Objective: Weight-based discrimination negatively influences health, potentially via increased willingness to engage in unhealthful behaviours. This study examines whether the provision of genomic obesity information in a clinical context can lead to less willingness to engage in unhealthy eating and alcohol consumption through a mediated process including reduced perceptions of blame and discrimination.
Design: A total of 201 overweight or obese women aged 20–50 interacted with a virtual physician in a simulated clinical primary care environment, which included physician-delivered information that emphasised either genomic or behavioural underpinnings of weight and weight loss.
Main Outcome Measures: Perceived blame and weight discrimination from the doctor, and willingness to eat unhealthy foods and consume alcohol.
Results: Controlling for BMI and race, participants who received genomic information perceived less blame from the doctor than participants who received behavioural information. In a serial multiple mediation model, reduced perceived blame was associated with less perceived discrimination, and in turn, lower willingness to eat unhealthy foods and drink alcohol.
Conclusion: Providing patients with genomic information about weight and weight loss may positively influence interpersonal dynamics between patients and providers by reducing perceived blame and perceived discrimination. These improved dynamics, in turn, positively influence health cognitions. 相似文献
Given the growing interest in the study of subjective well-being as a measure of social progress, instruments that produce valid and reliable scores and that can be used within and across countries are needed. The aim of the present study was to analyze the measurement equivalence of the Day Reconstruction Method in its brief version, using nationally representative samples from Finland, Poland, and Spain obtained within the COURAGE in Europe project. The goodness-of-fit of a two-correlated-factors model and the reliability of the scores obtained were assessed. Cross-country invariance was tested employing a multiple group confirmatory factor analysis, through sequential constraint imposition. In each country, measurement invariance was tested across time frames (morning, afternoon and evening) and days of the week (weekday and weekend). The results found support for the hypothesis of a two-correlated-factors (positive and negative affect) structure; the reliability of the positive, the negative and the net affect scores showed appropriate values. A high equivalence across the three national samples was found: all items except one showed strong measurement invariance indicating that respondents from Finland, Poland, and Spain attribute the same meaning to the latent construct under study, and the levels of the underlying items are equal in all three countries. Similar results were found for the measurement equivalence across time frames and days of the week. Our findings support the assumption of comparability across the different samples considered; in general, higher positive affect and lower negative affect were found in Finland, in the evening and at the weekend. 相似文献
The aim of this paper is to apply properties of the double dual endofunctor on the category of bounded distributive lattices
and some extensions thereof to obtain completeness of certain non-classical propositional logics in a unified way. In particular,
we obtain completeness theorems for Moisil calculus, n-valued Łukasiewicz calculus and Nelson calculus. Furthermore we show some conservativeness results by these methods.

We investigate uniform interpolants in propositional modal logics from the proof-theoretical point of view.
Our approach is adopted from Pitts’ proof of uniform interpolationin intuitionistic propositional logic [15]. The method is
based on a simulation of certain quantifiers ranging over propositional variables and uses a terminating sequent calculus
for which structural rules are admissible.
We shall present such a proof of the uniform interpolation theorem for normal modal logics K and T. It provides an explicit
algorithm constructing the interpolants.

The authors applied linear dynamic models to longitudinal data to examine the dynamics of reading and cognition from 1st to 12th grade. They used longitudinal data (N=445) from the Connecticut Longitudinal Study (S. E. Shaywitz, B. A. Shaywitz, J. M. Fletcher, & M. D. Escobar, 1990) to map the dynamic interrelations of various scales of the Wechsler Intelligence Scales for Children--Revised (i.e., Full, Performance, and Verbal) and specific markers of the Woodcock-Johnson Psycho-Educational Battery--Revised reading cluster (i.e., Letter-Word ID, Decoding, and Comprehension). The results of these analyses indicate that (a) there is a positive dynamic relation between reading and cognition across the selected age range; (b) this dynamic relation is symbiotic, with positive influences in both directions; (c) the influence from cognition to reading is stronger when considering the Wechsler Intelligence Scales for Children Performance--Revised Performance scale and weaker with the Verbal scale; (d) when examining the different Reading subtests, the influences from cognition are more apparent for Letter-Word ID and Comprehension and are less perceptible for Decoding; and (e) the dynamics of reading and cognition appear to be of stronger magnitude during 1st to 3rd grade, less strong during 4th to 8th grade, and weaker from 9th to 12th grade. 相似文献
The acetylcholinesterase reversible inhibitor N-octyl-1,2,3, 4-tetrahydro-9-aminoacridine (THA-C8) is a new synthesized derivative of tacrine (THA) characterized by an alkyl chain in the molecular structure which ameliorates the penetrability of the compound into the central nervous system. THA-C8 (0.1-5 mg/kg) significantly reduced spontaneous locomotor activity in CD1 mice at a dose of 3 mg/kg. Moreover, THA-C8 (0.2-2 mg/kg) significantly improved shuttle-box avoidance acquisition at doses (0.25, 0.3, 1 mg/kg) not affecting locomotion and that are much lower than the doses reported to be effective for THA in animal models. From the data reported it seems that the new compound could be interesting for therapeutic purposes. 相似文献
Different European nation-states use the most diverse statistical constructions of foreign origin or ethnic minority populations. Several countries traditionally even shun from producing such data. This makes international comparison a very difficult endeavour. Anyone wanting to perform comparative research on immigrants or (immigrant origin) ethnic minorities in Europe is unavoidably confronted with the most diverse types of national statistical data and has to opt for ad hoc solutions. Attempts at international comparison can thus be very tricky due to data characteristics. It is important that researchers are aware of these problems and do not simply accept data (especially in comparisons) at face value. In this article we embark on a comparative explorative study of the way in which immigrant background and immigration related ethnicity is taken stock of by national statistical institutes in a set of European nation-states. 相似文献
ABSTRACT— Research has shown that experience acquired in infancy dramatically affects face-discrimination abilities. Yet much less is known about whether face processing retains any flexibility after the 1st year of life. Here, we show that early experience with an individual infant face can modulate the recognition performance of 3-year-old children and the perceptual processes they use to recognize infant faces ( Experiment 1 ). Similar experience acquired in adulthood does not produce measurable effects ( Experiment 2 ). We also show that the effects of early-acquired experience with an infant face become dormant during development in the absence of continued experience ( Experiment 3 ) and can be reactivated in adulthood by reexposure to the original experience ( Experiment 2 ). Overall, the results indicate that early experience can preserve the face-processing system from the loss of plasticity that would otherwise take place between childhood and adulthood. 相似文献
This study focused on the daily activities and related quality of experience of two distinct groups of Italian high school students analyzed in 1986 and 2000. Altogether, 120 participants, aged between 15 and 18, were administered the experience sampling method, a procedure providing on-line repeated samplings of daily time budget and associated quality of experience. In particular, attention was paid to optimal experience, characterized by a balance between environmental challenges and personal skills, intrinsic motivation, involvement, and well-being. In spite of the time gap, no major differences in the daily activity distribution were detected. Adolescents in both groups spent most of their time studying at school and at home, interacting, watching TV, carrying out maintenance, and engaging in structured leisure activities. The use of new technologies (computers, internet, mobile phones) emerged in the data gathered in 2000. As concerns the quality of experience, each daily activity showed a specific experiential profile recurring in both groups. Studying at home and engaging in structured leisure activities were primarily associated with optimal experience, as was using new technologies in 2000. These results shed light on students' preferential engagement in specific domains and allowed us to explore the active role of adolescents in shaping their future. Findings also highlighted the importance of providing adolescents with meaningful activities in order to foster their personal growth, well-being, and social integration. 相似文献
