The 4-vessel Sampling Approach to Integrative Studies of Human Placental Physiology In Vivo

Abstract:
A field study focusing on men's experiences of first-time expectant fatherhood, including intensive interviews with 20 expectant couples, short field interviews with 80 additional fathers, participant observation in prenatal classes and clinics, and content analysis of popular literature was conducted for the purpose of description and generation of substantive theory. Interview and field data were analyzed using constant comparative analytic technique for qualitative data. Evidence suggest a characteristic pattern of development of subjective emotional involvement in pregnancy among first-time expectant fathers. This pattern consists of three phases: an announcement phase, a moratorium and a focusing phase. The length of the second phase appears to be related to the man's perception of his own readiness for pregnancy. The father's speed of progression though these phases may affect later adjustment to fatherhood. Further testing and validation of these findings is indicated.

Authoritarian Parenting
This style is strict and controlling, with little room for open dialogue. Authoritarian parents demand obedience and often enforce rules with minimal warmth. Children raised this way may lack social skills and initiative, usually comparing themselves to others unfavorably.
