The Changing Values of Learning: Comprehensive Planning in White Plains and Westchester County, NY

Subjects: City planning

description: Municipalities create comprehensive plans to provide a long-­‐term vision for growth and development and to determine the strengths and opportunities that will assist them in instituting ordinances and make future planning decisions. The New York Department of State indicates that comprehensive planning at the municipal level should provide a variety of goals and objectives that include both the intermediate and long-­‐range time period. Scholars believed that comprehensive planning “would have little effect on American cities unless their goal premises can be established in sufficiently compelling fashion (both politically and intellectually) to make politicians take notice” (1965). New York State law requires local zoning to be “in accordance with comprehensive plans” but does not mandate their implementation. The State legislature’s encouragement to prepare and adopt comprehensive plans has been effective; 70% of municipalities with planning board  in New York State have adopted a plan. County governments and non-­‐for-­‐profits are also developing comprehensive regional plans that are designed to guide decisions at both the municipal and regional levels. With so many plans and policies guiding an area, do the values of a local municipality match those at the county and regional levels? The methodology for approaching this question is a qualitative review of comprehensive plans created during the second half of the twentieth century. The City of White Plains provides an opportunity to evaluate how the values of a small suburban city that has undertaken multiple comprehensive plan initiatives relate to the planning values of Westchester County. Through an investigation of the past three comprehensive plans by the City of White Plains and the Westchester County Planning Board, this thesis will determine how values and initiatives are represented between the corresponding plans and whether comprehensive planning successfully addresses perennial planning initiatives and concerns.

description: The generalized amplitude damping channel (GADC) is one of the sources of noise in superconducting-circuit-based quantum computing. It can be viewed as the qubit analogue of the bosonic thermal channel, and it thus can be used to model lossy processes in the presence of background noise for low-temperature systems. In this work, we provide an information-theoretic study of the GADC. We first determine the parameter range for which the GADC is entanglement breaking and the range for which it is anti-degradable. We then establish several upper bounds on its classical, quantum, and private capacities. These bounds are based on data-processing inequalities and the uniform continuity of information-theoretic quantities, as well as other techniques. Our upper bounds on the quantum capacity of the GADC are tighter than the known upper bound reported recently in [Rosati et al., Nat. Commun. 9, 4339 (2018)] for the entire parameter range of the GADC, thus reducing the gap between the lower and upper bounds. We also establish upper bounds on the two-way assisted quantum and private capacities of the GADC. These bounds are based on the squashed entanglement, and they are established by constructing particular squashing channels. We compare these bounds with the max-Rains information bound, the mutual information bound, and another bound based on approximate covariance. For all capacities considered, we find that a large variety of techniques are useful in establishing bounds.

description: This dissertation offers an ethnographic account of the contemporary relationships between livelihood practices and food among the Tsimané Indians of the Bolivian Amazon. Because of the multitudinous properties of food, I use it as both a tool and a metaphor to focus my discussion on how a history of development in the region coalesces into new constructions of identity, values, practices, and knowledge for the Tsimané. Through a framework of `localized' modernity, I argue that food and food related processes are not only shaped by broad and indirect forms of development over time, but that they moderate them by formulating the ways in which they take root in everyday life. Understanding contemporary articulations of indigenous identity and cultural constructions is increasingly important to small lowland indigenous groups throughout Latin America, but particularly in Bolivia, where indigenous groups are engaging in new claims over autonomy, land, and resource rights as part of a new "plurinational" state. By offering insight into contemporary indigenous practices and knowledge, I draw attention to the ways politicized ideals of indigeneity in Bolivia can conflict with local ontologies. Based on over a year of fieldwork, the dissertation is organized into two sections. The first section examines a century of regional shifts that transformed the landscape in which the Tsimané historically reside along with their ability to survive solely from subsistence activities. I situate contemporary forms of livelihood production, specifically logging, within this history in order to highlight how past experiences transform local articulations of the emerging national indigenous and environmental politics of 'Vivir Bien'. The second section focuses specifically on livelihoods and food. I call attention to the ways global, national, and regional processes are experienced, interpreted, and transformed on a local level and through time. I illustrate this in three ways: first, through a discussion of time allotment and the relationship between subsistence activities and cash accruing activities; second, through a comparison of how people think about the domain of food and how they consume food; and lastly, through a discussion of one of the most important cooked foods of the Tsimané, Shocdye (beer), and the ways in which changing livelihood activities, conceptions of dietary practice, and social relationships and roles coalesce through cooking and eating.

