January 1, 1974, marked the beginning of the Supplemental Security Income (SSI) program for the aged, blind, and disabled, and also marked the end of a 14-month period of preparation that began on October 30, 1972, when President Nixon signed into law the Social Security Amendments of 1972 (Public Law 92-603). As a way of marking SSI's 10th anniversary, it seems appropriate to review the development of the program since its enactment and compare the program's performance with its original goals and expectations. This article looks at the SSI program in the context of the program's goals as set out by Congress and discusses the legislative changes--and the motives behind those changes--since its implementation. Statistical data are examined to determine whether the program is accomplishing what it was designed to do, and whether, as a result of legislation or because of changes in the characteristics of the recipient population, trends are developing that may have a future impact on the program.  相似文献

We examine the understudied link between mental/physical health problems and their relationship with perceived unsafety via higher levels of vulnerability. We examine this relationship by linking data at the individual-level, the neighborhood-level, and the county-level using the Portraits of American Life Survey (PALS). Using this data we examine the effect of individual and neighborhood conditions on perceived safety while controlling for county-level crime rates. Findings indicate that higher numbers of physical impairment and mental health issues are independently related to higher levels of perceived unsafety. Both mental and physical health problems are associated with higher levels of fear. These higher levels of vulnerability then directly contribute to higher levels of feeling of unsafety. Unlike past research, we find a mental health link to fear of crime that cannot be explained by physical impairments.  相似文献

The purpose of this research is to extend the existing media and crime literature by discussing how minority criminal justice personnel are granted or not granted intellectual authority in fictional crime dramas by their representation as presenters of crime and non-crime fact-based statements. An analysis of 117 episodes from four fictional crime dramas appearing in the top 20 Nielson ratings from 2003 to 2010 indicate that Black characters are not given the same intellectual authority as White characters, and therefore are imbued with less power and status than their White counterparts. In some cases, Black characters are not even given intellectual authority within their respective intellectual fields.  相似文献

Doping control laboratories accredited by the World Anti-Doping Agency (WADA) require criteria that allow endogenous steroids to be distinguished from their synthetic analogues in urine. Methodology based on "looking outside the metabolic box" was used in this study to identify diagnostic urinary markers of 4-androstenediol (4-ADIOL) administration. Androst-2,4-diene-17-one and androst-3,5-diene-17-one are proposed to be formed in urine from acid-catalyzed hydrolysis of 4-ADIOL sulfoconjugate, a major phase II metabolic product of 4-ADIOL. The presence of these markers in the routine gas chromatography-mass spectrometry (GC-MS) steroid screen was suitable to identify samples requiring confirmation by gas chromatography-combustion-isotope ratio mass spectrometry (GC-C-IRMS) - to measure the carbon isotope ratio (δ(13)C) of the androstdiene markers and confirm their likely synthetic origin based on depleted (13)C content.  相似文献

Purpose

A prominent explanation of why certain groups of people fear crime more than others focuses on physical and social vulnerability. Some researchers have argued that physical vulnerability characteristics (e.g., gender, age, health) are more important in determining one's fear of crime while others have argued that social vulnerability characteristics (e.g., race and socioeconomic status) are more important.

Methods

We test the independence of the physical and social vulnerability characteristics through a nationally representative sample of Americans. Using a multilevel path modeling approach, we examine whether the physical or the social vulnerability explanation is more powerful in its explanation, or whether a combination of both vulnerabilities explains fear of crime.

Results

Results suggest that the two explanations are interdependent to some degree; with the direct effects of social vulnerability being most tied to physical indicators of vulnerability through indirect effects. To a lesser degree, the direct effects of physical vulnerability are also tied to fear of crime indirectly through indicators of social vulnerability.

Conclusions

The implications of these results are discussed.  相似文献

A simple means of detecting the abuse of steroids that also occur naturally is a problem facing doping control laboratories. Specific markers are required to allow the detection of the administration of these steroids. These markers are commonly measured using a set of data obtained from the screening of samples by gas chromatography-mass spectrometry (GC-MS). Doping control laboratories further need to confirm identified abuse using techniques such as gas chromatography-combustion-isotope ratio mass spectrometry (GC-C-IRMS). An interesting urinary species was found while following the pharmacokinetics and changes to the steroid profile from single and multiple oral doses of the International Olympic Committee/World Anti Doping Agency (IOC/WADA) prohibited substance, dehydroepiandrosterone (DHEA). The urine samples collected from the administration studies were subject to GC-MS and GC-C-IRMS steroid analysis following cleanup by solid phase extraction techniques. A useful urinary product of DHEA administration was detected in the urine samples from each of the administration studies and was identified by GC-MS experiments to be 3alpha,5-cyclo-5alpha-androstan-6beta-ol-17-one (3alpha,5-cyclo). This compound occurs naturally but the concentrations of 3alpha,5-cyclo were elevated following both the single DHEA administration (up to 385 ng/mL) and multiple DHEA administrations (up to 1240 ng/mL), in relation to those observed prior to these administrations (70 and 80 ng/mL, respectively). A reference distribution of urine samples collected from elite athletes (n = 632) enabled the natural concentration range of 3alpha,5-cyclo to be established (0-280 ng/mL), with a mean concentration of 22 ng/mL. Based on this an upper 3alpha,5-cyclo concentration limit of 140 ng/mL is proposed as a GC-MS screening marker of DHEA abuse in athletes. GC-C-IRMS analysis revealed significant 13C depletion of 3alpha,5-cyclo following DHEA administration. In the single administration study, the delta13C value of 3alpha,5-cyclo changed from -24.3 per thousand to a minimum value of -31.1 per thousand at 9 h post-administration, before returning to its original value after 48 h. The multiple administration study had a minimum delta13C 3alpha,5-cyclo of -33.9 per thousand during the administration phase in contrast to the initial value of -24.2 per thousand. Preliminary studies have shown 3alpha,5-cyclo to most likely be produced from DHEA sulfate found at high levels in urine. The complementary use of GC-MS and GC-C-IRMS to identify new markers of steroid abuse and the application of screening criteria incorporating such markers could also be adapted by doping control laboratories to detect metabolites of androstenedione, testosterone and dihydrotestosterone abuse.  相似文献

Minimal attention has been focused on difficulties for youth in residential care regarding building healthy dating relationships, despite the significant risks to this group of adolescents. This study provided a unique opportunity to conduct focus groups with youth in residential care on issues surrounding dating relationships. The majority of youth feedback centered on the themes of desiring support developing relationship boundaries, establishing trust in relationships, understanding the consequences of sexual activity, and having real world examples regarding dating relationships. The data were examined for differences between the genders and recommendations for next steps provided.  相似文献

Aftercare services have been suggested to improve reintegration for youth departing residential care programs. The purpose of this study was to collect views from legal professionals about the challenges youth and families face during reintegration and solutions to improve stability. Views were collected from 14 legal professionals (e.g., guardian ad litem, legal counsel) through a survey and 90‐minute nominal group technique focus group. Results indicated parent expectations about re‐entry and lack of services, supports and resources were challenges. Solutions suggested by participants included family, mental health and educational supports, and transition planning. Study limitations and future implications are discussed.  相似文献
