  Selection of Baseline Cohorts
The baseline cohorts used in the projections are single-year-of-age cohorts for males and females of Anglo, Black, Hispanic and Other racial/ethnic groups extracted from Summary Tape File 2 from the 1990 Census of Population and Housing.
Special populations are, therefore, generally removed from the cohort base, the base cohorts projected forward and a separate projection of the special population for the projection date is added to the projected base cohorts to obtain the projection of the total population.
For counties with special populations of sufficient size, the baseline cohorts without special populations are projected forward and projections of special populations for the projection years are added to the projections for the baseline cohorts to obtain projections of the total population.

 Seifert & Mandzuk: Cohorts in Teacher Education
Other participants who criticized the cohort also pulled back from outright opposition to the cohort model, but instead described their reason for favoring the status quo as "personal laziness": it took effort to meet new peers, and they felt busy enough as it was.
Under the plan, the cohort sections in the second year would each contain half of the "familiar" students from the first year’s cohort, and half of the new or unfamiliar students from the other cohort section of the stream.
It is unclear, however, whether the cohort model therefore actually impeded the education of students like Nancy, or merely amounted to a sort of diverting "side show" while they focused on their real interest, gaining teacher certification.

 Osteoarthritis Initiative - Longitudinal Studies of Osteoarthritis: State-of-The Science Evaluation   (Site not responding. Last check: 2007-10-19)
The population-based cohorts represent a mix of studies, some of which have recruited representative samples of regions while others have recruited volunteers: the unifying factor is that subjects were not selected on the basis of the presence of existing symptomatic OA.
These cohorts thus offer the possibility of identifying factors associated with the development of anatomic changes of OA as identified primarily by radiograph (magnetic resonance imaging is available in one population-based study [HABC]) as well as examining the relationship between symptoms and activity limitation and anatomic changes of OA in persons from the general population.
In addition, the clinical patient-based cohorts may be useful for validating biomarkers for disease progression, as suggested by preliminary data from the Bristol OA 500 cohort concerning serum levels of C reactive protein and hyaluronic acid and changes in serum levels of cartilage oligomeric matrix protein.

 Working Group on Genome Wide Association in NHLBI Cohorts
A major challenge to GWA studies using existing cohorts is how to combine genotypic and phenotypic data in these multiple datasets; that is, how to mine the observational data and localize disease genes relative to a set of markers, relying on non-random associations between alleles and linkage disequilibrium.
In selecting cohorts for GWA studies it will be important to assess whether candidate studies are managing and curating their phenotypic, clinical, and environmental data in an ongoing fashion.
NHLBI cohorts appear to have incorporated these policies in their distribution of data and specimens internal to the study and in providing access to such resources to ancillary studies.

 LD Prevalence Survival Cohorts Tab
Cases still alive on the desired prevalence date are counted, while adjustments are made to estimate the proportion of cases lost to follow-up that would have made it to the prevalence date.
Use the Survival Cohorts tab to define survival cohorts that are appropriate for your analysis.
It is vital that these cohorts are defined with a level of detail to account for differences in survival, but not so small that the survival statistics are unstable.

 Cohort (statistics) - Wikipedia, the free encyclopedia
In statistics and demography, a cohort is a group of subjects — most often humans from a given population — defined by experiencing an event (typically birth) in a particular time span.
For example, Irish women born in the year 1950 would form a cohort, when studied from a point of view such as their health or mortality, or education, or marriages.
For instance, the total cohort fertility rate is an index of the average completed family size for cohorts of women, but since it can only be known for women who have finished child-bearing, it cannot be measured for currently fertile women.

 European Birth Cohorts
Since the most cost-efficient way to utilise biological samples from cohort studies is on a case-control basis, large sample sizes are required.
The existing birth cohorts are heterogeneous in design and focus, but for specific purposes data from multiple cohorts could be successfully pooled together.
A prerequisite for this strategy is that the cohorts are well documented and that information about design and data on the existing cohorts is collected in a comparable form and easily accessible.

