The Impact Of Regulation Fair Disclosure On Information Asymmetry And Trading: An Intraday Analysis, Chiraphol N. Chiyachantana, Christine X. Jiang, Nareerat Taechapiroontong, Robert A. Wood

Research Collection Lee Kong Chian School Of Business

This study examines the impact of Regulation Fair Disclosure (FD) on liquidity, information asymmetry, and institutional and retail investors trading behavior. Our main findings suggest three conclusions. First, Regulation FD has been effective in improving liquidity and in decreasing the level of information asymmetry. Second, retail trading activity increases dramatically after earnings announcements but there is a significant decline in institutional trading surrounding earnings announcements, particularly in the pre‐announcement period. Last, the decline in information asymmetry around earnings announcements is closely associated with a lower participation rate in the pre‐announcement period and more active trading of retail investors after earnings …

Creating A Distributed Field Robot Architecture For Multiple Robots, Matthew T. Long

USF Tampa Graduate Theses and Dissertations

This thesis describes the design and implementation of a distributed robot architecture, Distributed Field Robot Architecture. The approach taken in this thesis is threefold. First, the distributed architecture builds on existing hybrid deliberative/reactive architectures used for individual robots rather than creating a distributed architecture that requires re-engineering of existing robots. Second, the distributed layer of the architecture incorporates concepts from artificial intelligence and software agents. Third, the architecture is designed around Suns Jini middleware layer, rather than creating a middleware layer from scratch or attempting to adapt a software agent architecture. This thesis makes three primary contributions, both theoretical and …

The Mormon Hive: A Study Of The Bee And Beehive Symbols In Nineteenth Century Mormon Culture, J. Michael Hunter

Faculty Publications

From antiquity to the middle of the eighteenth century, humans used the bee and beehive symbols to represent monarchy. Political and social changes resulted in a reinterpretation of the bee and beehive symbols during the eighteenth century. Republicans ignored the royalist associations of bees and beehives, and used them to represent values of the new republicanism. In nineteenth-century America, the Mormons, members of The Church of Jesus Christ of Latter-day Saints, encountered the bee and beehive symbols while participating in the rites of Freemasonry. In the nineteenth century, Mormons used the bee and beehive symbols to represent the Kingdom of …

How Cellular Movement Determines The Collective Force Generated By The Dictyostelium Discoideum Slug, J. C. Dallon, H. G. Othmer

Faculty Publications

How the collective motion of cells in a biological tissue originates in the behavior of a collection of individuals, each of which responds to the chemical and mechanical signals it receives from neighbors, is still poorly understood. Here we study this question for a particular system, the slug stage of the cellular slime mold Dictyostelium discoideum. We investigate how cells in the interior of a migrating slug can effectively transmit stress to the substrate and thereby contribute to the overall motive force. Theoretical analysis suggests necessary conditions on the behavior of individual cells, and computational results shed light on experimental …

Faculty Publications

Islamic, Hindu, Buddhist, Baha'i, Jewish, and Christian organizations are all experimenting with distance education for various reasons and to different extents, due to religious, economic, and political factors. Religious institutions worldwide are not only turning to the World Wide Web (WWW) to place information concerning religious beliefs and provide virtual services for their constituents but are also getting more involved in formally educating their members at a distance. This paper will document some of these educational efforts and the reasons behind the expanding use of distance education by several of the major religious institutions for training, edifying, and educating their …

A Review Of Antennas And Propagation For Mimo Wireless Communications, Michael A. Jensen, Jon W. Wallace

Faculty Publications

Multiple-input-multiple-output (MIMO) wireless systems use multiple antenna elements at transmit and receive to offer improved capacity over single antenna topologies in multipath channels. In such systems, the antenna properties as well as the multipath channel characteristics play a key role in determining communication performance. This paper reviews recent research findings concerning antennas and propagation in MIMO systems. Issues considered include channel capacity computation, channel measurement and modeling approaches, and the impact of antenna element properties and array configuration on system performance. Throughout the discussion, outstanding research questions in these areas are highlighted.

