Techniques For Group Decision Making


This technique intended to overcome the pressures of conformity in the group interaction that delays the onset of creative alternatives. And this is achieved using a generator of ideas that feed all options without preventing them critical process.

In a typical brainstorming session of ide as, between 6 and 12 people sitting around a table. The group leader makes the problem clearly so that all participants understand. And then they have, with absolute freedom, all the alternatives that are occurring in certain period. No criticism allowed, and all alternatives aimed to discuss and analyze them later. The fact that an idea stimulates another and that the judgment of even the most unlikely of suggestions not until later encourages participants to think about the unusual.

However, brainstorming is but a process for generating ideas.

Nominal group techniques

This technique limits the discussion or interpersonal communication during the process of decision making. Group members are physically present, as in the traditional committee meeting, but operate independently. It is specifically formulated problem and then the following steps occur:

1. Participants meet as a group but before starting the discussion, everyone writes their own ideas about the problem.
2. The period of silence happens presenting an idea by each member. All members take turns going around the table, and expose a single idea until all have been displayed and recorded. The discussion begins when all the ideas have been noted.
3. The group discusses the clarity of ideas and evaluates them.
4. Each member of the group ranks the ideas silently and independently. The final decision is based on the idea that achieves the highest overall rating.

The main advantage of the nominal group technique is that it allows the group formally meet, but not limited to independent thinking much as it does the group interaction.

University of California


The University of California was founded in 1868 and its main campus is located in Berkeley, specifically in the Bay of San Francisco. It is a public university, where currently 35 409 students are enrolled.

The degrees awarded by the university include bachelor, master, doctoral and professional degrees. College programs are organized in schools and colleges, which are: Chemistry, Engineering, Environmental Design, Letters and Sciences, Natural Resources, Education, Journalism, Business, Public Policy, Information, Law, Optometry, Public Health and Social Welfare.

Visas For Japan


If you have thought about going to Japan to study, spend some time looking for a job or will need a visa to stay in the country legally.

There are different types of visas will try to summarize the three that matter most.

 To get this visa first have to do the paperwork in the country. The procedures are harder for Asian but for the rest of the world just have to certify that they have hired a school to study and someone in the country has sufficient funds to maintain the student for the period of the visa. Basically it is to show that the family can repay studies, enclosing documents of the bank or paying in advance. This visa allows you to work up to 20 hours a week in a job that is not among the category of hazardous.



In the chain polymerization reaction is triggered by the formation of a chemical species active, call initiator, which can be constituted by a radical, a carbocation or a carbanion. The initiator sum recursively upon himself a monomer molecule, shifting the center of reactivity (the unpaired electron, the electric charge) at the end of the chain As this grows. The production process of a polymer chain is divided into 3 phases: activation, propagation, and termination.

An example of a polymer obtained by chain polymerization is polyethylene.

In the presence of a high temperature or pressure the double bond between the carbon atoms breaks down and is replaced with a covalent single bond. At each carbon atom compete then 7 electrons in the outermost energy level. To meet the demands of bond, the monomer is combined with other monomers of ethylene, thus ensuring that each carbon atom shares four covalent bonds. The polymerization can take place thanks to the presence of a double covalent bond between the carbon atoms in the molecule of the reagent. The double bond (together with the triple bond) is said "unsaturated bond"; it is constituted by two links that have binding forces of different entities: the bond σ (stronger) and the bond π (weaker). The breaking of the bond π generates a chemical species unstable (called radical) that can be counted along additional monomers, lengthening the chain.

The concentration of monomer in the reaction in the case of chain polymerization decreases with constant speed. The yield for this type of polymerization is high, and the polymers that are obtained have a lower degree of polymerization than those obtained in the polymerization in stages.
