The New Orleans Criminal Legal System: A Flowing River

Ask anyone from New Orleans and they will tell you the city has not been the same since the storm. Although the city has persevered through many storms and hurricanes in its three-hundred-year history, this particular storm—Hurricane Katrina—is notorious for the transformation it brought to New Orleans in the years that followed. The makeup, culture, and rhythm of New Orleans have changed, but so too have the various systems that give the city its tempo—particularly the criminal legal system. Hurricane Katrina was a disaster that revealed deficiencies, abnormalities, and injustices in the New Orleans criminal legal system. Some responses to these revelations were criticized and some were supported, and what we have today in 2020—fifteen years after the storm—is a city that is not the same. To understand the change in the city’s criminal legal system, we will start by looking at how the Vera Institute of Justice (Vera) came to work in New Orleans, then we will review Vera’s involvement in various efforts to reduce the jail size—in population and in structure. Finally, we will list some lessons learned since Vera began its work in New Orleans

Probing the structure of the cold dark matter halo with ancient mica

Mica can store (for >1 Gy) etchable tracks caused by atoms recoiling from WIMPs. Ancient mica is a directional detector despite the complex motions it makes with respect to the WIMP "wind". We can exploit the properties of directionality and long integration time to probe for structure in the dark matter halo of our galaxy. We compute a sample of possible signals in mica for a plausible model of halo structure.Comment: 7 pages, 2 figure

Electrical capacitance tomography for flow imaging: System model for development of image reconstruction algorithms and design of primary sensors

A software tool that facilitates the development of image reconstruction algorithms, and the design of optimal capacitance sensors for a capacitance-based 12-electrode tomographic flow imaging system are described. The core of this software tool is the finite element (FE) model of the sensor, which is implemented in OCCAM-2 language and run on the Inmos T800 transputers. Using the system model, the in-depth study of the capacitance sensing fields and the generation of flow model data are made possible, which assists, in a systematic approach, the design of an improved image-reconstruction algorithm. This algorithm is implemented on a network of transputers to achieve a real-time performance. It is found that the selection of the geometric parameters of a 12-electrode sensor has significant effects on the sensitivity distributions of the capacitance fields and on the linearity of the capacitance data. As a consequence, the fidelity of the reconstructed images are affected. Optimal sensor designs can, therefore, be provided, by accommodating these effect

The DRIFT Project: Searching for WIMPS with a Directional Detector

A low pressure time projection chamber for the detection of WIMPs is discussed. Discrimination against Compton electron background in such a device should be very good, and directional information about the recoil atoms would be obtainable. If a full 3-D reconstruction of the recoil tracks can be achieved, Monte Carlo studies indicate that a WIMP signal could be identified with high confidence from as few as 30 detected WIMP-nucleus scattering events.Comment: 5 pages, 3 figures.

HEA Flexible Learning Practice Guide

This Guide is designed to help practitioners develop flexible learning processes across a range of domains and levels and to aid subsequent implementation. It starts by providing practitioners with some contested definitions of flexible learning and argues a case for a particular approach; it articulates a set of overarching principles for flexible learning processes; covers the parameters of flexible learning and outlines what falls outside of scope; it considers the implications for staff and institutions when operationalising flexible learning processes and possible impact on students; finally, it provides brief synopses of others' innovative approaches in this domain alongside further resources. The immediate intention is to build confidence in those seeking to use more inclusive, collaborative and flexible pedagogical processes in enhancing student success. A longer-term ambition is to develop an emerging network of practitioners as part of our Flexible Learning Community of Practice who can use this Guide as a conduit for sharing further ideas and to use as a springboard for taking flexible learning to a new level. The Guide should be read in conjunction with the illustrative case studies and with the HEA Framework for Flexible Learning in higher education (2015) against which many of its key principles are aligned

Mainstreaming Mental Health Care in 42 Countries.

