Power Struggles,Regulation and Responsibility     

Sian Barber 《Media History》2018,24(1):99-114

This article explores the relationship between the British Board of Film Classification (BBFC) and government during the implementation of the Video Recordings Act (VRA). It considers the public Parliamentary debates about the VRA, and places them alongside private correspondence between the Home Office and the BBFC, and internal BBFC material from the recently catalogued James Ferman papers held at the BFI. As well as exploring the introduction of the VRA, this article also aims to briefly consider its implications for the BBFC, how they set about interpreting and implementing its stringent recommendations and how this impacted upon the organisational working practices of the Board. While the VRA was without doubt one of the most significant pieces of legislation within the history of film regulation in Britain, the time is ripe for its reappraisal and with it a re-evaluation of the role played by the BBFC in securing statutory regulatory powers.  相似文献   

Accelerometer data requirements for reliable estimation of habitual physical activity and sedentary time of children during the early years - a worked example following a stepped approach

This study presents a worked example of a stepped process to reliably estimate the habitual physical activity and sedentary time of a sample of young children. A total of 299 children (2.9 ± 0.6 years) were recruited. Outcome variables were daily minutes of total physical activity, sedentary time, moderate to vigorous physical activity and proportional values of each variable. In total, 282 (94%) provided 3 h of accelerometer data on ≥1 day and were included in a 6-step process: Step-1: determine minimum wear-time; Step-2: process 7-day-data; Step-3: determine the inclusion of a weekend day; Step-4: examine day-to-day variability; Step-5: calculate single day intraclass correlation (ICC) (2,1); Step-6: calculate number of days required to reach reliability. Following the process the results were, Step-1: 6 h was estimated as minimum wear-time of a standard day. Step-2: 98 (32%) children had ≥6 h wear on 7 days. Step-3: no differences were found between weekdays and weekend days (P ≥ 0.05). Step-4: no differences were found between day-to-day variability (P ≥ 0.05). Step-5: single day ICC’s (2,1) ranged from 0.48 (total physical activity and sedentary time) to 0.53 (proportion of moderate to vigorous physical activity). Step-6: to reach reliability (ICC = 0.7), 3 days were required for all outcomes. In conclusion following a 7 day wear protocol, ≥6 h on any 3 days was found to have acceptable reliability. The stepped-process offers researchers a method to derive sample-specific wear-time criterion.  相似文献   

An Exploration of the Relationship Among Teacher Efficacy,Collective Teacher Efficacy,and Goal Consensus   总被引：2，自引：0，他引：2  

Kurz  Terri Barber  Knight  Stephanie L. 《Learning Environments Research》2004,7(2):111-128

This study explored the relationships among individual teacher efficacy, collective teacher efficacy, and goal consensus/vision. Participants included 113 teachers of a high school located in the southwestern USA. During a teacher inservice meeting, teachers completed three surveys that measured the variables under study. Correlational and regression analyses were performed to examine the relationships among individual teacher efficacy, collective teacher efficacy, and goal consensus/vision. Collective teacher efficacy was found to be correlated with all of the other variables examined, but was most highly correlated with goal consensus/vision. Individual teacher efficacy, while related to collective teacher efficacy, was not found to be related to goal consensus/vision. Findings from this study suggest that, because individual teacher efficacy, collective teacher efficacy and goal consensus/vision are related, changing one could have an impact on the others. This revised version was published online in July 2006 with corrections to the Cover Date.  相似文献

Home and Parenting Resources Available to Siblings Depending on Their Birth Intention Status     

Jennifer S. Barber  Patricia L. East 《Child development》2009,80(3):921-939

This study examines the differential availability of family and parenting resources to children depending on their birth planning status. The National Longitudinal Survey of Youth data were analyzed, 3,134 mothers and their 5,890 children ( M   =  7.1 years, range = 1 month–14.8 years), of whom 63% were intended at conception, 27% were mistimed, and 10% were unwanted. Fixed-effects models show that unwanted and mistimed children had fewer resources than intended siblings. Parents' emotional resources to older children decreased after the birth of a mistimed sibling. Findings suggest that cognitive and emotional resources are differentially available to children within a family depending on intention status and that unintended births lead to decreased parental resources for older children in the household.  相似文献   

Ready for digital learning? A mixed-methods exploration of surveyed technology competencies and authentic performance activity     

Todd J. B. Blayone  Olena Mykhailenko  Roland vanOostveen  Wendy Barber 《Education and Information Technologies》2018,23(3):1377-1402

The Digital Competency Profiler (DCP) is an online application for surveying the technology preferences and abilities of students in higher education. To explore the DCP as a digital-learning-readiness tool, a mixed-methods research design was developed for relating self-reported digital competencies and online-learning activity. To this end, three authentic scenarios, comprised of six tasks mapped to self-report items, were constructed. Having submitted their survey data, each of 15 participants visited the EILAB to complete a randomly-assigned scenario with a tablet. Both the performance activity and post-activity interviews were recorded digitally using a unique activity-station setup, and task artefacts were gathered as performance outcomes. Analysis was conducted in three phases. In Phase 1, both the audio-video performance data and activity artefacts were coded, assessed and scored. Exploratory correlational analyses showed a pattern of positive relationships at the task and scenario levels for two scenario groups, suggesting some predictive value for the DCP in this context. For the third group, a positive correlation was found at the scenario level, but negative correlations were found at the task level. In Phase 2, detailed case-studies were conducted, incorporating self-report data, coded performance timelines, and post-activity interviews. Several situational influencers related to problem-solving strategy, device comfort, task difficulty and motivation, beyond the purview of the DCP, were identified. In Phase 3, the findings were interpreted to position the DCP as a tool for identifying segments of students with members who, without support, will likely struggle to engage fully in technology-rich learning environments.  相似文献

词汇学视角下的《现代汉语词典》编撰特征探讨     

曹志翔  岳士君 《岳阳职工高等专科学校学报》2013,(2):101-104

《现代汉语词典》（第六版）的编撰结合了现当代语言科学发展的成果,在排序、选词、释义、引文上具有鲜明典范的特征。随着当代科技的进步,对照欧美词汇学发展的成果,《现代汉语词典》在选词、释义上出现了片面性、滞后性、高雅化、脱离生活等问题。这些问题的解决有赖于对先进的信息技术、语言学理论的吸收。从具体编撰实际上加以改进。  相似文献
