This paper presents individual country notes for the paper "Trends in Rentier Shares in OECD Countries, 1966-2000 (Power, Epstein and Abrena, 2003). Meant for the specialist, these notes explain data sources and methods for each country in our sample.
Brillouin Cooling
We analyze how to exploit Brillouin scattering for the purpose of cooling
opto-mechanical devices and present a quantum-mechanical theory for Brillouin
cooling. Our analysis shows that significant cooling ratios can be obtained
with standard experimental parameters. A further improvement of cooling
efficiency is possible by increasing the dissipation of the optical anti-Stokes
resonance.Comment: 4 pages 3 figure
Examining the benefit of graduated compression stockings in the prevention of hospital-associated venous thromboembolism in low-risk surgical patients: a multicentre cluster randomised controlled trial (PETS trial)
Introduction Hospital-acquired
thrombosis (HAT) is
defined as any venous thromboembolism (VTE)-related
event during a hospital admission or occurring up to 90
days post discharge, and is associated with significant
morbidity, mortality and healthcare-associated
costs.
Although surgery is an established risk factor for VTE,
operations with a short hospital stay (<48 hours) and
that permit early ambulation are associated with a low
risk of VTE. Many patients undergoing short-stay
surgical
procedures and who are at low risk of VTE are treated
with graduated compression stockings (GCS). However,
evidence for the use of GCS in VTE prevention for this
cohort is poor.
Methods and analysis A multicentre, cluster randomised
controlled trial which aims to determine whether GCS are
superior in comparison to no GCS in the prevention of VTE for
surgical patients undergoing short-stay
procedures assessed
to be at low risk of VTE. A total of 50 sites (21 472 participants)
will be randomised to either intervention (GCS) or control
(no GCS). Adult participants (18–59 years) who undergo
short-stay
surgical procedures and are assessed as low risk
of VTE will be included in the study. Participants will provide
consent to be contacted for follow-up
at 7-days
and 90-days
postsurgical procedure. The primary outcome is the rate of
symptomatic VTE, that is, deep vein thrombosis or pulmonary
embolism during admission or within 90 days. Secondary
outcomes include healthcare costs and changes in quality of
life. The main analysis will be according to the intention-to-
treat
principle and will compare the rates of VTE at 90 days,
measured at an individual level, using hierarchical (multilevel)
logistic regression.National Institute for Health Research (NIHR) NIHR13377

Trends In The Rentier Income Share In OECD Countries, 1960-2000
This paper presents the first set of estimates of the rentier share of income for twenty-nine OECD countries. We define rentier share to mean the income accruing to financial institutions and the holders of financial assets. The years of coverage vary by country, but span the period 1960-2000. The paper presents the estimates, describes in detail the methods used to construct the series, and presents comprehensive information on our data sources. In addition, we compare the trends in rentier shares with the share of income going to non-financial corporations. Overall we find that the rentier share of income rose in most countries between the 1960\u27s and 1970\u27s on the one hand, and the 1980\u27s and 1990\u27s, on the other. At the same time, movements in rentier income over this period vary from country to country, and are quite variable over time. We also present estimates for rentier shares including capital gains for a subset of countries in the 1980\u27s and 1990\u27s. Including capital gains substantially alters the trend of rentier shares in the 1990\u27s, in most cases, causing them to increase
Polymerizing the fibre between bacteria and host cells: the biogenesis of functional amyloid fibres
Amyloid fibres are proteinaceous aggregates associated with several human diseases, including Alzheimer's, Huntington's and Creutzfeldt Jakob's. Disease-associated amyloid formation is the result of proteins that misfold and aggregate into β sheet-rich fibre polymers. Cellular toxicity is readily associated with amyloidogenesis, although the molecular mechanism of toxicity remains unknown. Recently, a new class of ‘functional’ amyloid fibres was discovered that demonstrates that amyloids can be utilized as a productive part of cellular biology. These functional amyloids will provide unique insights into how amyloid formation can be controlled and made less cytotoxic. Bacteria produce some of the best-characterized functional amyloids, including a surface amyloid fibre called curli. Assembled by enteric bacteria, curli fibres mediate attachment to surfaces and host tissues. Some bacterial amyloids, like harpins and microcinE492, have exploited amyloid toxicity in a directed and functional manner. Here, we review and discuss the functional amyloids assembled by bacteria. Special emphasis will be paid to the biology of functional amyloid synthesis and the connections between bacterial physiology and pathology.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/75549/1/j.1462-5822.2008.01148.x.pd
Characteristics of emotional disturbance of female and male students in elementary, middle, and high school
Provide data on the five characteristics of emotional disturbance (ED). For 503 students with ED and 2016 without disabilities, teachers rated the characteristics (Inability to Learn; Relationship Problems; Inappropriate Behavior; Unhappiness or Depression; Physical Symptoms or Fears), plus Socially Maladjusted. We applied a 2 (ED, without disabilities) × 2 (female, male) × 3 (elementary, middle, high school) covariance analysis, with follow‐up comparisons. Students with ED showed greater problems than students without disabilities on all five characteristics, and Socially Maladjusted. On Inability to Learn, among students with ED genders did not differ at elementary but males had greater problems at middle school. On Inappropriate Behavior and Physical Symptoms or Fears, students with ED varied across school levels but students without disabilities did not. All five characteristics discriminated students with ED from those without disabilities. Differences between genders and school levels varied across characteristics
Factor Analysis of the Preschool Behavioral and Emotional Rating Scale for Children in Head Start Programs
Strength-based assessment of behaviors in preschool children provides evidence of emotional and behavioral skills in children, rather than focusing primarily on weaknesses identified by deficit-based assessments. The Preschool Behavioral and Emotional Rating Scales (PreBERS) is a normative assessment of emotional and behavioral strengths in preschool children. The PreBERS has well-established reliability and validity for typically developing children as well as children with identified special education needs, but this has not yet been established for children in Head Start programs, who tend to be at high risk for development of emotional and behavioral concerns. This study explores the factorial validity of the PreBERS scores for a large sample of children participating in Head Start programs around the United States. Results not only confirm the fit of the four-factor model of the PreBERS for this population, but also demonstrate the application of a bifactor model to the structure of the PreBERS which, in turn, allows for the computation of model-based reliability estimates for the four subscales (Emotional Regulation, School Readiness, Social Confidence, Family Involvement) and overall strength index score. The implications suggest that the PreBERS items are reliable scores that can be used to identify behavioral strengths in preschool children in Head Start, and support planning of interventions to selectively address component skills to promote child social and academic success
On the Effective Communication of the Results of Empirical Studies, Part II
In an important and certainly timely article published in the N.Y. U. Law Review, Nancy C. Staudt demonstrates that, in taxpayer standing cases, judges are motivated by politics but can be constrained when the law is clear and oversight exists. As part of that demonstration, Professor Staudt offers an empirical analysis of the decision to grant standing to federal taxpayers-the results of which we reproduce in Table 1.2
What are we to make of this rather ominous-looking table? Professor Staudt suggests two key takeaways. First, the analysis, she reports, shows that doctrine helps explain standing decisions even when political factors are taken into account. Both legal variables ( Spending and Spending and Establishment Clause ) are statistically significant, controlling for all other factors listed in the table. Second, she finds an important role for the politics of the plaintiff: Judges are more likely to grant standing to a liberal plaintiff, regardless of their own political leanings.
No doubt, the data support Professor Staudt\u27s claim about the importance of politics. The asterisk on the Plaintiff Politics variable, for example, tells us that a statistically significant relationship exists between a plaintiffs political ideology and the decision to grant standing
