    Looking Through the (Mis)Classifieds: Why TaskRabbit is Better Suited than Uber and Lyft to Succeed Against a Worker Misclassification Claim

    In the highly competitive gig-economy, companies are constantly trying to leverage whatever they can to gain a competitive advantage over competitors. One method of doing so is saving on employment costs by classifying workers as independent contractors. There are two ways to accomplish this: (1) structure the business as an internet-based marketplace or platform; or (2) structure the relationship between the business and the worker in a way that ensures the worker remains classified as an independent contractor under either the common law control test or the economic realities test. Both Uber and Lyft have faced accusations of intentionally misclassifying their workers to utilize this competitive advantage. Taking an in-depth look at Uber’s and Lyft’s business models reveals that both companies have failed to accomplish either of the two methods above, indicating their workers may in fact be misclassified. TaskRabbit’s model, on the other hand, has key distinguishing characteristics that make it more of a marketplace than Uber or Lyft while also allowing for proper classification of its workers as independent contractors under both the common law control and the economic realities tests. Therefore, TaskRabbit’s model allows the company to legally enjoy the benefits of classifying its workers as independent contractors, providing it a competitive edge in the gig-economy

    Redescription of \u3ci\u3eAnovia circumclusa\u3c/i\u3e (Gorham) (Coleoptera: Coccinellidae: Noviini), with First Description of the Egg, Larva, and Pupa, and Notes on Adult Intraspecific Elytral Pattern Variation

    Anovia circumclusa (Gorham), a neotropical lady beetle, recently was recorded in North America for the first time. Previously, only the adult form of this beneficial predator had been described. This paper provides a redescription of the adult and the first descriptions of the egg, larva, and pupa. Diagnostic characters for the genus and species are given, and intraspecific color variation in Anovia adults is discussed

    Optimal combination of signals from co-located gravitational wave interferometers for use in searches for a stochastic background

    This article derives an optimal (i.e., unbiased, minimum variance) estimator for the pseudo-detector strain for a pair of co-located gravitational wave interferometers (such as the pair of LIGO interferometers at its Hanford Observatory), allowing for possible instrumental correlations between the two detectors. The technique is robust and does not involve any assumptions or approximations regarding the relative strength of gravitational wave signals in the detector pair with respect to other sources of correlated instrumental or environmental noise. An expression is given for the effective power spectral density of the combined noise in the pseudo-detector. This can then be introduced into the standard optimal Wiener filter used to cross-correlate detector data streams in order to obtain an optimal estimate of the stochastic gravitational wave background. In addition, a dual to the optimal estimate of strain is derived. This dual is constructed to contain no gravitational wave signature and can thus be used as on "off-source" measurement to test algorithms used in the "on-source" observation.Comment: 14 pages, 4 figures, submitted to Physical Review D Resubmitted after editing paper in response to referee comments. Removed appendices A, B and edited text accordingly. Improved legibility of figures. Corrected several references. Corrected reference to science run number (S1 vs. S2) in text and figure caption

    Fast graph operations in quantum computation

    The connection between certain entangled states and graphs has been heavily studied in the context of measurement-based quantum computation as a tool for understanding entanglement. Here we show that this correspondence can be harnessed in the reverse direction to yield a graph data structure, which allows for more efficient manipulation and comparison of graphs than any possible classical structure. We introduce efficient algorithms for many transformation and comparison operations on graphs represented as graph states, and prove that no classical data structure can have similar performance for the full set of operations studied

    Progress on stochastic background search codes for LIGO

    One of the types of signals for which the LIGO interferometric gravitational wave detectors will search is a stochastic background of gravitational radiation. We review the technique of searching for a background using the optimally-filtered cross-correlation statistic, and describe the state of plans to perform such cross-correlations between the two LIGO interferometers as well as between LIGO and other gravitational-wave detectors, in particular the preparation of software to perform such data analysis.Comment: 7 pages, 1 encapsulated PostScript figure, uses IOP class files, submitted to the proceedings of the 4th Amaldi meeting (which will be published in Classical and Quantum Gravity
