Library Web sites

description: A website can provide a powerful way for an organization to communicate with the public. Although organizations often place a large degree of effort in website creation, they typically neglect to consider ongoing maintenance, which is critical in an environment where content, technology, and people evolve. In this paper we conduct a redesign of the Durham County Public Library site. As with many organizations, the Library is short-staffed and their website suffers from outdated content, inconsistent design and poor navigation. Using the Library as a case study, we critique the original website, then propose a new design. Our subsequent implementation and evaluation showed the new design conforms to W3C priority one accessibility guidelines, is ten times smaller, downloads ten times faster, and is easier to update. This case study lends further evidence as to the importance of a good web site design for ongoing maintenance.
Nonlinear Quantum Search

Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: Although quant mech is linear, there are nevertheless quant sys with multiple interacting particles in which the effective evo of a single particle is governed by a nonlinear eq. This includes Bose-Einstein condensates, which are gov by the Gross-Pitaevskii eq (GPE), which is a cubic nonlin Schrodinger eq (NLSE) with a term propto $|ψ|^2ψ$. Evo by this eq solves the unstruct search prob in const time, but at the novel expense of increasing the time-measurement precision. Jointly optimizing these resources results in an overall scaling of $N^{1/4}$, which is a significant, but not unreasonable, improvement over the $N^{1/2}$ scaling of Grover's algo. Since the GPE effectively approx the multi-particle Schrodinger eq, for which Grover's algo is optimal, our result leads to a quant info-theoretic bound on the num of particles needed for this approx to hold, asymp. The GPE is not the only nonlin of the form $f(|ψ|^2)ψ$ that arises in effective eqs for the evo of real quant phys sys, however: The cubic-quintic NLSE describes light propagation in nonlin Kerr media with defocusing corrections, and the log NLSE describes Bose liquids under certain cond. Analysis of comput with such sys yields some surprising results; e.g., when time-measurement precision is included in the resource accounting, searching a "database" when there is a single correct ans may be easier than searching when there are multiple correct ans. These results lead to quant info-theoretic bounds on the phys resources required for these effective nonlin theories to hold, asymp. Further, strongly reg graphs, which have no global sym, are sufficiently complete for quant search on them to asymp behave like unstruct search. Certain suff complete graphs retain the improved runtime and resource scalings for some nonlin, so our scheme for nonlin, analog quant comput retains its benefits even when some struct is introduced.

description: We study the possibility to populate the dark sector through a phase transition. We will consider secluded dark sectors made of gauge theories, Randall-Sundrum scenarios and conformally coupled elementary particles. These sectors have in common the fact that the action is approximately Weyl invariant, implying that particle production due to time dependent background is strongly suppressed. In particular no significant production takes place during inflation allowing to avoid strong isocurvature constraints from CMB. As we will show, if the scale of inflation is large compared to the dynamical mass scale, these sectors automatically undergo a phase transition that in the simplest cases is controlled by the Hubble parameter. If the phase transition takes place during reheating or radiation the abundance obtained can be larger than particle production and production from the SM plasma. For phase transitions completing during radiation domination, the DM mass is predicted in the range $10^8$ GeV while larger values are required for phase transitions occurring during reheating.

title: Die Fruchtbarkeit von Multiparadigmatik
Creators: name: Schleif, Linda
Year: 2023

