Studies about mass media framing have found divergent levels of influence on public opinion; moreover, the evidence suggests that issue attributes can contribute to this difference. In the case of climate change, studies have focused exclusively on developed countries, suggesting that media influence perceptions about the issue. This study presents one of the first studies of media coverage in a developing country. It examines newspapers' reporting in Peru during the Fifth Latin America, Caribbean and European Union Summit in May 2008. The study focuses on the frames and the sources to provide an initial exploratory assessment of the coverage. The results show that the media relied mostly on government sources, giving limited access to dissenting voices such as environmentalists. Additionally, a prominence of "solutions" and "effects" frames was found, while "policy" and "science" frames were limited. The results could serve as a reference point for more comprehensive studies.  相似文献   

Multispectral data cube acquisition of aligned images for document analysis by means of a filter-wheel camera provided with focus control     

Gianfranco Bianco  Fabio Bruno  Maurizio Muzzupappa 《Journal of Cultural Heritage》2013,14(3):190-200

Multispectral imaging techniques are widely used to analyse and restore digital images of ancient documents degraded over time. In particular, acquisitions in infrared and ultraviolet bands can reveal information invisible by naked eye, which is not captured by conventional RGB imaging. Multispectral acquisitions are usually performed with filter-wheel cameras that mount a series of interference filters in front of the sensor to select the spectral band in which the document has to be acquired. Due to the use of different filters, the focus of the lens changes and it is necessary to adjust it manually for each filter, because such imaging systems are devoid of automatic focusing. Thus the acquired images may not be perfectly in-focus and have misalignments. In this work we present an automatic solution to acquire a multispectral data cube of aligned images that can be used in document analysis to extract and/or separate information through enhancement techniques. A custom-made motorized autofocus system controlled by software has been installed on a filter-wheel camera, which allows us to acquire in-focus images automatically at each filter changing, and a registration method based on Fourier-Mellin transform aligns these images. A preliminary calibration is performed to set the focusing of each filter with the working distance. As a result, the camera can capture images independently from the contrast of the scene, also in presence of documents with homogeneous texture. The proposed solution reduces considerably the acquisition time and offers a tool to acquire automatically the data cube to be used in further image analysis techniques. The results of experimentations are hereby presented and discussed.  相似文献   

农村学校撤并对学生上学距离的影响——基于GIS和Ordinal Logit模型的分析   总被引：1，自引：0，他引：1  

赵丹  吴宏超  Bruno Parolin 《教育学报》2012,(3):62-73

农村义务教育学校布局调整是以撤并小规模学校为主要手段,旨在促进教育资源均衡配置的一项重大教育政策。通过广东省某山区县2003—2009年的学校布局规划数据,从物理距离、时间距离和文化距离的分类视角,运用GIS技术和Ordinal Logit模型分析农村学校撤并对学生上学距离产生的直接影响。研究结果表明:撤并农村学校导致学生上学的物理距离和时间距离增加,偏远学生上学难问题凸显;对学生的文化距离同样产生显著的负面影响。在未来学校布局调整的进程中,县域教育决策者应将关注点从一味追求规模效益转移到教育公平和教育质量上来。要保证农村学生就近入学,设定上学距离的限制;促进学校间教育资源的均衡配置,保证所有学生享受同等质量的教育资源;采用科学的规划程序完善布局调整政策的实施。  相似文献   

Ivan Illich's Late Critique of Deschooling Society: “I Was Largely Barking Up the Wrong Tree”     

Rosa Bruno‐Jofré  Jon Igelmo Zaldívar 《Educational theory》2012,62(5):573-592

In this article, Rosa Bruno‐Jofré and Jon Igelmo Zaldívar examine Ivan Illich's own critique of Deschooling Society, and his subsequent revised critique of educational institutions and understanding of education, within the context of both his personal intellectual journey and the general epistemological shift that started to take shape in the early 1980s. Bruno‐Jofré and Zaldívar consider how, over time, Illich refocused his quest on examining the roots (origin) of modern certitudes (such as those related to education) and explored how human beings are integrated into the systems generated by those “certainties.” Illich engaged himself in historical analysis rather than providing responses to specific contemporary problems, while maintaining an interest in the relation between the present and the past. Under the metaphors of the word, the page, and the screen, he identified three great mutations in Western social imaginaries and the reconstruction of the individual self. Bruno‐Jofré and Zaldívar argue that while his written work, including Deschooling Society, generally had an apophatic character, his critique of education, particularly in the late 1980s and 1990s, is intertwined with his analysis of the parable of the Good Samaritan and his belief that modernity is an outcome of corrupted Christianity.  相似文献

