description: If the lepton mixing angle theta_{23} is not maximal, there arises a problem of ambiguity in determining theta_{23} due to the existence of two degenerate solutions, one in the first and the other in the second octant. We discuss an experimental strategy for resolving the theta_{23} octant degeneracy by combining reactor measurement of theta_{13} with accelerator nu_{mu} disappearance and nu_{e} appearance experiments. The robustness of the theta_{23} degeneracy and the difficulty in lifting it only by accelerator experiments with conventional nu_{mu} (and nu_{mu}-bar) beam are demonstrated by analytical and numerical treatments. Our method offers a way to overcome the difficulty and can resolve the degeneracy between solutions sin^2 theta_{23} = 0.4 and sin^2 theta_{23} = 0.6 if sin^2 (2 theta_{13}) \gsim 0.05 at 95% CL by assuming the T2K phase II experiment and a reactor measurement with an exposure of 10 GW.kt.yr. The dependence of the resolving power of the octant degeneracy on the systematic errors of reactor experiments is also examined.

description: We provide an algorithm to test the law of aggregate demand with runtime complexity polynomial to the length of the agent’s preference relation over a set of contracts. Access to this preference relation is essential, as we show that any algorithms with only oracle access to the agent’s choice function require a number of queries exponential to the number of contracts.

description: Type I string theory in the presence of internal magnetic fields provides a concrete realization of split supersymmetry. To lowest order, gauginos are massless while squarks and sleptons are superheavy. For weak magnetic fields, the correct Standard Model spectrum guarantees gauge coupling unification with \sin^2{θ_W}=3/8 at the compactification scale of M_{\rm GUT}\simeq 2 \times 10^{16} GeV. I discuss mechanisms for generating gaugino and higgsino masses at the TeV scale, as well as generalizations to models with split extended supersymmetry in the gauge sector.

description: This paper aims to provide a descriptive analysis of the micro-market, Yele, Sierra Leone, pre-electrification. It will do so through descriptive statistics and visual representations with the intention of providing recommendations to ensure the success of market growth post-electrification. My original work aimed to provide an analysis both before and after electrification. However, due to political unrest and lack of capital the hydroelectric power plant is still not live at the time of this paper. To start, I will introduce my previous work in Yele and the hydroelectric power plant that the Lion Heart Foundation is building. Then I will discuss descriptive statistics which include, returns to education, business sector make up, and capital measures. I provide visual representations of these various dynamics and give my policy recommendations for when electricity goes live. In general, my concerns are the location and regulation of those with lower education levels. I offer two predictions on what will happen to the shops in the service sector. First, I believe there will be an expansion of those businesses in the service sector. This will be followed by a consolidation of shops that are of the same nature. Lastly, I present my intentions for future studies in product diversification. I predict that product diversification will follow as similar patter to the shops in the service sector.

description: The widespread adoption of wearable fitness trackers in recent years has resulted in a substantial increase in the daily collection of personal data beyond just usage and functionality. This data facilitates critical analyses that improve service offerings, monitor user behavior, optimize products, and provide recommendations. However, these advantages must be weighed against rising concerns about privacy preservation. Differential Privacy (DP) provides a solution to this potential conflict between the desire to protect privacy and the need to conduct data analyses. DP aims to enable comprehensive data analyses on a population while maintaining a mathematically precise definition of privacy for individuals. In this research, Differential Privacy (DP) mechanisms were applied to wearable device datasets, particularly focusing on maintaining data utility while ensuring privacy. The study evaluated the Laplace, Gaussian, and Exponential mechanisms, finding that the Laplace and Gaussian mechanisms effectively preserved the dataset’s integrity with minimal deviations, whereas the Exponential mechanism caused more significant variations. The parametric analysis of varying privacy budget values (ϵ) showed that smaller ϵ values resulted in larger deviations, while larger ϵ values maintained more data accuracy. Additionally, sensitivity parameter variations demonstrated that higher sensitivity values introduced more noise but kept data within a reasonable range, highlighting the importance of choosing appropriate parameters for balancing privacy and data utility. This thesis also aims to provide an understandable introduction of Privacy Preserving Techniques (PETs) with its implications and importance in Wearable Fitness Trackers. It also discusses inferences from Wearable Fitness Trackers. It furthermore discusses about the related work in Privacy Preserving and data breach mitigation strategies as Well. Mostly this work focuses on Differential Privacy and its mechanisms. The DP mechanisms are implemented for both Global and Local DP frameworks. At the end the a detailed analysis of these mechanism is conducted with all the parameters variations. The results then defines the trade-off between privacy and utility of data. Finally non-technical privacy preserving options are discussed such as Data Privacy Governance, Ethics etc. and the application of DP in real world scenarios.

