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

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

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

Despite the growing interest, Open Innovation (OI) in Intangible Assets (IAs) research is still fragmented and displays a limited contextual focus. This paper aims to provide a clearer view of these issues and represents a first step toward filling such research gap. A systematic literature review and a synthesis of high-quality contributions with a focus on a general overview of research on OI and IAs in OI processes have been carried out. By critically evaluating the current body of literature and definitions, we have moved a step further toward comprehending the multiple facets of existing research and highlight several promising areas for future development. In particular, we have analyzed the role of IAs in OI practices by selecting a synthesis and a critical review of their different exploitations. We have combined multiple algorithms to produce a clear topical taxonomy of the multiple strands of research lying at the interface of OI and IAs. 相似文献
