A Potential Understory Flora For Oak Savanna In Iowa, Karl T. Delong, Craig Hooper

Journal of the Iowa Academy of Science: JIAS

Oak savanna occurred in Iowa until the time of settlement and then was degraded rapidly. There were no scientific studies of savanna prior to, or after, settlement, and now no high-quality examples exist within the state. To identify those vascular plants adapted to live in the understory of savanna we examined regional and local flora for species that occurred in both prairie and broken woodland, and for species that occurred m both openings and forest. We then compiled a detailed description of the ecological range of habitats for each of these species. We identified 252 species (39 graminoids, 183 forbs, …

Logic And The Second Law Of Thermodynamics, David Van Den Einde

Journal of the Minnesota Academy of Science

This paper presents a 2T thermodynamic cycle operating around the critical locus of ethylene. The cycle converts heat energy to work at a rate greater than the Carnot cycle. This energy conversion rate challenges the use of Carnot's thermodynamic efficiency as a foundation for the second Jaw of thermodynamics. The paper discusses the historical development of classical theory and the second law's foundation in logic.

A Center-Unstable Manifold Theorem For Parametrically Excited Surface Waves, Larry Turyn

Mathematics and Statistics Faculty Publications

When fluid in a rectangular tank sits upon a platform which is oscillating with sufficient amplitude, surface waves appear in the ''Faraday resonance.'' Scientists and engineers have done bifurcation analyses which assume that there is a center manifold theory using a finite number of excited spatial modes. We establish such a center manifold theorem for Xiao-Biao Lin's model in which potential flow is assumed but an artificial dissipation term is included in the system of partial differential equations on the free surface. We use interpolation spaces developed by da Prate and Grisvard, establish maximal regularity for a family of evolution …

Hd 12545, A Study In Spottedness, Melissa Hampton, Gregory W. Henry, Joel A. Eaton, Richard A. Nolthenius, Douglas S. Hall

Information Systems and Engineering Management Research Publications

We have solved two sets of light curves of HD 12545 at its epoch of extreme spottedness in 1990-91, one of which coincides with an independent set analyzed recently by Strassmeier and Olah. Even for the huge amplitudes observed, these light-curve solutions did not give reliable determinations of several important spot properties. Specifically, we find that we could obtain acceptable solutions for a wide range of inclination; that spot temperature depends on inclination assumed, falling in the range Delta-T = Tstar - Tspot = 650-1200 K for inclinations of 70-30 deg; that spot latitudes derived from the light curves are …

Strengthening The Foundations Of Outdoor Education, Anderson B. Young, Leo H. Mcavoy

A preface to the journal "Research in Outdoor Education," volume 3 is presented by the authors on behalf of the Coalition for Education in the Outdoors (CEO) Research Committee.

Front Matter, Coalition For Education In The Outdoors (Ceo)

Research in Outdoor Education

The Coalition for Education in the Outdoors initiated a Research Task Force in 1990 with the purpose of supporting the conduct of research in the field and the dissemination of the results. The symposium at Bradford Woods and these proceedings offer evidence of the success of this task force. At the first symposium in 1992, there was general agreement that the symposium be a regular occurrence. The 1994 and 1996 Symposia and these Proceedings are indicators of the Coalition's continued support of research in outdoor education. Information on future events will be available through the Coalition office.

Outdoor Education And Spirituality, Tom Smith

Research in Outdoor Education

The question at hand is that of researching the impact of outdoor recreational and educa­tional experiences on the spiritual development of the individual. I approach that question from the perspective of a facilitator of personal growth who has long advocated the methodolo­gies considered as experiential outdoor/chal­lenge/adventure education.

Outdoor Education And The Schools, Bert Horwood

Research in Outdoor Education

The research reported to gatherings spon­sored by the Coalition for Education in the Out­doors has had relatively little connection with school-based outdoor education. In this paper, I will explore the potentially fruitful interface between education in the outdoors and the schools. The exploration is influenced by the uncertainty of our times, and I have organized this report to reflect two views. One is that the social ferment of the mid-1990s is normal and that we can continue to conduct research in the way that Kuhn (1974) characterized as "normal science." The second view is that the social fab­ric of the …

Person-Place Engagement Among Recreation Visitors, Iris B. Wilson

Research in Outdoor Education

Leaders of groups participating in experien­tial programs in the outdoors, particularly in backcountry expeditions, can increase group management effectiveness and enhance personal benefit to participants by taking into account the various modes in which individuals engage themselves with the physical setting.

