Two pigeons were trained on a six-key modified oddity-from-sample procedure. The stimuli were olor pictures of birds, butterflies, and human faces. Initially, the third peck on the sample key which presented one of three different bird pictures) lit only one comparison key. Every three dditional pecks on the sample illuminated another comparison key. Fifteen sample pecks produced he maximum of five comparison stimuli. A peck on the comparison key that presented the non-atching bird picture produced grain. Pecks on matching keys turned off all the comparison keys nd repeated the trial. The birds learned to peck each sample until the non-matching comparison timulus was produced, and then to peck that key. After acquisition (70%–90% accuracy), the hree bird stimuli were replaced by a new set of three bird pictures. Subsequent phases provided ew sets of bird, butterfly, and human face stimuli. Both birds showed transfer of oddity learning o the novel samples. The data suggest that the birds may have been engaging in conceptual-type oddity learning, rather than learning discrete five-key discriminations or a series of two component chains.  相似文献

AIMS AND OBJECTIVES: Access to health information is important for the well-being of people living in the community after spinal cord injury (SCI). In order to design appropriate information interventions, it is critical first to understand the information sources typically used. The goal of this study therefore is to identify the information-seeking practices of this group. SAMPLE AND METHODS: A sample of 207 individuals living in the community following traumatic spinal cord injury were surveyed regarding their ongoing information needs and practices for seeking information. RESULTS: The results reveal that respondents have unmet information needs, despite the fact that they typically access information through a variety of channels. SCI specialists are the most commonly used source, although they are viewed as relatively inaccessible. By contrast, the Internet (used by a relatively high proportion of respondents) is viewed as comparatively accessible, although there are some concerns about the quality of information found there. CONCLUSIONS: These survey results point to the need for an information source that is accessible and delivers high quality information. Although respondents use a variety of information sources, none meets this ideal profile. Information professionals should consider this gap in the design of information interventions.  相似文献

The cost of prenatal care in a private nurse-midwifery practice was examined using the activity-based costing system. Findings suggest that the activities of the nurse-midwife (the health care provider) constitute the major cost driver of this practice and that the model of care and associated, time-related activities influence the cost. This pilot study information will be used in the development of a comparative study of prenatal care, client education, and self care.  相似文献

There is an ever increasing interest in the development of within firm mechanisms to augment the transfer of intellectual property from laboratory environments to commercialization. The Federal Laboratory System is an example of where policy has recently been developed to strengthen their efforts in the technology transfer process. Entrepreneurial separation to transfer technology programs (ESTT) represent one mechanism that laboratories have to assist with the transfer of intellectual property across boundaries, especially in situations where initial efforts at commercialization have failed. However, no formal research exists on the effectiveness of these programs as a boundary spanning device. This work is based on a preliminary study in the ESTT domain placed in the technology transfer body of literature. In depth interviews were conducted with four organizations, along with a review of more than fifty organizational policies in order to develop an initial framework of ESTT programs. We introduce the concept of ESTT programs and discuss how inventor motivations and characteristics of the invention itself might influence the success of ESTT.  相似文献

Despite strenuous attempts made by the New Labour government in the UK to progress towards its goal of eradicating child poverty by 2020, educational outcomes for disadvantaged children remain depressed compared to those of more advantaged children. The fact that children from poorer socio‐economic backgrounds are at much greater risk of language delay, which is a key predictor of poorer educational outcomes, indicates that there is a fundamental need to enhance the language abilities of these children in their early years in order to improve educational progress. This paper discusses the extent to which two new major UK policy initiatives may impact on this situation, namely the introduction of the Early Years Foundation Stage, a new curricular framework for children aged from birth to five, and the development of the Early Years Professional role, seen as key to the implementation of this framework. The discussion concludes that due to insufficiently rigorous conceptual underpinnings, especially in the area of language and communication, these innovations seem unlikely to deliver the type of language‐enriched preschool environments necessary to enhance the linguistic capabilities of the poorest children in UK society.  相似文献

ABSTRACT

In a prior edition of this study, we examined whether the established online communication studies indexes—Communication Abstracts, ComIndex, and ComAbstracts—provided a good avenue of access to the journal literature that researchers in the field cite and whether, where the current journal literature was concerned, that avenue of access might be equal or superior to that provided by large, multisubject online indexes. In this iteration of the study, we similarly address EBSCO's new product for communication studies, Communication & Mass Media Complete.  相似文献
