Spot observation: Advantages and disadvantages for household time use research

The spot observation method of estimating time use is described in this article. Procedures for using this method in developing countries, where household activities are relatively easily observed, are contrasted with procedures used in countries characterized by very private living units and highly separated employment, educational, and household settings. Characteristics of various methods for collecting time use data are compared so that researchers can evaluate the trade-offs they can expect from selecting a particular method. A case example of using the spot observation method in a study of women's household and agricultural activities in the Njoro Region of Kenya is presented.Her research interests are household time allocation and women's economic status in developing countries.Her research interests include the time allocation of rural women and women in international development. She received her Ph.D. from the University of Illinois in 1995.The study of women's and children's time use reported in this paper was supported in part by the Center for African Studies, University of Illinois at Urbana-Champaign and by the Office of the Deputy Vice Chancellor for Academic Affairs, Egerton University, Njoro, Kenya.

Annual and seasonal habitat use of Columbian black-tailed deer in urban Vancouver, Washington

We investigated habitat use of Columbian black-tailed deer in urban Vancouver, Clark County, Washington, at 3 spatial scales: (1) placement of the annual home range within the landscape mosaic, (2) annual and seasonal locations of deer within the annual home range, and (3) short-term use of critical habitats (fawning areas) within seasonal ranges. Annual home range sizes of deer were 162 ha (SD = 133; 95% minimum convex polygon; MCP) and 266 ha (SD = 228; 95% adaptive kernel; AK) for does, and 756 ha (SD = 290; MCP) and 1,235 ha (SD = 382; AK) for bucks. Home range composition of does did not differ from the study area; home ranges of bucks contained more Natural ecological land-use cover types (ELUs) than did the study area. Within home ranges, both does and bucks used Natural ELUs more often than expected by their occurrence in the home range, both annually and seasonally. During the fawning season, does were also found in Natural ELUs more often than expected. Clark County-designated habitat corridors differed from both the study area and deer home ranges in habitat composition, primarily by containing more Natural and other undeveloped ELUs. Deer were located in habitat corridors more than expected. Deer in urban areas appear to use undeveloped habitat types for security. Management that maintains Natural ELUs, such as establishment of wildlife corridors, can provide important habitat components for black-tailed deer in urban habitats.
