National Prisoner Statistics (NPS) on inmates under the jurisdiction of both federal and state correctional authorities.
Investigator(s): Bureau of Justice Statistics This series of studies contains a descriptive analysis of federal and state-operated adult confinement and correctional facilities nationwide. The census included prisons, penitentiaries, and correctional facilities; boot camps; community corrections; prison farms; reception, diagnostic, and classification centers; road camps; forestry and conservation camps; youthful offender facilities (except in California); vocational training facilities; prison hospitals; and correctional drug and alcohol treatment facilities. Variables include physical security, age of facilities, functions of facilities, programs, inmate work assignments, staff employment, facilities under court order/consent decree for conditions of confinement, capital and operating expenditures, custody level of residents/inmates, one-day and average daily population counts, race/ethnicity of inmates, inmate deaths, special inmate counts, and assaults and incidents by inmates. The institution is the unit of analysis. The Census of State and Federal Adult Correctional Facilities is produced every 5 years.
The data contain records of sentenced offenders released from the custody of the Bureau of Prisons (BOP) during fiscal year 2015. The data include commitments of United States District Court, violators of conditions of release (e.g., parole, probation, or supervised release violators), offenders convicted in other courts (e.g., military or District of Columbia courts), and persons admitted to prison as material witnesses or for purposes of treatment, examination, or transfer to another authority. Records of offenders who exit federal prison temporarily, such as for transit to another location, to serve a weekend sentence, or for health care, are not included in the exiting cohort. These data include variables that describe the offender, such as age, race, citizenship, as well as variables that describe the sentences and expected prison terms. The data file contains original variables from the Bureau of Prisons' SENTRY database as well as additional analysis variables. Variables containing identifying information (e.g., name, Social Security Number) were either removed, coarsened, or blanked in order to protect the identities of individuals. These data are part of a series designed by the Urban Institute (Washington, D.C.) and the Bureau of Justice Statistics. Data and documentation were prepared by the Urban Institute through 2012. Data from 2013 and on were prepared by Abt Associates.

dataset and Octave/MatLab codes/scripts for data analysis Background: Methods for p-value correction are criticized for either increasing Type II error or improperly reducing Type I error. This problem is worse when dealing with thousands or even hundreds of paired comparisons between waves or images which are performed point-to-point. This text considers patterns in probability vectors resulting from multiple point-to-point comparisons between two event-related potentials (ERP) waves (mass univariate analysis) to correct p-values, where clusters of signiticant p-values may indicate true H0 rejection. New method: We used ERP data from normal subjects and other ones with attention deficit hyperactivity disorder (ADHD) under a cued forced two-choice test to study attention. The decimal logarithm of the p-vector (p') was convolved with a Gaussian window whose length was set as the shortest lag above which autocorrelation of each ERP wave may be assumed to have vanished. To verify the reliability of the present correction method, we realized Monte-Carlo simulations (MC) to (1) evaluate confidence intervals of rejected and non-rejected areas of our data, (2) to evaluate differences between corrected and uncorrected p-vectors or simulated ones in terms of distribution of significant p-values, and (3) to empirically verify rate of type-I error (comparing 10,000 pairs of mixed samples whit control and ADHD subjects). Results: the present method reduced the range of p'-values that did not show covariance with neighbors (type I and also type-II errors). The differences between simulation or raw p-vector and corrected p-vectors were, respectively, minimal and maximal for window length set by autocorrelation in p-vector convolution. Comparison with existing methods: Our method was less conservative while FDR methods rejected basically all significant p-values for Pz and O2 channels. The MC simulations, gold-standard method for error correction, presented 2.78±4.83% of difference (all 20 channels) from p-vector after correction, while difference between raw and corrected p-vector was 5,96±5.00% (p = 0.0003). Conclusion: As a cluster-based correction, the present new method seems to be biological and statistically suitable to correct p-values in mass univariate analysis of ERP waves, which adopts adaptive parameters to set correction.
The National Corrections Reporting Program gathers data on prisoners entering and leaving the custody or supervision of state and federal authorities. The dataset is comprised of four types of data: prisoners who were admitted to prison (Part 1), released from prison (Part 2), released from parole (Part 3), or in prison at year end (Part 4). The National Prison Statistics (NPS) program was established in 1926 by the Bureau of the Census in response to a congressional mandate to compile national information on the populations confined in correctional institutions. This program described the characteristics and counts of prison inmates during each calendar year. Since its initiation, responsibility for this program has shifted among several agencies -- in 1950 it was transferred to the Federal Bureau of Prisons and to the Law Enforcement Assistance Administration in 1971. Since 1972, the Bureau of Census, under agreement with the Department of Justice, has had responsibility for compiling the statistical data. Census staff negotiates directly with each state, assembles and edits the data, and prepares the data for analysis and publication.
Latest figures for the quarter April to June 2021 are provided and compared to the same period in 2020. This is with the exception of the prison population where more recent data are available (30 September 2021).
It covers flows into these services (receptions into prison or probation starts) and flows out (releases from prison or probation terminations) as well as the caseload of these services at specific points in time.

