Myrmecotypus O. Pickard-Cambridge 1894
No full textMyrmecotypus O. Pickard-Cambridge, 1894 Myrmecotypus O. Pickard-Cambridge, 1894: 123; Reiskind, 1969: 270. Type species by monotypy: Myrmecotypus fuliginosus O. Pickard-Cambridge, 1894. Diagnosis. Myrmecotypus can be distinguished from other corinnid genera by: (1) the absence of a thoracic groove, (2) a narrowed carapace (carapace index less than 60), (3) wide cephalic region (cephalic index range 64–89), (4) PER nearly straight and only slightly wider then AER, (5) PME–PME greater then PME–PLE (Reiskind 1969; Rubio & Arbino 2009).Published as part of Leister, Matthew & Miller, Kelly, 2014, A new species of ant mimicking spider, Myrmecotypus jasmineae (Araneae: Corinnidae: Castianeirinae), from Nicaragua, pp. 495-500 in Zootaxa 3838 (4) on page 495, DOI: 10.11646/zootaxa.3838.4.8, http://zenodo.org/record/23049
Sphecotypus O. Pickard-Cambridge 1895
No full textSphecotypus O. Pickard-Cambridge, 1895 Sphecotypus O. Pickard-Cambridge, 1895: Type species, Sphecotypus formicarius O. Pickard-Cambridge, 1895 = S. niger (Perty, 1833). Diagnosis. Sphecotypus resembles Myrmecium Latreille, 1824, in having deep constrictions on a narrowed carapace, but can be distinguished from this genus and other Castianeirinae by having: (1) only one deep constriction of the carapace, which is behind the cephalic region clearly separating the cephalic and thoracic regions; and (2) the prolongation of the sternum in front of the first coxae, producing a “neck” (Fig. 1 A–C) (Reiskind 1969; Deeleman-Reinhold 2001). In addition Sphecotypus differs from Myrmecium by having all coxae evenly spaced, and all emerging from beneath the thoracic region of the carapace (Fig. 1 A–C), whereas the first two coxae in Myrmecium are spaced close to each other and emerge from beneath the cephalic region of the carapace (O. Pickard-Cambridge 1895).Published as part of Leister, Matthew & Miller, Kelly, 2014, First description of the male of Sphecotypus niger (Perty, 1833), with notes on behavioral and morphological mimicry (Araneae: Corinnidae: Castianeirinae), pp. 146-150 in Zootaxa 3814 (1) on pages 146-147, DOI: 10.11646/zootaxa.3814.1.10, http://zenodo.org/record/23078
Can we Help the Bots? Towards an Evaluation of their Performance and the Creation of Human Enhanced Artifact for Emotions De-escalation
No full textWe propose a hybrid intelligence socio-technical artifact that identifies a threshold where the chatbot requires human intervention in order to continue to perform at an appropriate level to achieve the pre-defined objective of the system. We leverage the Yield Shift Theory of Satisfaction, the Intervention Theory and the Nudge Theory to develop meta requirements and design principles for this system. We discuss the first iteration of implementation and evaluation of the artifact components
Theoretical investigations of oxygen-17 NMR chemical shifts to discriminate among helical forms
No full textO-17, N-15, C-13, and H-1 NMR chemical shieldings are calculated using density functional theory to differentiate among the three primarily helical forms, 3(10), alpha, and pi in polyalanine peptides under periodic boundary conditions. This study suggests O-17 as the best observable, as it has been demonstrated to be sensitive to hydrogen bonding and highly affected by small changes in the polypeptide in helix conformations. This theoretical study seeks to characterize the subtle conformational differences of helical structures by NMR chemical shift observables which may lead to important questions in experimental structure determination on the basis of using chemical shifts to identify protein secondary structures
America’s Battle for Media Democracy: The Triumph of Corporate Libertarianism and the Future of Media Reform
No full textThis contribution is a recording of the CAMRI research seminar held at the University of Westminster on November 19, 2014, in which Victor Pickard presented his book "America’s Battle for Media Democracy: The Triumph of Corporate Libertarianism and the Future of Media Reform": http://www.cambridge.org/gb/academic/subjects/politics-international-relations/american-government-politics-and-policy/americas-battle-media-democracy-triumph-corporate-libertarianism-and-future-media-reform
Why do American media have so few public interest regulations? How did the American media system become dominated by a few corporations, and why are structural problems like market failures routinely avoided in media policy discourse?
By tracing the answers to many of these questions back to media policy battles in the 1940s, Victor Pickard explains how this happened and why it matters today. Drawing from extensive archival research, the book uncovers the American media system’s historical roots and normative foundations. His book charts the rise and fall of a forgotten media reform movement to recover alternatives and paths not taken. As much about the present and future as it is about the past, the book proposes policies for remaking media based on democratic values for the digital age.