description: Through data analysis, we present new sets of nonperturbative fragmentation functions (FFs) for $Λ_c^+$ baryon both at leading and next-to-leading order (NLO) and, for the first time, at next-to-next-to-leading order (NNLO) in the minimal subtraction factorization scheme with five massless quarks. The FFs are determined by fitting all available data of inclusive single $Λ_c^+$ baryon production in $e^+e^-$ annihilation taken by the OPAL Collaboration at CERN LEP1 and Belle Collaboration at KEKB. We also estimate the uncertainties in the $Λ_c^+$ FFs as well as in the corresponding observables. In a completely different approach based on the Suzuki model, we will theoretically calculate the $Λ_c^+$ FF from charm quark and present our result at leading order perturbative QCD framework. A comparison confirms a good consistency between both approaches. We will also apply the $Λ_c^+$ FFs to make theoretical predictions for the energy distribution of $Λ_c^+$ produced through the top quark decay, to be measured at the CERN LHC.

description: This report is in response to a national and state interest in the potential benefits of industrial hemp as an alternative crop. Industrial hemp has many uses which can be categorized into nine submarkets. North Dakota may have a comparative advantage in producing industrial hemp seed for oil because of the multi-oil processing facility in Carrington (AgGrow Oils) and the established infrastructure. Industrial hemp is currently legally produced in 22 countries with Canada being the closest and is recognized as a legal and legitimate crop in both the NAFTA and GATT agreements. The main obstacles for legalization of industrial hemp appear to be 1) law enforcement officials are concerned about the regulation, 2) no domestic facilities currently exist to process hemp stalks, although Canada will have such facilities shortly, 3) there is a lack of current production and processing technology, and 4) lack of research on the production potential and quality aspects of the crop. Since very little is known about the potential yield and quality of industrial hemp fiber and seed that would be produced in North Dakota, it is recommended that controlled experimental production and processing be allowed. Necessary baseline production, processing, and marketing data could be collected and analyzed, and law enforcement concerns could also be addressed.

description: We report near-infrared integral field spectroscopic observations of the active galactic nucleus NGC 4151 with archive data from the NIFS-Gemini North Telescope. We have selected best-seeing observations ($\lesssim$0.3 arcsec) that, allied to our methodology of image processing techniques, show structures with spatial resolution comparable to those of the HST. The intricate outflow of NGC 4151 is revisited in light of the results found for NGC 1068, in a previous work, and a very similar dynamic is found: the low-velocity [Fe II] emission depicts the glowing walls of an hourglass structure, while the high-velocity gas fills its volume. From this finding, we show that the misalignment between the jet and the NLR is not a projection effect, as previously thought. A molecular outflow is detected for the first time in this galaxy and, just like in NGC 1068, the transition between the molecular and the ionized gas phases comes from the fragmentation of molecular cavity walls into bullets of ionized gas exposed to the central source. Furthermore, it is suggestive that the same geometrical dichotomy between the cones seen in NGC 1068 is found here, with one side, where the cavity is disrupted by the AGN, being more extended than the other. Finally, a new spatial correlation between the high-velocity [Fe II] and the soft X-ray emission of [Ne IX] is found, which is unexpected given the difference between their ionization potentials.

