Pharmacologic Treatments of Cocaine Dependence

The rapid escalation of cocaine abuse in the United States in the 1980\u27s has generated a host of interesting hypotheses on various aspects of this problem. After a succinct discussion of epidemiologic, clinical, and neuro-pharmacologic aspects of cocaine abuse, a survey of the current literature on psychopharmacologic management of dependence is offered. While several agents have emerged as useful adjunctive treatments for abstinence syndromes it is important for the clinician to remember that there is not official approval for such treatments. Additionally, psychotherapeutic maneuvers, which remain the major tools in treatment of addicts, should not be overlooked when an experimental pharmacologic intervention is selected

Mixture modeling with applications in schizophrenia research

Finite mixture modeling, together with the EM algorithm, have been widely used in clustering analysis. Under such methods, the unknown group membership is usually treated as missing data. When the "complete data" (log-)likelihood function does not have an explicit solution, the simplicity of the EM algorithm breaks down. Authors, including Rai and Matthews (1993), Lange (1995a) and Titterington (1984), developed modified algorithms therefore. As motivated by research in a large neurobiological project, we propose in this paper a new variant of such modifications and show that it is self-consistent. Moreover, simulations are conducted to demonstrate that the new variant converges faster than its predecessors.

Symphony No. 2 The Great Expanse

Symphony No. 2 “The Great Expanse†is a 20-minute composition commissioned by the California Youth Symphony in 2016. The title of the work serves as a reference to its: 1) initial musical inspiration -- drawing on expanding and contracting interval sets; 2) construction of these sets around the expanse of the composer’s instrument, the piano; 3) metaphorical place in the composer’s ouvre – that this second symphony is an expansion of the composer’s abilities since his first symphony as a Bachelor’s student; and 4) programmatic elements dealing with the expanse of time, space and the unknown. The construction of this piece deals with many pre-compositional techniques, all of which aim to relate elements of pitch, rhythm, phrasing, and form simultaneously to the concepts of expansion and contraction. The result of that preplanning manifested itself in a two movement work (I. …of dark; and II. …of light), which is highly structured and deeply personal to the composer. | 72 page

The Role of Efficiencies in Telecommunications Merger Review

As a result of the recent telecommunications industry slowdown and the rise of globally integrated communications networks, mergers and acquisitions have become a commonplace occurrence throughout the developed world. In this article, Calvin Goldman, Michael Piaskoski and Ilene Gotts review recent merger and acquisition activity and discuss how the decisions to allow or deny “M&A” are viewed by regulatory agencies in the United States, the European Union, and Canada. The first part of this article addresses these three parties’ approaches to M&A consideration and how the concept of “efficiencies” generated by consolidation enters those deliberations. The authors then explore the finer points of “competition review” in the United States, European Union, and Canada and then discuss the individual propensities of these three regulators to consider the proposed efficiencies of telecommunications mergers and acquisitions. The authors conclude that while Canada has been increasingly deferential to proposed efficiencies, and the United States and especially the European Union have remained somewhat reluctant to consider efficiencies arguments, that understanding the complexities of efficiencies review is increasingly critical in the developed world

On group strategy-proof mechanisms for a many-to-one matching model

For the many-to-one matching model in which firms have substitutable and quota q-separable preferences over subsets of workers we show that the workers-optimal stable mechanism is group strategy-proof for the workers. In order to prove this result, we also show that under this domain of preferences (which contains the domain of responsive preferences of the college admissions problem) the workers-optimal stable matching is weakly Pareto optimal for the workers and the Blocking Lemma holds as well. We exhibit an example showing that none of these three results remain true if the preferences of firms are substitutable but not quota q-separable.The work of R. Martínez, A. Neme, and J.
