Bail Reform in Cook County: Using Novel Data to Evaluate General Order 18.8A
Creators: name: Pfeiffer, Hanna
Publisher: name: University of Chicago
Year: 2019
Subjects: subject: Cook County Jail
subject: General Order 18.8A
subject: bail reform

description: Topic: This paper evaluates General Order 18.8A, a bail reform policy in Cook County, Illinois. Methods: I use novel data obtained via Freedom of Information Act Request from the Cook County Sheriff’s Office concerning people incarcerated in Cook County Jail. I support my analysis of this data with other data sources. Further, I conduct expert interviews for a mixed-methods approach. Results: The analysis concludes that General Order 18.8A has some positive effects, including the increased use of non-monetary bail and a decrease in the Cook County Jail’s population, especially the population detained on misdemeanor offenses, but that General Order 18.8A did not meet its goals. Discussion: The paper finds that although General Order 18.8A has changed the types of bonds judges are assigning and has decreased the jail population, it has not truly reformed bail in Cook County.

description: Two qubit quantum computations are viewed as two player, strictly competitive games and a game-theoretic measure of optimality of these computations is developed. To this end, the geometry of Hilbert space of quantum computations is used to establish the equivalence of game-theoretic solution concepts of Nash equilibrium and mini-max outcomes in games of this type, and quantum mechanisms are designed for realizing these mini-max outcomes.

description: A strong-coupling series expansion for the Green's function and the extremely-correlated Fermi liquid (ECFL) theory are used to calculate the moments of the electronic spectral functions of the infinite-U Hubbard model. Results from these two complementary methods agree very well at both, low densities, where the ECFL solution is the most accurate, and at high to intermediate temperatures, where the series converge. We find that a modified first moment, which underestimates the contributions from the occupied states and is accessible in the series through the time-dependent Green's function, best describes the quasiparticle peak location in the strongly-correlated regime. This is examined by the ECFL results at low temperatures, where it is shown that the spectral function is largely skewed towards the occupied states.

Publisher: name: Roper Center for Public Opinion Research
Year: 2023

description: Time-sharing Experiments for the Social Sciences (TESS) offers researchers the opportunity to capture the internal validity of experiments. Investigators submit proposals, and TESS fields successful proposals for free on a representative sample of adults in the United States. This experiment was conducted to explore impacts of affectionate touch on relational-cognitive changes and relationship and psychological wellbeing in couples. Respondents answered measures of marital quality/distress before being randomly assigned to visualize one of four scenarios: affectionate touch received from their spouse during a conflict discussion; no affectionate touch received during a conflict discussion; affectionate touch received from their spouse during a non-conflict discussion; or no affectionate touch received during a non-conflict discussion. A total of 1,140 married respondents participated. Respondents indicated their emotional response to the hypothetical interaction, sense of relationship satisfaction brought on by the interaction, current feelings of loneliness and isolation, and intent to pursue emotional intimacy with their spouse. This allowed for comparison of pre- and post-treatment relationship quality across treatments.

description: Purpose This randomized controlled trial compared the experimental Rapid Syllable Transition (ReST) treatment to the Nuffield Dyspraxia Programme–Third Edition (NDP3; Williams & Stephens, 2004), used widely in clinical practice in Australia and the United Kingdom. Both programs aim to improve speech motor planning/programming for children with apraxia of speech (CAS), but they differ in types of stimuli used, level of stimulus complexity at initiation of treatment, and the principles of motor learning that they apply.
Method Treatment was delivered to 26 children with mild to severe CAS aged 4–12 years through trained and supervised speech-language pathology students in 1-hr sessions, 4 days a week for 3 weeks at a university clinic. Articulation and prosodic accuracy were assessed at pretreatment, 1 week, 1 month, and 4 months posttreatment using blinded independent assessors to compare treatment, maintenance, and generalization effects.
Results The ReST and NDP3 treatments demonstrated large treatment effects. ReST maintained treatment gains from 1-week to 4-months posttreatment more effectively than the NDP3. Significant generalization to untreated stimuli was observed for both ReST and NDP3. Conclusions ReST and NDP3 have strong evidence of treatment and generalization gains in children with CAS when delivered intensively. Overall, ReST has greater external evidence from multiple sources but both treatments have support for clinical use.

