Child Abuse and Neglect: Perspectives on a National Emergency

Hundreds of thousands of children are being abused and neglected in the United States annually. The structures devised to respond to this abuse and neglect have been unsuccessful. The United States government continues to spend billions of dollars on programs to deal with the effects of these unsuccessful responses. Child abuse and neglect in the United States now represent a national emergency. In this article, we will provide a historical, cultural, and contemporary perspective on child abuse and neglect. This perspective throws light on the complexity of the national emergency and provides a context for further exploration of the issue.     

Pathological Dissociation as Measured by the Child Dissociative Checklist

The component structure of the Child Dissociative Checklist was examined among abused children. A factor described as pathological dissociation emerged that was predicted by participants being male. There also were differences in pathological dissociation between groups of sexually abused and physically abused children. Replication of this factor and the establishment of base rates for various groups of children are recommended so that the Child Dissociative Checklist might be used to more effectively eliminate false positives and increase true positives in the screening and ultimate treatment of dissociative children.     

Lesbians Grieving the Death of a Partner: Recommendations for Practice

ABSTRACT

Spousal loss is a common event that has been associated with risk of depression, anxiety, and loneliness. Practitioners working with lesbians need comprehensive clinical guidelines that integrate research about lesbian partner loss with contemporary views of grief and bereavement. Using this literature, we make recommendations for clinical practice that address the possible contributions of several factors—social support, emotional closeness, relationship satisfaction, disclosure or non-disclosure of sexual identity and the relationship, faith and/or spirituality, and meaning-making—to the grieving process and positive psychological adjustment of lesbians grieving the death of a partner.     

What Is Hooking Up? Examining Definitions of Hooking Up in Relation to Behavior and Normative Perceptions

Research has demonstrated ambiguity about the definition of hooking up among college students. The current research examined whether there were multiple definitions of hooking up among college students and how different definitions might be associated with the participant's own hooking up behavior and normative perceptions of peer hooking up behavior. A random sample (N = 1,468) of undergraduates (56.4% female) completed a Web-based survey composed of measures of drinking and sexual behavior. Open-ended definitions of hooking up were content-coded and analyzed using a mixture model to explore discrete definitions of hooking up among college students. Findings indicated three clusters of student definitions of hooking up: Cluster 1 had the broadest definition, referring to sex in general, not specific sexual acts, and to making out. Cluster 2 placed an emphasis on interpersonal and social aspects. Cluster 3 defined hooking up as sex with notable references to specific sexual acts. Results further indicated that hooking up behavior and normative perceptions differentiated these three groups of definitions. Clinical implications regarding the inconsistency of student definitions of hooking up and how they may impact negative consequences associated with hooking up are discussed.     

Nucleic acid amplification testing in suspected child sexual abuse

The American Academy of Pediatrics recommends that site-specific cultures be obtained, when indicated, for sexually victimized children. Nucleic acid amplification testing is a highly sensitive and specific methodology for identifying sexually transmitted infections. Nucleic acid amplification tests are also less invasive than culture, and this may provide an efficacious alternative for children suspected of being sexually abused.     

The transmission and effects of Wolbachia bacteria in parasitoids

Wolbachia bacteria are obligatory intracellular parasites of arthropods and have been detected in about 70 species of parasitic wasps and three parasitoid flies. Wolbachia are transmitted cytoplasmically (maternally) and modify host reproduction in different ways to enhance their own transmission: parthenogenesis induction (PI), cytoplasmic incompatibility (CI), or feminization (F) of genetic males. Only PI and CI are known in parasitoids. PI-Wolbachia cause thelytoky in otherwise arrhenotokous parasitoids by generating diploid (rather than haploid) unfertilized wasp eggs. CI-Wolbachia cause incompatibility of crosses between infected males and uninfected females because the paternally derived chromosomes fail to decondense and are destroyed after syngamy. More complex situations arise when hosts harbor multiple infections, which can lead to bidirectional incompatibility and may be involved in parasitoid speciation. The relative fitness of infected and uninfected hosts is important to the population dynamics of Wolbachia, and more data are needed. Evolutionary conflict should be common between host genes, Wolbachia genes, and other "selfish" genetic elements. Wolbachia-specific PCR primers are now available for several genes with different rates of evolution. These primers will permit rapid screening in future studies of spatial and temporal patterns of single and multiple infection. Molecular phylogenies show that CI- and PI-Wolbachia do not form discrete clades. In combination with experimental transfection data, this result suggests that host reproductive alterations depend on the interaction between attributes of both Wolbachia and host. Moreover, Wolbachia isolates from closely related hosts do not usually cluster together, and phylogenies suggest that Wolbachia may have radiated after their arthropod hosts. Both results support considerable horizontal transmission of Wolbachia between host species over evolutionary time. Natural horizontal transmisson between parasitoids and their hosts, or with entomoparasitic nematodes or ectoparasitic mites, remains a tantalizing but equivocal possibility.
