Functional Explanation And Metaphysical Individualism, Justin Schwartz

Justin Schwartz

A number of (present or former) analytical Marxists, such as Jon Elster, have argued that functional explanation has almost no place in the social sciences. (Although the discussion is framed in terms of a debate among analytical Marxists, the point is quite general, and Marxism is used for illustrative purposes.) Functional explanation accounts for what is to be explained by reference to its function; thus, sighted organism have eyes because eyes enable them to see. Elster and other critics of functional explanation argue that this pattern of explanation is inconsistent with "methodological individualism," the idea, as they understand it, that …

White Plastic Flags Repel Snow Geese, J. Russell Mason, Larry Clark, N. Jay Bean

Larry Clark

The effectiveness of white flags as visual repellents to snow geese (Chen caerulescens) was evaluated. Twelve fields, each 10.12 ha (25 acres) in area, with snow goose damage, were located and proximity was used to create six pairs. Within each pair, one field was selected randomly for treatment (one white plastic flag per acre) and the other served as a control. At 7-day intervals for SV2 weeks, mean vegetation length and mean percentage vegetative cover were estimated for all fields. The results showed that grazing damage was significantly reduced in fields with flags. It is concluded that white plastic flags …

Development Of Chemosensory Attractants For White-Tailed Deer (Odocoileus Virginianus), J. Russell Mason, N. Jay Bean, Larry Clark

Larry Clark

White-tailed deer (Odocoileus spp.) overpopulate many areas of the United States. Browse damage to agricultural crops, forest regeneration and landscaping can be severe. Human and animal health also arc threatened by Lyme disease, which is spread by the deer tick (Ixodes dammini). Although sterilants to reduce and/or slow the growth of deer populations and vaccines against Lyme disease may soon become available, efficient and economical techniques to inoculate large numbers of deer have not been developed. Oral baits represent one promising possibility. In experiment 1, salt blocks and several olfactory lures were evaluated as potential lures for use in deer …

Effects Of Predator Size And Female Receptivity On Courtship Behavior Of Captive-Bred Male Guppies, Given Harper, Kristin Braun

Given Harper

The effects of predator size and female receptivity on the courtship behavior of captivebred male guppies (Poecilia reticulata) were investigated. Male guppies exhibited riskreckless courtship behavior in that they did not decrease the amount of time spent performing visually conspicuous sigmoid displays and increase the frequency of attempted forced copulations when large predatory fish were present. Female receptivity (i.e., virgin or non-virgin females) also had no effect on male courtship behavior.
