Neuroendocrine Reactivity During The Naturalistic Stress Of An Outward Bound Course, Camille J. Bunting, Cynthia Kuhn, Redford B. Williams Jan 1992

Neuroendocrine Reactivity During The Naturalistic Stress Of An Outward Bound Course, Camille J. Bunting, Cynthia Kuhn, Redford B. Williams

Research in Outdoor Education

Recent studies have found that subjects with high hostility propensity have greater catecholamine (CA) and cortisol (Cf) levels during laboratory stressors. The present investigation sought to determine if similar patterns would be found in the naturalistic setting of an Outward Bound experience, and if high versus low aerobic fitness would influence CA and CT levels in this setting. Sixty-six individuals volunteered for the study from participants who had registered for a nine-day 'adult intensive' Outward Bound course. Thirty-one subjects were selected from those who volunteered. The Cook-Medley Hostility Inventory was completed by each subject prior to arriving for their course …

Psychological Rationale For Adventure Therapy With Hospitalized Adolescents, H. Lee Gillis, Alan Williams, Helen Hollis Jan 1992

Psychological Rationale For Adventure Therapy With Hospitalized Adolescents, H. Lee Gillis, Alan Williams, Helen Hollis

Research in Outdoor Education

Inpatient and residential therapeutic programs for adolescents are often fairly generic in format relying heavily on traditional, insight-Oriented approaches to treatment without regard to how the intellectual functioning of the adolescent might impact upon therapeutic effectiveness. This study examined the WISC-R profiles of two treatment populations and presented a theoretical rationale for using adventure based treatment based upon the participants performance on verbal and performance subscales. It is hoped that the article might be used to help justify the implementation of adventure therapy in psychiatric treatment facilities and lead to further research to test the proposed hypotheses.

Outdoor Leadership: A Question Of Vision And Ethics, Karen M. Fox, Leo H. Mcavoy Jan 1992

Outdoor Leadership: A Question Of Vision And Ethics, Karen M. Fox, Leo H. Mcavoy

Research in Outdoor Education

Outdoor education increasingly includes programs for youth-at-risk, multi-cultural groups, battered women, and other special populations. The diversity of such groups and their needs and expectations place additional demands upon the outdoor leader. "Good judgement" on a trip with seniors may not be identical to "good judgement" on a trip with youth-at-risk; group exercises appropriate for young males of color may be inappropriate for women who have been abused. The diverse populations and situations will require outdoor leaders to become more self-aware, reflective, and sensitive to culture, race, and gender differences (Greenleaf, 1970; Shapiro, 1988; Terry, 1988). Resolving conflicts and ethical …

Phenomenological Study Of Wilderness Experience And Human Development, Maurice Legault Jan 1992

Phenomenological Study Of Wilderness Experience And Human Development, Maurice Legault

Research in Outdoor Education

This study is aimed at better understanding the phenomenon of interaction between the individual and the natural environment from a human development perspective. It is a qualitative study focusing on the scientific study of the human experience in a natural environment The main theoretical context for this study is that of phenomenology (Husserl, 1859-1938), from which stems phenomenological psychology, whose founder Giorgi (1931- ) defined it as being the study of phenomena as experienced by enlightened human beings, and the research methods for the study of these phenomena (Giorgi, 1983). The focus is thus the Lebenswelt, which in Husserlian terminology …

The Impact Of Total Employee Participation In An Experience-Based Training And Development Program, Or Corporate Adventure Training Program, On The Corporation's Work Climate, Simon Priest Jan 1992

The Impact Of Total Employee Participation In An Experience-Based Training And Development Program, Or Corporate Adventure Training Program, On The Corporation's Work Climate, Simon Priest

Research in Outdoor Education

Experience-based Training and Development (EBTD) or Corporate Adventure Training (CAT) has had a short history of usage and a long history of problems· with its credibility. Proponents of EBTD/CAT have claimed it was an effective and appropriate way to build teams, develop individuals and improve companies. They stated their case on a moderate collection of personal anecdotes and testimonies. Opponents of EBTD/CAT have claimed it was a sham, like many of the group oriented encounter techniques of the sixties. They cemented their opinion by pointing to a clear lack of research evidence, failing to substantiate the impact of such programs. …

Fire In A Riparian Shrub Community: Postburn Water Relations In The Tamarix-Salix Association Along The Lower Colorado River, S. D. Smith, D. E. Busch Jan 1992

Fire In A Riparian Shrub Community: Postburn Water Relations In The Tamarix-Salix Association Along The Lower Colorado River, S. D. Smith, D. E. Busch

Life Sciences Faculty Research

Higher water potentials in recovering burned salt-cedar (Tamarix ramosissima) relative to unburned plants and the opposite situation in willow (Salix gooddingii) provide evidence that postfire water stress is reduced in the former but not the latter. Similarly, diurnal patterns of stomatal conductance in these taxa are consistent with the existence of more vigor in burned salt-cedar than willow. Plots of water potential and transpiration demonstrate that hydraulic efficiencies may contribute to differences in fire recovery.