description: The holographic isotropization of a highly anisotropic, homogeneous, strongly coupled, non-Abelian plasma was simplified in arXiv:1202.0981 by linearizing Einstein's equations around the final, equilibrium state. This approximation reproduces the expectation value of the boundary stress tensor with a 20% accuracy. Here we elaborate on these results and extend them to observables that are directly sensitive to the bulk interior, focusing for simplicity on the entropy production on the event horizon. We also consider next-to-leading-order corrections and show that the leading terms alone provide a better description of the isotropization process for the states that are furthest from equilibrium.

description: We utilize the Millennium-II simulation databases to study the spin bias of dark subhalos in the Local Group-like systems which have two prominent satellites with comparable masses. Selecting the group-size halos with total mass similar to that of the Local Group (LG) from the friends-of-friends halo catalog and locating their subhalos from the substructure catalog, we determine the most massive (main) and second to the most massive (submain) ones among the subhalos hosted by each selected halo. When the dimensionless spin parameter (lambda) of each subhalo is derived from its specific angular momentum and circular velocity at virial radius, a signal of correlation is detected between the spin parameters of the subhalos and the main-to-submain mass ratios of their host halos at z=0: The higher main-to-submain mass ratio a host halo has, the higher mean spin parameter its subhalos have. It is also found that the correlations exist even for the subhalo progenitors at z=0.5 and z=1. Our interpretation of this result is that the subhalo spin bias is not a transient effect but an intrinsic property of a LG-like system with higher main-to- submain mass ratio, caused by stronger anisotropic stress in the region. A cosmological implication of our result is also discussed.

description: We examine the feasibility of gauge invariant descriptions of the gluon polarization following the proposal that a gauge field can be decomposed into its physical part and its pure gauge part. We show that gauge invariant angular momentum currents can be constructed from summations of gauge variant Noether currents. We present novel expressions of the pure gauge field, which are used to formulate gauge invariant descriptions of the gluon spin and the photon spin. We show that the gauge invariant extension of the Chern-Simons current can describe the spins of the Laguerre-Gauss laser modes. We also discuss the relation of gauge invariant operators and the parton distributions constructed from Dirac variables.

description: We introduce a family of criteria to detect quantum non-Gaussian states of a harmonic oscillator, that is, quantum states that can not be expressed as a convex mixture of Gaussian states. In particular we prove that, for convex mixtures of Gaussian states, the value of the Wigner function at the origin of phase space is bounded from below by a non-zero positive quantity, which is a function only of the average number of excitations (photons) of the state. As a consequence, if this bound is violated then the quantum state must be quantum non-Gaussian. We show that this criterion can be further generalized by considering additional Gaussian operations on the state under examination. We then apply these criteria to various non-Gaussian states evolving in a noisy Gaussian channel, proving that the bounds are violated for high values of losses, and thus also for states characterized by a positive Wigner function.

description: We present results of the first experiment to probe for the electric dipole moment (EDM) of the electron using an $Ω$-doublet state in a polar molecule. If the molecule is both massive and has a large molecular-fixed frame dipole moment, then the $Ω$-doublet states have the potential to greatly increase the sensitivity of experiments searching for the EDM while also allowing for new methods of systematic error rejection. Here, we use the metastable $a(1)^3Σ^+$ state of lead monoxide (PbO) to probe for the electron EDM. Our best fit for the electron EDM of $d_e = (-4.4\pm9.5_\text{stat}\pm1.8_\text{syst})\times10^{-27}\ecm$ allows us to place an upper limit on the magnitude of the EDM of $|d_e|<1.7\times10^{-26}\ecm$ (90% confidence). While this is less stringent than limits from other, previous experiments, our work emphasizes the systematic error rejection properties associated with the $Ω$-doublet level structure. The results should inform the work of other, ongoing experiments that use molecules with analogous level structure.

