Stakeholders' Views on the Movement to Reduce Youth Incarceration

Youth incarceration rates have changed dramatically over the past 10 years . Following two decades of "tough-on-crime" policies and steep surges in juvenile incarceration during the 1980s and 1990s, the field is now seeing sharp reductions in youth confinement . The latest data from the US Justice Department showed that the rate of youth in confinement dropped 41% between 2001 and 2011 . Since 2001, 48 states have experienced such a decline . Several states cut their confinement rates by half or more . Juvenile facilities have closed in a dozen states, with more than 50 facilities closing in the past five years alone .The National Council on Crime and Delinquency (NCCD) decided to seek the opinions of system stakeholders regarding these changes . These stakeholders included advocates who successfully pressured their local systems to adopt reforms; the majority of study participants work inside the system as judges, probation chiefs, probation officers, directors of child welfare agencies, elected officials, and district attorneys.Through interviews and listening sessions, these system stakeholders expressed their beliefs that declining youth crime and rising costs were key drivers of the current trend . Additionally, respondents said that many of these successes were driven by successful legislation, innovative incentives built into state budgets, decisions to place youth close to home, and supervision strategies that rely on positive relationships between youth and their families

Santa Ana Phonology

The seven Keresan-speaking Pueblos of north-central New Mexico with their present population of some 8,000 persons have long been in contact with Spanish and Anglo-American Cultures. Despite centuries of contact, the language of these Pueblos, like many other aspects of their culture, today remains comparatively intact and shows little evidence of soon dying out. Linguistically, however, Keresan continues to be little known, both as to its structure and its relationship to other languages

Grammatical Structure of Santa Ana Keresan

It is hoped that the present study will contribute to the knowledge of the grammatical structure of Keresan, which to the present has received little systematic treatment. Published grammatical material is confined to Boas\u27 annotated Laguna texts and Toomey\u27s brief outline. Unpublished manuscripts include Spencer\u27s Master\u27s Thesis which contains considerable data but suffers from faulty transcription, a failure to keep the several dialects separate and a lack of an over-all structural analysis. At the present time a thorough analysis of Acoma Keresan is being undertaken by Wick R. Miller of the University of California

The use of mixture density networks in the emulation of complex epidemiological individual-based models

Complex, highly-computational, individual-based models are abundant in epidemiology. For epidemics such as macro-parasitic diseases, detailed modelling of human behaviour and pathogen life-cycle are required in order to produce accurate results. This can often lead to models that are computationally-expensive to analyse and perform model fitting, and often require many simulation runs in order to build up sufficient statistics. Emulation can provide a more computationally-efficient output of the individual-based model, by approximating it using a statistical model. Previous work has used Gaussian processes (GPs) in order to achieve this, but these can not deal with multi-modal, heavy-tailed, or discrete distributions. Here, we introduce the concept of a mixture density network (MDN) in its application in the emulation of epidemiological models. MDNs incorporate both a mixture model and a neural network to provide a flexible tool for emulating a variety of models and outputs. We develop an MDN emulation methodology and demonstrate its use on a number of simple models incorporating both normal, gamma and beta distribution outputs. We then explore its use on the stochastic SIR model to predict the final size distribution and infection dynamics. MDNs have the potential to faithfully reproduce multiple outputs of an individual-based model and allow for rapid analysis from a range of users. As such, an open-access library of the method has been released alongside this manuscript

Comparative study of cadmium telluride solar cell performance on different TCO‐coated substrates under concentrated light intensities

Concentrating photovoltaics is an attractive route for achieving high power output with thin film solar cells, using low-cost optics. In this work, the performance of CdTe:As thin film solar cells on two different transparent conducting oxide (TCO)-coated substrates is investigated and compared under varying concentrated light intensities (1–6.3 Suns). Samples tested had CdZnS/CdTe:As devices deposited atop of either a soda-lime glass with a fluorine-doped tin oxide TCO or an ultra-thin glass (UTG) with an aluminium zinc oxide TCO and ZnO high-resistive transparent (HRT) layer. Device current density was found to increase linearly with increased light intensities, for both sample configurations. Power conversion efficiencies of both device samples decreased with increased light intensity, due to a decrease in fill factor. The fill factor, for both sample configurations, was affected by reducing shunt resistance with increasing illumination intensity. The two device types performed differently at the high illumination intensities due to their series resistance. Light-soaking devices under 6.3 Suns illumination intensity for 90 min showed no significant performance degradation, indicative of relatively stable devices under the highest illumination intensity tested. Efficiency limiting factors are assessed, evaluated and discussed

Verification of a Distributed Ledger Protocol for Distributed Autonomous Systems Using Monterey Phoenix

Autonomous multi-vehicle systems are becoming increasingly relevant in military operations and have demonstrated potential applicability in civilian environments as well. A problem emerges, however, when logging data within these systems. In particular, potential loss of individual vehicles and inherently lossy and noisy communications environments can result in the loss of important mission data. This paper describes a novel distributed ledger protocol that can be used to ensure that the data in such a system survives and documents verification of the behavioral correctness of this protocol using informal verification methods and tools provided by the Monterey Phoenix project

Motherhood in the teens and twenties: some surprises.

We report a study of the association of health and social support variables with motherhood in teenagers and older mothers. Both teenage and older mothers reported poorer physical and mental health and fewer and less frequent social contacts than their nulliparous peers. Contrary to expectation, however, older mothers reported less extensive and less adequate social support networks than did teenagers

Wireless energy behaviour monitoring (Wi-be) for office buildings

This paper presents a study on reduction of energy consumption in buildings through behaviour change informed by wireless monitoring systems for energy, environmental conditions and people positions. A key part to the Wi-Be system is the ability to accurately attribute energy usage behaviour to individuals, so they can be targeted with specific feedback tailored to their preferences. The use of wireless technologies for indoor positioning was investigated to ascertain the difficulties in deployment and potential benefits. The research to date has demonstrated the effectiveness of highly disaggregated personal-level data for developing insights into people’s energy behaviour and identifying significant energy saving opportunities (up to 77% in specific areas). Behavioural research addressed social issues such as privacy, which could affect the deployment of the system. Radio-frequency research into less intrusive technologies indicates that received-signal-strength-indicator-based systems should be able to detect the presence of a human body, though further work would be needed in both social and engineering areas

Protocol for a mixed-methods investigation of quality improvement in early childhood education and care in Australia

International recognition of the early years as a crucial foundational period has led to the design and implementation of quality rating and improvement systems (QRIS) that define, communicate, and monitor the components of quality in early childhood education and care (ECEC). The aim of these policies is to achieve effective quality assurance and improvement through a system-oriented approach to assessment and evaluation. Informed by ecological systems theory, this paper outlines a three-phase, mixed-methods design for researching a national sample of child care centres that showed overall improvement on the Australian National Quality Standard (NQS) assessment and rating (A&R) criteria. The study samples are drawn from a national dataset of centre-based child care services with two or more A&R rounds and an initial rating of Working Towards NQS (N = 1,935). The results of this study will provide insights into the macro-, exo-, meso- and micro-systems level factors and strategies that support quality in ECEC services
