Why Do Pensions Reduce Mobility?
Previous studies have found that workers who are covered by pensions are much less likely than other workers to leave their jobs, but the evidence on how specific pension characteristics affect turnover is inconclusive. This paper examines how mobility is affected by vesting standards, the compensation level, and the capital loss of pension wealth for job changers. In two different data sets, we find that the capital loss is strongly associated with lower turnover rates, whereas vesting and the compensation level have relatively little impact. Large capital losses are mainly associated with lower layoff rates rather than lower quit rates.
Pension Wealth, Age-Wealth Profiles and the Distribution of Net Worth
This study estimates the magnitude of pension wealth and compares pension wealth to net worth for households in the 1983 Survey of Consumer Finance (SCF). The SCF is the first data set to provide detailed information on both household finances and pension characteristics. The pension information is provided by the employer, so that it is much more detailed and likely to be more accurate than the pension data used in previous studies. Pension wealth was estimated under two sets of assumptions. Under the projected earnings approach, mean pension wealth is 47,541, which represents 26 percent of mean net worth for households with pensions. Both estimates are much larger than those obtained in earlier studies. The study also examines how estimates of inequality in the wealth distribution change when pension wealth is added to household balance sheets. Using a variety of methods and assumptions, the distribution becomes more equal when the definition of wealth is expanded to include pension assets.
Pensions, Bonding, and Lifetime Jobs
A well-known, if underappreciated, finding in the mobility literature is that turnover is much lower in jobs covered by pensions than in other jobs. This could result from capital losses for job changes created by most benefit formulas, the tendency of turnover-prone individuals to avoid jobs covered by pensions, or higher overall compensation levels in such jobs. A switching bivariate probit model of pension coverage and turnover is developed to estimate the effect of each of these factors. The results show that capital losses are the main factor responsible for lower turnover in jobs covered by pensions, but self-selection and compensation levels also play an important role. This is the first direct evidence that bonding is important for understanding long-term employment relationships.
Sex Differences, Financial Education, and Retirement Goals
This chapter examines the impact of participation in financial education seminars on the desired retirement age of individuals and on their expected levels of retirement income. Individuals were found to change their retirement goals after attendance in such a seminar. In addition, participants also reported that they planned to change their retirement saving behavior based on knowledge gained at the seminar. Women were much more likely to alter their retirement goals and saving behavior. Using information on seminars conducted by TIAA-CREF, and survey data on the participants, the authors estimate the determinants of changes in retirement goals and saving behavior
Toward Understanding the Role of Amot80 Lipid Binding in Cellular Proliferation and Migration
poster abstractsAmots are adaptor proteins which coordinate signaling that controls cellular differentiation and proliferation, and their Amot coiled-coil homology (ACCH) domain is able to bind lipids with specificity which leads to membrane deformation and targets transcription factors to the nucleus. Understanding the biophysical mechanisms involved in lipid binding may provide pathways to modulate protein sorting and downstream signaling events inducing cellular differentiation, cancer cell proliferation, and migration. At this time, all work reported on signaling based on Amot expression is unable to distinguish between the role of the Amot80 and the 130 family members as they share a common ACCH domain. The goal of this project is to specifically relate the Amot80 ACCH lipid binding with function related to cancer phenotypes Mutations were carried forward based on lipid sedimentation, FRET, and SAXS assays against the ACCH domain of the protein. Site-directed mutagenesis was then employed to probe the specific contributions of 7 selected lysines and arginines toward lipid head-group binding in the full length protein. The polarity/scaffolding signaling effect of mutations in the Amot80 will be monitored by matrigel, accumulation/cell counting, and titrated thymidine incorporation assays. Cell morphology will be imaged by confocal imaging, and cellular migration will be recorded by video. The effects on YAP1/2 and MAPK activation will be assessed by immunoblot analysis. The changes will then be correlated in extracellular scaffolding and migration with immunoblots and cellular staining. Likewise, effects on proliferation will be monitored by MTT assays. The hypothesis of this aim is that modulation of Amot’s ability to bind selective lipids will interrupt the signaling pathways leading to cellular migration, differentiation, and proliferation.

