Little is known about how social media are used in cancer care. We conducted a systematic review of the use and taxonomy of social media in cancer-related studies, in PubMed, Web of Knowledge, CINAHL, and Google Scholar. We located 1350 articles published through October 2013; 69 met study inclusion criteria.
Early research (1996–2007) was predominantly descriptive studies of online forums. Later, researchers began analyzing blogs, videos shared on YouTube, and social networking sites. Most studies (n = 62) were descriptive, and only 7 reported intervention studies published since 2010.
Future research should include more intervention studies to determine how social media can influence behavior, and more empirical research is needed on how social media may be used to reduce health disparities.
The purpose of our work is to investigate the export strategy of international business by explicitly comparing exporting firms with non-exporting ones. This task has been undertaken by having recourse to a very large sample with more than 55,000 registered Spanish enterprises from all commercial sectors. Using this sample, we try to demonstrate that exporters and non-exporters belong to different strategic groups, with different profit levels. The existence of three kinds of barriers (managerial, organisational and external) constrains migration of non-exporting enterprises to the exporting group. However, the conclusions herein presented point at some ways of avoiding these barriers.
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.