description: In dieser Arbeit wird die Rolle der Wissenschaftstheorie in der Kommunikationswissenschaft unter Zuhilfenahme des Paradigmenkonzepts in Anlehnung an Kuhn diskutiert. Dabei wird beispielhaft die Entwicklung der Kommunikationssoziologie unter Bezugnahme auf externe Legitimationskämpfe und sozio-kulturelle Einflussfaktoren historisch nachgezeichnet und ihr Spannungsverhältnis als Teildisziplin der Kommunikationswissenschaft und der Soziologie dargelegt. Die hieraus resultierenden wissenschaftstheoretischen Diskurse werden vorgestellt und ihre Grundannahmen präsentiert. In der sich anschließenden Reflexion werden übergreifende Problembereiche und Gemeinsamkeiten herausgestellt, welche die Basis der nachgelagerten Analyse bilden. Die Analyse zeigt, dass die Unklarheit der Verhältnisbestimmungen der in der Kommunikationssoziologie angewandten wissenschaftstheoretischen Paradigmen per se keinen fruchtbaren Zustand darstellt. Die Argumentation einer der Sozialwissenschaften inhärenten Notwendigkeit und Fortschrittlichkeit dieses multiparadigmatischen Zustands wird dekonstruiert. Ob die Vielfalt der Ansätze eher als forschungshemmend oder als produktiv wirkt, hängt davon ab, ob bzw. wie man die Paradigmen in Beziehung zueinander setzt. Es wird argumentiert, dass der multiparadigmatische Zustand bisher ungenutztes Potential besitzt, mittels einer grundlegenden Verhältnisbestimmung in eine holistische Struktur überführt zu werden. Im zweiten Teil der Analyse wird ein Beispiel präsentiert, wie dieses komplexe Unterfangen gelingen kann. Im Zuge einer empirischen Überprüfung des Erklärungsgehaltes für die Teildisziplin werden die Paradigmen auf ihre epistemische Kommensurabilität untersucht und in einem organisierten Gesamtbild der kommunikationssoziologischen Wissenschaftstheorie zueinander in Beziehung gesetzt. Der erarbeitete Vorschlag für die Verhältnisbestimmung der Paradigmen eröffnet die Möglichkeit neue Kooperationspotentiale zwischen den Paradigmen (auch für andere Teildisziplinen) zu realisieren. Es sind weitere dieser Grundlegungen nötig, um ein produktives interparadigmatisches Verhältnis und kommunikationswissenschaftlich relevante basistheoretische Annahmen zu etablieren, welche die immer noch dominante paradigmatische Ignoranz überwinden und einen fruchtbaren Dialog ermöglichen können.

description: We consider the restricted subsets of $\mathbb{N}_n=\{1,2,\ldots,n\}$ with $q\geq1$ being the largest member of the set $\mathcal{Q}$ of disallowed differences between subset elements. We obtain new results on various classes of problem involving such combinations lacking specified separations. In particular, we find recursion relations for the number of $k$-subsets for any $\mathcal{Q}$ when $|\mathbb{N}_q-\mathcal{Q}|\leq2$. The results are obtained, in a quick and intuitive manner, as a consequence of a bijection we give between such subsets and the restricted-overlap tilings of an $(n+q)$-board (a linear array of $n+q$ square cells of unit width) with squares ($1\times1$ tiles) and combs. A $(w_1,g_1,w_2,g_2,\ldots,g_{t-1},w_t)$-comb is composed of $t$ sub-tiles known as teeth. The $i$-th tooth in the comb has width $w_i$ and is separated from the $(i+1)$-th tooth by a gap of width $g_i$. Here we only consider combs with $w_i,g_i\in\mathbb{Z}^+$. When performing a restricted-overlap tiling of a board with such combs and squares, the leftmost cell of a tile must be placed in an empty cell whereas the remaining cells in the tile are permitted to overlap other non-leftmost filled cells of tiles already on the board.

description: This study describes a quantitative content analysis of promotional materials found in five sampled branches of an urban library system.  The content analysis was conducted to determine if elements of diverse teen populations were represented in the promotional materials distributed and on display in the library branches.  Materials analyzed included brochures, business cards, flyers, posters, signs, and other advertising techniques such as displays.  The materials included illustrations of race/ethnicity, gender, sexual orientation, religion, disability, and socioeconomic status.  Each sampled branch presented different numbers and types of resources.  Sampled community branches offered more variety of promotional resources than the larger, central library branches.  A need for a more uniform distribution of promotional materials throughout the library system as well as templates for materials created by individual branches is justified.  Suggested practices for future marketing of services to diverse teens are included.

description: Assessing the validity of a real-world system with respect to given quality criteria is a common yet costly task in industrial applications due to the vast number of required real-world tests. Validating such systems by means of simulation offers a promising and less expensive alternative, but requires an assessment of the simulation accuracy and therefore end-to-end measurements. Additionally, covariate shifts between simulations and actual usage can cause difficulties for estimating the reliability of such systems. In this work, we present a validation method that propagates bounds on distributional discrepancy measures through a composite system, thereby allowing us to derive an upper bound on the failure probability of the real system from potentially inaccurate simulations. Each propagation step entails an optimization problem, where -- for measures such as maximum mean discrepancy (MMD) -- we develop tight convex relaxations based on semidefinite programs. We demonstrate that our propagation method yields valid and useful bounds for composite systems exhibiting a variety of realistic effects. In particular, we show that the proposed method can successfully account for data shifts within the experimental design as well as model inaccuracies within the simulation.