Validity and reliability of a 6-a-side small-sided game as an indicator of match-related physical performance in elite youth Brazilian soccer players     

Rodrigo Aquino  Bruno Melli-Neto  João Victor S. Ferrari  Bruno L. S. Bedo  Luiz H. Palucci Vieira  Paulo Roberto P. Santiago 《Journal of sports sciences》2013,31(23):2639-2644

ABSTRACT

The aims of this study were: (i) to compare the external and internal load during a 6-a-side small-sided game (6v6-SSG) according to age-group; (ii) to relate these parameters between the 6v6-SSG and official matches; and (iii) to test the reliability of the 6v6-SSG. A total of 51 Brazilian youth soccer players participated in this study (U11 [n = 16]; U13 [n = 10]; U15 [n = 9]; U17 [n = 8]; U20 [n = 8]). Three experiments were conducted. Experiment A: fifty-one U11 to U20 players were submitted to 6v6-SSGs (n = 10 games; two for each age-group). Experiment B: thirty-two players were randomized to also play official matches (n = 6 matches). Experiment C: thirty-five youth players played the 6v6-SSG twice for test and retest reliability analysis. External load was obtained using Global Positioning Systems and the internal load parameter was calculated through mean heart rate. Statistical approaches showed progressive increases in all parameters according to categories (U11< U13< U15< U17< U20; p < 0.05; ES = 0.42?23.68). Even controlling for chronological age, all parameters showed likely to almost certain correlations between 6v6-SSG and official matches (r = 0.25?0.92). Collectively, the proposed protocol indicates good reliability (CV% = 2.0?12.6; TE% = 2.3?2.7%; ICC = 0.78?0.90). This research suggests that the 6v6-SSG is an alternative tool to indicate match-related physical performance in youth soccer players.  相似文献   

Effects of replica running shoes upon external forces and muscle activity during running     

Ana Paula Da Silva Azevedo  Kátia Brandina  Roberto Bianco  Vitor Henrique De Oliveira  Juliana Roque De Souza  Bruno Mezencio 《Journal of sports sciences》2013,31(9):929-935

Abstract

Twelve participants ran (9 km · h^?1) to test two types of running shoes: replica and original shoes. Ground reaction force, plantar pressure and electromyographic activity were recorded. The shoes were tested randomly and on different days. Comparisons between the two experimental conditions were made by analysis of variance (ANOVA) test (P ≤ 0.05). The time to first peak, loading rate of the first peak and impulse of the first 75 ms of stance were significantly different between the shoes (P ≤ 0.05), revealing an increase of impact forces for the replica shoes. The peak plantar pressure values were significantly higher (P ≤ 0.05) when wearing replica shoes. During running, the contact area was significantly smaller (P ≤ 0.05) for the replica shoe. The electromyographic activity of the analysed muscles did not show changes between the two shoes in running. These findings suggest that the use of replica running shoes can increase the external load applied to the human body, but may not change the muscle activity pattern during locomotion. This new mechanical situation may increase the risk of injuries in these movements.  相似文献

Archival science facing the information society     

Bruno Delmas 《Archival Science》1987,1(1):25-37

It is only a few decades ago that archivists befan to redefine theirdiscipline in terms of a science. This redefinition of archives and records management was the consequence of a growing need for an adequate expression referring to a comprehensive new body of knowledge on records and archives. Consensus on how to adequately define archival sciencehas not been achieved yet, however. As information society evolves,records and archives are changing in nature and status. It is anemerging discipline that has to be defined, which is still bearsthe impress of the mindset and practices of the industrial society.Bruno Delmas shows the archivist some clues to find a way out of thisambiguity and keep communicating human heritage to unknown generations.  相似文献
