The major purpose of this study was to compare the occurrence
of "delinquent" and "non-delinquent" responses and their contingent
social reinforcements during informal cottage peer interaction at a
training school for adolescent delinquent girls. The following hypotheses were tested: (1) The occurrence of delinquent responses exceeds
the occurrence of non-delinquent...
Trawl cables are wire ropes which corrode under the influence of
seawater depending on fishing habits.
Information about the problem was obtained from the preceeding
work by Robert D. Malloch, and from contacts with the fishermen.
Statistical data about fishing boats and fishing habits on the Pacific
Northwest Coast are...
Extensive morphological and growth habit variations have been
reported for bitterbrush (Purshia tridentata), a widespread western
shrub frequently used in range revegetation projects. Hybridization
of this species occurs with cliffrose (Cowania stansburiana) at the
point of their overlapping range in Utah and is believed to be
responsible for expression of...
Appendicularians are ubiquitous marine grazers that use tangential filtration to collect micron and submicron prey. The food-concentrating filter (FCF) is the primary determinant of appendicularian prey selectivity, but the precise means by which it concentrates and conveys particles to the pharyngeal filter remain poorly understood. We used high-speed videography to...
In the context of the restriction of production, French agriculture modifies its activities by developing multifunctionality. This concept translates the fact that, beyond the saleable production of agricultural and food processing products, the agricultural activity fulfills other functions: economic, social, environmental. Multifunctionality of agriculture is implemented in a number of...
While French marine fisheries must cope with increasing difficulties, the concept of
multifunctionality of fisheries (as previously observed in agriculture) is emerging
through a diversification of activities. Indeed, fishers resort to alternatives in order to
sustain their activity by calling on new ways to interact with environment, institutional
players, scientists,...