description: This study examines the role of illuminated manuscript facsimiles in the research process of art historians focusing on the medieval and Byzantine periods, exploring this role in comparison with other illuminated manuscript reproductions, such as digital facsimiles, surveys, and monographs.
Through interviews with art historians and study of the reproductions themselves, it was concluded that the full context of the work is crucial, and that manuscript reproductions must come as close as possible to reproducing the experience of handling the art-object-as-book to serve their intended purpose.  Additionally, the trend of resource-guided research appeared, a circumstance in which the facsimiles available to the art historian guided or determined their course of study.  Finally, art historians used different kinds of image resources for different information needs, suggesting the importance of developing, providing, and advertising a variety of resources that incorporate the experiential context of the original manuscript.
A Study of the Demand-Driven Acquisition of E-Book Titles in an Academic Library

Acquisition of electronic books--Libraries

description: A growing trend in collection development among academic libraries is demand driven acquisition (DDA) of e-books, which involves loading large batches of records that meet a library's bibliographic profile into the online catalog.  Materials can typically be accessed by patrons as a short-term loan for two or three times before purchase of the title is automatically triggered.  This study examined the costs of DDA for a large academic library that went directly to purchase, bypassing the lending process.  Pricing information was obtained for each title and circulation information was obtained from the e-book vendor.  These data were also collected for e-books that were acquired through approval plan selection.  This information was used to generate cost per use data.  These numbers were compared to determine whether DDA resulted in a lower cost per use than approval plan selection.

description: COELIOXYS (RHINOCOELIOXYS) MITCHELL, 1973
Type species: Coelioxys zapoteca Cresson, 1878.
Diagnosis: The following characteristics combined (four for either sex) separate species of C. (Rhinocoelioxys) from all the other subgenera. Mesoscutellum with a distinct longitudinal median ridge (Fig. 51); posterior margin of mesoscutellum obtusely produced medially into a blunt edge (Fig. 51); axilla long, free apical portion longer or subequal to basal portion (Fig. 51); ocular hairs long (~0.12 mm) (Fig. 5). Female: S6 lateral notches obsolete, a weak impression, not interrupting outline in dorsal view (Fig. 65). Male: postgradular areas of T 2 and T 3 with a transverse, punctate area either formed by punctures that may be fused or by few smaller punctures basally and larger punctures apicolaterally (Fig. 66).
Comments: The phylogenetic results indicate that C. (Rhinocoelioxys) as previously defined is polyphyletic. The type species C. zapoteca as well as C. agilis and Coelioxys platygnatha Rocha-Filho & Packer, 2015 are in a different clade from the other four species that were included by Rocha-Filho & Packer (2015), which are now transferred to C. (Austrocleptria) subgen. nov. (see below). The three species are Neotropical. Rocha-Filho & Packer (2015) revised and keyed the species of this subgenus [as well as those of C. (Austrocleptria) subgen. nov.].

description: We discuss the behaviour of the Larmor frequency shift and the longitudinal relaxation rate due to non-uniform electromagnetic fields on an assembly of spin 1/2 particles, in adiabatic and nonadiabatic regimes. We also show some general relations between the various frequency shifts and between the frequency shifts and relaxation rates. The remarkable feature of all our results is that they were obtained without any specific assumptions on the explicit form of the correlation functions of the fields. Hence, we expect that our results are valid both for diffusive and ballistic regime of motion and arbitrary cell shapes and surface scattering. These results can then be applied to a wide variety of realistic systems.

description: This paper reports the results of four case studies of recreational reading in high school media centers. Interviews were conducted with media specialists and websites were analyzed for the presence of items related to recreational reading. The four North Carolina high schools in this study participate in a variety of activities to promote recreational reading, including programming, readers' advisory services, and public relations. Common programs include contests, author visits, book groups, and curriculum-related projects. The media specialists suggest books to students and teachers, in addition to offering bibliographies and other indirect readers' advisory resources. Public relations efforts prevalent in the four schools involve booktalks, displays, and book reviews on the media center website. Media specialists also discussed their attitudes toward recreational reading, affirming that they value recreational reading. The librarians cited testing and busy student schedules as reducing the amount of time the students spend reading recreationally.
Modelling the formation of the circumnuclear ring in the Galactic centre

