Space Stations And The Law: Selected Legal Issues -- Background Paper, U.S. Congress, Office Of Technology Assessment

Space Law Documents

Multinational space station activities will raise fundamental legal issues. The laws we take for granted on Earth--e.g., those that regulate commerce, property, criminal activity, and personal interactions--may not be available in space or may conflict with similar laws held by other nations. This background paper analyzes some of the legal consequences of developing and operating an international space station. It describes the different ways that an international space station might be owned and operated and explains how each could affect the rights and responsibilities of the u.s. Government and its citizens. The background paper gives special attention to the application …

Lambing Performance Of Morlam And Dorset Ewes Under Accelerated Lambing Systems, L. C. Iniguez, R. L. Quaas, L. Dale Van Vleck

Department of Animal Science: Faculty Publications

Two accelerated lambing systems, Morlam using Morlam sheep (USDA, Beltsville 1966 to 1975) and Carnal using Dorset ewes (Cornell 1978 to 1981), were evaluated for first lambing ages, interlambing intervals and conception probabilities. Morlam ewes were continuously exposed to rams over the year, while Carnal Dorset ewes were exposed every other month. Morlam lambs were mated as early as 367 d of age and Carnal Dorset lambs as early as 340 d. Early lambing was associated with higher rates of perinatal mortality (P>.05) and smaller litter size (P<.O1). Lambing years among Morlam ewes and season of birth of Carnal Dorset ewes influenced (P<.01) their first lambing ages. Lambing intervals averaged 293 and 303 d among Morlam and Carnal Dorset ewes, respectively. Age at first lambing and season in which the previous lambing occurred with influential factors (P<.01) on lambing intervals of Morlam ewes; longer intervals resulted when ewe lambs were mated at early ages (<12 mo), and when the previous lambing occurred in winter. Estimates of conditional probabilities of conception by month given the occurrence of estrus, reflected seasonal changes in both systems. The overall probability of conception for the Morlain system (P=.16) was relatively higher than that for the Carnal Dorset system (P=.14); numbers of lambings per ewe per yr were 1.28 and 1.21, respectively. Estimates of heritability for age at first lambing, lambing interval and conception probability were. 31, .06 and .30, respectively.

This 100th Annual Report contains lists of current faculty, active projects, refereed journal publications, brief descriptions of research in selected areas, and the financial report for the period July 1, 1985, through June 30, 1986. Research programs in agriculture, home economics, and natural resources at the University of Nebraska have changed greatly since the U.S. Congress approved the establishment of an Agricultural Experiment Station in each state with the passage of the Hatch Act on March 2, 1887. Although Hatch funds account for a smaller proportion of the total research expenditures in the program today, this legislation continues to be …

Economies Of Scale And The New Technology Of Daily Newspapers: A Survivor Analysis, Seth W. Norton, Will Norton Jr.

College of Journalism and Mass Communications: Faculty Publications

The economics of the newspaper industry occupies a special place in industrial organization. Unlike the vast majority of enterprises, this business is intimately linked to the protection of freedom of expression. Constitutional democracies generally have monitored it with special care. In the United States the Newspaper Preservation Act of 1970 provides some antitrust immunity for segments of the industry. Ignoring a captive regulation (pro-producer, wealth-maximizing) rationale for the act, we may presume that the United States Congress deems daily newspaper viability as an objective superior to the conventional reasons for antitrust. The received logic rests on the notion that newspapers …

Surface Segregation In Binary Alloys, Uresh Vahalia, Peter A. Dowben, Allen Miller

Peter Dowben Publications

A semiempirical calculation is outlined that allows analysis of experimental results for the apparent surface concentration of binary alloys, obtained by x-ray photoelectron spectroscopy, (XPS). A segregation profile giving the enrichment of the segregating element at and near the surface is obtained from the analysis. Using previously published data for Cu ₁₇ Ni ₈₃ ( 100) and Cu ₁₇ Ni ₈₃ ( 111 ), it is shown that copper segregation is not restricted to the first few layers, but instead extends significantly into the selvedge (near-surface) region. This occurrence is not explainable by the use of present ideal solution models. …

An Attribute Analysis Of Sandy Lake Ware From Norman County And North Central Minnesota, Lynelle A. Peterson

Department of Anthropology: Theses and Student Research

Sandy Lake Ware, is a Late Woodland-Early Historic ceramic ware, found throughout northern Minnesota and parts of North Dakota, Wisconsin, Ontario, and Manitoba. No formal analysis of this ware has occurred since its definition by Cooper and Johnson in 1964. As a result, the basic information regarding the attributes, the interrelationship between attributes, and factors leading to variation within Sandy Lake Ware are poorly understood.

