The New Keynesian Phillips Curve is at the center of two raging empirical debates. First, how can purely forward looking pricing account for the observed persistence in aggregate inflation. Second, price-setting responds to movements in marginal costs, which should therefore be the driving force to observed inflation dynamics. This is not always the case in typical estimations. In this paper, w...

A 24-year-old African-American male presented with bowel obstruction secondary to incarcerated inguinal hernia and mesenteric fibromatosis. The latter diagnosis was delayed. Surgical correction of both etiologies was required. Our case represents an interesting combination of one of the most common ca...

This study examines the effects of visual appeal and usability on user performance and satisfaction with a website. Users completed search and exploratory tasks on sites which varied in visual appeal (high and low) and usability (high and low). Results indicate that first impressions are most influenced by the visual appeal of the site. Users gave high usability and interest ratings to sites wi...

This paper examines the theory of the Phillips curve, focusing on the distinction between “formation” of inflation expectations and “incorporation” of inflation expectations. Phillips curve theory has largely focused on the former. Explaining the Phillips curve by reference to expectation formation keeps Phillips curve theory in the policy orbit of natural rate thinking where there is no welfar...

We conducted a survey of the malaria vectors in an area where a power line had been constructed, between the municipalities of Porto Velho and Rio Branco, in the states of Rondônia and Acre, respectively. The present paper relates to the results of the survey of Anopheles fauna conducted in the state of Rondônia. Mosquito field collections were performed in six villages along the federal highwa...