Year: 2015
Subjects: subject: Astrophysics of Galaxies (astro-ph.GA)

description: Several thousand solar masses of molecular, atomic and ionized gas lie in the innermost ~10 pc of our Galaxy. The most relevant structure of molecular gas is the circumnuclear ring (CNR), a dense and clumpy ring surrounding the supermassive black hole (SMBH), with a radius of ~2 pc. We propose that the CNR formed through the tidal disruption of a molecular cloud, and we investigate this scenario by means of N-body smoothed-particle hydrodynamics simulations. We ran a grid of simulations with different cloud mass (4X10^4, 1.3X10^5 solar masses), different initial orbital velocity (v_in=0.2-0.5 v_esc, where v_esc is the escape velocity from the SMBH), and different impact parameter (b=8, 26 pc). The disruption of the molecular cloud leads to the formation of very dense and clumpy gas rings, containing most of the initial cloud mass. If the initial orbital velocity of the cloud is sufficiently low (v_in<0.4 v_esc, for b=26 pc) or the impact parameter is sufficiently small (b<10 pc, for v_in>0.5 v_esc), at least two rings form around the SMBH: an inner ring (with radius ~0.4 pc) and an outer ring (with radius ~2-4 pc). The inner ring forms from low-angular momentum material that engulfs the SMBH during the first periapsis passage, while the outer ring forms later, during the subsequent periapsis passages of the disrupted cloud. The inner and outer rings are misaligned by ~24 degrees, because they form from different gas streamers, which are affected by the SMBH gravitational focusing in different ways. The outer ring matches several properties (mass, rotation velocity, temperature, clumpiness) of the CNR in our Galactic centre. We speculate that the inner ring might account for the neutral gas observed in the central cavity.

We model such processes with couples of damped/amplified oscillators which provide time dependent representation of Bessel equation. The root loci of poles and zeros conform to solutions of K-sets. Some light is shed on the problem of filling the gap between the cellular level dynamics and the brain functional activity. Breakdown of time-reversal symmetry is related with the cortex thermodynamic features. This provides a possible mechanism to deduce lifetime of recorded memory.

description: The description of medieval liturgical manuscripts has been problematic throughout the years. Until the recent publication of Descriptive Cataloging for Medieval, Renaissance, and Early Modern Manuscripts (AMREMM), catalogers in a general library setting had no adequate standards for creating AACR2-compatible records for these items. This paper describes issues encountered while cataloging reproductions of medieval liturgical manuscripts. It also provides general information to assist the non-specialist cataloger who lacks a background in medieval studies in describing medieval liturgical manuscripts. The paper discusses the use of outside sources, search techniques for locating copy in OCLC, the provision of subject access, and offers a brief introduction to medieval Western liturgy and liturgical books.

description: In neutrinoless double beta (0νββ) decay experiments, the diversity of topological signatures of different particles provides an important tool to distinguish double beta events from background events and reduce background rates. Aiming at suppressing the single-electron backgrounds which are most challenging, several groups have established Monte Carlo simulation packages to study the topological characteristics of single-electron events and 0νββ events and develop methods to differentiate them. In this paper, applying the knowledge of graph theory, a new topological signature called REF track (Refined Energy-Filtered track) is proposed and proven to be an accurate approximation of the real particle trajectory. Based on the analysis of the energy depositions along the REF track of single-electron events and 0νββ events, the REF energy deposition models for both events are proposed to indicate the significant differences between them. With these differences, this paper presents a new discrimination method, which, in the Monte Carlo simulation, achieved a single-electron rejection factor of 93.8+-0.3 (stat.)% as well as a 0νββ efficiency of 85.6+-0.4 (stat.)% with optimized parameters in CdZnTe.

description: Recently, fractional Chern insulators (FCIs), also called fractional quantum anomalous Hall (FQAH) states, have been theoretically established in lattice systems with topological flat bands. These systems exhibit similar fractionalization phenomena as the conventional fractional quantum Hall (FQH) systems. Using the mapping relationship between the FQH states and the FCI/FQAH states, we construct the many-body wave functions of the fermionic FCI/FQAH states on the disk geometry with the aid of the generalized Pauli principle (GPP) and the Jack polynomials. Compared with the ground state by exact diagonalization method, the wave-function overlap is higher than $0.97$ even when the Hilbert space dimension is as large as $3\times10^6$. We also use the GPP and the Jack polynomials to construct edge excitations for the ferminoic FCI/FQAH states. The quasi-degeneracy sequences of fermionic FCI/FQAH systems reproduce the prediction of the chiral Luttinger liquid theory, complementing the exact diagonalization results with larger lattice sizes and more particles.

