Genetic Evidence For The Proto-Austronesian Homeland In Asia: Mtdna And Nuclear Dna Variation In Taiwanese Aboriginal Tribes, Terry Melton, Stephanie Clifford, Jeremy Martinson, Mark Batzer, Mark Stoneking Jan 1998

Genetic Evidence For The Proto-Austronesian Homeland In Asia: Mtdna And Nuclear Dna Variation In Taiwanese Aboriginal Tribes, Terry Melton, Stephanie Clifford, Jeremy Martinson, Mark Batzer, Mark Stoneking

Faculty Publications

Previous studies of mtDNA variation in indigenous Taiwanese populations have suggested that they held an ancestral position in the spread of mtDNAs throughout Southeast Asia and Oceania (Melton et al. 1995; Sykes et al. 1995), but the question of an absolute proto-Austronesian homeland remains. To search for Asian roots for indigenous Taiwanese populations, 28 mtDNAs representative of variation in four tribal groups (Ami, Atayal, Bunun, and Paiwan) were sequenced and were compared with each other and with mtDNAs from 25 other populations from Asia and Oceania. In addition, eight polymorphic Alu insertion loci were analyzed, to determine if the pattern …

On Summability Of Distributions And Spectral Geometry, R. Estrada, J. M. Gracia-Bondía, J. C. Várilly Jan 1998

On Summability Of Distributions And Spectral Geometry, R. Estrada, J. M. Gracia-Bondía, J. C. Várilly

Faculty Publications

Modulo the moment asymptotic expansion, the Cesàro and parametric behaviours of distributions at infinity are equivalent. On the strength of this result, we construct the asymptotic analysis for spectral densities arising from elliptic pseudodifferential operators. We show how Cesàro developments lead to efficient calculations of the expansion coefficients of counting number functionals and Green functions. The bosonic action functional proposed by Chamseddine and Connes can more generally be validated as a Cesàro asymptotic development.

Variations In The Secondary Metabolite Camptothecin In Relation To Tissue Age And Season In Camptotheca Acuminata, Zhijun Liu, Stanley B. Carpenter, Wayne J. Bourgeois, Ying Yu, Roysell J. Constantin, Matthew J. Falcon, John C. Adams Jan 1998

Variations In The Secondary Metabolite Camptothecin In Relation To Tissue Age And Season In Camptotheca Acuminata, Zhijun Liu, Stanley B. Carpenter, Wayne J. Bourgeois, Ying Yu, Roysell J. Constantin, Matthew J. Falcon, John C. Adams

Faculty Publications

We investigated variation in concentration of the secondary metabolite, camptothecin (CPT), in relation to leaf, branch and tree age, season, and leaf drying method in Camptotheca acuminata Decaisne saplings. Younger leaves contained higher CPT concentrations than older leaves. Within a branch, there was a linear decline in CPT concentration from leaves at the apex of the branch down to Leaf 7. Comparing leaves of similar age, those from younger trees had higher CPT concentrations than those from older trees. Over the course of the growing season, there was a steady decline of 11% per month in leaf CPT concentration. Branches …

Evidence In The Global Village: The Promise And Challenge Of Computer-Assisted Research In Intercollegiate Debate, Pat J. Gehrke Jan 1998

Evidence In The Global Village: The Promise And Challenge Of Computer-Assisted Research In Intercollegiate Debate, Pat J. Gehrke

Faculty Publications

The growing importance of research databases and the proliferation of evidence sources on the Internet have provoked responses from the debate community ranging from ecstatic hope to pronounced fear. The debate community should critically incorporate databases and the Internet into its research. The benefits of computer-assisted research are plentiful, if we can appropriately adjust as a community to the age of digitized research.

