Putting a Finger on the Problem
Hispanic Profits
As I was staring at the option that popped up again at the Wal-Mart check out counter I began to realize that there is something even more clever than making the transaction painless. It's profit generating! Imagine spanish speaking buyers are the only ones for sure likely to choose the option of doing the transaction in spanish (except for few spanish tourists and language students). This makes them the only demographic group where merchants can mine expenditures and consumption data for. Sellers like Wal-Mart can figure out how sensitive they are to miniscule price changes, what kind of goods they like, when and how often they buy this and how much they spend on it as a fraction of their monthly grocery expenditures. All these information is important in trying to set up prices and stocking items that would maximize profits. Makes a lot of sense since the spanish speaking population is the fastest growing segment of americans.

Will Think for Food
Median annual wage and salary earnings of economists were $68,550 in 2002. The middle 50 percent earned between $50,560 and $90,710. The lowest 10 percent earned less than $38,690, and the highest 10 percent earned more than $120,440.
The Federal Government recognizes education and experience in certifying applicants for entry-level positions. The entrance salary for economists having a bachelor’s degree was about $23,442 a year in 2003; however, those with superior academic records could begin at $29,037. Those having a master’s degree could qualify for positions at an annual salary of $35,519. Those with a Ph.D. could begin at $42,976, while some individuals with experience and an advanced degree could start at $51,508. Starting salaries were slightly higher in selected areas where the prevailing local pay was higher. The average annual salary for economists employed by the Federal Government was $81,852 a year in 2003.Thursday, March 10, 2005

An evaluation of current perspectives on consciousness and pain in fishes | ||
Kristopher Paul Chandroo, Stephanie Yue & Richard David Moccia | ||
There is growing societal and scientific interest in the welfare status of fish used for commercial enterprise. As animal welfare is primarily concerned with the quality of life of a conscious, sentient organism, the question of whether fishes are even capable of consciousness must first be addressed in order to assess their welfare status. Recently, there has been a resurgence of research investigating the biological basis for human consciousness, and our current understanding of the cognitive mechanisms underlying fish behaviour has likewise improved significantly. Combined, these research perspectives create an opportunity to better comprehend the phylogeny of traits associated with consciousness, as well as the emergence of consciousness itself during vertebrate evolution. Despite the availability of this literature, contemporary reviews or published studies investigating the probability of conscious states occurring in fishes often do so without considering new perspectives or data. In this paper, we review and critique recent publications that report equivocal conclusions favouring the absence or presence of consciousness in various fishes. By introducing other data into these analyses, we demonstrate that there are alternative perspectives which support the existence of consciousness in fishes as a plausible concept. An accurate assessment of the mental capacity of fishes will require enhanced knowledge of their forebrain neuroanatomy, an understanding of how such structures mediate behavioural responses, and an analysis of that information within the context of contemporary theory related to the evolution of consciousness in higher vertebrates. |
