It will focus on Hare＇s selection of detail in his they manifest themselves in David screenplay The Reader; a dramatic adaptation of Bernhard Schlink＇s novel of 1995. This will involve comparing the novel to the dramatic text for the purpose of showing the movement from narrative to dramatic rendering. The paper aspires to reach the conclusion that Hare＇s screenplay, The Reader creates a world of signification where the interplay of guilt, love, and forgiveness shape the textual and stage space. Read in light of Shoshana Felman＇s The Juridical Unconscious （2002）, the play investigates the traumatic history of Nazi Germany with scope for analysis of guilt and forgiveness and the possibility of atonement through love and literature. The focus of the paper will be on the ideological and formal structure of the play and its impact on meanings and interpretations.展开更多

We find that short sellers rely on firms' fundamental information, especially relative financial indicators, to locate their "prey." Specifically, they compare a target firm's financial indicators(e.g., growth and receivables) with both the industry average and the firm's history. We find no evidence that short sellers accuse CRMs simply because of their reverse merger label. Additionally, we test the accuracy of short sellers' accusations in the long run and find that accused firms are more likely to delist and less likely to recover from price plunges. Our results also indicate that CRMs' high exposure to short sellers' accusations stem from adverse selection problems: firms with high litigation risk are more likely to choose reverse mergers to access the US capital market. Overall, our results support the view that short sellers are sophisticated investors and shed some light on their decision processes.展开更多

An old and re-emerging issue is the morality and reparative behavior in Western versus Eastern cultures, as well as its antecedents and consequences. We examined the effects of acculturation on the perception of psychological proximity, the intensity of moral emotions of shame and guilt, and the degree of compensation to victims of one＇s wrongdoing. Our sample was comprised of a collectivistic group from a shame culture, China, and an acculturated group of Chinese living in a much less collectivistic society of a guilt culture, Canada. Our results indicated that participants＇ perception of psychological proximity to other people and the level of compensation offered to the victims of transgression were significantly different among the two samples. Furthermore, shame and guilt mediated the relationship between perceived psychological proximity and the decision to compensate differently.展开更多
