Chemical Contamination of Soft Drinks in Sealed Plastic Bottles by Environmental Stress Cracking

Abstract:  A contamination of soft drinks in sealed bottles by organic solvents is reported: closed bottles full of soft drinks were accidentally placed on a cardboard soaked with thinner and the organic fluid subsequently fissured the bottom of the bottles and penetrated into the soft drinks without any apparent leakage of the soft drinks. Experiments were carried out to simulate the process: the penetration of different organic solvents into soft drinks through the bottom of closed bottles was tested. The penetration occurred only when the closed bottles contained carbonated soft drinks (CSD), indicating that inner pressure is a necessary condition for the fissuring of the bottles. This paper discusses environmental stress cracking of polyethylene terephthalate (PET) bottles by organic solvents and migration of chemicals to CSD. Experiments were conducted to determine the conditions in which PET can be permeable to poisoning organic products.     

Disability beneficiaries who work and their experience under program work incentives.

This research examines the return to work by Disability Insurance beneficiaries who were first entitled to benefits in 1980-81 and who were originally selected to be interviewed in the New Beneficiary Survey. To facilitate an examination of actual labor-force participation by beneficiaries, information on work and participation in program work incentives was collected from their claims folders. The analysis shows that approximately 10 percent of disability beneficiaries work during their initial period of benefit entitlement. About 80 percent are granted a trial work period, and over 70 percent of those granted trial work successfully complete it. More than half of them, however, were not successful in leaving the rolls through their work effort. In fact, benefit terminations due to work occurred for fewer than 3 percent of all beneficiaries in the cohort; approximately one-third of them had returned to the rolls by the end of the period under study. Beneficiaries most likely to make a work attempt were young and had a high level of education. Those with a high Social Security benefit amount were less likely to make a work attempt.     

LESSENING THE STING OF ASFA: THE REHABILITATION‐RELAPSE DILEMMA BROUGHT ABOUT BY DRUG ADDICTION AND TERMINATION OF PARENTAL RIGHTS

Congress passed the Adoption and Safe Families Act of 1997 (ASFA) as a response to children waiting in foster homes for years without permanent placement. In addressing the problem of permanency, however, Congress set a strict limit on how long a child could be in foster care (15 out of the most recent 22 months) before a state must either commence a proceeding to terminate parental rights or else lose valuable federal funding. Due to health care funding schemes and quality of treatment, this requirement, in particular, negatively impacts parents currently in drug rehabilitation whose parental rights may be permanently terminated before a realistic chance to recover is permitted. Although ASFA requires that states make “reasonable efforts” to keep families united, it does not define “reasonable efforts,” leaving parental rights and family unity subject to a chaotic interpretation of this requirement from state to state. “Reasonable efforts” should be interpreted to take into account current drug addiction and recovery research and drug court programs should be used to facilitate this goal. Research has shown that focusing on adequate treatment saves states money and improves the lives of children and their families, reducing the need for reliance on termination of parental rights.     

Does retirement education teach people to save pension distributions?

As defined contribution pension plans have become increasingly common over the past two decades, so have lump sum distributions from those plans. Employees who elect such a distribution take the balance of their pension account with them when they leave a job. They can then choose to maintain the funds in accounts designated for retirement, invest them in other saving vehicles, or spend them. If spent pension distributions are not replaced by other savings, however, the future elderly are unlikely to be able to maintain a desirable standard of living. With employee-funded pensions expected to play an increasingly important role in financing Americans' retirement, saving these funds in essential. This article is the first to examine the relationship between retirement education--specifically, meetings sponsored by employers or by public and private institutions--and the saving of lump sum distributions. Two definitions of saving are used: one that includes reinvestment only in tax-deferred saving vehicles, and a broader one that includes tax-deferred vehicles, general saving vehicles (stocks, bonds, savings accounts, and so on), and paying off debt. The analysis also evaluates the effects of retirement education on specific groups identified in previous research as being less likely to keep their pension distributions in tax-deferred accounts: namely, women, younger persons, and persons with less than a college education. The same groups tend to be less financially secure in retirement, making the effects of retirement education on them particularly relevant. With an econometric model using ordinary least squares and data from the 1992 Health and Retirement Study, the analysis finds that retirement education does not affect the overall likelihood that employees will save their distributions, whether in tax-deferred or non-tax-deferred vehicles. The picture is more complicated for subgroups of employees. Attending a retirement meeting is associated with an increased likelihood of saving among persons age 40 and under but a decreased probability of saving among college graduates and women. No effect was found for men, individuals over age 40, or persons who did not graduate from college. The finding that retirement education increases the likelihood of younger persons' saving a distribution is reassuring, for these workers are America's future retirees. However, the finding that attending a meeting does not increase saving among some of the most financially vulnerable groups is a matter of concern to policymakers. Further study of the long-term effects of spending pension distributions is needed.     

Current Issues

In June and early July 2000, the European football championships were held in the Netherlands and Belgium. It was a large-scale event for both countries. The Minister of the Interior and Kingdom Relations assigned the Crisis Research Center (COT Leiden University) to study the organisation and implementation of the event in the Netherlands and to draw lessons for future large-scale events. The researchers set out the general conclusions and resultant information in this article.
