Option Value And Dynamic Programming Model Estimates Of Social Security Disability Insurance Application Timing, Rickard V. Burkhauser, J. S. Butler, Gulcin Gumus

Economics - All Scholarship

This paper develops dynamic structural models - an option value model and a dynamic programming model - of the Social Security Disability Insurance (SSDI) application timing decision. We estimate the time to application from the point at which a health condition first begins to affect the kind or amount of work that a currently employed person can do. We use Health and Retirement Study (HRS) and restricted access Social Security earnings data for estimation. Based on tests of both in-sample and out-of-sample predictive accuracy, our option value model performs better than both our dynamic programming model and our reduced form …

Dynamic Modeling Of The Ssdi Application Timing Decision: The Importance Of Policy Variables, Rickard V. Burkhauser, J S. Butler, Gulcin Gumus

Economics - All Scholarship

This paper analyzes the importance of policy variables in the context of Social Security Disability Insurance (SSDI) application timing decision. Previously, we explicitly modeled the optimal timing of SSDI application using dynamic structural models. We estimated these models using data from the Health and Retirement Study (HRS). This paper uses option value model estimates to simulate application timing under alternative SSDI policy formulations. We consider changes in three policy variables: benefit levels, acceptance rates, and employer accommodation. Our simulations suggest all these changes would have substantial effects on expected spell lengths until application and on lifetime application rates, and hence …

Staff publications, research, and presentations

The Michel Orradre Library at Santa Clara University in California suffered from a recurring influx of dirty groundwater into its basement, from 1997–2001. A report on this library's flooding problem, its approach to the problem, and lessons learned from the experience is provided.

Medical Necessity In Private Health Plans: Implications For Behavioral Health Care, Sara J. Rosenbaum, Brian Kamoie, D. Richard Mauery, Brian Walitt

Health Policy and Management Faculty Publications

This report addresses how the term "medical necessity" is defined in private health insurance coverage decisions. It summarizes a review of the literature, an extensive review of legal cases that challenge insurer decisions, materials prepared by the insurance industry, consultation with experts in the field, a review of investigations conducted by State departments of insurance and attorneys general, and interviews with health care executives regarding the decision-making process itself. The report does not explore factors that can affect access to care that might be considered clinically necessary by treating professionals or the effects of medical necessity decisions on therapeutic outcomes.

The Epidemiology Of U.S. Immunization Law: A National Study For The National Immunizations Program, Centers For Disease Control And Prevention: Medicaid Coverage Of Immunizations For Non-Institutionalized Adults, Sara J. Rosenbaum, Alexandra M. Stewart, Marisa A. Cox, Alexis Lee

Health Policy and Management Faculty Publications

As a health policy matter, coverage of immunizations and their administration for all ages at levels recommended by the Advisory Committee on Immunization Practices (ACIP) has grown in importance for several reasons: 1) the growing attention to both manmade and naturally occurring public health threats; 2) recognition of the value of immunization to society; and 3) the relatively high cost of at least certain immunization services in relation to personal income. No population stands to benefit more from immunization coverage than low income persons.

Studies suggest that adult immunization status is particularly low, and that financial barriers play a role, …

Internet Sex Crimes Against Minors: The Response Of Law Enforcement., Janis Wolak, Kimberly J. Mitchell, David Finkelhor

Crimes Against Children Research Center

The Internet1 and computers have come to play a growing role in sex crimes that are committed against children and youth.2 Since the mid-1990s these developing technologies have posed challenges for law enforcement requiring them to confront situations not anticipated in criminal statutes, master technical advances, develop new investigative techniques, and handle criminal cases that often span multiple jurisdictions. To assist, legislators have acted on a number of fronts creating new statutes that encompass Internet offenses, stiffening penalties, and creating a national clearinghouse for reports of Internet-related crimes against children and the CyberTipline® operated by the National Center for Missing …

Maine Folklife, Vol. 9, Iss. 2, Maine Folklife Center

Maine Folklife Center Newsletter

Once again, folklorist Edward D. Sandy Ives has been recognized by his peers for his outstanding work. This time he received the Kenneth Goldstein Award for Lifetime Academic Leadership at the American Folklore Society meetings in New Mexico October, 2003. In presenting the award to Sandy Ives, Lee Haring remarked that he had known both Sandy and Kenny Goldstein for many years. He imagined what Kenny would have said if he'd been told an award was to be given to Sandy. He concluded that Kenny would have shouted, at the top of his lungs, "OF COURSE!"