description: Child-friendly City is quite a new planning concept in China that did not really arise until the 2010s. In recent years, many Chinese cities released their Child-friendly City Strategic Planning which highlighted the children’s right, growth, and opportunities and started to apply the concept into practice in planning projects. This study illustrates knowledge of child-friendly city planning by discussing the current child-friendly planning policies in Beijing and using Shuangjing Community as a case study to analyze children’s participation in the planning process. Interviews are made with different stakeholders, which help identify the community engagement plan involved, examine children’s roles and positions, and investigate their interactions. Finally, a couple of recommendations are proposed for a better child-friendly Beijing.
Models with symmetry-breaking phase transitions triggered by dumbbell-shaped equipotential surfaces
Creators: name: Baroni, Fabrizio
Publisher: name: arXiv
Year: 2019
Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)
subject: FOS: Physical sciences

description: In some recent papers some sufficiency conditions for the occurrence of a $\mathbb{Z}_2$-symmetry breaking phase transition ($\mathbb{Z}_2$-SBPT) have been showed starting from geometric-topological concepts of potential energy landscapes. In particular, a $\mathbb{Z}_2$-SBPT can be triggered by double-well potentials, or in an equivalent way, by dumbbell-shaped equipotential surfaces. In this paper we introduce two models with a $\mathbb{Z}_2$-SBPT which, due to their essential feature, show in the clearest way the generating-mechanism of a $\mathbb{Z}_2$-SBPT above mentioned. These models, despite they cannot be considered physical models, have all the features of such models with the same kind of SBPT. At the end of the paper, the $ϕ^4$ model is revisited in the light of this approach. In particular, the landscape of one of the model introduced here is turned out to be equivalent to that of the mean-field $ϕ^4$ model in a simplified version.
Applications of Geomorphology in Mine Reclamation
Creators: name: Myers, Kenneth
Publisher: name: The University of British Columbia
Year: 2024

description: The principals of both process geomorphology and fluvial geomorphology have broad application in mine reclamation. Geomorphology is the study of the landforms we see on the surface of the earth and the processes that create and sustain them, while fluvial geomorphology focuses specifically on the processes that involve the movement of water and sediment and the features and landforms that they create. Concepts like dynamic equilibrium, slope evolution, basin morphometry and drainage networks, sediment transport, grade control, and armour formation are some of the geomorphic approaches that can be used to mitigate some of the common problems and failure mechanisms encountered in the reclamation of mining facilities (including waste rock storage facilities, heap leach pads, tailings storage facilities, diversion channels, and impacted streams). Application of these techniques typically promotes a higher level of sustainability and reduced maintenance cost. This paper will illustrate where and how these techniques can be applied through the use of actual examples and case histories.

These identities have an elementary proof, and imply the "sum theorem" for multiple zeta values. They also have a succinct statement in terms of "cyclic derivations" as introduced by Rota, Sagan and Stein. In addition, we discuss the expression of other relations of multiple zeta values via the shuffle and "harmonic" products on the underlying vector space H of the noncommutative polynomial ring Q, and also using an action on Q of the Hopf algebra of quasi-symmetric functions.

We further prove that, for for all natural numbers $p$ and $r$, the vertices of every $r$-edge-coloured complete graph can be partitioned into a bounded number of $p$-th powers of cycles, settling a problem of Elekes, Soukup, Soukup and Szentmiklóssy. In fact we prove a common generalisation of both theorems which further extends these results to all host hypergraphs of bounded independence number.

description: The spatial gradient expansion of the generating functional was recently developed by Parry, Salopek, and Stewart to solve the Hamiltonian constraint in Einstein-Hamilton-Jacobi theory for gravitationally interacting dust and scalar fields. This expansion is used here to derive an order-by-order solution of the Hamiltonian constraint for gravitationally interacting electromagnetic and scalar fields. A conformal transformation and functional integral are used to derive the generating functional up to the terms fourth order in spatial gradients. The perturbations of a flat Friedmann-Robertson-Walker cosmology with a scalar field, up to second order in spatial gradients, are given. The application of this formalism is demonstrated in the specific example of an exponential potential.

The Chill of Fear: Can Experiencing Fear Affect Both Our Judgments of Ambient Temperature and Our Physical Skin Temperature?

