Women are particularly vulnerable to anxiety and depressive disorders. This greater vulnerability has been partly attributed to post-pubertal sex hormone fluctuations, estradiol and progesterone, as well as gender-specific tendencies to engage in maladaptive forms of emotion regulation, particularly rumination. To date, no research has investigated whether sex hormones are associated with emotion regulation in women. In the present study, 61 women participated in a sad mood induction task, involving the viewing of an emotive film. Negative affect was assessed immediately and following recovery, along with self-reported use of rumination, reappraisal, and suppression. Serum levels of estradiol and progesterone were assessed through a blood sample taken at the end of the experiment. Regression analyses were used to examine the relationship between serum hormones and self-reported emotional regulation strategy use, and between serum hormones and the impact of these strategies on negative affect. Estradiol levels positively predicted rumination, but not suppression or reappraisal use. Moreover, estradiol and progesterone interacted with emotion regulation strategies to predict negative affect following the sad mood induction. Reappraisal was associated with greater negative affect only in women with high estradiol, and in women with high progesterone. Conversely, rumination was associated with greater negative affect only in women with low estradiol. Together, these results suggest that sex hormone concentration may be an endogenous contextual factor that is associated with the selection and consequences of emotion regulation strategies in women.
This paper describes how fault tree analysis may be used to calculate the probability that people will detect fires in hospitals. In particular, study is made of the contribution of patients and varying staff numbers. Their contribution is based on new data gathered by shadowing staff and assessing wards. This data showed that staff spent 75 per cent of their time undertaking duties that would facilitate the detection of fires, in locations where they could observe more than 30 per cent of the ward. This provides a greater understanding why the historical data indicates that staff observation of fire is so effective. It is concluded that fault tree analysis offers a useful tool which can inform decisions regarding the costbenefit of fire protection measures.KEY WORDS Fault tree analysis, fire detection, hospital fire safety, observation by people, probability.
This chapter is centred on a case study on brain injury after cardiac arrest. This topic is one of the key challenging areas in critical care medicine and one that all intensive care staff will encounter. The chapter is based on a detailed case history, ensuring clinical relevance, together with relevant images, making this easily relatable to daily practice in the critical care unit. The chapter is punctuated by evidence-based, up-to-date learning points, which highlight key information for the reader. Throughout the chapter, a topic expert provides contextual advice and commentary, adding practical expertise to the standard textbook approach and reinforcing key messages.
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.
