Social connection is important for people’s health and well-being. Social isolation arising from a lack of meaningful connection with others can result in deterioration of well-being with negative consequences for health. For people living with multiple long-term conditions, the building and maintaining of social connection may be challenging. The aim of this study was to explore with people with long-term conditions how they perceive they maintain and develop social connections. We undertook semi-structured interviews with seventeen adults, and analyzed the data for themes. Themes were “Meaningful connection”, “Wherewithal for social connection” and “Impact of a major change in life course”. The findings suggest that social connection is valued, and facilitates meaningful ways to reciprocate support with others, thus enabling access to knowledge and resources for better health and well-being. However, people with long-term conditions can experience challenges to developing and maintaining social connectedness after a major change in life course. We suggest that healthcare providers are well placed to facilitate ways for people with long-term conditions to socially connect with others in their neighbourhood and community, and that this in particular be attended to after a major life change.
Historically, performance has been the most important feature when optimizing computer hardware. Modern processors are so highly optimized that every cycle of computation time matters. However, this practice of optimizing for performance at all costs has been called into question by new microarchitectural attacks, e.g. Meltdown and Spectre. Microarchitectural attacks exploit the effects of microarchitectural components or optimizations in order to leak data to an attacker. These attacks have caused processor manufacturers to introduce performance impacting mitigations in both software and silicon.To investigate the performance impact of the various mitigations, a test suite of fortyseven different tests was created. This suite was run on a series of virtual machines that tested both Ubuntu 16 and Ubuntu 18. These tests investigated the performance change across version updates and the performance impact of CPU core number vs. default microarchitectural mitigations. The testing proved that the performance impact of the microarchitectural mitigations is non-trivial, as the percent difference in performance can be as high as 200%. iv ACKNOWLEDGMENTS My thanks to: My husband Chad, for supporting me through the trials and tribulations of both my bachelors and masters degrees. Doing this alone would have been far more difficult, and I would not have flown as high.My parents, Nikki and Tommy, for their support, as well as giving me the desire to go into this field in the first place.Dr. Lupo, both for being a great advisor on this project, and for walking back the feature creep I attempted to introduce every meeting.Mr. Scovil, whose initial classes and teaching gave me the foundation to get this far.All of my friends, who either helped me study throughout college or just put up with my whining.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
