Low-Income Women Describe Fertility-Related Expectations: Descriptive Norms, Injunctive Norms, and Behavior

Social norms surrounding sexuality, pregnancy, and childbearing may help guide women's health-related behaviors. In this study, we explore low-income women's perceptions of fertility-related norms by allowing women to describe their experiences with normative expectations. Semistructured interviews (n = 30) suggested that women in low-income subject positions articulate descriptive norms that generally correspond with mainstream descriptive norms, identify two major sources of injunctive norms concerning fertility and sexuality— authoritative and peer-oriented—and often align their behaviors according to subgroup expectations communicated in the form of peer-oriented injunctive norms. We discuss these results in light of the extant literature on social norms

Narrative Sense-making and Time Lapse: Interviews with Low-income Women about Sex-Education

Secondary-school students in the United States score notoriously low on tests of their reproductive and sexual knowledge despite attempts by educators and legislators to provide them with informative sex-education courses. In this paper, we build from narrative theory to explore how low-income women perceived their formal sex-education experiences and how they connected those experiences to their sexual-health knowledge, beliefs, and behaviors. Drawing from interviews with 30 low-income women, we identify and develop a typology of sex-education narratives: narratives of regret, narratives of satisfaction, and narratives of uncertainty. We also investigate existing theoretical claims that lapses in time between lived events and the narration of those events connect to sensemaking efforts. We find that younger women in the sample were more likely to tell narratives of uncertainty than were older women. These results have implications for the study of narrative theory, sexual-health communication, and the discourse of public sex education

Fertility-Related Perceptions and Behaviors among Low-Income Women: Injunctive Norms, Sanctions, and the Assumption of Choice

In this article we explore elements of the theory of normative social behavior (TNSB) through interviews with low-income women (N = 30) in a Midwestern U.S. state about their experiences with and perceptions of fertility-related norms. Using grounded theory and matrix analysis as analytical lenses, we found that individuals sometimes learn of injunctive norms and social sanctions separately, might be more likely to comply with a norm if they learn about norms and sanctions in concert, and might be more likely to engage in norm compliance if they learn about two different types of sanctions, short- and long-term, along with the injunctive norm. We also found that a number of important barriers can limit one’s ability to choose to comply with a norm. In conclusion, we discuss implications for continued theorizing of the TNSB in light of the experiences of traditionally marginalized populations

Theorizing the Transcendent Persona: Amelia Earhart’s Vision in The Fun of It

In this article, we define and theorize the ‘‘transcendent persona,’’ a discursive strategy in which a rhetor draws from a boundary-breaking accomplishment and utilizes the symbolic capital of that feat to persuasively delineate unconventional ways of communicating and behaving in society. Aviator Amelia Earhart’s autobiography The Fun of It (1932) functions as an instructive representative anecdote of this concept and demonstrates that the transcendent persona’s persuasive force hinges on one’s ability to balance distance from audiences with similarities to them. Striking such a balance creates a platform for rhetors to promote transformative visions of society. Earhart utilized the transcendent persona to illustrate an alternative vocabulary of what contemporary theorists might call feminine gender performativity. The article concludes by exploring the implications of the transcendent persona as an enduring, rhetorical resource for communicators, as well as for scholars of persuasion and social change, religious communication, and communication history

Child Psychosocial Adjustment and Parenting in Families Affected by Maternal HIV/AIDS

Child adjustment and parenting were examined in 23 9-through 16-year-old youth from families affected by maternal HIV infection and 20 same-age peers whose mothers were not infected. Children whose mothers were seropositive reported significantly more externalizing problems. Infected mothers reported less age-appropriate supervision/monitoring relative to non-infected mothers. Better mother-child relationship quality and less impairment in parental supervision/monitoring of age-appropriate youth behaviors were associated with fewer externalizing difficulties among the HIV-positive group only. Similarly, only among HIV-infected mothers was refraining from engaging in inconsistent disciplinary tactics associated with lower reports of internalizing and externalizing problems. These data highlight the promise of programs targeting parenting skills to prevent or ameliorate child difficulties

Clevidipine for severe hypertension in patients with renal dysfunction: A VELOCITY trial analysis

