Experimental and Theoretical Predictors for Redox Potentials of Bispyridinylidene Electron Donors.

Bispyridinylidenes are neutral organic molecules capable of two-electron oxidation at a range of redox potentials that are widely tunable by choice of substituent, making them attractive as homogeneous organic reductants and active materials in redox flow batteries. In an effort to readily predict the redox potentials of this important class of compounds, we have developed correlations between the experimental redox potentials and both experimental and theoretical predictors. On the experimental side, we show that multinuclear NMR chemical shifts of related pyridinium ions correlate well with the redox potentials of bispyridinylidenes, with R and standard errors (S) reaching 0.

Longitudinal Examination of Which Married Young Women Use Contraception to Delay a First Pregnancy in Bihar and Uttar Pradesh, India.

Early marriage and childbearing put young women and their babies at risk of poor health and well-being. This study uses two rounds of longitudinal data from young women ages 15-19 in 2015-2016 and followed in 2018-2019 to determine factors associated with contraceptive use before a first pregnancy among young, married women in Bihar and Uttar Pradesh, India. Discrete time hazard models were used to analyze time to first use starting from the month of marriage.

The more, the better: influence of family planning discussions during the maternal, newborn and child health continuum of care on postpartum contraceptive uptake and method type among young women in Ethiopia.

This study examines the association between family planning (FP) discussions with health professionals during contact points on the maternal, newborn and child health continuum of care and timing of modern contraceptive uptake and method type in the one-year following childbirth in six regions of Ethiopia among adolescent girls and young women (AGYW). : This paper uses panel data of women aged 15-24 who were interviewed during pregnancy and the postpartum period between 2019-2021 as part of the PMA Ethiopia survey (n=652).  : Despite the majority of pregnant and postpartum AGYW attending antenatal care (ANC), giving birth in a health facility, and attending vaccination visits, one-third or less of those who received the service reported discussion of FP at any of these visits.

"So let me give you money, you give me what I want": decision-making priorities around contraceptive method and source choice among young women in Kenya.

Background: Many factors influence young women's choice of contraceptive methods and where to source them, yet less is known about whether one of these choices (method or source) is prioritized and the relationship between these choices. This study qualitatively explored decision-making around contraceptive method and source choice among young women in Kenya.

Methods: In August-September 2019, 30 in-depth interviews were conducted with women ages 18-24 who had used two or more contraceptive methods and resided in three counties: Nairobi, Mombasa or Migori.

Community perspectives on family planning service quality among users and non-users: a qualitative study from two cities in Burkina Faso.

Background: Most studies that focus on quality of family planning (FP) services collect data from facilities. These studies miss the perspectives of quality from women who do not visit a facility and for whom perceived quality may be a barrier to service utilization.

Methods: This qualitative study from two cities in Burkina Faso examines perceived quality of FP services from women who were recruited at the community level to avoid potential biases based on recruiting women at facilities.
