This study examines the sources of geographic variance in commercial Internet use. Until now, two opposing views have been argued on the relationship between Internet technology and economic agglomeration. One view, which we term global village theory, asserts that Internet technology helps lower communication costs and break down geographic boundaries between firms. The other view, labeled urb...

STRATEGIES FOR THE IMPROVEMENT OF RURAL CHICKEN PRODUCTION IN GHANA. Rural poultry production systems in Ghana and in Africa as a whole are based on the scavenging indigenous domestic fowl (Gallus domesticus), the predominant species in the poultry sector [1]. In most African countries scavenging chicken have no regular health control programmes, may or may not have shelter and usually have to ...

Research with a variety of genetic stocks has produced many important discoveries in the areas of genetics, virology, immunology, developmental biology, and animal agriculture. (see CRAWFORD 1990, for a review). These include the pioneering studies on Mendelian inheritance and sex determination of BATESON (1902), and BATESON and PUNNETT (1906, 1908). Not surprisingly, given its history of use i...

The thyroid stimulating hormone receptor gene (TSHR) has been suggested to be a "domestication locus" in the chicken. A strong selective sweep over TSHR in domestic breeds together with significant effects of a mutation in the gene on several domestication related traits, indicate that the gene has been important for chicken domestication. TSHR plays a key role in the signal transduction of sea...

The comparative study of proteins is being used with greater frequency to produce information concerning genetic differences among species. Such studies make it increasingly evident that there may not be a strict correlation between degree of genetic difference and degree of difference at the supramolecular or organismal level. This point can be illustrated by the results of comparing proteins ...

With the global village approaching a new era of aesthetic economy powered by culture creative, every country is actively seeking inspirational resources for culturally creative product design. Chinese traditional poetry, full of expression created with poets’ fascinating words and still highly appreciated today, carries not only our predecessors’ wisdom but also principles which correspond to ...

The study of intercultural communication has tried to answer the question, “How do people understand one another when they do not share a common cultural experience?” Just a few decades ago, this question was one faced mainly by diplomats, expatriates, and the occasional international traveler. Today, living in multicultural societies within a global village, we all face the question every day....

As part of an investigation of an encephalitis outbreak in New York City, we sampled 430 birds, representing 18 species in four orders, during September 13-23, 1999, in Queens and surrounding counties. Overall, 33% were positive for West Nile (WN) virus-neutralizing antibodies, and 0.5% were positive for St. Louis encephalitis virus-neutralizing antibodies. By county, Queens had the most seropo...
