Recent research indicates that happiness, or affective well-being, is related primarily to the frequency, not to the intensity, of positive affect (PA). The question arises as to why intense positive affect (PI) is not a larger contributor to subjective well-being. Whether processes that yield PI also produce intense negative affect was examined.

STUDY OBJECTIVE To investigate the relative contributions of the corpus luteum (CL) and the placenta to the circulating levels of relaxin during pregnancy. PATIENTS Forty-one patients in whom pregnancy had been achieved by ovum donation. RESULTS Relaxin was not detected in the serum of 36 patients; in the remaining 5, although it was detectable, the(More)
OBJECTIVE To assess the relation between peak active (above baseline) head-to-cervix force (paHCF) and peak active (above baseline) intrauterine pressure (paIUP) in labour, and to compare the relation between labours progressing well and ending in vaginal delivery and those labours progressing slowly and ending in caesarean section. DESIGN Prospective(More)
In this study, the effect of superovulation on the circulating levels of insulin-like growth factor binding protein-1 (IGFBP-1) has been investigated. IGFBP-1 levels were measured in singleton pregnancies achieved either naturally (n = 203) or following superovulation, in-vitro fertilisation and embryo transfer (IVF-ET) with either pituitary desensitisation(More)
OBJECTIVES To determine the perinatal outcome of fetuses who had birthweights less than that expected from early third trimester ultrasound scanning. DESIGN Retrospective estimation of centile fetal weight at early third trimester ultrasound scanning compared with actual centile birthweight corrected for gestational age, parity and sex. SETTING Teaching(More)
OBJECTIVE To investigate the relation between the rise in intrauterine pressure and rise in fetal head to cervix force in normal, slow and induced labour. DESIGN Prospective observational study. SETTING The labour ward of a London teaching hospital. PARTICIPANTS Forty patients were recruited from the antenatal clinic and labour ward of a West London(More)
The factors that determine the circulating levels of relaxin during pregnancy have been investigated by comparing the plasma levels of relaxin throughout pregnancy in women who became pregnant spontaneously (singleton, n = 240) or following superovulation (singleton and multifetal pregnancies (two to ten conceptuses), n = 83). Some of the women with(More)
Uterine activity may be monitored by methods ranging from gentle palpation of the uterine fundus to the most sophisticated electronic intrauterine pressure monitoring system. The form of monitoring required depends largely on the clinical situation. The relationship between fetal oxygenation and uterine contractions has ensured the continued place of(More)
The electronic fetal monitor or cardiotocograph is an integral part of all modern labour wards. It records fetal heart and uterine contractions and charts this data as a cardiotocogram (CTG). The CTG is used to assess fetal well-being by the labour attendants and in some circumstances for research. A means to acquire and display the CTG by microcomputer as(More)
