Philosophical Agents, John R. Rose, Michael N. Huhns Jan 2001

Philosophical Agents, John R. Rose, Michael N. Huhns

Faculty Publications

Abstraction is the technique we use to deal with complexity. What is the proper kind and level of abstraction for complex software agents? We think it would be reasonable to endow agents with a philosophy. Then, by understanding their philosophies, we can use them more effectively. To endow agents with ethical principles, developers need an architecture that supports explicit goals, principles and capabilities, as well as laws and ways to sanction or punish miscreants. All of the ethical approaches described in this article are single-agent in orientation and encode other agents implicitly.

Inside An Agent, José M. Vidal, Paul A. Buhler, Michael N. Huhns Jan 2001

Inside An Agent, José M. Vidal, Paul A. Buhler, Michael N. Huhns

Faculty Publications

When we discuss agent-based system construction with software developers or ask students to implement common agent architectures using object-oriented techniques, we find that it is not trivial for them to create an elegant system design from the standard presentation of these architectures in textbooks or research papers. To better communicate our interpretation of popular agent architectures, we draw UML (Unified Modeling Language) diagrams to guide an implementer's design. However, before we describe these diagrams, we need to review some basic features of agents. The paper considers an architecture showing a simple agent interacting with an environment. The agent senses its …

Good Day Sunshine: Stock Returns And The Weather, David Hirshleifer, Tyler Shumway Jan 2001

Good Day Sunshine: Stock Returns And The Weather, David Hirshleifer, Tyler Shumway

Faculty Publications

Psychological evidence and casual intuition predict that sunny weather is associated with upbeat mood. This paper examines the relationship between morning sunshine in the city of a country's leading stock exchange and daily market index returns across 26 countries from 1982 to 1997. Sunshine is strongly significantly correlated with stock returns. After controlling for sunshine, rain and snow are unrelated to returns. Substantial use of weatherbased strategies was optimal for a trader with very low transactions costs. However, because these strategies involve frequent trades, fairly modest costs eliminate the gains. These findings are difficult to reconcile with fully rational price …

Surface Analogy And Spelling Rules In English Vowel Alterations, David Eddington Jan 2001

Surface Analogy And Spelling Rules In English Vowel Alterations, David Eddington

Faculty Publications

Previous psycholinguistic research into the English vocalic system suggest that the vowel alternations [ei-re, ii-£, ai-1, ow- a, u"-A], termed SPELLING RULE ALTERNATIONS, are psychologically significant for English speakers, in that they can influence the pronunciation of unfamiliar words. In this paper, the influence of these salient alternations on nonce words and neologisms is assessed. The effect of su1face analogy on the pronunciation of novel words is also examined. Surface analogy may be defined as the influence exerted by the fu lly specified surface forms of the morphemic relatives of a word. It assumes that all allomorphs of a given …

The Bullet Gic As An Example, David F. Babbel, Jeremy Gold, Craig B. Merrill Jan 2001

The Bullet Gic As An Example, David F. Babbel, Jeremy Gold, Craig B. Merrill

Faculty Publications

There has been considerable discussion of a variety of issues related to fair value in the actuarial literature, in conferences, and among individuals interested in this topic. Unfortunately, we seem to be failing to communicate due, in part, to inconsistent use of terminology. The goal of this discussion paper is to present a few concepts that we hope will be of use in the broader discussion of fair value of liabilities.

An Operator-Based Account Of Semantic Processing, Deryle W. Lonsdale, C. Anton Rytting Jan 2001

An Operator-Based Account Of Semantic Processing, Deryle W. Lonsdale, C. Anton Rytting

Faculty Publications

This paper explores issues of psychological plausibility in modeling natural language understanding within Soar, a symbolic cognitive model. It focuses on constructing syntactic and semantic representations in simulated real time, with particular emphasis on word sense disambiguation (WSD). We discuss (i) what level of WSD should be modeled and (ii) how to use resources such as WordNet to inform these models. A preliminary model of coarse-grained WSD is included to show how syntactic, semantic, and other knowledge sources interact in Soar. Finally, we explore issues of interleaving, learning, and integrating other WSD approaches with Soar's native model of learning.

