Canaletto’s paintings open a new window on the relative sea-level rise in Venice     

Dario Camuffo 《Journal of Cultural Heritage》2001,2(4):92

The paintings by Canaletto (1697–1768), made with the help of a camera obscura, are just like real photographs, documenting as they do the Venice of the XVIII century with an accurate reproduction of all the details. The brown–green front left by the Laminaria, an alga living between the high and low tide, constitutes a precise biological indication of the average level of the high tide. By comparing the level of this front at Canaletto’s time with the present level, we can calculate/discover the relative sea level rise which has occurred in the last two and a half centuries.  相似文献

Press releases and email notices increase local and global visibility of a small medical journal     

Dario Sambunjak 《Learned Publishing》2006,19(4):267-271

To increase its visibility among the general public and the international scientific community, the Croatian Medical Journal (CMJ), a small journal from the so‐called scientific periphery, introduced a media strategy of sending press releases to journalists and email notices to the newsdesk of a high‐profile international scientific journal. Subsequent news coverage and the positive response of journalists show that press releases and targeted email notices increased international visibility of articles published in a small scientific journal, and improved communication with journalists as mediators of scientific information to the general public.  相似文献   

Correlations between serum and salivary hormonal concentrations in response to resistance exercise     

Cadore E  Lhullier F  Brentano M  Silva E  Ambrosini M  Spinelli R  Silva R  Kruel L 《Journal of sports sciences》2008,26(10):1067-1072

The aim of present study was to examine the relationships between serum and salivary values of free testosterone, dehydroepiandrosterone, and cortisol before and after a session of resistance exercise. Twenty-eight healthy men (mean age 40 years, s = 4) participated in the present study. Serum and salivary samples were collected at rest and after a multiple-sets resistance exercise protocol, of approximately 25 minutes duration. Concentrations of free testosterone, dehydroepiandrosterone, and cortisol were measured using radioimmunoassay kits. No significant correlation was observed between serum free testosterone and salivary testosterone (r = 0.22 to 0.26, P > 0.05). Serum cortisol was significantly correlated with salivary cortisol before (r = 0.52, P = 0.005) and after (r = 0.62, P = 0.001) the exercise protocol. Serum and salivary concentrations of dehydroepiandrosterone were significantly correlated before (r = 0.68, P < 0.001) and after (r = 0.7, P < 0.001) exercise. The results of the present study suggest that even under exercise conditions, the salivary values of cortisol and dehydroepiandrosterone can reflect the behaviour of these hormones in blood. However, further studies are necessary to verify if salivary testosterone reflects the behaviour of serum free testosterone during resistance exercise.  相似文献   

The 2011 Benjamin Franklin Medal in computer and cognitive science presented to John R. Anderson     

Dario D. Salvucci 《Journal of The Franklin Institute》2014

John R. Anderson is an international leader in the computational representation and simulation of human cognition. He is credited as having developed the first “cognitive architecture”—a computational framework for specifying both the abilities and limitations of human behavior. Anderson has also made fundamental contributions in applying cognitive architectures to practical problems, most notably in the development of intelligent tutoring systems: computer-based tutors that continually infer the cognitive state of the student, striving to determine what the student knows and does not know, and targeting further instruction accordingly. For these achievements, Anderson was awarded the 2011 Benjamin Franklin Medal in Computer and Cognitive Science.  相似文献   

Integration and Physical Education: A Review of Research     

Risto Harri Juhani Marttinen  Gabriella McLoughlin  Ray Fredrick III  Dario Novak 《Quest (Human Kinetics)》2017,69(1):37-49

The Common Core State Standards Initiative has placed an increased focus on mathematics and English language arts. A relationship between physical activity and academic achievement is evident, but research on integration of academic subjects with physical education is still unclear. This literature review examined databases for the years 2004–2013, focusing on physical education or physical activity and core academic subjects for school-aged youth. 23 studies were found that focused on integration and physical education that met the inclusion criteria. These were from 16 different publication outlets, ranging in research methods, country, and population. This review provides information on the status of integration and physical education. Since classroom teachers are increasingly being encouraged to incorporate core subjects with physical activity into their classes, it would be appropriate for physical educators to understand the desired outcomes of integration of core subjects before attempting its implementation.  相似文献   

Math-gender stereotypes in elementary school children     

Cvencek D  Meltzoff AN  Greenwald AG 《Child development》2011,82(3):766-779

A total of 247 American children between 6 and 10 years of age (126 girls and 121 boys) completed Implicit Association Tests and explicit self-report measures assessing the association of (a) me with male (gender identity), (b) male with math (math-gender stereotype), and (c) me with math (math self-concept). Two findings emerged. First, as early as second grade, the children demonstrated the American cultural stereotype that math is for boys on both implicit and explicit measures. Second, elementary school boys identified with math more strongly than did girls on both implicit and self-report measures. The findings suggest that the math-gender stereotype is acquired early and influences emerging math self-concepts prior to ages at which there are actual differences in math achievement.  相似文献   

Comparison of power and EMG during 6-s all-out cycling between young and older women     

CR Duffy  D Stewart  F Pecoraro  PE Riches  D Farina  A Macaluso 《Journal of sports sciences》2012,30(12):1311-1321

Abstract To investigate the effects of ageing on the neural control strategies governing sprint cycling on a friction-loaded cycle-ergometer, 10 older (aged 70-83yr) and 8 young (aged 19-35yr) healthy women completed seven 6-s all-out cycling trials against varying loads. Root mean square (RMS), median frequency and muscle fibre conduction velocity were determined from the vastus lateralis of the dominant limb during each pedal stroke. Peak power was 43% lower in the older group compared to the younger (p??0.05). ΔRMS from the first to the sixth second during each trial was found to increase significantly with the development of power output in both groups (p?相似文献

Reduction of water evaporation in polymerase chain reaction microfluidic devices based on oscillating-flow   总被引：1，自引：0，他引：1

Producing polymeric or hybrid microfluidic devices operating at high temperatures with reduced or no water evaporation is a challenge for many on-chip applications including polymerase chain reaction (PCR). We study sample evaporation in polymeric and hybrid devices, realized by glass microchannels for avoiding water diffusion toward the elastomer used for chip fabrication. The method dramatically reduces water evaporation in PCR devices that are found to exhibit optimal stability and effective operation under oscillating-flow. This approach maintains the flexibility, ease of fabrication, and low cost of disposable chips, and can be extended to other high-temperature microfluidic biochemical reactors.  相似文献