Formation and evolution of late-type dwarf galaxies. I. NGC 1705 and NGC 1569

description: (Abridged.) We present one-zone chemical evolution models for two dwarf starburst galaxies, NGC 1705 and NGC 1569. Using information about the past star formation history and initial mass function of the systems previously obtained from Hubble Space Telescope colour-magnitude diagrams, we identify possible scenarios of chemical enrichment and development of galactic winds. In order not to overestimate the current metallicity of the interstellar gas inferred from H II region spectroscopy, we suggest that the winds efficiently remove from the galaxies the metal-rich ejecta of dying stars. Conversely, requiring the final mass of neutral gas to match the value inferred from 21-cm observations implies a relatively low efficiency of interstellar medium entrainment in the outflow, thus confirming previous findings that the winds driving the evolution of typical starbursts are differential. These conclusions could be different only if the galaxies accrete huge fractions of unprocessed gas at late times. By assuming standard stellar yields we obtain a good fit to the observed nitrogen to oxygen ratio of NGC 1569, while the mean N/O ratio in NGC 1705 is overestimated by the models. Reducing the extent of hot bottom burning in low-metallicity intermediate-mass stars does not suffice to solve the problem. Localized self-pollution from stars more massive than 60 MSun in NGC 1705 and/or funneling of larger fractions of nitrogen through its winds are then left to explain the discrepancy between model predictions and observations. Inspection of the log(N/O) vs. log(O/H)+12 diagram for a sample of dwarf irregular and blue compact dwarf galaxies in the literature favours the latter hypothesis.

description: Regulations relating to disease management have traditionally been an important component of the overall environment in which international trade in agriculture products occurs. The World Trade Organization (WTO) Agreement on the Application of Sanitary and Phytosanitary Measures (SPS Agreement) allows members to restrict or prohibit imports from a country when imported products present a risk to human, animal or plant health or life. As the Bovine Spongiform Encephalopathy (BSE, also commonly called Mad Cow disease in the media) outbreak in Canada showed, the disease status of a country is a major competitive advantage and losing disease-free status can impose significant costs on an industry. The risks associated with SPS-based border closures were not well anticipated by the Canadian industry and government, and little was done in preparation for the potential change in the trading environment and the ensuing losses. This is a mistake many stakeholders in the industry plan to avoid making again.

description: The d-vector in possibile spin triplet superconductor Na_{x}CoO_{2}yH_{2}O is microscopically investigated on the basis of the multi-orbital Hubbard model including the atomic spin-orbit coupling. As a result of the perturbation theory, we obtain the stable spin triplet superconductivity where the p-wave and f-wave states can be stabilized. If we neglect the spin-orbit coupling, superconducting state has 6-fold (3-fold) degeneracy in the p-wave (f-wave) state. This degeneracy is lifted by the spin-orbit coupling. We determine the d-vector within the linearlized Dyson-Gorkov equation. It is shown that the d-vector is always along the plane when the pairing symmetry is p-wave, while it depends on the parameters in case of the f-wave state. The lifting of degeneracy is significant in the p-wave state while it is very small in the f-wave state. This is because the first order term with respect to the spin-orbit coupling is effective in the former case, while it is ineffective in the latter case. The consistency of these results with NMR and \muSR measurements are discussed.

Determinants of ASP success
Creators: name: MacKenzie, Winston Joseph
Publisher: name: University of British Columbia
Year: 2009

description: Application Service Providers (ASP) are a recent phenomenon in the sphere of information technology. Leveraging the advantages of the universally accessible and ubiquitous nature of the Internet, application service providers claim to lower the cost of ownership of applications. Generally operating from a central and remote data centre, ASPs 'rent' their applications to clients in a 'pay as you go' fashion. This has several advantages to the client besides cost savings. This thesis introduces the reader to ASPs and examines the reasons companies hire the services of an ASP; furthermore it suggests an analytic framework based upon economic concepts in an attempt to predict what business models and strategies will be successful in the ASP market and what shape that market might take. The thesis also discusses the possible effect of some emerging technologies.

description: We discuss recent bilateral, regional, and country trade, partnership, and economic agreements involving both ASEAN as a single entity and individual ASEAN countries (Singapore, Thailand, Malaysia) focusing on their reach beyond conventional trade in goods and services issues. These agreements are recent, but they are numerous and more are under negotiation. We separately synthesize and evaluate provisions in five areas; competition policy, investment, mutual recognition, movement of persons, and broader cooperation. What emerges is of a picture of ill defined general commitments and precise undertaking, which vary from element to element and country pair to country pair, but there can be little doubt as to the presence of substance, which in turn, seemingly grows in complexity and form in more recent agreements.

description: We resolve the inner region of a massive cluster forming in a cosmological LCDM simulation with a mass resolution of 2*10^6 Msun and before z=4.4 even 3*10^5 Msun. This is a billion times less than the clusters final virial mass and a substantial increase over current LCDM simulations. We achieve this resolution using a new multi-mass refinement procedure and are now able to probe a dark matter halo density profile down to 0.1 percent of the virial radius. The inner density profile of this cluster halo is well fitted by a power-law rho ~ r^-gamma down to the smallest resolved scale. An inner region with roughly constant logarithmic slope is now resolved, which suggests that cuspy profiles describe the inner profile better than recently proposed profiles with a core. The cluster studied here is one out of a sample of six high resolution cluster simulations of Diemand et al. (2004) and it's inner slope of gamma = 1.2 lies close to the sample average.