Introduction. Acute and severe hypertension is common, especially in patients with renal dysfunction (RD). Clevidipine is a rapidly acting (t½∼1 min) intravenous (IV) dihydropyridine calcium-channel blocker metabolized by blood and tissue esterases and may be useful in patients with RD. The purpose of this analysis was to assess the safety and efficacy of clevidipine in patients with RD. Methods. VELOCITY, a multicenter open-label study of severe hypertension, enrolled 126 patients with persistent systolic blood pressure (SBP) >180 mmHg. Investigators pre-specified a SBP initial target range (ITR) for each patient to be achieved within 30 min. Blood pressure monitoring was by cuff. Clevidipine was infused via peripheral IV at 2 mg/h for at least 3 min, then doubled every 3 min as needed to a maximum of 32 mg/h (non-weightbased treat-to-target protocol). Per protocol, clevidipine was continued for at least 18 h (96 h maximum). RD was diagnosed and reported as an end-organ injury by the investigator and was defined as requiring dialysis or an initial creatinine >2.0 mg/dl. Primary endpoints were the percentage of patients within the ITR by 30 min and the percentage below the ITR after 3 min of clevidipine infusion. Results. Of the 24 patients with moderate to severe RD, most (13/24) were dialysis dependent. Forty-six percent were male, with mean age 51 >14 years; 63% were black and 96% had a hypertension history. Median time to achieve the ITR was 8.5 min. Almost 90% of patients reached the ITR in 30 min without evidence of overshoot and were maintained on clevidipine through 18 h. Most patients (88%) transitioned to oral antihypertensive therapy within 6 h of clevidipine termination. Conclusions. This report is the first demonstrating that clevidipine is safe and effective in RD complicated by severe hypertension. Prolonged infusion maintained blood pressure within a target range and allowed successful transition to oral therapy

Haptoglobin Phenotype, Preeclampsia Risk and the Efficacy of Vitamin C and E Supplementation to Prevent Preeclampsia in a Racially Diverse Population

Haptoglobin's (Hp) antioxidant and pro-angiogenic properties differ between the 1-1, 2-1, and 2-2 phenotypes. Hp phenotype affects cardiovascular disease risk and treatment response to antioxidant vitamins in some non-pregnant populations. We previously demonstrated that preeclampsia risk was doubled in white Hp 2-1 women, compared to Hp 1-1 women. Our objectives were to determine whether we could reproduce this finding in a larger cohort, and to determine whether Hp phenotype influences lack of efficacy of antioxidant vitamins in preventing preeclampsia and serious complications of pregnancy-associated hypertension (PAH). This is a secondary analysis of a randomized controlled trial in which 10,154 low-risk women received daily vitamin C and E, or placebo, from 9-16 weeks gestation until delivery. Hp phenotype was determined in the study prediction cohort (n = 2,393) and a case-control cohort (703 cases, 1,406 controls). The primary outcome was severe PAH, or mild or severe PAH with elevated liver enzymes, elevated serum creatinine, thrombocytopenia, eclampsia, fetal growth restriction, medically indicated preterm birth or perinatal death. Preeclampsia was a secondary outcome. Odds ratios were estimated by logistic regression. Sampling weights were used to reduce bias from an overrepresentation of women with preeclampsia or the primary outcome. There was no relationship between Hp phenotype and the primary outcome or preeclampsia in Hispanic, white/other or black women. Vitamin supplementation did not reduce the risk of the primary outcome or preeclampsia in women of any phenotype. Supplementation increased preeclampsia risk (odds ratio 3.30; 95% confidence interval 1.61-6.82, p<0.01) in Hispanic Hp 2-2 women. Hp phenotype does not influence preeclampsia risk, or identify a subset of women who may benefit from vitamin C and E supplementation to prevent preeclampsia

Reconciling emergences: An information-theoretic approach to identify causal emergence in multivariate data.

The broad concept of emergence is instrumental in various of the most challenging open scientific questions-yet, few quantitative theories of what constitutes emergent phenomena have been proposed. This article introduces a formal theory of causal emergence in multivariate systems, which studies the relationship between the dynamics of parts of a system and macroscopic features of interest. Our theory provides a quantitative definition of downward causation, and introduces a complementary modality of emergent behaviour-which we refer to as causal decoupling. Moreover, the theory allows practical criteria that can be efficiently calculated in large systems, making our framework applicable in a range of scenarios of practical interest. We illustrate our findings in a number of case studies, including Conway's Game of Life, Reynolds' flocking model, and neural activity as measured by electrocorticography
