O artigo visa contribuir para ampliar o entendimento sobre o papel do seguro garantia na contratação de obras públicas no Brasil, destacando a contribuição do performance bond no processo de gestão dessas contratações públicas. Com esse propósito, o artigo revisa a origem da securitização, discutindo a sua relevância e aplicabilidade no setor público. Para ilustrar as vantagens econômicas desse mecanismo, foram analisados 72 contratos de obras públicas no estado da Paraíba, que evidenciam a recorrência dos problemas derivados da aditivação, como o atraso das obras, observado em todos os casos da amostra, e o aumento do custo dos projetos de, em média, 15% do valor inicialmente orçado. Os resultados indicam que a adoção de mecanismos mais adequados de securitização pode trazer benefícios significativos ao processo de contratação de obras públicas no Brasil.

And Training

The research aimed to identify managers’ conceptions of disability and the relationship that was established between these conceptions and their perception of the persons with disabilities (PWD) performance, bond, benefits of hiring, and training needs. 257 managers answered a questionnaire in order to identify conceptions of disability in organizations. Descriptive statistics, factorial analysis, and hierarchical analysis of grouping were performed while using IBM Statistic 20.0.0. The results show that managers who have the spiritual and the conception based on inclusion perceive the insertion of PWD as beneficial to the organization. Those who conceive disability as a question of normality perceive the PWD performance as inferior to those without disabilities, which implies that PWDs should be segregated; and, the managers who perceive disability as a social problem are likely to place PWDs in the workplace according to their potential. The results can be fruitfully used by managers, human resources’ professionals, academics, and the society to promote inclusion.

Pressure-pushing method of evaluation for adhesion strength of high performance coatings material and substrate is presented. This method, based on the pressure-testing device of high performance bond strength test sample patent, is one that the sample is cracking along the interface by putting the static load. According to the sample’s stress boundary conditions, the formula of the adhesion strength is given. The surface coating/substrate interface stress distribution is analyzed by using the finite element method, which provides the theory basis for the correct evaluation of coating/substrate strength. The experiments are conducted on the strength of common coating substrate materials as well. All the results show that pushed method can test the adhesion strength of high performance coatings and substrate, whose data is smaller than the international standard and A STMC633-79. And the experimental data of the pushed method are free from the influence of random factors.
