Transcript (64 pages) of interview by Reb DeBirk with Dick Carter, on June 26, 2008Carter (b. 1950) describes his early experiences with his dad, including a memorable trip to Mirror Lake in the High Uintas. He attributes his understanding of what wilderness meant to trips with his Dad when he was a young boy. Dick experienced an "awakening" in high school and college and knew he would be involved in wilderness somehow. Topics discussed include Cliff Merritt (described as "the elder of elders of elders" of the wilderness movement), the Wilderness Society, the Utah Wilderness Association, and the High Uintas Preservation Council. Carter currently concentrates all his efforts on the High Uintas wilderness. Part of the Utah Environmentalist Project. Interviewer: Rob DeBir
Lee-Carter mortality forecasting: a multi-country comparison of variants and extensions
We compare the short- to medium-term accuracy of five variants or extensions of the Lee-Carter method for mortality forecasting. These include the original Lee-Carter, the Lee-Miller and Booth-Maindonald-Smith variants, and the more flexible Hyndman-Ullah and De Jong-Tickle extensions. These methods are compared by applying them to sex-specific populations of 10 developed countries using data for 1986-2000 for evaluation. All variants and extensions are more accurate than the original Lee-Carter method for forecasting log death rates, by up to 61%. However, accuracy in log death rates does not necessarily translate into accuracy in life expectancy. There are no significant differences among the five methods in forecast accuracy for life expectancy.Functional data, Lee-Carter method, mortality forecasting, nonparametric smoothing, principal components, state space.

Hircinia flagelliformis Carter 1886
<i>Hircinia flagelliformis</i> Carter, 1886 <p> <i>Hircinia flagelliformis</i> Carter, 1886a: 372 (no illustration); Hooper & Wiedenmayer 1994: 189.</p> <p> Not: <i>Aplysina flagelliformis</i>; Von Lendenfeld 1889: 415, pl. 27 fig. 10; Wilson 1902: 406.</p> <p> The species was described by Carter from Westernport Bay, Victoria, Australia, approximate coordinates 38,35°S 145.24°E (lectotype (dried) BMNH 1886.12.15.242). The description is unclear in the sense that Carter mentions filaments (a distinctive feature of genus <i>Ircinia</i>), but reports that these contain sand grains, which is not known from any <i>Ircinia</i>. Furthermore, he makes a comparison with the species <i>Aplysina longissima</i> described by him from the West Indian region (Bahamas and Jamaica), which is currently assigned to the haplosclerid <i>Callyspongia (Cladochalina) tenerrima</i> (Duchassaing & Michelotti, 1864). Von Lendenfeld (1889) translated Carter’s remark to an assignment to the genus <i>Aplysina</i> as <i>A. flagelliformis</i>, supposedly occurring disjunctly in Australia and the West Indian region, without re-examining the specimen (contra a suggestion by Hooper & Wiedenmayer 1994: 189). Wilson (1902) followed this by describing <i>Aplysina flagelliformis</i> from Puerto Rico, which is a true <i>Aplysina</i>, probably <i>A. fulva</i> (Pallas, 1766) or <i>A. cauliformis</i> (Carter, 1882a). Hooper & Wiedenmayer listed the species as Druinellidae Von Lendenfeld, 1889 <i>incertae sedis</i> (= currently Pseudoceratinidae Carter, 1885a <i>incertae sedis</i>). The identity of <i>Hircinia flagelliformis</i> remains uncertain and thus it is best to keep its name <i>Ircinia flagelliformis</i> Carter, 1886a for the time being but as a <i>taxon inquirendum</i>.</p>Published as part of <i>Van Soest, Rob W.