Publisher: name: Columbia University
Year: 2011
Subjects: subject: Psychology
subject: FOS: Psychology

description: "It was a chilling account" is one of many metaphors using cold temperature terminology to describe fearful situations. The present study sought to explore whether or not these metaphors reflect psychological (a change in the perception of one's surroundings) and/or physiological (changes in skin temperature) experiences during a fear-inducing event. In this study participants were presented with emotion inducing stimuli designed to elicit a change in their subjective ambient temperature estimates as well as their skin temperature measurements. Before stimulus presentation, participants in this study were asked to provide their initial estimate of the ambient temperature of the testing room. They then watched a video clip showing fear-inducing, neutral or safety-inducing material and were then again asked to estimate the ambient temperature of the room. Throughout the duration of each session, participants' forehead skin temperature was continuously monitored using a skin temperature probe. Across the three conditions (fear, neutral, and safety) participants' subjective estimates of ambient temperature did not change significantly from before stimulus presentation to after stimulus presentation. In the fear condition, however, there was a non-significant trend in the predicted direction. Alternatively, skin temperature measurements did change significantly from baseline measures to measures taken during stimulus presentation, but no interaction effect of the before vs. after periods by the three conditions was observed. These results suggest that more research is needed to determine whether or not metaphors relating cold and fear are simply linguistic devices or reflections of the body and mind's experiences during a fearful experience.

description: Local Hamiltonians arise naturally in physical systems. Despite its seemingly `simple' local structure, exotic features such as nonlocal correlations and topological orders exhibit in eigenstates of these systems. Previous studies for recovering local Hamiltonians from measurements on an eigenstate $|ψ\rangle$ require information of nonlocal correlation functions. In this work, we develop an algorithm to determine local Hamiltonians from only local measurements on $|ψ\rangle$, by reformulating the task as an unconstrained optimization problem of certain target function of Hamiltonian parameters, with only polynomial number of parameters in terms of system size. We also develop a machine learning-based-method to solve the first-order gradient used in the algorithm. Our method is tested numerically for randomly generated local Hamiltonians and returns promising reconstruction in the desired accuracy. Our result shed light on the fundamental question on how a single eigenstate can encode the full system Hamiltonian, indicating a somewhat surprising answer that only local measurements are enough without additional assumptions, for generic cases.

The Chinese Revolution on the Tibetan Frontier: State Building, National Integration and Socialist Transformation, Zeku (Tsékhok) County, 1953-1958
Creators: Weiner, Benno Ryan
Publisher: name: Columbia University
Year: 2012
Subjects: History

description: This dissertation analyzes early attempts by the Chinese Communist Party to integrate Zeku (Tsékhok) County, an ethnically Tibetan, pastoral region located in southeastern Qinghai/Amdo, into the People's Republic of China.  Employing county-level archival materials, it argues that during the immediate post-Liberation period, Party leaders implicitly understood both the administrative and epistemological obstacles to transforming a vast multiethnic empire into a unitary, socialist nation-state. For much of the 1950s it therefore employed a "subimperial" strategy, referred to as the United Front, as a means to gradually and voluntarily bridge the gap between empire and nation. However, the United Front ultimately lost out to a revolutionary impatience that demanded immediate national integration and socialist transformation, leading in 1958 to communization, democratic reforms and rebellion.  Despite successfully identifying the tensions between empire and nation, and attempting to creatively resolve them, empire was eliminated before the process of de-imperialization and nationalization was completed.  This failure occurred at both the level of policy and narrative, leaving Amdo's Tibetan population unevenly absorbed into the modern Chinese nation-state.
The Chiral and U(1)_A Symmetries of the QCD Phase Transition using Chiral Lattice Fermions

