Rats were trained to leverpress for food and subsequently exposed to either arithmetic series or random variable-interval reinforcement schedules. Adjunctive drinking developed in all subjects exposed to arithmetic variable-interval reinforcement, but did not develop in six of the eight animals trained on the random schedule. The results suggest that adjunctive drinking is the result of an interaction between the tendency of rats to drink after eating and the ability of locally low probabilities of reinforcement within schedules to induce conditioned behavioral states. 相似文献

There is now widespread recognition that digital technologies, particularly portable hand held devices capable of Internet connection, present opportunities and challenges to the way in which student learning is organized in schools, colleges and institutions of higher education in the 21st Century. Traxler, Journal of the Research Centre for Educational Technology, 6(1), 3–15 (2010) suggests such devices are pervasive and ubiquitous, conspicuous and unobtrusive, noteworthy and taken-for-granted with everyone typically owning one, using one and often having more than one. As a consequence it has been argued that the availability of such devices, controlled mainly by the student and not the teacher, has the potential to change the traditional dynamics and pedagogical patterns of the learning environment (Burden et al. 2012). Education institutions, however, typically remain organized around spatial and temporal considerations such as buildings, timetables, calendars and internal structures which are designed to classify and manage students. In the case study reported here students and faculty teaching staff from the College of Education in the Kuwait University were surveyed in order to assess their access to such technologies, their capability to use them effectively in support of achieving planned learning outcomes and the implications for change that could emanate from such findings. 相似文献

Too Much,Too Young? An Analysis of the Key Stage 3 National Literacy Strategy in Practice 总被引:1,自引:0,他引:1
Neil Allen 《English in Education》2002,36(1):5-15
This article was first drafted after I worked for 14 weeks last year in a school that was piloting the National Literacy Strategy at Key Stage 3. I now work in another school delivering the full published Strategy to Year 7. In this article, I explore the contradictions inherent in the Strategy in attempting to develop the English and literacy skills of Key Stage 3 pupils. Ultimately, my argument is that the educational benefits of this teaching to objectives is at odds with some of the deeper aims of the Strategy and of English teaching, and that the constant assessment involved puts too much pressure on our youngsters at an age when they should be concentrating on social development as people. 相似文献

Special services usage and related assessment procedures were investigated for 50 students with epilepsy. Fifty‐six percent of students with epilepsy received special education services, with mental retardation designation and self‐contained placement common, especially among individuals with epilepsy plus a coexisting neurological diagnosis. Sixteen percent of participants had an “other health impairment” designation, and several of these were deemed eligible in at least one other special education category. The majority of students who had been evaluated were administered IQ, adaptive behavior, speech/language, and sensorimotor components, whereas few were assessed for executive or memory functions. Little information about antiepileptic drugs, their effects, or the actual manifestation of students' seizures appeared in special services school documents. Additional empirical information regarding services for children with chronic health conditions, such as epilepsy, is necessary to improve school psychologists' practice. © 2006 Wiley Periodicals, Inc.

We elaborate a supply chain innovation matrix that can be applied to both commercial and military supply chains. By shifting the analysis from a focal firm to industry structure, we argue that the market structure of the entire supply chain functions as a major moderating variable in determining both the timing and adoption of innovations, both for commercial and military markets. We extend work on supply chain resource dependency by drawing a distinction between market-structure-induced resource dependency and supplier over-reliance on a customer in a competitive market. This has policy implications for the organization of military industrial research and development (IR&D). Joint service research and development (Jointness) will certainly bring about innovation, but it will be incremental, reinforcing established military hierarchies. Policy makers may need to add this probable consequence when comparing Jointness and inter-service rivalry. The cost savings inherent in Jointness may unwittingly sustain a military force unready for fighting the next war. 相似文献

A positive, nonjudgmental, and informed approach to sexual health during pregnancy promotes acceptance of the normal functioning of women's bodies. It also encourages the development of close and supportive relationships that are so essential during pregnancy and birth. Common concerns do not need to become problems. Concerns include issues of libido, positioning, and preterm labor or fetal health, as well as myths and cultural attitudes. Childbirth educators can use tools such as the PLISSIT model to approach the topic of sexuality during pregnancy. In addition, opportunities are available in every childbirth class to acknowledge or ignore sexual issues. Perinatal educators who take responsibility for addressing this often-taboo topic can enhance women's feelings of safety and their confidence in normal birth. 相似文献
