description: We analyze the Ericksen-Leslie system equipped with the Oseen-Frank energy in three space dimensions. Recently, the author introduced the concept of measure-valued solutions to this system and showed the global existence of these generalized solutions. In this paper, we show that suitable measure-valued solutions, which fulfill an associated energy inequality, enjoy the weak-strong uniqueness property, i. e. the measure-valued solution agrees with a strong solution if the latter exists. The weak-strong uniqueness is shown by a relative energy inequality for the associated nonconvex energy functional.

The decline of the urban horse in American cities
Creators: name: McShane, Clay
name: Tarr, Joel
Publisher: name: Carnegie Mellon University
Year: 2003
Subjects: History

description: Urban horses were phased out gradually, function by function, over the course of a century. Between 1850 and 1880 the number of urban horses grew dramatically, since most freight on the new railroad network required local delivery and rapidly growing cities required more passenger service. The displacement of the horse was slow: for stationary purposes beginning around 1830, for street railways from 1885 to 1895, for light passenger use from 1895 to 1915 and for heavy freight from 1915 to 1930. Equine technology, supposedly made obsolescent by the steam engine, showed remarkable resilience, persisting for more than a century after its supposed replacement.

Density Perturbations and the Cosmological Constant from Inflationary Landscapes

Year: 2005
Subjects: subject: High Energy Physics - Theory (hep-th)

subject: FOS: Physical sciences

description: An anthropic understanding of the cosmological constant requires that the vacuum energy at late time scans from one patch of the universe to another. If the vacuum energy during inflation also scans, the various patches of the universe acquire exponentially differing volumes. In a generic landscape with slow-roll inflation, we find that this gives a steeply varying probability distribution for the normalization of the primordial density perturbations, resulting in an exponentially small fraction of observers measuring the COBE value of 10^-5. Inflationary landscapes should avoid this "σproblem", and we explore features that can allow them to do that. One possibility is that, prior to slow-roll inflation, the probability distribution for vacua is extremely sharply peaked, selecting essentially a single anthropically allowed vacuum. Such a selection could occur in theories of eternal inflation. A second possibility is that the inflationary landscape has a special property: although scanning leads to patches with volumes that differ exponentially, the value of the density perturbation does not vary under this scanning. This second case is preferred over the first, partly because a flat inflaton potential can result from anthropic selection, and partly because the anthropic selection of a small cosmological constant is more successful.

description: A parameter-free evaluation of the $N - P_{11}(1440)$ electromagnetic transition form factors is performed within a light-front constituent quark model, using for the first time the eigenfunctions of a mass operator which generates a large amount of configuration mixing in baryon wave functions. A one-body electromagnetic current, which includes the phenomenological constituent quark form factors already determined from an analysis of pion and nucleon experimental data, is adopted. For $Q^2$ up to few $(GeV/c)^2$, at variance with the enhancement found in the elastic channel, the effect of configuration mixing results in a significant suppression of the calculated helicity amplitudes with respect to both relativistic and non-relativistic calculations, based on a simple gaussian-like ansatz for the baryon wave functions.

The City and Technology
Creators: name: Tarr, Joel
Publisher: name: Carnegie Mellon University
Year: 2005
Subjects: History

description: Historically, cities are a product of the interaction of technology and society, as a complex of tools and skills produced an economic surplus that permitted humans to live in non-agricultural settlements. Today, technology provides what might be called the “sinews” of the city: road, bridge and transit networks; water and sewer lines and waste disposal facilities; and power and communications systems. Other technologies, such as the streetcar, the subway, the motor truck and the automobile have provided mobility (and sometimes immobility) within the city and its region. Additional technologies have shaped the character of the built environment and the character of the cityscape. These technological systems made it possible for large numbers of residents to live in cities and also to increasingly separate work and residence. Technology facilitated city growth and diversification; over the course of two centuries it has caused profound changes in the patterns of urbanization in the United States and in the organization of urban society (Tarr and Dupuy 1988).

description: The ``in-in'' formalism is reviewed and extended, and applied to the calculation of higher-order Gaussian and non-Gaussian correlations in cosmology. Previous calculations of these correlations amounted to the evaluation of tree graphs in the in-in formalism; here we also consider loop graphs. It turns out that for some though not all theories, the contributions of loop graphs as well as tree graphs depend only on the behavior of the inflaton potential near the time of horizon exit. A sample one-loop calculation is presented.

