Critical-care decision making is highly complex, given the need for health care providers and organizations to consider, and constructively respond to, the diverse interests and perspectives of a variety of legitimate stakeholders. Insights derived from an identified set of ethics-related considerations have the potential to meaningfully inform inclusive and deliberative policy development that aims to optimally balance the competing obligations that arise in this challenging, clinical decision-making domain. A potential, constructive outcome of such policy engagement is the collaborative development of an as-fair-as-possible dispute resolution process that incorporates an appropriated-justified, defensible critical-care obligation threshold.  相似文献

According to appraisal theory, emotions result from an individual's meaning analysis of the implications of his/her circumstances for personal well-being, and individual differences in emotion arise when individuals appraise similar situations differently. Relational models of appraisal attempt to describe the situational and dispositional antecedents of appraisals, and should allow one to predict such individual differences. In this article, we review three examples of our efforts toward developing relational appraisal models. In two, we start with a particular appraisal component, motivational relevance and problem-focused coping potential (Smith & Lazarus, 1990), respectively, and describe and test the relational model proposed for that component. In the third, as a precursor to developing a true relational model, we examine another appraisal component, emotion-focused coping potential, from a more dispositional perspective. We conclude by considering both the potential value of relational appraisal models, and future directions in the development of these models.  相似文献

Distinguishing between relational and physical aggression has become a key feature of many developmental studies in North America and Western Europe, but very little information is available on relational and physical aggression in more diverse cultural contexts. This study examined the factor structure of, associations between, and gender differences in relational and physical aggression in China, Colombia, Italy, Jordan, Kenya, the Philippines, Sweden, Thailand, and the United States. Children ages 7–10 years (N = 1,410) reported on their relationally and physically aggressive behavior. Relational and physical aggression shared a common factor structure across countries. In all nine countries, relational and physical aggression were significantly correlated (average r = .49). Countries differed in the mean levels of both relational and physical aggression that children reported using and with respect to whether children reported using more physical than relational aggression or more relational than physical aggression. Boys reported being more physically aggressive than girls across all nine countries; no consistent gender differences emerged in relational aggression. Despite mean‐level differences in relational and physical aggression across countries, the findings provided support for cross‐country similarities in associations between relational and physical aggression as well as links between gender and aggression.

This study provides the first analyses connecting individual differences in infant attention to reading achievement through the development of executive functioning (EF) in infancy and early childhood. Five‐month‐old infants observed a video, and peak look duration and shift rate were video coded and assessed. At 10 months, as well as 3, 4, and 6 years, children completed age‐appropriate EF tasks (A‐not‐B task, hand game, forward digit span, backwards digit span, and number Stroop). Children also completed a standardized reading assessment and a measure of verbal intelligence (IQ) at age 6. Path analyses on 157 participants showed that infant attention had a direct statistical predictive effect on EF at 10 months, with EF showing a continuous pattern of development from 10 months to 6 years. EF and verbal IQ at 6 years had a direct effect on reading achievement. Furthermore, EF at all time points mediated the relation between 5‐month attention and reading achievement. These findings may inform reading interventions by suggesting earlier intervention time points and specific cognitive processes (i.e. 5‐month attention).  相似文献

Language maps signals onto meanings through the use of two distinct types of structure. First, the space of meanings is discretized into categories that are shared by all users of the language. Second, the signals employed by the language are compositional: The meaning of the whole is a function of its parts and the way in which those parts are combined. In three iterated learning experiments using a vast, continuous, open‐ended meaning space, we explore the conditions under which both structured categories and structured signals emerge ex nihilo. While previous experiments have been limited to either categorical structure in meanings or compositional structure in signals, these experiments demonstrate that when the meaning space lacks clear preexisting boundaries, more subtle morphological structure that lacks straightforward compositionality—as found in natural languages—may evolve as a solution to joint pressures from learning and communication.  相似文献

Children from families with low socioeconomic status (SES) earn lower grades, perform worse on achievement tests, and attain less education on average than their peers from higher‐SES families. We evaluated neurocognitive mediators of SES disparities in achievement in a diverse sample of youth whose data were linked to administrative records of performance on school‐administered tests of 7th grade reading and math proficiency (N = 203). We used structural equation modeling to evaluate whether associations between SES (measured at ages 8–9) and achievement (measured at age 13) are mediated by verbal ability and executive function (measured at age 10), a suite of top‐down mental processes that facilitate control of thinking and behavior. Children from relatively higher‐SES families performed better than their lower‐SES peers on all neurocognitive and achievement measures, and SES disparities in both reading and math achievement were partially mediated by variation in executive function, but not verbal ability. SES disparities in executive function explained approximately 37% of the SES gap in math achievement and 17% of the SES gap in reading achievement. Exploratory modeling suggests that SES‐related variation in working memory may play a particularly prominent role in mediation. We discuss potential implications of these findings for research, intervention programming, and classroom practice.  相似文献

Currently, over 4.3 million children are receiving special services within the nation's schools because of physical, developmental, and educational disabilities. It is estimated that twice this number would benefit from special education services. Public Law 94–142, the Education for the Handicapped Act, offered the first real opportunity for many children with disabilities to receive special health and educational services. Public schools have become a primary setting for provision of services to these children, however, many states have encountered difficulty in procuring funding. One federally mandated source of revenue is the Medicaid program. In the fall of 1991, all state Medicaid and special education programs were asked to provide information concerning current or planned use of Medicaid funds for special education services. Responses were received from 36 states. Only 19 states reported using Medicaid funding in any capacity, and of these, only four required schools to bill Medicaid for services rendered. The majority of these programs are in the pilot stages of development. Special education services covered by Medicaid vary widely, as do reimbursement mechanisms. All 19 states allow Medicaid coverage for speech, physical, and occupational therapy. Only about half of those states provide allowances for diagnostic evaluation and assessment, while coverage for psychological services is provided by three-fourths of those states, and EPSDT screens by half of the states. Only two programs had been evaluated formally at the state and/or federal level. Medicaid remains a largely untapped source of revenue that could be used to help fund services for disabled children.  相似文献

Some psychologists involved in the implementation of applied behavioral psychology in educational systems must increasingly attend to the ecological impact of such interventions. An ecological orientation emphasizing system-like interdependencies among environment, organism, and behavior suggests several substantial additions to conventional role functions of behavioral school psychologists. Such functions involve taking an active part in evaluating and assessing second-order consequences of behavioral interventions. Recommendations for functional and procedural changes are provided within this framework.  相似文献
