The usefulness of a baseline record is often compromised by extraneous events in the natural environment that artificially intervene to prevent the performance of a specific target behavior. To attenuate this problem, a simple ratio adjustment procedure was suggested that compares the observed response frequency with a maximum possible frequency for each observation period. This ratio is then transformed into a response percentage with a more general predictive value for the behavior modification practitioner. 相似文献

In the decade since the founding of WikiLeaks, no non-leak-related issue has dominated coverage of the organization more than the August 2010 allegations made by two women in Stockholm against WikiLeaks founder Julian Assange. This case has been addressed on the WikiLeaks Twitter feed on a consistent basis over the past 6 years. The tweets from WikiLeaks to millions of followers constitute a form of popular communication where a broad—albeit somewhat prefigured—audience is targeted using an open social media platform. With this audience in mind, I analyze the use of Twitter by WikiLeaks to address the 2010 rape allegations against Assange (and the subsequent follow-on events after those allegations), with a particular focus on two issues: (a) the framing by WikiLeaks of the allegations, Sweden, rape, and feminism; and (b) how the sources (links) used in those tweets to back up claims should be seen as part of the general framing process. 相似文献

The article tests a couple of hypotheses relating to markets where demand is not taken as a given, but subject to sophisticated
and encompassing price-building strategies. The study uses a data set that provides quoted dealer prices for medium-sized
works of 100 leading visual artists from 1970 to 2004. These data are compared with auction price results for works by the
same artists. The study reports significant discrepancies with respect to the relationship between the age of artists and
prices paid for their works in the two markets, and with respect to general price developments in the two markets as measured
by indices.

Referees in German first-league soccer games do not award as many yellow cards in the beginning of a game as should be statistically expected. One explanation for this effect is the concept of game management (Mascarenhas, Collins, & Mortimer, 2002). Alternatively, the consistency model (Haubensak, 1992) explains the effect as a necessity of the judgment situation: Referees need to calibrate a judgment scale, and, to preserve degrees of freedom in that scale, they need to avoid extreme category judgments in the beginning (i.e., yellow cards). Experiment 1 shows that referees who judge scenes in the context of a game award fewer yellow cards than referees who see the same scenes in random order. Experiment 2 shows the combined influence of game management (by explicitly providing information about the game situation) and calibration (early vs. late scenes in the time course of a game). Theoretical implications for expert refereeing and referee training are discussed. 相似文献

Clutch performance is improved performance under pressure. However, little research has examined the psychological state experienced by athletes in these situations. Therefore, this study qualitatively examined the subjective experience underlying clutch performance across a range of sports (e.g., team, individual) and standards (Olympic to recreational athletes). Sixteen athletes (Mage = 27.08 years; SD = 6.48) took part in in-depth, semi-structured interviews primarily after an exceptional performance (M = 4.38 days later; SD = 3.14). Data were analysed inductively and thematically. Clutch states involved 12 characteristics, including heightened and deliberate concentration, intense effort, and heightened awareness, which distinguished the experience of clutch from other optimal psychological states such as flow. Other characteristics, such as perceptions of control, were also reported and supported previous experimental research on clutch. These findings present in-depth qualitative insights into the psychological state underlying clutch performance, and are discussed in relation to the existing literature on optimal psychological states in sport. 相似文献

Understanding the social consequences of major soccer events is important for social science researchers and policy-makers alike. On the one hand, socially integrative effects are ascribed to these events. On the other hand, they are suspected of increasing the devaluation of minorities and disadvantaged groups. Sociological theories in a Durkheimian tradition suggest that the emotional entrainment that goes along with football-related rituals might play a role. We thus investigated the effects of the World Cup 2010 on the derogation of minorities and disadvantaged groups in Germany and hypothesized that the emotional entrainment is a predictor of changes in derogation. Results of our naturalistic study show significant increases in derogative attitudes after the World Cup. Contrary to our expectations, emotional entrainment is not associated with this increase. We discuss possible alternative explanations, in particular the influence of public discourse. 相似文献

The paper uses Ludwig Wittgenstein's theories about the relationship between thought, language, and objects of the world to explore the assumption that OO-thinking resembles natural thinking. The paper imports from research in linguistic philosophy to computer science education research. I show how UML class diagrams (i.e., an artificial context-free language) correspond to the logically perfect languages described in Tractatus Logico-Philosophicus. In Philosophical Investigations Wittgenstein disputes his previous theories by showing that natural languages are not constructed by rules of mathematical logic, but are language games where the meaning of a word is constructed through its use in social contexts. Contradicting the claim that OO-thinking is easy to learn because of its similarity to natural thinking, I claim that OO-thinking is difficult to learn because of its differences from natural thinking. The nature of these differences is not currently well known or appreciated. I suggest how explicit attention to the nature and implications of different language games may improve the teaching and learning of OO-modeling as well as programming. 相似文献
