An updated global compilation of 377 new and previously published ages indicates that granitic pegmatites range in age from Mesoarchean to Neogene and have a semi-periodic age distribution. Undivided granitic pegmatites show twelve age maxima: 2913, 2687, 2501, 1853, 1379, 1174, 988, 525, 483, 391, 319, and 72 Ma. These peaks correspond broadly with various proxy records of supercontinent assembly, including the age distributions of granites, detrital zircon grains, and passive margins. Lithium-cesium-tantalum (LCT) pegmatites have a similar age distribution to the undivided granitic pegmatites, with maxima at 2638, 1800, 962, 529, 485, 371, 309, and 274 Ma. Lithium and Ta resources in LCT pegmatites are concentrated in the Archean and Phanerozoic. While there are some Li resources from the Proterozoic, the dominantly bimodal distribution of resources is particularly evident for Ta. This distribution is similar to that of orogenic gold deposits, and has been interpreted to reflect the ...
While several plots of the aggregate age distribution suggest that firm age is exponentially distributed, we find some departures from the exponential benchmark. At the lower tail, we find that very young establishments are more numerous than expected, but they face high exit hazards. At the upper tail, the oldest firms are older than the exponential would have predicted. Furthermore, the age distribution of disaggregated industries (such as the international airline industry) is less regular and can display multimodality. Although we focused on departures from the exponential, we found that the exponential was a useful reference point and endorse it as an appropriate benchmark for future work on industrial structure. ...

Downloadable! Psychological well-being (WB) includes a person?s overall appraisal of his or her life (Global WB) and affective state (Hedonic WB), and it is considered a key aspect of the health of individuals and groups. Several cross-sectional studies have documented a relation between Global WB and age. Little is known, however, about the age distribution of Hedonic WB. It may yield a different view of aging because it is less influenced by the cognitive reconstruction inherent in Global WB measures and because it includes both positive and negative components of WB. In this study we report on both Global and Hedonic WB assessed in a 2008 telephone survey of 340,847 people in the United States. Consistent with prior studies, Global WB and positive Hedonic WB generally had U-shaped age profiles showing increasedWB after the age of 50 years. However, negative Hedonic WB variables showed distinctly different and stronger patterns: Stress and Anger steeply declined from the early 20s, Worry was elevated

Age-standardized rates may be used to compare different geographic areas or time frames to adjust for any differences in the age structure of the populations that could cause a difference in rates.. It reflects the number of events (e.g., deaths, hospitalizations) that would occur for a given population if that population had the same age distribution as the 1991 Canadian population.. Age-standardized rates have been used to make more valid comparisons than comparing crude rates. Standardization requires adjusting for the effects of varying age structures of different populations and over different periods of time. The importance of age-standardization can be illustrated by using Population X, which has a higher proportion of elderly persons than Population Y. The unadjusted or crude mortality rate for Population X would be significantly higher than Population Y solely because it has a higher proportion of elderly persons and the elderly have a much higher death rate than younger people. This ...
Age-Adjusted Death Rate: When comparing rates over time or across different populations, crude rates (the number of deaths per 100,000 persons) can be misleading, because differences in the age distributions of the various populations are not considered. Since death is age-dependent, the comparison of crude rates of death can be especially deceptive.. Age-adjusted rates take into account the diverse age distributions of the populations. Valid comparisons between age-adjusted rates can be made, provided the same standard population and age groups have been used in the calculation of the rates. The direct method of adjustment was used to produce the age-adjusted rates for this report. In this method, the population is first divided into reasonable homogeneous age ranges, and the age-specific rate is calculated for each age range. Then, each age-specific rate is weighted by multiplying it by the proportion of the standard population in the respective age group. The age-adjusted rate is the sum of ...

From 1980 to 2010, the crude incidence of diagnosed diabetes increased 161% from 3.3 to 8.6 per 1,000 population. Similarly, the age-adjusted incidence increased 140% from 3.5 to 8.4 per 1,000 population, suggesting that the majority of the change was not due to the aging of the population. However, from 1980 to 2010, incidence did not increase at a constant rate. Both crude and age-adjusted incidence remained unchanged in the 1980s, and then increased in the 1990s through 2010. From 2008 through 2010, both crude and age-adjusted incidence has shown little change.

