Playing Around with Civic Engagement Strategies in the Triad
Creators: name: Ryan, Deborah

Year: 2014

description: In the 1989 film Field of Dreams, Kevin Costner plays the owner of a failing farm, who hears a voice repeatedly whisper, “If you build it, he will come” as he walks through his cornfield. Costner eventually learns “it” is a baseball field and that the “he” is the long-deceased Shoeless Joe Jackson and seven other equally dead baseball players banned from the sport in the 1919 “Chicago Black Sox” scandal. Costner plows down the cornfield, the players arrive, and his farm is supposedly saved by the hundreds of people seen approaching in cars to watch the game at the end of the film. But urban planning is not Field of Dreams. Planners and leaders should understand that when it comes to public meetings, even “If you build it,” it is unlikely the public “will come” to save the farm, or show up to share their thoughts about how growth should occur on or around it.

description: The supersymmetric type II seesaw may leave a limit where a triplet boson along with the standard Higgs boson remains light. Working in this limit with small triplet vacuum expectation vlaues, we explore how much such a light triplet boson can contribute to the Higgs boson decay to diphoton, and analyze the feasibility to observe it through same-sign di-lepton and tetra-lepton signals in the forthcoming LHC run after setting a LHC7 limit in a simplified parameter space of the triplet vaccum expectation value and the doubly charged boson mass.

Should North Carolina Cities be Required to Have a Housing Element?
Creators: name: Stowell, Candace H.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2008

description: One strategy to promote affordable housing is for the state legislature to mandate that local governments make provisions for more low-cost units. Many states have passed laws requiring towns and cities to inventory their housing stock and carry out plans to correct imbalances. Candace Stowell discusses the lack of such legislation in North Carolina as well as numerous examples of housing elements that have been implemented by other states.

Planning as an Historic Resource: An Example from the Western Piedmont of North Carolina
Creators: name: Hartley, Michael O.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1993

description: As an archaeologist working with the historic resources of Carolina for more than twenty years I have found that the issues of planning have been an ever-present consideration in the study of our culture. It might be thought that this refers to the interface between the archaeologist or preservation planner and twentieth century change. It may also refer to the destruction of historically significant material resources, for example the excavation of a plantation ruin in the path of a bypass around Charleston or the clearance of a reservoir basin on one of our river systems. There is, however, a broader aspect to the approach of archaeology: the ability of the discipline to examine process over time and determine the relationship of one point in time to another in terms of process. It is that aspect of the archaeological analysis of Carolina that this discussion will treat. In particular, it is intended here to examine the presence of planning in the origins of Carolina, in the origins of the Moravian towns of western North Carolina, and to draw some conclusions about the effect of that planning in the present day. Planning is a basic historic artifact of Carolina, an artifact which is visible in its material structure and in the ongoing flow of its culture. As current planning takes place it is important to be aware that processes begun generations before continue into the present. As never before we have the capability to irrevocably transform the configuration of our landscape and in that process alter the streams of our culture. As our rate of change accelerates and our ability to affect physical change intensifies, it is important to recognize and enhance what is already present.

description: Some features of the physics of radiation-dominated shock waves are discussed with emphasis on the peculiarities which are important for correct numerical modeling of shock breakouts in supernova. With account of those peculiarities, a number of models for different supernova types is constructed based on multigroup radiation transfer coupled to hydrodynamics. We describe the implementation of a new algorithm RADA, designed for modeling photon transfer at extremely-relativistic motions of matter, into our older code STELLA. The results of numerical simulations of light curves, and continuum spectra are presented. The influence of effects of photon scattering on electrons, of thermalization depth and of special relativity in transfer equation is considered. Some cases are demonstrated, when the appearance of hard X-ray emission is possible at the shock breakout. The necessary refinements in numerical algorithms for radiative transfer and hydrodynamics are pointed out. Prospects for using the results of numerical simulation to analyze and interpret available and future data from space observatories are discussed.

description: Maleidrides are a class of bioactive secondary metabolites unique to filamentous fungi, which contain one or more maleic anhydrides fused to a 7-, 8- or 9- membered carbocycle (named heptadrides, octadrides and nonadrides respectively). Herein structural and biosynthetic studies on the antifungal octadride, zopfiellin, and nonadrides scytalidin, deoxyscytalidin and castaneiolide are described. A combination of genome sequencing, bioinformatic analyses, gene disruptions, biotransformations, isotopic feeding studies, NMR and X-ray crystallography revealed that they share a common biosynthetic pathway, diverging only after the nonadride deoxyscytalidin. 5-Hydroxylation of deoxyscytalidin occurs prior to ring contraction in the zopfiellin pathway of Diffractella curvata. In Scytalidium album, 6-hydroxylation-confirmed as being catalysed by the α-ketoglutarate dependent oxidoreductase ScyL2-converts deoxyscytalidin to scytalidin, in the final step in the scytalidin pathway. Feeding scytalidin to a zopfiellin PKS knockout strain led to the production of the nonadride castaneiolide and two novel ring-open maleidrides. © The Royal Society of Chemistry.
Making the Brownfield-Transportation Link: Smart Growth Options for States and Metropolitan Areas

