Appraisal of root leakage as a method for estimation of root viability

Abstract: We review the applications of REL test as a technique for detecting injury and thereby forecasting survivability of transplanted seedlings. The objectives of the present review are to present the fundamentals of this method, assess the relevant literature, present evidence of seasonal variations of REL, describe how REL responds to different stress conditions, suggest priorities for future research as well as practical recommendations for REL testing, and assess leakage of organic compounds as an indicator of root damage. Seasonal changes in REL may be connected with root freezing tolerance that varies among plants of different seed sources and species and thus does not always indicate health state of seedlings. REL technique can be used for assessing frost hardiness of roots under certain conditions (e.g. roots should be sampled into the test tubes prior to the freezing test). It can be used for studying heat stress with certain prerequisites (e.g. series of high temperatures or different exposu...

OR/MS: Dead or Dying? RX for Survival

Abstract: An essay about the status of OR/MS in business and academia. Considerations about decreased visibility, disappearance of well-structured problems, and third-generation faculty concerned more with the publishability of results than resolving practical problems are expressed. Some practical steps towards improvement are suggested.

Marital Disruption and Health Insurance

Abstract: Despite the high levels of marital disruption in the United States and the fact that a significant portion of health insurance coverage for those less than age 65 is based on family membership, surprisingly little research is available on the consequences of marital disruption for the health insurance coverage of men, women, and children. We address this shortfall by examining patterns of coverage surrounding marital disruption for men, women, and children, further subset by educational level. Using the 1996, 2001, and 2004 panels of the Survey of Income and Program Participation (SIPP), we find large differences in health insurance coverage across marital status groups in the cross-section. In longitudinal analyses that focus on within-person change, we find small overall coverage changes but large changes in type of coverage following marital disruption. Both men and women show increases in private coverage in their own names, but offsetting decreases in dependent coverage tend to be larger. One surprising result is that dependent coverage for children also declines after marital dissolution, even though children are still likely to be eligible for that coverage. Children and (to a lesser extent) women show increases in public coverage around the time of divorce or separation. We also find that these patterns differ by education. The most vulnerable group appears to be lower-educated women with children because the increases in private, own-name, and public insurance are not large enough to offset the large decrease in dependent coverage. As the United States implements federal health reform, it is critical that we understand the ways in which life course events—specifically, marital disruption—shape the dynamic patterns of coverage.

Medicaid managed care payment rates in 1998

Abstract: This paper reports on a new survey of state Medicaid managed care payment rates. We collected rate data for Medicaid's Aid to Families with Dependent Children (AFDC)/Temporary Assistance for Needy Families (TANF) and poverty-related populations and made adjustments to make the data comparable across states. The results show a slightly more than twofold variation in capitation rates among states, caused primarily by fee-for-service spending levels and demographics. There is a very low correlation between the variation in Medicaid capitation rates among states and the variations in Medicare's adjusted average per capita cost. The data are not sufficient to answer questions about the adequacy of rates but should help to further policy discussions and research.

Successful Aging Through Successful Accommodation With Assistive Devices

Abstract: Objectives To provide a profile of older adults who successfully accommodate declines in capacity by using assistive devices. Method Using the National Health and Aging Trends Study, we provide national estimates of prevalent, incident, and persistent successful accommodation of mobility and self-care activity limitations. For incident and persistent accommodation groups, we describe their subjective wellbeing and participation restrictions, health and functioning, demographic and socioeconomic characteristics, and acquisition of assistive devices and environmental features. We estimate regression models predicting incident and persistent successful accommodation and the extent of wellbeing and participation restrictions for incident and persistent groups (vs. those who are fully able). Results Nearly one-quarter of older adults have put in place accommodations that allow them to carry out daily activities with no assistance or difficulty. In adjusted models, incident and persistent successful accommodation is more common for those ages 80-89, those with more children, and those living in homes with environmental features already installed; wellbeing levels for these groups are similar and participation restrictions only slightly below those who are fully able. Discussion A focus on facilitating successful accommodation among those who experience declines in capacity may be an effective means of promoting participation and wellbeing in later life.
