Random Coefficient Models for Time-Series-Cross-Section Data: Monte Carlo Experiments

Jonathan N. Katz Division of the Humanities and Social Sciences, California Institute of Technology, Pasadena, CA 91125 e-mail: jkatz{at}caltech.edu e-mail: nathaniel.beck{at}nyu.edu (corresponding author) This article considers random coefficient models (RCMs) fortime-series–cross-section data. These models allow forunit to unit variation in the model parameters. The heart ofthe article compares the finite sample properties of the fullypooled estimator, the unit by unit (unpooled) estimator, andthe (maximum likelihood) RCM estimator. The maximum likelihoodestimator RCM performs well, even where the data were generatedso that the RCM would be problematic. In an appendix, we showthat the most common feasible generalized least squares estimatorof the RCM models is always inferior to the maximum likelihoodestimator, and in smaller samples dramatically so.

Violence against women in video games: a prequel or sequel to rape myth acceptance?

Current research suggests a link between negative attitudes toward women and violence against women, and it also suggests that media may condition such negative attitudes. When considering the tremendous and continued growth of video game sales, and the resulting proliferation of sexual objectification and violence against women in some video games, it is lamentable that there is a dearth of research exploring the effect of such imagery on attitudes toward women. This study is the first study to use actual video game playing and control for causal order, when exploring the effect of sexual exploitation and violence against women in video games on attitudes toward women. By employing a Solomon Four-Group experimental research design, this exploratory study found that a video game depicting sexual objectification of women and violence against women resulted in statistically significant increased rape myths acceptance (rape-supportive attitudes) for male study participants but not for female participants.     

Shuttle and Online Mediation: A Review of Available Research and Implications for Separating Couples Reporting Intimate Partner Violence or Abuse

Whether family law cases with a history of severe intimate partner violence and/or abuse (IPV/A cases) should have the option of settling family‐related issues using mediation is the subject of significant debate. Recommendations for potentially safer ways to mediate IPV/A cases have been developed, including shuttle and online mediation. Given the current lack of research on these forms of mediation with IPV/A cases, we review the research on shuttle and online mediation in other contexts and theorize how the findings might apply to IPV/A cases. We argue that, although online and shuttle mediation may benefit IPV/A cases, aspects of these procedures require special considerations.     

¿Qué es racismo?: awareness of racism and discrimination in Ecuador

In the national consciousness, Ecuador is a mestizo nation. However, it is also an ethnically diverse nation with sizable minorities of indigenous and Afrodescended peoples. In national surveys, there is also a considerable minority who self-identify as blanco (white). Although there is strong evidence of continuing discrimination and prejudice toward both indigenous and Afro-descended peoples, there is little public discussion or political action addressing such issues. The emergence of a powerful and resilient indigenous movement in the late 1980s gained international interest and acclaim in the 1990s, in part because of the peaceful mobilization efforts and effective bargaining tactics of the movement. However, indigenous leaders usually have not engaged in a discourse of racismo and/or discriminación. There has been much less social movement solidarity and activism among Afro-Ecuadorians, but their leaders commonly employ a discourse of racismo and discriminación. In August and September 2004, a survey of more than eight thousand adult Ecuadorians was conducted in regard to racism and related topics. In this research, we use several measures from this survey that focus on awareness of and sensitivity to issues of racism, prejudice, and discrimination. Self-identification of respondents enables us to contrast the responses of whites, mestizos, Indians, and Afro-Ecuadorians to the measures. Other independent variables of interest are level of education, the region in which the respondent resides, and whether the respondent lives in an urban or rural area. Regression results show differences among the ethnic groups in levels of awareness of racism, but more powerful predictors are level of education and rural residence.     

Comorbid Pain and PTSD: Integrating Research and Practice with MVC Survivors

Following a serious motor vehicle crash (MVC), an individual may develop posttraumatic stress disorder (PTSD) as well as chronic pain. To date, little work has been done that can empirically guide practitioners with an evidence-based approach for psychological interventions in this population. Issues related to the changing definitions of PTSD and ways in which we conceptualize pain-related concerns are discussed, with implications for understanding the complex interrelationships between these two conditions. Theoretical and practical understanding of the common processes which contribute to the comorbidity of PTSD and pain is shared, along with information regarding assessment and applications from the limited treatment literature. Suggestions drawn from clinical practice are offered regarding assessment and treatment for individuals diagnosed with PTSD and pain in a MVC population.     

Considering Destructive Interparental Conflict and Intimate Partner Abuse: Is there a Difference?

Building on existing evidence that destructive interparental conflict and intimate partner abuse (IPA) share research methodology and predict the same adjustment difficulties across numerous areas of child development, this article brings awareness to differences in terminology across disciplines and the impact these nuanced differences may have on families. We begin by identifying two main streams of scholarships followed by a discussion of research methodology similarities and differences. Important implications of differences in naming conventions for practitioners, legal and academic scholars, and victims are then discussed. Finally, we encourage professionals from both scholarships to consider referencing the other's terminology and using comprehensive assessments to better promote the well‐being of families.