description: This study is a qualitative, investigative study into the information seeking behaviors and  needs of composers of electro-acoustic music. These composers have interdisciplinary  information needs that range from music to computer science to mathematics and  beyond. Throughout the paper, basic concepts and trends in the field of electro-acoustic  music are clarified for the reader. In addition to a literature review, interviews were  conducted with five composers. These interviews focused on information needs that  come about as a direct result of composing as well how the subjects stayed connected  with others in the field. Based on the interviews, the development of an information  seeking model was deemed to be an insufficient way to represent the complex creative  process that goes into the creation of a work of electro-acoustic music. Six  recommendations are put forth for information professionals interested in better serving  this community.

description: Although many of works have been done in multivalued quantum logic synthesis, the question whether multivalued quantum circuits are more efficient than the conventional binary quantum circuits is still open. In this article we devote to the optimization of generic multivalued quantum circuits. The multivalued quantum Shannon decompositions (QSD) are improved so that the circuits obtained are asymptotically optimal for all dimensionality d. The syntheses of uniformly multifold controlled $R_y$ rotations are also optimized to make the circuits further simplified. Moreover, the theoretical lower bound of complexity for multivalued quantum circuits is investigated, and a quantity known as efficiency index is proposed to evaluate the efficiency of synthesis of various quantum circuits. The algorithm for qudit circuits given here is an efficient synthesis routine which produces best known results for all dimensionality d, and for both cases the number of qudit n is small and that is asymptotic. The multivalued quantum circuits are indeed more efficient than the binary quantum circuits. The facts, the leading factor of the lower bound of complexity for qudit circuits is small by a factor of d-1 in comparison to that for qubit circuits and the asymptotic efficiency index is increased with the increase of dimensionality d, reveal the potential advantage of qudit circuits over generic qubit circuits. The generic n-qudit circuits with $d\geq5$ and generic two-ququart circuits synthesized by the algorithm given here are practical circuits which are more efficient than the most efficient qubit circuits.

description: Designing experiments for generalized linear models is difficult because optimal designs depend on unknown parameters. Here we investigate local optimality. We propose to study for a given design its region of optimality in parameter space. Often these regions are semi-algebraic and feature interesting symmetries. We demonstrate this with the Rasch Poisson counts model. For any given interaction order between the explanatory variables we give a characterization of the regions of optimality of a special saturated design. This extends known results from the case of no interaction. We also give an algebraic and geometric perspective on optimality of experimental designs for the Rasch Poisson counts model using polyhedral and spectrahedral geometry.

description: COELIOXYS (SYNOCOELIOXYS) MITCHELL, 1973
Type species: Coelioxys texana Cresson, 1872.
Diagnosis: This is the only Coelioxys subgenus and perhaps the only members of the Megachilini in which the male S7 is bilobed (Fig. 94H) rather than divided into two small sclerites (Baker, 1975: fig. 26D). Some characteristics such as the scale-like pubescence in parts of the body (Fig. 32), the inner ramus of pretarsal claws in females acute (Fig. 36), and apicodorsal processes of T 6 in males forked (Fig. 34) are shared only with species of the Old World subgenus C. (Allocoelioxys). Species belonging to C. (Synocoelioxys) are characterized by the following combination of characteristics that separates them from all other subgenera. Median ocellus surrounded by a swollen and nearly impunctate area (Fig. 32). Female: lateral margins of T 6 apex with long thick hairs forming an inconspicuous fringe (Fig. 33); S6 rounded or elliptical, not notched and straight (Fig. 33), not flexed downwards. Male: T 6 apicodorsal processes forked, with processes flattened, pointed, and irregular, almost forming a crenulate plate (Fig. 34), and T 7 exposed, with a long median tooth-like process medially (Baker, 1975: fig. 13A).
Comments: Species of C. (Synocoelioxys) are primarily Nearctic; five of them were revised and keyed by Baker (1975); another two, Coelioxys toltecoides Cockerell, 1923 from Mexico and Coelioxys tegularis Cresson, 1869 from Cuba, are also assigned to the subgenus (Ascher & Pickering, 2015).
List of species: Coelioxys alternata Say, 1837, Coelioxys apacheorum Cockerell, 1900, Coelioxys erysimi Cockerell, 1912, Coelioxys hunteri Crawford, 1914, C. tegularis *, C. texana, and C. toltecoides.

