What is the canonical theory of assimilation?

Throughout the past century, assimilation has been the hegemonic theory of ethnic group relations in sociology, and Robert E. Park is generally considered to be the key figure associated with the articulation of assimilation's canonical formulation. Based on a careful reading of Park's main essays on assimilation, this article argues that those who associate his position with the melting pot (with its assumption of the eradication of ethnic traits and ties), the race-relations cycle, or a straight-line process of incorporation misconstrue his views. This article is in part corrective and in part revisionist insofar as it is intended to indicate aspects of Park's theory that have particular relevance to current sociological efforts to understand the implications of assimilation in multiethnic liberal democracies.     

Emotion Dysregulation Mediates the Relationship Between Child Maltreatment and Non-Suicidal Self-Injury

One risk factor for non-suicidal self-injury (NSSI) in adolescents is exposure to traumatic experiences, particularly child maltreatment. However, the mechanisms through which childhood maltreatment predicts NSSI are largely unknown. Emotion dysregulation (ED) is likely an important mechanism in this relationship. Therefore, this study examined the relationship between childhood maltreatment, ED, and NSSI in a sample of adolescent inpatients (n = 53). Results demonstrated that child physical and emotional maltreatment, but not child sexual abuse, was significantly associated with NSSI frequency. More specifically, ED mediated the relationship between child physical and emotional maltreatment and NSSI frequency. Findings support the importance of ED as a mediating factor in the relationship between childhood maltreatment and NSSI behaviors and highlight the need for teaching emotion regulation skills to youth affected by trauma.     

Differential Effects of Two Spelling Procedures on Acquisition,Maintenance and Adaption to Reading

An alternating treatments design was used to assess the effects of a constant time delay (CTD) procedure and a cover-copy-compare (CCC) procedure on three students’ acquisition, subsequent maintenance, and adaptation (i.e., application) of acquired spelling words to reading passages. Students were randomly presented two trials of word lists from their respective curriculum under each condition once daily. Results suggest that both procedures were effective for helping students efficiently acquire spelling words, but the CCC condition resulted in more words learned for all participants, although less pronounced when instructional time was considered. However, the CTD procedure resulted in substantially higher levels of maintenance for Jeremy and Leon, with no significant difference between the two procedures for the Anthony. Adaptation of acquired spelling words to reading was about equal under both conditions for Anthony and Leon, while Jeremy showed higher levels of performance in the CTD procedure. Discussion focuses on discrepant results, matching instructional procedures to specific learning concerns, and directions for future research.