I produced a methodology capable of aging the species Rana luteiventris by using a process called skeletochronology. My objective was to find out if the age of the individual could be assessed by counting the number of lines of arrested growth (LAGs) from cross-sections of the third digit of the right hind foot. After this process was refined for this particular species, seventy-four individuals were sampled in order to construct a static age distribution of a population of frogs. Samples were collected from May-August 1998 at a small pond in the Lewis and Clark County, Chessman Marshland, 10 km west of Clancy, Montana. Few individuals were found to be five years of age. The majority of the population was dispersed somewhat evenly between metamorphs, 1, 3, and 4-year-old frogs. As expected, no frogs beyond five years of age were observed. There was a notable lack of 2-year-old frogs. However, I was unable to account for the low number of 2-year-old frogs in the population.
Downloadable! This paper proposes the use of optimal grouping methods for determining the various age groups within a population. The cutoff ages for these groups, such as the age from which an individual is considered to be an older person, are then endogenous variables that depend on the entire population age distribution at any given moment. This method is first applied to the age distribution of the United States and subsequently to a group of 12 industrialized countries. The cutoff ages as well as the main indicators of aging are calculated.

A comparison between mean age theory and conventional residence time distributions over a range of quantified mixing levels was conducted using computational fluid dynamics (CFD). The system was a stirred tubular reactor. The model was validated by comparing computationally derived RTD curves with experimentally obtained RTD curves, with quantified differences less than 3%. Mixing was quantified using the Tanks-in-Series model. Mixing levels were set by varying flow rate and impeller rpm. Mean age distributions at the outlet, where experimental RTDs were measured, were very narrow for all levels of mixing studied. RTDs showed expected characteristics; a wider distribution and long decay for high mixing cases and a narrow distribution centered around the mean time for cases approaching plug flow. Mean age distributions remained substantially narrower than RTDs. RTDs and mean age distributions were measured at several locations along the length of the reactor to determine changes in characteristics of

The current EU LULUCF regulation calls for member state-specific Forest Reference Levels (FRLs) for benchmark in the accounting of greenhouse gas emissions and removals of managed forest land during the compliance period (2021-2030). According to the technical guidance on developing and reporting the FRLs, it could be actualized by projecting a ratio of harvested to total available biomass. We tested how the initial age distribution may affect the aforementioned ratio by simulating the continuation of forest management based on several descriptive shapes of forest age class distribution. Our simulations suggest that when the FRLs are prepared by employing the harvest ratio and forest management is assumed strictly age dynamics driven, the shape of the initial forest age class distribution gives rise to computational sinks or sources of carbon in managed forest land. Harvests projected according to the ratio corresponded those resulting from the age dynamics only in the case of uniform age distribution.
Data analysis. The average annual incidence of cancer in Gipuzkoa for the period 1998-2002 is presented for all sites together, and also for specific sites, and expressed in rates per 100,000 persons at risk per year. Crude, agespecific and age-standardized incidence rates were calculated by gender, using the direct method and adjusted with European and World population data3. Furthermore, cumulative incidence rates were calculated for each site and gender, from birth to 65 and 75 years of age.. The cancer incidence trend for the period 1986-2002 was studied for all tumours and the most frequent sites. The general trend was quantified by applying the Poisson regression12, after adjusting for age, with separate models for men and women. In this model, a linear trend was assumed for the logarithm of the rates. Goodness of fit was assessed by devianceand its degrees of freedom. The significance level was set at 0.05. In the case of prostate cancer, the Poisson model did not fit correlated as a ...
Detrital zircon age distributions provide robust insights into past sedimentary systems, but these age distributions are often complex and multi-peaked, with sample sizes too small to confidently resolve population distributions. This limited sampling hinders existing quantitative methods for comparing detrital zircon age distributions, which show systematic dependence on the sizes of compared samples. The proliferation of detrital zircon studies motivates the development of more robust quantitative methods. We present the first attempt, to our knowledge, to infer probability model ensembles (PMEs) for samples of detrital zircon ages using a Bayesian method. Our method infers the parent population age distribution from which a sample is drawn, using a Monte Carlo approach to aggregate a representative set of probability models that is consistent with the constraints that the sample data provide. Using the PMEs inferred from sample data, we develop a new estimate of correspondence between ...
The data reported in this table are derived from the HIPE (Hospital In-Patient Enquiry) data set, which records data on discharges from all publicly funded acute hospitals. Age-standardised discharge rates by county, sex and all procedures are presented. These allow comparison of discharge rates between populations of different age composition, and also of discharge rates over time. The age-standardised discharge rate (SDR) for an area is the number of discharges (per 100,000) that would occur if that area had the same age structure as the WHO European Standard Population and the local age-specific rates for that area applied. Confidence intervals for these rates are also presented. Standardised Morbidity Ratios (SMRs) are also included. SMRs express the difference between the observed discharges in each county compared to the expected discharges if the age-specific rates of the national population applied. It is presented as a ratio. A ratio that is greater than 100 indicates that county ...
