The Spockian Mother: Images of the “Good” Mother in Dr. Spock’s The Common Sense Book of Baby and Child Care, 1946–1992

Dr. Spock’s, The Common Sense Book of Baby and Child Care, one of the best-selling self-help texts of all-time, “second only to the Bible in popularity” (Meakin & Tattersall, 2004) was one of the most influential childcare books in American culture. The author has been both heralded and disparaged as instrumental in the shaping of untold generations. In the present study, we address the rhetorical construction of the Spockian Mother as she is developed during Spock’s tenure from 1946–1992. We employ a feminist rhetorical perspective to examine the progression of Spock’s texts in order to understand how patriarchal images of motherhood are constructed and maintained through Spock’s lifetime and the first 46 years of its publication. We argue that Spock both reinforced and challenged the institution of motherhood; he challenged institutionalized motherhood by encouraging mothers to “trust themselves” while simultaneously conforming to a patriarchal model of motherhood which is at odds with empowered mothering.     

Numerical Estimation in Deaf and Hearing Adults

Deaf students often lag behind hearing peers in numerical and mathematical abilities. Studies of hearing children with mathematical difficulties highlight the importance of estimation skills as the foundation for formal mathematical abilities, but research with adults is limited. Deaf and hearing college students were assessed on the Number-to-Position task as a measure of estimation, and completed standardised assessments of arithmetical and mathematical reasoning. Deaf students performed significantly more poorly on all measures, including making less accurate number-line estimates. For deaf students, there was also a strong relationship showing that those more accurate in making number-line estimates achieved higher scores on the math achievement tests. No such relationship was apparent for hearing students. Further insights into the estimation abilities of deaf individuals should be made, including tasks that require symbolic and non-symbolic estimation and which address the quality of estimation strategies being used.     

Disambiguating the components of emotion regulation

Affective neuroscience and cognitive science approaches are useful for understanding the components of emotion regulation; several examples from current research are provided. Individual differences in emotion regulation and a focus on the context of emotion experience and expression provide additional tools to study emotion regulation, and its development, from a biobehavioral perspective.     

Report to the President on the Use of Technology to Strengthen K–12 Education in the United States: Findings Related to Research and Evaluation

The Panel on Educational Technology was organized in April 1995 under the auspices of the President's Committee of Advisers on Science and Technology (PCAST) to provide advice to the President on matters related to the application of information technologies to K–12 education in the United States. Its findings and recommendations were set forth in March 1997 in the Report to the President on the Use of Technology to Strengthen K–12 Education in the United States. This report was based on a review of the research literature and on written submissions and oral briefings from a number of academic and industrial researchers, practicing educators, software developers, governmental agencies, and professional and industry organizations involved in various ways with the application of technology to education. Its most important finding is that a large-scale program of rigorous, systematic research on education in general and educational technology in particular will ultimately prove necessary to ensure both the efficacy and cost-effectiveness of technology use within our nation's K–12 schools. Finding that less than 0.1 percent of our nation's expenditures for elementary and secondary education are currently invested to determine which educational techniques actually work, and to find ways to improve them—an extremely low level relative to comparable ratios within the private sector—the Panel recommended that this figure be increased over a period of several years to at least 0.5 percent, and sustained at that level on an ongoing basis. Further, because no one state, municipality, or private firm could hope to capture more than a small fraction of the benefits associated with a significant advance in our understanding of how best to educate K–12 students, the Panel concluded that such funding will have to be provided largely at the federal level in order to avoid a systematic underinvestment (attributable to a classical form of economic externality) relative to the level that would be optimal for the nation as a whole. This paper originally appeared as Section 8 of the report.     

Black women’s bodies,ideology, and the public curriculum of the pro- and anti-choice movements in the US

This paper explores how opposite sides of the abortion debate employ a discourse of endangerment to mobilise political support for their ideologies about black women’s bodies. I examine the role of black women within that rhetorical strategy through various rhetorical artefacts. To analyse these artefacts, I employ the theoretical framework of ideological or ideographic criticism. This framework helps us see how the artefacts used by both pro and anti-choice movements ‘condition’ the audience not merely to adopt a set of ‘beliefs and behavior, but a vocabulary of concepts that function as guides, warrants, reasons, or excuses for behavior and belief’. Though the two sides of the abortion debate differ in their overt political views, they turn out to share an implicit ideology about black women. This ideology prevents the voices of black women from being heard and valued in a debate that is nonetheless focused on black women’s bodies.     

Prenatal testosterone,visual-spatial memory,and numerical skills in young children

Lateralization of the brain is strongly influenced by prenatal androgens, with differential exposure thought to account for cognitive sex differences. This study investigated sex and individual differences and relationships between 2D:4D (the ratio of the 2nd to 4th digit [digit ratio] as a proxy indicator of prenatal testosterone exposure), visual-spatial memory, and numerical skills in 5-year-old children. No sex differences were found in any of the numerical or visual-spatial tasks. Visual-spatial memory was positively correlated with arithmetic score. Girls with a lower (more masculinised) 2D:4D had better number sense and visual-spatial skills, whilst boys with lower 2D:4D had better arithmetic skills. This suggests that prenatal testosterone exposure may have differential effects on the visual-spatial and numerical skills of girls and boys.     

Oxford House: deaf-affirmative support for substance abuse recovery

Deaf individuals seeking substance abuse recovery are less likely to have access to treatment and aftercare services because of a lack of culturally and linguistically specific programs and insufficient information about existing services. Previous research indicates that Oxford House, a network of resident-run recovery homes, serves a diverse group of individuals in recovery. However, research has not addressed the experiences of Deaf Oxford House residents. The present study found no significant differences between Deaf and hearing men living in Oxford House in terms of sense of community and abstinence self-efficacy. However, while most of the hearing participants were employed, none of the Deaf Oxford House members were. The study's findings indicate that Oxford House may be a promising Deaf-affirmative alternative for individuals seeking recovery from substance abuse. However, since Oxford Houses are self-supporting, Oxford Houses designed for the Deaf community may face unique economic challenges.     

Hope as a Mediator of Loneliness and Academic Self‐efficacy Among Students With and Without Learning Disabilities during the Transition to College

The transition to college often occasions excitement as well as elevated stress for students. The latter may be especially the case for those with learning disabilities (LD), who can encounter problems both socially and academically. This study follows students both with and without LD during the first month of college to explore the relationships between LD status and two outcomes: loneliness/social distress and academic self‐efficacy. In particular, we hypothesized that hope and optimism would mediate the relationship between LD status and these outcomes. The sample consisted of 344 first‐year undergraduates at the beginning of the academic year (Time‐1) and a month later (Time‐2). Results showed that LD status predicted Time‐2 levels of academic self‐efficacy and loneliness only indirectly, demonstrating that relationships between LD and loneliness as well as between LD and academic self‐efficacy are mediated by hope.     

Values education: The Power2Achieve approach for building sustainability and enduring impact

Schools today struggle to prepare students for the moral and performance character challenges they will face in the 21st Century. Whether it is bolstering academic performance, reducing dropout, or improving integrity and safety, developing the character and culture of excellence and ethics is a critical need of schools—and yet they must do so with limited time and money amid a sea of competing priorities and mandates, and without the aid of required curricula, training and coaching. In this article, we describe the Power2Achieve Program, a student-centered, teacher-delivered program for developing the character and culture needed for success in school, work and beyond. We lay out the key theoretical and practical features of the program, describe how it aligns with and enhances other current school improvement pedagogies, and present our research approach for continuous improvement and assessment of impact.
