The structural behaviour in fire of a cold-formed steel portal frame having semi-rigid joints

This paper describes a non-linear finite element study into the effects of elevated temperature on a cold-formed steel portal frame having semi-rigid joints. Numerical modelling was carried out using ABAQUS finite element analysis software with shell elements used to capture localised buckling effects. Results for the ambient shell models are compared against previous full-scale tests. Material properties are taken from the literature, in order to predict the behaviour of the frame at elevated temperature. The results of finite element beam models are compared against those of shell models to enable comparison. At elevated temperature, shell models are shown to detect failure much earlier within the fire. Therefore shell models are recommended for such studies, for a conservative approach

Adults’ Readiness to Learn and Skill Acquisition and Use: An Analysis of PIAAC

This study examined the relationship between adults’ readiness to learn (RtL) and skill acquisition and use in the US sample of the PIAAC. RtL showed significant effects on each of the observed skill use outcomes. It was the strongest predictor of reading and writing skill use at home

Terms of Engagement: Adults’ Experience in Higher Education

National Survey of Student Engagement (NSSE) data were re-analyzed to look for differences between traditional and nontraditional-age students. Surprisingly, no significant differences were found for five NSSE Benchmarks, including Supportive Campus Environment. Differences were found in subsequent analysis of two scales of academic engagement identified through follow-up factor analysi

Differences between US and German adults in native-born and migrants’ participation in volunteering as a dimension of civic engagement

We examine civic engagement among immigrants and native-born adults in the United States (U.S.) and Germany, operationalized in this study as voluntary work or volunteerism. Data for the analyses are drawn from the PIAAC. Germany and the U.S. were selected from the countries participating in PIAAC initial data collection in 2012 as two large OECD countries with different histories of immigration and responses to migrants. In Germany, native-born individuals showed greater volunteerism than immigrants (β = 0.119, p \u3c .001) while in the U.S., no significant difference was apparent by immigration status (β = 0.031, p = .133). These results are discussed in the paper relative to existing research literature and implications for adult education are suggested

The Freshman, vol. 5, no. 17

The Freshman was a weekly, student newsletter issued on Mondays throughout the academic year. The newsletter included calendar notices, coverage of campus social events, lectures, and athletic teams. The intent of the publication was to create unity, a sense of community, and class spirit among first year students
