description: We study a classical reparametrization-invariant system, in which ``time'' is not a priori defined. It consists of a nonrelativistic particle moving in five dimensions, two of which are compactified to form a torus. There, assuming a suitable potential, the internal motion is ergodic or more strongly irregular. We consider quasi-local observables which measure the system's ``change'' in a coarse-grained way. Based on this, we construct a statistical timelike parameter, particularly with the help of maximum entropy method and Fisher-Rao information metric. The emergent reparametrization-invariant ``time'' does not run smoothly but is simply related to the proper time on the average. For sufficiently low energy, the external motion is then described by a unitary quantum mechanical evolution in accordance with the Schrödinger equation.

Narrowing Down XML Template Expansion and Schema Validation

description: This work examines how much template instantiation can narrow down schema validation for XML-documents. First, instantiation and validation are formalised. Properties towards their practical meaning are probed, an implementation is developed. Requirements for an unification are elaborated and a comparison is taken out. The semantics are formulated in terms of denotational semantics as well as rule-based referring to the data models chosen. Formalisation makes it clearer instantiation is adequately represented. Both semantics show, that the rules set for both, instantiation and validation, cannot totally be unified. However, reuse of simplified code also simplifies unification. Implementation allows unification of both processes on document-level. The validity of all implementations is guaranteed by a comprehensive test suite. Analysis shows the minimal XML template language has got regular grammar properties, except macros. An explanation was given, why filters and arrows are not best, especially towards a unified language to be variable and extensive. Recommendations for future language design are provided. Instantiation shows a universal gap in applications, for instance, as seen by XSLT. Lack of expressibility of arbitrary functions in a schema is one such example, expressibility of the command language is another basic restriction. Useful unification constraints are found out to be handy, such as typing each slot. In order to obtain most flexibility out of command languages adaptations are required. An alternative to introducing constraints is the effective construction of special NFAs. Comparison criteria are introduced regarding mainly syntax and semantics. Comparisons is done accordingly. Despite its huge syntax definitions XSD was found weaker than RelaxNG or XML template language. As template language the latter is considered universal.

description: Let $(\mathcal{M}, Q)$ be a dg manifold. The space of vector fields with shifted degrees $(\mathcal{X}(\mathcal{M})[-1], L_Q)$ is a Lie algebra object in the homology category $\mathrm{H}((C^{\infty}_{\mathcal{M}},Q)\mathrm{-}\mathbf{mod})$ of dg modules over $(\mathcal{M},Q)$, the Atiyah class $α_{\mathcal{M}}$ being its Lie bracket. The triple $(\mathcal{X}(\mathcal{M})[-1], L_Q; α_{\mathcal{M}})$ is also a Lie algebra object in the Gabriel-Zisman homotopy category $Π((C^{\infty}_{\mathcal{M}},Q)\mathrm{-}\mathbf{mod})$. In this paper, we describe the universal enveloping algebra of $(\mathcal{X}(\mathcal{M})[-1], L_Q; α_{\mathcal{M}})$ and prove that it is a Hopf algebra object in $Π((C^{\infty}_{\mathcal{M}},Q)\mathrm{-}\mathbf{mod})$. As an application, we study Fedosov dg Lie algebroids and recover a result of Stiénon, Xu, and the second author on the Hopf algebra arising from a Lie pair.

description: How is air traffic performance affected by type and location of markets? Is there any pattern to how air traffic performs with respect to the size and structure of markets, type of networks, and size of aircraft? In this paper, an empirical framework has been developed to examine the determinants of air traffic performance. Air traffic performance is defined as the ratio of airborne time to total rampto- ramp time. Using quarterly segment traffic data (i.e., T100 segment of Form 41) for the period 1995-2006, an econometric model is constructed to estimate and evaluate performance measures defined over market segments and networks. This econometric framework establishes and evaluates empirical linkages between performance measures and size of the markets, locations, distance, seasons of the year, and aircraft type over time. Statistical estimates indicate that size of market, type of aircraft, industry structure, and distance play important roles in influencing performance measures.