description: Purpose The current meta-analysis examines recent empirical research studies that have investigated relations among dialect use and the development and achievement of reading, spelling, and writing skills.
Method Studies published between 1998 and 2014 were selected if they: (a) included participants who were in Grades K–6 and were typically developing native English speakers, (b) examined a concurrent quantitative relationship between dialect use and literacy, including reading, spelling, or writing measures, and (c) contained sufficient information to calculate effect size estimates. Results Upon the removal of one study that was found to be an outlier, the full sample included 19 studies consisting of 1,947 participants, of which the majority (70%) were African American. The results showed a negative and moderate relationship between dialect use and overall literacy performance (M effect size = −0.33) and for dialect and reading (M effect size = −0.32). For spelling and writing, the relationship was negative and small (M effect size = −0.22). Moderator analyses revealed that socioeconomic status and grade level were not significant predictors for relations among dialect use and literacy skills.
Conclusions Implications for practice and future research, including analyzing dialect use in a variety of contexts and examining these relations to literacy outcomes, are discussed.

description: Detailed characterisation of small exoplanets is currently hindered by radial velocity signals arising from the star's intrinsic variability. In extracting the precise radial velocities, we can also extract spectral line profile information. These are useful indicators for the stellar variability processes. However, for them to be optimally used in a global model, it is essential to bear in mind that these indicators are not directly correlated with the radial velocities, but rather shifted by several days. In this talk I will give an overview of this effect as studied on Solar data from the HARPS-N spectrograph, which has been continuously gathering data for over six years.

description: The Coronal Multichannel Polarimeter (CoMP) measures not only the polarization of coronal emission, but also the full radiance profiles of coronal emission lines. For the first time, CoMP observations provide high-cadence image sequences of the coronal line intensity, Doppler shift and line width simultaneously in a large field of view. By studying the Doppler shift and line width we may explore more of the physical processes of CME initiation and propagation. Here we identify a list of CMEs observed by CoMP and present the first results of these observations. Our preliminary analysis shows that CMEs are usually associated with greatly increased Doppler shift and enhanced line width. These new observations provide not only valuable information to constrain CME models and probe various processes during the initial propagation of CMEs in the low corona, but also offer a possible cost-effective and low-risk means of space weather monitoring.

description: This study examines Slovak dialect perceptions from 311 participants in 9 municipalities in Slovakia. Data were collected between 2016 and 2017, utilizing a map task, degree of difference ratings, and other Likert scale tasks to assess participants’ perceptions of and attitudes about dialects in Slovakia.

Participants received blank maps of Slovakia on which to elicit participants’ perceptions of where isoglosses (dialect boundaries) lie. They drew their own isoglosses and were asked to label each dialect region contained within them. Content Analysis was used to code each label for semantic field in order to create composite maps for each label. After analyzing data from each municipality separately, 22 salient categories emerged. To be determined salient in this study, a category had to be marked by at least ten percent of participants per municipality.

The most salient boundaries that emerged from this study were those between central (“correct”) Slovak and “other,” “not central” Slovak; those between “The East” and the rest of Slovakia, and those between “The South” (or, more accurately, “The Hungarian South”) and the rest of Slovakia. This thesis explores those ideologies in detail, and takes Nitra as a case study for the discussion.

description: We introduce and characterize two different measures which quantify the level of synchronization of interacting continuous variable quantum systems. The two measures allow to extend to the quantum domain the notions of complete and phase synchronization. The Heisenberg principle sets a universal bound to complete synchronization. The measure of phase synchronization is in principle unbounded, however in the absence of quantum resources (e.g. squeezing) the synchronization level is bounded below a certain threshold. We elucidate some interesting connections between entanglement and synchronization and, finally, discuss an application based on quantum opto-mechanical systems.

description: Focusing on the particular case of the discrete symmetry group Z_N x Z_N, we establish a mapping between symmetry protected topological phases and symmetry broken phases for one-dimensional spin systems. It is realized in terms of a non-local unitary transformation which preserves the locality of the Hamiltonian. We derive the image of the mapping for various phases involved, including those with a mixture of symmetry breaking and topological protection. Our analysis also applies to topological phases in spin systems with arbitrary continuous symmetries of unitary, orthogonal and symplectic type. This is achieved by identifying suitable subgroups Z_N x Z_N in all these groups, together with a bijection between the individual classes of projective representations.

