THE TRIAL AND ERROR METHOD


Commissioning Plan traffic by reordering the Government of the City of Buenos Aires, has shown a marked inefficiency is revealed in the implementation of measures based on erratic trial-error method.

Elias James Corey
won the 1990 Nobel Prize in chemistry for developing the theory and methodology of organic synthesis known as retrosynthetic method ¨ ¨, which is subject to final organic molecule is to synthesize a series of dissections in stages, according to a set of simple rules, taking into account the nature and the structural context of the links are broken. The analysis generated in this way, a tree of possible routes of synthesis. Corey was also able to understand the potential power of computers to aid in the analysis of hundreds of intermediate products that can be a retrosynthesis. With the method can estimate the simplest route to a new molecule. Prior to the work of Corey, the organic synthesis of compounds was mainly based on trial and error.

When a reporter from a prestigious journal devoted to science, asked how he came to get the results of their work without resorting to the classic appeal that his colleagues used trial and error, Corey said: ¨ Just a technical team surrounding me- able scientist, to study the behavior of all stakeholders, using a logical reasoning ... ¨

How far are the inhabitants of the City Buenos Aires to hear from those responsible for the city government, words such as Corey. For the Head of Government and its officials there is no possibility of organizing the traffic of the city, which continue to apply experimental methods based on trial and error.

worst thing is that these experiments are carried out risking the lives of people and are conducted by staff with low qualifications, technically limited and without recognition in the field, showing also an unacceptable degree of intolerance, arrogance and arbitrariness and a marked contempt for the efficiency and effectiveness in the administration of public money.

Proof of this is the path, making up and subsequent lifting of exclusive use lanes for public transport in Santa Fe Avenue and Callao between Libertador and implementation of a collective check rails for Rivadavia Avenue, between Jean Jaures and Ecuador, which lasted only one hour because they had no into account the turning radius on the corner of Jean Jaures and groups could not bend. The parking meters in several neighborhoods of the city, was carried far and soon raised it did not produce the results expected by enforcement authorities, who again spent public funds for enforcement is impractical.
Implementation of dual hand Pueyrredón Avenue is another measure that demonstrates improvisation and misguided policies on traffic management. Increasing environmental pollution and noise, the new traffic jams on streets where none occurred, the increase in travel times, the barrier to entry simple and straightforward to renowned and busiest health centers and schools, the change in the appearance and idiosyncrasies of the neighborhood and the countless road accidents that occurred in the two-way avenue, which have thrown the balance of a dead person, more than a dozen wounded including several children, is the result of applying a contains no risk as measured and serious lack of technical support, on a pilot basis temporary and based on trial and error.

The test-error test is a non-optimal as it tries to find only one solution, not all solutions, not the best solution. It is a very appropriate to exercise the learning and creativity, but not for the implementation of public policies that affect thousands of people.

Managing Head of the City Government must not only be for the common good, but also to respect the spirit and letter of the Constitution of the Autonomous City of Buenos Aires that promotes, encourages and provides for the participation of residents in implementing policies that provide solutions to their problems and in addition take into account the response of Corey .. Just surrounding myself with technical-scientific team capable to study the behavior of all stakeholders, using a logical reasoning ... ¨

When facilitate the participation, the best result is achieved, the test is recommended link http: / / www.youtube.com/watch?v=oMkCyc_uQQM
