A Guide to Disability Statistics from the Survey of Income and Program Participation

This paper discusses the utility of the SIPP in disability analyses, including a summary of descriptive statistics on people with disabilities from multiple SIPP panels, including the most recent SIPP panel (2001). The findings provide insights into the various health, employment, income, and program participation outcomes that may be associated with different definitions of disability and illustrates the potential for using SIPP data in further disability analyses. Our descriptive findings highlight the differences in the demographic composition and outcomes across disability definitions, underscoring the importance of carefully selecting an appropriate disability conceptualization in generating disability statistics

Semidefinite relaxations for semi-infinite polynomial programming

This paper studies how to solve semi-infinite polynomial programming (SIPP) problems by semidefinite relaxation method. We first introduce two SDP relaxation methods for solving polynomial optimization problems with finitely many constraints. Then we propose an exchange algorithm with SDP relaxations to solve SIPP problems with compact index set. At last, we extend the proposed method to SIPP problems with noncompact index set via homogenization. Numerical results show that the algorithm is efficient in practice.Comment: 23 pages, 4 figure

The Measurement of Medicaid Coverage in the SIPP: Evidence from California, 1990-1996

This paper studies the accuracy of reported Medicaid coverage in the Survey of Income and Program Participation (SIPP) using a unique data set formed by matching SIPP survey responses to administrative records from the State of California. Overall, we estimate that the SIPP underestimates Medicaid coverage in the California population by about 10 percent. Among SIPP respondents who can be matched to administrative records, we estimate that the probability someone reports Medicaid coverage in a month when they are actually covered is around 85 percent. The corresponding probability for low-income children is even higher - at least 90 percent. These estimates suggest that the SIPP provides reasonably accurate coverage reports for those who are actually in the Medicaid system. On the other hand, our estimate of the false positive rate (the rate of reported coverage for those who are not covered in the administrative records) is relatively high: 2.5 percent for the sample as a whole, and up to 20 percent for poor children. Some of this is due to errors in the recording of Social Security numbers in the administrative system, rather than to problems in the SIPP.

The Measurement of Medicaid Coverage in the SIPP : Evidence from a Comparison of Matched Records

This paper studies the accuracy of reported Medicaid coverage in the Survey of Income and Program Participation (SIPP) using a unique data set formed by matching SIPP survey responses to administrative records from the State of California. Overall, we estimate that the SIPP underestimates Medicaid coverage in the California population by about 10 percent. The probability that a SIPP respondent who is covered by Medicaid in a given month correctly reports their coverage is around 85 percent. The corresponding probability for low-income children is higher – around 90 percent. Under-reporting by those who are actually in the Medicaid system is partially offset by over-reporting of coverage by people who are not. Some of these false positive responses are attributable to errors and missing data in the administrative system, rather than to problems in the SIPP. Taking account of these errors, the estimated false positive rate for the population as a whole is about 1.5 percent, and 4-5 percent for poor children.

Revisiting Bounded-Suboptimal Safe Interval Path Planning

Safe-interval path planning (SIPP) is a powerful algorithm for finding a path in the presence of dynamic obstacles. SIPP returns provably optimal solutions. However, in many practical applications of SIPP such as path planning for robots, one would like to trade-off optimality for shorter planning time. In this paper we explore different ways to build a bounded-suboptimal SIPP and discuss their pros and cons. We compare the different bounded-suboptimal versions of SIPP experimentally. While there is no universal winner, the results provide insights into when each method should be used

The cyclicality of worker flows: new evidence from the SIPP

Drawing on CPS data, the authors show that total monthly job loss and hiring among U.S. workers, as well as job loss hazard rates, are strongly countercyclical, while job finding hazard rates are strongly procyclical. They also find that total job loss and job loss hazard rates lead the business cycle, while total hiring and job finding rates trail the cycle. In the current paper the authors use information from the Survey on Income and Program Participation (SIPP) to reevaluate these findings. SIPP data are used to construct new longitudinally consistent gross flow series for U.S. workers, covering 1983-2003. The results strongly validate the authors' findings, with two important exceptions: (1) total hiring leads the cycle in the SIPP data, and (2) the job loss rate is substantially more volatile than the job finding rate at business cycle frequencies.

