Poseidon, the 2006 remake of the Vietnam-era disaster film The Poseidon Adventure, functions rhetorically as a symptomatic response to the historical trauma(s) of 9/11, revising the narrative of its cinematic predecessor and producing a screen memory that marks the changed cultural and historical context that demanded its repetition in the first place. Operating in an allegorical register, Poseidon displaces traumatic memories of 9/11 and thus contributes to the repetition and rewriting of traumatic history in search of mastery over tragic loss.  相似文献

An intervention based on the predictions of Maddux's revised Theory of Planned Behaviour was designed to improve fitness training adherence of a group of elite netball players. The intervention consisted of a persuasive communication and time management workshop, which targeted the social cognitive constructs of the theory. We adopted a multiple baseline across-individuals design over 14 weeks with 17 elite netball players. Baseline training adherence data were collected over the first 7 weeks. The targeted social cognitive constructs were assessed at baseline, post-intervention and follow-up. Large effect sizes for changes in training adherence from baseline to post-intervention were noted for 13 players (76%). Post-intervention analysis revealed significant changes in two of the targeted variables, perceived vulnerability and attitude towards current behaviour, suggesting that the intervention was associated with cognitive changes. Data from an intervention check provided additional evidence to support the efficacy of the intervention. A follow-up assessment over an additional 7 weeks showed that players' training frequency remained improved. The results support the view that the revised Theory of Planned Behaviour can help inform interventions that enhance the training adherence of elite netball players.  相似文献

Abstract

The aim of this study was to determine if inducing metabolic alkalosis would alter neuromuscular control after 50 min of standardized submaximal cycling. Eight trained male cyclists (mean age 32 years, s = 7; [Vdot]O2max 62 ml · kg?1 · min?1, s = 8) ingested capsules containing either CaCO3 (placebo) or NaHCO3 (0.3 g · kg?1 body mass) in eight doses over 2 h on two separate occasions, commencing 3 h before exercise. Participants performed three maximal isometric voluntary contractions (MVC) of the knee extensors while determining the central activation ratio by superimposing electrical stimulation both pre-ingestion and post-exercise, followed by a 50-s sustained maximal contraction in which force, EMG amplitude, and muscle fibre conduction velocity were assessed. Plasma pH, blood base excess, and plasma HCO3 were higher (P < 0.01) during the NaHCO3 trial. After cycling, muscle fibre conduction velocity was higher (P < 0.05) during the 50-s sustained maximal contraction with NaHCO3 than with placebo (5.1 m · s?1, s = 0.4 vs. 4.2 m · s?1, s = 0.4) while the EMG amplitude remained the same. Force decline rate was less (P < 0.05) during alkalosis-sustained maximal contraction and no differences were shown in central activation ratio. These data indicate that induced metabolic alkalosis can increase muscle fibre conduction velocity following prolonged submaximal cycling.  相似文献

The purpose of this study is to find out the frequency of TP53 mutations in acute myeloid leukemia (AML) patients and correlate sensitivity of drug response with TP53 mutations. In AML more than 90 % of cases comprise of wild type TP53. 94.2 % of TP53 mutations are found within exon 5–8 of which 73 % are point mutations. TP53 mutations were analysed with high resolution melting curve analysis. We analysed 106 AML samples of which we found nine mutations which represents 8.5 % mutation rate and found one rare SNP. The effect of TP53 mutations were studied on the chemosensitivity of two new drugs AZD115 and RHPS4, an Aurora Kinase B inhibitor and Telomerase inhibitor respectively. Four mutations were found out of 17 for RHPS4 stating significant (p = 0.002) increase in sensitivity and no mutation found in AZD1152 database, but need more study to get definite conclusion.  相似文献

This paper reports on the first stage of an investigation into monitoring and evaluating the impact of information management (IM) within a local government context. The overall study will utilise a combination of principles from various results-based, outcomes-based and social change approaches (Logical Framework Analysis, Most Significant Change, and Outcomes Mapping) in an attempt to move Leicestershire County Council away from a culture focused on traditional performance measurement, i.e. percentage change in use of services provided to the public, to something of real value. Interviews with 20 senior managers highlighted the important IM issues for Leicestershire County Council as a local government. These initial findings showed that maintaining high quality, trusted, and governed information and knowledge resources were of great value to the organisation. Analysis showed that 85% of senior managers interviewed considered IM to be “critical” in the achievement of organisational outcomes. Further analysis enabled the development of an initial framework indicating key areas where IM can have impact. These key areas will become the focus of further research, where applying a combination of approaches aforementioned will define the boundary partners, their specific outcomes and progress markers with possible impacts proposed. This detail will help to develop a framework for measuring the impact of IM.  相似文献

Data from 188 white and 97 black children supported the following conclusions: (a) A general cognitive factor prevailed throughout a group of tests including the Peabody Picture Vocabulary Test administered at age 3 years, the Preschool Inventory, the Boehm Test of Basic Concepts (modified), and the Graham-Ernhart Copy-Forms Test administered at age 4 years; (b) Correlations of three scales of the Preschool Attainment Records and the Verbal Language Development Scale with the other measures were less consistent; (c) the correlations of the Quick Test with other tests were satisfactory for white children but inconsistent for a subsample (N = 18) of black children; (d) the standard deviations of the Quick Test IQs were excessively large; and (e) differential scoring of Preschool Inventory subtests was not supported.  相似文献

This paper explores the implications of thedevelopment and extension of national andinternational intellectual property regimes (IPRs) forthe liberal university. It argues that dynamics setinto motion by IPRs are eroding the university'sability to reproduce itself in two ways. On the onehand, IPRs are reducing the university's ability todraw on and to replenish the intellectual commonswhich is one fundamental precondition of its survival.IPRs are also preventing academics from fulfillingtheir public service mission which may undermine thepopular support for the university that is alsocrucial to its survival. These two mutuallyreinforcing developments are making it increasinglydifficult for the liberal university to continue on asit has. Indeed, they are producing a qualitativetransformation of the institution that will be verycostly to society, in both economic and social terms.The paper argues that although current developmentspose very serious threats to the liberal university'sfuture, there is still time to intervene in order topreempt or to alter them. The paper concludes with adiscussion of strategies that may enable the liberaluniversity to survive, if not flourish, in the currentcontext. In particular, a strategy of pursuing broadIP exemptions for universities isadvocated.  相似文献
