This articles aims at contributing to the literature on party systems by proposing a new method to classify political parties. The methodology is applied to Brazil by focusing on the description of the election results of small parties. Cluster analysis is employed to classify political party size based on their percentage of votes in the Brazilian states. The main findings indicate that classifying parties through cluster analysis is more objective than previous classifications. As a result of this method, the article shows that small parties exert little effect on electoral volatility in Brazil as well as small parties benefit less from the disproportionality between votes and seats than the larger ones. Keywords: Small parties; cluster analysis; electoral volatility; disproportionality. Electoral Performance of Small Parties in Brazil F or the average voter, small parties from now on, SPs are electorally weak, do not field strong candidates vote pullers and have no real chance of victory. Nonetheless, small parties are often cited by the specialized literature. In Brazil, these parties are seen as a bad influence and partly responsible for both high levels of volatility and fragmentation. Moreover, SPs are usually labelled as parasites of the Brazilian political system. The widespread belief is that these parties depend on the help of larger parties in coalitions: without the larger parties it would be impossible for the smaller ones to obtain seats in parliament. Despite these negative attributes, SPs have seldom been subject to specific analyses. The literature that do take into account party size typically forget to examine the impact of SPs on election results in any systematic way. What is the real impact of small parties on election results?

The lowest standard deviation value was obtained from the data of the capping system with sulfur at 28 days and with neoprene pads at 7 days. Observing the data presented in Figure [7] for mix 3, it is possible to point out that the values obtained using the diamond saw have the greatest divergence among the other systems, when its means are compared to the mean obtained using the grinding system. Also its sample standard deviation is the greatest.

The surface preparation system that uses neoprene pads in a retaining ring shows less divergence when its mean is compared to the mean obtained with the grinding system. The lowest standard deviation value was obtained from the data of the capping system with sulfur at 7 days and with neoprene pads at 28 days.

Observing the data shown in Figure [7] for mix 4, it is possible to point out that the values obtained using the diamond saw have the greatest divergence among the other systems, when its means are compared to the mean obtained using the grinding system. Its sample standard deviation is also the greatest, and that occurs for the data obtained at 7 and 28 days. The surface preparation system that uses neoprene pads shows less difference when its mean is compared to the mean obtained with the grinding system.

Figure [8] shows how the other surface preparation systems varied compared to the capping system with sulfur mortar, which is established by NM 77 AMN, [9] as the standard practice for capping hardened concrete specimens, as mentioned above. For values obtained at 28 days, the greatest divergence among the means lies with the system using the diamond saw. The lowest standard deviation value at 7 days refers to the data from the grinding system and it is equal to the capping system with neoprene pads at the age of 28 days.

Observing the data presented in Figure [8] for mix 2, it is possible to point out that the values obtained using the grinding system and the diamond saw system presented the same divergence among the other systems, when their means are compared to the mean obtained using the capping system with sulfur mortar.

The highest sample standard deviation value belongs to the system using the diamond saw, and the lowest to the capping system with neoprene pads for both ages of 7 and 28 days.

Observing the data from mix 3, it is possible to point out that the values obtained using the grinding system show the greatest divergence at 7 days and the capping system with neoprene at 28 days, among the other systems, when their means are compared to the mean obtained using the capping system with sulfur mortar. The highest sample standard deviation value belongs to the system using the diamond saw at the ages of 7 and 28 days. Still according to the data presented in Figure [8] for mix 4, it is noted that the grinding system has the greatest divergence among the other systems, while the system using the diamond saw has the lowest divergence, when their means are compared to the mean obtained using the capping system with sulfur mortar for both ages.

The largest sample standard deviation belongs to the system using the diamond saw, for both ages of 7 and 28 days.

For assistance with the validation of the research results, it was considered essential to conduct a statistical analysis in order to verify the variance performing a single-factor ANOVA. Initially, it was verified the hypothesis of normal distribution, as suggested by Medeiros [ 26 ] to apply that method.

The data distributions of all samples were considered normal. As previously stated, Triola [ 27 ] describes that when P has a small value, which is less than or equal to 0. Thus, it is possible to consider as valid all methods evaluated in this study, under the conditions described, as they presented P value, according to the ANOVA analysis, less than 0.

Given the potential for application of the test method which determines the compressive strength of concrete specimens - a property sensitive to changes in other properties -; an updated evaluation of the most widely used surface preparation procedures becomes essential, relating their results to the procedures established by the current standard practices in Brazil.

It was taken into consideration the two compressive strength groups established by NBR ABNT, [ 14 ], because the standard practice from , NBR ABNT, [ 28 ] includes in its text some different procedures for the design of reinforced concrete structures with strengths belonging to the two compressive strength groups.

The differences in the test results caused by failure to perform or inadequate application of a given surface preparation system may result in rejection of batches of concrete that should be accepted, or even worse, result in the acceptance of batches that should be rejected. This can interfere considerably in the durability and functionality of the structure. To carry out this research, it was determined the concrete mixes to be subjected to compression tests at ages of 7 and 28 days, with four top surface preparation techniques.

It was considered essential to evaluate these techniques in concrete within both compressive strength groups established by NBR ABNT, [14], since draftsmen have been largely using this second group, which was previously used only in special projects.

Observing the analysis of the results, it is possible to conclude that the system established by NBR ABNT, [5] proves to be very effective for the four strength levels analyzed in this research, considering their means and standard deviations presented for those strength levels. The capping system described by NM 77 AMN [14] proves to be effective only for the strength level of 20 MPa; for the other 3 strength levels, its effective strength did not reach the expected value, and it turned out to be lower than the results obtained with the grinding process.

This fact requires further studies regarding its application in concrete, especially those with high compressive strength.
