The potential for work enforcement: A study of WIN

Given the impediments around them, can welfare recipients be required to work? Most analysts have answered no. They say the recipients are usually kept from employment by socioeconomic barriers, such as insufficient jobs, and the disincentives to work inherent in welfare. Studies of recent AFDC work programs make them look promising but do not directly address the potential for work enforcement. This article, a cross-sectional study of state WIN programs in 1979, suggests that work requirements could raise work levels substantially despite the impediments. But requirements probably do not improve the quality of jobs recipients are able to get. Therefore, enforcement serves the goal of integration, but to achieve greater economic equality will require additional reforms.     

Laws, Models, and Real People: Choice of Chapter in Personal Bankruptcy

It has been a central assumption in bankruptcy policy debates that financially troubled persons faced with bankruptcy will respond to economic incentives and disincentives. Two provisions of the Bankruptcy Code (Chapters 7 and 13) are most commonly used by individual debtors. Under Chapter 7 debtors agree to give up all their property (n excess of state-determined exemptions) to a trustee for sale and distribution to creditors. Under Chapter 13 debtors keep all their property but agree to pay all or part of their debts over three to five years. This empirical study of fifteen hundred consumers in three states explores whether economic incentives and disincentives are in fact the chief factors influencing choice of chapter. The analysis demonstrates that while economic factors play a part, noneconomic factors are also significant, among them intra- and interstate migration, marital status, self-employment, state of residence, and local legal culture. We conclude that to explore fully how individual decisions are made, the simplistic economic model must be replaced by a more sophisticated model that accounts for both economic and noneconomic factors.     

Accuracy of cause of death determination without forensic autopsy examination

Medical examiners and coroners commonly determine cause and manner of death without an autopsy examination. Some death certificates generated in this way may not state the correct cause and manner of death. From the case files of the Department of Forensic Medicine in Sydney, Australia, the authors retrospectively reviewed investigative information of all cases in a 6-month period that were initially considered natural deaths (429). The authors, blinded to autopsy results, accepted 261 cases as appropriate for certification without autopsy and assigned a cause of death to each. Per standard local practice, all cases had been autopsied. The actual causes of death as determined by autopsy were then revealed and compared with the presumed causes of death. Most presumed and actual causes of death were cardiovascular (94% and 80%, respectively). The majority of presumed causes of death were listed as ASCVD as the cases lacked features of a more specific cardiovascular process. A large majority of cases had a presumed cause of death of ischemic heart disease based on individual case details. The actual causes of death demonstrated a large breadth of cardiovascular and noncardiovascular disease processes, even though ischemic heart disease accounted for 62% of deaths. The presumed cause of death was completely wrong in 28% of cases. A nonnatural manner of death was present in 3% of cases. This study demonstrates that experienced forensic pathologists may generate erroneous death certificates for cases that are not autopsied.     

Valuing Policy Alternatives: A Generalization

Those interested in political phenomena such as voting havefound random utility models, originally developed for decisionssuch as transportation choice, especially attractive, as theunderlying model can yield a statistical model with a few simple,realistic assumptions. Unfortunately, such models have provendifficult to apply to situations with more than two votes andthree alternatives or an unknown cutpoint. Additionally, aswe show, standard applications of such models to voting, whileproducing consistent parameter estimates, yield standard errorsthat are too small and, due to a failure to employ all relevanttheoretical information, biased ideal point estimates. We specifya general model applicable to any number of votes and alternatives,with correct standard errors and unbiased ideal point estimates.We apply this model to a number of cases studied by previousscholars involving legislative voting over the minimum wage:(1) when there are two votes and two known cutpoints (K. Krehbieland D. Rivers, American Journal of Political Science, 1988,32, 1151–1174); (2) when there are three votes and threeknown cutpoints (J. Wilkerson, American Journal of PoliticalScience, 1991, 35, 613–623); and (3) when there are threevotes but where one cutpoint is unknown given a lack of knowledgeabout the impact of a policy (J. Wilkerson, American Journalof Political Science, 1991, 35, 613–623) or the possibilityof sophisticated voting (C. Volden, Journal of Politics, 1998,60, 149–173). We show that in various contexts our analysisimproves on existing methods, yielding consistent and efficientideal point estimates and a better-fitting model with improvedpredictive accuracy.     

An ELISA method for the identification of salivary amylase

An ELISA method for the detection of salivary amylase in dried stains using a monoclonal anti-human salivary amylase antibody was developed. Studies demonstrated the assay to be sensitive down to 0.0002 Sigma units and showed a linear response between absorbance and salivary amylase activity between 0.002 and 0.2 units. The assay showed no cross reactivity with either commercially purchased human pancreatic or bacterial amylase. Sample studies utilizing swabs from several human body fluids showed that 100% of all saliva containing swabs (sixteen of sixteen) and 13% of non-saliva human body fluid swabs (eight of sixty-three) showed a net absorbance with the method. Of these eight non-saliva swabs yielding a net absorbance, none exceeded a salivary amylase activity of 0.003 units. In contrast, only three of the sixteen saliva-containing swabs (swabs produced from saliva diluted 1:5, 1:6, and 1:10, respectively) showed an activity below 0.2 units. Of these swabs, the 1:100 dilution showed the lowest activity (0.048). This value is still more than ten times that of the non-saliva containing swab with the highest activity.
