As the complexity of the challenges presented by our interactions with our planet continues to grow, we must develop new modes
of knowledge production. In these modes, distinctions between multidisciplinary and inter-disciplinary activities and processes
have renewed importance. There are at least two distinct types of interdisciplinary activities distinguished by the disciplinary
breadth they attempt to bridge. In the narrow case, reductionist processes reveal a common underlying principle or process
which can serve as a Rosetta stone. In the broad case, no such common arbiter exists. Investigators must develop integrating
vocabulary in the context of the full breadth of their work.
His primary activities are the fostering of university-wide interdisciplinary research and curriculum programs focused on
global change with the goal of developing Columbia into a world leader in issues related to global stewardship. 相似文献

This paper examines college students' attributions about suicide as a function of gender and context (athletic vs. relationship failure). Results indicated that male athletes who suicided were considered more emotionally well-adjusted compared to males who suicided because of a relationship failure and all females. Male and female athletes who suicided were seen as more competent and less distressed compared to those who suffered a failed relationship. Females were also seen as more distressed compared to males. These results are discussed in terms of a positive bias toward athletes in our society as well as gender stereotypes. Implications of these findings as well as methodological limitations are discussed. 相似文献

We present a study of the accuracy, consistency, and speed of word naming in a dyslexic boy, JM, who has severe impairments in the ability to use sub-lexical, phonological reading strategies. For words that he can recognise, JM's naming latencies do not differ from those of control subjects matched for reading age, and he is generally consistent from one occasion to the next. He can also match printed homophones with their definitions--a skill that requires access to well-specified orthographic representations. The data are interpreted as evidence for the creation of efficient recognition devices for words within JM's sight vocabulary. However, he shows a continuing inability to use phonological decoding strategies to deal with words that he cannot recognize by sight. Overall we argue our results pose problems for stage models of reading development, and that they may best be interpreted within a connectionist framework of the development of word recognition skills. 相似文献

In the present paper, I critique the use of the retrospective method when it is used as a proxy for actual longitudinal data on personality development. Studies on the constructive nature of memory cast strong doubts about the meaning of retrospective data. There are good reasons, both theoretical and empirical, to distrust the accuracy of such recall concerning parenting, whether recalled by parents, children, or siblings. Instead of using the method as a shortcut to developmental data, studies examining individual differences in accuracy and distortion and the factors that moderate them may inform us of the various meanings of retrospective data. 相似文献

Behavioral momentum refers to the tendency for behavior to persist following a change in environmental conditions. The greater the rate of reinforcement, the greater the behavioral momentum. The intervention for noncompliance consisted of issuing a sequence of commands with which the subject was very likely to comply (i.e., high-probability commands) immediately prior to issuing a low-probability command. In each of five experiments, the high-probability command sequence resulted in a “momentum” of compliant responding that persisted when a low-probability request was issued. Results showed the antecedent high-probability command sequence increased compliance and decreased compliance latency and task duration. “Momentum-like” effects were shown to be distinct from experimenter attention and to depend on the contiguity between the high-probability command sequence and the low-probability command. 相似文献
