Argumentation and Explanation in Conceptual Change: Indications From Protocol Analyses of Peer-to-Peer Dialog

In this paper we attempt to identify which peer collaboration characteristics may be accountable for conceptual change through interaction. We focus on different socio-cognitive aspects of the peer dialog and relate these with learning gains on the dyadic as well as the individual level. The scientific topic that was used for this study concerns natural selection, a topic for which students' intuitive conceptions have been shown to be particularly robust. Learning tasks were designed according to the socio-cognitive conflict instructional paradigm. After receiving a short instructional intervention on natural selection, paired students were asked to collaboratively construct explanations for certain evolutionary phenomena while engaging in dialectical argumentation. Two quantitative coding schemes were developed, each with a different granularity. The first assessed discrete dialog moves that pertained to dialectical argumentation and to consensual explanation development. The second scheme characterized the dialog as a whole on a number of socio-cognitive dimensions. Results from analyses on the dyadic as well as the individual level revealed that the engagement in dialectical argumentation predicted conceptual learning gains, whereas consensual explanation development did not. These findings open up new venues for research on the mechanisms of learning in and from peer collaboration.     

Identity theft and consumers' reaction to preventive technological innovations

The use of identification technology by commercial entities has broad and, for some consumers, disturbing social implications. This two-phase study was done to specify consumers' concerns regarding various identification technologies which may be encountered in retail environments. From the qualitative findings, a 26-item survey was constructed to quantify identified areas of concern with 303 survey participants (147 women and 156 men), whose mean age category was 30 to 39 years. Using exploratory factor analysis (principal components with varimax rotation), five dimensions of consumers' concern emerged: privacy, ethics, health, humanity, and complexity.     

African American Children’s Depressive Symptoms: The Prospective Effects of Neighborhood Disorder, Stressful Life Events, and Parenting

The prospective effects of observed neighborhood disorder, stressful life events, and parents’ engagement in inductive reasoning on adolescents’ depressive symptoms were examined using data collected from 777 African American families. Multilevel analyses revealed that stressful life events experienced at age 11 predicted depressive symptoms at age 13. Furthermore, a significant interaction between neighborhood disorder and parents’ engagement in inductive reasoning was found, indicating that parental use of inductive reasoning was a protective factor for depressive symptoms particularly for youths living in highly disordered neighborhoods. The importance of examining correlates of depressive symptoms from a contextual framework, focusing on individuals, families, and neighborhood contexts, is emphasized.     

Intellectual property and biotechnology: the European debate

The European patent system allows for the introduction of moral issues into decisions about the granting of patents. This feature has greatly impacted European debates about the patenting of biotechnology. This essay explores the European experience, in both the European Union and the European Patent Organization. It argues that there has been great confusion surrounding these issues primarily because the Europeans have not developed a general theory about when exclusion from patentability is the best social mechanism for dealing with morally offensive technologies.     

Born and raised to be a fraudster

Although a great deal of research has focussed on and continues to focus on fraud prevention and detection, there is still no reliable way to predict who will become a white‐collar criminal/fraudster. Significant benefits would result if and when this can be done. This paper recognizes that there are many common characteristics that exist among fraudsters and investigates whether fraud can be predicted based on the psychological, sociological, and environmental state of children throughout their upbringing. Research shows that children with a negative childhood develop negative habits, emotions, and mentalities, including disorders that can linger well into their adult lives. These negative characteristics can ruin relationships and possibly even influence an individual to commit fraud. This paper provides initial evidence regarding the potential significance of some childhood characteristics that may contribute to the likelihood that someone will become a white‐collar criminal. Given that no other similar research exists, this paper may help guide future researchers who are also attempting to solve this complex problem.     

The Costs of Silencing the Self and Divided Self in the Context of Physical Abuse,Racial/Ethnic Identity,and Medication Adherence in Women Living with HIV

Racial/ethnic minority status and physical abuse history are risk factors for higher mortality rates and lower adherence to antiretroviral therapy (ART) in women living with HIV (WLWH) in the United States. The current study tested the hypotheses that minority status and physical abuse history might lead women to silence the self (minimize and hide thoughts and feelings in order to avoid relational conflict, loss, and/or abuse) as measured by the Silencing the Self Scale (STSS), and that STSS might mediate and moderate relationships of physical abuse and racial/ethnic minority status with ART adherence. Divided Self (DS; acting in ways inconsistent with inner thoughts and feelings), an STSS subscale, was targeted for study along with the total STSS score. Participants were 513 women from the U.S. Women’s Interagency HIV Study (M_age?=?46; 387, 75%, Black; 66, 13%, Hispanic; 60, 12%, White). Multiple logistic regressions indicated that across all racial/ethnic groups, physical abuse history related to higher DS and lower adherence. DS significantly mediated relationships between abuse and adherence. Compared to White women, Black women demonstrated worse ART adherence, but had lower total STSS. Racial/ethnic minority women and women with a physical abuse history who had higher DS had lower adherence than other groups. Results indicate that being a racial/ethnic minority or having a history of physical abuse may increase vulnerability to the deleterious effects of DS on ART adherence, findings that can help inform interventions to decrease health disparities in WLWH.
