I review literature on four different approaches to the study of traditions in animals: observation of free-living animals,
laboratory experiment, armchair analysis, and field experiment. Because, by definition, a tradition entails social learning
of some kind, it is difficult, perhaps impossible, to establish that a behavior is in fact traditional without knowledge of
how it develops. Observations of free-living animals often provide strong circumstantial evidence of a tradition. However,
even in the view of several researchers who have studied possibly traditional behaviors in natural populations, observation
alone has not proven sufficient to show that social learning contributes to development of behaviors of interest. The relevance
of laboratory experiments to the understanding of the development of behaviors in free-living animals is always open to challenge.
Armchair analyses of field data can produce interesting hypotheses but cannot test them. Field experiments to determine how
behaviors of interest develop in population members provide a promising way forward. 相似文献

A nationwide survey of county departments of social services revealed a need for medical services and consultation to child protection units. Over 92% of the 84 counties surveyed stated they had a problem meeting their medical needs and would be willing to hire a physician assistant as medical consultant to their county's child protection team. No county refused to consider a physician assistant, but 7% felt their medical requirements were being met. Needs the counties most commonly identified were providing parent education/anticipatory guidance (69%), interviewing (65.5%), interpreting medical information to a multidisciplinary child protection team (58.3%), review of medical records (45.8%), and physical examinations (42.9%). Over 17% of the counties had money to fund a full-time physician assistant, and over 60% of the counties could provide a partial salary, with 70.5% willing to share a salary with adjacent counties and 76.9% with the county's public health department. 相似文献

The Regional Medical Library program of the Dana Medical Library (Burlington, Vermont) is described. Practical problems of a regional program are discussed. A plea is made for providing regional service, however little or much, without waiting for surveys and large grants. 相似文献

Product reviews have become an important resource for customers before they make purchase decisions. However, the abundance of reviews makes it difficult for customers to digest them and make informed choices. In our study, we aim to help customers who want to quickly capture the main idea of a lengthy product review before they read the details. In contrast with existing work on review analysis and document summarization, we aim to retrieve a set of real-world user questions to summarize a review. In this way, users would know what questions a given review can address and they may further read the review only if they have similar questions about the product. Specifically, we design a two-stage approach which consists of question selection and question diversification. For question selection phase, we first employ probabilistic retrieval models to locate candidate questions that are relevant to a given review. A Recurrent Neural Network Encoder–Decoder is utilized to measure the “answerability” of questions to a review. We then design a set function to re-rank the questions with the goal of rewarding diversity in the final question set. The set function satisfies submodularity and monotonicity, which results in an efficient greedy algorithm of submodular optimization. Evaluation on product reviews from two categories shows that the proposed approach is effective for discovering meaningful questions that are representative of individual reviews. 相似文献

The New Faces of Fairness 总被引:1,自引:0,他引:1
For most of the 20th century, measurement professionals paid little interest to item and test fairness. A confluence of events in the late 1960s and early 1970s led to an intense interest in fairness issues among measurement professionals. In spite of more than 30 years of effort, there is still no generally accepted definition of fairness with respect to testing and no measure that can prove or disprove the fairness of a test. To advance the fairness of tests, measurement professionals must pay more attention to reducing group differences at the design stage of test development, to providing all examinees an opportunity to demonstrate their knowledge and skills, to deterring test misuse, and to accommodating differences among individuals. 相似文献
