Delirium is a common neurobehavioral syndrome that occurs across health care settings which is associated with adverse outcomes, including death. There are limited data on long-term cognitive outcomes following delirium. This report reviews the literature regarding relationships between delirium and cognitive impairment. Psych Info and Medline searches and investigation of secondary references for all English language articles on delirium and subsequent cognitive impairment were carried out. Nine papers met inclusion criteria and documented cognitive impairment in patients following delirium. Four papers reported greater cognitive impairment among patients with delirium than matched controls. Four papers reported higher incidence of dementia in patients with a history of delirium. One study found 1 of 3 survivors of critical illness with delirium developed cognitive impairment. The evidence suggests a relationship between delirium and cognitive impairment, although significant questions remain regarding the nature of this association. Additional research on delirium-related effects on long-term cognitive outcome is needed. 相似文献

Divergent perceptions of sexual harassment were explored in a case of a perpetrator's gradual sexual advancements and a target's escalating commitment to their relationship. Participants were 60 male and 60 female undergraduate students from a private midwestern university. Approximately 7% were minority members. Males and females interpreted the male perpetrator's actions differently, particularly when the female target made prior commitments to a friendly relationship. Specifically, males' ratings of sexual harassment decreased when the female target participated in increasingly informal, friendly interactions. Females ratings remained relatively constant despite the target's reactions. Attributions and reactions to the harassment also were influenced. Interestingly, as the target's commitment increased, both males and females reported a lower likelihood that the target would seek help.This study was part of the second author's master's thesis at Drake University. An earlier version of the study was presented at the 6th Annual Conference of the Society for Industrial and Organizational Psychology, St. Louis, Missouri, April 1991. The authors would like to thank John Binning, Michael Ford, William Klipec, Paula Radefeld, and LaVerne Rogers for their contributions to this research. 相似文献

This study examined ecological predictors of structural and moral commitment among cohabiting same-sex couples. Structural commitment was operationalized as the execution of legal documents, and moral commitment was operationalized as having a commitment ceremony. The authors tested 2 logistic regression models using a subsample of Rainbow Illinois survey respondents. First, the execution of legal documents was examined using the entire subsample (n=190). Because antigay victimization may sensitize individuals to the importance of legal protection, actual and feared victimization were hypothesized to predict legalization. These hypotheses were not supported. However, relationship duration, a control variable, did predict legalization. The authors then used data only from those individuals who had executed a legal document (n=150) to determine those who also reported a commitment ceremony (Model 2). Parental status, religiosity, involvement with a supportive congregation, and an interaction between gender and parental status were hypothesized to predict ritualization. Only religiosity and parental status emerged as significant. Results from this study demonstrate the importance of distinguishing between legalization and ritualization. Further, they extend knowledge about how same-sex couple commitment is shaped by noncouple factors, such as time, individual religiosity, and parental status. 相似文献

Access to and control of resources is a major source of costly conflicts. Animals, under some conditions, respect what others control and use (i.e. possession). Humans not only respect possession of resources, they also respect ownership. Ownership can be viewed as a cooperative arrangement, where individuals inhibit their tendency to take others’ property on the condition that those others will do the same. We investigated to what degree great apes follow this principle, as compared to human children. We conducted two experiments, in which dyads of individuals could access the same food resources. The main test of respect for ownership was whether individuals would refrain from taking their partner's resources even when the partner could not immediately access and control them. Captive apes (N = 14 dyads) failed to respect their partner's claim on food resources and frequently monopolized the resources when given the opportunity. Human children (N = 14 dyads), tested with a similar apparatus and procedure, respected their partner's claim and made spontaneous verbal references to ownership. Such respect for the property of others highlights the uniquely cooperative nature of human ownership arrangements. 相似文献

The framers of the U.S. Constitution believed that intellectual property rights were crucial to scientific advancement. Yet,
the framers also recognized the need to balance innovation, privatization, and public use. The courts’ expansion of patent
protection for biotechnology innovations in the last 30 years raises the question whether the patent system effectively balances
these concerns. While the question is not new, only through a thorough and thoughtful examination of these issues can the
current system be evaluated. It is then a policy decision for Congress if any change is necessary. 相似文献

Although several studies have examined inhibition of affective stimuli, valence-dependent cognitive control effects remain poorly understood. Behavioural and functional imaging (functional magnetic resonance imaging) data were collected from 17 healthy participants to examine neural correlates of the Negative Affective Priming (NAP) task. We created relative ratio scores considering the reaction times of prime trials in order to assess the amount of interference after the presentation of negative and positive distracter words. Behavioural results showed an attenuated NAP effect for negative distracters compared to neutral stimuli. Furthermore, priming negative distracters generated more interference by reacting to the probe target than positive distracters. Neuroimaging data revealed a stronger prefrontal activation during negative NAP trials compared to positive NAP and neutral control trials, which was reflected in a heightened activation of superior and middle frontal gyrus as well as parietal cortex. The findings show the impact of negative distracters on prefrontal response, contributing to the understanding of NAP effects in healthy subjects. 相似文献

The increasing availability of high-dimensional, fine-grained data about human behaviour, gathered from mobile sensing studies and in the form of digital footprints, is poised to drastically alter the way personality psychologists perform research and undertake personality assessment. These new kinds and quantities of data raise important questions about how to analyse the data and interpret the results appropriately. Machine learning models are well suited to these kinds of data, allowing researchers to model highly complex relationships and to evaluate the generalizability and robustness of their results using resampling methods. The correct usage of machine learning models requires specialized methodological training that considers issues specific to this type of modelling. Here, we first provide a brief overview of past studies using machine learning in personality psychology. Second, we illustrate the main challenges that researchers face when building, interpreting, and validating machine learning models. Third, we discuss the evaluation of personality scales, derived using machine learning methods. Fourth, we highlight some key issues that arise from the use of latent variables in the modelling process. We conclude with an outlook on the future role of machine learning models in personality research and assessment. 相似文献

Multicollinearity is a problem that can adversely affect the estimation of coefficients in regression equations. The types of regression models used as evidence in employment discrimination cases may be particularly susceptible to estimation problems resulting from multicollinearity, yet courts have in most instances failed to address this difficulty. This paper discusses the problems associated with multi- collinearity and suggests possible sources of the multicolli- nearity, particularly in the context of employment discrimination litigation. An academic example demonstrates how multicollinearity can be identified and corrected. Other possible techniques for curing the multicollinearity or reducing its effects are also presented. The related problem of “tainted” variables, often discussed by courts in employment discrimination litigation, is differentiated from the multicollinearity problem. For regression equations to be reliable and for inferences regarding discrimination to be accurately made, courts should concern themselves with multicollinearity, and not so-called “tainting.” 相似文献