description: While planets are commonly discovered around main-sequence stars, the processes leading to their formation are still far from being understood. Current planet population synthesis models, which aim to describe the planet formation process from the protoplanetary disk phase to the time exoplanets are observed, rely on prescriptions for the underlying properties of protoplanetary disks where planets form and evolve. The recent development in measuring disk masses and disk-star interaction properties, i.e., mass accretion rates, in large samples of young stellar objects demand a more careful comparison between the models and the data. We performed an initial critical assessment of the assumptions made by planet synthesis population models by looking at the relation between mass accretion rates and disk masses in the models and in the currently available data. We find that the currently used disk models predict mass accretion rate in line with what is measured, but with a much lower spread of values than observed. This difference is mainly because the models have a smaller spread of viscous timescales than what is needed to reproduce the observations. We also find an overabundance of weakly accreting disks in the models where giant planets have formed with respect to observations of typical disks. We suggest that either fewer giant planets have formed in reality or that the prescription for planet accretion predicts accretion on the planets that is too high. Finally, the comparison of the properties of transition disks with large cavities confirms that in many of these objects the observed accretion rates are higher than those predicted by the models. On the other hand, PDS70, a transition disk with two detected giant planets in the cavity, shows mass accretion rates well in line with model predictions.

description: Statistical and artificial intelligence methods have successfully classified organizational solvency, but are limited in terms of generalization, knowledge on how a conclusion was reached, convergence to a local optima, or inconsistent results. Issues such as dimensionality reduction and feature selection can also affect a model’s performance. This research explores the use of the genetic algorithm that has the advantages of the artificial neural network but without its limitations. The genetic algorithm model resulted in a set of easy to understand, if-then rules that were used to assess U.S. air carrier solvency with a 94% accuracy.

description: We examine the fluctuations around a Dp-brane solution in an unstable D-brane system using boundary states and also boundary string field theory. We show that the fluctuations correctly reproduce the fields on the Dp-brane. Plugging these into the action of the unstable D-brane system, we recover not only the tension and RR charge, but also full effective action of the Dp-brane exactly. Our method works for general unstable D-brane systems and provides a simple proof of D-brane descent/ascent relations under the tachyon condensation. In the lowest dimensional unstable D-brane system, called K-matrix theory, D-branes are described in terms of operator algebra. We show the equivalence of the geometric and algebraic descriptions of a D-brane world-volume manifold using the equivalence between path integral and operator formulation of the boundary quantum mechanics. As a corollary, the Atiyah-Singer index theorem is naturally obtained by looking at the coupling to RR-fields. We also generalize the argument to type I string theory.

description: The increasing use of Internet booking facilities provides analysts with a rich data source of the profile of airline fares offered for a particular service as the time of departure approaches – “temporalfares- offered curves.” This paper offers a critical assessment of this form of analysis. It also reviews the empirical work that has been done using this type of data and synthesizes the information and insights that it can provide on the operations of an airline market. The subjects covered range from pricing strategies of low-cost and legacy carriers under different degrees of competition, to the extent to which there is price leadership in markets, and to ways in which airlines determine faresoffered when their schedules mean that their own services effectively compete with each other.

description: Due to the sparsity and irregularity of the point cloud data, methods that directly consume points have become popular. Among all point-based models, graph convolutional networks (GCN) lead to notable performance by fully preserving the data granularity and exploiting point interrelation. However, point-based networks spend a significant amount of time on data structuring (e.g., Farthest Point Sampling (FPS) and neighbor points querying), which limit the speed and scalability. In this paper, we present a method, named Grid-GCN, for fast and scalable point cloud learning. Grid-GCN uses a novel data structuring strategy, Coverage-Aware Grid Query (CAGQ). By leveraging the efficiency of grid space, CAGQ improves spatial coverage while reducing the theoretical time complexity. Compared with popular sampling methods such as Farthest Point Sampling (FPS) and Ball Query, CAGQ achieves up to 50X speed-up. With a Grid Context Aggregation (GCA) module, Grid-GCN achieves state-of-the-art performance on major point cloud classification and segmentation benchmarks with significantly faster runtime than previous studies. Remarkably, Grid-GCN achieves the inference speed of 50fps on ScanNet using 81920 points per scene as input.
Turbulent Diffusion of Magnetic Fields in Weakly Ionized Gas

description: The diffusion of uni-directional magnetic fields by two dimensional turbulent flows in a weakly ionized gas is studied. The fields here are orthogonal to the plane of fluid motion. This simple model arises in the context of the decay of the mean magnetic flux to mass ratio in the interstellar medium. When ions are strongly coupled to neutrals, the transport of a large--scale magnetic field is driven by both turbulent mixing and nonlinear, ambipolar drift. Using a standard homogeneous and Gaussian statistical model for turbulence, we show rigorously that a large-scale magnetic field can decay on at most turbulent mixing time scales when the field and neutral flow are strongly coupled. There is no enhancement of the decay rate by ambipolar diffusion. These results extend the Zeldovich theorem to encompass the regime of two dimensional flows and orthogonal magnetic fields, recently considered by Zweibel (2002). The limitation of the strong coupling approximation and its implications are discussed.