description: The recently developed hadron resonance gas model with multicomponent hard-core repulsion is used to address and resolve the long standing problem to describe the light nuclear cluster multiplicities including the hyper-triton measured by the STAR Collaboration, known as the hyper-triton chemical freeze-out puzzle. An unprecedentedly accurate description is obtained for the hadronic and other light nuclear cluster data measured by STAR at the collision energy $\sqrt{s_{NN}} =200$ GeV and by ALICE at $\sqrt{s_{NN}} =2.76$ TeV. This success is achieved by applying the new strategy of analyzing the light nuclear cluster data and by using the value for the hard-core radius of the (anti-)$Λ$ hyperons found in earlier work. One of the most striking results of the present work is that for the most probable scenario of chemical freeze-out for the STAR energy the obtained parameters allow to simultaneously reproduce the values of the experimental ratios $S_3$ and $\bar{S}_3$ which were not included in the fit.

description: Through this research, I have looked at the relationship between the unemployment rate and the birth rate with a focus in Korea. For past few decades, despite the high volume of students obtaining undergraduate degrees, the unemployment rate has constantly increased, bringing about a critical social issue. On the other hand, families have been giving birth to fewer children or no child at all despite the government’s efforts to financially aid parents to raise their children. Because of this phenomenon, a new term called ‘Sampo generation’ has emerged, describing people in their 20s and 30s giving up on three things since they can’t economically support themselves: dating, marriage, and giving birth. It has been discovered that the unemployment rate has negative correlation with the birth rate although the labor participation rate has a stronger relationship with the fertility rate. With larger unemployment, the birth rate is decreased whereas with larger participation rate, the number of babies born is increased. Also, interestingly, the effect of unemployment and education are often the opposite for females and males. As people earn more money, however, they postpone their chances of having a child or more although its negative correlation is explained away by education. Lastly, Conservatives have more children than Democrats and Independents and considering the historical and cultural differences between regions, the political affiliations were regarded as proxies for indicating regions that have higher or lower birth rates. However, it has been found that whether the region is relatively urban or rural is a stronger factor determining the birth rates than the political perspectives.

description: We have studied the transport properties of a molecular device composed of donor and acceptor moieties between two electrodes on either side. The device is considered to be one-dimensional with different on-site energies and the non-equilibrium properties are calculated using Landauer's formalism. The current-voltage characteristics is found to be asymmetric with a sharp Negative Differential Resistance at a critical bias on one side and very small current on the other side. The NDR arises primarily due to the bias driven electronic structure change from one kind of insulating phase to another through a highly delocalized conducting phase. Our model can be considered to be the simplest to explain the experimental current-voltage characteristics observed in many molecular devices.

description: Researchers assembled a database of current and projected information on the following: welfare recipients; other female participants in the labor market; employment, occupational availability, and job openings; and occupational characteristics. The database was used in a multistep process to project the number of women forced to leave welfare rolls between statewide implementation of Texas' time limits and the year 2000 and other key figures. Findings revealed the following: over 59,000 women are expected to be forced to leave Texas' welfare rolls; more than half will have worked within the previous 2 years with average wages of less than $3,700; three-quarters will have been "long-term" recipients; most forced exiters are expected to be black women; and women entering the labor market from the welfare rolls will increase the statewide labor force by less than two-thirds of 1 percent. The greatest share of jobs available to forced exiters would be in service occupations. About two of five available jobs would be full time/full year. Fewer than 30 percent of all potential jobs would enable a family of three to escape poverty. At least 50 percent of possible employment opportunities would lack medical insurance coverage, dental coverage, paid personal leave, and sick leave. Well over half of all available jobs would tend to be unstable. Nearly all Texas regions were expected to have ample numbers of jobs for forced exiters in female-dominated occupations.

description: This work investigates at what degree two neuromorphometric measurements, namely the autocorrelation and the excluded volume of a neuronal cell can influence the characterization and classification of such a type of cells. While the autocorrelation function presents good potential for quantifying the dendrite-dendrite connectivity of cells in mosaic tilings, the excluded volume, i.e. the amount of the surround space which is geometrically not accessible to an axon or dendrite, provides a complementary characterization of the cell connectivity. The potential of such approaches is illustrated with respect to real neuronal cells.