Optimization Of Batch Reactions In Series With Uncertainty, Keith G. Tomazi

Chemical and Biochemical Engineering Faculty Research & Creative Works

Certain types of chemical reactions, such as the global deprotection of a polypeptide, are extremely complex. As a result, it may be very difficult or expensive to develop accurate models of these chemical reactions. Without a satisfactory kinetic model for the reaction, it is difficult to develop an optimum operating policy that will maximize the profit. Stochastic optimization is applied in this work to an example process step to obtain the optimum reaction temperature and reaction time. In the case of the "here and now" problem, the optimal conditions are a lower reaction temperature and a longer reaction time than …

Transport Of The Harmful Bloom Alga Aureococcus Anophagefferens By Oceangoing Ships And Coastal Boats, Martina A. Doblin, Linda C. Popels, Kathryn J. Coyne, David A. Hutchins, S. Craig Cary, Fred C. Dobbs

OES Faculty Publications

It is well established that cyst-forming phytoplankton species are transported in ships' ballast tanks. However, there is increasing evidence that other phytoplankton species which do not encyst are also capable of surviving ballast transit. These species have alternative modes of nutrition (hetero- or mixotrophy) and/or are able to survive long-term darkness. In our studies of no-ballast-on-board vessels arriving in the Great Lakes, we tested for the presence of the harmful algal bloom species Aureococcus anophagefferens (brown tide) in residual (i.e., unpumpable) ballast water using methods based on the PCR. During 2001, the brown tide organism was detected in 7 of …

Singapore: Always Restructuring, Avoiding Convergence And Reining In Divergence, Tan K. B. Eugene

Research Collection Yong Pung How School Of Law

Even as the government declares Asia - with China and India at the forefront - as a region of change and opportunities, the fear of becoming irrelevant ensures that Singapore will not relent in its drive to stay ahead of the regional economic competition. For instance, the search for new industrial winners, after the successful industrial programmes in electronics and the biomedical sciences, has begun resolutely with the formation of a high-powered ministerial committee to mould Singapore's research and development destiny. Restructuring in Singapore is a governing norm that is very much invoked as a policy necessity and a way …

The Changing Political Economy Of Party Membership, Riccardo Pelizzo

Research Collection School of Social Sciences

Although few scholars would dispute from an empirical point of view the fact that parties change their electoral strategies, ideological stances and organizational structures over time, there is not much agreement on how these changes, above all party organizational change, have to be understood from a theoretical point of view. This is especially true with regard to the transformations that party organizations have undergone from the early 1970s on. In fact, although party organizational changes in the past three decades have generally been considered to be signs of the so called party crisis, the agreement on this analytical perspective is …

Recollections Of The 1952 International North Pacific Fisheries Convention: The Decline Of The Principle Of Abstention, Shigeru Oda

San Diego International Law Journal

Having recently completed twenty-seven years on the bench of the International Court of Justice in The Hague, I have just returned to Sendai, Japan, my home town. Please permit me therefore to offer some personal recollections of the time fifty years ago when, as a graduate law student from occupied Japan traveling on a passport issued by General MacArthur, Supreme Commander of the Allied Powers in Japan, I began preparation of my doctoral dissertation at Yale Law School.

Japan, The North Atlantic Triangle, And The Pacific Fisheries: A Perspective On The Origins Of Modern Ocean Law, 1930-1953, Harry N. Scheiber

San Diego International Law Journal

I seek to establish here the degree to which multilateralism prevailed in the postwar era, or instead was overcome by unilateralist objectives and methods in pursuit of national interests. The empirical basis and special focus in much of my analysis is the discussion of Canada's role in regard to the diplomacy of the Pacific fisheries and more generally in regard to the process of developing modern ocean law as reflected in Canadian-U.S.-Japanese-British relations.

