The Importance of Startups in Job Creation and Job Destruction
Based on Business Dynamics Statistics data, points out the large role start-ups play in new net job creation, patterns of job growth at both start-ups and established firms, and the limitations of current employment policies focused on existing firms
Knowledge Economy Immigration: A Priority for U.S. Growth Policy
Offers economic and political arguments for facilitating immigration of highly educated, skilled workers as a way to support long-term knowledge-based economic growth. Proposes granting green cards to math and science graduates of qualified U.S. colleges
Economic Bloggers Survey
Presents findings from a survey of economic bloggers and economists on the top policy priorities for U.S. economic recovery, the importance of innovation to economic growth and job creation, and barriers to and supports for entrepreneurship
Collaborative and Open Technologies and their Impact on Information Systems Instruction
The advent of the Internet and subsequent proliferation of collaborative technologies are changing the nature of communication and learning. In response, we will stimulate a debate about the role and desired use of collaborative technologies in the context of education in the IS discipline. In particular, we explore the potential contribution of specific technologies based on our practical experience with them. Furthermore, we propose several design principles of using such technologies and illustrate those using working prototypes that we have developed. Finally, we call for participation and further action in realizing the benefits of collaborative technologies in IS education
Neuropsychological Testing of Astronauts
The Spaceflight Cognitive Assessment Tool for Windows (WinSCAT) is a computer program that administers a battery of five timed neuro-cognitive tests. WinSCAT was developed to give astronauts an objective and automated means of assessing their cognitive functioning during space flight, as compared with their own baseline performances measured during similar prior testing on the ground. WinSCAT is also intended for use by flight surgeons to assess cognitive impairment after exposure of astronauts to such cognitive assaults as head trauma, decompression sickness, and exposure to toxic gas. The tests were selected from among a group of tests, denoted the Automated Neuropsychological Assessment Metrics, that were created by the United States Navy and Army for use in evaluating the cognitive impairment of military personnel who have been subjected to medication or are suspected to have sustained brain injuries. These tests have been validated in a variety of clinical settings and are now in the public domain. The tests are presented in a Microsoft Windows shell that facilitates administration and enables immediate reporting of test scores in numerical and graphical forms
The Democratic Biopolitics of PrEP
PrEP (Pre-Exposure Prophylaxis) is a relatively new drug-based HIV prevention technique and an important means to lower the HIV risk of gay men who are especially vulnerable to HIV. From the perspective of biopolitics, PrEP inscribes itself in a larger trend of medicalization and the rise of pharmapower. This article reconstructs and evaluates contemporary literature on biopolitical theory as it applies to PrEP, by bringing it in a dialogue with a mapping of the political debate on PrEP. As PrEP changes sexual norms and subjectification, for example condom use and its meaning for gay subjectivity, it is highly contested. The article shows that the debate on PrEP can be best described with the concepts ‘sexual-somatic ethics’ and ‘democratic biopolitics’, which I develop based on the biopolitical approach of Nikolas Rose and Paul Rabinow. In contrast, interpretations of PrEP which are following governmentality studies or Italian Theory amount to either farfetched or trivial positions on PrEP, when seen in light of the political debate. Furthermore, the article is a contribution to the scholarship on gay subjectivity, highlighting how homophobia and homonormativity haunts gay sex even in liberal environments, and how PrEP can serve as an entry point for the destigmatization of gay sexuality and transformation of gay subjectivity. ‘Biopolitical democratization’ entails making explicit how medical technology and health care relates to sexual subjectification and ethics, to strengthen the voice of (potential) PrEP users in health politics, and to renegotiate the profit and power of Big Pharma
Maverick dark matter at colliders
Assuming that dark matter is a weakly interacting massive particle (WIMP)
species X produced in the early Universe as a cold thermal relic, we study the
collider signal of pp or ppbar -> XXbar + jets and its distinguishability from
standard-model background processes associated with jets and missing energy. We
assume that the WIMP is the sole particle related to dark matter within reach
of the LHC--a "maverick" particle--and that it couples to quarks through a
higher dimensional contact interaction. We simulate the WIMP final-state signal
XXbar + jet and dominant standard-model (SM) background processes and find that
the dark-matter production process results in higher energies for the colored
final state partons than do the standard-model background processes, resulting
in more QCD radiation and a higher jet multiplicity. As a consequence, the
detectable signature of maverick dark matter is an excess over standard-model
expectations of events consisting of large missing transverse energy, together
with large leading jet transverse momentum and scalar sum of the transverse
momenta of the jets. Existing Tevatron data and forthcoming LHC data can
constrain (or discover!) maverick dark matter.Comment: 11 pages, 7 figure
Results from the Wide Angle Search for Planets Prototype (WASP0) I: Analysis of the Pegasus Field
WASP0 is a prototype for what is intended to become a collection of
wide-angle survey instruments whose primary aim is to detect extra-solar
planets transiting across the face of their parent star. The WASP0 instrument
is a wide-field (9-degree) 6.3cm aperture F/2.8 Apogee 10 CCD camera (2Kx2K
chip, 16-arcsec pixels) mounted piggy-back on a commercial telescope. We
present results from analysis of a field in Pegasus using the WASP0 camera,
including observations of the known transiting planet around HD 209458. We also
present details on solving problems which restrict the ability to achieve
photon limited precision with a wide-field commercial CCD. The results
presented herein demonstrate that millimag photometry can be obtained with this
instrument and that it is sensitive enough to detect transit due to extra-solar
planets.Comment: 9 pages, 10 figures, Accepted for publication in MNRA
