Overshadowing of environmental cues by an odor in toxicosis-based conditioning in rats     

Harald Taukulis  Shane St. George 《Learning & behavior》1982,10(3):288-292

It was demonstrated that an odor presented to rats in a distinctive environment can interfere with toxicosis-based conditioning to the environmental cues. Rats poisoned when they drank unflavored water in a black compartment odorized with oil of eucalyptus exhibited no suppression of water intake when they were subsequently tested in the same compartment minus the odor. In contrast, rats poisoned in the same compartment minus the odor later exhibited reduced water consumption in that environment. Oil of eucalyptus proved to be as effective an overshadowing stimulus as a taste cue (a 1.5% NaCl solution).  相似文献   

Queer pedagogy,educational practice and lesbian and gay youth     

Kathleen Quinlivan  Shane Town 《International journal of qualitative studies in education》2013,26(5):509-524

Our article explores the potential that queer paradigms and pedagogies hold for affirming sexual diversity in secondary schools. In understanding the operation of schools as heteronormalising institutions, it is possible to move beyond viewing queer youth as a disenfranchised minority group requiring reparation within an equity framework (a process that we suggest operates simultaneously to legitimate heterosexuality and to reinforce the abnormality of same-sex desire). Using research that we have undertaken with lesbian and gay youth in New Zealand secondary schools, and drawing on queer, post modern and feminist theoretical threads, we explore three (hetero) normalising processes experienced by the queer participants in their schools; the maintenance of silences, the pathologisation of (homo)sexualities, and the policing of gender boundaries. We close by exploring how several queer pedagogical features - creating venues, abnormalising the normal, dissolving the homo/hetero binary and forming alliances - could be used in order to affirm the sexual diversity of secondary school students.  相似文献   

Perceptual Decision Making for Baseball Pitch Recognition: Using P300 Latency and Amplitude to Index Attentional Processing

Abstract

This study was designed to examine the perceptual and attentional processes associated with the effects of administering a cost-benefit precuing paradigm to intermediate and advance-level baseball batters. Psychophysiological and performance data obtained from 10 advanced and 10 intermediate-level players were compared. A total of 400 pitches (200 fastballs, 200 curveballs) was randomly presented via a large projection screen, and participants pressed one of two buttons to indicate the type of pitch thrown. Verbal precues were given for 300 of the pitches. Of those, 75% were valid, and 25% were invalid. Electroencephalographic data collected from the P_z location was used to assess the latency and amplitude of P300. Analysis of variance (Skill Level x Precue x Pitch) for P300 and reaction time (RT) indicated that intermediate batters produced shorter P300 latencies, larger P300 amplitudes, longer RTs, and less correct responses than the advanced batters; the effects were more pronounced for the curveballs. These results suggest that intermediate batters are less efficient in their perceptual decision-making processes due to greater limitations in attentional capacity when compared with advanced batters.  相似文献

From vision to reality—Managing changein the provision of library and information services to nurses,midwives, health visitors and PAMs:a case study of the North Thames experience with the Inner London Consortium     

Shane Godbolt  Jane Williamson  Andrea Wilson 《Health information and libraries journal》1997,14(2):73-95

One ofthe North Thames’ pioneering consortia, the Inner London Consortium (ILC) is a complexbody which includes NHS Trusts with teaching hospital university connections, community-basedTrusts and general hospital acute Trusts. Within the consortium there are 12000 trained nurses,midwives, health visitors and other professional staff working in the professions allied to medicine(PAMs), all of whom require access to and provision of appropriate library information services. In 1994, taking into account experiences elsewhere in the Region and nationally, itbecame clear that library issues were complex and would become acute with the move of nursinglibraries from ILC Trust sites over a very short timescale. A report on the issues commissioned bythe Consortium recommended that a library project, which built on existing NHS Trust PGMDEfunded library resources and moved these to a multidisciplinary base to serve the consortiummembership, be implemented. The objective of providing access to library informationservices for nurses and PAMs was achieved. Successes that emerged from the implementationincluded: The registration in Trust libraries of almost 12000 new members within theinitial 6-month monitoring period. The development of service level agreements andstandards for the delivery of services to these new user groups. This paper describes theprocesses behind these significant and complex changes.  相似文献

Digital dark matter and the economic contribution of Apache     

Shane Greenstein  Frank Nagle 《Research Policy》2014

Researchers have long hypothesized that research outputs from government, university, and private company R&D contribute to economic growth, but these contributions may be difficult to measure when they take a non-pecuniary form. The growth of networking devices and the Internet in the 1990s and 2000s magnified these challenges, as illustrated by the deployment of the descendent of the NCSA HTTPd server, otherwise known as Apache. This study asks whether this experience could produce measurement issues in standard productivity analysis, specifically, omission and attribution issues, and, if so, whether the magnitude is large enough to matter. The study develops and analyzes a novel data set consisting of a 1% sample of all outward-facing web servers used in the United States. We find that use of Apache potentially accounts for a mismeasurement of somewhere between $2 billion and $12 billion, which equates to between 1.3% and 8.7% of the stock of prepackaged software in private fixed investment in the United States and a very high rate of return to the original federal investment in the Internet. We argue that these findings point to a large potential undercounting of the rate of return from IT spillovers from the invention of the Internet. The findings also suggest a large potential undercounting of “digital dark matter” in general.  相似文献   

What Do We Mean by Cyberlearning: Characterizing a Socially Constructed Definition with Experts and Practitioners   总被引：1，自引：1，他引：0  

Devlin B. Montfort  Shane Brown 《Journal of Science Education and Technology》2013,22(1):90-102

The term “cyberlearning” reflects a growing national interest in managing the interactions of technology and education, especially with respect to the use of networking and information technologies. However, there is little agreement about what the term means. Such disagreements reflect underlying differences in beliefs about the purposes of education. These disagreements are problematic for anyone interested in evaluating cyberlearning practices. This study used surveys and interviews to investigate how practitioners and experts in the field of cyberlearning define it, how they implement it and what they believe its purpose to be. Little agreement was found among participants in terms of their definitions of cyberlearning, which was supported by the wide variety of practices labeled “cyberlearning.” Although most participants emphasized the purpose of cyberlearning as a form of content delivery, an often-passionate minority argued for the potential of cyberlearning to encourage a shift away from content-delivery paradigms. The participants’ spoke from a variety of perspectives about cyberlearning including as educators, designers, activists, and policymakers, which led them to construct diverse narratives about the purposes and problems facing education and education policy. While the differences in embodied in these narratives remain an important consideration, some emerging points of convergence are identified.  相似文献
