This paper explores the application of an affective content analysis to a selection of nanotechnology news articles gathered
from selected newspapers. Thematic content analyses dominate current efforts to mine large text collections of popular science
media; the addition of an affective analysis element can yield useful information to supplement future content analysis efforts.
Using Whissell’s Dictionary of Affect in Language, the analysis rates news articles gathered over a twenty-two year period for their pleasantness, activeness, and imagery,
determining the mean affective tone in each category for the entire collection, four ‘content themes’ (business, national
security, health, and environment), and the change in affective tone over the twenty-two year period these articles represent.
Whereas the entire collection analyzed as a whole rates very similarly to the average found for everyday English language
use and the ‘content themes’ show similar results, the change in affective tone over the years has been both significant and
striking. A sample of results from three years of the twenty-two year period is then qualitatively explored to demonstrate
to the reader the connection between the quantitative results of the Dictionary and the qualitative effect of the article’s word use and phrasing. The paper ends with a review of the technique’s success,
implications for policymaking and public dialogue, and avenues for future use. 相似文献

The current study examined the effects of motivating operations on problem behavior and academic engagement for 2 students with autism. Classroom sessions were preceded by periods in which the participants had access or no access to the items functionally related to their problem behavior. Results suggested that presession access may result in lower levels of problem behavior and higher levels of academic engagement during classroom instruction. 相似文献

In the present study, we examined a bidimensional model of acculturation (which includes both heritage and U.S. practices, values, and identifications) in relation to hazardous alcohol use, illicit drug use, unsafe sexual behavior, and impaired driving. A sample of 3,251 first- and second-generation immigrant students from 30 U.S. colleges and universities completed measures of behavioral acculturation; cultural values (individualism, collectivism, and self-construal); ethnic and U.S. identity; and patterns of alcohol and drug use, engagement in potentially unsafe sexual activities, and driving while (or riding with a driver who was) intoxicated. Results indicate that heritage practices and collectivist values were generally protective against health risk behaviors, with collectivist values most strongly and consistently protective. Nonetheless, heritage identifications were positively associated with sexual risk taking for Hispanics. U.S. practices, values, and identifications were not consistently related to risk behavior participation. Results are discussed in terms of bidimensional approaches to acculturation, the immigrant paradox, and implications for counseling practice. 相似文献

Two individuals acting together to achieve a shared goal often have an emergent set of afforded behavioral possibilities that may not easily reduce to either acting alone. In a series of experiments we examined the critical boundaries for transitions in behavior for individuals walking through an aperture alone or alongside another actor as a dyad. Results from experiment 1 indicated that an intrinsically scaled critical boundary for behavioral transitions was different in individuals than in dyads performing a similar task. Experiment 2 demonstrated that observers are perceptually sensitive to the difference in action parameters for the dyad, while still maintaining perceptual sensitivity about the boundaries of action relative to individuals. In experiment 3, we determined that observers' perception of critical action boundaries for individuals and dyads has a similar informational basis (eye-height scaling). In experiment 4, we demonstrated that observers were able to perceive critical action boundaries for other dyads independently of membership. Together, these results suggest that individuals are sensitive to the affordances related to a joint action, and that this process may not entirely reduce to the perception of the affordances for each individual. 相似文献

This article comments on Lachance-Grzela and Bouchard (2010), which reviews research published 2000–2009 on the division of household labor. I argue that while Lachance-Grzela and Bouchard summarize the general state of knowledge on this topic, their review highlights what is missing from research on the division of household labor. To move beyond questioning why women perform the majority of housework requires a different set of questions, using a variety of data collection and analysis techniques, and a clear eye toward broader social theory. 相似文献

This investigation tested for gender effects in conflict behaviors by examining the ratings made by the bosses, peers, and subordinates of over 2,000 working adults participating in leadership development programs conducted in the U.S.; the effects of two confounding factors—age and organizational status—were controlled in all analyses. Consistent with predictions derived from a gender role analysis, women were rated as significantly more likely to engage in almost every constructive behavior. Also as predicted, men were rated as more likely to engage in active destructive behaviors. Rater gender had no effect for peers and subordinates, but female bosses made more positive ratings of targets than male bosses. In general, bosses rated targets somewhat higher on passive responses. 相似文献

Rapamycin, an inhibitor of the mammalian target of rapamycin (mTOR) kinase, has attracted interest as a possible prophylactic for post-traumatic stress disorder (PTSD)-associated fear memories. We report here that although rapamycin (40 mg/kg, i.p.) disrupted the consolidation and reconsolidation of fear-potentiated startle paradigm to a shock-paired context, it did not disrupt startle increases to a 4-sec odor cue, even though post-training increases in amygdala mTOR activity were prevented by rapamycin (also 40 mg/kg, i.p.). Thus, while rapamycin may prove useful in retarding the development of some PTSD-associated memories, its relative ineffectiveness against cued fear memories may limit its clinical usefulness. 相似文献

Those who commit crime on a grand scale, numbering their victims in the thousands, seem to pose a special problem both for
consequentialist and for non-consequentialist theories of punishment, a problem the International Criminal Court makes practical.
This paper argues that at least one non-consequentialist theory of punishment, the fairness theory, can provide a justification
of punishment for great crimes. It does so by dividing the question into two parts, the one of proportion which it answers
directly, and the other of ‘anchoring points’ which it assigns to a broader theory of enforcement (which may have a non-consequentialist
or consequentialist version). 相似文献
