Universal health care, American style: a single fund approach to health care reform

With increasing momentum for health care reform, attention is shifting to finance reform that will provide for direct methods for controlling health care spending. This article outlines the two principal paths to direct cost control and outlines a national plan that retains our multiple sources of payment, yet also contains a powerful direct cost control technique: a single fund to finance all health care.     

Monogeusia for fructose,glucose, sucrose,and maltose

We investigated the ability of subjects to discriminate sugars with a whole-mouth forced-choice paradigm, in which a standard solution was compared with a test solution of varied concentration. Discrimination probabilities were U-shaped functions of test concentration: for 6 subjects and pairwise combinations of fructose, glucose, and sucrose, discriminability always declined to chance over a narrow range of test concentrations. At concentrations ≦ 100 mM, maltose was indiscriminable from fructose but discriminable at higher concentrations for 4 subjects. By analogy with themonochromacy of night vision, whereby any two lights are indiscriminable when their relative intensities are suitably adjusted, we call the gustatory indiscriminability of these sugarsmonogeusia. The simplest account of monogeusia is that all information about the indiscriminable sugars is represented by a single neural signal that varies only in magnitude. The discriminability of maltose from the other sugars at higher concentrations is consistent with the hypothesis that maltose also activates a second gustatory code.     

Social competence in early childhood: An empirical validation of the SOCIAL model

Social skills are the basis of human interactions and functioning in society. Social competence (SC) is thought to evolve gradually during childhood and adolescence via the interplay of multiple factors. In particular, the early years of life are marked by the emergence of basic social abilities and constitute the foundation for successful social development. The biopsychosocial SOcio-Cognitive Integration of Abilities modeL (SOCIAL) posits that internal (child-based), external (environment), and cognitive factors are critical to SC in the context of normal brain maturation; but this has yet to be shown empirically and comprehensively. This study tested the SOCIAL model in a sample of typically developing preschool children. Parents of 103 children (M = 67.59 months, SD = 11.65) completed questionnaires and children underwent neuropsychological assessment of executive functioning (EF), communication skills and social cognition. Three-step hierarchical regression analyses (1) Internal factors, 2) External factors, 3) Cognitive factors) confirmed that each step of the regression model significantly predicted SC. In the final model, general cognitive and socio-cognitive factors significantly predicted SC above and beyond internal and external factors: children with lower temperamental negative affect and less parent-reported executive dysfunction, as well as better non-verbal communication and theory of mind had better SC. Our findings support the conceptual SOCIAL model, and highlight the importance of internal, external, and cognitive factors for SC in the preschool years. Identification of factors associated with early social development can inform both normative and clinical approaches to identifying intervention loci and optimizing SC in those at risk for maladaptive social functioning.

Does the Need for Role Clarity Moderate the Relationship between Role Ambiguity and Athlete Satisfaction?

The purpose of the present study was to investigate the need for role clarity as a potential moderator of the role ambiguity–satisfaction relationship among interdependent sport athletes. Competitive “Junior B” ice hockey players (N = 112) representing eight teams completed the Role Ambiguity Scale, five subscales of the Athlete Satisfaction Questionnaire, and a measure of need for role clarity at approximately the mid-point of their competitive season. Correlational findings indicated that greater role ambiguity was associated with lower athlete satisfaction. However, consistent with the moderator hypothesis, the relationships between role ambiguity and various manifestations of satisfaction were only evident for those athletes who had a higher need for role clarity. Implications of the results are discussed and several avenues for application and future research are suggested.     

The Home-Based Occupational Therapy Intervention in the Alzheimer's Disease Multiple Intervention Trial (ADMIT)

There is no way to prevent functional declines related to Alzheimer's Disease (AD). The use of occupational therapy (OT) has been shown to be successful in managing some aspects of AD. We added home-based OT to evidence-based best practice for AD with the aim of delaying functional decline in people with AD. OT was delivered in the home to a caregiver dyad including the person with AD and her/his caregiver. This article describes the OT intervention for the AD Multiple Intervention Trial, a parallel randomized controlled trial. We include baseline data on the 180 caregiver dyads.     

The human capacity to transmit olfactory information

Monell Chemical Senses Center and Department of Otorhinolaryngology and Human Communication University of Pennsylvania, Philadelphia, Pennsylvania 19104 Previous estimates of the capacity of the olfactory channel are uniformly low. Either olfaction is considerably more limited than vision and audition or its capacity has been underestimated. It was suggested that underestimation may be due to use of stimuli having low levels of information or lack of laboratory training. Here, whole odors from objects were used. Naive Ss performed at levels consistent with earlier reports, and evidenced effects of prior experience in identifying the odors. With training, a much greater capacity than found previously was observed. It appears that the odors of single compounds and objects differ in information, dimensionality, or patterning, much like color patches and pictures or tones and words differ.     

Examining the link between adult attachment style,employment and academic achievement in first semester higher education

Although previous research indicates that both employment and adult attachment style have an influence on academic achievement, the interaction of these two factors has not been clarified. The purpose of this study was to investigate the moderating effect of adult attachment style on the relationship between employment status and first semester academic achievement in higher education. A sample of 378 freshman college students answered a series of questionnaires (Academic Amotivation Inventory, the Relationship Questionnaire and demographic), and their high school averages and first semester academic results were obtained from the Registrar’s office. The Analysis of covariance showed that employment status (having employment vs. no employment) and adult attachment style of students (secure vs. dismissing) strongly interacted in predicting academic achievement (first semester average adjusted for high school average, perceived financial burden, and amotivation). More specifically, the first semester averages of secure students with or without employment, and that of dismissing students without employment was indistinguishable. However, dismissing students with employment had significantly lower first semester averages than the secure students. This study showed that dismissing students entering postsecondary education who also have employment are at greater risk of academic difficulties than students with a secure attachment style.