Bentham's Writings on Spain and Portugal
Creators: name: Schofield, P.
Publisher: name: UK Data Service
Year: 2010

description: The aim of the Bentham Project is to produce a new scholarly edition of the works and correspondence of Jeremy Bentham (1748-1832), the influential jurist, philosopher and social scientist, whom A.J.P. Taylor described as 'the most formidable reasoner who ever applied his gifts to the practical questions of administration and politics'.

The case for producing a new edition of Bentham's works rests partly on the importance of his thought, and partly on the inadequate and incomplete fashion in which his works were previously published. His writings are remarkable for their range, originality and influence. He was one of the greatest reformers, perhaps the greatest, in the history of English law. He was a major thinker in the disciplines of legal and political philosophy, ethics, public administration, social policy and economics. He has been recognised, too, as a pioneer in other fields ranging from international law and the birth control movement to motivational psychology and deontic logic.

The task of producing the new edition is a daunting one. It involves the exploration of a very substantial body of manuscript material, the principal collections being those of University College London and the British Library. Since 1968, twenty-five volumes of the new Collected Works have been published under the auspices of the Bentham Committee. It is envisaged that when complete the edition will comprise approximately seventy volumes, of which fourteen will be devoted to Bentham's correspondence. Such an edition will, it is hoped, make available a fuller and more inclusive view of Bentham's thought and of his contribution to the science of man and society than has been possible hitherto.

The files being deposited now relate to Bentham’s writings for Spain and Portugal.

description: This paper argues that a critical dimension in understanding the factors that inhibit the effectiveness and benefits of airline alliances is corporate transparency. Specifically, the issue of transparency in corporate governance is considered. Corporate governance is the set of institutional arrangements affecting corporate decision making, and deals with the relationship among various participants in determining the direction and performance of corporations. However, airline strategic alliances span an array of national cultures which influence the development of such relationships. The impact of national culture as a determinant of governance transparency is also investigated in this paper. This study draws on the literature which examines the impact of national culture on international joint ventures and governance systems. National cultures are described by Hofstede’s five dimensions of power distance, uncertainty avoidance, individualism, masculinity, and temporal orientation. Governance transparency is investigated by the examination of corporate annual reports. Thus, this study investigates not only the level of corporate governance transparency demonstrated by participants in each of the three major airline alliances, but the relationship between said governance transparency and the cultural identity of each of the participants.

description: Abstract Aim To provide an overview on the available treatments to prevent and reduce gynecomastia and/or breast pain caused by antiandrogen therapy for prostate cancer. Methods The German Society of Radiation Oncology (DEGRO) expert panel summarized available evidence published and assessed the validity of the information on efficacy and treatment-related toxicity. Results Eight randomized controlled trials and one meta-analysis were identified. Two randomized trials demonstrated that prophylactic radiation therapy (RT) using 1 × 10 Gy or 2 × 6 Gy significantly reduced the rate of gynecomastia but not breast pain, as compared to observation. A randomized dose-finding trial identified the daily dose of 20 mg tamoxifen (TMX) as the most effective prophylactic dose and another randomized trial described that daily TMX use was superior to weekly use. Another randomized trial showed that prophylactic daily TMX is more effective than TMX given at the onset of gynecomastia. Two other randomized trials described that TMX was clearly superior to anastrozole in reducing the risk for gynecomastia and/or breast pain. One comparative randomized trial between prophylactic RT using 1 × 12 Gy and TMX concluded that prophylactic TMX is more effective compared to prophylactic RT and furthermore that TMX appears to be more effective to treat gynecomastia and/or breast pain when symptoms are already present. A meta-analysis confirmed that both prophylactic RT and TMX can reduce the risk of gynecomastia and/or breast pain with TMX being more effective; however, the rate of side effects after TMX including dizziness and hot flushes might be higher than after RT and must be taken into account. Less is known regarding the comparative effectiveness of different radiation fractionation schedules and more modern RT techniques. Conclusions Prophylactic RT as well as daily TMX can significantly reduce the incidence of gynecomastia and/or breast pain. TMX appears to be an effective alternative to RT also as a therapeutic treatment in the presence of gynecomastia but its side effects and off-label use must be considered.

