展品是科技馆从事科学传播的重要载体,展品是否完好运行关系到观众的参观体验,也关系到依托展品而开展的科学辅导、展览教育活动的实施。展品互动性强、故障率高,解决展品故障问题的及时维修、解决展品使用寿命和减少故障率问题的维护保养是实体科技馆面临的重要课题。本文依据“使用与满足”理论,提出以观众为中心确立科技馆展品的评价标准和“不给观众短斤少两”的展品维修理念;科技辅导员是展品维修业务的直接用户。以此为基础组织展品维修维护团队,构建以满足用户需求为导向的、涉及展品维修维护业务流程、评价标准、评价体系、评价结果应用以及维修物资保障等内容的展品维修维护管理体系。 相似文献

计算机是由硬件和软件合二为一的产品,两者缺一则不可以使用;也可以说,两者之一发生故障也会影响正常使用。所以,对计算机的维护和维修,不但要懂得硬件的相关知识,而且还要懂得软件的相关知识。因此,只有掌握硬件和软件的基本知识和技术,才能搞好计算机的维护和维修工作。 相似文献

This study examines the extent to which an athlete’s race impacts the image repair process within media-filtered athlete transgressions by utilizing a 5 (race) × 3 (response strategy) factorial experiment and employing Benoit’s (1995) image repair typology. Reponses from a national sample of 215 participants revealed that, independent of race, the mortification strategy was more effective for repairing an athlete’s image compared to reducing offensiveness and evading responsibility strategies, supporting current image repair studies. This study also revealed that the athlete in the White condition was uniformly viewed as being less successful than four other racial conditions (Asian, Black, Hispanic, and Middle Eastern) in achieving image repair, a new result within this stream of image repair scholarship. Conclusions related to social identity theory and expectancy violation are rendered. 相似文献

The candidates for the Democratic presidential nomination in 2004 were united in attacking President George W. Bush. Their continued criticism, combined with news stories about such topics as the failure to find weapons of mass destruction in Iraq and job losses in the United States, steadily eroded the president's image. On February 8, 2004, President Bush appeared on Meet the Press to repair his reputation, exemplifying the problem of how an incumbent president can reply to such attacks while in the midst of a campaign for re-election. This essay applies the theory of image repair to this discourse to critically analyze and evaluate Bush's attempt to repair his image. Bush responded to two key accusations: justification for the war in Iraq and concerns about the economy (including jobs and the deficit). He tried to frame himself as a “war president” (transcendence) who should be evaluated on those grounds but failed to make this the most important problem for most voters. He employed denial, but the support for denials was often weak. He also relied heavily on defeasibility. However, Bush's use of the strategy of defeasibility raises doubts about whether he will be able to solve problems in a second term. Thus, President Bush's image repair effort was largely ineffectual. 相似文献

The study advances a typology of antapologia (discursive reply to apologia) by examining Soviet responses to U.S. image repair during the 1960 U-2 incident. Following U.S. image repair, the Soviets used strategies designed to strengthen its persuasive attack on the United States as well as to weaken U.S. apologia. 相似文献

This study examines some of the reconciliation and repair/maintenance strategies in the relational communication literature. These strategies were compared with Bell and Daly's (1984) affinity‐seeking strategies. It was concluded that Bell and Daly's strategies could identify many of the same relational strategies with less contextual confusion. It is argued that affiliation strategies represent a true multiphasic relational communication typology that applies to the range of repair/reconciliation contexts. The study then looks at the degree to which assertiveness, and responsiveness predicts the use/non‐use of affinity seeking strategies in the context of relational repair. The study indicates that self perceived assertiveness and responsive play a role in strategy selection as well. Finally, how others are perceived in terms of assertiveness and responsiveness was found to predict the types of strategies used and not used in relational repair contexts. 相似文献

In October 2016, Donald Trump was in the midst of a hotly contested and sharply divisive presidential campaign. Days before the second presidential debate, The Washington Post posted a video of Trump “having extremely lewd conversation about women in 2005.” This video and the firestorm of criticism it provoked threatened to derail his presidential run. Mr. Trump and his wife Melania Trump offered several messages to repair his damaged image. This article analyzes and evaluates these image repair messages concerning Donald Trump’s “Access Hollywood” video. In such a divisive context, the defense had no hope of repairing Trump’s image with the general public (Trump lost the popular vote by 2.9 million). Even though he lost the popular vote, the business magnate won the Electoral College. We cannot say that the “Access Hollywood” video was solely responsible for Trump’s poor popular vote showing, but it is clear that this defense did not completely dispel the cloud surrounding him. 相似文献

NPR analyst Juan Williams appeared on The O'Reilly Factor and said that he gets “worried” and “nervous” when he sees people in Muslim dress on airplanes. Two days later NPR fired Williams and the day after that Williams issued a serious accusation against NPR: “I was fired for telling the truth.” Criticism of NPR mounted—arising particularly from conservative commentators—and CEO Vivian Schiller disseminated a statement defending her organization. This essay applies the theory of image repair discourse to NPR's CEO Vivian Schiller's apology for firing Williams. Two accusations were in play and they prompted two distinct defenses: Her reaction to accusations that NPR had not followed appropriate procedures for termination Williams employed the strategies of mortification and corrective action and her defense of the firing itself used transcendence, bolstering, and attack accuser. This essay evaluates this defense as a poor example of image repair. 相似文献
