Exposing the Effects of the “Invisible Hand” of the Neoliberal Agenda on Institutionalized Education and the Process of Sociocultural Reproduction

The neoliberal proposition that the “invisible hand” of the market is the most efficient and just mechanism for structuring economies, societies, and cultures has had a powerful impact on the nature and delivery of what have historically been considered as “public goods” in America, including social welfare services and public education. The mode of operation through which extensive and powerful networks of organizations dedicated to the prosecution of the neoliberal policy agenda and the ideological propositions and popular culture mythology that serve to support the conceptual frameworks that undergird them run counter to the realities of overarching social structures in America. In point of fact, these ideological and mythological tenets and images work to obscure these dispositive structural realities, many of which revolve around the operative dynamics of social capital networks and the ability of persons across a class structure to create and/or access such networks. Herein, we undertake an examination of how the resulting interplay of social structure, culture and individual agency lies at the heart of the process through which neoliberal propositions take on the aura of hegemony and become subject to sociocultural reproduction across generations.     

Thyroid hormone levels and psychological symptoms in sexually abused adolescent girls

OBJECTIVE: To explore the relationships between psychological symptoms and thyroid hormone levels in adolescent girls who had experienced the traumatic stress of sexual abuse. METHOD: The study design was cross-sectional/correlational. Subjects (N=22; age range=12-18 years) had their blood drawn, and they completed 2 psychological tests (depression and general distress/posttraumatic stress disorder [PTSD]). A pediatrician completed a sexual abuse questionnaire after reviewing law enforcement and Child Protective Services reports and conducting forensic interviews and medical examinations. RESULTS: Girls' average free T4, total T4, free T3, total T3, and TSH levels were within age-specific laboratory reference range limits, as were most individual concentrations. The strongest correlations (p<.05) were between free T3 and PTSD total score (-.50), PTSD-avoidance/numbing (-.49), and general distress (-.48); and between total T3 and depression (-.46), general distress (-.45), and PTSD-arousal (-.44). CONCLUSIONS: Our findings support one of the two contemporary models of the relationships between thyroid hormones (i.e., free and total T3) and psychological symptoms (i.e., depression, general distress, and PTSD)--one of "shutting down" (vs. "activation") in the face of trauma.     

Supplementing floundering text with adjunct displays

Three experiments compared the learning potential of text versus outline and matrix displays. In Experiments 1 and 2, college students read or heard a passage about fish and then studied the text, an outline, or a matrix. In Experiment 3, students heard a passage about wildcats, and then studied text, outline, or matrix displays. In all experiments, the text, outline, and matrix formats were informationally equivalent. However, the two-dimensional matrix appeared more computationally efficient than the linear organized text or outline because it (a) positioned related information about fish or wildcats in closer proximity so that local relations within a single category (such as size) were learned, and (b) organized information spatially so that global relations across categories (such as size and diet) were learned. The learning potential of text, outline, and matrix displays was also examined in combination with variations in thematic organization, amount of study time, and time of testing. The most important and consistent findings were that (a) outline and matrix displays produced greater relational learning than the text, and (b) matrix displays produced greater relational learning than outlines.     

On the cultural validity of science assessments

We propose the concept of cultural validity as a form of test validity in science assessment. The conceptual relevance of cultural validity is supported by evidence that culture and society shape an individual's mind and thinking. To attain cultural validity, the process of assessment development must consider how the sociocultural context in which students live influences the ways in which they make sense of science items and the ways in which they solve them. These sociocultural influences include the values, beliefs, experiences, communication patterns, teaching and learning styles, and epistemologies inherent in the students' cultural backgrounds, as well as the socioeconomic conditions prevailing in their cultural groups. We contend that current approaches to handling student diversity in assessment (e.g., adapting or translating tests, providing assessment accommodations, estimating test cultural bias) are limited and lack sociocultural perspective. We find that attaining cultural validity may conflict with current basic principles and assumptions in testing, such as item independence and standardization. We discuss the ways in which adopting cultural validity as a criterion for test validity makes it necessary to shift assessment paradigms and adopt new procedures for assessment development. © 2001 John Wiley & Sons, Inc.

Longitudinal Associations of Childhood Parenting and Adolescent Health: The Mediating Influence of Social Competence

The current study examined a process through which parenting during the primary school transition contributes to cardiovascular health in adolescence, a foundational period for adult health trajectories. Using path analyses, social competence was tested as a mediator between parental sensitivity and adolescent health among 884 families. Results indicated that mothers’ and fathers’ sensitivity was associated with increasing social competence from first grade (age 7) to sixth grade (age 12), which was associated with higher awakening cortisol in ninth grade (age 15) and decreasing blood pressure from sixth to ninth grade. Results suggest that social competence mediates associations between childhood parenting and adolescent cardiovascular risk, and may be protective to children's health over time.
