Nature tourism in the Rio Grande Valley
Article Abstract:
The Lower Rio Grande Valley in Texas offers bird watchers an exhilarating view of special birds amidst a backdrop of border towns. The City of McAllen, in particular, provides excellent services to tourists including quick rides to spectacular nature spots. Nature tourism translates to big money for McAllen residents but its economic impact is next only to the educational rewards that such activities generate including a greater understanding of bird habitats.

The limits of nature and the educational nature of limits
Article Abstract:
There are limits to natural systems that cannot be surmounted by technology. Evidence that human life affects the global environment is mounting, and the global economy is predicated on increasing consumption. Technological responses to natural limits can cumulatively erode the ability to respond to those limits. Disbelief in natural limits is illogical. Humans need to precisely identify their limitations to set priorities and function freely.

Limits of retrospective power analysis
Article Abstract:
Power analysis is suggested to interpret results after a study has been completed. Three methods of estimating power are presented and their limitations are discussed. It is shown that estimated power can be extremely variable, biased and severely bounded. It is recommended that the relevant way to interpret study results is to calculate confidence intervals on the appropriate parameter.
