The sense and the nonsense of school effectiveness

Hanushek misinterprets the data on which he bases his conclusion and draws inappropriate policy implications from them. The goals of a school system affect how its resources are used. Educational goals are highly diverse. Accordingly, the measures of output used in Hanushek's studies are inappropriate. To develop more effective measures, the nature of the teaching and learning process must be much better understood. Fortunately, a solid beginning has already been made among specialists in education on that critical task; but more work is needed.     

Imagining (the) Difference: Gender,Ethnicity and Metaphors of Nation

This article critiques the way in which three feminist authors reinscribe traditional liberal values when seeking new ways of thinking about the nation. It suggests that in rejecting affective or embodied metaphors, such as community or kinship, the authors fall into the trap of reinscribing values which have historically excluded women and ethnic or racial minorities from full participation in the polity. The article argues for a rejection of the affect/rationality model which underpins these arguments and suggests that new metaphors for the nation will emerge as those who have been excluded claim a place in the polity.     

Perspective and procedural justice: Attorney and litigant evaluations of court procedures

A comparison of the procedural justice judgments of attorneys and those of lay people judging the same procedures offers an opportunity to generate new information on what factors affect judgments of fairness. In a survey of reactions to conventional and innovative procedures in a United States district court, attorneys and lay people involved in tort and contract cases were asked to judge the overall fairness of court procedures and the fairness of specific procedures used in arbitration hearings. The respondents were also asked for their judgments concerning the favorability of the procedure's outcome, the opportunity to have the case heard and decided by an impartial third party, and their side's control over what happened in the case, all of which are factors found in previous studies to affect procedural fairness judgments. The results showed that, while attorneys gave higher overall fairness ratings than did litigants, the difference was not affected by the procedure assigned to the case. In addition, attorneys and litigants appeared to use the same standards to evaluate the fairness of procedures, although they disagreed about where the procedures they experienced fell on these dimensions. The theoretical and practical implications of the results are discussed.     

Identifying chop marks on cremated bone: a preliminary study

The purpose of this analysis is to evaluate the effects of burning on hacking trauma inflicted with a cleaver and to assess the diagnostic potential of cleaver marks exposed to fire. Thirty pig forelimbs (radius and ulna) and 30 beef ribs were each subjected to five blows with a cleaver and five cuts with a knife prior to burning in an outdoor fire. Bones were deliberately agitated to ensure maximum cremation and induce fragmentation. Results indicate that hacking weakens bone, making fire-induced fragmentation more likely at the sites of trauma. Chop marks were easily identified on burned bone, their characteristics largely unaffected by cremation.     

Injuries of the Head from Backface Deformation of Ballistic Protective Helmets Under Ballistic Impact

Modern ballistic helmets defeat penetrating bullets by energy transfer from the projectile to the helmet, producing helmet deformation. This deformation may cause severe injuries without completely perforating the helmet, termed “behind armor blunt trauma” (BABT). As helmets become lighter, the likelihood of larger helmet backface deformation under ballistic impact increases. To characterize the potential for BABT, seven postmortem human head/neck specimens wearing a ballistic protective helmet were exposed to nonperforating impact, using a 9 mm, full metal jacket, 124 grain bullet with velocities of 400–460 m/s. An increasing trend of injury severity was observed, ranging from simple linear fractures to combinations of linear and depressed fractures. Overall, the ability to identify skull fractures resulting from BABT can be used in forensic investigations. Our results demonstrate a high risk of skull fracture due to BABT and necessitate the prevention of BABT as a design factor in future generations of protective gear.     

Gender Differences in Risk Markers for Perpetration of Physical Partner Violence: Results from a Meta-Analytic Review

There is a lack of consensus on whether the use of intimate partner violence (IPV) is distinctly different between men and women, or if men and women share similar risk markers for perpetrating IPV. In this study, we compared 60 different risk markers for IPV perpetration for men and women using a meta-analysis. We found three out of 60 risk markers significantly differed between men and women. Our results suggest that there are more similarities between men and women than there are differences in risk markers for IPV perpetration.     

Dynamics of Polarizing Rhetoric in Congressional Tweets

Affective polarization is pervasive in modern US politics, and can be intensified by strategic messaging from members of Congress. But there are gaps in our knowledge of the dynamics of polarizing appeals from elected representatives on social media. We explore the usage of polarizing rhetoric by members of Congress on Twitter using the 4.9 million tweets sent by members of Congress from 2009 to 2020, coded for the presence of polarizing rhetoric via a novel and highly accurate application of supervised machine learning methods. Fitting with our expectations, we find that more ideologically extreme members, those from safer districts, and those who are not in the president’s party are more likely to send polarizing tweets, and that polarizing tweets garner more engagement, increasing campaign funding for more polarizing members.