All That Glitters Is Not Gold: Bad Forgiveness In Counseling And Preaching, John M. Berecz Jan 2001

All That Glitters Is Not Gold: Bad Forgiveness In Counseling And Preaching, John M. Berecz

Faculty Publications

A 3 R's of Forgiveness model is presented in which forgiveness is seen as a complex therapeutic process involving both situational and personal variables. Forgivers are seen to utilize the cognitive processes of dialectical reasoning and reframing, modulated by the emotional experiences of empathy, guilt, and shame. Personality style and self-esteem significantly influence the process as well. Distinctions are maintained among various kinds of forgiveness. Divine forgiveness, seen as a partial component of a spiritual encounter with one's God, may be a valid experience for people of faith, but is not something that psychologists are equipped to experimentally analyze. Interpersonal …

Faculty Publications

The unoccupied electronic structure for the Sr14Cu24O41 family of two-leg ladder compounds was investigated for different partial substitutions of Sr2+ by Ca2+, leaving the nominal hole count constant, and by Y3+ or La3+, reducing the nominal hole count from its full value of 6 per formula unit. Using polarization-dependent x-ray absorption spectroscopy on single crystals, hole states on both the chain and ladder sites could be studied. While for intermediate hole counts all holes reside on O sites of the chains, a partial hole occupation on the ladder sites in orbitals oriented along the legs is observed for the fully …

Proteolytic Enzymes In The Marine Bacterium Pseudoalteromonas Atlantica: Post-Secretional Activation And Effects Of Environmental Conditions, Monica Hoffman, Alan W. Decho Dec 2000

Proteolytic Enzymes In The Marine Bacterium Pseudoalteromonas Atlantica: Post-Secretional Activation And Effects Of Environmental Conditions, Monica Hoffman, Alan W. Decho

Faculty Publications

Production and activities of cellular and extracellular proteolytic enzymes associated with the marine bacterium Pseudoalteromonas atlantica were examined in response to physiological state and changing environmental variables under laboratory conditions. Enzymes evidenced by zymography were metalloproteases, as defined by substrate preference and susceptibility to inhibitors (EDTA and 1, 10-phenanthroline). Distinct bands (i.e. molecular-weight [MW] size classes) of enzymes were isolated from within cellular and extracellular compartments. Susceptibility of extracellular enzymes to environmental stressors was related, in part, to the MW size classes of the enzymes. While all bands of enzymes showed some degree of inhibition when pH was decreased, the …

Kinetic Characterization Of His-Tagged Cp47 Photosystem Ii In Synechocystis Sp. Pcc6803, Zhao Liang Li, Terry M. Bricker, Robert Burnap

Faculty Publications

Recently, construction of strains of Synechocystis sp. PCC6803 having a His6 extension (His-tag) of the carboxyl terminus of the CP47 protein has been reported (T.M. Bricker et al, Biochim. Biophys. Acta 1409 (1998) 50; M.J. Reifler et al., in: Garab, Pusztai (Eds.) Proc. XIth International Congress on Photosynthesis, 1998). While these initial reports suggest a minimal impact of the His-tag upon Photosystem (PS) II function, a more thorough analysis of the kinetic properties of the modified complex is essential. This communication reports on a more detailed kinetic analysis to assess possible perturbations of PS II due to the genetic addition …

Dna Binding Properties Of The Arabidopsis Floral Development Protein Aintegumenta, Staci Nole-Wilson, Beth A. Krizek Nov 2000

Dna Binding Properties Of The Arabidopsis Floral Development Protein Aintegumenta, Staci Nole-Wilson, Beth A. Krizek

Faculty Publications

The Arabidopsis protein AINTEGUMENTA (ANT) is a member of a plant-specific family of transcription factors (AP2/EREBP) that share either one or two copies of an approximately 70 amino acid region called the AP2 repeat. DNA binding activity has been demonstrated previously for members of this family containing a single AP2 repeat. Using an in vitro selection procedure, the DNA binding specificity of the two AP2 repeat containing protein ANT was found to be 5'-gCAC(A/G)N(A/T)TcCC(a/g)ANG(c/t)-3'. This consensus site is much longer than sites recognized by proteins containing a single AP2 repeat and neither AP2 repeat of ANT was alone capable of …

Toward Automated Abstraction For Protocols On Branching Networks, Michael D. Jones, Ganesh Gopalakrishnan Nov 2000

Toward Automated Abstraction For Protocols On Branching Networks, Michael D. Jones, Ganesh Gopalakrishnan

