Headache is a common symptom in primary care about which surprisingly little is known. Over a 14-month period 3847 patients making 4940 consecutive visits for headache to 38 primary care practices in the USA and Canada were studied. The clinical characteristics of patients, as well as the diagnostic and therapeutic strategies employed by their doctors, were examined. Visits for headache represented 1.5% of all visits during this period. Most patients (72.0%) made only one visit, and nearly half of the headaches reported were new. Only a small number of patients (3.0%) received a computerized tomographic scan; other investigations were used …

Sensory Modulation Of Juvenile Play In Rats, Stephen M. Siviy, Jaak Panksepp Jan 1987

Sensory Modulation Of Juvenile Play In Rats, Stephen M. Siviy, Jaak Panksepp

Psychology Faculty Publications

A series of experiments was conducted to determine the extent to which somatosensory stimulation is necessary for the elaboration of juvenile play in rats. Anesthetization of the dorsal body surface of juvenile rats with xylocaine reduced the frequency of pinning, an indicator variable for play, by 35% to 70%, while motivation to play, measured by dorsal contacts, an index of play solicitation, remained largely intact. These data suggest that dorsal body surface anesthetization impairs the ability of juvenile rats to perceive and/or respond to playful gestures. When untreated animals were paired with xylocaine-treated animals, the xylocaine-treated animals consistently pinned the …


Africa's Conservation For Development, Norman Miller, Rodger Yeager Jan 1987

Africa's Conservation For Development, Norman Miller, Rodger Yeager

Dartmouth Scholarship

Africa's modern dilemma is a "floor of life" issue. Resource loss, environmental degredation, and overpopulation have reduced many people to the lowest subsistence levels in living memory. By all accounts a biologically diverse wonderland, Africa is quite literally the last place on earth for many plant and animal species. Yet the basis of human and nonhuman survival has become threatened in many areas because of soil and water depletion, deforestation, and desertification. Human mistakes are invariably cited as among the basic causes of these tragedies.


Forest Conservation In Nepal: Encouraging Women's Participation, Augusta Molnar Jan 1987

Forest Conservation In Nepal: Encouraging Women's Participation, Augusta Molnar

Poverty, Gender, and Youth

This issue of SEEDS focuses on ways in which women have been involved in a government forest conservation and restoration program in Nepal. As is common with many large-scale projects with a general impact, women were not a direct focus of the project's original design. As activities got underway, however, both the Nepali staff and their expatriate colleagues quickly realized that the direct involvement of women was crucial to the success of the project's participatory strategy. Over the initial five years, 1980 to 1985, a number of approaches to addressing women's needs and generating their active participation were tried. The …


An Inventory And Condition Survey Of Rangelands In The Carnarvon Basin, Western Australia, A L. Payne, G F. Spencer, P J. Curry Jan 1987

An Inventory And Condition Survey Of Rangelands In The Carnarvon Basin, Western Australia, A L. Payne, G F. Spencer, P J. Curry

Technical Bulletins

The inventory and condition survey of rangelands in the Carnarvon Basin, undertaken by the Department of Agriculture and Food, Western Australia (DAFWA) between 1980 and 1982, describes and maps the natural resources of the region’s pastoral leasehold land. This survey report provides a baseline record of the existence and condition of the natural area’s resources, to assist with the planning and implementation of land management practices. The report identified and described the condition of soils, landforms, vegetation, habitat, ecosystems, and declared plants and animals. It also assessed the impact of pastoralism and made land management recommendations. The area surveyed covers …

Structural Analysis Of The Pacific Northwest Lumber And Plywood Industries, James G. Strathman, Anthony M. Rufolo, M. Hossein Haeri Jan 1987

Structural Analysis Of The Pacific Northwest Lumber And Plywood Industries, James G. Strathman, Anthony M. Rufolo, M. Hossein Haeri

Center for Urban Studies Publications and Reports

The lumber and plywood industries in the Pacific Northwest were particularly affected by the 1979-1982 construction recession. A subsequent recovery in output has occurred, but employment levels have remained relatively depressed. The potential for a planned reduction in the amount of timber sold from the national forests in the region also exists, giving rise to some uncertainty about the future prospects for these industries. This paper identifies the major structural factors affecting the performance of lumber and plywood producers in the region. It then proceeds to develop and simulate a set of alternative scenarios covering the 1986-1990 period to examine …