Introduction The prevalence of obesity-related disorders has been steadily increasing over the past couple of decades. Diseases that were once only detected in adults are now prevalent in children, such as hyperlipidemia. The adipose tissue-derived hormonal factor C1q TNF Related Protein 3 (CTRP3) has been linked to triglyceride regulation especially in animal models. However, the relationship between circulating CTRP3 levels and obesity-related disorders in human subjects is controversial. CTRP3 can circulate in different oligomeric complexes: trimeric (kDa), middle molecular weight (100–300 kDa), and high molecular weight (HMW) oligomeric complexes (\u3e300 kDa). Previous work has identified that it is not the total amount of CTRP3 present in the serum, but the specific circulating oligomeric complexes that appear to be indicative of the relationship between CTRP3 and serum lipids levels. However, this work has not been examined in children. Therefore, the purpose of this study was to compare the levels of different oligomeric complexes of CTRP3 and circulating lipid levels among young children (aged 7–10 years). Methods Morphometric data and serum samples were collected and analyzed from a cross-sectional population of 62 children of self-identified Hispanic origin from a community health center, between 2015 and 2016. Serum analysis included adiponectin, insulin, leptin, ghrelin, glucagon, C-reactive peptide, triglyceride, cholesterol, IL-6, TNF, and CTRP3. Correlation analyses were conducted to explore the relationships between CTRP3 and other biomarkers. Results Total CTRP3 concentrations were significantly positively correlated with total cholesterol and HDL cholesterol. Whereas, HMW CTRP3 was not significantly associated with any variable measured. Conversely, the middle molecular weight (MMW) CTRP3 was negatively correlated with triglycerides levels, and very low-density lipoprotein (VLDL), insulin, and body mass index (BMI). The negative correlations between MMW CTRP3 and triglycerides and VLDLs were particularly strong (r2 = -0.826 and -0.827, respectively). Conclusion Overall, these data indicate that the circulating oligomeric state of CTRP3 and not just total CTRP3 level is important for understanding the association between CTRP3 and metabolic diseases. Further, this work indicates that MMW CTRP3 plays an important role in triglyceride and VLDL regulation which requires further study
Penicillin Use in Meningococcal Disease Management: Active Bacterial Core Surveillance Sites, 2009.
In 2009, in the Active Bacterial Core surveillance sites, penicillin was not commonly used to treat meningococcal disease. This is likely because of inconsistent availability of antimicrobial susceptibility testing and ease of use of third-generation cephalosporins. Consideration of current practices may inform future meningococcal disease management guidelines
Hepatitis B assays in serum, plasma and whole blood on filter paper
BACKGROUND: Screening and determining the immune status of individuals for hepatitis B is usually done by detecting hepatitis B surface antigen (HBsAg) and hepatitis B surface antigen-specific antibodies (HBsAb). In some countries with the highest viral burden, performing these assays is currently impractical. This paper explores the use of filter paper as a blood specimen transport medium. METHODS: Samples, chosen from routine clinical laboratory pool, were applied and dried onto filter paper. Eluates, from the paper samples, were analyzed as routine clinical specimens on ADVIA Centaur 5634® immunoassay analyzers using the standard HBsAg and HBsAb kits. Dried blood samples were subjected to a range of environmental conditions in order to assess stability. RESULTS: After drying and elution the assays showed linearity and precision comparable to clinical assays performed on fresh serum. Elutions at various times during a 149 day incubation period showed very little variability in the Index numbers. All analytes were temperature stable except for a decrease in the HBsAg signal at 42°C. CONCLUSIONS: Filter paper is an acceptable storage and transport medium for serum to be used in the detection of hepatitis B markers if atmospheric variability can be controlled. HBsAg, HBsAb and HBcAb are all stable for at least five months under storage conditions below room temperature. Drying specimens, particularly serum, on filter paper at remote locations, offers a reasonable solution to the problem of hepatitis surveillance in underdeveloped regions, although some attempt at temperature control might be desirable
The Pension Cost of Changing Jobs
Workers covered by defined benefit pension plans receive lower benefits at retirement if they leave their current job before reaching retirement age. This study estimates the magnitude of this pension loss for workers in the May 1983 supplement of the Current Population Survey, using pension formula estimates from the 1983 Employee Benefit Survey. The pension loss is generally greatest between the ages of 35 and 54 and represents roughly half of a year's earnings for that age group. The loss tends to be quite high in the declining mining and manufacturing sectors. This probably resulted in lower voluntary attrition at a time of massive layoffs and plant closings.