description: With regard to the nature of the finite-temperature QCD phase transition and the fate of the chiral and anomalous axial symmetries associated with it, we present in this thesis two parallel sets of investigations into the QCD phase transition region between 139 and 195 MeV. Both studies adopt the Iwasaki gauge action augmented with the dislocation suppression determinant ratio with 2+1 flavors of chiral fermions. This choice of lattice action accurately reproduces the SU(2)_L × SU(2)_R and U(1)_A symmtries of the continuum.
      The first study simulates QCD thermodynamics on a line of constant physics that represents 200 MeV pions and physical kaons using domain wall fermions (DWF) at three space-time volumes: 16³ × 8, 24³ × 8, and 32³ × 8, where the largest volume varies in linear size between 5.6 fm (at T = 139 MeV) and 4.0 fm (at T = 195 MeV). The chiral condensates, connected and disconnected susceptibilities and the Dirac eigenvalue spectrum are reported and compared between different volumes as well as with the staggered results. We find a pseudo-critical temperature, T_c , of approximately 165 MeV and strong finite volume dependence below T_c. Clear evidence is seen for U(1)_A symmetry breaking above T_c which is quantitatively explained by the measured density of near-zero modes in accordance with the dilute instanton gas approximation.
      The second study targets on a line of constant physics with pions of physical mass, which is the very first study using a chiral lattice fermion formulaation. We continue to use the basic setup from the m_π ≈ 200 MeV simulations, except that we use a generalized form of domain wall fermions, known as the M ̈bius fermions, to further reduce the residual chiral symmetry breaking present in the domain wall formulation with finite extent in the fifth dimension. Preliminary results including the chiral condensates and the susceptibilities are reported for two space-time volumes of 32³ × 8 and 64³ × 8. We observe a dramatic increase in the disconnected susceptibilities and a shift in the pseudo-critical temperature from 165 MeV to about 154 MeV, when the pion mass is decreased from 200 MeV to 135 MeV.

description: We analyze the dynamics of entanglement entropy in a generic quantum many-body open system from the perspective of quantum information and error corrections. We introduce a random unitary circuit model with intermittent projective measurements, in which the degree of information scrambling by the unitary and the rate of projective measurements are independently controlled. This model displays two stable phases, characterized by the volume-law and area-law scaling entanglement entropy in steady states. The transition between the two phases is understood from the point of view of quantum error correction: the chaotic unitary evolution protects quantum information from projective measurements that act as errors. A phase transition occurs when the rate of errors exceeds a threshold that depends on the degree of information scrambling. We confirm these results using numerical simulations and obtain the phase diagram of our model. Our work shows that information scrambling plays a crucial role in understanding the dynamics of entanglement in an open quantum system and relates the entanglement phase transition to changes in quantum channel capacity.

“Do You Think the Angels Will Speak Spanish?”: Nurses’ Experiences of Death in Pediatric Oncology

description: Caring for children dying of cancer and families experiencing immense suffering is challenging complex work. Pediatric oncology nurses attend to the physical and emotional needs of children and their families during the illness progression, at the moment of death, and beyond, however, little is known about how they themselves are affected, and how this influences the care they give. Our intent with this philosophical hermeneutic research was to add to understandings of these effects on pediatric oncology nurses and to support them in this challenging component of their work. This is a part of the doctoral research of the first author which is published online (Morck, 2014), and was supervised by the second author. Fifteen pediatric oncology registered nurses were interviewed to expand our understanding of this topic. These data were then analyzed according to hermeneutic tradition as guided by the philosophical hermeneutics of Hans-Georg Gadamer. Findings from this research revealed nurses struggled to navigate the ideals of nursing versus the realities of practice when working with children who may die. This called for them to maintain a fine balance between the personal and the professional. This ontological struggle is not absolute but premised on a shifting continuum based on a complexity of personal and professional beliefs, experiences, and expectations. There needs to be a reminder that death continues to be an unfortunate constant in the work of these nurses - - a reality, that in many ways, society has turned away from and hidden, a reality that has shaped the way death is experienced within pediatric oncology. This common middle ground is what nurses called for in order to be sustained and remain in their work. Research and transformative education that specifically addresses the tension created by insufficient end of life and death education is required for nurses to feel more comfortable and competent within the ontology of death and dying. This necessitates a re-conceptualization of how death is processed in pediatric oncology.

description: The degree of saturation in tailings above the water table has been a subject of much research in recent times. Such an assessment is important when determining, for instance, the extent of the liquefiable zone in a tailings profile. Full saturation below the water table and within the capillary fringe is well understood. Above the capillary fringe, layers of finer (silty) and coarser (sandy) tailings often exist within the profile. Some of the finer layers remain saturated, in a process of desiccation, with pore water held in suction (negative pressures). These layers have no hydraulic connection with the groundwater profile below. The saturated layers remain saturated until the suctions exceed the air entry limit of the material. A large database spanning several decades of CPTu probing has been used to develop a method for identification of these saturated layers. Induced dynamic pore pressures in saturated layers above the water table dissipate to ambient negative values in classical pore pressure dissipation tests similar to those found below the water table. These results prove saturation of the layers because such pore pressure dissipation behaviour would not be possible in unsaturated material. Additionally, suction probe measurements carried out in these layers to measure the suctions and air entry values has been part of ongoing research to assess the limiting (air entry) properties of the tailings. Using the pore pressure dissipation and suction measurement data, the dynamic pore pressure trace in the tailings layers above the water table has been investigated. In unsaturated materials the dynamic pore pressure response closely follows the zero value; i.e., there is practically no dynamic response in unsaturated tailings. When probing through saturated layers, the dynamic pore pressure response is either positive (in contractive material) or negative (in dilative material). Using the dynamic pore pressure traces in saturated layers, where pore pressure dissipation results have proven saturation, a methodology is proposed to identify saturated and unsaturated layers in the entire profile. This methodology is the subject of this paper.

