Data were collected from students in grades three to eight (N = 377) in order to identify the determinants of their intentions to perform laboratory and nonlaboratory science activities. Fishbein and Ajzen's theory of reasoned action was used as the basis for the study. The theory posits that the immediate determinant of behavior is intention. Intention is determined by the weighted attitude toward the behavior and the weighted subjective norm. Attitude toward behavior and subjective norm are determined by combinations of beliefs, evaluations, and motivations to comply. Cores of salient beliefs related to attitude toward laboratory and nonlaboratory behaviors and cores of salient beliefs related to subjective norm for laboratory and nonlaboratory behaviors were identified. Hypotheses generated from the theory were confirmed. Attitude toward behavior and subjective norm explained significant amounts of variance in behavioral intention for both laboratory and nonlaboratory behaviors. Attitude toward behavior had a greater relative weight than subjective norm for both laboratory and nonlaboratory. The correlations between adjacent constructs in the theoretical model were significant in all cases. 相似文献

Despite a long history of rich theoretical work on provenance, empirical research regarding users?? interactions with and judgments based upon provenance information in archives with scientific data is extremely limited. This article focuses on the relationship between provenance and credibility (i.e., trustworthiness and expertise) for scientists. Toward this end, the authors conducted semi-structured interviews with seventeen proteomics researchers who interact with data from ProteomeCommons.org, a large online repository. To analyze the resulting interview data, the authors apply Brian Hilligoss and Soo Young Rieh??s empirically tested theoretical framework for user credibility assessment. Findings from this study suggest that together with other information provided in ProteomeCommons.org and subjects?? own experiences and prior knowledge, provenance allows users to determine the credibility of datasets. Implications of this study stress the importance of the archival perspective of provenance and archival bond for aiding scientists in their credibility assessments of data housed in scientific data repositories. 相似文献
