ABSTRACT

A large body of research has focused on understanding mass incarceration in the United States through the lens of federal and state prison growth. However, local jail systems, with 11 million admissions each year, have received less research attention despite their broad impact on communities. Preliminary analysis conducted by the Vera Institute of Justice (Vera) uncovered geographical disparities in county jail incarceration rates. Contrary to assumptions that incarceration is an urban phenomenon, Vera discovered that, in recent decades, pretrial jail rates have declined or remained flat in many urban areas, whereas rates have grown in rural counties. In an effort to uncover factors contributing to continued jail growth in rural areas, Vera joined forces with Two Sigma’s Data Clinic, a volunteer-based program that leverages Two Sigma employees’ data science expertise. Determinants of local jail rates from 2000–2013 were examined using a generalized estimating equations (GEE) model to account for correlations within counties over time. Results revealed that county-level poverty, police expenditures, and spillover effects from other county and state authorities are significant predictors of local jail rates. Investigation of model residuals revealed clusters of counties where observed rates were much higher than expected conditioned upon county variables.  相似文献

Worldwide, cities are investing in greenspace to enhance urban quality of life and conserve biodiversity. Cities should ensure these investments do not unintentionally result in ecosystem disservices. Municipal management decisions regarding urban greenspaces, such as mowing frequency, could influence mosquito communities and public health. We examined how mowing, resultant vegetation characteristics, and landscape context influenced adult mosquito abundance in urban vacant lots. We sampled adult Culex and Aedes mosquitoes in a network of vacant lots within eight Cleveland, Ohio, USA neighborhoods in 2015 and 2016 using CO2-baited light traps and grass-infused gravid traps. For each lot, we quantified vegetation characteristics, including plant diversity, bloom area, and biomass, as well as the surrounding landscape composition at radii of 60 and 1000 m. We found that periodic mowing did not significantly affect mosquito abundances. However, vacant lots with more diverse plant communities were associated with a greater light trap capture of both Culex and Aedes. Both mosquito genera declined in light trap catches with increased impervious surface at 60 m. Similarly, Culex (gravid trap) declined with the amount of built infrastructure at 1000 m. In contrast, Aedes (light trap) increased with the concentration of buildings in the landscape at 1000 m. Our findings indicate that reducing the frequency of mowing within vacant lots will not necessarily increase adult mosquito abundance. Nonetheless, mosquito surveillance and management should be considered when planning conservation-focused greenspaces, as vegetation design choices and the landscape context of a site do influence vector abundance and potentially disease risk.

A randomized controlled trial evaluated the effectiveness of a 4-wk extended theory of planned behavior (TPB) intervention to promote regular physical activity and healthy eating among older adults diagnosed with Type 2 diabetes or cardiovascular disease (N = 183). Participants completed TPB measures of attitude, subjective norm, perceived behavioral control, and intention, as well as planning and behavior, at preintervention and 1 wk and 6 wk postintervention for each behavior. No significant time-by-condition effects emerged for healthy eating. For physical activity, significant time-by-condition effects were found for behavior, intention, planning, perceived behavioral control, and subjective norm. In particular, compared with control participants, the intervention group showed short-term improvements in physical activity and planning, with further analyses indicating that the effect of the intervention on behavior was mediated by planning. The results indicate that TPB-based interventions including planning strategies may encourage physical activity among older people with diabetes and cardiovascular disease.  相似文献

The widespread introduction of electronic gaming machines (EGMs) in Australia has seen problem gambling (PG) rates soar over the past decade. This has been particularly apparent among women, with presentations to gambling help services increasing fivefold, and 90% of them indicating EGMs as the problem. Prisoners represent a group containing the highest PG rate found in any population. Despite a sharp increase in PG among women and the well-established link between offenders and PG, little data exists concerning PG among female prisoners. This study examined lifetime prevalence of PG among female prisoners in South Australia. The Early Intervention Gambling Health Test was administered to 74 female prisoners. Previous help-seeking behaviour and association with incarceration were also examined. Sixty-four percent of respondents indicated PG with one in six reporting they were incarcerated due to PG-related offending. Problem gamblers whose incarceration was related to PG were more likely to indicate they had gambled to try and win money to repay debts than problem gamblers incarcerated for unrelated offending. Given high levels of PG and overall low rates of help-seeking, women’s prisons may provide an opportunity to engage this high-risk population with effective treatment.  相似文献

ABSTRACT

Sexual assault is a major public health concern and college women are four times more likely to experience sexual assault than any other group. We investigated whether sexting is a mechanism by which alcohol use increases risk for college women to be targeted for sexual assault. We hypothesized that sexting would mediate the relationship between problem drinking and sexual assault, such that drinking (T1 = beginning fall semester) would contribute to increased sexting (T2 = end fall semester), and in turn increase the risk of being targeted for sexual assault (T3 = end spring semester). Results: Among 332 undergraduate women (M(SD)age = 19.15(1.69), 76.9% Caucasian), sexting (T2) predicted sexual assault (T3; b = 3.98, p = .05), controlling for baseline sexual assault (b = 0.82, p < .01). Further, sexting (T2) mediated the relationship between problem drinking (T1) and sexual assault (T3) (b = 0.04, CI[.004,.12]). Conclusion: Findings suggest that sexting is one mechanism through which drinking increases the risk of college women being targeted for sexual assault.  相似文献

Although much scholarly attention has been paid to the question of whether a “shortage” of adequate child care exists, few studies have framed this issue around the disjuncture between mothers' preferred modes of care and the types of care available to them. In this study, we address that gap by asking what mothers want, what mothers use, and why many don't use the form of care they prefer. Using a regional sample of 247 pregnant women who returned to paid employment within the 1st year postpartum and used nonmaternal child care, we found that the majority of the mothers surveyed preferred father care (53%), but only 23% primarily used father care. Derived from logistic regression models, the significant determinants of achieving the type of care preferred are the presence of additional children under age 5, higher educational attainment, and the mother working an evening or night work shift.  相似文献

OBJECTIVE: The authors developed a smoking cessation program using mobile phone text messaging to provide tailored and stage-specific messages to college smokers. PARTICIPANTS AND METHODS: The authors recruited 31 daily smokers who desired to quit from a college campus and asked them to use an Internet and mobile phone text messaging program to quit smoking. RESULTS: Six weeks after program initiation, 45% reported abstinence with 42% abstinent based on cotinine verification. Continued smokers reported significantly reduced smoking rates and dependence. Overall, participants accepted the text messages. CONCLUSIONS: These results replicate findings from an earlier study and indicate that mobile phone text messaging is a potentially efficacious and easily disseminated method for providing cessation interventions to young adult smokers.  相似文献

There is a general consensus among researchers and policymakers that matched savings programs can significantly increase the propensity to save among low-income households. This study offers a unique contribution to the field by testing whether principals and theories from behavioral economics affect the decisions that participants make in these savings programs. Using a sample of people participating in the $aveNYC program, a matched savings program for very low-income households, we test whether information failure, time preference, and financial hardship affected people's ability to complete the program and receive the match money. We find that future orientation does not significantly impact program completion, but both information failure and financial hardship increase the hazard of early account closure. Although the pool of participants who did not receive the match was small, both information failure and financial hardship had large impacts on the risk of withdrawing the account before receiving a match. We discuss how these findings can inform program design and suggest future research.  相似文献

In recent years, several attempts have been made to characterize the generalized Pareto distributions (GPD) based on the properties of order statistics and record values. In the present article, we give some characterization results on GPD based on order statistics and generalized order statistics. Some characterizations of uniform distribution based on expectation of some functions of order statistics are also given.  相似文献
