.18 dex. We have determined metallicities for thousands of AGN in the SDSS, and in the process have discovered an ionization-related discriminator for Seyfert and LINER galaxies.

description: A relation between $\frac{1}{2}$-derivations of Lie algebras and transposed Poisson algebras was established. Some non-trivial transposed Poisson algebras with a certain Lie algebra (Witt algebra, algebra $\mathcal{W}(a,-1)$, thin Lie algebra and solvable Lie algebra with abelian nilpotent radical) were constructed. In particular, we constructed an example of the transposed Poisson algebra with associative and Lie parts isomorphic to the Laurent polynomials and the Witt algebra. On the other side, it was proven that there are no non-trivial transposed Poisson algebras with Lie algebra part isomorphic to a semisimple finite-dimensional algebra, a simple finite-dimensional superalgebra, the Virasoro algebra, $N=1$ and $N=2$ superconformal algebras, or a semisimple finite-dimensional $n$-Lie algebra.

description: A new discontinuous Galerkin finite element method for the Stokes equations is developed in the primary velocity-pressure formulation. This method employs discontinuous polynomials for both velocity and pressure on general polygonal/polyhedral meshes. Most finite element methods with discontinuous approximation have one or more stabilizing terms for velocity and for pressure to guarantee stability and convergence. This new finite element method has the standard conforming finite element formulation, without any velocity or pressure stabilizers. Optimal-order error estimates are established for the corresponding numerical approximation in various norms. The numerical examples are tested for low and high order elements up to the degree four in 2D and 3D spaces.

description: We present a multi-wavelength study of the active galactic nucleus in the nearby ($D=14.1$ Mpc) low mass galaxy IC 750, which has circumnuclear 22 GHz water maser emission. The masers trace a nearly edge-on, warped disk $\sim$0.2 pc in diameter, coincident with the compact nuclear X-ray source which lies at the base of the $\sim$kpc-scale extended X-ray emission. The position-velocity structure of the maser emission indicates the central black hole (BH) has a mass less than $1.4 \times 10^5~M_\odot$. Keplerian rotation curves fitted to these data yield enclosed masses between $4.1 \times 10^4~M_\odot$ and $1.4 \times 10^5~M_\odot$, with a mode of $7.2 \times 10^4~M_\odot$. Fitting the optical spectrum, we measure a nuclear stellar velocity dispersion $σ_* = 110.7^{+12.1}_{-13.4}$~{\rm km~s}$^{-1}.$ From near-infrared photometry, we fit a bulge mass of $(7.3 \pm 2.7) \times 10^8~M_\odot$ and a stellar mass of $1.4 \times 10^{10}~M_\odot$. The mass upper limit of the intermediate mass black hole in IC 750 falls roughly two orders of magnitude below the $M_{\rm BH}-σ_*$ relation and roughly one order of magnitude below the $M_{\rm BH}-M_{\rm Bulge}$ and $M_{\rm BH}-M_*$ relations -- larger than the relations' intrinsic scatters of (0.58 $\pm$ 0.09) dex, 0.69 dex, and (0.65 $\pm$ 0.09) dex, respectively. These offsets could be due to larger scatter at the low mass end of these relations. Alternatively, black hole growth is intrinsically inefficient in galaxies with low bulge and/or stellar masses, which causes the black holes to be under-massive relative to their hosts, as predicted by some galaxy evolution simulations.

description: The rise of populism and nationalism has recently become highly observable. It has caused systemic changes in political, social and economic fields. Populist and nationalist political movements achieve varying success around the world. Populist and nationalist discourses, such as anti-immigration and anti-multiculturalism, intensify. Besides, conspiratorial thinking has become prevalent. The rise of populism and nationalism also shows its implications throughout the COVID-19 pandemic. There has been a populist resistance against mask wearing and social distancing. Moreover, several conspiracy theories have been prevalent. Finally, xenophobic and racist incidents take place, and orientalist rhetoric against Asian communities resurfaces.This thesis aims to reach conclusions that will provide a better understanding of the impact of rising populism and nationalism on COVID-19 pandemic with the help of social constructivism. As an idealist theory, social constructivism is convenient for understanding populism and nationalism, identity-related phenomena.
Multipole Fluctuations in Filled Skutterudites

description: In order to clarify exotic multipole properties of filled skutterudites, we evaluate multipole susceptibility for $n$=1$\sim$5, where $n$ is the local $f$-electron number, on the basis of a multiorbital Anderson model constructed using the $j$-$j$ coupling scheme. For $n$=1, magnetic fluctuations dominate over low-temperature electronic properties, while for $n$=2 and 4, electronic states are dominated by both magnetic and quadrupole fluctuations. For $n$=3 and 5, octupole fluctuations are found to be significant, depending on the crystalline electric field potential. We discuss possible relevance of the results to actual materials.