Abstract-Global consensus and national policies have emphasized deinstitutionalization, or a shift in providing mental health care from institutional to community settings. Yet, psychiatric hospitals and asylums receive the majority of mental health funding in many countries, at odds with research evidence that suggests that services should be delivered in the community. Our aim is to investigate the norms, actors, and strategies that influence the uptake of deinstitutionalization internationally. Our study is informed by prior literature on management and implementation science. The success and failure of mental health care operations depend on identifying and overcoming challenges related to implementing innovations within national contexts. We surveyed 78 experts spanning 42 countries on their knowledge and experiences in expanding community-based mental health care and/or downsizing institution-based care. We also asked them about the contexts in which said methods were implemented in a country. We found that mental health care, whether it is provided in institutions or in the community, does not seem to be standardized across countries. Our analysis also showed that moving deinstitutionalization forward requires meaningful engagement of three types of actors: government officials, health care professionals, and local experts. Progress toward deinstitutionalization depends on the partnerships formed among these actors and with diverse stakeholders, which have the potential to garner resources and to scale-up pilot projects. In conclusion, different countries have adapted deinstitutionalization in ways to meet idiosyncratic situations and population needs. More attention should be given to the management and implementation strategies that are used to augment treatment and preventive services

X-ray observations of the galaxy cluster Abell 2029 to the virial radius

We present Suzaku observations of the galaxy cluster Abell 2029, which exploit Suzaku's low particle background to probe the ICM to radii beyond those possible with previous observations (reaching out to the virial radius), and with better azimuthal coverage. We find significant anisotropies in the temperature and entropy profiles, with a region of lower temperature and entropy occurring to the south east, possibly the result of accretion activity in this direction. Away from this cold feature, the thermodynamic properties are consistent with an entropy profile which rises, but less steeply than the predictions of purely gravitational hierarchical structure formation. Excess emission in the northern direction can be explained due to the overlap of the emission from the outskirts of Abell 2029 and nearby Abell 2033 (which is at slightly higher redshift). These observations suggest that the assumptions of spherical symmetry and hydrostatic equilibrium break down in the outskirts of galaxy clusters, which poses challenges for modelling cluster masses at large radii and presents opportunities for studying the formation and accretion history of clusters.Comment: 15 pages, 14 figures.

Track Reconstruction and Performance of DRIFT Directional Dark Matter Detectors using Alpha Particles

First results are presented from an analysis of data from the DRIFT-IIa and DRIFT-IIb directional dark matter detectors at Boulby Mine in which alpha particle tracks were reconstructed and used to characterise detector performance--an important step towards optimising directional technology. The drift velocity in DRIFT-IIa was [59.3 +/- 0.2 (stat) +/- 7.5 (sys)] m/s based on an analysis of naturally-occurring alpha-emitting background. The drift velocity in DRIFT-IIb was [57 +/- 1 (stat) +/- 3 (sys)] m/s determined by the analysis of alpha particle tracks from a Po-210 source. 3D range reconstruction and energy spectra were used to identify alpha particles from the decay of Rn-222, Po-218, Rn-220 and Po-216. This study found that (22 +/- 2)% of Po-218 progeny (from Rn-222 decay) are produced with no net charge in 40 Torr CS2. For Po-216 progeny (from Rn-220 decay) the uncharged fraction is (100 +0 -35)%.Comment: 27 pages, 12 figures, 5 tables. Submitted to Nuclear Instruments and Methods in Physics Research, Section A.

Ethnic Differences in Children’s Entry into Public Mental Health Care via Emergency Mental Health Services

For children and youth making a mental health crisis visit, we investigated ethnic disparities in whether the children and youth were currently in treatment or whether this crisis visit was an entry or reentry point into mental health treatment. We gathered Medicaid claims for mental health services provided to 20,110 public-sector clients ages 17 and younger and divided them into foster care and non-foster care subsamples. We then employed logistic regression to analyze our data with sociodemographic and clinical controls. Among children and youth who were not placed in foster care, African Americans, Latinos, and Asian Americans were significantly less likely than Caucasians to have received mental health care during the three months preceding a crisis visit. Disparities among children and youth in foster care were not statistically significant. Ethnic minority children and youth were more likely than Caucasians to use emergency care as an entry or reentry point into the mental health treatment, thereby exhibiting a crisis-oriented pattern of care
