Influence of changing grouse density and forest attributes on the occupancy of a series of potential territories by male ruffed grouse

Abstract: The history of occupancy of 117 territories established by male ruffed grouse (Bonasa umbellus) on a 700-ha study area in southwestern Alberta was studied over 11 years in relation to changing density of the grouse and attributes of the surrounding forest. The pattern of use of territories varied from continuous occupancy by a series of different birds over as many as 11 years to sporadic occupancy for as little as one season. These two extremes differed in that continuously occupied territories possessed numerous acceptable display sites, were located towards the center of clumps of territories, and hosted long-lived birds. By contrast, sporadically occupied territories possessed few acceptable display sites, tended to be located at the periphery of clumped territories, and hosted short-lived birds. Although the status of the vegetation around the display sites within the territory was a major factor influencing its occupancy, social interactions among the grouse also appeared to influence the history of...

Fire casualties and their relation to fire company response distance and demographic factors

Allocating Building Inspection Manpower for Fire Prevention

Abstract: This paper concerns the analysis of two basic planning problems inherent in the building inspection operations of municipal fire prevention bureas. These problems are 1 how often to inspect each type occupancy in each area of the city, and 2 how to divide the city into “area-of-responsibility” districts, with one district for each inspector. The problems are interrelated and are represented in one model. Formulation of the model is based on the operations of the Atlanta, Georgia, Fire Prevention Bureau. The model constitutes a “controllable” analogue to the political redistricting problem. A solution procedure is presented which is a modification of the Hess and Weaver redistricting algorithm. Application of the model and solution procedure to Atlanta is given. Preliminary results indicate an improvement in districting over current practices.

An Analysis of Black Occupancy of Mobile Homes

Abstract: Mobile homes represent one potential source of new housing for low-income populations. Current data show that this type of housing has become in creasingly attractive to households within the $5,000–10,000 income range. Given that black family incomes are generally lower and housing conditions poorer compared to whites, we would expect that levels of black occupancy of mobile homes would be relatively high. This research examines these levels of black occupancy in mobile homes for twelve states and, taking into account important social, economic, and demographic variables affecting the probability of living in a mobile home, generates an expected level of occupancy for blacks. Actual levels of occupancy are found to range from 4 to 45 percent of these expected levels, indicating a severe under representation of black households in this form of low income housing. Two general explanations for this under representation are discussed: differences in housing preferences between blacks and whites and ...
