The Concept of Record in Interactive, Experiential and Dynamic Environments: the View of InterPARES*

This article presents the concept of electronic record as articulated by the first phase of the InterPARES (International research on Permanent Authentic Records in Electronic Systems) Project (1999–2001) and discusses it in light of the findings of the second phase of the Project (2002–2006). While InterPARES 1 focused on records produced and/or maintained in databases and document management systems, InterPARES 2 examined records produced and/or maintained in interactive, experiential and dynamic environments. The authors describe the characteristics of these environments and of the entities found in them in the course of case studies conducted on systems used for carrying out artistic, scientific and e-government activities, and propose the new concept of record that InterPARES 2 is eleborating, which expands on that formulated by InterPARES 1.The authors would like to thank InterPARES 2 research assistant Randy Preston for his careful editing and constructive criticisms. Some of his suggestions have been incorporated in the text of this article.

The impact of coworker support and stigma on breastfeeding after returning to work

This study assessed the impact of coworker support on lactating mothers’ breastfeeding self-efficacy after maternity leave. A cross-sectional survey of 1000 working adults assessed effects of perception of fairness, coworkers’ support for breastfeeding colleagues, and ick response on willingness to help mothers needing breaks to pump breastmilk at work. The study also examined how coworker support affected mothers’ self-efficacy to continue breastfeeding. One out of four coworkers showed moderate to strong stigma, saw breaks to pump breastmilk as unfair, and showed less intention to help new mothers. These results suggest that while the majority of coworkers are generally supportive, lactating women are likely to encounter disapproving coworkers who may discourage them from continuing to breastfeed. The data showed that the majority of organizations included in this study have only passively fostered mother-friendly workplaces and could do more to encourage employees to be supportive of lactating colleagues.
