Robert Stalnaker has argued that mathematical information is information about the sentences and expressions of mathematics. I argue that this metalinguistic account is open to a variant of Alonzo Church's translation objection and that Stalnaker's attempt to get around this objection is not successful. If correct, this tells not only against Stalnaker's account of mathematical truths, but against any metalinguistic account of truths that are both necessary and informative. 相似文献

A two‐study investigation was designed to examine the role of job type (i.e. fit of political skill to work context) as a contextual moderator of the political skill–job performance relationship. Specifically, it was hypothesised that political skill operates most effectively in enterprising job contexts, and thus is most predictive of job performance in such contexts, but political skill would demonstrate no relationship with job performance in job contexts that did not emphasise interpersonal interaction and effectiveness. In Study 1, enterprising job demands interacted with political skill to affect job performance. That is, political skill positively and significantly predicted job performance in enterprising job contexts, as hypothesised. Study 2 selected one specific job context (i.e. insurance sales) high in enterprising job demands, and hypothesised that political skill would significantly predict objective measures of insurance sales (i.e. sales volume, performance‐based income, performance‐based commission rate, and performance‐based status). The results demonstrated significant predictive effects of political skill (i.e. beyond age, sex, education level, tenure on the job, and experience in sales) on all four measures of sales performance. Contributions and implications of this research, strengths and limitations, and directions for future study are discussed. 相似文献

Methods for the identification of differential item functioning (DIF) in Rasch models are typically restricted to the case of two subgroups. A boosting algorithm is proposed that is able to handle the more general setting where DIF can be induced by several covariates at the same time. The covariates can be both continuous and (multi‐)categorical, and interactions between covariates can also be considered. The method works for a general parametric model for DIF in Rasch models. Since the boosting algorithm selects variables automatically, it is able to detect the items which induce DIF. It is demonstrated that boosting competes well with traditional methods in the case of subgroups. The method is illustrated by an extensive simulation study and an application to real data. 相似文献

The present study was designed to examine the relationships between students’ character strengths, school-related affect, positive school functioning (i.e., motivation to learn, interest, and engagement at class), and school achievement following the “engine model of well-being” that is focusing on inputs (e.g., personality traits), processes (e.g., moods, emotions), and outcomes (e.g., engagement, accomplishments) within the context of well-being research. A sample of 196 children completed the Values in Action Inventory of Strengths for Youth, which assesses 24 character strengths, and the PANAS-C that assesses school-related positive and negative affect. Additionally, homeroom teachers rated students’ positive school functioning (i.e., motivation, engagement, and interest at school) and their overall school achievement. The character strengths of zest, love of learning, perseverance, and social intelligence showed the strongest positive correlations with school-related positive affect. Teamwork, hope, self-regulation, and love were substantially negatively correlated with school-related negative affect. Certain character strengths showed positive relationships with positive school functioning and overall school achievement. A path model, testing the “engine model of well-being”, found—additionally to direct effects—indirect relationships between character strengths and positive school functioning (through school-related positive affect), which in turn leads to higher school achievement. The presented findings show character strengths as meaningful resources in the schooling context. Character strengths emerge to be crucial for students to experience school-related positive affect, which in turn supports students’ positive school functioning and their overall school achievement. The results demonstrate the complex interplay between students’ personality traits, affect, school functioning, and achievement at school. 相似文献

We consider whether and under what conditions it is morally illicit to profit from poverty. We argue that when profit counterfactually depends on poverty, the agent making the profit is morally obliged to relinquish it. Finally, we argue that the people to whom the profit should be redirected are those on whom it counterfactually depends. 相似文献

Bystanders observing a cyberbullying incident do not always intervene in favor of the victim. We argue that gender stereotypic perceptions of female versus male victims contribute to the differential reactions of bystanders to cyberbullying incidents. Results of a scenario-based experiment show that participants with moderate or high levels of sexist attitudes are more empathic toward a female victim of workplace cyberbullying. Consequently, a female victim is more likely to receive help. Female victims are less likely to be attributed blame if the perpetrator is male. The results imply that male victims of cyberbullying are marginalized by their social environment. 相似文献
