This study examines the control processes and their dynamics at the board level of two non‐profit organizations with a view to penetrating and exploring directors' control orientations, discourse and decisions in their holistic context. In comparison with the predominantly survey‐ and interview‐based prior research on board‐level control, this study offers a distinctly processual view through its employment of a longitudinal complete member researcher participant observer methodology. Three primary themes of boardroom control focus are identified and analysed. These are control reporting, director's control orientation and the board's budgetary control approach. Directors' strategic orientation is found to be the primary driver of their exercise of control, with reporting systems and routine monitoring emerging as adjuncts to their primary strategic control focus. Strategy‐triggered control activity exhibits itself largely via directors' cost–benefit and risk management analyses communally developed in the course of board meeting exchanges.  相似文献

This study aims to test the public relations efforts of other countries as a predictor of their newsworthiness in the US news media, after controlling for national traits and social significance. Based on a content analysis of US newspaper and television news coverage (New York Times, Washington Post, ABC, NBC, CBS, and CNN) of 97 countries, this study found that the public relations of other countries’ governments is a significant predictor of these countries’ prominence in the US news coverage.  相似文献

Understanding police violence is important in part because police violence, if generally tolerated, could transform a society based on law into one governed by political and personal whim. This research asks whether the conflict perspective can explain which groups are more likely to approve of police use of force, and whether several dimensions of power are at issue or just a few. Previous studies have found that race is the most important factor in determining approval of police use of force. Gender, age, class, and other variables have shown mixed results. Using a national sample (1998 General Social Survey), this paper contributes a more comprehensive examination of this issue to the small body of literature in this area. We look at approval of police use of force in five scenarios. Our findings show that minorities and women are more likely to disapprove of police use of force. Supporting a narrow application of conflict theory, other dimensions of power appear not to affect attitudes toward police hitting citizens. Context of violence matters too. When situations are not actively threatening for officers, by near consensus, violence is unacceptable. Disagreement comes from less clear-cut circumstances.  相似文献

One of the most salient social categories conveyed by human faces and voices is gender. We investigated the developmental emergence of the ability to perceive the coherence of auditory and visual attributes of gender in 6‐ and 9‐month‐old infants. Infants viewed two side‐by‐side video clips of a man and a woman singing a nursery rhyme and heard a synchronous male or female sound track. Results showed that 6‐month‐old infants did not match the audible and visible attributes of gender, and 9‐month‐old infants matched only female faces and voices. These findings indicate that the ability to perceive the multisensory coherence of gender emerges relatively late in infancy and that it reflects the greater experience that most infants have with female faces and voices.  相似文献

This article considers short memory characteristics in a long memory process. We derive new asymptotic results for the sample autocorrelation difference ratios. We used these results to develop a new portmanteau test that determines if short memory parameters are statistically significant. In simulations, the new test can detect short memory components more often than the Ljung-Box test when these short memory components are in fact within a long memory process. Interestingly, our test finds short memory autocorrelations in U.S. inflation rate data, whereas the Ljung-Box test fails to find these autocorrelations. Modeling these short memory autocorrelations of the inflation rate data leads to improved model accuracy and more precise prediction.  相似文献

In binary classifications, a decision tree learned from unbalanced data typically creates an important challenge related to the high misclassification rate of the minority class. Assigning different misclassification costs can address this problem, though usually at the cost of accuracy for the majority class. This effect can be particularly hazardous if the costs cannot be specified precisely. When the costs are unknown or difficult to determine, decision makers may prefer a classifier with more balanced accuracy for both classes rather than a standard or cost‐sensitively learned one. In the context of learning trees, this research therefore proposes a new tree induction approach called subtree grafting (STG). On the basis of a real bank data set and several other data sets, we test the proposed STG method and find that our proposed approach provides a successful compromise between standard and cost‐sensitive trees.  相似文献
