The Slothful Claw: Osteology and Taphonomy of \u3cem\u3eNothronychus mckinleyi\u3c/em\u3e and \u3cem\u3eN. graffami\u3c/em\u3e (Dinosauria: Theropoda) and Anatomical Considerations for Derived Therizinosaurids

Nothronychus was the first definitive therizinosaurian discovered in North America and currently represents the most specialized North American therizinosaurian genus. It is known from two species, No. mckinleyi from the Moreno Hill Formation (middle Turonian) in west-central New Mexico, and No. graffami from the Tropic Shale (early Turonian) in south-central Utah. Both species are represented by partial to nearly complete skeletons that have helped elucidate evolutionary trends in Therizinosauria. In spite of the biogeographical and evolutionary importance of these two taxa, neither has received a detailed description. Here, we present comprehensive descriptions of No. mckinleyi and No. graffami, the latter of which represents the most complete therizinosaurid skeleton known to date. We amend previous preliminary descriptions of No. mckinleyi and No. graffami based on these new data and modify previous character states based on an in-depth morphological analysis. Additionally, we review the depositional history of both specimens of Nothronychus and compare their taphonomic modes. We demonstrate that the species were not only separated geographically, but also temporally. Based on ammonoid biozones, the species appear to have been separated by at least 1.5 million years and up to 3 million years. We then discuss the impacts of diagenetic deformation on morphology and reevaluate potentially diagnostic characters in light of these new data. For example, the ulna of No. mckinleyi is curved whereas the ulna of No. graffami was considered straight, a character originally separating the two species. However, here we present the difference as much more likely related to diagenetic compression in No. graffami rather than as a true biologic difference. Finally, we include copies of three-dimensional surface scans of all major bones for both taxa for reference

Book Review Of Leap Of Faith By Danielle Steel

Leap of Faith is a novel by a famous novelist Danielle Steel. Leap of Faith debuted at the New York Times and is listed as the best-selling novel to fifty-two of Danielle Steel. This novel is about a girl from France, she is Marie-Ange Hawkins who lives in a magnificent castle name, Chateau de Marmouton. At the castle, she has childhood like everyone\u27s dream.

But the magic happens when Marie-Ange is 21 years old. She makes it back to the castle Chateau de Marmouton again and even get a chance to be the hostess which is the new owner of the castle, Comte Bernard de Beauchamp proposed her. But behind his proposal, Comte Bernard de Beauchamp keeps his hidden bad intentions to Marie-Ange Hawkins.

Danielle Steel packed this book with very interesting by a simple writing style and storyline in the 1800s which is different from the usual. This book is quite interesting and deserves to be read as entertainment by teenagers and adults

Interventions for Challenging Behaviours of Students with Autism Spectrum Disorders and Developmental Disabilities: A Synthesis Paper

This synthesis paper summarizes research literature addressing challenging be-haviours in children and youth with autism spectrum disorders and developmental disabilities in school settings. We conducted a comprehensive literature review to identify relevant peer-reviewed articles published between the years 2000 and 2011. The methodological quality of all studies was screened following a stan-dard quality assessment checklist. Intervention effects were assessed quantitatively. Results of quality analysis and intervention effectiveness were in-tegrated to identify interventions with strong support and evidence of effectiveness. We discuss results in terms of implications for intervention choice and implementation in school settings, limitations, and directions for future re-search
