TECHNOLOGICAL ADAPTATION TO RESOURCE SCARCITY IN THE U.S. LUMBER INDUSTRY

This paper provides an econometric investigation of the role of a renewable natural resource, sawlogs, in the production of lumber over the period 1950-1974. The economic scarcity of sawlogs is confirmed. Within a given production technology, the potential for substitution among capital, labor and sawlog inputs is greatly restricted but not impossible. Technological change has been strongly labor-saving but has had a negligible effect on wood requirements. Consequently, the real price of lumber has risen, stimulating development of substitute wood products. Continued decline of the industry is anticipated.Research and Development/Tech Change/Emerging Technologies, Resource /Energy Economics and Policy,

Upper midwest regional capstone award program

Five Upper Midwest universities—Iowa State University, Michigan State University, Michigan Technological University, the University of Wisconsin-Madison, and the University of Wisconsin-Stevens Point—all offer a capstone course or capstone sequence for senior students in forestry that results in a written paper or project report. The five universities have collaborated with private industry and public agencies to develop an award program for these capstone reports. In this paper we describe the capstone courses taught by each of the universities and their project requirements. We summarize experience gained on the administrative and judging requirements and procedures, including those relating to costs and funding, during the first year of the competition. We also discuss the benefits of the program to students, faculty and the participating industries and agencie

Cloud microphysics and aerosol indirect effects in the global climate model ECHAM5-HAM

The double-moment cloud microphysics scheme from ECHAM4 has been coupled to the size-resolved aerosol scheme ECHAM5-HAM. ECHAM5-HAM predicts the aerosol mass and number concentrations and the aerosol mixing state. This results in a much better agreement with observed vertical profiles of the black carbon and aerosol mass mixing ratios than with the previous version ECHAM4, where only the different aerosol mass mixing ratios were predicted. Also, the simulated liquid, ice and total water content and the cloud droplet and ice crystal number concentrations as a function of temperature in stratiform mixed-phase clouds between 0 and –35°C agree much better with aircraft observations in the ECHAM5 simulations. ECHAM5 performs better because more realistic aerosol concentrations are available for cloud droplet nucleation and because the Bergeron-Findeisen process is parameterized as being more efficient. The total anthropogenic aerosol effect includes the direct, semi-direct and indirect effects and is defined as the difference in the top-of-the-atmosphere net radiation between present-day and pre-industrial times. It amounts to –1.8 W m^−2 in ECHAM5, when a relative humidity dependent cloud cover scheme and present-day aerosol emissions representative for the year 2000 are used. It is larger when either a statistical cloud cover scheme or a different aerosol emission inventory are employed

Leni Riefenstahl\u27s Olympia : Brilliant Cinematography or Nazi Propaganda?

This article discusses whether or not the documentary on the 1936 Summer Olympic Games entitled Olympia was more than just a very well made sports film, but produced with the purpose of promoting Nazi propaganda for national socialism

Recommended Educational Experiences for High School Athletic Directors (ADs)

A national study of 400 high school principals was conducted to determine their recommendations in terms of the most appropriate informal and formal education (experiences) for would-be high school athletics directors. Specifically, the principals were asked to rate each of 19 items/questions relating to formal or informal education efforts or achievements by means of a 5-point likert scale. A secondary purpose was to ascertain how the respondents rated each of the then proposed sport management core content areas (areas of formal course work), as recommended by the Sport Management Program Review Council. Only two core content areas -- (1) legal aspects of sport and (2) budget and finance in sport -- were deemed to be essential or very important by a majority of 233 respondents (58.25% return). The formal course work that the largest number of principals felt was not very important/irrelevant was research in sport

Preferred Player Characteristics and Skills of Division I Men\u27s Basketball Coaches

A national survey of selected men’s basketball coaches, at the NCAA Division I level, revealed how essential the respondents felt certain work ethic characteristics were for successful basketball players on their team. The respondents also revealed how important specific skills or talents were for the success of men’s NCAA men’s Division I basketball programs. The survey was completed by means of a 36-item Likert scale questionnaire. This investigation determined to what degree NCAA Division I coaches should seek specific work ethic characteristics and physical skills/talents in their players

Necessary Education for the Success of Athletics Directors: NCAA Presidents\u27 Perceptions

Given the many demands placed on the current day athletics director, the necessity of appropriate education has become paramount. Several years ago, Leith (1983) recognized the need for athletic administrators to be competent in a variety of skills. Today, the need for athletics directors to be well versed in multiple job-related skills has become even more apparent. The current status of athletic administration among National Collegiate Athletic Association (NCAA) colleges and universities suggest that occupational demands are being placed on sport administrators at an increasing rate (Bradley, 1993; Lea & Loughman 1993; Neilsen, 1990). Copeland and Kirsch (1995) recognized the escalating responsibilities and the inherent demands of contemporary sport in order to maintain competitive programs. It was discovered in a study undertaken by Cleave (1993) that intercollegiate administrators generally perceived their jobs as becoming more complex
