Animal trainers working in scent detection programs are responsible for arranging training contingencies as well as for observing and recording animal behavior. We provided behavioral skills training (BST) to animal trainers working with scent detection rats to improve the treatment integrity of scent‐detection research sessions. We evaluated the trainers' behavior at baseline and during the sequential introduction of each component of BST (instructions, modeling, and feedback). We observed incremental improvements in treatment integrity with the introduction of each BST component. Posttraining probes revealed that these improvements were sustained at least 3 weeks post‐BST. As the trainers' behavior was modified during BST, we observed decrements in measures of rat performance. We discuss the nature of these interactions and their implications for the use of BST in scent detection research and in situations in which intervention with one party produces concomitant effects on the behavior of another. 相似文献

Stronger beliefs in human supremacy over animals, and stronger perceived threat posed by vegetarianism to traditional practices, are associated with stronger speciesism and more meat consumption. Both variables might also be implicated in the moral exclusion of animals. We tested this potential in a 16-month longitudinal study in the USA (N = 219). Human supremacy showed longitudinal effects on the moral exclusion of all animals. Vegetarianism threat only predicted moral exclusion of food animals (e.g., cows and pigs), and, unexpectedly, appealing wild animals (e.g., chimps and dolphins). These findings demonstrate the importance of both human supremacy and perceived threat in explaining moral exclusion of animals and highlight potential paradoxical negative consequences of the rise of vegetarianism. 相似文献

The paper tries to provide an alternative to Hempel’s approach to scientific laws and scientific explanation as given in his
D-N model. It starts with a brief exposition of the main characteristics of Hempel’s approach to deductive explanations based
on universal scientific laws and analyzes the problems and paradoxes inherent in this approach. By way of solution, it analyzes
the scientific laws and explanations in classical mechanics and then reconstructs the corresponding models of explanation,
as well as the types of scientific laws appearing in it. Finally, it compares this reconstruction with the approaches of J.
Woodward and C. Hitchcock, C. Liu and with the views of M. Thalos on analytic mechanics.

Six “divine conjectures” frame the place of Theóne (The One to Whom we pray) in the creation of our universe and for its continuing development in five subsequent stages into a loving universe. The first stage, the cosmological universe, establishes the laws of nature, understood by scientists as the “standard model”. The second stage introduces life and death into the universe by a process we are only now beginning to understand. Stage 3 requires certain life forms to become conscious with a subset of those life‐forms acquiring language that results in that subset becoming self‐conscious. The next stage, Conjecture 4, identifies certain persons who become addicted to learning in their unrelenting effort to learn as much of what can be known as possible. The fifth conjecture requires individual persons to act as agents of Theóne in achieving Conjecture 6—a universe that is both loving and lawful. During the course of the exposition subsidiary discussions of the concepts of conjecture and hypothesis explicate the function of each in the advancement of knowledge and understanding. There are brief discussions of prayer and purpose in relation to the Divine. 相似文献

Twenty domestic horses (Equus caballus) were tested for their ability to rely on different human gesticular cues in a two-way object choice task. An experimenter hid food under one of two bowls and after baiting, indicated the location of the food to the subjects by using one of four different cues. Horses could locate the hidden reward on the basis of the distal dynamic-sustained, proximal momentary and proximal dynamic-sustained pointing gestures but failed to perform above chance level when the experimenter performed a distal momentary pointing gesture. The results revealed that horses could rely spontaneously on those cues that could have a stimulus or local enhancement effect, but the possible comprehension of the distal momentary pointing remained unclear. The results are discussed with reference to the involvement of various factors such as predisposition to read human visual cues, the effect of domestication and extensive social experience and the nature of the gesture used by the experimenter in comparative investigations. 相似文献

The paper argues against the very commonly held view that whenever a substance may be said to be the cause of something, a
fuller and metaphysically more accurate understanding of the situation can always be obtained by looking to the properties
in virtue of which that substance was able to bring about the effect in question. Paul Humphreys’ argument that when a substance
is said to have produced an effect, it always turns out to be an aspect or property of that substance which brought about
the effect in question is examined and criticized; it is argued that it is based on an illegitimate application of Mill’s
Methods of Difference and Agreement to the case. Mill’s methods, it is suggested, are methods of empirical, not of ontological
enquiry. The paper then turns to examine an argument by Mele which appears to depend on a structurally rather similar assumption
that if there is nothing about a subject which could explain why she does one thing rather than another, it cannot really
be up to that subject which thing occurs. It is suggested that, too, the inference is faulty, and that once it is rejected,
one common objection to libertarianism—the argument from luck—might be more readily met. 相似文献
