Policy and Practice Brief: The Federal Earned Income Tax Credit; A Work Incentive That Puts More Money in a Paycheck and Saves on Taxes

This brief explores the Earned-Income Tax Credit which is a special tax benefit for working people who earn a low or moderate income. Reviewed are the specifics of the tax credit along with application for how it can support the career development aspirations of beneficiaries with disabilities

In search of meta-knowledge

Development of an Intelligent Information System (IIS) involves application of numerous artificial intelligence (AI) paradigms and advanced technologies. The National Aeronautics and Space Administration (NASA) is interested in an IIS that can automatically collect, classify, store and retrieve data, as well as develop, manipulate and restructure knowledge regarding the data and its application (Campbell et al., 1987, p.3). This interest stems in part from a NASA initiative in support of the interagency Global Change Research program. NASA's space data problems are so large and varied that scientific researchers will find it almost impossible to access the most suitable information from a software system if meta-information (metadata and meta-knowledge) is not embedded in that system. Even if more, faster, larger hardware is used, new innovative software systems will be required to organize, link, maintain, and properly archive the Earth Observing System (EOS) data that is to be stored and distributed by the EOS Data and Information System (EOSDIS) (Dozier, 1990). Although efforts are being made to specify the metadata that will be used in EOSDIS, meta-knowledge specification issues are not clear. With the expectation that EOSDIS might evolve into an IIS, this paper presents certain ideas on the concept of meta-knowledge and demonstrates how meta-knowledge might be represented in a pixel classification problem

Policy and Practice Brief: PASS: SSI’s Plan for Achieving Self-Support; This Self-Directed Vocational Rehabilitation Plan is an Alternative Funding Source to Support a Range of Work Goals

This primer provides an in-depth overview of the Plan for Achieving Self-Support (PASS), a Supplemental Security Income work incentive program. Detailed is how the PASS can support self-directed vocational rehabilitation and its impact on an individual’s benefits as they progress toward their established work goal. The process for completing a PASS Application is also reviewed

Appellation of Origin Status and Economic Development: A Case Study of the Mezcal Industry

Mezcal is an alcoholic beverage produced only in selected regions of Mexico under appellation of origin status from the Word Intellectual Property Organization. While it has been produced in Mexico for many centuries, mezcal’s appellation of origin was only granted in 1995. Therefore efforts to produce and market it as a premium product have a relatively short history. This case study examines developments in the production and marketing of this unique product, and the activities of the marketing cooperative El Tecuán in Guerrero State in this process.mezcal, Mexico, appellation, marketing, cooperative, Community/Rural/Urban Development, Marketing,

Logic programming and metadata specifications

Artificial intelligence (AI) ideas and techniques are critical to the development of intelligent information systems that will be used to collect, manipulate, and retrieve the vast amounts of space data produced by 'Missions to Planet Earth.' Natural language processing, inference, and expert systems are at the core of this space application of AI. This paper presents logic programming as an AI tool that can support inference (the ability to draw conclusions from a set of complicated and interrelated facts). It reports on the use of logic programming in the study of metadata specifications for a small problem domain of airborne sensors, and the dataset characteristics and pointers that are needed for data access

SPAN: Astronomy and astrophysics

The Space Physics Analysis Network (SPAN) is a multi-mission, correlative data comparison network which links science research and data analysis computers in the U.S., Canada, and Europe. The purpose of this document is to provide Astronomy and Astrophysics scientists, currently reachable on SPAN, with basic information and contacts for access to correlative data bases, star catalogs, and other astrophysic facilities accessible over SPAN

An Analysis of Renewable Resource Development Alternatives for the Northern Arid Region of Mexico: Study Prospectus

In 1980, IIASA joined with the Centro de Investigation en Quimica Aplicada (CIQA) in order to study alternative production chains based on the renewable resources of the Northern Arid Region of Mexico. This study applied the "WELMM Approach" developed at IIASA. Its objective was to account for the basic resources used and processed along alternative production chains, from cultivation and harvesting of the plants to the final products. WELMM analyses of each of the production chains are now being completed, and IIASA and CIQA have decided to expand their cooperative efforts to include an analysis of alternative development projects for the Northern Arid Region based on these production chains. This paper presents a prospectus for the expanded study

Potential Mission Scenarios Post Asteroid Crewed Mission

A deep-space mission has been proposed to identify and redirect an asteroid to a distant retrograde orbit around the moon, and explore it by sending a crew using the Space Launch System and the Orion spacecraft. The Asteroid Redirect Crewed Mission (ARCM), which represents the third segment of the Asteroid Redirect Mission (ARM), could be performed on EM-3 or EM-4 depending on asteroid return date. Recent NASA studies have raised questions on how we could progress from current Human Space Flight (HSF) efforts to longer term human exploration of Mars. This paper will describe the benefits of execution of the ARM as the initial stepping stone towards Mars exploration, and how the capabilities required to send humans to Mars could be built upon those developed for the asteroid mission. A series of potential interim missions aimed at developing such capabilities will be described, and the feasibility of such mission manifest will be discussed. Options for the asteroid crewed mission will also be addressed, including crew size and mission duration

Wine World Estates

Wine World Estates has been a wholly owned subsidiary of the Nestle Company for a quarter of a century. This rapidly growing business unit has been put up for sale, and Walter Klenz, its CEO, is leading a management inspired leveraged buyout in competition with two other large potential buyers. His challenge is to arrange for a financing package of more than $350 million to successfully achieve his objective