description: The next generation of nuclear reactor designs promise to provide clean, safe, and efficient energy to address our current climate crisis. But with these new technologies, nuclear fuel materials must be carefully designed and understood to meet these demands. Candidate oxide and metallic nuclear fuel materials being considered for use in these new reactor technologies, despite their potential, still have significant remaining materials challenges in understanding their long-term performance and integrity under extreme reactor conditions. As such these candidate fuels require extensive materials characterization to understand their long-term performance under reactor conditions. The objective of this study is to evaluate the microstructural evolution of candidate fuels U-50wt%Zr and ThO2 under the following contexts: 1) Investigation of phase stability in candidate metallic fuel U-50wt%Zr under thermal and irradiation treatment; 2) Investigate localized thermal properties of candidate oxide fuel ThO2 under irradiation through a novel correlative microscopy approach. The influence of thermal and irradiation treatment on phase stability in δ-U50wt%Zr was investigated through conventional APT-TEM methodology. U-Zr is a candidate metallic fuel for advanced fast reactor applications. However, there is still work remaining to better understand how these materials evolve under extreme reactor conditions, especially for the δU-50wt%Zr composition. Metallic fuels are susceptible to significant chemical redistribution under extreme conditions resulting in potential degradation of fuel properties and performance. In these experiments, U-50wt%Zr was subjected to thermal annealing and proton irradiation respectively. These treatments produced very different modulated structures in U-50wt%Zr, and the implications of such on phase stability in U-50wt%Zr will be discussed. Additionally, long-term nuclear reactor operation hinges upon efficient thermal transport in nuclear fuels. There is a critical need to understand localized thermal transport in these materials to enable intelligent design of high-performance fuels. A novel correlative atom probe tomography (APT)-transmission electron microscopy (TEM) approach was developed to investigate the influence of irradiation defects on localized thermal diffusivity in ThO2 upon proton irradiation, and implications of such results will be discussed.

description: We employ quantum Monte Carlo techniques to calculate the $Z_2$ topological invariant in a two-dimensional model of interacting electrons that exhibits a quantum spin Hall topological insulator phase. In particular, we consider the parity invariant for inversion-symmetric systems, which can be obtained from the bulk's imaginary-time Green's function after an appropriate continuation to zero frequency. This topological invariant is used here in order to study the trivial-band to topological-insulator transitions in an interacting system with spin-orbit coupling and an explicit bond dimerization. We discuss the accessibility and behavior of this topological invariant within quantum Monte Carlo simulations.

description: We investigate the behavior of the recently proposed quantum Google algorithm, or quantum PageRank, in large complex networks. Applying the quantum algorithm to a part of the real World Wide Web, we find that the algorithm is able to univocally reveal the underlying scale-free topology of the network and to clearly identify and order the most relevant nodes (hubs) of the graph according to their importance in the network structure. Moreover, our results show that the quantum PageRank algorithm generically leads to changes in the hierarchy of nodes. In addition, as compared to its classical counterpart, the quantum algorithm is capable to clearly highlight the structure of secondary hubs of the network, and to partially resolve the degeneracy in importance of the low lying part of the list of rankings, which represents a typical shortcoming of the classical PageRank algorithm. Complementary to this study, our analysis shows that the algorithm is able to clearly distinguish scale-free networks from other widespread and important classes of complex networks, such as Erdős-Rényi networks and hierarchical graphs. We show that the ranking capabilities of the quantum PageRank algorithm are related to an increased stability with respect to a variation of the damping parameter $α$ that appears in the Google algorithm, and to a more clearly pronounced power-law behavior in the distribution of importance among the nodes, as compared to the classical algorithm. Finally, we study to which extent the increased sensitivity of the quantum algorithm persists under coordinated attacks of the most important nodes in scale-free and Erdős-Rényi random graphs.

description: Columbia University alumni enjoy access to a wide array of electronic resources -- materials from dozens of providers, hundreds of databases, and hundreds of thousands of e-book and e-journal titles. Yet, alumni regularly express frustration with the lack of content available to them and indicate that there is not enough material in their discipline(s). This negatively impacts alumni relationships with the library and university, affecting current and potential donor relations. After reviewing alumni feedback from e-resource problem reports and donor solicitations, it became apparent to electronic resources librarians that the presentation and discovery of alumni e-resources was responsible for negatively impacting the user experience. E-resource librarians recognized that particular functionality was lacking for alumni, which they would have had as students. This includes an e-journal portal, openURL linking, and Web-scale discovery. Through invoking best practices in both e-resources management and fundraising management and applying these principles to alumni e-resources services, the alumni experience can be positively transformed. The improved alumni research experience demonstrates continued library value. It fosters the ongoing reciprocal relationship between library and alumni, respecting alumni’s role as lifelong learners and library supporters.. This poster outlines our proposal to transform Columbia University Libraries’ static alumni portal into a modern and dynamic tool for alumni research and engagement. It contains visuals of the existing alumni page alongside the proposed enhanced pages, highlighting new functionality and features.

