The effects of self-determination vs. teacher-determination of timeout duration on disruptive behavior were investigated in a group of 15 students in a special classroom who had learning disabilities and/or behavior problems. There were five phases to the study: In a repeated measures design each subject received timeout for 5 minutes, no timeout, 5 minutes timeout, selfdetermined timeout duration, and student = teacher-determined timeout duration. The overall effect of timeout was to reduce significantly the rate of disruptive behavior. The effects of various timeout conditions did not differ, indicating self-management of timeout duration was just as effective as when the teacher set the timeout duration.  相似文献

This study examined Library and Information Science (LIS) undergraduate students’ career aspirations in entrepreneurship and self-employment opportunities. A total of 155 students constituted the sample for the study. A self-designed questionnaire was used for the collection of data. The results demonstrate that 20.3% aspire to set up a small business, 39.2% prefer company employment, 30.4% prefer self-employment, and 20.3% prefer government employment. Forming partnerships, loans from banks and friends, grants from private foundations and personal savings and cash, private stock, and angel investors were identified as sources of funding. Careers available in LIS were identified to include librarian, abstracter, lecturer, web designer, database manager, archivist, information broker, publisher, and researcher. Hindrances to careers in entrepreneurship and self-employment were identified to include lack of access to financial services, access to physical infrastructure, and basic services. The study makes recommendations based on the findings.  相似文献

ABSTRACT

This study examines the patterns of news engagement among news consumers with different political affiliation and cultural background. We use computational methods and data from Twitter in a cross-country comparison of engagement with six online news sources in Australia and South Korea. For our analysis, we used a subset of Twitter users who retweeted at least one political story during the period of collection, and for whom we were able to predict political affiliation using correspondence analysis and data on Twitter follower ties to politicians. We find that right-wing Australian retweeters are more intense in their news engagement, compared with their left-wing counterparts, whereas in South Korea it was the opposite. Australian right-wing political retweeters have more diverse information sources, while there was no difference in information diversity between the right and left in South Korea. We discuss how the political situation in South Korea at the time of data collection may have affected our analysis. We emphasise the methodological contributions of our research and its connection to on-going research into the behavioural foundations of ‘filter bubbles’.  相似文献