description: The problem of time in quantum gravity calls for a relational solution. Using quantum reduction maps, we establish a previously unknown equivalence between three approaches to relational quantum dynamics: 1) relational observables in the clock-neutral picture of Dirac quantization, 2) Page and Wootters' (PW) Schrödinger picture formalism, and 3) the relational Heisenberg picture obtained via symmetry reduction. Constituting three faces of the same dynamics, we call this equivalence the trinity. We develop a quantization procedure for relational Dirac observables using covariant POVMs which encompass non-ideal clocks. The quantum reduction maps reveal this procedure as the quantum analog of gauge-invariantly extending gauge-fixed quantities. We establish algebraic properties of these relational observables. We extend a recent clock-neutral approach to changing temporal reference frames, transforming relational observables and states, and demonstrate a clock dependent temporal nonlocality effect. We show that Kuchař's criticism, alleging that the conditional probabilities of the PW formalism violate the constraint, is incorrect. They are a quantum analog of a gauge-fixed description of a gauge-invariant quantity and equivalent to the manifestly gauge-invariant evaluation of relational observables in the physical inner product. The trinity furthermore resolves a previously reported normalization ambiguity and clarifies the role of entanglement in the PW formalism. The trinity finally permits us to resolve Kuchař's criticism that the PW formalism yields wrong propagators by showing how conditional probabilities of relational observables give the correct transition probabilities. Unlike previous proposals, our resolution does not invoke approximations, ideal clocks or ancilla systems, is manifestly gauge-invariant, and easily extends to an arbitrary number of conditionings.

description: This study investigates the perceived importance of 36 carrier selection variables to both motor carriers and shippers. The ranking discrepancies identified indicate that shippers and carriers do not classify certain motor carrier selection variables similarly. Fortunately, motor carrier perceptions have improved since the Abshire and Premeaux (1991) study. To enhance shipper satisfaction, carriers must emphasize the more important selection variables. Specifically, carriers need to focus on offering more flexible rates, respond effectively to emergency or unexpected situations, and provide information and services through a comprehensive, Web-enhanced, electronic-data-interchange.

description: The recent results of IceCube Neutrino Observatory include an excess of PeV neutrino events which appear to follow a broken power law different from the other lower energy neutrinos detected by IceCube. The possible astrophysical source of these neutrinos is still unknown. One possible source of such neutrinos could be the decay of non-thermal, long-living heavy mass Dark Matter, whose mass should be $> 10^{6} \rm {GeV}$ and could have produced at the very early Universe. They can undergo cascading decay via both hadronic and leptonic channels to finally produce such high energy neutrinos. This possibility has been explored in this work by studying the decay flux of these Dark Matter candidates. The mass and lifetime of such Dark Matter particles have been obtained by performing a $χ^2$ fit with the PeV neutrino data of IceCube. We finally estimate the baryon asymmetry produced in the Universe due to such Dark Matter decay.

description: We unearth spacetime structure of massive vector bosons, gravitinos, and gravitons. While the curvatures associated with these particles carry a definite spin, the underlying potentials cannot be, and should not be, interpreted as single spin objects. For instance, we predict that a spin measurement in the rest frame of a massive gravitino will yield the result 3/2 with probability one half, and 1/2 with probability one half. The simplest scenario leaves the Riemannian curvature unaltered; thus avoiding conflicts with classical tests of the theory of general relativity. However, the quantum structure acquires additional contributions to the propagators, and it gives rise to additional phases.

description: The Transport System of the Recife Metropolitan Area is under change. As a subsidy to its change an efficiency analysis is done with the purpose of highlighting characteristics of the efficient systems. Nineteen transport systems are analyzed, twelve from several countries in Europe and seven from Brazil: nine from Europe and only one from Brazil were found efficient. These systems are characterized by very different power structure and tariff structure. Efficient ones adopted a more democratic power partition among communalities and established a more broad system of tariffs. Among other lessons it is suggested that RMR adopts a structure that allows a more equal partition of the several municipalities comprising the Metro Area including representatives of users groups like workers associations and syndicates. Also it should adopt a more flexible tariff systems giving advantages to usual users at the same time that decreases costs and improves the operational efficiency.