description: More than a decade has now passed since Argentina gained international notoriety for defaulting on its crushing foreign debt. The convertibility plan, which had pegged the peso to the dollar at a 1-1 rate since 1991, collapsed in December of 2001 under the weight of its own non-sustainability. Skyrocketing unemployment and widespread poverty led to massive street protests on the 19th and 20th of that month, bringing an end to President De la Rúa’s Alianza government and, eventually, to the neoliberal economic model that it had inherited. In the years that followed, the country flourished, reducing social inequity and maintaining overall growth even during the ‘global’ economic crises that engulfed the United States and Europe a few years later. The case of Argentina has justly sparked renewed debate, particularly within Latin America, about the nature of the state and the feasibility of neoliberal economics. Questions as to the proper role of political direction in guiding economic policy have once again taken centre stage. Furthermore, the massive popular mobilization that spelled the ultimate end of neoliberalism’s legitimacy in Argentina is reflected in similar mobilizations within the Global North, as financial speculation and deregulation become increasingly identified as responsible for problems with the current economic system and its effects on those living within it. The protests that brought about such drastic change in Argentina were the product of a general dissatisfaction and frustration with political representatives and the failure of democracy to allow citizens the right of choice concerning economic policy. Yet at this critical juncture, it is worth noting that the protests were also fundamentally concerned with ideas of work, legality, moral obligation, and human dignity. Embedded in the many acts of protest and resistance that surrounded the Argentine crisis and its aftermath were discursive struggles over the nature of social life and the relationship of the state to society.
Probing the Origin of the EMC Effect via Tagged Structure Functions of the Deuteron

description: We demonstrate that measurement of tagged structure functions of the deuteron in (e,e'N) semi-inclusive reactions can discriminate between different hypotheses on the origin of the nuclear EMC effect. By choosing extreme backward kinematics for the spectator nucleon to minimize effects from the deuteron wave function and final state interactions, one can isolate the modifications in the structure of the bound nucleon within the impulse approximation. The same reaction can be used to extract the large-x neutron to proton structure function ratio.

description: Transient negative differential capacitance (NC), the dynamic reversal of transient capacitance in an electrical circuit is of highly technological and scientific interest since it probes the foundation of ferroelectricity. In this letter, we study a resistor-ferroelectric capacitor (R-FeC) network through a series of coupled equations based on Kirchhoff's law, Electrostatics, and Landau theory. We show that transient NC in a R-FeC circuit originates from the mismatch between rate of free charge change on the metal plate and that of bound charge change in a ferroelectric (FE) capacitor during polarization switching. This transient charge dynamic mismatch is driven by the negative curvature of the FE free energy landscape. It is also analytically shown that a free energy profile with the negative curvature is the only physical system that can describe transient NC during the two-state switching in a FE capacitor. Furthermore, this transient charge dynamic mismatch is justified by the dependence of external resistance and intrinsic FE viscosity coefficient. The depolarization effect on FE capacitors also shows the importance of negative curvature to transient NC. The relation between transient NC and negative curvature provides a direct insight into the free energy landscape during the FE switching.

description: The rheology of 2D steady surface flow of cohesionless cylinders in a rotating drum is investigated through {\em Non Smooth Contact Dynamics} simulations. Profile of volume fraction, translational and angular velocity, rms velocity, strain rate and stress tensor were measured at the midpoint along the length of the surface flowing layer where the flow is generally considered as steady and homogeneous. Analysis of these data and their inter-relations suggest the local inertial number - defined as the ratio between local inertial forces and local confinement forces - to be the relevant dimensionless parameter to describe the transition from the quasi-static part of the packing to the flowing part at the surface of the heap. Variations of the components of the stress tensor as well as the ones of rms velocity as a function of the inertial number are analysed within both the quasi-static and the flowing phases. Their implications are discussed.