Letter from Wayne Carter to Oscar Monnig
Letter from Wayne Carter to Oscar Monnig about the McKinney meteorite.Mailed 6/14 Route 1 McKinney Texas. June 12th, 1937. Dear Sir; My neighbor that lives on the next farm east of us has a meteorite. It is of the same stony and metal type as the one I found. But it isn't shaped like it. It is shaped something like this [sketch of oval] and weighs two pounds. Mr. Rob Furr is the mans name that found it. He said for me to write you about it. If I had known it thirty minutes earlier you could have gotten it while you were down here. He found it before you all went back toward McKinney but didn't quite know wheather it was a meteorite or not. I think it is probably a piece of the same one I found. Yours truly, Wayne Carter not met 7/3/37 Artificial cast iron piect I went visiting this evening and heard that a boy living about a mile east of me has two pieces (old marble) of a meteorite I haven't seen them but think probably he may have some. Say: That picture I drew doesn't look much like the meteorite. It is shaped more like a cake of hand soap. Collin - Tex On McKinney mets, talked Marshall Carter & W.F.

Halisarca australiensis var. arenacea Carter 1886
<i>Halisarca australiensis</i> var. <i>arenacea</i> Carter, 1886 <p> <i>Halisarca australiensis</i> var. <i>arenacea</i> Carter, 1886a: 277 (no illustration); Hooper & Wiedenmayer 1994: 528.</p> <p> The variety was described by Carter from Port Phillip Heads, Victoria, Australia, approximate coordinates 38.3°S 114.61°E, collected by J.B. Wilson (wet holotype BMNH 1887.7.11.2). Hooper & Wiedenmayer (1994: 528) took up this variety along with the typical variety under their chapter ‘Species Inquirendae’ because Carter’s descriptions of the <i>Halisarca</i> specimens from SE Australia appear to indicate they could be asidians (Tunicata) rather than sponges. The present variety is stated to differ from the typical variety (syntype BMNH 1887.7.11.1 and 4, collected at the same locality and also by J.B. Wilson) in being lighter colored, presumed to be caused by a cover of crystal sand. The original description of <i>Halisarca australiensis</i> Carter (1885a:197) was expanded in his 1886a paper into four species and the present variety. Apparently these are all similar in shape and size and differ only in minor details. In view of the poor evidence provided by Carter, I propose here to merge the var. <i>arenacea</i> with the typical variety into a single species <i>Halisarca australiensis</i> Carter, 1885a as a <i>taxon inquirendum</i>.</p>Published as part of <i>Van Soest, Rob W.

Lee-Carter mortality forecasting: a multi-country comparison of variants and extensions
Heather Booth, Rob J. Hyndman, Leonie Tickle and Piet de Jong compare the short- to medium- term accuracy of five variants or extensions of the Lee-Carter method for mortality forecasting
Teaching MSK Anatomy: A movement-based perspective.
In the presentation we will explore…
1. Why we developed a movement based perspective with a look at an abridged MSK Clinical Assessment (Such as a Physio or SRT would need to do)
2. How we ensure this as part of our PTY103 ‘Functional Anatomy and Movement’ Module. Here we will look at the Pedagogy and contrast traditional to kinaesthetic approach.
3. Current and future developments with integration of Cadaveric specimens and links with Anatomy Centre. Ivan will extol the benefits of teaching using the soft fix and how such developments will support and improve the education of our students moving forward
Robust forecasting of mortality and fertility rates: a functional data approach
We propose a new method for forecasting age-specific mortality and fertility rates observed over time. Our approach allows for smooth functions of age, is robust for outlying years due to wars and epidemics, and provides a modelling framework that is easily adapted to allow for constraints and other information. We combine ideas from functional data analysis, nonparametric smoothing and robust statistics to form a methodology that is widely applicable to any functional time series data, and age-specific mortality and fertility in particular. We show that our model is a generalization of the Lee-Carter model commonly used in mortality and fertility forecasting. The methodology is applied to French mortality data and Australian fertility data, and we show that the forecasts obtained are superior to those from the Lee-Carter method and several of its variants.Fertility Forecasting, Functional Data, Mortality Forecasting, Nonparametric Smoothing, Principal Components, Robustness.