Let $L$ be a totally real field. Under (a special case of) the absolute Hodge conjecture and a weak Serre's conjecture for mod $\ell$ representations of the absolute Galois group of $L$, we prove that the same holds also for the $\mathcal{O}_{L,S}$-points.

description: The English Church Census, 2005 followed-up from English Church Census, 1989 (available from the UKDA under SN 2842). The project surveyed each of the 37,000 churches in England and the response rate was 50 percent. The main form was completed by someone in authority and provides key characteristics of the church, its leadership, the congregation (size and frequency of attendance, age, ethnicity), ethos ('churchmanship' or theology), midweek activities, community service and so on. A very brief, anonymous form was also given to each person attending on census day asking for gender, broad age category and frequency of attendance. The counts obtained from these slips were recorded for each church, but no individual-level data are held.

The English Church Census, 2005 had a two-fold aim:
to provide the best information available on the extent of religious activity by Christians in England

to make progress in answering a number of important questions about contemporary religious practice

Analysis of data from 54 transit agencies, using structural equations, revealed that strategic planning enhances a transit agency’s ability to respond effectively to federal legislative requirements and demands of host communities. This is particularly so when it is designed to consolidate the various unit action-plans into a system-wide strategic plan. Additionally, for strategic planning to be effective, it should receive more than a lip service from top and unit or division level managers, it requires the involvement and commitment of top and division or unit managers, and it should be designed to have an external orientation. That is, it should focus on an organization’s responsiveness to the demands of its customers and it should identify and exploit future growth opportunities. Furthermore, effective strategic planning requires involvement of employees, particularly those who will be responsible for the implementation of the resulting plan, and it must fit the management and decision making styles of the top and unit or division level managers. These characteristics are intended to provide guidelines to agencies intending to use strategic planning as a tool of effective strategic management.

description: Infrared reflectance measurements were made on the single crystal pyrochlore Cd$_{2}$Os$_{2}$O$_{7}$ in order to examine the transformations of the electronic structure and crystal lattice across the boundary of the metal insulator transition at $T_{MIT}=226K$. All predicted IR active phonons are observed in the conductivity over all temperatures and the oscillator strength is found to be temperature independent. These results indicate that charge ordering plays only a minor role in the MIT and that the transition is strictly electronic in nature. The conductivity shows the clear opening of a gap with $2Δ=5.2k_{B}T_{MIT}$. The gap opens continuously, with a temperature dependence similar to that of BCS superconductors, and the gap edge having a distinct $σ(ω)\thicksimω^{1/2}$ dependence. All of these observables support the suggestion of a Slater transition in Cd$_{2}% $Os$_{2}$O$_{7}$.

description: We consider holographic RG flow solutions with eight supersymmetries and study the geometry transverse to the brane. For both M2-branes and for D3-branes in F-theory this leads to an eight-manifold with only a four-form flux. In both settings there is a natural four-dimensional hyper-Kahler slice that appears on the Coulomb branch. In the IIB theory this hyper-Kahler manifold encodes the Seiberg-Witten coupling over the Coulomb branch of a U(1) probe theory. We focus primarily upon a new flow solution in M-theory. This solution is first obtained using gauged supergravity and then lifted to eleven dimensions. In this new solution, the brane probes have an Eguchi-Hanson moduli space with the M2-branes spread over the non-trivial 2-sphere. It is also shown that the new solution is valid for a class of orbifold theories. We discuss how the hyper-Kahler structure on the slice extends to some form of G-structure in the eight-manifold, and describe how this can be computed.

description: Worldwide, around two million women experience stillbirth each year. Most of these deaths are
preventable. Action to improve timely, equitable access to high-quality care is urgently needed to
prevent these deaths but must be coupled with action to improve the supportive care that bereaved
women receive to reduce psychological morbidity.

description: In recent years, the scalar field dark matter (SFDM), also called ultralight bosonic dark matter, has received considerable attention due to the number of problems it might help to solve. Among these are the cusp-core problem and the abundance of small structures of the standard cold dark matter (CDM) model. In this paper we show that multi-state solutions of the low energy and weak gravitational field limit of field equations, interpreted as galactic halo density profiles, can provide a possible explanation to the anisotropic distribution of satellite galaxies observed in the Milky Way, M31 and Centaurus A, where satellites trajectories seem to concentrate on planes close to the poles of the galaxies instead of following homogeneously distributed trajectories. The core hypothesis is that multi-state solutions of the equations describing the dynamics of this dark matter candidate, namely, the Gross-Pitaevskii-Poisson equations, with monopolar and dipolar contributions, can possibly explain the anisotropy of satellite trajectories. In order to construct a proof of concept, we study the trajectories of a number of test particles traveling on top of the gravitational potential due to a multi-state halo with modes (1,0,0)+(2,1,0). The result is that particles accumulate asymptotically in time on planes passing close to the poles. Satellite galaxies are not test particles but interpreted as such, our results indicate that in the asymptotic time their trajectories do not distribute isotropically, instead they prefer to have orbital poles accumulating near the equatorial plane of the multistate halo. The concentration of orbital poles depends on whether the potential is monopolar or dipolar dominated.

