We investigate youths' conceptualization of social robots. Informed by Schudson's theory of the potency of the cultural object, we conducted two studies. The first study centered on essays on social robots written by bachelor's and master's students. The second study centered on prototypes of social robots built by small groups comprised of same students. The essays and prototypes were content analyzed. The results confirm that social robots embody all five dimensions that characterize cultural objects. However, to fully understand this peculiar cultural object, another dimension needs to be introduced: dynamicity. 相似文献

The aim of this work is to give a rigorous definition of likelihood without any reference to the peculiarities of Euclidean spaces, and is thus applicable to a larger class of problems with a more complex result space.Here we intend to offer the simplest possible discussion of the ideas on which likelihood methods are based, with some remarks about their links to some classical measure-theoretical concepts, such as Radon—Nikodym derivatives. Since the definition of likelihood relies on the topological structure of the result space, it is necessary to point out the connections that it has with the measure-theoretical one, mostly caused by the fact that singletons, i.e. the actual observable results, are usually measure-zero sets. 相似文献

AbstractThe purpose of this study was to determine whether aerobic plus resistance training (AT + RT) is more effective than aerobic training (AT) at reducing inflammatory markers and cardiovascular risk in obese adolescents. A total of 139 obese adolescents were enrolled, aged 15–19 years, body mass index (BMI) ≥ 95th percentile and participated in 1 year of interdisciplinary intervention. They were randomised into two groups: AT (n = 55), AT + RT (n = 61). Blood samples were collected to analyse glycaemia, insulin, the lipid profile, leptin and adiponectin concentrations. Insulin resistance was measured by homeostasis model assessment of insulin resistance index (HOMA-IR). The AT + RT group showed better results with regard to decreased body fat mass, low-density lipoprotein concentration (LDL-c) levels, subcutaneous and visceral fat and increased body lean mass. Indeed, a reduction of hyperleptinaemia and an increase in adiponectin concentrations, promoting an improvement in the leptin/adiponectin ratio, was observed. Important clinical parameters were improved in both types of exercise; however, AT + RT was more effective in improving the visceral adiposity, metabolic profile and inflammatory markers than AT alone, suggesting clinical applications for the control of intra-abdominal obesity and cardiovascular risk in the paediatric population. 相似文献

Students are generally known to memorise and regurgitate chemical equations without sufficient understanding of the changes
that occur at the particulate level. In addition, they often fail to recognise the significance of the symbols and formulas
that are used to represent chemical reactions. This article describes an evaluation of the ability of 65 Grade 9 students
(15–16 years old) from a Singapore secondary school to describe and explain seven types of chemical reactions using macroscopic,
submicroscopic and symbolic representations. The study was conducted over nine months using a supplementary teaching program
with particular emphasis on the use of multiple levels of representation to describe and explain chemical reactions. Students’
proficiency in the use of multiple levels of representation was assessed at the end of the course using a two-tier multiple-choice
diagnostic instrument that was previously developed by the authors. In order to evaluate the efficacy of the instructional
program, the instrument was also administered to another group of 76 students who were not involved in the supplementary instructional
program. The efficacy of the program was evident from the significantly improved scores on the diagnostic instrument of the
former group of students. In addition, several student conceptions in the use of multiple levels of representation were identified
that could assist teachers in their planning and implementation of classroom instruction. 相似文献