Faculty Publications

We have used various manual abstraction techniques to formally verify a transaction ordering property for an IO protocol over bus/bridge networks. In the context of network protocol verification, an abstraction is needed to reduce the unbounded number of network configurations to a small number of representative networks that can be checked using algorithmic methods. The manually derived abstraction was both brittle and difficult to validate. In this report, we discuss the need for abstraction techniques in the formal verification of protocols over networks and present our recent efforts to create an automatic abstraction technique for network protocols using predicate abstraction …

Emotion And Group Cohesion In Productive Exchange, Edward J. Lawler, Shane R. Thye, Jeongkoo Yoon Nov 2000

Emotion And Group Cohesion In Productive Exchange, Edward J. Lawler, Shane R. Thye, Jeongkoo Yoon

Faculty Publications

This study refines and experimentally tests a theory of relational cohesion that explains how and when actors become committed to one another in the context of multiactor exchange. The theory asserts that frequent social exchange results in (1) positive emotions that solidify and strengthen the person-to-group bond and (2) uncertainty reduction that renders the focal group more salient in relation to others. These two mechanisms produce a sense of psychological group formation and ultimately increase observable acts of commitment. In a “productive exchange” setting, three actors negotiate a joint venture that requires the assent of all members. The exchanges featured …

System Level Microwave Design: Radar-Based Laboratory Projects, Michael A. Jensen, David V. Arnold, Donald E. Crockett Nov 2000

System Level Microwave Design: Radar-Based Laboratory Projects, Michael A. Jensen, David V. Arnold, Donald E. Crockett

Faculty Publications

Two laboratory projects-a Doppler radar and a synthetic aperture radar (SAR)-designed to augment traditional electromagnetics education are proposed. The projects introduce students to component and system level design and expose them to modern computer-aided design (CAD) tools, microstrip and surface mount fabrication technologies, and industry standard test equipment and procedures. Additionally, because the projects result in a working radar system, students gain new enthusiasm for the electromagnetics discipline and directly see its relevance in the engineering field. Implementation of these laboratories within the curriculum have proven to be highly motivational and educational and have even contributed to increased enrolments in …

Nonsteroidal Anti-Inflammatory Drugs, Acetaminophen, Cyclooxygenase 2, And Fever, Daniel L. Simmons, David Wagner, Kenneth Westover Oct 2000

Nonsteroidal Anti-Inflammatory Drugs, Acetaminophen, Cyclooxygenase 2, And Fever, Daniel L. Simmons, David Wagner, Kenneth Westover

Faculty Publications

Nonsteroidal anti-inflammatory drugs (NSAIDs) are frequently used antipyretic agents that most probably exert their antifever effect by inhibiting cyclooxygenase (COX)–2. Thus, COX-2–selective drugs or null mutation of the COX-2 gene reduce or prevent fever. Acetaminophen is antipyretic and analgesic, as are NSAIDs, but it lacks the anti-inflammatory and anticoagulatory properties of these drugs. This has led to the speculation that a COX variant exists that is inhibitable by acetaminophen. An acetaminophen-inhibitable enzyme is inducible in the mouse J774.2 monocyte cell line. Induction of acetaminophen-inhibitable prostaglandin E2 synthesis parallels induction of COX-2. Thus, inhibition of pharmacologically distinct COX-2 enzyme activity by …

A Form Letter From The Dean, R. Lawrence Dessem Oct 2000

A Form Letter From The Dean, R. Lawrence Dessem

Faculty Publications

A few years ago, in “A Form Letter to the Dean,” I offered the Journal's readers a template form letter which law school faculty could use to communicate with their deans. In the aftermath of that article's publication, I received letters, phone calls, and small explosive devices indicating that, mirabile dictu, a few people had actually read the article. Because I had never before had such a response to any of what I rather loosely refer to as my scholarship, I was encouraged to write a sequel. Hence the present piece. My current form letter is inspired by the annual …

Bringing Structure To The Law Of Injunctions Against Expression, Christina E. Wells Oct 2000

Bringing Structure To The Law Of Injunctions Against Expression, Christina E. Wells

Faculty Publications

Part I of this Article reviews the Court's cases regarding injunctions against speech, focusing first on the increasing elevation of rhetoric (as opposed to analysis) in the Court's prior restraint decisions. Part I also reviews the Court's other decisions involving injunctions and demonstrates that they too contain little, if any, analysis concerning the appropriateness of injunctive relief against expression. Part II examines Madsen's interaction with the Court's previous decisions and discusses how Madsen furthers the incoherence of the Court's previous cases. Part III explains that content discrimination principles, although superficially attractive, are inappropriate with injunctive relief because the content-based/content-neutral distinction's …
