This study explored the relationship between metacognition and intelligence in a group of normal adolescents. The relationship has strong theoretical support in current conceptions of intelligence. For the purposes of this study metacognition was assessed across three different cognitive problem sets. Correlational analyses indicated a nonsignificant relationship between intelligence and metacognition. These results suggest that tests of metacognition and intelligence may tap unrelated aspects of cognition and that additional research will be required to understand the relationship between these two constructs. 相似文献

IntroductionTwo new formulas, the Martin-Hopkins and the Sampson formula, were recently developed to overcome shortcomings of the Friedewald formula for calculating LDL-cholesterol. We aimed to compare the concordance of the two formulas with apolipoprotein B (apoB), a surrogate marker of the number of LDL particles.Materials and methodsIn a study of serum lipid data of 1179 patients who consulted the AZ St-Jan Hospital Bruges for cardiovascular risk assessment, the correlation and concordance of the Friedewald, Martin-Hopkins and Sampson formulas with apoB concentration, measured by immunonephelometry, were determined and compared.ResultsThe Martin-Hopkins formula showed significantly higher correlation coefficient than the Friedewald formula with apoB in the entire dataset and in patients with low LDL-cholesterol < 1.8 mmol/L. Both Martin-Hopkins and Sampson formulas yielded > 70% concordance of LDL-cholesterol with regard to treatment group classification based on population-equivalent thresholds of apoB in hypertriglyceridemic patients (2-4.5 mmol/L), with the highest concordance (75.6%) obtained using Martin-Hopkins formula vs. 60.5% with Friedewald formula.ConclusionThe Martin-Hopkins (and, to a lesser extent, Sampson) formula is more closely associated with the number of LDL particles than Friedewald formula. This, in combination with literature evidence of lesser accuracy of the Friedewald formula, is an argument to switch from Friedewald to a modified, improved formula. 相似文献

The debate about whether the arts should be supported or not is far from new, and most governments support the arts in one
way or the other. The literature considers several arguments in favor of such interventions. Public education may seem to
be an action which could, in the long run, lead to possible reductions of subsidies. Surveys show that those who have been
exposed to the arts when young participate more when adult. However, the “non-market” transmission from parents to children
generates an external effect, which has to be taken into account to reach first-best situations. We construct an overlapping
generations model in which young consumers are exposed to both public education toward the arts and to non-altruistic transmission
of such a taste from their parents. We show that the first-best can be reached only if there is both public cultural education
and subsidization of arts consumption. Therefore, education cannot be considered as a substitute for subsidies to arts consumption.
However, as is often the case in European countries, government intervention is usually below the first-best level. Using
a model calibrated on French data, we show that it is then preferable to subsidize education, while consumption, especially
of the older generations, should be taxed rather than subsidized.

One of the major conceptual difficulties of environmental education is its complexity. During a 20 h module of initial training gathering together primary and secondary school teachers this concept was highlighted. Some approaches have been tested, all dynamic and transferable. They are analysed and assessed. 相似文献

This paper pays attention to two factors often neglected in the studies of instructional or guidance interaction: the specifity of the child as interlocutor and the constraints exerted by the properties of the tasks on the semiotic means used to guide the child. Following Sigel’s ‘distanciation hypothesis’ we have studied the ‘distancing’ characteristics of the adult’s discourse adressed to the child in two groups of dyads, one with deaf (N=5), the other with hearing children (N=7) aged around 24 months, in two tasks: Symbolic Play and Picture — Book reading. The main results indicate a strong effect of the tasks, SP allowing more distanciation than PB for both categories. D-dyads show few differences in SP task but less ability to share references in Picture-Book reading. It appears also that with such young children, the distancing potential might be conveyed by the forms and pragmatic functions and not only by the semantic components of adult’s utterances. 相似文献

This paper builds upon previous research that examines participatory forms of “reciprocal journalism” and “public communication” led by high school and college students in Miami, Florida, USA, in the fall of 2014. In this study, the students’ assessment of local and national media coverage is used to reveal greater details inherent in examining participatory methods of newswork. Collectively, students said that media coverage emphasis on local and national public officials instead of residents and community members who experience sea-level rise first-hand, combined with a lack of scientific explanation of and solutions for sea-level rise reduced the event's potential to build reciprocal relationships with younger audiences. 相似文献

The purpose of this study was to examine the relationship between the upper limb anthropometric dimensions and a history of dominant upper limb injury in tennis players. Dominant and non-dominant wrist, forearm, elbow and arm circumferences, along with a history of dominant upper limb injuries, were assessed in 147 male and female players, assigned to four groups based on location of injury: wrist (n = 9), elbow (n = 25), shoulder (n = 14) and healthy players (n = 99). From anthropometric dimensions, bilateral differences in circumferences and in proportions were calculated. The wrist group presented a significant bilateral difference in arm circumference, and asymmetrical bilateral proportions between wrist and forearm, as well as between elbow and arm, compared to the healthy group (6.6 ± 3.1% vs. 4.9 ± 4.0%, P < 0.01; ?3.6 ± 3.0% vs. ?0.9 ± 2.9%, P < 0.05; and ?2.2 ± 2.2% vs. 0.1 ± 3.4%, P < 0.05, respectively). The elbow group displayed asymmetrical bilateral proportions between forearm and arm compared to the healthy group (?0.4 ± 4.3% vs. 1.5 ± 4.0%, P < 0.01). The shoulder group showed significant bilateral difference in elbow circumference, and asymmetrical bilateral proportions between forearm and elbow when compared to the healthy group (5.8 ± 4.7% vs. 3.1 ± 4.8%, P < 0.05 and ?1.7 ± 4.5% vs. 1.4 ± 4.3%, P < 0.01, respectively). These findings suggest that players with a history of injury at the upper limb joint present altered dominant upper limb proportions in comparison with the non-dominant side, and such asymmetrical proportions would appear to be specific to the location of injury. Further studies are needed to confirm the link between location of tennis injury and asymmetry in upper limb proportions using high-tech measurements in symptomatic tennis players. 相似文献