Victor Pickard is an assistant professor at the Annenberg School for Communication at the University of Pennsylvania. Previously he taught media studies at NYU and the University of Virginia, and he worked on media policy in Washington, D.C. as a Senior Research Fellow at the media reform organization Free Press, the public policy think tank the New America Foundation, and Congresswoman Diane Watson’s office.
He has published numerous journal articles and book chapters on the history and political economy of media institutions and media reform activism. His op-eds on media policy debates and the future of journalism have appeared in news outlets like The Guardian, The Seattle Times, The Huffington Post, and The Philadelphia Inquirer. He is the editor (with Robert McChesney) of Will the Last Reporter Please Turn out the Lights, and the author of America’s Battle for Media Democracy. He tweets at @VWPickard
Adult literacy learners in contemporary context: "education debt," unpaid
No full textThe publicly-funded adult literacy system constitutes the largest network of available adult basic education (ABE) programs (Beder, 1991). However, since the 1998 Workforce Investment Act (WIA) instituted accountability measures related to ABE students’ standardized test performance and their rapid acquisition of jobs, researchers and practitioners have been concerned that programs were implicitly being forced to limit program access for adults who have difficulty with reading, among whom students of color are disproportionately concentrated (Beder, 1999; Comings, 2007; Condelli, 2007; Pickard, 2016). With the 2014 Workforce Innovation and Opportunity Act’s added emphasis on rapid transition of adult literacy students into post-secondary education, this concern has intensified (Pickard, 2016). This ethnographic study explored the experiences of learners enrolled in a publicly-funded ABE class targeted to adults who have difficulty reading and examined the relationship between the federal policies that fund and regulate adult literacy programs and these learners’ classroom experiences. Findings include that learners in this class encountered significant barriers of access to public literacy programs, were exposed to deficit-based programmatic practices that possibly worsened their educational marginalization, and had their cultural and personal strengths largely ignored during classroom instruction. Furthermore, it was observed that the pressures of federal accountability policy activated or deepened these practitioners’ deficit beliefs about learners. Critical race theory (CRT) methodology (Solórzano & Yosso, 2002) was used to construct counter-stories that focus on learners’ strengths and to imagine opportunities for adult literacy instruction that are grounded in learner assets, rather than driven by deficit beliefs. Ladson-Billings (2006) argued that there is an “education debt” owed to racially minoritized students in the U.S., rooted in the highly discriminatory “historical, economic, sociopolitical, and moral decisions and policies” (p.5) that shape our society and our educational systems. Similarly, the literacy issues of adults who have difficulty reading have been influenced by a multitude of complex, interwoven sociopolitical and educational factors. This study found that participation in a publicly-funded adult literacy class left the education debt owed to these learners largely unpaid.Ph.D.Includes bibliographical referencesby Amy Pickar
Clear interests and clouded future : force structure and strategy options for the People's Liberation Army Navy (PLAN)
No full textThesis (S.M.)--Massachusetts Institute of Technology, Dept. of Political Science, 2007.Includes bibliographical references (leaves 115-121).As China's participation in the global economy continues to expand, its increasing reliance on imported resources and overseas trade has exerted pressure on China to safeguard its growing maritime economic and political interests. Although Chinese national interests are well understood, there is no clear consensus regarding the long-term orientation or intended goals of China's modernizing military. By examining how sea power theory, maritime interests, economic and political constraints, and military/naval doctrine may influence China's naval force structure and maritime strategy, the author seeks to answer whether it is possible to deduce the most probable future roles of the People's Liberation Army Navy (PLAN). This paper suggest the answer is yes and identifies three force structure and maritime strategy models that the PLAN may utilize to support China's expanding global and maritime interests. The author posits that the PLAN will continue to make quantitative and qualitative improvements, but due primarily to fiscal and technological constraints, China will not directly challenge the United States by matching its extensive multiple mission naval force structure. The PLAN is still in a nascent stage of development and already has many of the pieces in place to proceed toward each model presented, but China must make choices that require it to develop the PLAN in conjunction with specific and elaborated maritime strategies or risk being a "jack-of-all-trades and a master of none." The PLAN will therefore develop either as 1) a "Unification" Navy, maximizing coercive pressure on Taiwan by focusing on regional anti-access strategies; 2) an "Influence Projection" Navy, capable of a wide range of operations, but not with a capability nearing a U.S. carrier strike group; or 3) a "Global/Hemispheric Sea Denial"(cont.) Navy, designed around a fleet of ultra-quiet nuclear attack submarines, designed to deter a major naval power from dominating China's vital sea lines of communication. Although there is considerable variation in opinion and analysis as to the exact direction of China's grand strategy, the author identifies these models as the most logical force structure and maritime strategies that China might pursue in support of its maritime interests.by Kevin Pickard, Jr.S.M
