Political Awareness and Electoral Campaigns: Maximum Effects for Minimum Citizens?

Revisionists demonstrate campaigns mobilize, educate, activate predispositions, and change minds. Attention has turned from the “minimum effects” thesis to questions about the conditions under which campaigns matter and questions about which types of people are susceptible to campaign effects. Focusing on whether campaign effects are mediated by chronic political awareness, I find that current scholarship on this question is mixed. Some find that campaigns affect the politically unaware most, some find bigger effects among more aware citizens, and some find similar effects across the awareness distribution. Noting the possibility that awareness mediates different types of campaign effects differently (e.g. priming, persuasion, or learning), Zaller’s Receive–Accept-Sample framework is consulted to develop expectations. I test the RAS generated predictions using the 2004 National Annenberg Election Survey pre/post panel. The results support the theory that awareness mediates different campaign effects differently.     

The consequences of perpetrating psychological aggression in dating relationships: a descriptive investigation

Psychological aggression is the most prevalent form of aggression in dating relationships, with women perpetrating as much, if not more, psychological aggression than men. Researchers have advocated for an examination of the consequences that follow psychological aggression for the perpetrator, in hopes that this will lead to innovative intervention programs aimed at ameliorating dating violence. The current study investigated the self-reported consequences of having perpetrated psychological aggression against a dating partner among female college students in a current dating relationship (N = 115). Participants endorsed numerous consequences as having followed their perpetration of psychological aggression, including both punishing and potentially reinforcing consequences. Furthermore, findings indicated that for some perpetrators, psychological aggression may function as a method of emotion regulation. Implications of these findings for future research and intervention are discussed.     

Colonization of diatoms in and on porcine bone substrate and considerations of diatom ecology for forensic science

The presence of diatom algae in bone marrow has been used as forensic evidence of drowning for several decades; however, these studies are based on known or suspected recent drowning events. This study addresses the potential for diatoms to enter the bone marrow of skeletal remains, that is, de-fleshed long bones post-mortem. In laboratory and field experiments, bones were either inflicted with two access points by a cut and acid pitting or left intact. The bones were submerged in water for at least 1 week and up to 3 months. Samples of the bone surface and marrow were inspected for diatoms. The analysis considered the time required for diatoms to enter marrow and whether genus characteristics like size or mobility affect entry. The presence of an access point influenced diatom entry in that bones without an introduced access point had zero to one diatom present in the marrow, whereas a bone with an access point had >150 diatoms present in the marrow. The results of both laboratory and field phases suggest that diatoms will reliably colonize bone in as quickly as 1 week, establishing and maintaining communities for at least 3 months. However, the bone surface assemblages differ from the source community. Bone marrow displayed even more restrictive access to diatom colonization, resulting in communities dominated by small raphid diatoms. Based on these findings, we suggest some caveats on the use of diatoms as trace evidence in forensic science with recommendations for future avenues of research.
