Understanding the Meaning of Fatigue at the End of Life: An Ethnoscience Approach
No full textPurpose: Fatigue is a devastating state of body and mind associated with distress at the end of life. We report the results of the third in a series of papers outlining a novel approach we have developed for understanding the meaning of fatigue by exploring how this meaning is shaped by beliefs and values. The aims of the study were to examine the perception and experiences of fatigue held by patients attending a hospice in England; identify the behavioural patterns that distinguish fatigue from tiredness and exhaustion; provide conceptual definitions of tiredness, fatigue and exhaustion.
Method: An Ethnoscience design was selected. The sample comprised nine people who attended a hospice between May and December 2009. Inclusion criteria included: at least 18 years of age, experiencing fatigue, able to provide informed consent and resident in the selected city in northern England for 10 years. Data were collected from two consecutive semi-structured interviews for each participant.
Results: We found that tiredness, fatigue and exhaustion are markers of progressive functional decline. Fatigue had two dimensions: 1) Mental Challenge, which included: emotional effects, cognitive realisation of decline and mental tenacity and 2) Physical Challenge, which included: limitations in leisure activities, limitations in functional roles and re-patterning routines.
Conclusions: This study provides evidence that symptom experience is socially constructed, which has potential implications for the development of effective interventions
Letter dated 26 May 1970 from Gerald W. Olson to A. A. Klingebiel

Klingebiel, Director of Soil Survey Interpretations at the Soil Conservation Service, Washington, D.C.; this is a copy sent to Lorenzo A. Richards, regarding soil surveys in Venezuela and seeking permission to translate a book into SpanishNEW YORK STATE COLLEGE OF AGRICULTURE A STATUTORY COLLEGE OF THE STATE UNIVERSITY CORNELL UNIVERSITY ITHACA, N. Y. 14850 DEPARTMENT OF AGRONOMY BRADFIELD AND EMERSON HALLS May 26, 1970 Mr. A. A. Klingebiel Director of Soil Survey Interpretations Soil Conservation Service U. S. Department of Agriculture Washington, D. C. Dear Mr. Klingebiel: Recently I have been impressed with the beginning work in soil survey interpretations in Venezuela. I think that the Soil Science Society of America and other institutions and agencies using soils information in the U.S.A. should assist and encourage this new work in every way possible. Attached is a letter requesting permission to translate the book Soil Surveys and Land Use Planning into Spanish for distribution in Venezuela and Latin America. Because of your excellent work in the editorial genesis of the book, I am forwarding this request to you and am asking that you follow up on it. I will be glad to do whatever I can to assist in any way possible, but will be out of the country from June 15-August 15 doing soil studies with the Cornell - Harvard Archaeological Expedition at Sardis, Turkey. Probably you will want to communicate directly Sincerely, siLJA U). 0JL* Gerald W. Olson Asst. Prof, of Soil Science in Resource Development with Mr. Pedro Jose Urriola - Munoz. cc R. Abreu J.V.

No full textCitation: Hill, S. L., Grieger, D. M., Olson, K. C., Jaeger, J. R., Dahlen, C. R., Crosswhite, M. R., . . . Stevenson, J. S. (2016). Gonadotropin-releasing hormone increased pregnancy risk in suckled beef cows not detected in estrus and subjected to a split-time artificial insemination program. Journal of Animal Science, 94(9), 3722-3728. doi:10.2527/jas2016-0582We hypothesized that GnRH would increase pregnancy risk (PR) in a split-time AI program for cows in which estrus was not detected. A total of 1,236 suckled beef cows at 12 locations in 3 states (Colorado, Kansas, and North Dakota) were enrolled. Before applying the fixed-time AI program, BCS was assessed. Cows were treated on d -7 with a progesterone insert concurrent with 100 mu g GnRH and on d 0 with 25 mg PGF(2 alpha) plus removal of the insert. Estrus-detection patches were affixed to cows at insert removal. Estrus was defined to have occurred when an estrus-detection patch was >50% colored (activated). Cows in estrus by 65 h (n = 758; 61.3% of all cows) were randomly allocated to 2 treatments: 1) 100 mu g GnRH and early + GnRH (E+G; n = 373) or 2) AI only at 65 h (early -no GnRH [E-G]; n = 385). The remaining cows were randomly allocated to 2 treatments: 1) 5(L+G; n = 252) or 2) AI only at 84 h (late no GnRH [L-G]; n = 226). Pregnancy was determined 35 d after AI via transrectal ultrasound. Pregnancy risk did not differ (P = 0.68) between E+G and E-G cows (61.9 vs. 60.4%, respectively). Conversely, for cows inseminated at 84 h, PR was greater (P = 0.01) in cows that received GnRH (L+G) compared with their herd mates not receiving GnRH (L-G; 41.7 vs. 30.8%, respectively). Of those cows not detected in estrus by 65 h, 42.1% were detected by 84 h, for a total expression of estrus by all cows of 77.6%. Administration of GnRH increased (P < 0.01) PR in cows not detected in estrus by 84 h (+ GnRH = 33.4% [n = 146] vs. no GnRH = 15.0% [n = 128]) but had no effect in cows expressing estrus by 84 h (+ GnRH = 65.3% [n = 103] vs. no GnRH = 61.7% [n = 97]). Neither estrus expression by 65 or 84 h nor PR was influenced by BCS, parity, or days postpartum at AI. Cows had greater PR when they had been detected in estrus before AI, and PR was improved by administration of GnRH at 65 h after insert removal in cows that were not detected in estrus and inseminated at 84 h
The Mountain Pass Rare-Earth Deposits
No full textRare-earth minerals were discovered near Mountain Pass in northeastern San Bernardino County, Calif., in April 1949, and in the following year the Sulphide Queen carbonate body was found. This body is the world's greatest known concentration of rare-earth metals with a tonnage larger than the total of all rare earths used in the world prior to 1950. The rare earths in the Mountain Pass district are chiefly cerium, lanthanum, and neodymium.
These elements occur principally in bastnaesite, a rare-earth fluocarbonate, heretofore reported from only about 10 localities in the world.
The bastnaesite was discovered in samples from Mountain Pass obtained by H. E. Woodward and Clarence Watkins of Goodsprings, Nev., and its identity was established in laboratory studies by E . T. Schenk of the U. S. Bureau of Mines and D. F. Hewett of the U. S. Geological Survey. Subsequent prospecting by individuals and geologic investigations by the U. S. Geological Survey resulted in the discovery of bastnaesite in the Sulphide Queen carbonate body and numerous other deposits in a belt 6 miles long.
Investigations by the U. S. Geological Survey since 1949 (Olson et al., in preparation) include detailed mapping of the site of the initial discovery-the Birthday claims-by L. C. Pray and W. N. Sharp; geologic mapping of the district by J. C. Olson; detailed mapping of the Sulphide Queen carbonate body and several smaller deposits by D. R. Shawe and W. N. Sharp; and laboratory mineralogic investigations by H. W. Jaffe
