    Earnings of Black and White Youth and Their Relation to Poverty

    This paper examines the relation between youth employment and poverty for black and white families. An increase in the employment proportions of black men ages 16–19, which have lagged far behind their white counterparts, would reduce poverty among blacks to a moderate but meaningful degree. We provide evidence of a small positive feedback relation between black youth employment and family incomes that would magnify gains in both variables if either variable were increased. We also provide evidence that improvements in labor market conditions that affect youth employment, in the educational attainments of black youth, and in other policy-related variables would raise both youth employment and their family incomes.

    Quantum Logic and the Histories Approach to Quantum Theory

    Full text link
    An extended analysis is made of the Gell-Mann and Hartle axioms for a generalised `histories' approach to quantum theory. Emphasis is placed on finding equivalents of the lattice structure that is employed in standard quantum logic. Particular attention is given to `quasi-temporal' theories in which the notion of time-evolution is less rigid than in conventional Hamiltonian physics; theories of this type are expected to arise naturally in the context of quantum gravity and quantum field theory in a curved space-time. The quasi-temporal structure is coded in a partial semi-group of `temporal supports' that underpins the lattice of history propositions. Non-trivial examples include quantum field theory on a non globally-hyperbolic spacetime, and a simple cobordism approach to a theory of quantum topology. It is shown how the set of history propositions in standard quantum theory can be realised in such a way that each history proposition is represented by a genuine projection operator. This provides valuable insight into the possible lattice structure in general history theories, and also provides a number of potential models for theories of this type.Comment: TP/92-93/39 36 pages + one page of diagrams (I could email Apple laser printer postscript file for anyone who is especially keen

    Don’t Give Up Section 101, Don’t Ever Give Up

    In an era of tremendous and rapid technological advancement, coupled with the massive influence patents have on the global economy, determining the specific categories of inventions eligible for patent protection is of great importance. The statute governing patent eligible subject matter, 35 U.S.C. § 101, has unfortunately fallen steadily into a morass, wherein a great number of judicial philosophies as to the proper role and scope of § 101 occupy the statutes jurisprudence. This frustrates the utilitarian purpose of the patent system as research companies are uncertain whether certain categories of inventions will maintain their eligibly for patent protection. Because § 101 jurisprudence has fallen into chaos a natural reaction is to avoid the statute. This article explores how two competing theories of § 101 have emerged: the functional philosophy and the jurisdictional philosophy. This Comment argues that the proper role of § 101 is that of threshold inquiry, in line with the jurisdictional viewpoint under a legal and policy rationale. Calls to remove § 101 altogether overlook the important role the statute plays. It is an important safety net for the public—serving as a moral gatekeeper covering patents that pass muster under the other patentability requirements, but still represent a moral and utilitarian conundrum

    THE IMPACT OF INTERACTIVE FUNCTIONALITY ON LEARNING OUTCOMES: AN APPLICATION OF OUTCOME INTERACTIVITY THEORY

    Get PDF
    Scholars have examined a variety of dimensions and models of interactivity in an attempt to articulate a comprehensive definition. Outcome Interactivity Theory (OIT) considers interactivity to be the result of a communication event involving the successful integration of three predictive dimensions: the presence of actual interactive technological features, the presence of similarly reactive content elements, and relevant user experiences that empower the user to employ these interactive elements within the communication event toward a desirable outcome. This dissertation accomplishes three major objectives: clarify the literature relating to the interactivity construct; introduce Outcome Interactivity Theory as a new theory-based conceptualization of the interactivity construct; and test Outcome Interactivity Theory using a pre-test post-test control group full experimental design. The study tests the impact of interactivity on knowledge acquisition and satisfaction student learning outcomes. In addition, the OIT model itself is tested to measure the effect of interactivity on knowledge acquisition and satisfaction. Finally, this study presents a new set of highly reliable interactivity measurement scales to quantify the influence of specific individual dimensions and elements on interactivity as defined by the OIT model. Results are described, and limitations and practical implications are discussed

    Alternative Forum: A Colorado Farmer and the ITC’s Excellent Adventure

    Get PDF
    As marijuana regulation at the local level becomes at odds with federal policy, an interesting question arises regarding the drug’s potential classification as an article of commerce. Resulting of this potential shift is the existence of an unexpected legal question as to whether the U.S. International Trade Commission, via the agency’s section 337 investigatory and remedial authorities, may regulate marijuana that has been illegally imported into the United States. While avoiding any stance on the contentious issue of marijuana legalization, this essay explores this legal ramification by surmising a fictional narrative of two Colorado marijuana farmers, and investigating the ITC’s unique justiciability requirements and beneficial procedures. Difficult public policy considerations remain, but if employed, the section 337 could serve as a powerful tool for individuals to advance the U.S. interest of eradicating marijuana imported into the United States
