以受众为中心的电视节目编辑技法研究

美国著名传播学者赫伯特泽特尔在其畅销著作<电视著作手册>中指出"好的编辑必须具备能生动地讲故事和激发观众兴趣的能力".即是要求电视编辑人员对编辑操作从原有的"最有利于叙事"转变为"最有利于受众接受".本文正是在充分考量当前中国电视行业发展背景下,从电视节目编辑人员的视角出发,在受众研究的基础上,从实践的角度探索电视制作各个环节对受众接收信息产生的影响,在镜头的选择、镜头的组接、声音编辑和色彩编辑四个方面做到吸引受众、留住观众.同时,让受众自觉跟随编辑人员的思路接受信息.

Visual and verbal attributes of television and selective attention in preschool children.

Investigated the effect of visual (camera zooms) and verbal (verbal labels) TV attributes on 80 4-yr-olds' visual attention to a prosocial program. Attention was higher when camera zooms were absent than when present, and attention was lowest in the camera-zoom-alone condition. Attention was correlated with learning specific program content but not with prosocial behavior. (6 ref) (PsycINFO Database Record (c) 2010 APA, all rights reserved)

Extrahospital cardiac arrest: the experience of Mestre Emergency Service

BACKGROUND: Out-of-hospital cardiac arrest (AC) is one of the leading causes of death in industrialized countries. AC-related mortality can be reduced by rapid intervention. We report the experience of the emergency medical service (EMS) of Mestre on the management of out-of-hospital AC. METHODS: We analyzed 80 cases of out-of-hospital AC observed consecutively by the EMS of Mestre from February 1996 to September 1997: 72 cases (90.0%) involved cardiac etiology and 8 (10.0%) non-cardiac etiology. The 72 cases involving cardiac etiology were divided in three groups: group A) 12 unwitnessed ACs (16.7%); group B) 12 ACs witnessed by EMS personnel (16.7%); group C) 48 bystander-witnessed ACs (66.6%). RESULTS: In group A, in which 4/12 patients (33.3%) presented ventricular fibrillation (FV) or pulseless ventricular tachycardia (TV) as initial rhythm, return of spontaneous circulation (ROSC) was obtained in one patient with FV and in one patient with asystole. In group B, 7/12 patients (58.3%) presented FV or TV as initial rhythm; in this subgroup, ROSC was obtained in 71.4% of cases (4 cases with FV and one case with TV) and discharge in 42.9%, while in the subgroup with other rhythms the rate of ROSC was 40.0% (two patients with pulseless electrical activity later died). In group C, 35/48 patients (72.9%) presented VF or TV as initial rhythm; in this subgroup, ROSC was achieved in 42.9% of cases (13 cases with FV and 2 cases with TV) and discharge in 14.3%, while in the subgroup of bystander-witnessed AC with other rhythms the rate of ROSC was extremely low (7.7%) (one patient with asystole later discharged). In group C, bystander cardiopulmonary resuscitation (CPR) was performed in 20/48 patients (40.1%). In these patients, FV or TV were more frequently recorded as initial rhythm (80.0 vs 67.9%; p < 0.05). In patients without bystander CPR, the interval between the time of collapse and the time of the first defibrillation was shorter in the patients who were admitted than in patients who died (6.0 +/- 1.4 vs 10.9 +/- 4.4 min; p < 0.05). Considering all patients with FV or TV as initial rhythm and the interval between the collapse and the first defibrillation exactly recorded, the percentage of ROSC decreased when the interval between the collapse and the first defibrillation increased. CONCLUSIONS: Our data confirm that early defibrillation is the key factor in the prognosis of out-of-hospital AC. The data suggest that the immediate delivery of bystander CPR could extend the interval in which defibrillation is effective.     

Relationship of rhythm discrimination to motor rhythm performance.

"Scores on the Seashore tests of time and rhythm discrimination were correlated with performance scores on eight rhythms, each of which were presented at three rates for a total of 24 trials. The above measures were also correlated with the performance of equal short time intervals. Positive and significant correlations between the discrimination and performance tests were obtained, confirming earlier results of R. H. Seashore. Rhythm discrimination scores correlated in all cases higher with rhythm performance than did the time discrimination scores. Rhythm discrimination also correlated as well as or better than did time discrimination with the performance of equal intervals. The need for inclusion of the Seashore time test as one of the musical measures was not confirmed here." (PsycINFO Database Record (c) 2010 APA, all rights reserved)

Courses for credit.

"No course should be offered for credit by TV which has not been approved for inclusion in the college catalog, TV students should meet course standards to which residence students are held, and TV students should ordinarily come to the campus to take their examinations… ." For faculty load accounting, "it is recommended that a one-term television course (three 30-minute programs a week) should equal one-half of a normal full-time teaching load… ." Courses for credit via TV "… can be accomplished with no sacrifice of standards." (PsycINFO Database Record (c) 2010 APA, all rights reserved)
