The proportion of elderly SSI recipients aged 70 or older has been growing in recent years, perhaps because of rising life expectancies overall and a higher incidence of poverty among the oldest old. In 1999, 84 percent of all elderly SSI recipients were 70 or older. This article examines Supplemental Security Income (SSI) eligibility and participation among the oldest old. The analysis was based on 1993 data from the Study of Assets and Health Dynamics Among the Oldest Old that were used to build a detailed SSI eligibility model to identify individuals who meet the federal criteria for SSI income and resource eligibility. The participation rate among those eligible for federal SSI benefits is 53.9 percent, which is generally consistent with the findings of other studies. Furthermore, eligible participants would receive a significantly higher federal SSI benefit than eligible nonparticipants. Correspondingly, eligible participants have significantly lower incomes and assets than eligible nonparticipants. An econometric model is used to estimate the influence of various demographic, financial, and health care use characteristics on the probability of SSI participation among eligible individuals and couples. The model corrects for measurement error in calculated benefits and for misclassifying someone as ineligible. The empirical results show that the effect of higher SSI benefits on the probability of participation is substantial--a $100 increase in benefits would increase the probability of participating for an average eligible unit by 15 percentage points. Many of the demographic, financial, and health care use variables also are important predictors of SSI participation among the oldest old. The eligibility and participation models are also used to simulate the effect of increasing the SSI unearned income disregard from $20 to $125. Those made eligible by this policy change would receive a very low federal SSI benefit on average, suggesting that they are on the margin of eligibility under the original program rules. The simulated participation rate is 48.8 percent--5 percentage points lower than under the original program rules--reflecting the low benefit that new eligibles would receive. Only 36 percent of those made eligible by the new program rules are predicted to participate. These SSI eligibility and participation models are potentially useful tools for policy analysis. It is fairly straightforward to use these models to change a feature of SSI eligibility, reestimate the group of eligible individuals and couples, and predict participation among those who are eligible under the simulated program rules. New eligibles can be compared with those eligible under original program rules. New participants can be compared with old participants. Although these models focus only on individuals aged 70 or older, this type of analysis can be helpful in estimating the potential distributional effects of proposed SSI policy changes. 相似文献

At Westminster, there are increasing pressures on select committees to publish in‐house legal advice. We suggest that examining the process of deciding to publish provides useful insights into the provision, reception, and use of legal advice, and the dynamics of select committees generally. We argue that the autonomy of select committees to decide what use they make of evidence and advice they receive is, in practice, constrained by the intra‐institutional dynamics and practices of select committees. Committee actors – parliamentarians, clerks, and parliamentary lawyers – each have overlapping, sometimes competing, roles. Most of the time, these roles and the responsibilities they encompass coincide, but the prospect of publication reveals clear tensions between the different actors. This is the politics of publication: the tactical approach of politicians is in tension with the stewardship of clerks and the professional norms of parliamentary lawyers. We suggest this tension will only increase in the near future. 相似文献

Human provenance studies employing isotopic analysis have become an essential tool in forensic and archaeological sciences, with multi-isotope approaches providing more specific location estimates compared to single isotope studies. This study reports on the human provenancing capability of neodymium isotopes (143Nd/144Nd), a relatively conservative tracer in the environment. Neodymium isotope ratios have only recently been determined on human remains due to low concentrations in human dental enamel (ppb range), requiring thermal ionisation mass spectrometry (TIMS) using 1013 Ω resistors. Dental elements (third molars) from 20 individuals born and raised in the Netherlands were analysed for Nd concentration (n = 12) and Nd isotope ratios (n = 15). The geological control on Nd isotope composition was examined using coupled Nd-Sr isotope analysis of the same third molar. Teeth from different geological environments were also analysed (Caribbean, Columbian, and Icelandic, n = 5). Neodymium elemental concentrations in dental elements ranged between 0.1 and 7.9 ppb (median 0.5 ppb). The Dutch 143Nd/144Nd ratios of the provinces of Limburg and Friesland were between 0.5118 and 0.5121, with Dutch 87Sr/86Sr ratios in agreement with the previously established local range (0.708–0.710). The current findings were compared to previously published results on Nd concentration and composition from Dutch individuals. The concentration of Nd and 143Nd/144Nd ratios were weakly correlated (R2 = 0.47, n = 17) in Dutch human dental enamel. The majority (n = 25, 83.3%) of individuals had Nd and Sr isotope values isotopically indistinguishable from the geological environment in which their third molars formed and mineralised. However, the Nd isotope ratios of the Icelandic individual and several Dutch individuals (n = 4) suggested that Nd in enamel is not solely influenced by geological environment. In order for neodymium isotopes to be quantitatively applied in forensic and archaeological settings further analyses of individuals from various geographical regions with well-defined dietary Nd isotope data are required. 相似文献

