战国时期楚方言第一人称代词句法功能及谦敬功能计量考察     

尹喜艳 《温州职业技术学院学报》2012,12(3):78-80

通过考察发现,在《楚辞》屈原和宋玉的作品中,战国时期楚方言第一人称代词系统由“余（予）”、“吾”、“朕”、“我”组成,其中,“余（予）”句法功能最完备,“吾”宾语功能存在不足,“朕”不作定语,“我”不作宾语,且这些第一人称代词都不具有谦敬功能。  相似文献   

Reexamining the Link Between Cultivation Factors and Viewer Involvement: Investigating Viewing Amount as a Catalyst for the Transportation Process     

Sean M. Horan  Matthew M. Martin  Nicole Smith  Meghan Schoo  Mary Eidsness  Angela Johnson 《Communication Studies》2013,64(1):66-81

In an effort to expand on prior cultivation research involving narrative processing (Bilandzic &; Busselle, 2008 Bilandzic , H. , &; Busselle , R. W. ( 2008 ). Transportation and transportability in the cultivation of genre-consistent attitudes and estimates . Journal of Communication , 58 ( 3 ), 508 – 529 . doi: 10.1111/j.1460–2466.2008.00397.x [Crossref] , [Google Scholar]), this study examined the interrelationships between viewing amount and the transportation process. Results showed that transportation mediated the relationship between genre-specific television viewing and perceived realism, while overall television viewing directly predicted reduced counterarguing. In addition, structural equation modeling was employed to test a combined cultivation-transportation model leading to changes in viewer excessive drinking perceptions. Findings indicated that genre-specific television viewing indirectly influenced beliefs through increased transportation. Conversely, a significant, direct path was found between overall viewing and excessive drinking beliefs, supporting the original cultivation perspective.  相似文献   

FOREIGN OFFICE CONTROL OF REUTERS DURING THE FIRST WORLD WAR     

Jonathan Silberstein-Loeb 《Media History》2013,19(3):281-293

I disagree with Professor Putnis' claim that the Foreign Office instigated a leveraged buyout of Reuters in 1915. Putnis' thesis is questionable for several reasons. (1) It is at odds with a general unwillingness on the part of government to interfere in the affairs of private business. (2) The fear of a hostile foreign takeover was neutralized and there was no compelling reason to buy out Reuters. (3) It is improbable that the Foreign Office would have devised a plan to take over Reuters before other aspects of wartime mobilization, such as armaments, were decided. Instead, I argue that Reuters initiated an agreement with the Foreign Office to fulfil its strategic aims. Once this is appreciated, the long-term and significant effects of the buyout become apparent.  相似文献

Language,literacy, attentional behaviors,and instructional quality predictors of written composition for first graders     

Young-Suk Kim  Stephanie Al Otaiba  Jessica Folsom Sidler  Luana Gruelich 《Early childhood research quarterly》2013

We had two primary purposes in the present study: (1) to examine unique child-level predictors of written composition which included language skills, literacy skills (e.g., reading and spelling), and attentiveness and (2) to examine whether instructional quality (quality in responsiveness and individualization, and quality in spelling and writing instruction) is uniquely related to written composition for first-grade children (N = 527). Children's written composition was evaluated on substantive quality (ideas, organization, word choice, and sentence flow) and writing conventions (spelling, mechanics, and handwriting). Results revealed that for the substantive quality of writing, children's grammatical knowledge, reading comprehension, letter writing automaticity, and attentiveness were uniquely related. Teachers’ responsiveness was also uniquely related to the substantive quality of written composition after accounting for child predictors and other instructional quality variables. For the writing conventions outcome, children's spelling and attentiveness were uniquely related, but instructional quality was not. These results suggest the importance of paying attention to multiple component skills such as language, literacy, and behavioral factors as well as teachers’ responsiveness for writing development.  相似文献   

Social Justice Becomes a Living Experience for Students,Faculty, and Community     

Robert Blundo 《Journal of Teaching in Social Work》2013,33(1):90-100

This social justice course was the result of a service‐learning project with African American and First Nations peoples of a Southern community telling their story of desegregation through the creation of a video documentary project. Combining the pedagogy of service‐learning with documentary video making, a social justice project was created that impacted students, faculty, and community.  相似文献