Art For Democracy's Sake? Group Membership And Political Engagement In Europe, Todd Donovan, Shaun Bowler, Robert Hanneman

Political Science Faculty Publications

Theorists contend that private social groups-particularly those that have no overt political missions such as bowling leagues, sports clubs, and choral societies-make major contributions to democracy by generating engagement with democracy in the form of political interest and participation. Although this discussion is generally at an aggregate level, it is based on seldom-tested assumptions about individual-level phenomena. This study expands our understanding of how (and where) memberships in various groups are associated with political engagement of individual citizens. We test if the effects of group membership vary across eleven European democracies and test which types of groups have the strongest …

Online Issues Are Global, Carol Tenopir

School of Information Sciences -- Faculty Publications and Other Works

THE INFORMATION INDUSTRY is international. With major English-language online publishers based in the Netherlands, Germany, and Canada (not to mention Alabama and New York), the information you lease may be generated and designed anywhere in the world. Likewise, the issues and challenges facing libraries as they move to large-scale digital collections are global in nature.

Conferences about digital libraries are also international; in September I attended "Digilib: Towards a User-Centered Approach to Digital Libraries" in Finland. Two hundred attendees from over 20 countries discussed how to gather user information for the purpose of designing more useful digital libraries. Sessions were …

Alcohol And Anxiety: Subtle And Obvious Attributes Of Abuse In Adults With Social Anxiety Disorder And Panic Disorder, Lindsay S. Ham, Debra A. Hope

Department of Psychology: Faculty Publications

Previous research has found a relation between social anxiety disorder and alcoholism, but recent work found no differences in drinking levels among socially anxious individuals, dysthymics, and normal controls. Using a more sophisticated measure of substance abuse may further explicate the relation between social anxiety and drinking. We examined aspects of substance abuse in treatment-seeking individuals with social anxiety disorder or panic disorder (psychiatric control group) as well as nondisordered individuals (normal control group). We used the Substance Abuse Subtle Screening Inventory–3 because it includes both face valid and subtle items to control for social desirability. Contrary to the hypotheses, …

A Behavioral Model Of Bargaining With Endogenous Types, Dilip Abreu, David G. Pearce

Cowles Foundation Discussion Papers

We enrich a simple two-person bargaining model by introducing “behavioral types” who concede more slowly than does the average person in the economy. The presence of behavioral types profoundly influences the choices of optimizing types. In equilibrium, concessions are calculated to induce “reciprocity”: a substantial concession by player i is followed by a period in which j is much more likely to make a concession than usual. This favors concessions by i that are neither very small nor large enough to end the bargaining immediately. A key difference from the traditional method of perturbing a game is that the actions …

Societal Stability And Political Reform : Chinese Politics In The 1990s, Yiu Chung Wong

CAPS Working Paper Series

On 28 September 1995, Jiang Zemin delivered one of the most important speeches in his tenure as the General Secretary of the CCP in the Fifth Plenum of 14th CCP Congress, which is entitled “To Handle Correctly Certain Relationships in the Process of Socialist Modernization Construction”. On the top of the agenda was the relationships between reform, development and stability. To him, reform, in particular economic reform, must be pursued; development is the enhancing of national strength and stability is the pre-condition of development. Indeed, it is the equilibrium of these three sets of relationships that the CCP leadership strove …

P* Index Of Segregation: Distribution Under Reassignment, Charles F. Bond, F. D. Richard

Journal of Modern Applied Statistical Methods

Students of intergroup relations have measured segregation with a P^* index. In this article, we describe the distribution of this index under a stochastic model. We derive exact, closed-form expressions for the mean, variance, and skewness of P^* under random segregation. These yield equivalent expressions for a second segregation index: η². Our analytic results reveal some of the distributional properties of these indices, inform new standardizations of the indices, and enable small-sample significance testing. Two illustrative examples are presented.

A Critical Examination Of The Use Of Preliminary Tests In Two-Sample Tests Of Location, Kimberly T. Perry

Journal of Modern Applied Statistical Methods

This paper explores the appropriateness of testing the equality of two means using either a t test, the Welch test, or the Wilcoxon-Mann-Whitney test for two independent samples based on the results of using two classes of preliminary tests (i.e., tests for population variance equality and symmetry in underlying distributions).