Our aim was to investigate whether early detection was feasible in prison and whether it could improve mental health outcomes in young prisoners. A secondary aim was to explore whether it can reduce returns to prison. Between 2011 and 2014, a total of 2115 young prisoners were screened, 94 (4.4%) met criteria for ultra-high risk for psychosis and were offered an intervention, 52 actually received it. Return to prison data were sought on the 52 participants, receiving a formal intervention. Of the 52 prisoners who received an intervention, 30.8% returned to custody compared to national average reconviction rates of between 45.4 and 66.5%. Our results suggest that early detection is a feasible option in a prison setting, improving mental health outcomes and reducing returns to prison. Mental health outcomes were recorded for a sub-sample of those receiving the intervention. The results indicated statistically significant improvements on measures of depression, anxiety and psychological distress. 相似文献

The changing nature of the transition to adulthood in western societies, such as the United States, may be extending the length
of time parents are engaged in “parenting” activities. However, little is known about different approaches parents take in
their interactions with their emerging-adult children. Hence, this study attempted to identify different clusters of parents
based on the extent to which they exhibited both extremes of control (psychological control, punishment, verbal hostility,
indulgence) and responsiveness (knowledge, warmth, induction, autonomy granting), and to examine how combinations of parenting
were related to emerging adult children’s relational and individual outcomes (e.g. parent–child relationship quality, drinking,
self-worth, depression). The data were collected from 403 emerging adults (M age = 19.89, SD = 1.78, range = 18–26, 62% female) and at least one of their parents (287 fathers and 317 mothers). Eighty-four
percent of participants reported being European American, 6% Asian American, 4% African American, 3% Latino, and 4% reported
being of other ethnicities. Data were analyzed using hierarchical cluster analysis, separately for mothers and fathers, and
identified three similar clusters of parents which we labeled as uninvolved (low on all aspects of parenting), controlling-indulgent (high on both extremes of control and low on all aspects of responsiveness), and authoritative (high on responsiveness and low on control). A fourth cluster was identified for both mothers and fathers and was labeled
as inconsistent for mothers (mothers were above the mean on both extremes of control and on responsiveness) and average for fathers (fathers were at the mean on all eight aspects of parenting). The discussion focuses on how each of these clusters
effectively distinguished between child outcomes. 相似文献

Accurate DNA quantification is essential for optimizing DNA testing and minimizing sample consumption. Real-time quantitative polymerase chain reaction (qPCR) assays have been published for human and canine nuclear DNA, and the need for quantifying other forensically important species was evident. Following the strategy employed for the canine qPCR assay, we developed individual assays to accurately quantify feline, bovine, equine, and cervid nuclear DNA. Each TaqMan-based assay incorporates a genus-specific probe targeting the Melanocortin-1 Receptor gene and includes a piece of synthetic DNA that acts as an internal PCR control for detecting inhibition. Developmental validations were carried out following the revised guidelines of the Scientific Working Group on DNA Analysis Methods with modifications necessary for validation of nonhuman qPCR assays. All assays demonstrated the specificity, sensitivity, stability, reproducibility, accuracy, and precision required for forensic casework. The application of these assays to animal forensic DNA analysis has both conserved laboratory resources and improved genotyping results. 相似文献

Approximately 81.7 million cats are in 37.5 million U.S. households. Shed fur can be criminal evidence because of transfer to victims, suspects, and/or their belongings. To improve cat hairs as forensic evidence, the mtDNA control region from single hairs, with and without root tags, was sequenced. A dataset of a 402-bp control region segment from 174 random-bred cats representing four U.S. geographic areas was generated to determine the informativeness of the mtDNA region. Thirty-two mtDNA mitotypes were observed ranging in frequencies from 0.6-27%. Four common types occurred in all populations. Low heteroplasmy, 1.7%, was determined. Unique mitotypes were found in 18 individuals, 10.3% of the population studied. The calculated discrimination power implied that 8.3 of 10 randomly selected individuals can be excluded by this region. The genetic characteristics of the region and the generated dataset support the use of this cat mtDNA region in forensic applications. 相似文献

Despite the growing research in the area of stalking, the focus has been on adults who engage in this behavior. Unfortunately, almost no studies investigate the prevalence of this behavior in adolescents. Two cases are presented demonstrating not only that stalking occurs during the period of adolescence, but also that there is a significant difference in the motivation underlying this behavior that can be classified similarly to that of adult stalkers. Further, a suggested classification based on these two cases as well as our experience with other juveniles who have exhibited stalking behaviors is proposed. The first case involves a narcissistic youth who also possesses psychopathic traits, while the second involves a lonely, severely socially awkward teen. Juvenile stalking is a societal problem that has not yet garnered the attention it deserves, and all systems that deal with juvenile delinquency (juvenile court, law enforcement, and mental health personnel) as well as the school system must be educated to the prevalence and severity of this yet-to-be-recognized problem. 相似文献
