The Impact

In this paper, the impact of high wind power and photovoltaics penetration on the dynamic behavior of an island power system like one operates in Crete is investigated. Several simulations were performed leading to the fact that it is possible to achieve higher level of renewable energy sources penetration without significant dynamic security problems, if power units spinning reserve exists and the corresponding control systems have a sufficiently fast response.

Purpose The purpose of this study was to investigate the perceptions of speech-language pathologists (SLPs) regarding their academic preparation and current confidence levels for providing dysphagia services, and the relationship between their perceptions of graduate school preparation and their current levels of confidence. Method This study utilized an online survey to gather information from 374 American Speech-Language-Hearing Association–certified SLPs who currently provide dysphagia services in the United States. Surveys were primarily distributed through American Speech-Language-Hearing Association Special Interest Group forums and Facebook groups. The anonymous survey gathered information regarding SLPs' perceptions of academic preparation and current confidence levels for providing dysphagia services in 11 knowledge and skill areas. Results Findings indicated that more than half of respondents did not feel prepared following their graduate academic training in five of the 11 knowledge and skill areas related to dysphagia service delivery. However, about half of respondents indicated they were currently confident about their ability to provide services in eight of the 11 knowledge and skill areas. Findings also indicated that their current confidence levels to provide dysphagia services were significantly higher than their perceptions of preparation immediately following graduate school. However, no significant relationships were found between respondents' self-reported current confidence levels and their perceptions of the adequacy of their academic preparation. Conclusions Despite SLPs' low perceptions of the adequacy of their graduate preparation for providing dysphagia services in specific knowledge and skill areas immediately following graduation, they reported high confidence levels with respect to their actual service delivery. Implications of these findings are discussed.
