[In St. Louis, in 1883, the population density of 9.8 persons to the acre] is indeed a low density compared with that of most metropolitan cities: that of London, for instance, is given at 52.5 to the acre in 1883. And yet we find the annual rate of mortality per thousand in London in 1883 to have been but 20.4, while that of St. Louis was 21.35. With such a variance existing in the relative de...

HOVLAND and Sears (2) attempted to verify a causal relationship between economic frustration and aggressive behavior as expressed in lynchings by a statistical study. The statistical technique was as follows: linear trends were computed for the numbers of lynchings reported for the years 1882 to 1930, inclusive, in the United States. Two figures were available for each year, the total number of...

PASTURE PRODUCTION is logically measured in terms of grazing animals supported by that pasture. A simple calculation based on stock numbers and area in grassland in New Zealand shows that over the last forty years carrying capacity has increased from 1.4 to 3.2 “sheep units” per acre, or 130% (N.Z. Official Year Book). Obviously many factors have contributed to this increase, including improved...

In the Amazon region the phlebotomine fauna is considered one of the most diverse in the world. The use of Shannon traps may provide information on the anthropophily of the species and improve the traps' performance in terms of diversity and quantity of insects collected when white and black colored traps are used together. This study sought to verify the attractiveness of the traps to the phle...

Several studies suggest that exposure to environmental endocrine disrupters can reduce the number of male births, and therefore, the male proportion at birth (also denominated birth ratio or sex ratio at birth) can be used as a sentinel health indicator. This work aimed to analyze the trend of male births in Brazil, according to their distribution by states and capitals. An ecological descripti...

this study presents empirical evidence concerning the effect of different accounting standard on earnings management. prior studies have shown that accounting standards influence earnings management. tighter accounting standards regime restricts management’s descretion to manipulate accruals, and at the same time, induce more costly real earnings management activities. to investigate this iss...

pancreatic stent proximal migration is a well known complication of pancreatic duct stenting, which occurs in about 5-6% of cases. serious complications should be avoided by retrieval of the stent via different endoscopic techniques. we report a new technique previously reported only once (in a pancreatic duct with underlying pathology), to remove the proximally migrated pancreatic stent in a n...