description: U.S. agricultural output more than doubled between 1948 and 2011, with growth averaging 1.49 percent per year. With little growth in total measured use of agricultural inputs, the extraordinary performance of the U.S. farm sector was driven mainly by increases in total factor productivity (TFP—measured as output per unit of aggregate input). Over the last six decades, the mix of agricultural inputs used shifted significantly, with increased use of intermediate goods (e.g., fertilizer and pesticides) and less use of labor and land. The output mix changed as well, with crop production growing faster than livestock production. Based on econometric analysis of updated (1948-2011) TFP data, this study finds no statistical evidence that longrun U.S. agricultural productivity has slowed over time. Model-based projections show that in the future, slow growth in research and development investments may have only minor effects on TFP growth over the next 10 years but will slow TFP growth much more over the long term.
Towards \the river and the sea\" and beyond : revelations in T.S. Eliot's landscape imagery 1927-1942"

description: Of major literary interest because he attained almost pontifical status in English poetry, drama and criticism for an extended period in the twentieth century, T.S. Eliot appears today to have been a writer of apparently baffling complexity. An important aspect of this phenomenon is that his poetry (which generally shows every evidence of great deliberation in its composition) appears often to subvert his critical dicta. However, Eliot's landscape imagery, which derives very largely from his own experience and beliefs, particularly in his childhood and youth, faithfully reflects a variety of aspects of his personality. This exploitation of imagery of landscape, extending far beyond conventional topography to figurative and psychological landscapes in many forms, is an inheritance from, and a development of, major elements of the 'Romantic' sensibility of the early nineteenth century. Landscape plays an important part, too, in much of the 'Modernist'-influenced poetry of the Thirties in England, not least as a peculiarly individual source of material which nonetheless offers common interfaces. Thus, analysis of the manner in which both individual and common elements of their experience of landscape are treated by Eliot vis-a-vis his contemporaries, particularly Yeats and Auden, reveals some of the real premises and syllogisms underlying his work.

description: An estimated 21.6 million truck trips are made each year on Washington state highways. An estimated 45% of that transported freight originated from or is destined for a warehouse or distribution center within the state. The growing amount of congestion within the state of Washington has prompted concern over the state’s ability to anticipate and provide for current and future freight transportation infrastructure needs. The general objective of this paper is to investigate the operations and transportation usage of warehouse/distribution centers in Washington. Three specific objectives were outlined for this research. 1) Provide a description of the common operations and functions performed in the warehouse/ distribution center industry and assess those characteristics associated with warehouses in Washington. 2) Determine the relationship of warehouse size, and inbound and outbound truck movement as variables in the warehouse/distribution center industry based upon warehouse functions in relation to facility location. Warehouses in the state of Washington are sorted into two regions, eastern and western. 3) Evaluate the same three issues in relation to warehouse functions and whether they are involved with international trade. Warehouses within the state were sorted into two warehouse types, international and domestic. A survey of warehouses in the state yielded information from 142 firms broadly distributed across the state. A multiple linear regression utilizing the stepwise function is performed in SAS to evaluate, among others, the relationships among warehouse size, and inbound and outbound truck movement relative to warehouse functions. Findings include the fact public warehouses serve a critical role in the number of truckloads occurring within eastern Washington. Meanwhile, cold storage and ‘Other’ warehouse facilities generate a large number of truckloads in western Washington. Warehouses in eastern Washington operating a private fleet are typically smaller, while western warehouses outsourcing to third-party providers are larger. A noticeable increase occurs in the number of truckloads for domestic warehouses that offer cross-docking services and handle a greater number of products. For international warehouses, cold storage facilities have significantly more truckload movement than other facilities types. The size of both domestic and international warehouses is significantly influenced by the number of bays and employees within a facility. Variations by commodity being handled are analyzed in the paper as well.