Year: 2001

description: A decade ago, passage of the Intermodal Surface Transportation Efficiency Act of 1991 (ISTEA) marked a turning point in transportation policy. ISTEA gave states and metropolitan areas much-needed flexibility to set their own transportation funding priorities; it also encouraged them to pursue their transportation goals in concert with community and environmental goals. ISTEA and its successor, the Transportation Equity Act for the 21st Century (TEA-21), have opened up opportunities to coordinate transportation planning and community land use planning—which for much of the post- World War II period took place in separate spheres. Some states have run with these new options, creating not only improved transportation efficiency, but also redeveloping browntlelds and reaping economic, community, and environmental benefits linked to smart growth.
Teaching Kids About Planning

Year: 1996

description: Every planner has probably given some thought to teaching kids about planning, and some have had the opportunity to do this from time to time during their professional careers. Many of us have been asked by a classroom teacher in our community to tell students about what we do on the job. Some of us may have been given opportunities to go further and teach about specific elements of our profession. Hopefully, this report will instill an added desire to get into the classroom and teach the future generation about planning. In this article. I hope to: 1) Encourage planners to teach kids about our profession and how it impacts society, 2) Provide a brief overview of the American Planning Association's efforts to teach kids about planning, 3) Explain recent and past efforts by the North Carolina Chapter of the American Planning Association (NCAPA) to teach kids about planning, including efforts of NCAPA to establish a planning exhibit at Discovery Place in Charlotte, 4) Provide a partial listing of resources available for teaching kids about planning, and 5) Suggest ideas on how to get the most out of a classroom visit, for you the planner as well as the students.

description: An accurate risk assessment for fatigue damage is of vital importance for the design and service of today's turbomachinery components. We present an approach for quantifying the probability of crack initiation due to surface driven low-cycle fatigue (LCF). This approach is based on the theory of failure-time processes and takes inhomogeneous stress fields and size effects into account. The method has been implemented as a finite-element postprocessor which uses quadrature formulae of higher order. Results of applying this new approach to an example case of a gas-turbine compressor disk are discussed.

It has also significantly changed the set of skills that entry level planners are expected to possess.

We have examined the experimental data available in literature and we have found out that it is possible to reproduce the experimental critical temperature, the gap values and the upper critical magnetic field within an effective model in moderate strong-coupling regime that must include both an intraband term $λ_{11}\sim0.9$ and an interband spin-fluctuations ($λ_{tot}^{sf}\sim1.5$) coupling. The presence of a non negligible intraband coupling can be a fictitious effect of the violation of Migdal's Theorem.

Across oceans and campuses: HBCU presidents and the search for democratic ideas abroad in the early-mid 20th century
Creators: name: O'Connor, Molly Elizabeth
Publisher: name: No Publisher Supplied
Year: 2023

description: Because the legacies of America’s racial apartheid continue to shape the educational and political landscape today, we must examine how American institutions of higher education have historically shaped students’ ideas about citizenship, democracy, and equality. Current scholarship chronicles the impact of Black internationalism on domestic affairs in political and religious arenas—but it leaves out the ways in which Black institutions of higher education and its leaders participated in the international transmission of alternative political ideas and were co-creators in the making of a global, African diasporic identity. In this dissertation, I analyze the ideas of Mordecai Johnson of Howard University, Benjamin Mays of Morehouse College, and Willa Player of Bennett College, who were deeply influenced by international, anticolonial, and non-violence movements. I argue that their global travels, ideas, and networks ultimately influenced their leadership of Black colleges. The resulting global vision was critical to the role college presidents and Historically Black Colleges and Universities (HBCUs) played in dismantling Jim Crow. As the realization of democratic ideals continues to be illusive for many groups of Americans, and the world becomes increasingly globalized, this research provides practical arguments for educational leaders who can think beyond their own context and toward a better future for their students. In addition to adding education to the broader conversation on Black internationalism and bringing insights about Black internationalism to analyses of higher education, this work challenges colleges and universities to take notice of the key role that international experiences play in the curriculum—and the high stakes consequences of parochialism. As educational institutions go about answering the question of how to incorporate intellectual and active social justice education into their curriculum, this dissertation compels administrators to reflect practically on (1) how leaders in higher education might be aware of and use their influence, (2) how to expand access to international opportunities for students on campus, and (3) how to incorporate more global perspectives in university academic departments.
Designing a Robust and Versatile System to Investigate Nutrient Exchange in, and Partitioning by, Mycorrhiza (Populus x canesces x Paxillus involutus) Under Axenic or Greenhouse Conditions