Two reports are being published this quarter: Prisoners Education Trust (4th analysis) and Resolve accredited programme.
Note: Following the publication of the original impact evaluation for the Resolve accredited programme detailed below, a supplementary appendix including additional analysis and descriptive statistics was published in Justice Data Lab statistics: October 2021.
Prisoners’ Education Trust (PET) funds prisoners to study courses via distance learning in subjects and at levels that are not generally available through mainstream education.
This analysis looked at the employment outcomes and reoffending behaviour of 9,041 adults who received grants for distance learning through Prisoners’ Education Trust (PET) schemes between 2001 and 2017. This analysis is a follow up of previous PET analyses which looked at the reoffending behaviour and employment outcomes of a smaller group of people.
The overall results show that those who received PET grants were less likely to reoffend in the year after their release from prison and more likely to be employed, compared with a group of similar offenders who did not receive these grants.
Resolve is a moderate intensity accredited programme designed and delivered by HMPPS. The prison-based programme is a cognitive-behavioural therapy-informed offending behaviour programme, which aims to improve outcomes related to violence in adult males who are of a medium risk of reoffending.
The analysis looked at the reoffending behaviour of 2,509 adult males who participated in the Resolve custody programme at some point between 2011 and 2018 and who were released from prison between 2011 and 2018. It covers one and two-year general and violent reoffending measures.
The headline results for one-year proven general reoffending (includes all reoffending) show that those who took part in the programme in England and Wales were less likely to reoffend, reoffended less frequently and took longer to reoffend than those how did not take part. The headline results for two-year proven general reoffending show that those who took part were less likely to reoffend, reoffended less frequently and took longer to reoffend that those how did not take part. These results were statistically significant.
For proven violent reoffences (a subset of general reoffending), the headline one and two-year results did not show that the programme had a statistically significant effect on a person’s reoffending behaviour, but this should not be taken to mean it fails to have an effect.
Further analyses were also conducted to examine the specific effects of Resolve on relevant sub-groups for proven general reoffending and violent reoffending. Among the one-year violent sub-analyses, those who only participated in Resolve were significantly less likely to reoffend violently and reoffended violently less frequently than those who did not take part. There were no statistically significant sub-analyses for the two-year violent measures.
Organisation can submit information on the individuals they were working with between 2002 and the end of March 2018.

The psychological and physiological health of undergraduates was correlated with the sleep quality, which can be improved through increasing physical activity. However, the correlations between physical activity and sleep quality are subject to various factors. In this study, we investigated the effects of self-control and mobile phone addiction on the correlations between physical activity on undergraduates’ sleep quality at the psychological and behavioral levels. Data was collected through a survey with a convenient sample of 2,274 students in China. The study utilized scales of physical activity, sleep quality, self-control, and mobile phone addiction to quantitatively evaluate the impact of physical activity on the sleep quality of undergraduates. The correlations were analyzed using SPSS 26.0, including descriptive statistics, confidence tests, common method bias tests, correlation analysis, and hypothesis tests. Pearson correlation analysis shows that physical activity was significantly correlated with sleep quality (r = -0.541, p < 0.001), and that physical activity and sleep quality were significantly correlated with self-control and mobile phone addiction. Regression analysis shows that physical activity had a significant positive regression effect on self-control (standardized regression coefficient β = 0.234, p < 0.001), a significant negative regression effect on mobile phone addiction (β = –0.286, p < 0.001), and a significant negative regression effect on sleep quality (β = –0.351, p < 0.001). Further, a chain mediation model of physical activity → self-control → mobile phone addiction → sleep quality was proposed. The findings provide basic data for college students to promote physical activity and improve sleep quality.

We show that existing RNA-seq, DNase-seq, and ChIP-seq data exhibit overdispersed per-base read count distributions that are not matched to existing computational method assumptions. To compensate for this overdispersion we introduce a nonparametric and universal method for processing per-base sequencing read count data called Fixseq. We demonstrate that Fixseq substantially improves the performance of existing RNA-seq, DNase-seq, and ChIP-seq analysis tools when compared with existing alternatives.

This data collection provides information about topics and issues of concern in research and policy within the field of corrections. Chief among these are the characteristics of persons confined to state prisons, their current and past offenses, and the circumstances or conditions of their confinement. Also included is extensive information on inmates' drug and alcohol use, program participation, and the victims of the inmates' most recent offenses. This information, which is not available on a national basis from any other source, is intended to assist the criminal justice community and other researchers in analysis and evaluation of correctional issues.
The Annual Prison Performance Ratings are published to ensure transparency of the final performance assessments of both public sector and privately-managed prisons across England and Wales.
Due to the impact of COVID-19 on prison delivery during the year and impact on data reliability, a data-informed, rather than data-driven, assessment took place in 2021/22 to identify the rating for each prison. A two-tier rating system is used for 2021/22 performance ratings, where prisons have been rated as either having:
