The current study assesses the factor structure and construct validity of the self-reported Inventory of Callous-Unemotional Traits (ICU) in 637 Chinese community adults (mean age = 25.98, SD = 5.79). A series of theoretical models proposed in previous studies were tested through confirmatory factor analyses. Results indicated that a shortened form that consists of 11 items (ICU-11) to assess c...

BACKGROUND How is the perception of collaboration influenced by individual characteristics, in particular high levels of callous-unemotional (CU) traits? CU traits are associated with low empathy and endorsement of negative social goals such as dominance and forced respect. Thus, it is possible that they could relate to difficulties in interpreting that others are collaborating based on a share...

BACKGROUND The extent to which the State Children's Health Insurance Program (SCHIP) crowds our private insurance is poorly understood. OBJECTIVE To assess the incidence of crowd-out and enrollee characteristics associated with crowd-out. DATA Parent telephone survey for 2,644 children after enrollment in NY SCHIP. MEASURES AND ANALYSES: Crowd-out is measured based on enrollee reports of co...

Males in many bird species mimic the vocalizations of other species during sexual displays, but the evolutionary and functional significance of interspecific vocal mimicry is unclear. Here we use spectrographic cross-correlation to compare mimetic calls produced by male satin bowerbirds (Ptilonorhynchus violaceus) in courtship with calls from several model species. We show that the accuracy of ...

BACKGROUND Sickle cell trait (SCT) is the heterozygous form of sickle cell disease and expectedly should be a benign state with no complications ascribed to it. There are numerous reports challenging its being a benign condition, though this is controversial. METHODS AND RESULTS A review of the results of the accompanying investigations done on some of the patients show that beta thalassemia ...

An unexplained death in custody represents an important focal point for public scrutiny of the criminal justice system, especially when excess deaths occur in those of minority ethnic descent. Sickle cell anaemia is a serious inherited blood disorder disproportionately affecting minority ethnic groups. Sickle cell trait is the genetic carrier state and not an illness. The evidence suggests that...

The γ(G)-158 (C→T) polymorphism plays important function in the disease severity of sickle cell anemia. The XmnI restriction site at -158 position of the γ(G)-gene is associated with increased expression of the γ(G)-globin gene and higher production of HbF. This study aims to determine the frequency of the different genotypes of the γ(G) Xmn I polymorphism in sickle cell anemia and sickle cell ...

BACKGROUND Most (86%) of the global stroke mortality are from low- and middle-income countries (LMIC) including African countries which have the highest prevalence of the sickle cell trait (Hb AS). The effects of this trait on stroke occurrence and outcome are poorly understood. We aimed to investigate the effects of the sickle cell trait on the 30-day stroke mortality in Nigerian-Africans. M...
