    Homo Datumicus : correcting the market for identity data

    Get PDF
    Effective digital identity systems offer great economic and civic potential. However, unlocking this potential requires dealing with social, behavioural, and structural challenges to efficient market formation. We propose that a marketplace for identity data can be more efficiently formed with an infrastructure that provides a more adequate representation of individuals online. This paper therefore introduces the ontological concept of Homo Datumicus: individuals as data subjects transformed by HAT Microservers, with the axiomatic computational capabilities to transact with their own data at scale. Adoption of this paradigm would lower the social risks of identity orientation, enable privacy preserving transactions by default and mitigate the risks of power imbalances in digital identity systems and markets

    The Impact of Terrain and Other Factors on Wild Fires

    Wild fires have become an annual concern in the United States, and despite the vast amount of resources and manpower used to combat the spread of wild fires, the success rate tends to vary. With this in mind, a research project has commenced which is primarily aimed at discovering the relationship between environmental factors and wild fire growth, or lack of growth. This research analyzes data available in the Google Earth Engine and includes geographical features such as roads and elevation. Using Google Earth Engine programs, the goal is to establish meaningful relationships between a fire’s growth and various environmental elements. The investigation will be largely focused on individual fires as a means to establish a correlation between the environmental factors and the development of wild fires. It is conceivable that a closer look at these different relationships will increase the understanding of how these factors can influence wild fires, and consequentially, lead to the use of improved strategies that will result in potentially higher success in the combating of future wild fires

    Abstract - Wild fires have become an annual concern in the United States, and despite the vast amount of resources and manpower used to combat the spread of wild fires, the success rate tends to vary. With this in mind, a research project has commenced which is primarily aimed at discovering the relationship between environmental factors and wild fire growth, or lack of growth. This research analyzes data available in the Google Earth Engine and includes geographical features such as roads, elevation, and other factors like humidity and wind. Using Google Earth Engine programs, the goal is to establish meaningful relationships between a fire’s growth and various environmental elements. The investigation will be largely focused on individual fires as a means to establish a correlation between the environmental factors and the development of wild fires. It is conceivable that a closer look at these different relationships will increase the understanding of how these factors can influence wild fires, and consequentially, lead to the use of improved strategies that will result in potentially higher success in the combating of future wild fires

    An Incentives Approach to Improving the Unemployment Compensation System

    Get PDF
    Overpayments may account for up to 15 percent of all payments made under the unemployment compensation system. Burgess and Kingston propose that this overpayment serves as a clue to the more serious problems residing in the system. The authors focus on the lack of incentives (or the existence of disincentives) for improvement within the UC program structure for all participants - claimants, employers, and state UC agencies. Other issues they explore include the excessive complexity of the system and the difficulty of effectively monitoring claimant compliance with eligibility criteria.https://research.upjohn.org/up_press/1116/thumbnail.jp

    Anomalously small wave tails in higher dimensions

    Full text link
    We consider the late-time tails of spherical waves propagating on even-dimensional Minkowski spacetime under the influence of a long range radial potential. We show that in six and higher even dimensions there exist exceptional potentials for which the tail has an anomalously small amplitude and fast decay. Along the way we clarify and amend some confounding arguments and statements in the literature of the subject.Comment: 13 page

    On the Sequence of Pedal Triangles

    Get PDF
    Although geometers have studied the properties of triangles for over two thousand years, there still remain problems of interest involving operations performed infinitely often. A given triangle T_0 generates a sequence of triangles T_n where T_(n+1) is the pedal triangle of T_n. This sequence was discussed by Hobson (1897, 1925) but, while his formulae for the transition from T_n to T_(n+1) are correct, those for T_n in terms of T_0 are not. Lacking correct formulae, we experimented numerically, taking the angles of T_0 to be integers in degrees. To our surprise the angles in the pedal sequence became periodic with periods of 12 steps. The explanation of this curious fact led to a general investigation of pedal sequences, revealing that (a) the sequence may stop by degeneration of the triangle to a straight segment, (b) the angles may develop any periodicity, or (c) the sequence may proceed to infinity without any periodicity. We give necessary and sufficient conditions on the angles of T_0 corresponding to these options, and discuss the periodic case in some detail
