This paper proposes a price index for artists adjusted for the quality of the paintings, based on the ratio between the average market price and the average pre-sale estimate for paintings. We apply this methodology to a group of selected artists and schools presented in auctions worldwide in the period 1990–2001. A comparison with quality unadjusted and hedonic indices is also conducted.JEL Classification: C10, Z11 相似文献

A qualitative study of the impact of electronic journals on the information behavior of academic researchers at Catalan universities shows that academic researchers now read more, and more widely. However, their reading is becoming more superficial; they are compelled to improve their discrimination skills in order to decide what to read in more depth. The electronic accessibility of journals means that researchers now make fewer library visits. Web browsing and table of contents (TOC) e-mail alerts are replacing physical browsing, and searching is a very popular option for keeping up to date with developments. Internet search engines, especially Google and Google Scholar, are becoming important sources of information for researchers. However, they face problems in managing their personal scientific information. 相似文献

This is an ethnographic study of the trajectories and itineraries of undergraduate physics students at a Mexican university.
In this work learning is understood as being able to move oneself and, other things (cultural tools), through the space–time
networks of a discipline (Nespor in Knowledge in motion: space, time and curriculum in undergraduate physics and management.
Routledge Farmer, London, 1994). The potential of this socio-cultural perspective allows an analysis of how students are connected through extended spaces
and times with an international core discipline as well as with cultural features related to local networks of power and construction.
Through an example, I show that, from an actor-network-theory (Latour in Science in action. Harvard University Press, Cambridge,
1987), that in order to understand the complexities of undergraduate physics processes of learning you have to break classroom
walls and take into account students’ movements through complex spatial and temporal traces of the discipline of physics.
Mexican professors do not give classes following one textbook but in a moment-to-moment open dynamism tending to include undergraduate
students as actors in classroom events extending the teaching space–time of the classroom to the disciplinary research work
of physics. I also find that Mexican undergraduate students show initiative and display some autonomy and power in the construction
of their itineraries as they are encouraged to examine a variety of sources including contemporary research articles, unsolved
physics problems, and even to participate in several physicists’ spaces, as for example being speakers at the national congresses
of physics. Their itineraries also open up new spaces of cultural and social practices, creating more extensive networks beyond
those associated with a discipline. Some economic, historical and cultural contextual features of this school of sciences
are analyzed in order to help understanding the particular way students are encouraged to develop their autonomy. 相似文献

In this work, we elaborate on the meaning of metadata quality by surveying efforts and experiences matured in the digital library domain. In particular, an overview of the frameworks developed to characterize such a multi-faceted concept is presented. Moreover, the most common quality-related problems affecting metadata both during the creation and the aggregation phase are discussed together with the approaches, technologies and tools developed to mitigate them. This survey on digital library developments is expected to contribute to the ongoing discussion on data and metadata quality occurring in the emerging yet more general framework of data infrastructures. 相似文献

In this paper, we present a model for the marketability of a Tribal artwork, and we test this model empirically using a unique hand-collected dataset, which comprises the worldwide Tribal art market auctions between 1999 and 2008. Our results show a significant relationship between the probability of an artwork to be sold and several signs and signals. The effect of the auction estimated prices on the probability of sales is nonlinear and allows us to divide the Tribal art market into two price regimes. In the low-price regime, the effect of the auction estimated price on the probability of sales is negative. In the high-price regime, the effect of the auction estimated price on the probability of sales is positive. 相似文献

ResumenEn este artículo se analiza el contexto interactivo que propicia la participación de los alumnos en la construcción social del conocimiento de ciencias naturales en la escuela primaria. La descripción se centra en las intervenciones de los alumnos, elaboradas en interacción con el docente, en las que expresan explicaciones alternativas y argumentan sus ideas. 相似文献

In the paper we develop some price indices for the secondary market forprints and drawings in Italy for the period 1977–1999. Theempirical evidence suggests the emergence of causal links from thepainting series and consumer price series to the print and drawingsprice series. Within the secondary market, the drawings price seriesprecedes the print price series. 相似文献

This study aimed to gather the opinions of editors of Library and Information Science journals indexed in Scopus and the Web of Knowledge regarding the current situation and their forecasts on open access, peer review procedures, functionalities, and specialization. The response rate was 23%, and some noteworthy conclusions can be drawn according to editors' opinions: Within 5–10 years, the main business model for journal publishing will be open access. Institutional support is the preferred source of financing. The review process requires less than 2 months, and the main problems are low quality of texts and finding reviewers. Functionalities such as mobile versions of the journals, social media, data policy, and altmetrics have yet to be exploited; interdisciplinarity will increase the presence of these functionalities in journals, especially through the influence of the related areas of Communication, Management, and Computer Science. Finally, the area that will see the most changes is the management of research data. 相似文献

This paper proposes a price index for modern andcontemporary paintings based on estimates and auctionprices. We use this index for the evaluation of theItalian art market and for comparisons with returns onother assets. During the period 1983–1994 art pricesincreased in line with inflation but returns onpaintings were lower than returns on financial assets.In the long run art prices are unrelated to financialassets prices, but a positive correlation with realestate prices emerges. 相似文献