description: We study semi-inclusive charmless decays $B \to πX$, where $X$ does not contain a charm (anti)quark. The mode $\bar B^0 \to π^- X$ turns out to be be particularly useful for determination of the CKM matrix element $|V_{ub}|$. We present the branching ratio (BR) of $\bar B^0 \to π^- X$ as a function of $|V_{ub}|$, with an estimation of possible uncertainty. The BR is expected to be an order of $10^{-4}$.

An H-Theorem for the Lattice Boltzmann Approach to Hydrodynamics

description: The lattice Boltzmann equation can be viewed as a discretization of the continuous Boltzmann equation. Because of this connection it has long been speculated that lattice Boltzmann algorithms might obey an H-theorem. In this letter we prove that usual nine-velocity models do not obey an H-theorem but models that do obey an H-theorem can be constructed. We consider the general conditions a lattice Boltzmann scheme must satisfy in order to obey an H-theorem and show why on a lattice, unlike the continuous case, dynamics that decrease an H-functional do not necessarily lead to a unique ground state.

description: Neutron production via ^{4}He breakup and p(p, n{pi}^+)p is considered in the innermost region of an accretion disk surrounding a Kerr Black Hole. These reactions occur in a plasma in Wien equilibrium, where (radiatively produced) pair production equals annihilation. Cooling of the disk is assumed to be due to unsaturated inverse Comptonization of external soft photons and to the energy needed to ignite both nuclear reactions. Assuming matter composition of 90% Hydrogen and 10% He, it is shown that, close to the border of this region, neutron production is essentially from ^{4}He breakup. Close to the horizon, the contribution from p(p, n{pi}^+)p to the neutron production is comparable to that from the breakup. It is shown that the viscosity generated by the collisions of the accreting matter with the neutrons may drive stationary accretion, for accretion rates below a critical value. In this case, solution to the disk equations is double-valued and for both solutions protons overnumber the pairs. It is claimed that these solutions may mimic the states of high and low luminosity observed in Cygnus X-1 and related sources. This would be explained either by the coupling of thermal instability to the peculiar behavior of the viscosity parameter alpha with the ion temperature that may intermittently switch accretion off or by the impossibility of a perfect tuning for both thermal and pair equilibrium in the disk, a fact that forces the system to undergo a kind of limit cycle behavior around the upper solution.

description: We provide analytical results for a static portfolio optimization problem with two coherent risk measures. The use of two risk measures is motivated by joint decision-making for portfolio selection where the risk perception of the portfolio manager is of primary concern, hence, it appears in the objective function, and the risk perception of an external authority needs to be taken into account as well, which appears in the form of a risk constraint. The problem covers the risk minimization problem with an expected return constraint and the expected return maximization problem with a risk constraint, as special cases. For the general case of an arbitrary joint distribution for the asset returns, under certain conditions, we characterize the optimal portfolio as the optimal Lagrange multiplier associated to an equality-constrained dual problem. Then, we consider the special case of Gaussian returns for which it is possible to identify all cases where an optimal solution exists and to give an explicit formula for the optimal portfolio whenever it exists.

An Input-Output Parametrization of Stabilizing Controllers: amidst Youla and System Level Synthesis

description: This paper proposes a novel input-output parametrization of the set of internally stabilizing output-feedback controllers for linear time-invariant (LTI) systems. Our underlying idea is to directly treat the closed-loop transfer matrices from disturbances to input and output signals as design parameters and exploit their affine relationships. This input-output perspective is particularly effective when a doubly-coprime factorization is difficult to compute, or an initial stabilizing controller is challenging to find; most previous work requires one of these pre-computation steps. Instead, our approach can bypass such pre-computations, in the sense that a stabilizing controller is computed by directly solving a linear program (LP). Furthermore, we show that the proposed input-output parametrization allows for computing norm-optimal controllers subject to quadratically invariant (QI) constraints using convex programming.