Confidence Intervals For P(X Less Than Y) In The Exponential Case With Common Location Parameter, Ayman Baklizi

Journal of Modern Applied Statistical Methods

The problem considered is interval estimation of the stress - strength reliability R = P(Xθ and λ respectively and a common location parameter μ . Several types of asymptotic, approximate and bootstrap intervals are investigated. Performances are investigated using simulation techniques and compared in terms of attainment of the nominal confidence level, symmetry of lower and upper error rates, and expected length. Recommendations concerning their usage are given.

Approximate Bayesian Confidence Intervals For The Variance Of A Gaussian Distribution, Vincent A. R. Camara

Journal of Modern Applied Statistical Methods

The aim of the present study is to obtain and compare confidence intervals for the variance of a Gaussian distribution. Considering respectively the square error and the Higgins-Tsokos loss functions, approximate Bayesian confidence intervals for the variance of a normal population are derived. Using normal data and SAS software, the obtained approximate Bayesian confidence intervals will then be compared to the ones obtained with the well known classical method. The Bayesian approach relies only on the observations. It is shown that the proposed approximate Bayesian approach relies only on the observations. The classical method, that uses the Chi-square statistic, does …

Random Regression Models Based On The Elliptically Contoured Distribution Assumptions With Applications To Longitudinal Data, Alfred A. Bartolucci, Shimin Zheng, Sejong Bae, Karan P. Singh

Journal of Modern Applied Statistical Methods

We generalize Lyles et al.’s (2000) random regression models for longitudinal data, accounting for both undetectable values and informative drop-outs in the distribution assumptions. Our models are constructed on the generalized multivariate theory which is based on the Elliptically Contoured Distribution (ECD). The estimation of the fixed parameters in the random regression models are invariant under the normal or the ECD assumptions. For the Human Immunodeficiency Virus Epidemiology Research Study data, ECD models fit the data better than classical normal models according to the Akaike (1974) Information Criterion. We also note that both univariate distributions of the random intercept and …

Type I Error Rates Of Four Methods For Analyzing Data Collected In A Groups Vs Individuals Design, Stephanie Wehry, James Algina

Journal of Modern Applied Statistical Methods

Using previous work on the Behrens-Fisher problem, two approximate degrees of freedom tests, that can be used when one treatment is individually administered and one is administered to groups, were developed. Type I error rates are presented for these tests, an additional approximate degrees of freedom test developed by Myers, Dicecco, and Lorch (1981), and a mixed model test. The results indicate that the test that best controls the Type I error rate depends on the number of groups in the group-administered treatment. The mixed model test should be avoided.

A Nonparametric Fitted Test For The Behrens-Fisher Problem, Terry Hyslop, Paul J. Lupinacci

Journal of Modern Applied Statistical Methods

A nonparametric test for the Behrens-Fisher problem that is an extension of a test proposed by Fligner and Policello was developed. Empirical level and power estimates of this test are compared to those of alternative nonparametric and parametric tests through simulations. The results of our test were better than or comparable to all tests considered.

Example Of The Impact Of Weights And Design Effects On Contingency Tables And Chi-Square Analysis, David A. Walker, Denise Y. Young

Journal of Modern Applied Statistical Methods

Many national data sets used in educational research are not based on simple random sampling schemes, but instead are constructed using complex sampling designs characterized by multi-stage cluster sampling and over-sampling of some groups. Incorrect results are obtained from statistical analysis if adjustments are not made for the sampling design. This study demonstrates how the use of weights and design effects impact the results of contingency tables and chi-square analysis of data from complex sampling designs.

Comparison Of Viral Trajectories In Aids Studies By Using Nonparametric Mixed-Effects Models, Chin-Shang Li, Hua Liang, Ying-Hen Hsieh, Shiing-Jer Twu

Journal of Modern Applied Statistical Methods

The efficacy of antiretroviral therapies for human immunodeficiency virus (HIV) infection can be assessed by studying the trajectory of the changing viral load with treatment time, but estimation of viral trajectory parameters by using the implicit function form of linear and nonlinear parametric models can be problematic. Using longitudinal viral load data from a clinical study of HIV-infected patients in Taiwan, we described the viral trajectories by applying a nonparametric mixed-effects model. We were then able to compare the efficacies of highly active antiretroviral therapy (HAART) and conventional therapy by using Young and Bowman’s (1995) test.
