Tim Fox 91435 Horse Creek Road McKenzie Bridge , OR 97413 (541) 822-8055 [email protected] The Mountain Lion By Tim Fox . I suspect that the mind, like the feet, works at about three miles an hour. If this is so, then modern life is moving faster than the speed of thought, or thoughtfulness. Rebecca Solnit Wanderlust: A History of Walking Fox/Mountain Lion/ Page 2 Overture Overture: An act, offer, or proposal that indicates readiness to undertake a course of action or to open a relationship. American Heritage Dictionary Each September 28th for the past eight years, I have embarked on a reading of Peter Matthiessen’s classic The Snow Leopard. I work my way through his daily entries on the same date he wrote them in 1973 until, on December 1st, the chronicle of his remarkable journey across the Himalayas and into himself, comes to an end. What I find particularly moving about the book, beyond the beautiful language, profound insights and stunning natural and cultural setting, is the mode of mobility that frames Matthiessen’s experience. It all takes place afoot, which gives the text a rare continuity. What if Matthiessen (henceforth PM) had driven or flown from Pokhara to the Crystal Monastery and back? No doubt, his journey and resultant book would have been completely different. This awareness helped inspire my Long Term Ecological Reflections residency. Unlike the other residency recipients to date, I have a relatively long-term (fifteen-year) and multi-faceted relationship with the Andrews Forest. Yet, until last summer, I had always ridden in automobiles to access my various destinations -- headquarters, owl sites, vegetation plots, trailheads etc. -
NASAT 2013 Round #5
NASAT 2013 Round 5 Tossups 1. In this novel, a priest who has a marvelous collection of masks is found beheaded in a patch of hyacinths. That character, Father Huismans, teaches the son of Zabeth, a magician. The servant Ali takes the name Metty before coming to work with the protagonist of this novel, whose friend Indar says that his home country is not strong since they do not have a flag. The protagonist of this novel has an affair with Yvette, whose husband Raymond works in an area called the Domain for a ruler called the Big Man.

In one piece, this composer memorialized an incident in which a crowd waiting at a train station spontaneously broke out into song. Nicholas Slonimsky instructed part of his ensemble to play four measures in the same time that another part played three to evoke dueling bands in his rendition of another "orchestral set" by this composer. He instructed the pianist to create a tone cluster by hitting the keys with a piece of wood in the "Hawthorne" movement of another work. This composer used minor thirds in his quotations of songs like "Old Black Joe" in the first movement of his most famous piece, which depicts the Robert Gould Shaw Memorial. For 10 points, name this American composer of Concord Sonata and Three Places in New England. -
Review of the Year
Review of the year 2014-2015 welcome Welcome It is a pleasure, as the University of Bristol’s new Vice-Chancellor and President, to introduce the Review of the Year for 2014-15. I cannot take any credit for the successes described in this report, but reading it made me feel even more proud to have joined this great University. On 2 September 2015 I became the University’s 13th Vice-Chancellor. I would like to pay tribute to Sir Eric Thomas for all he, and the University, achieved under his 14-year reign. I have taken over a university with an outstanding reputation for research and teaching, which is a destination of choice for many more excellent students than we are able to accommodate. Talking to my colleagues, there are a few moments over the past year that stand out. One of the foremost has to be coming fifth for research intensity in the UK in the Research Excellence Framework. Other high points included the opening of the new state-of-the- art Life Sciences building and the refurbished Richmond Building. The latter, with its study spaces, studios, bars and cafés, is Picture: Nick Smith transforming our students’ experience. Before I came to Bristol I was President and Chief Officer of University College Dublin for 10 years, and during that time led the organisation through some necessary, if occasionally painful, changes. Bristol is a very different proposition. I have already sensed ambition from my new colleagues to build on the excellent foundation we have and take a step forward, and over the next year I will be developing a new vision and strategy collaboratively with my colleagues, our students and the wider Bristol family. -
A New Raptorial Dinosaur with Exceptionally Long Feathering Provides Insights Into Dromaeosaurid flight Performance
ARTICLE Received 11 Apr 2014 | Accepted 11 Jun 2014 | Published 15 Jul 2014 DOI: 10.1038/ncomms5382 A new raptorial dinosaur with exceptionally long feathering provides insights into dromaeosaurid flight performance Gang Han1, Luis M. Chiappe2, Shu-An Ji1,3, Michael Habib4, Alan H. Turner5, Anusuya Chinsamy6, Xueling Liu1 & Lizhuo Han1 Microraptorines are a group of predatory dromaeosaurid theropod dinosaurs with aero- dynamic capacity. These close relatives of birds are essential for testing hypotheses explaining the origin and early evolution of avian flight. Here we describe a new ‘four-winged’ microraptorine, Changyuraptor yangi, from the Early Cretaceous Jehol Biota of China. With tail feathers that are nearly 30 cm long, roughly 30% the length of the skeleton, the new fossil possesses the longest known feathers for any non-avian dinosaur. Furthermore, it is the largest theropod with long, pennaceous feathers attached to the lower hind limbs (that is, ‘hindwings’). The lengthy feathered tail of the new fossil provides insight into the flight performance of microraptorines and how they may have maintained aerial competency at larger body sizes. We demonstrate how the low-aspect-ratio tail of the new fossil would have acted as a pitch control structure reducing descent speed and thus playing a key role in landing. 1 Paleontological Center, Bohai University, 19 Keji Road, New Shongshan District, Jinzhou, Liaoning Province 121013, China. 2 Dinosaur Institute, Natural History Museum of Los Angeles County, 900 Exposition Boulevard, Los Angeles, California 90007, USA. 3 Institute of Geology, Chinese Academy of Geological Sciences, 26 Baiwanzhuang Road, Beijing 100037, China. 4 University of Southern California, Health Sciences Campus, BMT 403, Mail Code 9112, Los Angeles, California 90089, USA. -

