Values,Communication Behavior,and Political Participation

This article examines how communication patterns mediate the influences of values on political participation. We find that the positive effects of postmaterial values on participation are mediated through reading public affairs content in newspapers. In contrast, materialist values negatively affect participation through watching television entertainment. Interpersonal discussion in which disagreement occurs mediates both the positive effect of reading public affairs and the negative effect of materialism on political participation. We also provide what may be a better explanation of the influence of communication patterns on political participation by going beyond acquisition of factual political knowledge. We show that individuals' efforts to think about news and search for additional information and perspectives modify what people "get from" media. Reflecting about news and integrating information from various sources promote better understanding of the political world and may provide a stronger cognitive base for political participation than factual political knowledge.     

A Perspective on Errors,Bias, and Interpretation in the Forensic Sciences and Direction for Continuing Advancement*

Abstract: The forensic sciences are under review more so than ever before. Such review is necessary and healthy and should be a continuous process. It identifies areas for improvement in quality practices and services. The issues surrounding error, i.e., measurement error, human error, contextual bias, and confirmatory bias, and interpretation are discussed. Infrastructure is already in place to support reliability. However, more definition and clarity of terms and interpretation would facilitate communication and understanding. Material improvement across the disciplines should be sought through national programs in education and training, focused on science, the scientific method, statistics, and ethics. To provide direction for advancing the forensic sciences a list of recommendations ranging from further documentation to new research and validation to education and to accreditation is provided for consideration. The list is a starting point for discussion that could foster further thought and input in developing an overarching strategic plan for enhancing the forensic sciences.     

The individuality of rubber stamps

Rubber stamps may be individualized through any of the steps in the manufacturing process even back-tracking to imperfections in the metal type faces. More commonly, individuality occurs from use, misuse, wear and even age of the stamp. Steps in the manufacturing process and causes of defects leading to identification of a rubber stamp are discussed.     

Reexamining Adolescent Suicidal Ideation: A Developmental Perspective Applied to a Diverse Population

The purpose of this study was to test the hypothesis that suicidal ideation is a common experience in a general population of African American, Hispanic, and White urban high school students residing in low-income neighborhoods. Based upon a developmental framework, it was hypothesized that once attitudes toward suicide were controlled, ideation would not vary significantly by ethnicity, gender, or psychosocial variables usually associated with ideation. The multivariate analysis revealed that ideation did not vary by ethnicity however, females, substance users, and those with greater tolerance toward suicide, higher family coping, and lower self-esteem were more likely to report ideation. A series of ideator profiles, calculated from the probability estimates, showed that an increase in tolerance substantially raises the likelihood of ideation. The results taken together raise the question of whether it is time to reconceptualize the relationship between ideation and normal adolescent development.     

Comparison of ages of epiphyseal union in North American and Bosnian skeletal material

The accurate determination of age at death is a critical component in the analysis of human skeletal remains. Population specific techniques are often used without due consideration of the provenance of the material being studied. This communication considers the ages at which epiphyseal union occur in young Bosnian males and compares those findings to data published by McKern and Stewart on young North American soldiers killed during the Korean War. Of the ten epiphyses considered in this study, all elements were observed to be at least two years in advance in the Bosnian sample compared to the American sample. This article demonstrates that whilst standards based on an American sample produce broadly applicable age ranges for use on forensic work in the Balkans, the age ranges generated produce an upper age limit that is often two or more years older than the chronological age. Therefore, it is desirable, that wherever possible, appropriate standards should be devised for more accurate aging reflecting population specific profiles.