Evaluation Of The Acoustic Doppler Velocimeter (Adv) For Turbulence Measurements, George Voulgaris, John H. Trowbridge Jan 1998

Evaluation Of The Acoustic Doppler Velocimeter (Adv) For Turbulence Measurements, George Voulgaris, John H. Trowbridge

Faculty Publications

Accuracy of the acoustic Doppler velocimeter (ADV) is evaluated in this paper. Simultaneous measurements of open-channel flow were undertaken in a 17-m flume using an ADV and a laser Doppler velocimeter. Flow velocity records obtained by both instruments are used for estimating the true (‘‘ground truth’’) flow characteristics and the noise variances encountered during the experimental runs. The measured values are compared with estimates of the true flow characteristics and values of variance (^u92&, ^w92&) and covariance (^u9w9&) predicted by semiempirical models for open-channel flow. The analysis showed that the ADV sensor can measure mean velocity and Reynolds stress within …

Family Generativity And Generative Counseling: Helping Families Keep Faith With The Next Generation, David C. Dollahite, Brent D. Slife, Alan J. Hawkins Jan 1998

Family Generativity And Generative Counseling: Helping Families Keep Faith With The Next Generation, David C. Dollahite, Brent D. Slife, Alan J. Hawkins

Faculty Publications

Counselors who are concerned with strengthening and healing relationships between generations can draw on the concept of generativity to assist them. This chapter invites counselors to grant a more prominent place for generativity in clinical work with families by (a) presenting the concept of family generativity as a logical extension of the generativity concept and (b) presenting some initial ideas on the new approach to clinical work designed to help families develop and sustain family generativity, which we call generative counseling. Generative counseling is illustrated by use of a clinical example, which is introduced briefly in a subsequent section …

Intentional Changes In Sound Pressure Level And Rate: Their Impact On Measures Of Respiration, Phonation, And Articulation, Christopher Dromey, Lorraine Olson Ramig Jan 1998

Intentional Changes In Sound Pressure Level And Rate: Their Impact On Measures Of Respiration, Phonation, And Articulation, Christopher Dromey, Lorraine Olson Ramig

Faculty Publications

The purpose of the study was to compare the effects of changing sound pressure level (SPL) and rate on respiratory, phonatory, and articulatory behavior during sentence production. Ten subjects, 5 men and 5 women, repeated the sentence, "I sell a sapapple again," under 5 SPL and 5 rate conditions. From a multi-channel recording, measures were made of lung volume (LV), SPL, fundamental frequency (F0), semitone standard deviation (STSD), and upper and lower lip displacements and peak velocities. Loud speech led to increases in LV initiation, LV termination, F0, STSD, and articulatory displacements and peak velocities for both lips. Token-to-token variability …

Overt And Relational Aggression In Russian Nursery-School-Age Children: Parenting Style And Marital Linkages, Craig H. Hart, David A. Nelson, Clyde C. Robinson, Susanne Frost Olson, Mary Kay Mcneilly-Choque Jan 1998

Overt And Relational Aggression In Russian Nursery-School-Age Children: Parenting Style And Marital Linkages, Craig H. Hart, David A. Nelson, Clyde C. Robinson, Susanne Frost Olson, Mary Kay Mcneilly-Choque

Faculty Publications

Maternal and paternal parenting styles and marital interactions linked in childhood aggressive behavior as described in Western psychological literature were measured in an ethnic Russian sample of 207 families of nursery-school-age children. Results corroborated and extended findings from Western samples. Maternal and paternal coercion, lack of responsiveness, and psychological control (for mothers only) were significantly correlated with children's overt aggression with peers. Less responsiveness (for mothers and fathers) and maternal coercion positively correlated with relational aggression. Some of these associations differed for boys versus girls. Marital conflict was also linked to more overt and relational aggression for boys. When entered …

Implicit Feedback For Recommender Systems, Douglas W. Oard, Jinmook Kim Jan 1998

Implicit Feedback For Recommender Systems, Douglas W. Oard, Jinmook Kim

Faculty Publications

Can implicit feedback substitute for explicit ratings in recommender systems? If so, we could avoid the difficulties associated with gathering explicit ratings from users. How, then, can we capture useful information unobtrusively, and how might we use that information to make recommendations? In this paper we identify three types of implicit feedback and suggest two strategies for using implicit feedback to make recommendations.

