The Welfare to Work Transition in the United States: Implications for Work-Related Learning

This paper summarizes the legislation upon which the current welfare-to-work transition in the United States is based and describes characteristics of the former welfare population from which various tiers of employment options have emerged: unsubsidized-employed workers, subsidized-employed workers, subsidized-unemployed recipients, and unsubsidized-unemployed individuals. It also discusses current program emphases, and presents a format for directions for future program development which includes academic programs, situated cognition programs, integrated literacy/occupational skills programs, and integrated literacy/soft skills training.     

The Introduction of Computer‐based Testing on an Engineering Technology Course

The current situation in higher education is one of increasing student numbers with a decreasing unit of resource. To help cope with this situation lecturers are exploring the possibility of using non‐traditional methods in some aspects of their work. One possibility is to apply new technology in the assessment of students. This paper presents a controlled comparison between traditional paper‐based tests and those using a computer. It is concluded that the new technique is acceptable to students and produces results with no deterioration in their validity; it also has great potential for the saving of staff time.     

Intercultural crisis communication: examining the experiences of crisis sojourners

The concept of the sojourner has been studied in a variety of contexts, such as business, education, and international aid. However, there is as yet no communication research on the topic of the crisis sojourner. Consequently, the goal of this study was to explore experiences of crisis sojourners to determine what they perceive as effective and ineffective communication in intercultural settings. In-depth interviews were conducted with 20 emergency responders who deploy internationally following events such as the earthquake in Haiti or the Fukushima meltdown. Results showed crisis sojourners from this population were aware of cultural differences and highly alert to the emotional and physical pain of those they were attempting to assist. Furthermore, they were cognizant of cultural norms and had a strong desire to respect local values. These results yield implications for individuals who work as crisis sojourners, and questions about the need for intercultural crisis communication education for those who face such situations routinely.     

A study of untrained models for multimodal information retrieval

Operational multimodal information retrieval systems have to deal with increasingly complex document collections and queries that are composed of a large set of textual and non-textual modalities such as ratings, prices, timestamps, geographical coordinates, etc. The resulting combinatorial explosion of modality combinations makes it intractable to treat each modality individually and to obtain suitable training data. As a consequence, instead of finding and training new models for each individual modality or combination of modalities, it is crucial to establish unified models, and fuse their outputs in a robust way. Since the most popular weighting schemes for textual retrieval have in the past generalized well to many retrieval tasks, we demonstrate how they can be adapted to be used with non-textual modalities, which is a first step towards finding such a unified model. We demonstrate that the popular weighting scheme BM25 is suitable to be used for multimodal IR systems and analyze the underlying assumptions of the BM25 formula with respect to merging modalities under the so-called raw-score merging hypothesis, which requires no training. We establish a multimodal baseline for two multimodal test collections, show how modalities differ with respect to their contribution to relevance and the difficulty of treating modalities with overlapping information. Our experiments demonstrate that our multimodal baseline with no training achieves a significantly higher retrieval effectiveness than using just the textual modality for the social book search 2016 collection and lies in the range of a trained multimodal approach using the optimal linear combination of the modality scores.