Two-Loop Bethe Logarithms For Higher Excited S Levels, Ulrich D. Jentschura

Physics Faculty Research & Creative Works

Processes mediated by two virtual low-energy photons contribute quite significantly to the energy of hydrogenic S states. The corresponding level shift is of the order of ( α / π )² ( Z α )⁶ m_ec² and may be ascribed to a two-loop generalization of the Bethe logarithm. For 1 S and 2 S states, the correction has recently been evaluated by Pachucki and Jentschura [Phys. Rev. Lett. 91, 113005 (2003)]. Here, we generalize the approach to higher excited S states, which in contrast to the 1 S and 2 S states can decay to …

The Republican Model And Punitive Damages, David F. Partlett

San Diego Law Review

Fueled by complaints of outlandish punitive damage awards and a United States Supreme Court intent on bringing constitutional order to this corner of torts damages, a considerable literation has emerged. Commentators have examined the bases for the award of punitive damages and have applied empirical analysis to probe the legitimacy of popular criticism and the extent to which punitive damages fulfill the goals assigned to them. In this essay, I propose that punitive damages should be conceptualized in light of a republican theory of tort law with the jury as its central institution. This is ironic, since influential commentators and …

Prometheus Bound Or Loose Cannon? Punitive Damages For Pure Breach Of Contract In Canada, John D. Mccamus

San Diego Law Review

This Article examines the Supreme Court of Canada's punitive damage awards in pure breach of contract cases in recent years. The Supreme Court reaffirmed this development in its recent and leading decision in Whiten v. Pilot Insurance Co. The Court attempted to craft an approach to the awarding of punitive damages that would avoid the worst excesses of the American experience in Pilot Insurance. The author explores whether the Court succeeded in attaining that laudable objective, concluding that the decision disappoints by failing to supply a convincing reason for extending the scope of punitive damages in the contract context beyond …

Reconceptualizing Aggravated Damages: Recognizing The Dignitary Interest And Referential Loss, Jeffry Berryman

San Diego Law Review

In this Article, the author argues for the explicit recognition of the "dignitary interest" as a distinct head of damages. In Part I, he analyzes recent decisions of the Supreme Court of Canada that have commented on the availability of aggravated damages. Part II identifies how the protection of dignity lies at the root of awards for aggravated damages. Part III conceptualizes what is encompassed within the "dignitary interest." Part IV contrasts a purely remedial response with those who advocate a new tort action to protect loss of dignity. Finally, the prescriptive power of explicit recognition of the dignitary interest …

Brown Ii's "All Deliberate Speed" At Fifty: A Golden Anniversary Or A Mid-Life Crisis For The Constitutional Injunction As A School Desegregation Remedy?, Doug Rendleman

San Diego Law Review

In 1955 in Brown II the Supreme Court instructed school authorities and federal judges how to implement its decision in Brown I that racially segregated public schools violated the constitution. This article summarizes the half-century of federal injunctions that the courts granted to desegregate schools. It organizes the injunctions chronologically under three headings, "all deliberate speed," desegregate "now," and "unitary" districts. Rejecting both extravagant hoopla and charges of "failure," the article approves disciplined judicial discretion leading to large-scale structural injunctions when the times are ripe because unconstitutional conditions warrant massive judicial reconstruction. In particular, the article maintains that the courts' …

Nucleation Rates Of Water And Heavy Water Using Equations Of State, Abdalla Obeidat, Jin-Song Li, Gerald Wilemski

Physics Faculty Research & Creative Works

The original formula of Gibbs for the reversible work of critical nucleus formation is evaluated in three approximate ways for ordinary and heavy water. The least approximate way employs an equation of state to evaluate the pressure difference between the new and old phases. This form of the theory yields a temperature dependence for the nucleation rate close to that observed experimentally. This is a substantial improvement over the most commonly used (and most approximate) form of classical theory.©2004 American Institute of Physics.