Responsible Environmental Behavior: Metaphoric Transference Of Minimum-Impact Ideology, J. Porter Hammitt, Wayne A. Freimund

Research in Outdoor Education

This abstract represents a thesis research project that studied changes in National Outdoor Leadership School (NOLS) students' attitudes, intentions, and behavior, as they pertain to the environment, resulting from participation in NOLS' Wind River Wilderness course. It was hypothesized that an increase in these concerns would result from the metaphoric transference of minimum-impact ideology to daily life. Prominent theories from the fields of social psychology and environmental education relating attitudes, intentions, behavior, and other considerations were incorporated into the theo­retical framework of the study.

Providing An Authentic Wilderness Experience? Thinking Beyond The Wilderness Act Of 1964, William T. Borrie, Joseph W. Roggenbuck

Research in Outdoor Education

Six facets of a wilderness experience are suggested (oneness, humility, primitiveness, timelessness, soli­tude, and care) based on the writings of wilderness philosophers such as Henry David Thoreau and John Muir. In structuring our lessons in wilderness, we could do well to broaden our notion of wilderness be- yond the Wilderness Act.

Ethical Frameworks, Moral Practices And Outdoor Education, Karen M. Fox, Mick Lautt

Research in Outdoor Education

Discoveries and insights from quantum physics and chaos theory help create new metaphors about. ethical frameworks and moral practices in outdoor education. Using concepts such as fractals, fields, and strange attractors, we explore new ways to view research results, scholarly writings, and creative endeavors related to outdoor education. In addition, we evaluate four themes related to the present ethical discourse in outdoor education and sketch new directions for moral practice.

Group Development And Group Dynamics In Outdoor Education, Leo H. Mcavoy, Denise S. Mitten, L. Allison Stringer, James P. Steckhart, Kraig Sproles

Research in Outdoor Education

This paper presents an update of the research on group development and group dynamics in out­door education since the 1992 edition of these Proceedings. The research is presented within the six categories of individual and personal dimensions: group process and structure, group functions and tasks, leadership and power, environmental influences, and the impact of the group on the in­dividual. The paper includes a discussion of pertinent research in the fields of social work, com­munications, and management Specific recommendations are made for future research in outdoor education focusing on group development and dynamics.

Integrating Outdoor Leadership Education Into The Academic Setting, Pamela E. Foti

Research in Outdoor Education

To integrate outdoor leadership education effectively within university academic programs, innovative curricula need to be developed that combine field and classroom work. The goal must be to enable students to understand and assimilate the knowledge base within the classroom and to be able to.apply and show judgment and competence in the field.

A Research Update Of Adventure Therapy (1992-1995): Challenge Activities And Ropes Courses, Wilderness Expeditions, And Residential Camping Programs, H. Lee Gillis, Donna Thomsen

Research in Outdoor Education

n 1992 a review of research in adventure therapy offered a perspective that utilized work in psy­chotherapy as a lens to view the current state of the field. From that review, several recommenda­tions were made to gain respect within the field of traditional mental health. This update examines the recommendations made in 1992 and updates them utilizing research that has taken place in adventure therapy and borrowing liberally from suggestions made for enhancing the field of psy­chotherapy. The article makes the following points. First, the field of adventure therapy must cre­ate a collective document that addresses its accomplishments and effectiveness. …

Interactive Behaviors Between Students And Instructors In The Outdoors, Christine Cashel

Research in Outdoor Education

Research investigating the instructional pro­cess has been conducted in many settings but is still a young science (Rink, 1985). The relation­ships between variables that affect the teaching-­learning process and student achievement have been studied in contemporary educational re­search. Few, if any, studies have focused on the interactive behaviors of instructors and students in the outdoor environment.

The Current Status Of Women's Employment In Outdoor Leadership, T. A. Loeffler

Research in Outdoor Education

The study analyzed women's employment rates from 62 outdoor organizations to determine women's rep­resentation in the outdoor field. Statistical analysis revealed that women were under-represented in outdoor organizations at the executive and management levels using a proportionality standard. Additionally, women reported lower salaries and higher gender-based discrimination occurrences than their male coun­terparts.

"Kind Of In The Middle": The Gendered Meanings Of The Outdoors For Women Students, Karla A. Henderson, Sherry Winn, Nina S. Roberts

Research in Outdoor Education

The purpose of this study was to examine the links between past, present, and future involvement for females and perceptions about whether the outdoors was perceived as a gendered environment Data were collected using five focus group interviews. Several aspects of grounded theory emerged from this study including aspects of exposure to outdoor opportunities as a child, in­volvement in the outdoors as a result of an4 resistance to a gendered society, and contradictions between idealized attitudes and the realities of women's involvement in the outdoors.

The Permanency Of A Specific Self-Concept, Alan N. Wright

Research in Outdoor Education

The Adjective Check List was used to measure a global and a specific self-concept. The results indicate differentiation between the global self and a specific adventure self as mountaineer and a high degree of permanency was found in the specific self at the follow-up thirteen years later.