description: Cyclotron resonance scattering features observed in the spectra of some X-ray pulsars show significant changes of the line energy with the pulsar luminosity. At high luminosities, these variations are often associated with the onset and growth of the accretion column, which is believed to be the origin of the observed emission and of the cyclotron lines. However, this scenario inevitably implies large gradient of the magnetic field strength within the line-forming region, which makes the formation of the observed line-like features problematic. Moreover, the observed variation of the cyclotron line energy is much smaller than could be anticipated for the corresponding luminosity changes. We argue here that a more physically realistic situation is that the cyclotron line forms when the radiation emitted by the accretion column is reflected from the neutron star surface, where the gradient of the magnetic field strength is significantly smaller. We develop here the reflection model and apply it to explain the observed variations of the cyclotron line energy in a bright X-ray pulsar V 0332+53 over a wide range of luminosities.

description: We present a method of constructing a space of quantum states for a field theory: given phase space of a theory, we define a family of physical systems each possessing a finite number of degrees of freedom, next we define a space of quantum states for each finite system, finally using projective techniques we organize all these spaces into a space of quantum states which corresponds to the original phase space. This construction is kinematic in this sense that it bases merely on the structure of the phase space and does not take into account possible constraints on the space. The construction is a generalization of a construction by Kijowski - the latter one is limited to theories of linear phase spaces, while the former one is free of this limitation.

description: In 2016-2018 on the base of "North Caucasus FSAC" conducted a study of sterile maternal lines of sorghum and new varieties of Sudanese grass - fertilizer reducing agents, as well as sorghum-Sudanese hybrids obtained on their base, which clarified the economic and biological characteristics and their inheritance in hybrids in comparison with the average parent form indicators. The combination of Zersta 90C x Sputnitsa (Gvardeyets) did not lengthen the sprouting-sprouting season during the growing season compared with the average duration of the parental forms, and during the full ripeness period the grain decreased by 2 days. In variants involving the lines Knyazhna and Zersta 38A, similar indicators increased. Plant height in hybrids is inherited with a high degree of heterosis. The most intensive initial growth of plants on the 30th day of the growing season was found in the variant Zersta 90C x Sputnitsa (71 cm). The heterosis of this trait was 17.5 cm. In the phase of seed ripening, the heterosis indices of this trait compared to the parental forms were 98.5 cm in the hybrid with the Zersta 38A line and 50.5 cm with the Zersta 90C. The true heterosis of increasing the length and width of the leaf in the Zersta 90C x Sputnitsa variant was 11.0 cm and 0.6 cm, respectively. On average, the green leaf mass of the three mowings was obtained from Zersta 38A x Sputnitsa (37.8%) Zersta 90C x Sputnitsa (36.5%), which is 5.1% and 3.8% more than the Navigator standard. The highest yields of green mass and hay were obtained from the Zersta 90C x Sputnitsa variants (61.1 t / ha and 13.2 t / ha), as well as from A-63 x Sputnitsa (58.9 t / ha and 12.7 t / ha). The magnitude of the true heterosis of the yield of green mass obtained from the hybrids and the average data of their parental forms is 21.8 t / ha (55.4%) in Zersta 90C x Sputnitsa, 22.9 t / ha (66.5%) in Zersta 38A x Sputnitsa and 20.8 t / ha (54.6%) in A.63 x Sputnitsa. In the first crop, Gvardeyets hybrid produced 23.4 t / ha of green mass, 28.6 t / ha in the second, and 9.1 t / ha in the third. The protein content in the absolutely dry mass was 10.17%, fiber 29.98%.

