Intentions are an important concept in Artificial Intelligence and Cognitive Science. We present a formal theory of intentions and beliefs based on Discourse Representation Theory that captures many of their important logical properties. Unlike possible worlds approaches, this theory does not assume that agents are perfect reasoners, and gives a realistic view of their internal architecture; unlike most representational approaches, it has anobjective semantics, and does not rely on anad hoc labeling of the internal states of agents. We describe a minimal logic for intentions and beliefs that is sound and complete relative to our semantics. We discuss several additional axioms, and the constraints on the models that validate them. 相似文献

A 21-item 4-point Alienation Scale (Kureshi & Dutt, 1979) in Hindi was administered to a randomly selected group of 400 educated youth equally divided into: (1) technically educated unemployed, (2) non-technically educated unemployed, (3) technically educated employed, and (4) non-technically educated employed. This scale aimed to ascertain in these subjects comparative degrees of feeling of alienation and its dimensions. Results of statistical comparison revealed that the technically and the non-technically educated unemployed youth, as compared to their employed counterparts, evinced relatively a greater vulnerability to the feeling of alienation and its dimensions, though the latter were also moderately susceptible in this regard. Further, it was found that the technically educated unemployed youth were more prone to alienation and its dimensions and the non-technically educated employed youth were the least affected, with the non-technically educated unemployed and the technically educated employed youth in second and third places respectively. The study also indicated a close association between different dimensions of alienation, both with each other and with the total scale scores. 相似文献
The present study was undertaken to explore ways projective arid nonprojective verbal measures of achievement motivation elicit comparable and dissimilar responses in a "Third World" sample of entrepreneurs as a test of McClelland's theory of economic growth. Results were generally consistent with the theory of achievement motivation, and suggested that high scores on n Ach were associated with high rates of industrial and agricultural output; low scores were associated with static or declining business. TAT measurement was the best predictor in that it correlated 0.68 and 0.48 with agricultural and industrial production. Results further lend support to past findings: namely, that Various achievement measures appear to be measuring dissimilar constructs. 相似文献
As a result of persisting stigma, transgender people experience vastly higher rates of harassment, violence, and mental health issues compared to cisgender people. The current study experimentally evaluated a computer-mediated intergroup contact strategy, called E-contact, to reduce transgender stigma. E-contact is a synchronous, cooperative, goal-directed online interaction which is informed by Allport’s intergroup contact theory. In total, 114 cisgender, heterosexual, Australian undergraduates and community members (83 women, 31 men) were randomly allocated to E-contact with an online confederate who either disclosed that they were a transgender woman or a cisgender woman. Following the online interaction, participants then completed measures assessing prior transgender contact and transgender stigma. The findings revealed that transgender E-contact reduced stigma for cisgender men whereas it had no impact on women’s already lower levels of stigma. These novel findings have important implications for researchers, policymakers and counsellors interested in developing transgender stigma reduction interventions by (a) highlighting the importance of transgender contact for those individuals with low or poor prior contact and (b) targeting prejudice-prone populations, such as men, who stand to gain the most from such cooperative, goal-directed interventions.

The authors describe the ways in which the Multicultural and Social Justice Counseling Competencies (MSJCC; Ratts, Singh, Nassar-McMillan, Butler, & McCullough, 2015) can be viewed from a human rights framework and as the latest iteration in the long history of the multicultural and social justice counseling competency movement. MSJCC implementation and integration are explored, and recommendations for innovating the MSJCC are described. 相似文献
