The relevance of hedonic price indices

We argue that for the case of heterogeneous commodities with infrequent tradings, such as paintings, it is relevant to base a price index on hedonic regressions using all sales and not resales only. To support this conclusion we construct a price index for paintings by Impressionists and their followers and compare the various estimators using bootstrapping techniques.     

Experience from the field: Programming in a joint-use partnership library

ABSTRACT

Librarians of the joint-use North Regional/Broward College (NR/BC) Library had sought opportunities to collaborate. Historically, challenges have arisen in programming for two distinct populations: seniors for the public library and the college library’s students. In recent years, the library successfully capitalized on organizational changes and nationwide attention to media literacy and social justice to create and deliver several well-received collaborations. This article describes the environment in which these initiatives developed and provides tips on collaborations in- and out-side joint-use libraries. This article also addresses the dearth of professional literature on programming advantages in joint-use libraries.     

Science Education at the National Institute for Pedagogical Research,Paris, France

This article explores the nature of a continuing mismatch between curriculum reform rhetoric in science education and actual classroom practice. Lack of philosophical consensus about the nature of science (NOS); lack of appropriate curriculum guidance, classroom materials and pedagogical content knowledge for NOS teaching; teachers’ personal theories of learning; and the realities of classroom constraints are all implicated as interacting factors that contribute to the mismatch. Because curriculum policy is political, with pressure brought to bear by many interest groups, it is suggested that the science teaching community cannot adequately address the issues raised in the absence of wider community debate and support.
