Applying Information Technology to Financial Statement Analysis for Market Capitalization Prediction  [PDF]
Hayden Wimmer, Roy Rada
Open Journal of Accounting (OJAcct) , 2013, DOI: 10.4236/ojacct.2013.21001
Abstract: Determining which attributes may be employed for predicting the market capitalization of a business firm is a challenging task which may benefit from research intersecting principles of accounting and finance with information technology. In our approach, information technology in the form of decision trees and genetic algorithms is applied to fundamental financial statement data in order to support the decision making process for predicting the direction of the value of a company with value defined as the market capitalization. The decision process differs from year to year; however, the amount of variation is crucial to a successful decision making process. The research question posed is “how much variation occurs between years?” We hypothesize the amount of variation is smaller than half the number of financial statement attributes that may be employed in the decision making process. We develop a system which tests the amount of variation between years measured as the amount of generations required to reach a target level of fitness. The hypothesis is tested using data filtered from Compustat’s global database. The results support the research hypothesis and advance us toward answering the research question. The implications of this research are the possibility to improve the decision process when employing financial statement analysis as applied to the market capitalization and financial valuation of business firms.
Sem patente n?o há genérico: acesso farmacêutico e políticas de cópia
Hayden, Cori;
Sociologias , 2008, DOI: 10.1590/S1517-45222008000100005
Abstract: drawing on ethnographic research in mexico and argentina, this essay addresses the promise, limits, and specificities of the generic pharmaceutical as a legal, technical, and political artifact. attending to the complex commercial semiotics of "similarity" in mexico, and to the powerful figure of the domestic copia in argentina, i argue that at stake with the rise and expansion of markets for generic drugs is not simply a david and goliath relationship between the (cheaper, accessible, democratizing) generic and the (expensive) patented original. also central to a politics of the generic is the shifting line between the licit and the illicit copy. the essay thus poses the question, what are the implications of configuring a political language of "access" around the terms of intellectual property itself?

The Residential Demand for Electricity in the United States
Hayden Neeland
Economic Analysis and Policy , 2009,
Abstract: This paper analyses historical data of residential electricity demand in the United States for the period 1970-2007. Such analysis is conducted through an ADF unit root test, Johansen test and a rolling regression. The results indicate that the primary driver of adjustments in electricity consumption is the own price elasticity of demand and growth in real income per capita.
Islet Amyloid, Metabolic Syndrome, and the Natural Progressive History of Type 2 Diabetes Mellitus
Hayden MR
JOP Journal of the Pancreas , 2002,
Abstract: The presence of amyloid within the islet of the pancreas may be one of the best kept secrets in clinical medicine and translation of this century old finding may help to better understand the progressive nature of type 2 diabetes mellitus. Insulin resistance, metabolic syndrome, and type 2 diabetes mellitus are associated with multiple metabolic toxicities which result in an elevated tension of redox stress within the islet. Redox stress is associated with damage to proteins, lipids, and nucleic acids which may have a profound affect upon the structure and function of the islet. Earlier diagnosis at the stage of impaired glucose tolerance (prediabetes) and intervention may have a positive outcome on stabilization of the vulnerable islet and beta cell as well as the multiple diabetic complications. The natural history and a shift in the treatment paradigm of type 2 diabetes mellitus is explored as a result of these century old findings.
A Search for Heavy Resonances in the Dilepton Channel
Hayden Daniel
EPJ Web of Conferences , 2012, DOI: 10.1051/epjconf/20122812003
Abstract: There are many extensions to the Standard Model of particle physics which predict the addition of a U(1) symmetry, and/or extra spatial dimensions, which give rise to new high mass resonances such as the Z′ and Randall-Sundrum graviton. The LHC provides a unique opportunity to explore the TeV scale where these phenomena may become apparent, and can be searched for using the precision tracking and high energy resolution calorimetry of the ATLAS detector. This poster presents the search for high mass resonances in the dilepton channel, and was conducted with an integrated luminosity of 1.08/1.21 fb 1 in the dielectron/dimuon channel respectively, at a centre of mass energy √s = 7 TeV.
