Balloon logging with the inverted skyline

There is a gap in aerial logging techniques that has to be filled. The need for a simple, safe, sizeable system has to be developed before aerial logging will become effective and accepted in the logging industry. This paper presents such a system designed on simple principles with realistic cost and ecological benefits

Development of the Centralized Storm Information System (CSIS) for use in severe weather prediction

The centralized storm information system is now capable of ingesting and remapping radar scope presentations on a satellite projection. This can be color enhanced and superposed on other data types. Presentations from more than one radar can be composited on a single image. As with most other data sources, a simple macro establishes the loops and scheduling of the radar ingestions as well as the autodialing. There are approximately 60 NWS network 10 cm radars that can be interrogated. NSSFC forecasters have found this data source to be extremely helpful in severe weather situations. The capability to access lightning frequency data stored in a National Weather Service computer was added. Plans call for an interface with the National Meteorological Center to receive and display prognostic fields from operational computer forecast models. Programs are to be developed to plot and display locations of reported severe local storm events

Visible flux variations across finite clouds

A radiative transfer model developed to computer visible flux variations across and within finite clouds of varying shapes is described. The technique has much of the versatility of Monte Carlo models, as well as the speed of the analytical finite cloud models

Scotch Pine Deterioration in Michigan Caused by Pine Root Weevil Complex

Pine root tip weevil, Hylobius rhizophagus, and pine root collar weevil, H. radicis, attack certain Scotch pine stands simultaneously causing more mortality than expected from either insect alone. Recommendations for curtailing this insect complex include favoring red pine, planting Scotch pine far from brood sources, and avoiding stump culture of Christmas trees

An investigation of surface albedo variations during the recent sahel drought

Applications Technology Satellite 3 green sensor data were used to measure surface reflectance variations in the Sahara/Sahel during the recent drought period; 1967 to 1974. The magnitude of the seasonal reflectance change is shown to be as much as 80% for years of normal precipitation and less than 50% for drought years. Year to year comparisons during both wet and dry seasons reveal the existence of a surface reflectance cycle coincident with the drought intensity. The relationship between the green reflectance and solar albedo is examined and estimated to be about 0.6 times the reflectance change observed by the green channel

Michigan\u27s Cooperative Forest Pest Management Program, A Team Approach to Improving Forest Management

A forest management team was organized in the late 1970\u27s by cooperative efforts of Michigan\u27s universities. the Michigan Department of Natural Resources, and the USDA Forest Service.The goals were to devise new technologies, transfer available technology, and service and management alternatives to forest land managers in Michigan. The program throughout has emphasized forest management rather than pest management for prevention and control of pests. Dissemination of pest management information has been of importance and new research results have gone directly to land managers for immediate use. The team participates in forest compartmental reviews and helps prescribe management plans for land parcels, thus providing for preventative pest management. Services and management recommendations are provided mostly through forest pest specialists located in the field. They feed back results and problems to researchers and extension specialists of the team for further input. Preventive management information used by by local managers in recent years has nearly paid the cost of the program. Plans are to broaden the team effort by cooperating with organizations and in adjacent states through a computer network system and by other means

Representative bureaucracy: does female police leadership affect gender-based violence arrests?

Representative bureaucracy theory postulates that passive representation leads to active representation of minority groups. This article investigates the passive representation of female police officers at leadership levels and the active representation of women vis-a-vis gender-based violence arrest rates in the UK. Much of the extant research on representative bureaucracy is located at street level, with evidence showing that discretionary power of minority bureaucrats can lead to active representation. This article is focused on leadership levels of a public bureaucracy. The empirical research is based upon a panel dataset of female police officers as an independent variable and gender-based violence arrest rates as a dependent variable. The analysis reveals that there is little evidence of active representation of women by female police leadership

Life History and Some Habits of a Larch Moth, \u3ci\u3eParalobesia Palliolana\u3c/i\u3e (Lepidoptera: Tortricidae), in Michigan

(excerpt) Insect injured shoot tips were discovered in the fall of 1971 on larch (Larix spp.) in a mixed larch provenance plating in Shiawassee County, Michigan. Tortricid larvae collected later from them were reared to maturity and identified as Paralobesia palliolana (McDunnough 1938). McDunnough (1938) described this species as Polychrosis palliolana from insects taken in flight but without definitely associated hosts. The holotype he designated was collected at Milford, Nova Scotia; other specimens he examined were from Quebec and Ottawa, Canada
