We investigated the effect of window visibility on the computer‐based summarizing of digital documents. Two experiments studied the impact of the simultaneous or alternate display of the windows containing the notepad and source documents. In Experiment 1, the participants were asked to summarize the content of the source documents. In Experiment 2, they were required to copy out sections of the source documents. The results showed that in the alternate condition, the participants performed fewer reading and writing cycles than in the simultaneous condition. Furthermore, in the alternate condition, the writing episodes were both more numerous and more effortful, while quality of the summaries produced using the copying strategy was also affected. These experiments highlight the need for writers to be able to navigate freely and easily between the windows so that they can construct an overall mental representation of their summaries.

The winner's curse phenomenon refers to the fact that the winner in a common value auction, in order to actually win the auction, is likely to have overestimated the item's value and consequently is likely to gain less than expected and may even lose (i.e., it is said to be “cursed”). Past research, using the “Acquiring a company” task has shown that people do not overcome this bias even after they receive extensive feedback. We suggest that the persistence of the winner's curse is due to a combination of two factors: variability in the environment that leads to ambiguous feedback (i.e., choices and outcomes are only partially correlated) and the tendency of decision makers to learn adaptively. We show in an experiment that by reducing the variance in the feedback, performance can be significantly improved. Copyright © 2007 John Wiley & Sons, Ltd. 相似文献

Experiments on three two‐person threshold public good provision games, namely, the simultaneous, sequential, and dictator games, are conducted to explore the motives behind giving. Players who move simultaneously are endowed with equal bargaining power, and players who move first are endowed with more bargaining power than players who move subsequently. Dictators are indubitably endowed with complete bargaining power. Since the differences between the bargaining powers of two players increase from the simultaneous to the sequential to the dictator game, comparisons among games allow us to trace whether the contribution behavior is motivated by fairness or is simply due to the strategic concern. The experimental evidence shows that the strategic concern explains the overall contribution behavior better than the motive of fairness. However, in the final round 26% of the dictators share the threshold evenly with their opponents, suggesting that some subjects do play fairly. Copyright © 2007 John Wiley & Sons, Ltd. 相似文献

This article is an exposition of deep or critical multiculturalism that is grounded in a mutually respectful dialogue. Such multiculturalism names historical oppressions, recognizes the structural causes of injustice and inequality, and is profoundly open to cultural critique, challenge and change. In order to promote such a multicultural practice, the article makes the case for a dialogical politics of deep and mutual respect in which ethno‐religious sensibilities are validated and welcomed in their rich diversity. In doing so, the article draws upon the author's empirical research on the Muslim minority in contemporary Canada. Copyright © 2008 John Wiley & Sons, Ltd. 相似文献

In this study, the authors examined the Substance Abuse Subtle Screening Inventory‐3 Correctional scale's sensitivity and specificity at detecting college students' illegal behaviors. Sensitivity was strong, but specificity was weak. Implications for counseling and suggestions for future research are included. 相似文献

This study examines how substance use is associated with the health and safety of homeless youth using cross-sectional, self-report
data from 285 homeless adolescents. Path models were used to examine concurrent relationships between youth’s substance use
and multiple aspects of their health and safety, including measures of psychological distress, housing risk and instability,
and medical problems. Substance use was examined with both global (i.e., a composite of days of use across various drugs and
alcohol) and specific (i.e., rates of use of specific drugs, injection drug use) measures. After controlling for demographic
and historical variables, number of days of use was significantly related to psychological distress, whereas injection drug
use was significantly related to housing risk. Examination of specific drugs revealed relationships between psychological
distress and the use of alcohol, cocaine, and amphetamines, and a specific relationship between housing risk and the use of
heroin. None of the measures of substance use was significantly related to youth’s medical problems. Implications for interventions
with homeless adolescents are discussed. 相似文献

Research suggests that, in some cases, mechanical restraints may function as positive reinforcers. In this study, we conducted a functional analysis of severe aggression exhibited by an individual with a history of wearing arm splints. The results of this functional analysis demonstrated that his aggression was maintained by access to the arm splints. Copyright © 2008 John Wiley & Sons, Ltd. 相似文献

The current study compared an abbreviated oral interview version of the Pleasant Events Schedule – Alzheimer's Disease (PES‐AD) to a multimedia‐supplemented version. Both measures identified multiple preferred items and their scores were moderately correlated (r = .481). Direct observations were conducted to determine whether either of the two measures predicted subsequent engagement. For all nine individuals with dementia, items endorsed as preferred by both versions of the PES‐AD resulted in high levels of engagement and items endorsed as non‐preferred items on both measures resulted in low to moderate levels of engagement. Individuals with MMSE scores of 10 or higher had more stable and differentiated patterns of engagement than individuals with scores below 10. For individuals with higher MMSE scores, items endorsed only by the multimedia version resulted in high engagement levels (i.e., true positive) while items endorsed only on the verbal presentation resulted in low levels (i.e., false positive).

New Myspace.com users (N = 134, mean age 24.5 years) completed a questionnaire about their intent to blog and several psychosocial variables. Intending bloggers scored higher on psychological distress, self-blame, and venting and scored lower on social integration and satisfaction with number of online and face-to-face friends. Intending bloggers may view this activity as a potential mechanism for coping with distress in situations in which they feel inadequately linked with social supports. 相似文献