Psyllaephagus

description: Psyllaephagus Ashmead
 Psyllaephagus Ashmead, 1900: 382. Type-species: Encyrtus pachypsyllae Howard, by original designation.
 Diagnosis. Body generally bright metallic green to dark greenish blue; legs generally pale, except some coxae and sometimes some areas of femora and tibiae darker; wings hyaline; forewing marginal vein punctiform; mandibles with one or two teeth and a broad truncation; hypopygium not extending more than two-thirds length of metasoma. Primary parasitoids of psyllids.
 Remarks. Generic synonymy was dealt with in detail by (Noyes & Hayat 1984; Hayat 2006). The genus is classified in Encyrtinae, tribe Trechnitini Hoffer and subtribe Metaprionomitina Hoffer.
 India is bestowed with a rich Psyllaephagus diversity in various climatic zones, but it is very scantly investigated and thorough survey work in the rich areas of the Northeast and the Western Ghats may result in many new species. Presently only the following ten species, excluding the two newly described here, are known — Psyllaephagus africanus Prinsloo, P. a i z a w l e n s i s Singh, P. aligarhensis Shafee, Alam & Agarwal, P. bengalensis Hayat, P. macrohomotomae Singh & Agarwal, P. mesohomotomae Singh & Agarwal, P. mycopsyllus Singh, P. phylloplectrae Sushil & Khan, P. solanensis Sushil & Khan, and P. tekeddyensis Singh & Agarwal. Some important references on the genus from India are those of Shafee et al. (1975), Singh & Agarwal (1993), Sushil & Khan (1995), Singh (1996) and Hayat (2003 & 2006).
 Singh (1996) arranged the Indian species of Psyllaephagus in two informal groups. Species in “Group A” are characterized by a large body size (female length 1.5–3.9 mm, male length 1.3–2.8 mm); female metasoma longer than mesosoma with last tergite long and V-shaped, hence metasoma appearing pointed; outer plate of ovipositor without notch; male antenna with shape of scape and flattened flagellum variable, but setae on flagellum short, less than half width of respective funicle segment. Species in “Group B” are generally smaller (female length 1.2–2.5 mm, male length 0.8–1.8 mm); female metasoma at most equal in length to mesosoma and with last tergite crescent shaped, hence apex of metasoma appearing blunt and rounded; outer plate of ovipositor with a deep notch at the outer distal margin; male with antennal scape normal and funicle segments cylindrical with long wavy setae longer than width of respective funicle segment (Singh 1996).

description: Recent measurements of Efimov resonances in a number of ultracold atom species have revealed an unexpected universality, in which three-body scattering properties are determined by the van der Waals length of the two-body interaction potential. To investigate whether this universality extends to heteronuclear mixtures, we measure loss rate coefficients in an ultracold trapped gas of $^{40}$K and $^{87}$Rb atoms. We find an Efimov-like resonance in the rate of inelastic collisions between $^{40}$K$^{87}$Rb Feshbach molecules and $^{87}$Rb atoms. However, we do not observe any Efimov-related resonances in the rates of inelastic collisions between three atoms. These observations are compared to previous measurements by the LENS group of Efimov resonances in a $^{41}$K and $^{87}$Rb mixture as well as to recent predictions.

description: In a recent Letter [Phys. Rev. Lett. 109, 110502 (2012), arXiv:1204.6528], Bandyopadhyay, Paterek and Kaszlikowski report their analysis of spin coherence time in the radical pair involved in avian magnetoreception, concluding that is of the order of a microsecond. However, a combination of an erroneous numerical calculation together with an incorrect parameter drawn from an experimental source have resulted in the authors underestimating by two orders of magnitude. Consequently, one must reverse the authors' conclusion that the timescale is consistent with experiments on cryptochrome.
Effects of Penetrative Convection on Solar Dynamo

description: Spherical solar dynamo simulations are performed. Self-consistent, fully compressible magnetohydrodynamic system with a stably stratified layer below the convective envelope is numerically solved with a newly developed simulation code based on the Yin-Yang grid. The effects of penetrative convection are studied by comparing two models with and without the stable layer. The differential rotation profile in both models is reasonably solar-like with equatorial acceleration. When considering the penetrative convection, a tachocline-like shear layer is developed and maintained beneath the convection zone without assuming any forcing. While turbulent magnetic field becomes predominant in the region where the convective motion is vigorous, mean-field component is preferentially organized in the region where the convective motion is less vigorous. Especially in the stable layer, the strong large-scale field with a dipole symmetry is spontaneously built up. The polarity reversal of the mean-field component takes place globally and synchronously throughout the system regardless the presence of the stable layer. Our results suggest that the stably stratified layer is a key component for organizing the large-scale strong magnetic field, but is not essential for the polarity reversal.