description: A master action for the bosonic p-brane, interpolating between the Nambu--Goto and Polyakov formalisms, is discussed. The fundamental arbitrariness of extended structures (p-brane) embeded in space time manifold has been exploited to build an independent metric in the brane world volume. The cosmological term for the generic case follows naturally in the scheme. The dynamics of the structure leads to a natural emergence of the A--D--M like split of this world volume. The role of the gauge symmetries vis-à-vis reparametrization symmetries is analyzed by a constrained Hamiltonian approach.

description: Understanding and classifying nonequilibrium many-body phenomena, analogous to the classification of equilibrium states of matter into universality classes, is an outstanding problem in physics. Any many-body system, from stellar matter to financial markets, can be out of equilibrium in a myriad of ways; since many are also difficult to experiment on, it is a major goal to establish universal principles that apply to different phenomena and physical systems. At the heart of the classification of equilibrium states is the universality seen in the self-similar spatial scaling of systems close to phase transitions. Recent theoretical work, and first experimental evidence, suggest that isolated many-body systems far from equilibrium generically exhibit dynamic (spatiotemporal) self-similar scaling, akin to turbulent cascades and the Family-Vicsek scaling in classical surface growth. Here we observe bidirectional dynamic scaling in an isolated quench-cooled atomic Bose gas; as the gas thermalises and undergoes Bose-Einstein condensation, it shows self-similar net flows of particles towards the infrared (smaller momenta) and energy towards the ultraviolet (smaller lengthscales). For both infrared (IR) and ultraviolet (UV) dynamics we find that the scaling exponents are independent of the strength of the interparticle interactions that drive the thermalisation.

description: We consider hydrodynamics of N=4 supersymmetric SU(N_c) Yang-Mills plasma at a nonzero density of R-charge. In the regime of large N_c and large 't Hooft coupling the gravity dual description involves an asymptotically Anti- de Sitter five-dimensional charged black hole solution of Behrnd, Cvetic and Sabra. We compute the shear viscosity as a function of chemical potentials conjugated to the three U(1) \subset SO(6)_R charges. The ratio of the shear viscosity to entropy density is independent of the chemical potentials and is equal to 1/4π. For a single charge black hole we also compute the thermal conductivity, and investigate the critical behavior of the transport coefficients near the boundary of thermodynamic stability.

description: The classification problem is a significant topic in machine learning which aims to teach machines how to group together data by particular criteria. In this paper, a framework for the ensemble learning (EL) method based on group decision making (GDM) has been proposed to resolve this issue. In this framework, base learners can be considered as decision-makers, different categories can be seen as alternatives, classification results obtained by diverse base learners can be considered as performance ratings, and the precision, recall, and accuracy which can reflect the performances of the classification methods can be employed to identify the weights of decision-makers in GDM. Moreover, considering that the precision and recall defined in binary classification problems can not be used directly in the multi-classification problem, the One vs Rest (OvR) has been proposed to obtain the precision and recall of the base learner for each category. The experimental results demonstrate that the proposed EL method based on GDM has higher accuracy than other 6 current popular classification methods in most instances, which verifies the effectiveness of the proposed method.

Hedonic approaches to measuring price and quality change in personal computer systems
Creators: name: Chwelos, Paul
Publisher: name: University of British Columbia
Year: 2009

description: Although computers have long been studied in terms of their changing price/performance ratio, the issue of accounting for performance in computer systems has not been adequately addressed. This paper addresses the topic in three ways. First, a survey of IS Managers and business "power-users" of personal computers was conducted to empirically determine the attributes of computer systems that provide value to users; these results guide subsequent choices regarding the operationalisation of user value. Second, an index of system performance was developed from published performance benchmarks and used as a direct measure of performance in the hedonic function. Third, a set of technical proxies was shown to adequately reproduce the performance index derived above, and was used in an alternate specification of the hedonic function. Using data on IBM-PC compatible laptop and desktop systems, price indexes were constructed using both approaches to performance measurement. The results demonstrated that both approaches yielded good explanatory power and nearly identical estimates of the rate of quality adjusted price change in PC systems. Thus, the set of technical proxies could be used to operationalise performance in a larger data set for which direct performance measures are unavailable. For the 1990s, laptop PCs were found to have decreased in quality adjusted price at an average of 39% per year while the corresponding figure for desktop PCs was 35% per year.