"To Gloss Or Not To Gloss": An Investigation Of Reading Comprehension Online, Lara Lomicka Jan 1998

"To Gloss Or Not To Gloss": An Investigation Of Reading Comprehension Online, Lara Lomicka

Faculty Publications

This pilot study investigated the effects of multimedia reading software on reading comprehension. Specifically, the study aimed to explore how multimedia annotations influence the level of comprehension. Twelve college students enrolled in a second semester French course were instructed to think aloud during the reading of text on the computer screen. Participants read the text under one of three conditions: full glossing, limited glossing, or no glossing. In addition, a tracker was set up in the software to record the amount and type of glosses, and length of time that each was consulted. The raw data clearly indicate an increase …

Hematite And Calcite Coatings On Fossil Vertebrates, B. A.O. Huiming, Paul L. Koch, Robert P. Hepple Jan 1998

Hematite And Calcite Coatings On Fossil Vertebrates, B. A.O. Huiming, Paul L. Koch, Robert P. Hepple

Faculty Publications

Hematite coatings are common on vertebrate fossils from Paleocene/Eocene paleosol deposits in the Bighorn Basin, Wyoming. In general, hematite coatings are found only on fossils and are limited to soils exhibiting hydromorphic features and moderate maturity. Pétrographie and isotopic evidence suggests that hematite and micritic calcite formed at nearly the same time in a pedogenic environment, whereas sparry calcite formed later at greater burial depths. The parent material of paleosols is rich in iron, supplying an ample source of iron for hematite formation. Decomposition of animal tissues around bones may enhance the weathering of iron-bearing minerals in soils surrounding carcasses, …

All Or Nothing, Or Maybe Cooperation: Attorney General Power, Conduct, And Judgment In Relation To The Work Of An Independent Counsel, John Q. Barrett Jan 1998

All Or Nothing, Or Maybe Cooperation: Attorney General Power, Conduct, And Judgment In Relation To The Work Of An Independent Counsel, John Q. Barrett

Faculty Publications

This Article considers the allocation of power under the independent counsel law between the Attorney General along with the Department of Justice and the independent counsel whose appointment the Attorney General has triggered. Although the law explicitly transfers much of an Attorney General's lawful power to an independent counsel, it does not go far enough in reallocating that power. Thus, it leaves a fundamental gap between what the current statute purports independent counsel to be and what it actually empowers independent counsel to accomplish. After an introduction in Part I, Part II of this article reviews the current legal provisions, …

Fraud And Federalism: Preempting Private State Securities Fraud Causes Of Action, Michael A. Perino Jan 1998

Fraud And Federalism: Preempting Private State Securities Fraud Causes Of Action, Michael A. Perino

Faculty Publications

The passage of the Private Securities Litigation Reform Act of 1995 has engendered a significant forum shift in class action securities fraud litigation, from federal to state court. This unintended by-product of the Act has reignited debate over our dual federal-state system of securities regulation and in turn has inspired a discussion as to whether Congress should now preempt state securities fraud causes of action. This article argues that preemption is an appropriate, but not the only, solution to these concerns. To support this argument, this article first traces the history of dual state-federal securities regulation within the context of …

Women, The Law, And Cults: Three Avenues Of Legal Recourse: New Rape Laws, Violence Against Women Act, And Antistalking Laws, Robin A. Boyle Jan 1998

Women, The Law, And Cults: Three Avenues Of Legal Recourse: New Rape Laws, Violence Against Women Act, And Antistalking Laws, Robin A. Boyle

Faculty Publications

The author examines three avenues of legal recourse that are available to society at large, but may not be well-known to women in cults, their families, and their potential mental health providers. These avenues for recourse are improved rape laws now available in every state; recently-enacted federal legislation -- the 1994 Violence Against Women Act; and recently-enacted state and federal antistalking laws. The author developed this article from her speech delivered at the annual American Family Foundation conference on May 30, 1997, in Philadelphia, PA.

