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. -

The new taxon, Linheraptor exquisitus gen. et sp. nov., is based on an exceptionally well-preserved, nearly complete skeleton. This specimen represents the fifth dromaeosaurid taxon recovered from the Upper Cretaceous Djadokhta Formation and its laterally equivalent strata, which include the Wulansuhai Formation, and adds to the known diversity of Late Cretaceous dromaeosaurids. Linheraptor exquisitus closely resembles the recently reported Tsaagan mangas. Uniquely among dromaeosaurids, the two taxa share a large, anteriorly located maxillary fenestra and a contact between the jugal and the squamosal that excludes the postorbital from the infratemporal fenestra. -

Resistance, Repression, Responsiveness
RESISTANCE, REPRESSION, RESPONSIVENESS: WORKERS AND THE STATE IN CHINA A Dissertation Presented to the Faculty of the Graduate School of Cornell University in Partial Fulfillment of the Requirements for the Degree of Doctor of Philosophy By Isaac Manfred Elfstrom January 2017 © 2017 Isaac Manfred Elfstrom RESISTANCE, REPRESSION, RESPONSIVENESS: WORKERS AND THE STATE IN CHINA Isaac Manfred Elfstrom, Ph. D. Cornell University 2017 This dissertation examines the impact of labor unrest under authoritarianism. It uses evidence from China to explore the possibility that autocracies, especially state socialist and post-socialist ones, are uniquely vulnerable to worker resistance and therefore react to it in a dual manner, at once repressive and responsive. Drawing on an original dataset of strikes, protests, and riots by Chinese workers, I find that increases in unrest are correlated with both increases in public security spending (repression) and pro-labor rulings in formally adjudicated employment disputes (responsiveness). Using a “most similar” case comparison informed by field theory, I then show how in Jiangsu’s portion of the Yangtze River Delta, moderate industrial contention is paired with governance that can be characterized as preemption, caution, and nudging, while in Guangdong’s portion of the Pearl River Delta, high contention is paired with reaction, experimentation, and crackdowns. Thus, consistent with the dissertation’s quantitative analysis, repression and responsiveness are stronger where resistance is more widespread, but governance is also qualitatively different. I argue that, at the level of local governments and local officials, there is a logic to this divergence between the cases: militant workers make a liability of the state’s commitment to stability, thereby threatening the careers of officials, who must, as a consequence, demonstrate grit and creativity.