Real Trends or Measurement Problems? Disability and Employment Trends from the Survey of Income and Program Participation

This paper addresses important concerns in using statistical data to track outcomes of people with disabilities and provides new evidence of employment trends of people with disabilities using alternative disability conceptualizations from the Survey of Income and Program Participation (SIPP). This analysis comes at an important time because some researchers have criticized the data and definitions used to measure these trends. At the extreme, some have concluded that such analyses should cease because of major limitations in measuring disability that exists in current surveys (especially the SIPP). Because the SIPP has been used extensively to examine outcomes of people with disabilities, it is important to understand these data criticisms and test whether the trends from the SIPP mirror those in other data sources. We conclude that the different empirical results found by researchers are not caused by "problems" with the data but rather with the assumptions researchers make when using the data. We illustrate the importance of exercising caution when developing disability questions and measuring disability trends in existing data sources. While some measures of limitations may be problematic, we find that the relatively broad measures used in several disability studies provide reasonable estimations of important subgroups of people with disabilities. We also show that the timing and structure of specific questions affects disability prevalence rates and influences observed outcomes. When we use comparable definitions across panels, we consistently find that employment rates of men with disabilities have fallen from 1990 to 1996 and employment rates of women with disabilities have remained flat. The consistency of these findings across a variety of measures illustrates an important and disturbing trend of downward employment rates for people with disabilities. These findings are particularly disturbing because they suggest that the gap in employment rates between those with and without disabilities is growing

Mat á alvarleika persónuleikavandamála : athugun á spurningalistanum Severity Indices of Personality Problems (SIPP) í úrtaki íslenskra háskólanema

Neðst á síðunni er hægt að nálgast greinina í heild sinni með því að smella á hlekkinn View/OpenSpurningalistinn Severity Indices of Personality Problems eða SIPP er nýr spurningalisti sem metur alvarleika vandamála sem oft tengjast persónuleikaröskunum. Listinn er til í tveimur útgáfum og inniheldur önnur 118 atriði (SIPP- 118) sem skiptast á alls 16 undirþætti sem tilheyra fimm yfirþáttum. Hin útgáfan er styttri og inniheldur 60 atriði (SIPP-60) sem notuð eru til að reikna út skor þátttakenda á yfirþáttunum fimm. Tilgangur þessarar rannsóknar var að kanna próffræðilega eiginleika íslenskrar þýðingar á SIPP listunum í úrtaki 634 háskólanema. Niðurstöður sýndu að áreiðanleiki 13 af 16 undirþáttum SIPP-118 var ásættanlegur eða góður ( 0,70). Í leitandi þátttagreiningu voru þrír af fimm þáttum sambærilegir við niðurstöður erlendrar rannsóknar á SIPP-118. Skor á yfirþáttum SIPP-60 höfðu miðlungs til sterka fylgni við skor á spurningalista um lífsánægju þannig að meiri alvarleiki persónuleikavanamála tengdist minni lífsánægju. Marktækur munur var á meðaltölum á öllum yfirþáttum SIPP-60 milli hópa sem höfðu lág, miðlungs eða há skor á skimunarlista fyrir persónuleikaraskanir. Fyrstu niðurstöður á íslenskri þýðingu SIPP spurningalistans benda til að próffræðilegir eiginleikar listans séu góðir en kanna þarf betur þátttabyggingu listans.

Any-Angle Pathfinding for Multiple Agents Based on SIPP Algorithm

The problem of finding conflict-free trajectories for multiple agents of identical circular shape, operating in shared 2D workspace, is addressed in the paper and decoupled, e.g., prioritized, approach is used to solve this problem. Agents' workspace is tessellated into the square grid on which any-angle moves are allowed, e.g. each agent can move into an arbitrary direction as long as this move follows the straight line segment whose endpoints are tied to the distinct grid elements. A novel any-angle planner based on Safe Interval Path Planning (SIPP) algorithm is proposed to find trajectories for an agent moving amidst dynamic obstacles (other agents) on a grid. This algorithm is then used as part of a prioritized multi-agent planner AA-SIPP(m). On the theoretical, side we show that AA-SIPP(m) is complete under well-defined conditions. On the experimental side, in simulation tests with up to 200 agents involved, we show that our planner finds much better solutions in terms of cost (up to 20%) compared to the planners relying on cardinal moves only.Comment: Final version as submitted to ICAPS-2017 (main track); 8 pages; 4 figures; 1 algorithm; 2 table