Discovery In International Legal Developments Year In Review: 1997, Christopher J. Borgen Jan 1998

Discovery In International Legal Developments Year In Review: 1997, Christopher J. Borgen

Faculty Publications

U.S. law provides litigants with a variety of means to obtain evidence from foreign jurisdictions. The Federal Rules of Civil Procedure (the Federal Rules) and rules of state courts may be used if a U.S. court has jurisdiction over the person who is in control of the evidence in question. Section 1783 of tide 28 of the United States Code provides a means for serving a subpoena on U.S. nationals or residents abroad. Litigants may also obtain foreign discovery through letters rogatory as permitted by 28 U.S.C. § 1781 and treaties such as the Hague Convention on Taking Evidence (the …

Compilation Techniques For Out-Of-Core Parallel Computations, M. Kandemir, A. Choudhary, J. Ramanujam, R. Bordawekar Jan 1998

Compilation Techniques For Out-Of-Core Parallel Computations, M. Kandemir, A. Choudhary, J. Ramanujam, R. Bordawekar

Faculty Publications

The difficulty of handling out-of-core data limits the performance of supercomputers as well as the potential of the parallel machines. Since writing an efficient out-of-core version of a program is a difficult task and virtual memory systems do not perform well on scientific computations, we believe that there is a clear need for compiler directed explicit I/O approach for out-of-core computations. In this paper, we first present an out-of-core compilation strategy based on a disk storage abstraction. Then, we offer a compiler algorithm to optimize locality of disk accesses in out-of-core codes by choosing a good combination of file layouts …

Cognitive Agents, Michael N. Huhns, Munindar P. Singh Jan 1998

Cognitive Agents, Michael N. Huhns, Munindar P. Singh

Faculty Publications

Several researchers have proposed using cognitive concepts as a semantic basis for agent communications (M.N. Huhns and M.P. Singh, 1997). One of the leading candidates for such a semantics is based on Arcol, the communication language used within Artimis. Interestingly, this application (not only of Arcol, but also in general) appears extremely misguided. The intentional concepts are well suited to designing agents, but are not suited to giving a basis to a public, standardizable view of communication. A challenge for using the cognitive concepts is that although they are natural in several respects and can guide implementations, full blown implementations …

Personal Assistants, Michael N. Huhns, Munindar P. Singh Jan 1998

Personal Assistants, Michael N. Huhns, Munindar P. Singh

Faculty Publications

Already there are simple personal agents to help with some of our shopping. There are agents to track stocks in our portfolios, advise us on how to use particular software products, and arrange meetings within corporate workgroups. However, none of these agents takes more than one aspect of our activities into account, nor do they adapt easily to our preferences. Personal assistants, on the other hand, are agents that can represent individuals on the Web. They help users in their day-to-day activities, especially those involving information retrieval, negotiation, or coordination. A personal assistant might schedule a meeting and then, based …

Workflow Agents, Michael N. Huhns, Munindar P. Singh Jan 1998

Workflow Agents, Michael N. Huhns, Munindar P. Singh

Faculty Publications

Software agents as user agents, resource agents, and brokers may be able to enhance usefulness of workflow applications. Workflow technology is important to network computing because workflows exist naturally wherever distributed resources are interrelated. The problem with current workflow technology is that it is often too rigid. The lack of freedom accorded to human participants causes workflow management systems to appear unfriendly. As a result, they are often ignored or circumvented. This rigidity also causes productivity losses by making it harder to accommodate the flexible, ad hoc reasoning of human intelligence. Another challenge is that system requirements are rarely static. …

All Agents Are Not Created Equal, Michael N. Huhns, Munindar P. Singh Jan 1998

All Agents Are Not Created Equal, Michael N. Huhns, Munindar P. Singh

Faculty Publications

As the technology advances, we can expect the development of specialized agents to be used as standardized building blocks for information systems. Two trends lend credence to such a prediction. First, software systems in general are being constructed with larger components, such as ActiveX and JavaBeans, which are becoming closer to being agents themselves. They have more functionality than simple objects, respond to events autonomously, and, most importantly, respond to system builders at development time, as well as to events at runtime. Moreover, there is a move toward more cooperative information systems, in which the architecture itself plays an important …
