Amisulpride is a substituted benzamide derivative that acts as a selective dopamine D2/D3 receptor antagonist. Although the anti‐aggressive properties of neuroleptic drugs are well known, the effects of amisulpride on agonistic interactions have not been explored, and there are no studies comparing acute and subchronic effects of this compound on aggression in rodents. In this study, we examined the action of amisulpride (5–25 mg/kg, i.p), administered acutely or subchronically for 10 days, on agonistic behavior elicited by isolation in male mice. Individually housed mice were exposed to anosmic "standard opponents" 30 min after drug administration, and the encounters were videotaped and evaluated using an ethologically based analysis. After acute treatment, amisulpride (5–20 mg/kg) exhibited an ethopharmacological profile characterized by a marked decrease of offensive behaviors (threat and attack) without an impairment of motor activity. By contrast, the anti‐aggressive action of the highest dose used (25 mg/kg) was accompanied by a weak increase of immobility. Body care was also significantly enhanced after treatment with the drug (20 and 25 mg/kg), emphasizing the involvement of dopaminergic receptors in this behavior. After subchronic treatment, no tolerance to amisulpride anti‐aggressive activity was observed. Overall, this behavioral profile is similar to that observed by other atypical neuroleptics. Aggr.

The present study assessed fathers' and mothers' relative involvement in infant caregiving tasks in 34 low-income African–American and Hispanic–American families. Analysis showed that involvement in childcare differed as a function of the gender of the parent. Fathers spent one half the time mothers did in caregiving. However, fathers' and mothers' participation in caregiving did not vary as a function of ethnic group. African–American parents reported to have received more family support than Hispanic–American parents. Although relationships were noted between age, income, education, length of marriage, social support, and involvement in infant caregiving, these sociodemographic variables did not predict parents' participation in childcare. The results are discussed in relation to the preconceived notion that low-income, minority fathers are ‘uninvolved’. ©1997 John Wiley & Sons, Ltd. 相似文献

This paper addresses multicriteria decision problems in which only partial information is given in the decision-making process. We generalize existing results about preference relations induced by nonnegative inverse matrices, allowing linear relations on weights with upper and lower bounds. In addition we develop conditions for additional information that preserve the special properties studied and show how to incorporate the new information to the model. © 1998 John Wiley & Sons, Ltd. 相似文献

This special issue highlights work that contributes to our understanding of health disparities and community-based participatory research (CBPR) approaches to promoting health equity across diverse populations and issues that matter to communities. We take on a global perspective, and thus, various efforts across international contexts are illustrated. Articles elucidate a variety of CBPR approaches designed to empower and build capacity among individuals and communities in order to seek changes at the level of community practices, programs, and systems. These articles span across diverse populations—children, youth, and families; adults and older adults; immigrants; refugees; Black people; Latinx people; Native Americans/Indigenous people, the Roma community; Muslim women, and women with disabilities—experiencing inequities of interest to community psychologists and other researchers and practitioners. 相似文献

Attenuated responding to a conditioned stimulus (CS) after preexposure to that CS (latent inhibition) has traditionally been attributed to reductions in CS associability. Alternatively, CS-context associations formed during CS preexposure later interfere with the acquisition or expression of CS-outcome associations. Three lick suppression experiments with rats contrasted these accounts. Presumably, exposure to the context attenuates the CS-context association without altering CS associability. With a fixed amount of CS preexposure, latent inhibition decreased with increasing context exposure during or after (but not before) CS preexposure. When the ratio of context preexposure duration to CS preexposure was fixed, latent inhibition increased with CS preexposure. These results suggest that latent inhibition is a direct function of the strength of CS-context associations formed during preexposure. 相似文献