Spending too much time at the Galactic bar: chaotic fanning of the Ophiuchus stream

description: The Ophiuchus stellar stream is peculiar: (1) its length is short given the age of its constituent stars, and (2) several probable member stars that lie close in both sky position and velocity have dispersions in these dimensions that far exceed those seen within the stream. The stream's proximity to the Galactic center suggests that the bar must have a significant influence on its dynamical history: The triaxiality and time-dependence of the bar may generate chaotic orbits in the vicinity of the stream that can greatly affect its morphology. We explore this hypothesis with models of stream formation along orbits consistent with Ophiuchus' properties in a Milky Way potential model that includes a rotating bar. We find that in all choices for the rotation parameters of the bar, orbits fit to the stream are strongly chaotic. Mock streams generated along these orbits qualitatively match the observed properties of the stream: because of chaos, stars stripped early generally form low-density, high-dispersion "fans" leaving only the most recently disrupted material detectable as a strong over-density. Our models predict that there should be more low-surface-brightness tidal debris than detected so far, likely with a complex phase-space morphology. The existence of or lack of these features around the Ophiuchus stream would provide an interesting constraint on the properties of the Milky Way bar and would help distinguish between formation scenarios for the stream. This is the first time that chaos has been used to explain the properties of a stellar stream and is the first demonstration of the dynamical importance of chaos in the Galactic halo. The existence of long, thin streams around the Milky Way---presumably formed along non- or weakly-chaotic orbits---may represent only a subset of the total population of disrupted satellites.

A minimization principle for the description of time-dependent modes associated with transient instabilities

description: We introduce a minimization formulation for the determination of a finite-dimensional, time-dependent, orthonormal basis that captures directions of the phase space associated with transient instabilities. While these instabilities have finite lifetime they can play a crucial role by either altering the system dynamics through the activation of other instabilities, or by creating sudden nonlinear energy transfers that lead to extreme responses. However, their essentially transient character makes their description a particularly challenging task. We develop a minimization framework that focuses on the optimal approximation of the system dynamics in the neighborhood of the system state. This minimization formulation results in differential equations that evolve a time-dependent basis so that it optimally approximates the most unstable directions. We demonstrate the capability of the method for two families of problems: i) linear systems including the advection-diffusion operator in a strongly non-normal regime as well as the Orr-Sommerfeld/Squire operator, and ii) nonlinear problems including a low-dimensional system with transient instabilities and the vertical jet in crossflow. We demonstrate that the time-dependent subspace captures the strongly transient non-normal energy growth (in the short time regime), while for longer times the modes capture the expected asymptotic behavior.

description: United States mobile phone usage is on the rise, and catching up with countries abroad. Overseas, companies have experimented with a new way to deliver mobile content through the use of proximity marketing. Using Bluetooth technology, information can be delivered to mobile device users as they walk in designated physical vicinity. This information is often promotional marketing material for a nearby business. Recently, small US companies have launched pilot campaigns in urban areas such as Los Angeles. The service is still very early in its implementation, but plans to expand to other malls. Understanding user interactions and attitudes towards this technology will allow companies to make the system more useful and relevant to customers. In this study an online survey was sent to Los Angeles area mall patrons.  The survey questions were designed to gauge their familiarity with the technology, understand their preferences and identify areas to improve the usefulness of the service. The results of the survey revealed many insights including users' preference for large incentives, timely information and high personalization. In addition, it is noted that many technical issues need to be resolved such as compatibility with popular mobile devices.

description: Fredericton, a city which now has a population of 47,000, was established as the capital of New Brunswick in 1785. A surveyor named Dugald Campbell had considerable vision: working in the 1780s, he set aside land along the riverfront as green space, and established a pattern of development based on a street-grid. Several unrelated occurrences have recently provided the City of Fredericton with a unique opportunity to build upon the planning legacy established by Campbell.
