This paper extends Lucas (1978) to a production economy with two capital goods. It is an RBC model in which each unit of investment requires a new idea, an “option”. When options are scarce, new capital is harder to put in place and the value of old capital rises. Thus the stock market and Tobin’s Q are negative indexes of intangibles. During a boom, Q rises gradually, as options are used up. B...

The e+e− Linear Collider project, so called JLC, is the next principal project for research in high energy physics in Japan[1]. The JLC project consists of two experimental phases. The first phase (JLC-1) is an e+e− linear collider at 250 < √ s < 500GeV[2], and the second phase will extend the center-of-mass energy to > 1TeV[1, 3]. Although the JLC was originally proposed as a national project ...

The fact that people working with animals or their products may contract some infections has been known for centuries, before the introduction of the concept of zoonoses. Only recently, at least in Italy, was the prevention of occupational risks taken into account by legislation in spite of the fact that some zoonoses of livestock are of noticeable socio-economic importance. Nowadays some facto...

There is a strong need in the United States to increase the number of students from underrepresented groups who pursue careers in Science, Technology, Engineering, and Mathematics. Drawing from sociocultural theory, we present approaches to establishing collaborations between computer engineering and mathematics/bilingual education faculty to address this need. We describe our work through the ...

Frontiers of Business Cycle Research (hereafter referred to as Frontiers) is a collection of papers describing most of the important aspects of the real business cycle (RBC) research program pioneered by Kydland and Prescott (1982). A useful reference point for Frontiers is Lucas (1980), which describes developments in business cycle theory to the time when the RBC program was about to make its...

Our modified version of T-CLAP snowballs from a random adopter with depth d (three, in the case of our paper) and keeps pruning subscribers from this sample while the resulting community has more than s subscribers (115, in the case of our paper). H is the social network graph. H. S is the set of subscribers in this graph and A the set of adopters. The algorithm identifies the subscribers in H ...

Sir, the recent publication on “Publication Ethics” is very interesting (1). The article by Fazly Bazzaz and Sadeghi demonstrated many interesting cases                   of misconducts. Indeed, the misconducts can be seen  in many ways. As mentioned in the present publication, both author and editor can perform publication misconducts. Nevertheless, the problem has many more facets. Sometimes,...
