Jeff Pan oral history interview and transcript
No full textThis recording and transcript form part of a collection of oral history interviews conducted by the Chao Center for Asian Studies at Rice University. This collection includes audio recordings and transcripts of interviews with Asian Americans native to or living in Houston.Dr. Jeff Gee-shang Pan is a Chinese-American geophysicist with extensive experience in the petroleum industry. He was born in Taiwan and left for the US to pursue his doctoral degree in Geophysics at Princeton University. After a year as a postdoctoral researcher, he joined the Atlantic Richfield Company (ARCO). In 1998, Dr. Pan joined Oryx, which first merged with Kerr McGee and then later with Anadarko. During his tenure at Anadarko, Dr. Pan and his family were expatriated to Beijing, China where he served as an executive who managed their China operations and joint venture partners. Dr. Pan has been involved in the Chinese American Petroleum Association since 2000, where he held a variety of leadership positions, including President and Director of BOD. He also served a two-year term as President of the North American Chinese Geoscientists Association. Dr. Pan encourages future generations of Chinese-Americans to engage in public discourse and pursue leadership positions through hard work and tenacity, and he advises Chinese-Americans to be proud of their heritage and to leave a positive legacy
Designing Ontology-Based Data Access Solutions: Representation and Reasoning Support
No full textWhile OBDA has been the focus of many different studies in recent years, these studies typically have focused on the core aspects of OBDA, in particular on query answering. Less attention, in this context, has been dedicated to other aspects such as ontology representation, ontology visualization, and intentional reasoning. From the experience matured in the last few years in working with OBDA, it is clear that these problems, while also representing independent research fields, all play a significant part in the construction of the architecture of a full-fledged OBDA system, and therefore must be addressed. Unfortunately, the results that are found in literature regarding these issues are unsatisfactory when taken in the context of OBDA, because they are not tailored towards the languages and the applications that are adopted under the OBDA framework. This thesis addresses these issues and presents solutions for them in the context of the OBDA framework. The integration of these solutions and techniques into an OBDA system allows to provide users with full support for all
OBDA-related activities. We briefly summarize in the following the main contributions provided in this thesis: we present the novel Graphol language for the graphical specification of DL ontologies; we study the problem of approximating DL ontologies specified in an expressive source language in terms of less expressive target languages; we deal with core intentional reasoning services over an ontology, devising efficient methods and implementations that are specifically tailored towards languages that are suitable for OBDA

Semantically enabling web service repositories
No full textThe success of the Web service technology has brought topics such as software reuse and discovery once again on the agenda of software engineers. While there are several efforts towards automating Web service discovery and composition, many developers still search for services via online Web service repositories and then combine them manually. However, from our analysis of these repositories, it yields that, unlike traditional software libraries, they rely on little metadata to support service discovery. We believe that the major cause is the difficulty of automatically deriving metadata that would describe rapidly changing Web service collections. In this paper, we discuss the major shortcomings of current Web service repositories and, as a solution, we report on how to use techniques developed in the context of the Semantic Web (ontology learning, service annotation tools, automatic classifiers, metadata based presentation) to improve the current situatio
Semantic Import: An Approach for Partial Ontology Reuse
No full textState of the art formalisms for distributed ontology integration provide ways to express semantic relations between concepts belonging to different ontologies. However, the extensive usage of multiple distributed ontologies requires the capability for expressing different forms of mappings, which extend the semantic relations between concepts studied so far. In this paper, we propose an extension of the formalism of Distributed Description Logic (DDL) to represent mappings between concepts as well as mappings between relations, and an effective decision procedure for reasoning with multiple ontologies bridged with these mappings
Reliability of Child SCAT 3 Component Scores in Non-Concussed Children at Rest and After Exercise
No full textTitle: Reliability of Child SCAT 3 Component Scores in Children at Rest and Following Exercise
Author Names: Jeff Billeck, BPE, CAT(C)1, Mike Ellis, MD2, Jeff Leiter, PhD2, Joanne Parsons, PhD, BPT3. Jason Peeler, PhD, CAT(C)4
Problem: A lack of research exists regarding the test-retest reliability of the Child Sport Concussion Assessment Tool 3 (Child SCAT 3) in healthy non-concussed adolescent females in both baseline and post-exercise settings.
Method: This study consisted of two testing sessions. Within each session the Child Sport Concussion Assessment Tool 3 (Child SCAT 3) was administered once prior to exercise and once after a bout of exercise.
Results: Individual component scores displayed a wide range of reliability and response stability values. A positive correlation existed within one session, between child symptom scores and slower rates of heart rate recovery after exercise.
Conclusions: Overall, the Child SCAT 3 appears to be a moderately reliable assessment tool when used to evaluate uninjured female children. However, further research is required to clarify the exact sources of method error within individual Child SCAT 3 component scores.May 201
Overview of the Author Profiling Task at PAN 2013
No full text[EN] This overview presents the framework and results for the Author Profiling
task at PAN 2013. We describe in detail the corpus and its characteristics,
and the evaluation framework we used to measure the participants performance to
solve the problem of identifying age and gender from anonymous texts. Finally,
the approaches of the 21 participants and their results are described.The author profiling task @PAN-2013 was an activity of the WIQ-EI IRSES project (Grant No. 269180) within the FP 7 Marie Curie People Framework of the European Commission. We want to thank the Forensic Lab of the Universitat Pompeu Fabra Barcelona for sponsoring the award for the winner team. The work of the first author was partially funded by Autoritas Consulting SA and by Ministerio de Economía y Competitividad de España under grant ECOPORTUNITY IPT-2012-1220-430000. The work of the second author was in the framework the DIANA-APPLICATIONS-Finding Hidden Knowledge in Texts: Applications (TIN2012-38603-C02-01) project, and the VLC/CAMPUS Microcluster on Multimodal Interaction in Intelligent Systems.