A review of studies of sexual dimorphism in the vertebrate fossil record revealed methods that were selected for use in ceratopsids. Mountain goats, bison, and pronghorn were selected as exemplar taxa for a proof of principle study that tested the selected methods, and informed and guided the investigation of sexual dimorphism in dinosaurs. Skulls of these exemplar taxa were measured in museum collections, and methods of analysing morphological variation were tested for their ability to demonstrate sexual dimorphism in their horns and horncores. -

Difficulties with the Origin of Dinosaurs: a Short Comment on the Current Debate
REVIEW ARTICLE Difficulties with the origin of dinosaurs: a short comment on the current debate MATTHEW G. BARON BPP University, 144 Uxbridge Road, London W12 8AA, UK E-mail: [email protected] Abstract: The origin and early evolutionary history of the dinosaurs is a topic that has recently gone through a period of renewed interest and academic debate. For 130 years, one way of classifying the various dinosaur subgroups persisted as the accepted model, with increasing levels of research in the past quarter-century also providing evidence for the hypothesis that dinosaur origination occurred in the Southern Hemisphere, particularly in South America. It is, after all, from within the Late Triassic strata of countries like Argentina and Brazil that we get some of the very best early dinosaur specimens; many of these specimens are the earliest known representatives of some of the major dinosaur subgroups, such as the theropods and sauropodomorphs. However, some recent analyses have brought about a shift in terms of what is currently accepted and what is now disputed regarding the origin of dinosaurs – the Southern Hemisphere origination hypothesis was questioned (although this was based upon observations and not with quantitative analysis techniques), as has the shape of the dinosaur tree. Responses to the new hypothesis were numerous and robust, and new analyses further supported a Southern Hemisphere point of origin. Whilst the interrelationships between the major dinosaur clades remains to be fully resolved, the current data does seem to comprehensively answer the question of where the dinosaurs first originated. However, it is arguable whether or not the current data that is being used in such palaeobiogeographical analyses is sufficient to provide a meaningful answer to the question of where specifically the dinosaur clade first appeared.