Sr-Isotope Record Of Quaternary Marine Terraces On The California Coast And Off Hawaii, Kenneth R. Ludwig, Daniel R. Muhs, Kathleen R. Simmons, James G. Moore Jan 1992

Sr-Isotope Record Of Quaternary Marine Terraces On The California Coast And Off Hawaii, Kenneth R. Ludwig, Daniel R. Muhs, Kathleen R. Simmons, James G. Moore

United States Geological Survey: Staff Publications

Strontium-isotopic ratios of dated corals have been obtained from submerged reefs formed during Quaternary glacial periods off the Hawaiian islands. These data, combined with data from deep-sea sediments, tightly constrain the secular variation of marine 87Sr/86Sr for the past 800,000 yr. Although long-term trends are apparent, no significant (>0.02‰), rapid (<100,000 yr) excursions in 87Sr/86Sr were resolved nor did we observe any samples with 87Sr/86Sr greater than that of modern seawater. Strontium in mollusks from elevated marine terraces formed during interglacial periods on the southern California coast show resolvable and consistent variations in …

The Last Interglacial-Glacial Transition In North America: Evidence From Uranium-Series Dating Of Coastal Deposits, Daniel R. Muhs Jan 1992

The Last Interglacial-Glacial Transition In North America: Evidence From Uranium-Series Dating Of Coastal Deposits, Daniel R. Muhs

United States Geological Survey: Staff Publications

Considerable uncertainty exists as to whether the last interglacial was relatively "short" (~10 ka) or "long" (-20-60 ka), although most investigators generally agree that the last interglacial correlates with all or part of deep-sea oxygen-isotope stage 5. A compilation of reliable U-series ages of marine terrace corals from deposits that have been correlated with isotope stage 5 indicates that there were three relatively high sea-level stands at ca 125-120 ka, ca. 105 ka, and ca. 85-80 ka, and these ages agree with the times of high sea level predicted by the Milankovitch orbital-forcing theory. At a number of localities, however, …

Recent Improvements Of Water Quality And Biological Indicators In Hillsborough Bay, A Highly Impacted Subdivision Of Tampa Bay, Florida, J.O. R. Johansson, R. R. Lewis Iii Jan 1992

Recent Improvements Of Water Quality And Biological Indicators In Hillsborough Bay, A Highly Impacted Subdivision Of Tampa Bay, Florida, J.O. R. Johansson, R. R. Lewis Iii

Reports

Hillsborough Bay, the eastern uppermost section of the Tampa Bay system, is surrounded by a large metropolitan complex, supports extensive industrial activity, and serves as a major shipping port of fertilizer products. The Bay was determined to be highly eutrophic during the late 1960s. The City of Tampa's primary sewage treatment plant and runoff from fertilizer industry activities were considered as the major sources of excessive nutrient loading. Loadings form both these sources have been reduced during the last 10 years, which has probably been the leading cause of improved water quality parameters such as water clarity, dissolved oxygen, and …

13.2.14. Management Of Habitat For Breeding And Migrating Shorebirds In The Midwest, Jan Eldridge Jan 1992

13.2.14. Management Of Habitat For Breeding And Migrating Shorebirds In The Midwest, Jan Eldridge

Waterfowl Management Handbook

Shorebirds have always relied on the extensive network of natural wetlands from Texas to North Dakota. This network has now been fractured by wetland drainage and agriculture to the point where suitable wetlands are absent in much of the Midwest. Habitat loss and the resulting risk of population decline highlight the importance of management of shorebirds on refuges, hunting clubs, and preserves for both breeding and migrating species.

Because shorebirds, like waterfowl, depend on wetlands throughout the year, the loss of natural wetlands in the Midwest poses a real threat. Unfortunately, shorebirds are slow to recover from population declines caused …

13.4.5. A Technique For Estimating Seed Production Of Common Moist-Soil Plants, Murray Laubhan Jan 1992

13.4.5. A Technique For Estimating Seed Production Of Common Moist-Soil Plants, Murray Laubhan

Waterfowl Management Handbook

Seeds of native herbaceous vegetation adapted to germination in hydric soils (i.e., moist-soil plants) provide waterfowl with nutritional resources including essential amino acids, vitamins, and minerals that occur only in small amounts or are absent in other foods. These elements are essential for waterfowl to successfully complete aspects of the annual cycle such as molt and reproduction. Moist-soil vegetation also has the advantages of consistent production of foods across years with varying water availability, low management costs, high tolerance to diverse environmental conditions, and low deterioration rates of seeds after flooding.

The amount of seed produced differs among plant species …

Distribution, Abundance, And Behavior Of The Cownose Ray, Rhinoptera Bonasus (Mitchill 1815), In Lower Chesapeake Bay, Robert A. Blaylock

Dissertations, Theses, and Masters Projects

Aspects of the ecology of the cownose ray, Rhinoptera bonasus, in the lower Chesapeake Bay and its tributaries were studied using aerial surveys, biotelemetry, and examination of stomach contents. The Chesapeake Bay was surveyed by airplane during 1986-1989, to examine the distribution of cownose rays and estimate their abundance using line transect methods. Cownose rays resided in Chesapeake Bay throughout the summer months, entering in early June and emigrating in late September. They were usually absent, or nearly so, by late October. Mean monthly abundance ranged from none present in May and November, to a September average of 9.3 &\cdot& …

Ontario's Blue Box As An Agent Of Change, Robert Nathaniel Burgess Jan 1992

Ontario's Blue Box As An Agent Of Change, Robert Nathaniel Burgess

Theses and Dissertations (Comprehensive)

Ontario's blue box has elicited strong arguments from observers on both sides of a debate regarding the recycling programme‘s promotion of social change in the province. Both supporters and critics agree on our eventual need to change from a consumer to a conserver society through the 3Rs of waste management (reduce. reuse. recycle). but they disagree on whether the blue box programme ultimately encourages this change. Disagreement also exists regarding the means to achieving change. With supporters of the blue box approach favouring working within the system whereas critics tend to favour a more radical approach. Practical criticisms concern the …