 Comparing the Retirement Savings of the Baby Boomers and Other Cohorts
The Swing cohort is sometimes known as the "silent generation." Members of this cohort came of age after World War II, and many were parents of baby boomers.
Age was measured by the parameters of the four cohorts: the Swing cohort, Older Baby Boomers, Younger Baby Boomers, and Generation X and Y. The Older Baby Boomers were the reference group.
One reason is that the members of this cohort are older, by definition, and some of the respondents had already retired and thus were not included in the sample.

 Description of Cohorts - BPC3
Starting in 1997, follow-up questionnaires have been sent to surviving cohort members every other year to update exposure information and to ascertain occurrence of new cases of cancer; a 90% response rate was achieved for follow-up questionnaires in 1997 and 1999.
The Women's Health Study (WHS) is a randomized trial of low-dose aspirin and vitamin E for the prevention of cardiovascular disease and cancer among 39,876 female health professionals aged 45 years or older at baseline in 1993; 28,263 women provided blood samples prior to randomization.
Cancer follow-up in all these cohorts is conducted by personal mailings and searches of the National Death Index and is estimated to be greater than 90%.

 Will investments in large-scale prospective cohorts and biobanks limit our ability to discover weaker, less common ...   (Site not responding. Last check: 2007-10-19)
Increasing the size of prospective cohorts and biobanks is one approach to discovering previously unknown contributors to complex diseases, but it may come at the price of concealing contributors that are less common across all the participants in those larger studies and of limiting hypothesis generation.
Prospective cohorts and biobanks constitute significant, long-term investments in research infrastructure that will have ongoing consequences for opportunities in biomedical research for the foreseeable future.
In Europe, there is a long tradition of birth cohort studies that extend decades into adulthood, with recent investments in new birth cohorts by the United Kingdom and planning for a "mega" cohort by the European Union (Kogevinas 2002).

Each cohort had four or five ranks (lines) depending upon the number of legionaries in them.
If the day were lost, the legion would retire to the camp using their reserves or the least exhausted troops and the cavalry to cover their retreat.
Since unbroken cohorts couldn't be attacked effectively except along their flanks, cavalry were used most of the time to attack enemy cavalry rather than infantry.

 ARS | Publication request: TILLAGE EFFECT ON REPRODUCTIVE OUTPUT BY FOXTAIL COHORTS IN CORN AND SOYBEAN
Research was conducted in 1996 and 1997 to measure vegetative (primary tiller number per plant) and reproductive output (panicle number and size, and number of seeds produced per plant) at the end of the growing season by three cohorts of green foxtail and yellow foxtail growing in corn and soybean.
The first foxtail cohort (cohort 1) emerged prior to crop emergence, the second cohort (cohort 2) emerged at the same time as crop emergence, and the third cohort (cohort 3) emerged after crop emergence.
Panicle size was variable between years, among tillage systems and cohorts, and between crops and averaged between 3.6 to 5.9 cm for green foxtail and 3.7 to 5.8 cm for yellow foxtail.

 The Wharton School - Undergraduate Division
The ability to cohort our students was facilitated when the faculty approved the new Economics sequence, which allows the Division to keep the entire first-year class together through two semester-long classes (MGMT 100 in the fall, BPUB 250 in the spring).
The success of cohorts at the graduate level has served as a model for the Division, though the focus of cohort activities for the undergraduates will be largely co-curricular in an effort to strengthen the student community.
We are encouraged by the students’ initial reaction to the cohorts this summer as they have already begun “chatting” on both Studentalk and Pennster.

 LESSONS LEARNED WHEN TWO COHORTS SHARED ONE WEB SITE   (Site not responding. Last check: 2007-10-19)
The sharing of a single web site can allow students to interact with a cohort from another state or country, and/or with individuals of different ethnicity, gender, age, etc. A shared web site can thus increase student exposure to elements of diversity that may not be intrinsic to their academic institution.
With the exception of one student, all participants in the latter were students from the distant UCF cohort.
The names of one cohort were typed in all-caps, so it was a simple matter to select students when e-mailing only one of the cohorts, or to establish a student’s cohort-identity in the gradebook.