description: Phosphorus (P) bioavailability affects plant nutrition. P can be present in soils in different chemical forms that are not available for direct plant uptake and have to be acquired by different mechanisms, representing different resource niches. These mechanisms, of which many seem to be attributed to mycorrhiza, likely influence the diversity and stability of plant communities in natural ecosystems, as they also might help to overcome a future shortage of P supply in agro-ecosystems. In order to understand the mechanisms of P acquisition, the associated carbon costs, and the resource partitioning by mycorrhizal fungi, the ecosystem situation has to be mimicked in smaller scaled experiments. Here, different experimental setups are evaluated using plantlets of Populus x canescens and its functional ectomycorrhizal (ECM) fungus Paxillus involututs strain MAJ. To investigate resource partitioning involving mycorrhizae, the protocols of this study describe preparation of an in vitro and a rhizotrone culture systems for studies under axenic conditions as well as a mesocosm culture system for greenhouse conditions. We also describe the construction of separate compartments containing nutrients and excluding plant roots as well as the progress that has been made in in vitro propagation of plant and ECM fungal material. The practical experience made in our study shows that the in vitro culture system is prone to desiccation and its construction and maintenance are more time consuming and complicated. In contrast, with the axenic rhizotrone culture system and the mesocosms we have created more robust and very versatile systems that are also suitable for greenhouse conditions.

description: We report a kind of quantum phase transition which takes place in isolated quantum systems with non-thermal equilibrium states and an extra symmetry that commutes with the Hamiltonian for any values of the system parameters. A critical energy separates two different phases, one in which the symmetry is broken. This critical behavior is ruled out as soon as the system is put in contact with a thermal bath. The critical point is crossed when a sufficent amount of work is performed on the system, keeping it isolated from the environment. Different phases are identified by means of an order parameter, which is only different from zero in the symmetry-breaking phase. The behavior of the system near the critical point is determined by a set of critical exponents. We illustrate this phenomenon by means of numerical calculations in three different two-level systems.

description: In der Sammlung des Archäologischen Museums Frankfurt a.M. befinden sich Klinenfragmente, die im 19. Jahrhundert zu einem Bisellium zusammengesetzt wurden. Die Hintergründe solch fehlerhafter Rekonstruktionen von Klinenfragmenten zu Bisellia werden auch anhand von Vergleichsobjekten beleuchtet. Das Frankfurter Objekt wird im Detail vorgestellt und beinhaltet die Sammlungsund Restaurierungsgeschichte, die Demontage in die einzelnen
Klinenelemente sowie Beobachtungen und naturwissenschaftliche Untersuchungen zur Technologie und Herstellungstechnik. Dabei wurde der dunklen Patina der
Bronzeoberflächen sowie den Verzierungen aus Silberund Kupfertauschierungen besondere Aufmerksamkeit gewidmet. Es gibt Hinweise auf ein bisher unbekanntes Herstellungsverfahren der Tauschierungen, das auf der
Granulationstechnik beruhen könnte.
description: Bed fragments in the collection of the Archaeological Museum in Frankfurt a. M., Germany, were assembled as a chair, a so-called bisellium, in the 19th century. Background information on such incorrect reconstructions is given, including
similar objects in other collections. The Frankfurt object is presented in detail with its collection and restoration- conservation history, the disassembly, as well as observations and scientific investigations concerning its manufacture. The dark patina on the bronze surface and the decorative silver and copper inlays are of special interest. Presumably, a sulfide patina was intentionally applied to the bronze surface by a brush or similar tool before the silver and copper were inlaid. The examination of the silver and copper inlays themselves suggests an unusual and so far unknown manufacturing method related to the granulation technique.

