In this paper, a novel way of deriving proportionate adaptive filters is proposed based on diversity measure minimization using the iterative reweighting techniques well-known in the sparse signal recovery (SSR) area. The resulting least mean square (LMS)-type and normalized LMS (NLMS)-type sparse adaptive filtering algorithms can incorporate various diversity measures that have proved effective in SSR. Furthermore, by setting the regularization coefficient of the diversity measure term to zero in the resulting algorithms, Sparsity promoting LMS (SLMS) and Sparsity promoting NLMS (SNLMS) are introduced, which exploit but do not strictly enforce the sparsity of the system response if it already exists. Moreover, unlike most existing proportionate algorithms that design the step-size control factors based on heuristics, our SSR-based framework leads to designing the factors in a more systematic way. Simulation results are presented to demonstrate the convergence behavior of the derived algorithms for systems with different sparsity levels.Breastfeeding is something that many new mothers aspire to do, but also something that many struggle with in the days following birth. Nursing support in the hospital can make a huge difference in the success of this endeavor for many patients. It is important for nurse educators that work with the obstetric population, and the nurses that care for them, to understand what drives nurses to be supportive of patients who have recently given birth in their breastfeeding efforts. This will allow for appropriate interventions to be implemented to increase the level of support. This study seeks to determine if a relationship exists between nurses' level of education and specialty certification, and their intent to provide support to new mothers in their efforts to breastfeed their babies.Primigravid women, at some point, feel the need to gain education about childbirth. Our objective was to identify where primigravid millennial moms are seeking their childbirth education. This study, a quantitative nonexperimental survey research, was designed within the context of developmental transition theory. Childbearing women were recruited, considering the phenomenon to be studied. This purposive sample of 100 participants included primigravid millennial mothers (born between 1978 and 1994), status post vaginal birth, or emergent cesarean surgery, on a 455-bed, acute care facility. All participants were able to speak, understand, and read English or Spanish fluently. The author used a self-report survey to collect data from the participants. Primigravid women responded to a series of questions posed by the investigator. Considering the participants' variety of reading levels and their ability to communicate in writing, special attention was given to the simplicity and clarity of the questions on the survey. The responses provided by the participants suggested the need to enhance current childbirth education into culturally friendly and evidence-based technological information. Websites, apps, and social media are important information channels to reach and disseminate valuable childbirth education for millennial primigravid women. However, these channels are not currently being used to their full potential, considering the amount of information available and lack of guidance and clarity to disseminate trustworthy health-care information. By understanding millennial moms' choices, we gain the opportunity to deliver better education and support to Internet savvy women who are seeking online health-care information.Recognized risk factors influencing the birth experience and subsequent poor mental health are not addressed among childbearing adolescents, especially minority teens. Our study purpose was to compare birth experiences of three adolescent groups by prevalence and influence of selected risk factors as moderated by racial/ethnic background. Using a birth rating scale and the Impact of Event Scale, birth perception and stress were examined among an equal number of Black, White, and Hispanic adolescents. Surveys completed at 72 hours postpartum showed Black adolescents most at risk for a negative birth experience.

Risk factors occur before and after birth; therefore, childbirth educators can promote a positive birth experience via perinatal assessments and interventions.<br />This article is a meta-analysis of studies examining the influence of doula support on birth outcomes among African American women with disabilities. While an estimated 11% of women in their childbearing years are impacted by some type of disability, mothers with disabilities are faced with risks during pregnancy. When risks in addition to maternal disability are present, mothers may encounter extra barriers that impede receipt of effective care.<br />A meta-analysis of studies revealed women with disabilities are at risk for poor birth outcomes. Specifically, women of color living in poverty-stricken areas are at a greater risk for adverse birth outcomes.<br />As a result of adverse experiences related to birth, mothers may experience levels of traumatic stress. To advocate for better pregnancy and birth outcomes, the intervention of doula support is emphasized.<br />There is a widely recognized need to promote better pregnancy outcomes among African American women to address disproportionate birth outcomes. Strategies to enhance doula support among African American women with disabilities are offered. Implications include future research surrounding the development of a training program for doulas specific to disability, trauma-informed care, and maternal mental health.<br />There is a widely recognized need to promote better pregnancy outcomes among African American women to address disproportionate birth outcomes.