Solidarity and Accountability: Rethinking Citizenship and Human Rights

Subjects: History

description: in July of 1999, a small nonprofit organization based in Buenos Aires brought a case against the state of Argentina in front of the InterAmerican Commission on Human Rights (IACHR), part of the Organization of American States.1 Comprised of family members of victims from the 1994 bombing of a local Jewish center, the group Memoria Activa, or Active Memory, accused the Argentine government of violating their human rights to justice and to the protection of their lives and physical integrity, for failing to prevent the attack or to bring its perpetrators to trial. Memoria Activa also expressed their demand for justice and full rights to security by holding weekly events in the public plaza facing the Justice Building (Palacio de Justicia). In doing so, they insisted that they were exercising their rights and performing their duties as citizens, asserting what the state’s role should be, and demanding that it meet its obligations. At the same time and also in Argentina, spiraling unemployment numbers brought about the emergence of the recuperated businesses movement. Driven in part by more than 5,000 factory business closures during the second half of the 1990s, the movement was formed by former employees of these bankrupt factories and businesses, who banded together as workers’ cooperatives and re-created the jobs that had just disappeared. In fighting for legal tenancy of the establishments they had put back into production, cooperative members demanded that the state give primacy to their human right to the means to earn a living and fulfill its role in protecting their rights as citizens to meaningful access to dignified work.
Science and the Death Penalty: DNA, Innocence, and the Debate over Capital Punishment in the United States
Creators: name: Aronson, Jay
name: Cole, Simon A.
Publisher: name: Carnegie Mellon University
Year: 2009
Subjects: History

description: The death penalty debate in the United States has recently undergone a fundamental shift. The possibility of executing the innocent has emerged as some abolitionists' most salient argument, displacing debates over such issues as fairness, deterrence, and cost. Innocence has managed to move to the fore of the debate in part because of the success of death penalty opponents in attaching epistemological certainty to one particular category of postconviction exonerations, those vouched for by the authority of DNA evidence. We suggest that such moves are primarily rhetorical because, while DNA evidence may be more accurate and reliable than other forensic science, it still fundamentally probabilistic in nature and is prone to uncertainties at all stages of its production. Yet, because of the certainty attached to DNA evidence in public discourse, it can be used as a lever with which to challenge law's claims to truth-making authority, and to undermine public trust in the death penalty. A few abolitionists and other scholars have expressed misgivings about the abolitionist embrace of the innocence argument. We push this concern further, suggesting that both abolitionists and death penalty reformers, who seek to promote a “scientific” death penalty centered on DNA evidence, draw upon a mythologized notion of “science” as a producer of epistemic certainty.

Ram pressure and turbulent/viscous stripping removes 100% of the atomic hydrogen content of luminous galaxies like the Milky Way within 100 million years. These mechanisms naturally account for the morphology of S0 galaxies, the rapid truncation of star formation implied by spectroscopic observations, as well as a host of observational data on the HI morphology of galaxies in clusters.

The Recontextualisation of Professional Ideas and Practices in Indonesian Primary Schools : A Case Study of the Alps (Active Learning Through Professional Support) Project
Creators: name: Belen, Sirilus.
Publisher: name: London South Bank University
Year: 1995

description: Educational innovation forms a major part of the educational transfer from developed to developing countries. In the case of Indonesia, between the 1970s and 1990s, western educational ideas and practices had a direct influence on the establishment of institutions, theories and practices of management, pedagogic practices, curriculum context and assessment. Relevant questions to be asked of this transfer are : Does it raise issues of value conflict between foreign and national values ? Do the transferred ideas and practices fit with the cultural structure into which they are introduced ? To what extent have they brought changes in the professional practices of teachers, headteachers and supervisors, and in the teaching-learning process, and - ultimately in enhancing pupil’s learning ? Such questions motivated the author to investigate the ALPS (Active Learning through Professional Support) Project. ALPS was a maior innovation in Indonesian primary schools, and had a great impact on a variety of educational components. The success witnessed during its initial stages was followed by a period of decline. Sustainability is a major concern, and many studies of school effectiveness are inadequate in explaining this phenomenon. Unfortunately, there is insufficient research on this issue in developing countries, particularly in relation to cultural perpectives - from teachers’ ideas and practices in their lives outside school, and how these are reflected in their practices within school. This led the author to examine the factors influencing the recontextualisation process of ALPS ideas and practices from a cultural perspective. "Text" in its extended sense refers to ideas and practices expected in the ALPS programme. The application of the "text" in different cultures leads us to the notion of "con-text". Clearly, the context of ALPS ideas and practices originating in the U.K. differs from the Indonesian context. To a certain extent, the project’s consultants, staff and educational authorities tried to make adaptations to the existing context. However, due to the project’s emphasis on local-based development, the introduction of new ideas and practices through learning-how-to-learn, and its subsequent implications for many aspects of school life, what occurred was not merely an adaptation but a re-contextualisation of existing contexts. Teachers and headteachers - the agents - applied recontextualising principles of delocating, relocating, appropriating, and refocusing ideas and practices, adapting them to their own context and situation.