description: Using a static, multi-market, partial equilibrium model this paper assesses the economic consequences three alternative government responses to the BSE crisis in Canada: 1) expansion in slaughter capacity, 2) partial destruction of the cattle herd, and 3) deficiency payments. Each of these policies is evaluated under four different border situations 1) free trade in young beef only, the 2004 baseline situation; 2) autarky; 3) free trade in young beef and cattle; and 4) complete free trade. The results of the policy analysis are quite sensitive to the border assumptions employed making it impossible to select a "best" policy without perfect foresight with respect to the timing and the degree of border opening.

description: The paper evaluates the effect of regulation on the number of households living in informal settlements. Initially, a profile of the regulatory climate and urban informal settlements in Nigeria is presented using Lagos State as an example. Subsequently, econometric analysis is carried out using the MIMIC model to estimate the impact of determinants and the size of the informal sector in each area. Given the results of the analysis, it is argued that since households are mobile within the country, an increase in regulation and enforcement in a region decreases the size of informality in that region. However, informality in regions with less regulation is higher.

Agreements are in place with Hong Kong, Macao, ASEAN, Australia, and New Zealand, and are either in negotiation or under discussion with South Africa, Chile, India, and the Gulf Cooperation Council. These agreements differ sharply in form and substance, and involve process commitments to ongoing negotiation and cooperation on a wide range of issues. Differences relating to the regional agreements negotiated by the EU and the US are emphasized, as are later potential difficulties these agreements create in moving to an Asian trade bloc centred on them.

This study examines the economy-wide impacts of various policy packages on rice and related markets, which consist of liberal as well as protectionist elements. A general equilibrium model developed for the Sri Lankan economy using the input-output table for 2000 was used for the analysis. The model consists of 5 sectors, 2 factors of production and households in 8 representative provinces. The key results of the analysis indicate that removal of the import tariff on rice along with removals of the import tariff on fertilizer and/or subsidy payments on other agricultural sectors could improve economic efficiency and household welfare across provinces. Contrary to the general belief that protectionism is pro-poor, an import ban on rice reduces household income and welfare even in agricultural provinces, including Uva and Sabaragamuwa. Further analysis indicates that broad-brush approaches may not yield expected outcomes, as the policy packages generate second best outcomes due to existence of other distortions in the economy. The key channel of transmission of trade shock to households appears to be through government transfer payments that are influenced by changes in government expenditures on subsidy payments.
How Service-oriented High Performance Work Systems shape hotel employees' performance outcomes: A study through employees' lens
Creators: name: Pham, Huy Thong

description: The tourism and hospitality sector in Vietnam faces challenges due to rising customer demands and competition. This research examines how service-oriented high performance work systems (SHPWSs) can improve customer service and gain a competitive edge. The study found that SHPWSs promote proactive customer service performance and service recovery performance among front-line workers. The study also enriches the stream of SHPWSs research by unveiling both contextual (i.e., HRM system strength) and individual (i.e., proactive personality) boundary conditions for the effects of SHPWSs. The findings can help hospitality managers formulate effective strategies to promote specific employee service performances.

description: We present a theory of current conduction through buckyball(C60) molecules on silicon by coupling a density functional treatment of the molecular levels embedded in silicon with a non-equilibrium Green's function (NEGF) treatment of quantum transport. Several experimental variations in conductance-voltage(G-V) characteristics are quantitatively accounted for by varying the detailed molecule-silicon bonding geometries. We identify how variations in contact surface microstructure influence the number, positions and shapes of the conductance peaks, while varying separations of the scanning probe from the molecules influence their peak amplitudes.

description: We present a novel multiscale simulation approach for modeling stochasticity in chemical reaction networks. The approach seamlessly integrates exact-stochastic and "leaping" methodologies into a single "partitioned leaping" algorithmic framework. The technique correctly accounts for stochastic noise at significantly reduced computational cost, requires the definition of only three model-independent parameters and is particularly well-suited for simulating systems containing widely disparate species populations. We present the theoretical foundations of partitioned leaping, discuss various options for its practical implementation and demonstrate the utility of the method via illustrative examples.

