The Role Of Adventitious Reinforcement In Operant Discrimination, Alan Kamil, John W. Davenport Jan 1968

The Role Of Adventitious Reinforcement In Operant Discrimination, Alan Kamil, John W. Davenport

Avian Cognition Papers

Rats were trained in 2 SD-SΔ discrimination experiments in which the effects of an SD-postponement contingency during SΔ and temporal regularity of SΔ duration were assessed. Experiment I showed that discrimination is markedly facilitated by the presence of an SD-postponement contingency of either fixed or variable duration. Experiment II showed that variable-duration SΔ periods in a noncontingent schedule can also greatly enhance formation of an operant discrimination. These effects were attributed to differences in the probability of adventitious reinforcement of SΔ behavior by SD events.

Some Interpretations Of A Map On Minnesota Sawmilling, Lyda Belthuis Jan 1965

Some Interpretations Of A Map On Minnesota Sawmilling, Lyda Belthuis

Journal of the Minnesota Academy of Science

Sawmilling in Minnesota started about the time of settlement and, until 1870, mainly consisted of small mills located in the southern half of the state. Mills along the Mississippi River were mainly in urban centers while the remainder were scattered and associated with the clearing of the land and the meeting of the needs of local communities. After 1870, mills become larger. Many were constructed in northern Minnesota. All used forests in the northern port of the state and reduced them so greatly that, by 1920, the mills closed and were replaced by portable sawmills.

A Classification For Forestry Literature, Faculty Of The Yale Forest School Feb 1912

A Classification For Forestry Literature, Faculty Of The Yale Forest School

Yale School of the Environment Bulletin Series

The following classification for forestry literature has been prepared by the Faculty of the Yale Forest School for use in its library. It is published to supply the demand for a simple and comprehensive classification that is adapted to any library system. The work was begun about one year ago and included a study of all available data on the subject. A tentative outline was submitted to prominent members of the profession from whom helpful suggestions were received.

The subject has been divided into nine parts of approximately equal importance. The secondary divisions also have been limited to nine and …