description: The stable approximate solution of ill-posed linear operator equations in Hilbert spaces requires regularization. Tight bounds for the noise-free part of the regularization error are constitutive for bounding the overall error. Norm bounds of the noise-free part which decrease to zero along with the regularization parameter are called profile functions and are subject of our analysis. The interplay between properties of the regularization and certain smoothness properties of solution sets, which we shall describe in terms of source-wise representations is crucial for the decay of associated profile functions. On the one hand, we show that a given decay rate is possible only if the underlying true solution has appropriate smoothness. On the other hand, if smoothness fits the regularization, then decay rates are easily obtained. If smoothness does not fit, then we will measure this in terms of some distance function. Tight bounds for these allow us to obtain profile functions. Finally we study the most realistic case when smoothness is measured with respect to some operator which is related to the one governing the original equation only through a link condition. In many parts the analysis is done on geometric basis, extending classical concepts of linear regularization theory in Hilbert spaces. We emphasize intrinsic features of linear ill-posed problems which are frequently hidden in the classical analysis of such problems.

description: They saw it coming. Writers. The Revolution. Not in any prescient way nor with any real accuracy, and certainly not with any predictability (they were playwrights and poets, after all, not futurologists), but they sensed disquiet, heard the nearly inaudible harp strings of discord playing on the horizon, and picked up on what Bécquer would later so beautifully refer to as “los átomos del aire” (208). When the invasion finally came and the war broke out in 1808, that subtle disquiet turned into a maelstrom of noise, a chorus of voices singing out a harsh reality, mocking an untenable situation that they could not control—or rather, could only hope to control through the power of their words—, and seeking to shape a better future. And then, as suddenly as their voices were heard, they were silenced again, consigned to the basement of history (or to the footnotes of unread scholarship).

description: The present paper is concerned with investigating the capability of the smoothness preserving fictitious domain method from [22] to shape optimization problems. We consider the problem of maximizing the Dirichlet energy functional in the class of all simply connected domains with fixed volume, where the state equation involves an elliptic second order differential operator with non-constant coefficients. Numerical experiments in two dimensions validate that we arrive at a fast and robust algorithm for the solution of the considered class of problems. The proposed method keeps applicable for three dimensional shape optimization problems.
Solidarity in Our Experiences: A Qualitative Research Study Exploring Ways to Increase the Persistence of Black Female Principals of Secondary Charter Schools

description: This qualitative study investigates factors that influence the persistence of Black female principals of secondary charter schools. It examines the motivators that drive their commitment, the systems challenges that lead to thoughts of exiting their role, and recommendations for strategies that Charter Management Organizations (CMOs) can utilize to bolster their success and longevity. Through semi-structured interviews and a focus group, this research elevates the experiences of Black female principals, fostering a professional dialogue on the intersectionality of gender, race, age, and professional identity.Central findings indicate a strong sense of duty, responsibility, and dedication among Black female principals against systemic barriers undermining their well-being, leadership efficacy, and self-confidence. The necessity of self-advocacy and tailored organizational support emerges as a critical theme, pointing to the essential nature of work-life balance, manageable workloads, and organizational stability in nurturing the well-being and confidence of these leaders. From these findings, the study presents targeted recommendations for CMOs, including instituting mandatory remote workdays for principals to mitigate workload intensity, consistent and adequate time for new policy or initiative implementation, involving principals directly in decision-making processes, and acknowledgment of the complex and nuanced realities and challenges faced by Black female leaders. The study stresses the importance of systemic support structures like robust support networks, mentorship programs, and culturally relevant professional development.The research underscores the significant impact of Black female principals' voices and experiences in shaping their professional environments. It calls for all school systems, especially CMOs, to take proactive steps toward meeting their needs. This approach will benefit the leaders, their organizations, and the student communities they serve. Insights drawn from the stories of research study participants paired with the researcher’s analytical reflections emphasize the authentic experiences of Black female principals and call for organizational changes that support their longevity as principal leaders, leading to recommendations to CMOs that challenge them to make shifts in their policies and practice to better support the needs of Black female principals of secondary charter schools.