This thesis analyses the relationship between between attributes from 1459 vessels collected in Norman county, and north central Minnesota, using the chi square statistical method of analysis. This thesis also tests the implicit assumption of …

Personality Type Differences Of Licensed Nurses And Implications For Continuing Education, Sally L. Cole

Department of Agricultural Leadership, Education, and Communication: Dissertations, Theses, and Student Research

This research was undertaken with the specific intent to develop a personality profile of licensed nurses (RN's and LPN's) which would provide a basis for recommendations of techniques to be utilized in continuing education programs for nurses. The instrument selected to measure the psychological type preference, and thus create the personality profile, was the Myers-Briggs Type Indicator (MBTI) Carl Jung's theory pertaining to personality, known as type theory, states that individuals perceive and respond to information differently according to their psychological type preference which is measured by the MBTI. There was considerable correlation between the findings of this study and …

Union-Nonunion Earnings Differentials And The Decline Of Private-Sector Unionism, Richard Edwards, Paul Swaim

Department of Economics: Faculty Publications

Recent years have been difficult ones for the American labor movement. Especially during the past half-decade, the economic and political environment for unions has become increasingly hostile-dominated by a growing anti-union sentiment in manage ment; the adverse effects of industrial restructuring, import competition, deregulation, and high unemployment; and the tightening constraints of a labor law and NLRB enforcement mechanism that have become markedly less supportive of unions. These and other external changes, as well as some continuing internal weaknesses, have thrust unions into a period of declining union membership, eroding bargaining strength, repeated contract concessions, and what at least some …

Phosphotransferase Activity In Clostridium Acetobutylicum From Acidogenic And Solventogenic Phases Of Growth, Robert W. Hutkins, Eva R. Kashket

Department of Food Science and Technology: Faculty Publications

Clostridium acetobutylicum cells, when energized with fructose, transported and phosphorylated the glucose analog 2-deoxyglucose by a phosphoenolpyruvate-dependent phosphotransferase (PT) system. Butanol up to 2% did not inhibit PT activity, although its chaotropic effect on the cell membrane caused cellular phosphoenolpyruvate and the 2-deoxyglucose-6-phosphate to leak out. Cells harvested from the solventogenic phase of batch growth had a significantly lower PT activity than did cells from the acidogenic phase.

The Mechanical Control Of Bushpig, Potamochoerus Porcus, In Zimbabwe, Michael La Grange

Vertebrate Pest Conference Proceedings: 12th (1986)

Bushpig, Potamocheorus porcus, occurring naturally in the high rainfall areas of Zimbabwe, have become a major threat to maize producers in the country. Traditional means of control including hunting have been unsuccessful in keeping the numbers to a tolerable level owing to the secretive and cunning nature of the animal. The use of poisons has been discouraged because of indiscriminate use and problems of secondary poisoning, so alternative methods of mechanical control were sought. Several methods evolved during experimentation, producing a strategy to control bushpig throughout the year.

Approximating Prediction Error Variances For Multiple Trait Sire Evaluations, S. A. Greenhalgh, R. L. Quaas, L. Dale Van Vleck

Department of Animal Science: Faculty Publications

The coefficient matrix for multiple trait (milk, fat, and protein) mixed model equations may be too large to obtain prediction error variances from inverse elements. The commonly used reciprocals of diagonal elements may not be accurate approximations when sire relationships or multiple traits are included since much information is contained in off-diagonal elements. Approximations incorporating increased information from coefficient matrix were compared with actual prediction error variances for multiple trait evaluations for milk, fat, protein, and dollar value (relationships included) of 229 Ayrshire and 248 Brown Swiss bulls. Six approximations were selection index using number of daughter records, inverses of …

Regulation Of Gonadotropin Secretion In The Male: Effect Of An Aromatization Inhibitor In Estradiol-Implanted, Orchidectomized Dogs, C. Awoniyi, T. Hasson, V. Chandrashekar, R. E. Falvo, B. D. Schanbacher

Roman L. Hruska U.S. Meat Animal Research Center: Reports

Testosterone is aromatized to estradiol in both peripheral tissues and the central nervous system. Various authors have suggested that this conversion in the male may be prerequisite for the regulation of gonadotropin secretion by testosterone. Previously, it was reported that inhibition of central nervous system aromatase caused a significant increase in plasma LH in the presence of physiologic testosterone levels (Winter et a!, 1983). In order to confirm whether aminoglutethimide, the aromatase inhibitor used in our previous study, either blocked aromatization, or the action of estradiol, the following study was conducted. Fifteen male mongrel dogs were equally divided into three …

The Future of Testing

There will be no divining of the future here- no megatrends, no reference to Orwell (except this one). What little we truly know about the future does not bear mentioning. Nor shall I refer to micro-computers, data banks, and other gaudy paraphernalia that the future holds for us. The future is best seen in a rear-view mirror. We can at least hope to see more clearly the recent past we have traversed. Appearances of rapid change are usually superficial. If we see the past and present clearly, we will know as much of our future as it is ever permitted …

10. Needed Directions For Measurement In Work Settings, Mary L. Tenopyr

The Future of Testing

One of the greatest needs in psychology today is the establishment of more rigorous psychological measurement practices in the millions of work settings throughout the country. Today, any semblance of precise measurement appears to be limited to the largest of employers. Only the biggest corporations and the major governmental units , such as those in the federal government, have the scientific staffs to conduct the research and development work necessary to provide the type of measurement that is so needed.

Psychological measurement in work settings has a profound effect upon American society. Indeed, it affects almost all citizens' lives. Employees, …

I have been asked to describe a desirable future by canoeing through the rapids of psychometric fashions , disgruntled test takers, passive publishers, worried professionals and their righteous associations, and future islands of unpredictable theory.

6. The Future Of Testing For Licensure And Certification Exam I Nations, Michael T. Kane

The Future of Testing

Licensure and certification examinations constitute a major use of tests in the United States, and since licensure and certification provide obvious benefits to the persons licensed or certified and to the public, their use is not likely to decrease. Rather, the usage of such examinations to document competence is likely to continue to increase, although perhaps more slowly than it has in the recent past.

Critics of licensure have argued that licensure tends to benefit the licensed profession more than the public and that the benefits of licensure to the public do not always justify the costs (e.g., see Hogan, …
