Imperfect Knowledge of Pension Plan Type
No full textThis paper investigates the reasons for discrepancies between the pension plan type reported by respondents to the Health and Retirement Study (HRS) and pension plan type obtained from documents produced by their employers, called Summary Plan Descriptions (SPDs). The analysis suggests the discrepancies are sizable and are mainly due to misreports by respondents. Discrepancies between respondent and firm reports of plan type are first documented for different years and from different data sources. Changes over time in respondent and firm reports are analyzed for those who say their plans did not change. Plan type from payroll data produced by Watson Wyatt, a pension consulting company, is examined and compared to respondent reports for employees covered by Watson Wyatt plans. The Watson Wyatt payroll data report plan type without error, and yet we find the patterns of discrepancies between respondent and firm provided data are the same as for the HRS employer and respondent data. We also explore other evidence gathered by the HRS in the course of interviews and various experiments. Our findings that errors are mainly the result of misreporting by respondents, together with findings from experiments, suggest a number of changes in survey design that can help to reduce reporting error. They also suggest that models of retirement and saving behavior should allow for imperfect knowledge by decision makers.

Lower-limb kinematics of single-leg squat performance in young adults
No full textPurpose: To determine the kinematic parameters that characterize good and poor single-leg squat (SLS) performance. Methods: A total of 22 healthy young adults free from musculoskeletal impairment were recruited for testing. For each SLS, both two-dimensional video and three-dimensional motion analysis data were collected. Pelvis, hip, and knee angles were calculated using a reliable and validated lower-limb (LL) biomechanical model. Two-dimensional video clips of SLSs were blindly assessed in random order by eight musculoskeletal physiotherapists using a 10-point ordinal scale. To facilitate between-group comparisons, SLS performances were stratified by tertiles corresponding to poor, intermediate, and good SLS performance. Results: Mean ratings of SLS performance assessed by physiotherapists were 8.3 (SD 0.5), 6.8 (SD 0.7), and 4.0 (SD 0.8) for good, intermediate, and poor squats, respectively. Three-dimensional analysis revealed that people whose SLS performance was assessed as poor exhibited increased hip adduction, reduced knee flexion, and increased medio-lateral displacement of the knee joint centre compared to those whose SLS performance was assessed as good (p=0.05). Conclusions: Overall, poor SLS performance is characterized by inadequate knee flexion and excessive frontal plane motion of the knee and hip. Future investigations of SLS performance should consider standardizing knee flexion angle to illuminate other influential kinematic parameters.No Full Tex
Unified mathematical treatment of complex cascaded bipartite networks: The case of collections of journal papers
No full textIn this study, a mathematical treatment is proposed for analysis of entities and relations among entities in
complex networks consisting of cascaded bipartite networks. This treatment is applied to the case of
collections of journal papers. In this case, entities are distinguishable objects and concepts, such as papers,
references, paper authors, reference authors, paper journals, reference journals, institutions, terms, and term
definitions. Relations are associations between entity-types such as papers and the references they cite, or
paper authors and the papers they write. An entity-relationship model is introduced that explicitly shows
direct links between entity-types and possible useful indirect relations. From this a matrix formulation and
generalized matrix arithmetic are introduced that allow easy expression of relations between entities and
calculation of weights of indirect links and co-occurrence links. Occurrence matrices, equivalence
matrices, membership matrices and co-occurrence matrices are described. A dynamic model of growth
describes recursive relations in occurrence and co-occurrence matrices as papers are added to the paper
collection. Graph theoretic matrices are introduced to allow information flow studies of networks of papers
linked by their citations. Similarity calculations and similarity fusion are explained. Derivation of feature
vectors for pattern recognition techniques is presented. The relation of the proposed mathematical
treatment to seriation, clustering, multidimensional scaling, and visualization techniques is discussed. It is
shown that most existing bibliometric analysis techniques for dealing with collections of journal papers are
easily expressed in terms of the proposed mathematical treatment: co-citation analysis, bibliographic
coupling analysis, author co-citation analysis, journal co-citation analysis, Braam-Moed-vanRaan (BMV)
co-citation/co-word analysis, latent semantic analysis, hubs and authorities, and multidimensional scaling.
This report discusses an extensive software toolkit that was developed for this research for analyzing and
visualizing entities and links in a collection of journal papers. Additionally, an extensive case study is
presented, analyzing and visualizing 60 years of anthrax research through a collection of journal papers.
When dealing with complex networks that consist of cascaded bipartite networks, the treatment presented
here provides a general mathematical framework for all aspects of analysis of static network structure and
network dynamic growth. As such, it provides a basic paradigm for thinking about and modeling such
networks: computing direct and indirect links, expressing and analyzing statistical distributions of network
characteristics, describing network growth, deriving feature vectors, clustering, and visualizing network
structure and growth

No full textWhat does it mean to be an academic? A public intellectual? What is the role of the universities today? Who better to ask than the people who for decades have worked, taught, struggled and lived in these places. Steven Shapin is the Franklin L. Ford Research Professor of the History of Science at Harvard University. He was part of the Science Studies Unit at Edinburgh University in the 1970s and went on to co-author the influential Leviathan and the Air-Pump: Hobbes, Boyle, and the Experimental Life. In this book you can read about his journey through the heydays of Science Studies and his thoughts on the future of universities. In the Questions & Afthoughts series you will meet some of the finest and most distinguished senior professors—you will meet living history. They are interviewed by young graduate students, who are eager to learn from past experiences of trial and error in academia, both professionally and personally.What does it mean to be an academic?

The stability of IQ in people with low intellectual ability: an analysis of the literature
No full textA meta-analysis of the stability of low IQ (IQ 80) was performed on IQ tests that have been
commonly used—tests that were derived by D. Wechsler (1949, 1955, 1974, 1981, 1991, 1997)
and those based on the Binet scales (L. M. Terman, 1960; L. M. Terman & Merrill, 1972). Weighted-
mean stability coefficients of .77 and .78 were found for Verbal IQ (V IQ) and Performance IQ
(P IQ) on the Wechsler tests and .82 for Full-Scale IQ (FS IQ) on both Wechsler and Binet tests,
for a mean test–retest interval of 2.8 years. Although the majority of FS IQs changed by less than
6 points, 14% changed by 10 points or more. The author suggests that the results of IQ assessment
should be treated with more caution than previously thought
Phasing Into Retirement
No full textEmployers have been launching phased retirement programs to help workers navigate the transition from work to retirement more effectively. This paper examines the experience of the phased retirement system for tenured faculty in the University of North Carolina system. After phased retirement was introduced, there was a sizable increase in the overall separation rate in the system. A multinomial logit model of the retirement decision as a function of pension incentives, employee performance, demographics, and campus characteristics is developed. The key empirical result is that the odds of entering phased retirement are strongly and inversely related to employee performance, as measured by recent pay increases.