description: The general seven-dimensional maximal supergravity is presented. Its universal Lagrangian is described in terms of an embedding tensor which can be characterized group-theoretically. The theory generically combines vector, two-form and three-form tensor fields that transform into each other under an intricate set of nonabelian gauge transformations. The embedding tensor encodes the proper distribution of the degrees of freedom among these fields. In addition to the kinetic terms the vector and tensor fields contribute to the Lagrangian with a unique gauge invariant Chern-Simons term. This new formulation encompasses all possible gaugings. Examples include the sphere reductions of M theory and of the type IIA/IIB theories with gauge groups SO(5), CSO(4,1), and SO(4), respectively.

description: We introduce a simple method of analyzing the transitional dynamics of the Uzawa-Lucas endogenous growth model with human capital externalities. We use the value function approach to solve both the social planner's optimization problem in the centralized economy and the representative agent's optimization problem in the decentralized economy. The complexity of the Hamilton-Jacobi-Bellman equations is significantly reduced to an initial value problem for one ordinary differential equation. This approach allows us to find the optimal controls for the non-concave Hamiltonian in the centralized case and to identify the symmetric Nash equilibrium of the agents' optimal strategies in the decentralized case. For a wide range of the degree of the human capital externality we calculate the global transitional dynamics towards the balanced growth path. The U-shaped course of output growth rates is explained in detail. JEL Classifications: C61, O41, C72

description: We introduce the notion of the degree of ill--posedness of linear operators in operator equations between Hilbert spaces. For specific assumptions on the noise this quantity can be computed explicitely. Next it is shown that the degree of ill--posedness as introduced explains the loss of accuracy when solving inverse problems in Hilbert spaces for a variety of instances.

description: We study the Lang-Kobayashi model in the long-delay limit, focussing our attention on the stability properties of external cavity modes (ECMs) of this system. We show that ECMs can display different types of instabilities: strong instabilities and weak modulational-type instability. We explain the origin of these instabilities and show how they affect the complicated dynamics of the Lang-Kobayashi model.

description: Giant impacts have been suggested to explain various characteristics of terrestrial planets and their moons. However, so far in most models only the immediate effects of the collisions have been considered, while the long-term interior evolution of the impacted planets was not studied. Here we present a new approach, combining 3-D shock physics collision calculations with 3-D thermochemical interior evolution models. We apply the combined methods to a demonstration example of a giant impact on a Mars-sized body, using typical collisional parameters from previous studies. While the material parameters (equation of state, rheology model) used in the impact simulations can have some effect on the long-term evolution, we find that the impact angle is the most crucial parameter for the resulting spatial distribution of the newly formed crust. The results indicate that a dichotomous crustal pattern can form after a head-on collision, while this is not the case when considering a more likely grazing collision. Our results underline that end-to-end 3-D calculations of the entire process are required to study in the future the effects of large-scale impacts on the evolution of planetary interiors.

description: The purpose of this research effort is to examine the feasibility of designing a stated preference instrument to elicit the public’s willingness-to-pay (WTP) for remediation of leaking underground storage tank (LUST) sites (or perhaps prevention of releases). Nearly 500,000 releases have been documented from the over 600,000 USTs nationwide. Approximately 80 percent of these sites have been cleaned up. In the three Maryland counties that are the focus of this and the companion hedonic property value study there have been nearly 400 documented releases in the last 10 years. We report the results from four focus groups and four three-on-one interviews conducted in Maryland. The results of this focus group research provide a foundation for development of a stated preference study of the benefits of EPA’s UST program.

description: The effect of sequence heterogeneity on the dynamics of molecular motors is reviewed and analyzed using a set of recently introduced lattice models. First, we review results for the influence of heterogenous tracks such as a single-strand of DNA or RNA on the dynamics of the motors. We stress how the predicted behavior might be observed experimentally in anomalous drift and diffusion of motors over a wide range of parameters near the stall force and discuss the extreme limit of strongly biased motors with one-way hopping. We then consider the dynamics in an environment containing a variety of different fuels which supply chemical energy for the motor motion, either on a heterogeneous or on a periodic track. The results for motion along a periodic track are relevant to kinesin motors in a solution with a mixture of different nucleotide triphosphate fuel sources.

