Clinical productivity is an important operational and educational metric for emergency medicine (EM) residents. It is unclear whether working consecutive days and circadian disruption impact resident productivity. The objective of this study was to determine whether there is a correlation between consecutive shifts and productivity.  相似文献

This investigation tested the effectiveness of inoculation as a pre-crisis strategy in combating the effects of politically motivated violent acts. A four-phase experiment was conducted involving 355 national consumer panel participants. The findings indicate that inoculation can be an effective pre-crisis message strategy as it was successful in enhancing public beliefs in the ability of government agencies to prevent, and minimize the effects of, violent acts. This strategy also created a ‘blanket of protection’ that extended beyond the focal politically motivated attack event as it enhanced the confidence in government agencies to manage national crises in general. Inoculation was also effective in lowering the intensity of experienced fear evoked by the threat of violent attacks and it enhanced the ability of individuals to cope with the aftermath of a crisis.  相似文献

Essence magazine is the longest operating magazine catering to a predominately African-American women audience in the US. In 2000, media conglomerate Time Warner purchased 49% of Essence parent company Essence Communications Inc. In 2005, Time Warner purchased the remaining 51% of the black-owned company. As a media conglomerate, Time Warner owns major publishing houses, film, and television production companies, including 130 magazines, New Line Cinema, CNN, and HBO. Essence states it is “the voice and soul of Black women” Collins [Collins, P. H. (2000). Black feminist thought: Knowledge, consciousness, and the politics of empowerment. New York, NY: Routledge] argues that black women must speak in their own voices in order to reject prevailing stereotypes operating on the bodies of black women. The mission statement of Essence aligns itself in what Collins calls “safe spaces” for black women to self-define themselves and articulate their lived realties. A critical theoretical framework allows uneven power relations to be examined and offers emancipatory perspectives. The goal of this study is to examine if Time Warner’s purchase of Essence has caused a shift in the voice and content of this magazine.  相似文献

High‐functioning students with autism spectrum disorder (ASD) have been shown to have significant reading comprehension difficulty. This multiple baseline study examined the effect of the think before reading, think while reading, and think after reading (TWA) strategy on expository text comprehension of four boys with ASD. Following baseline, each student received six sessions of TWA instruction. Data were collected on retell and comprehension question accuracy during the baseline, intervention and maintenance phases. Results supported the effectiveness of TWA as a reading strategy to increase the expository text comprehension of students with ASD. Effects during the intervention phase were immediate and consistent for comprehension questions, with greater variability observed for retell. Data collected at maintenance suggested that the gains were sustained for both comprehension questions and retell.  相似文献

Cell rotation using optoelectronic tweezers   总被引:1,自引:0,他引:1  
A cell rotation method by using optoelectronic tweezers (OET) is reported. The binary image of a typical OET device, whose light and dark sides act as two sets of parallel plates with different ac voltages, was used to create a rotating electric field. Its feasibility for application to electrorotation of cells was demonstrated by rotating Ramos and yeast cells in their pitch axes. The electrorotation by using OET devices is dependent on the medium and cells' electrical properties, the cells' positions, and the OET device's geometrical dimension, as well as the frequency of the electric field.  相似文献

The aim of the National Numeracy Strategy is to raise standards in numeracy. Strong evidence for its success has, however, been lacking: most of the available data come from performance on National Test assessments administered in schools or from Ofsted reports, and is vulnerable to suggestions of bias. An opportunistic analysis of data from a population cohort study extending over three school years compares school‐based scores at school entry and at age 7–8 with clinic‐based scores on similar tests. The results show a small but statistically significant rise between 1998 and 1999 and between 1998 and 2000 in scores on both KS1 arithmetic SATs taken in schools and the arithmetic component of the WISC test taken in an independent research clinic. This is evidence for a real rise in generalised arithmetic ability over this period which may be attributable to the children's experience of the National Numeracy Strategy.  相似文献

This article reports on a year‐long project involving the voluntary participation of 26 Mathematics and English teachers from 14 primary schools in Sarawak, Malaysia. The project had the objective of introducing participants to three important concepts in education: cooperative learning among students, cooperation among teachers and action research by teachers. Components of the ten sessions during which participants met with the project managers were input on cooperative learning and action research, sharing by participants of what they had tried in the classroom, small‐group reflection and planning for future lessons. Data is reported on participants’ responses to the project and on their use of cooperative learning.  相似文献

In two studies, 10‐year‐olds from 2 German special schools as well as typically developing children of the same chronological age (CA controls) or the same mental age (MA controls) were compared on several aspects of working memory functions (i.e., size and input quality of the phonological store, speed and automatic activation of the subvocal rehearsal process). Results reveal that the children from the special schools reached the MA control but not the CA control children's level of non‐word repetition and also showed a statistically significant phonological similarity effect on memory span. These results were interpreted as evidence for a developmental lag in the functioning of the phonological store in these children. With regard to the subvocal rehearsal process, the results were mixed. While the children in the special schools outperformed the MA controls in speech rate, it was found that, in contrast to both control groups, they did not show any word‐length effect on memory span. This finding might be interpreted as evidence for a structural deficit impeding the automatic activation of the subvocal rehearsal process.  相似文献
