This is the first of two papers examining housing market search in a Los Angeles market. In this paper, we derive and analyze utility functions for housing for each individual in two groups of subjects. The utility functions are derived from an experimental setting, in which house price, floor space, construction quality, and neighborhood quality are varied. The functions are found to be essentially compatible with a linear model. They are used to predict the ratings of real houses and the ratings of the expected value of future search. These ratings are compared with actual ratings obtained from subjects during search. The results suggest that the actual or predicted ratings may be employed in a direct test of a simple expected utility theory of search, and further research along these lines appears justified.

The authors redesign the user interface of an online library catalog, leveraging current Web technologies that allow dynamic and fine-grained user interaction. Over the course of their iterative design and test cycle, they identified four key areas where such dynamic Web technologies can be used to improve the support for typical information seeking strategies, namely: 1) the use of overview + details, 2) a tabular data display, 3) using tabs as a history mechanism, and 4) embedding a suggestion bar. The authors believe that the revised affordances created by their changes in these four areas will inform the design of future search interfaces.

In this paper, we select some of the crucial issues for future search and rescue (SAR) operations in the Barents Sea. The different nations that are involved and the resources necessary to build emergency preparedness due to the climatic conditions are thus important factors. This paper summarizes the state of the art within these areas while also indicating future development needs. The special requirements for life saving equipment on vessels due to the climate and requirement on personal protective equipment related to accidental immersion are also essential and thus presented in this paper. In addition, safe haven designs where the vessel itself is designed to provide shelter for personnel in distress is also a topic chosen to be addressed.

Septal fibrosis is a common form of hepatic fibrosis, but its etiology and pathogenesis are poorly understood. Rats infected with the helminth Capillaria hepatica constitute a good experimental model of such fibrosis. To investigate the pathogenetic contribution of the several parasitic factors involved, the following procedures were performed in rats: a) regarding the role of eggs, these were isolated and injected either into the peritoneal cavity or directly into the liver parenchyma; b) for worms alone, 15-day-old infection was treated with mebendazole, killing the parasites before oviposition started; c) for both eggs and worms, rats at the 30th day of infection were treated with either mebendazole or ivermectin. Eggs only originated focal fibrosis from cicatricial granulomas, but no septal fibrosis. Worms alone induced a mild degree of perifocal septal fibrosis. Systematized septal fibrosis of the liver, similar to that observed in the infected controls, occurred only in the rats treated with mebendazole or ivermectin, with dead worms and immature eggs in their livers. Thus, future search for fibrogenic factors associated with C. hepatica infection in rats should consider lesions with both eggs and worms.