Poisson convergence in the restricted k-partioning problems

description: The randomized $k$-number partitioning problem is the task to distribute $N$ i.i.d. random variables into $k$ groups in such a way that the sums of the variables in each group are as similar as possible. The restricted $k$-partitioning problem refers to the case where the number of elements in each group is fixed to $N/k$. In the case $k=2$ it has been shown that the properly rescaled differences of the two sums in the close to optimal partitions converge to a Poisson point process, as if they were independent random variables. We generalize this result to the case $k>2$ in the restricted problem and show that the vector of differences between the $k$ sums converges to a $k-1$-dimensional Poisson point process.
Comment on 'Radiative transfer in CO2-rich atmospheres: 1. Collisional line mixing implies a colder early Mars'

description: Ozak et al. [2016] claimed that explicitly including the effect of CO$_2$ collisional line mixing (LM) in their radiative transfer calculations yield CO$_2$ atmospheres that are more transparent to infrared radiation than when spectra calculations are made using sub-Lorentzian line shapes. This would in particular imply significantly colder surface temperatures (up to 15K) for early Mars than estimated in previous studies. Here we show that the relative cooling that Ozak et al. [2016] associated to the effect of collisional line mixing is in fact due to a wrong choice of broadening species (air instead of CO$_2$). We then calculated Line-by-Line spectra of pure CO$_2$ atmospheres using a line-mixing model developed for self-broadened CO$_2$. Using the LMD Generic model (in 1D radiative-convective mode), we find that calculations made with the proper collisional line mixing model and with sub-Lorentzian line shapes lead to differences between early Mars surface temperatures smaller than 2 Kelvins only.

description: Finding an appropriate way to incorporate environmental justice considerations into policymaking has been a procedural challenge since President Clinton issued Executive Order 12,898 over 15 years ago. Moreover, environmental justice continues to be overshadowed by efficiency considerations as embodied in benefit-cost analysis. This article argues that the environmental justice and benefit-cost policies and procedures in EPA's rule-making can both be improved by bringing them closer together, ultimately improving environmental regulations as well. In particular, environmental justice consideration should be incorporated into Regulatory Impact Analyses (RIAs) by drawing on the much older tradition of incorporating distributional effects into benefit-cost analysis. By providing information on the distribution of benefits and costs of its regulatory actions, EPA would further its environmental justice objectives by providing the information that all groups—including the poor, minorities, and environmental justice communities—need to understand the impacts of a regulatory action. By incorporating such information into its RIAs, EPA would integrate environmental justice considerations into its development of regulations. Finally, by actually allowing the new information to inform the design and selection of regulations so as to better protect disadvantaged groups, adding distributional impacts to RIAs would improve the distributive justice associated with EPA's actions as well as the procedural justice.

Pittsburgh as an Energy Capital: Perspectives on Coal and Natural Gas Transitions and the Environment

description: Throughout most of its history Pittsburgh has been closely identified with the fossil fuel coal as a source of both industrial progress and of environmental degradation. Located on top of the high-quality Pittsburgh bituminous coal seam, the city’s businesses, industries, residents, railroads, and steamboats benefited from the high-energy and easily available fuel. Coal has shaped the pattern of industrial development, settlement, population, and labor force composition. Its mining and consumption also drove the environmental contamination and physical alteration of land and water, as well as seriously polluting the air. Without coal and the advantages of its location, Pittsburgh would not have become one of the world’s great industrial powers in the late nineteenth and early twentieth centuries.1 The tentacles of the city’s industrial and financial interests and its ecological footprint spread throughout the region, tying its hinterland ever closer to the city
