Mutual Fund Style, Characteristic-Matched Performance Benchmarks and Activity Measures: A New Approach

We propose a new approach for measuring mutual fund style and constructing characteristic-matched performance benchmarks that requires only portfolio holdings and two reference portfolios in each style dimension. The characteristic-matched performance benchmark literature typically follows a bottom-up approach by first matching individual stocks with benchmarks and then obtaining a portfolio’s excess return as a weighted average of the excess returns on each of its constituent stocks. Our approach is fundamentally different in that it matches portfolios and benchmarks directly. We illustrate our approach using portfolio holdings of 1183 fund managers over the period 2002-2009. We characterize the cross-section of fund manager styles and show how average style changes over time. The tracking error volatilities of our characteristic-matched benchmarks compare favorably with those of existing methods. Using our benchmarks we explore the link between activity and performance.Performance Measurement; Tailored Benchmark; Characteristic Matching; Size Profile; Growth Profile; Activity; Excess Return.

The utilization of neural nets in populating an object-oriented database

Existing NASA supported scientific data bases are usually developed, managed and populated in a tedious, error prone and self-limiting way in terms of what can be described in a relational Data Base Management System (DBMS). The next generation Earth remote sensing platforms (i.e., Earth Observation System, (EOS), will be capable of generating data at a rate of over 300 Mbs per second from a suite of instruments designed for different applications. What is needed is an innovative approach that creates object-oriented databases that segment, characterize, catalog and are manageable in a domain-specific context and whose contents are available interactively and in near-real-time to the user community. Described here is work in progress that utilizes an artificial neural net approach to characterize satellite imagery of undefined objects into high-level data objects. The characterized data is then dynamically allocated to an object-oriented data base where it can be reviewed and assessed by a user. The definition, development, and evolution of the overall data system model are steps in the creation of an application-driven knowledge-based scientific information system

The influence of breeding young swine upon the parents, the offspring and the breed

Approved, F.B. MumfordTypescriptM.A. University of Missouri 1913There is no animal contributing directly to the food supply of the people which is at the same time so generaly kept and so little understood as the pig. Nor is there one which, intimately associated as it is with their welfare, is so generally appreciated by the rural classes. While some farmers formerly bred and fed pigs for the purpose of consuming inferior and waste stuff and the production of manure, the farmer of to-day keeps a sow for the profit and satisfaction which she returns him in addition to the above. There are few farms in the United States today upon which there is not a brood sow. The sow occupies a high position with the farmer and contributes more to his prosperity than almost anything to which he devotes attention. America has long been known as a swine-producing country of surpassing excellence, and claims to produce and consume more pork than any other nation. Missouri alone, in 1907. sent to market 3,878,863 head of hogs valued at $38,788,630, and at that time Missouri ranked as fifth state in the Union in swine production. From these statistics one can realize the important part which swine take in the welfare of our nation.Includes bibliographical reference

Pax1 and Pax9 activate Bapx1 to induce chondrogenic differentiation in the sclerotome.

We have previously shown that the paired-box transcription factors Pax1 and Pax9 synergistically act in the proper formation of the vertebral column. Nevertheless, downstream events of the Pax1/Pax9 action and their target genes remain to be elucidated. We show, by analyzing Pax1;Pax9 double mutant mice, that expression of Bapx1 in the sclerotome requires the presence of Pax1 and Pax9, in a gene dose-dependent manner. By using a retroviral system to overexpress Pax1 in chick presomitic mesoderm explants, we show that Pax1 can substitute for Shh in inducing Bapx1 expression and in initiating chondrogenic differentiation. Furthermore, we demonstrate that Pax1 and Pax9 can transactivate regulatory sequences in the Bapx1 promoter and that they physically interact with the Bapx1 promoter region. These results strongly suggest that Bapx1 is a direct target of Pax1 and Pax9. Together, we conclude that Pax1 and Pax9 are required and sufficient for the chondrogenic differentiation of sclerotomal cells

Clients\u27 Experiences Giving Gifts to Therapists

Nine therapy clients were interviewed regarding their experiences of giving gifts to therapists. Data were analyzed using consensual qualitative research. In describing a specific event when they gave a gift that was accepted, participants described having a good relationship with the therapist and usually identified their therapy concerns as relationship or family struggles or both. Most bought a relatively inexpensive gift they thought their therapist would like and gave it during a nontermination session to express appreciation or mark an important life event. Most participants acknowledged mixed emotions when giving the gift and noted that any discussion of the gift was brief and did not explore its deeper meaning. Nevertheless, most participants perceived that gift events positively affected them and their therapists

Preliminary Report on a Stratified Late Archaic-Woodland Era Rockshelter in Rogers County, Oklahoma

In northeastern Oklahoma, very little is known about the transition from the Late Archaic to the Woodland period (Wyckoff and Brooks, 1983: 55). To date, most of the archeological evidence documenting this time period has been derived from sites with mixed or otherwise uncertain components. In this report, we present a preliminary description of a small rockshelter, 34RO252, which has a Late Archaic deposit stratigraphically below a Woodland era cultural deposit. These two deposits are unmixed, discrete, and are physically separated by an apparently sterile clay soil horizon. It is anticipated that the stratified cultural deposits at this site will help characterize the transition from the Late Archaic to the Early Woodland period along the Verdigris River in northeast Oklahoma. This site was first reported in April 1994 by two men who had discovered partially exposed human skeletal remains located in the rear remnant of a rockshelter at Oologah Lake in Rogers County, Oklahoma. The two men illegally excavated the remains and removed them from the site. 1 The rockshelter where the remains originated was subsequently examined by the authors and additional skeletal material was identified, in situ, in an exposed soil profile. A series of three radiocarbon assays, described below, placed the cultural deposit and the human remains within the Late Archaic-Woodland period (circa 780 B.C. to A.O. 900).2 This site is provisionally classified as corresponding to a cultural sequence that includes the old Grove C described by Purrington and Vehik

Referencing Sources of Molecular Spectroscopic Data in the Era of Data Science: Application to the HITRAN and AMBDAS Databases

The application described has been designed to create bibliographic entries in large databases with diverse sources automatically, which reduces both the frequency of mistakes and the workload for the administrators. This new system uniquely identifies each reference from its digital object identifier (DOI) and retrieves the corresponding bibliographic information from any of several online services, including the SAO/NASA Astrophysics Data Systems (ADS) and CrossRef APIs. Once parsed into a relational database, the software is able to produce bibliographies in any of several formats, including HTML and BibTeX, for use on websites or printed articles. The application is provided free-of-charge for general use by any scientific database. The power of this application is demonstrated when used to populate reference data for the HITRAN and AMBDAS databases as test cases. HITRAN contains data that is provided by researchers and collaborators throughout the spectroscopic community. These contributors are accredited for their contributions through the bibliography produced alongside the data returned by an online search in HITRAN. Prior to the work presented here, HITRAN and AMBDAS created these bibliographies manually, which is a tedious, time-consuming and error-prone process. The complete code for the new referencing system can be found at \url{https://github.com/hitranonline/refs}.Comment: 11 pages, 5 figures, already published online at https://doi.org/10.3390/atoms802001
