Background
Previous research has identified a number of variables that constitute potential risk factors for victimization and revictimization. However, it remains unclear which factors are associated not only with childhood or adolescent victimization, but specifically with revictimization. The aim of this study was to determine whether risk recognition ability and other variables previously associated with revictimization are specifically able to differentiate individuals with childhood victimization only from revictimized individuals, and thus to predict revictimization.Methods
Participants were N = 85 women aged 21 to 64 years who were interpersonally victimized in childhood or adolescence only, interpersonally revictimized in another period of life, or not victimized. A logistic regression analysis was conducted to examine whether risk recognition ability, sensation seeking, self-efficacy, state dissociation, shame, guilt, assertiveness, and attachment anxiety predicted group membership.Results
The logistic regression analysis revealed risk recognition ability, attachment anxiety, state dissociation, and self-efficacy as significant predictors of revictimization. The final model accurately classified 82.4% of revictimized, 59.1% of victimized and 93.1% of non-victimized women. The overall classification rate was 80%.Conclusions
This study suggests that risk recognition ability, attachment anxiety, self-efficacy, and state dissociation play a key role in revictimization. Increased risk recognition ability after an interpersonal trauma may act as a protective factor against repeated victimization that revictimized individuals may lack. A lack of increased risk recognition ability in combination with higher attachment anxiety, lower self-efficacy, and higher state dissociation may increase the risk of revictimization. 相似文献2.

Subtypes of the calcium-independent receptors for alpha-latrotoxin (CIRL1-3) define a distinct subgroup within the large family of the seven-transmembrane region cell surface receptors. The physiological function of CIRLs is unknown because neither extracellular ligands nor intracellular coupling proteins (G-proteins) have been identified. Using yeast two-hybrid screening, we identified a novel interaction between the C termini of CIRL1 and -2 and the PSD-95/discs large/ZO-1 (PDZ) domain of a recently discovered multidomain protein family (ProSAP/SSTRIP/Shank) present in human and rat brain. In vitro, CIRL1 and CIRL2 interacted strongly with the PDZ domain of ProSAP1. The specificity of this interaction has been verified by in vivo experiments using solubilized rat brain membrane fractions and ProSAP1 antibodies; only CIRL1, but not CIRL2, was co-immunoprecipitated with ProSAP1. In situ hybridization revealed that ProSAP1 and CIRL1 are co-expressed in the cortex, hippocampus, and cerebellum. Colocalization was also observed at the subcellular level, as both CIRL1 and ProSAP1 are enriched in the postsynaptic density fraction from rat brain. Expression of all three CIRL isoforms is highly regulated during postnatal brain development, with CIRL3 exhibiting its highest expression levels immediately after birth, followed by CIRL2 and finally CIRL1 in aged rats. 相似文献

Shoot tips from accessions of wild cherry (Prunus avium L.) selected from British woodland, and also theP. avium rootstock cvs. F12/1 and Charger, were successfully establishedin vitro, and most were easily micropropagated on Murashige and Skoog (MS)-based media. In one accession, adventitious shoots occasionally
developed from the extrafloral nectaries positioned at the base of leaf petioles of the initial explants. Micropropagation
of cv. Charger was improved by culture on a Quoirin and Lepoivre and Woody Plant-based medium, and by supplementing the medium
with 1-phenyl-3-(1, 2, 3-thiadiazol-5yl)urea (thidiazuron). Poor shoot production by F12/1 on 1, 3, 5-trihydroxybenzene (phloroglucinol)-free
media was not improved by up to 18 months of regular subculture. Study of cv. F12/1 showed that shoots produced on a MS-based
medium with 1 mM phloroglucinol, 0.49 μM indolebutyric acid, 4.4 μM benzyladenine (BA) and 0.29 μM gibberellic acid (GA3), were easier to root over several subcultures than shoots produced on a similar medium with no GA3 and only 2.2 μM BA, but only in a rooting medium supplemented with 1 mM phloroglucinol. 相似文献
