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

Juvenile age estimation methods used in forensic anthropology generally lack methodological consistency and/or statistical validity. Considering this, a standard approach using nonparametric Multivariate Adaptive Regression Splines (MARS) models were tested to predict age from iliac biometric variables of male and female juveniles from Marseilles, France, aged 0–12 years. Models using unidimensional (length and width) and bidimensional iliac data (module and surface) were constructed on a training sample of 176 individuals and validated on an independent test sample of 68 individuals. Results show that MARS prediction models using iliac width, module and area give overall better and statistically valid age estimates. These models integrate punctual nonlinearities of the relationship between age and osteometric variables. By constructing valid prediction intervals whose size increases with age, MARS models take into account the normal increase of individual variability. MARS models can qualify as a practical and standardized approach for juvenile age estimation. 相似文献

Many authors have written about issues related to privacy, legitimacy and efficiency in relation to CCTV systems in public space as a crime prevention strategy. Some have approached them separately; others have tried to come up with more comprehensive approaches. Few, however, have dealt with how such concerns have been put into practice by those who have to decide on the uptake of CCTV. This article considers some reflections on efficacy, legitimacy and privacy in relation to CCTV, as an introduction to the case of how the members of the Control Commission of Video surveillance Devices in Catalonia took these issues into consideration and interpreted the Law when deciding whether to approve a petition submitted by the City Council to install three cameras in Barcelona’s public space in 2003. It concludes by drawing some conclusions from the process, as a way to highlight the complexity of the policy process around surveillance in open, public spaces. 相似文献

The process of decomposition of bodies in the marine environment is poorly understood and almost nothing is currently known about the microorganisms involved. This study aimed to investigate the microbes involved in decomposition in the sea and to evaluate the potential use of marine bacterial succession for postmortem submersion interval (PMSI) estimation, for which there is currently no reliable method. Partial pig remains were completely submerged during autumn and winter and were regularly sampled to document marine bacterial colonisation and the changes in community composition over time. Five stages of decomposition were recognised, some of which exhibited characters specific for partial carrion. Marine bacteria rapidly colonised the submerged remains in a successional manner. Seasonal differences were observed for the rate of decomposition and also for several groups of colonising bacteria. Marine bacteria specific for particular PMSIs were identified. This study provides an insight into the involvement of saprophytic marine bacteria in the decomposition of mammalian remains in the sea and is the first to explore the use of marine bacterial colonisation and succession as a novel tool for PMSI estimation. We propose that with further study, marine bacterial succession will prove useful for determination of the length of time a body may have been immersed in a marine environment. 相似文献

The first jurisdictions in the world to introduce legislation regulating donor conception were Victoria (Australia) and Sweden in the 1980s. Under the Infertility (Medical Procedures) Act 1984 (Vic), donor-conceived people (aged 18 years and over), their parents (if children were under 18 years) and donors gained the right to apply for identifying information about each other. Information can only be given with the consent of each party. To date, over 3,500 donor-conceived children have been born in Victoria since the 1984 Victorian legislation was introduced (and enacted in 1988). The first 106 donor-conceived children under this legislation turned 18 in 2006 and many of them may not know that they are donor-conceived. The Infertility Treatment Authority, Victoria, conducted a public education campaign to provide information and support to people affected by the legislation. The campaign and services associated with donor registers have had a significant initial impact. 相似文献

Litigants before the US courts have frequently attempted toimprove their legal position by relying on the Charming Betsycanon of statutory interpretation under which statutes whichcan be interpreted consistently with international obligationsshould be so interpreted. The argument has effectively beenthat the canon should be permitted to provide the interfacebetween the World Trade Organization Agreements as interpretedby the World Trade Organization tribunals, and national statutesas interpreted by US executive agencies. The ease with whichthe canon can be stated belies the complexity and controversynow associated with its application. Some of the cases are arguablyirreconcilable while academic opinion is similarly polarizedby concerns about both the extent of judicial deference to agencyinterpretations, and about the slightest possibility of a moreinquisitive approach. This article discusses how the canon hasbeen applied and should be applied in domestic cases with aWorld Trade Organization dimension. A re-conceptualization ofthe canon's role in cases of this type is suggested. 相似文献

Abstract Traditionally the British legal system has taken a sceptical attitude toward the testimony of children, reflected in the competency requirement, the corroboration rule and the judicial caution. However, recent psychological research has suggested that children, properly interviewed, can provide invaluable testimony in securing convictions in cases of sexual or physical abuse. Research suggests that children's spontaneous accounts of events are generally accurate, and that suggestibility can be greatly reduced by appropriate questioning techniques. Partly as a result of such research, the legal hurdles surrounding children's evidence have been dismantled and procedural innovations, such as the use of the Videolink and videotaped interviews introduced. Empirical research demonstrates the success of the Videolink and a similar evaluation is planned for videotaped interviews. The latter has highlighted the need for a new research agenda which would include the impact of biased or repeated questioning, and requests to children from abusers to lie or keep secrets. 相似文献
