Positive psychological characteristics may be beneficial for physical health. However, prospective data on the effects of happiness on survival is scarce. In a population-based cohort study, the Arnhem Elderly Study, happiness was measured by two items, being: “I have many moments of happiness” and “I often laugh happily”. In Cox proportional hazard models, happiness was analyzed as a predictor of 15 year all-cause mortality for 861 (85%) of 1,012 elderly subjects aged 65–85 years. Results showed that happiness was inversely associated with mortality (age- and sex-adjusted hazard ratio of 0.78 for happy subjects versus unhappy subjects; 95% confidence interval 0.64–0.95, P = 0.01 for trend), but that this relationship was no longer statistically significant after adjustment for physical activity and prevalent morbidity. Thus, happiness predicts for lower mortality, which may partly be mediated by more physical activity and lower morbidity. 相似文献

Sunscreens with Titanium Dioxide (TiO<Subscript>2</Subscript>) Nano-Particles: A Societal Experiment
The risks of novel technologies, such as nano(bio)technology cannot be fully assessed due to the existing uncertainties surrounding
their introduction into society. Consequently, the introduction of innovative technologies can be conceptualised as a societal
experiment, which is a helpful approach to evaluate moral acceptability. This approach is illustrated with the marketing of
sunscreens containing nano-sized titanium dioxide (TiO2) particles. We argue that the marketing of this TiO2 nanomaterial in UV protective cosmetics is ethically undesirable, since it violates four reasonable moral conditions for
societal experimentation (absence of alternatives, controllability, limited informed consent, and continuing evaluation).
To remedy the current way nano-sized TiO2 containing sunscreens are utilised, we suggest five complementing actions (closing the gap, setup monitoring tools, continuing
review, designing for safety, and regulative improvements) so that its marketing can become more acceptable. 相似文献

A dynamic touch paradigm in which participants judged the lengths of rods and pipes was used to test the D. M. Jacobs and C. F. Michaels (2007) theory of perceptual learning. The theory portrays perception as the exploitation of a locus on an information manifold and learning as continuous movement across that manifold to a new locus, as guided by information available in feedback. The information manifold was defined as a 1-dimensional space of inertial variables. To encourage maximal learning, a 2-step procedure was used in each of 2 experiments. Each step comprised a pretest to identify the starting locus on the information manifold, a practice phase in which feedback specifying the optimal locus was given, and a posttest in which the ending locus on the manifold was identified. In the 2nd step, a different feedback variable specified a different optimum. In both experiments, participants, who sometimes began at different loci, showed the predicted movement toward the optimum in each phase. Whereas previous applications of the theory posit the existence of information-for-learning without identifying a candidate variable, such a candidate is identified. 相似文献

The Intensive Mental Health Program meets the needs for services in school systems for children with serious emotional disturbances
and for training graduate students in clinical applications with a difficult-to-serve population. We address the range of
challenges and rewards experienced in the development of the comprehensive intervention program, the continued maintenance
of program elements, and the program evaluation. 相似文献

The present study investigated the effects of anticipation on skin conductance while participants were answering a set of questions which included one of concealed knowledge. Two experiments were conducted. In Exp. 1, 26 participants completed one experimental session. Each participant was asked to choose one two-digit number from 10 to 99 and was presented 19 other randomly generated two-digit numbers. The list of numbers was then presented to the participant on a computer screen, with a 60-sec. interval occurring every two questions. The participant-selected number was defined as the target question which was randomly placed within the 4th to 17th item of 20 questions stated as follows: "Is your selected number?" The participant was asked to answer "No" to all questions. The skin-conductance response to each question was measured. In Exp. 2, the experimental procedure was the same as that in Exp. 1 except each participant first answered 10 nontarget questions, then answered a target question with the participant's selected number, and then answered another 10 nontarget questions. There were a total of 21 questions. Analysis indicated participants in both experiments generated the highest mean skin conductance while answering the target questions, followed by lower amplitudes to questions prior to and after the target question. The skin-conductance response pattern can be used to identify the psychological process of anticipation of concealed information. 相似文献

Six experiments found that manipulations that increase thought speed also yield positive affect. These experiments varied in both the methods used for accelerating thought (i.e., instructions to brainstorm freely, exposure to multiple ideas, encouragement to plagiarize others' ideas, performance of easy cognitive tasks, narration of a silent video in fast-forward, and experimentally controlled reading speed) and the contents of the thoughts that were induced (from thoughts about money-making schemes to thoughts of five-letter words). The results suggested that effects of thought speed on mood are partially rooted in the subjective experience of thought speed. The results also suggested that these effects can be attributed to the joy-enhancing effects of fast thinking (rather than only to the joy-killing effects of slow thinking). This work is inspired by observations of a link between "racing thoughts" and euphoria in cases of clinical mania, and potential implications of that observed link are discussed. 相似文献
