The public interest is commonly presumed to be fundamental to the practice of journalism. Journalists and the media organizations for which they work routinely assume that they are able to identify what is in the public interest, and act accordingly. This article explores notions of the public interest in the context of a particular case study, that of Sharleen Spiteri, an HIV-positive sex worker who appeared on the Australian national current affairs television programme 60 Minutes in 1989 and admitted that she sometimes had unprotected sex with clients. As a consequence of the ensuing wave of moral panic, she was forcibly detained in a locked AIDS ward and a mental asylum. After she was released she was kept under 24-hour surveillance for the remaining 15 years of her life. In 2010, the authors of this article produced a radio documentary for the Australian Broadcasting Corporation about Sharleen Spiteri's case. The authors argue that her story raises some important and difficult questions for the ethical practice of journalism. They analyse the role of journalists and politicians involved in Sharleen's case, and show that their belief that they were acting in the public interest played into well-established historical narratives linking sex workers with disease and dissolution, with disastrous consequences for Sharleen herself. The authors argue that a more reflexive and responsible conception of the public interest for journalists requires them to pay more careful attention to the voices and perspectives of people who are excluded from participation in the public sphere. 相似文献

Ten rats pressed levers for food reinforcers delivered by multiple schedules. Behavioral contrast was measured using a within-session procedure that presented the baseline and contrast schedules within single sessions. The absolute sizes of both positive and negative contrast increased and then decreased as components lengthened. Negative induction occurred when components were very short. These results question theories that predict that the size of contrast will vary inversely with component duration. They support theories that attribute positive and negative contrast to similar theoretical mechanisms. A comparison of the present results with those of past studies indicates that keypecking by pigeons and leverpressing by rats change as different functions of component duration. Treadlepressing by pigeons and leverpressing by rats change as similar functions. These findings challenge general process theories that argue that all responses obey the same behavioral laws. 相似文献

An important goal of education in developing countries is to implement and improve early childhood education. A pre–post intervention–control design was used to compare a piloted-revised versus a regular preschool program offered by an organization in rural Bangladesh. After 7 months in operation, the quality of the piloted-revised program was higher than the regular program, though the regular program had also improved. Children attending pilot preschools made greater gains than children attending regular preschools on most outcome measures. Action research was conducted alongside the quantitative evaluation to study the process of the implementation and to identify areas for further improvement. 相似文献

AbstractTeachers require specialised assessment knowledge and skills in order to effectively assess student learning. These knowledge and skills develop over time through ongoing teacher learning and experiences. The first part of this paper presents a Summative Assessment Literacy Rubric (SALRubric) constructed to track the development of secondary science teachers’ summative assessment literacy. The analytic rubric consists of 10 dimensions spread across three categories drawn from the literature and context-specific empirical evidence: knowledge of assessment, understanding the context for assessment, and recognising the impact of assessment. The second part of this paper applies the SALRubric in a case study to explore the development of summative assessment literacy of New Zealand secondary science pre-service and novice teachers. An increasing sophistication in these teachers’ summative assessment literacy was evident over 20 months albeit in a nuanced manner for individual teachers. The rubric was a very useful tool for evaluating and documenting shifts in teachers’ summative assessment literacy over time. Implications of the use of SALRubric are discussed in terms of summative assessment literacy practice and development. 相似文献

Students taught by teachers of science with a higher I/D ratio, according to Flanders scale, will achieve more and retain more information than will students of teachers with a lower I/D ratio. This study tested students in high school chemistry and junior high school general science at the end of a year of study in their respective classes. They were then retested four months later. The teachers were scaled according to their I/D ratio. It was found that the I/D ratio of a teacher could be a guide toward determining the success of students so taught in a particular class. 相似文献

A three-year research project at the University of Southampton (2007–2010) investigated whether monitoring techniques commonly used by engineers to assess the strength and durability of materials could be usefully applied to inform the condition assessment of historic tapestries. To date it has not been possible to obtain an objective picture of the overall condition of a tapestry; the study investigated whether it is possible to identify precursors of structural damage. The two techniques, digital image correlation (DIC) and optical fibre sensors, were used to monitor a representative wool fabric, specially woven tapestry samples, a newly woven tapestry, and historic tapestries, both in the laboratory and in situ in a historic house. This study first sets out to answer the question: can DIC be used to monitor and visualize strain in historic tapestries? It is shown that DIC can be used successfully. Secondly, it discusses the map function, a novel development which allowed the monitoring equipment to be moved, so that it could be used in situ in a historic house. Thirdly, it provides further details of the experimental work using optical fibre sensors to confirm the accuracy of the DIC technique. 相似文献

There has been a need to identify a quick screening and reevaluation instrument to determine eligibility status for specialized programs. The Slosson Intelligence Test (SIT) is one instrument that has been suggested for this purpose. In a ten-year review of validity studies with the SIT, Stewart and Jones (1976) found substantial correlations between the SIT and WISC. They recommended that future validity studies with the SIT focus on specific subgroups with restricted IQ ranges. The present study compared the SIT with the WISC-R for a group of intellectually gifted students. The results indicated reduced correlations between the measures. The calculated regression equation was dissimilar to the one reported by Stewart and Jones for nonrestricted IQ populations, although predictive ability was greater. The need for comparing the SIT with other measures for specific subgroups was supported. 相似文献