description: The WTO Framework Agreement negotiators accepted in July 2004 provides a guide to the commitments a Doha Development Agenda agreement may contain. These commitments will involve direct and indirect export subsidies, domestic support and market access. Commitments in each of these areas will have implications for Canadian agriculture. This paper explores these implications for supply management, the Canadian Wheat Board and domestic support programs.

description: Following recent work on heavy-light correlators in higher-dimensional conformal field theories (CFTs) with a large central charge $C_T$, we clarify the properties of stress tensor composite primary operators of minimal twist, $[T^m]$, using arguments in both CFT and gravity. We provide an efficient proof that the three-point coupling $\langle \mathcal{O}_L\mathcal{O}_L [T^m]\rangle$, where $\mathcal{O}_L$ is any light primary operator, is independent of the purely gravitational action. Next, we consider corrections to this coupling due to additional interactions in AdS effective field theory and the corresponding dual CFT. When the CFT contains a non-zero three-point coupling $\langle TT \mathcal{O}_L\rangle$, the three-point coupling $\langle \mathcal{O}_L\mathcal{O}_L [T^2]\rangle$ is modified at large $C_T$ if $\langle TT\mathcal{O}_L \rangle \sim \sqrt{C_T}$. This scaling is obeyed by the dilaton, by Kaluza-Klein modes of prototypical supergravity compactifications, and by scalars in stress tensor multiplets of supersymmetric CFTs. Quartic derivative interactions involving the graviton and the light probe field dual to $\mathcal{O}_L$ can also modify the minimal-twist couplings; these local interactions may be generated by integrating out a spin-$\ell \geq 2$ bulk field at tree level, or any spin $\ell$ at loop level. These results show how the minimal-twist OPE coefficients can depend on the higher-spin gap scale, even perturbatively.

description: A special safeguard mechanism is an attractive policy tool for low income importing countries because it is automatic and does not require an injury test. Exporters might accept a safeguard for low income countries if it results in larger tariff cuts than in its absence. Using wheat as a case study the effects of a special safeguard mechanism on market stability and welfare are evaluated. The results show that a safeguard mechanism is not very trade distorting and costs less than 20 percent of the world welfare gain that would be realized if developing countries were not granted a safeguard.

Electric Charge Quantization in SU(3)_C X SU(3)_L X U(1)_X Models

description: Basing on the general photon eigenstate and the anomaly cancelation, we have naturally explained the electric charge quantization in two models based on the SU(3)_C X SU(3)_L X U(1)_X gauge group, namely in the minimal model and in the model with right-handed neutrinos. In addition, we have shown that the electric charges of the proton and of the electron are opposite; and the same happens with the neutron and the neutrino. We argue that the electric charge quantization is not dependent on the classical constraints on generating mass to the fermions, but it is related closely with the generation number problem. In fact, both problems are properly solved as the direct consequences of the fermion content under the anomaly free conditions.

description: For two decades agriculture has been the lynchpin of every meeting of the world's trade ministers. The Hong Kong ministerial conference of the World Trade Organization (WTO) in December 2005 was no different. Once again, a multilateral trade round is blocked by failure to agree on reform of farm trade, a traditional sector representing less than 10% of world merchandise trade. But the current round differs from earlier rounds: a number of new political coalitions have formed, unformed and reformed, and the role of Canada seems obscure. The usual approaches to explaining international economic outcomes consider political economy factors. In this paper I ask if institutional factors are part of the problem, or the solution.

description: The contact values $g(σ,σ')$ of the radial distribution functions of a fluid of (additive) hard spheres with a given size distribution $f(σ)$ are considered. A ``universality'' assumption is introduced, according to which, at a given packing fraction $η$, $g(σ,σ')=G(z(σ,σ'))$, where $G$ is a common function independent of the number of components (either finite or infinite) and $z(σ,σ')=[2 σσ'/(σ+σ')]μ_2/μ_3$ is a dimensionless parameter, $μ_n$ being the $n$-th moment of the diameter distribution. A cubic form proposal for the $z$-dependence of $G$ is made and known exact consistency conditions for the point particle and equal size limits, as well as between two different routes to compute the pressure of the system in the presence of a hard wall, are used to express $G(z)$ in terms of the radial distribution at contact of the one-component system. For polydisperse systems we compare the contact values of the wall-particle correlation function and the compressibility factor with those obtained from recent Monte Carlo simulations.