description: The rapid growth of marine aquaculture around the world accentuates issues of sustainabil-ity and environmental impacts of large-scale farming systems. One potential mitigation strategy is to relocate to more energetic offshore locations. However, research regarding the forces which waves and currents impose on aquaculture structures in such conditions is still scarce. The present study aimed at extending the knowledge related to live blue mussels (Mytilus edulis), cultivated on dropper lines, by unique, large-scale laboratory experiments in the Large Wave Flume of the Coastal Research Center in Hannover, Germany. Nine-months-old live dropper lines and a surrogate of 2.0 m length each are exposed to regular waves with wave heights between 0.2 and 1.0 m and periods between 1.5 and 8.0 s. Force time histories are recorded to investigate the inertia and drag characteristics of live mussel and surrogate dropper lines. The surrogate dropper line was developed from 3D scans of blue mussel dropper lines, using the surface descriptor Abbott–Firestone Curve as quality parameter. Pull-off tests of individual mussels are conducted that reveal maximum attachment strength ranges of 0.48 to 10.55 N for mussels that had medium 3.04 cm length, 1.60 cm height and 1.25 cm width. Mean drag coefficients of CD = 3.9 were found for live blue mussel lines and CD = 3.4 for the surrogate model, for conditions of Keulegan–Carpenter number (KC) 10 to 380, using regular wave tests. © 2020 by the authors.

Year: 2014

description: This study investigates potential economic effects of bikesharing, with a focus on local businesses and the neighborhood level, and highlights a potential area of collaboration between transportation planners and economic developers. This study makes a unique contribution by surveying users at bikeshare stations about intended spending related to the bikeshare trip as well as businesses located adjacent to those same stations about perceived spending by bikeshare users at those businesses. Using a sample of five Capital Bikeshare stations in Washington, DC, we conducted an intercept survey of 333 users at each of the stations and a doorto- door survey of 140 local businesses within 0.1 miles of the stations. We found that riders are motivated to use the system due to travel time (73%) and cost (25%) savings. In addition, 16% of riders report making new trips because of Capital Bikeshare. Meanwhile, 23% of users reported spending more money because they used bikeshare. We found that 20% of the businesses in our sample report a positive impact on sales, and 70% identify a positive impact on the neighborhood. Our findings suggest bikesharing may generate shared benefits among users and businesses relating to new trips and new spending.

description: The present study is dedicated to the microstructure characterization of the as-cast high entropy intermetallics that undergo a martensitic transformation, which is associated with the shape memory effect. It is shown that the TiZrHfCoNiCu system exhibits strong dendritic liquation, which leads to the formation of martensite crystals inside the dendrites. In contrast, in the CoNiCuAlGaIn system the dendritic liquation allows the martensite crystals to form only in interdendritic regions. This phenomenon together with the peculiarities of chemical inhomogeneities formed upon crystallization of this novel multicomponent shape memory alloys systems will be analyzed and discussed.

description: Aeroelasticity is one of the biggest challenges in wind turbine rotor design, as the length of rotor blades increases which comes along with a slenderer design. The knowledge of the aeroelastic turbine behavior is of great importance. A comparison to field measurements is of huge importance when validating aeroelastic tools. However, the measurement of deformation and torsion in the field is not trivial and the conduction of realistic post-test simulations is a challenge. One crucial factor for these simulations is the wind field, which needs to be captured in a high spatial and temporal resolution. In this paper, the results of deformation measurements conducted in the field with an optical measurement method called Digital Image Correlation (DIC) on one rotor blade will be shown and compared to aeroelastic post-test simulations using highly resolved wind fields measured with a SpinnerLidar. © 2020 Published under licence by IOP Publishing Ltd.

description: Based on the drive signals of a milling center, process forces can be reconstructed. Therefore, a novel approach is presented to reconstruct the process forces with a long short-term memory neural network (LSTM) using drive signals as an input. The LSTM is evaluated and compared to a model-based approach. The latter compensates nonlinearities and disturbances such as friction and inertia. For training of the LSTM, multiple milling processes are considered to enhance the generalizability. Training data is generated by recording drive signals and process forces measured by a dynamometer. The LSTM is then evaluated using a test set, which comprises new process parameters. It is shown that the LSTM has a lower root mean square error (RMSE) in comparison to the model-based approach. Especially, when changing the feed motion direction during milling, the neural network clearly outperforms the model-based approach. Nevertheless, there are processes, where the LSTM induced oscillations, which do not correspond to the measured forces. © 2020 MDPI Multidisciplinary Digital Publishing Institute.

description: A rigorous proof is presented of the boundedness of the entanglement entropy of a block of spins for the ground state of the one-dimensional quantum Ising model with sufficiently strong transverse field. This is proved by a refinement of the stochastic geometric arguments in the earlier work by Grimmett et al. (J Stat Phys 131:305–339, 2008). The proof utilises a transformation to a model of classical probability called the continuum random-cluster model. Our method of proof is fairly robust, and applies also to certain disordered systems. © 2019, The Author(s).
