La inversión social en educación
Authors: Inza Bartolomé Amaia , Urteaga Olano Eguzki
Published: February 2019

Este artículo presenta la inversión en educación dentro de un enfoque más global que recoge la necesidad de concebir el gasto social no como un coste para la economía, sino como una inversión necesaria que redunde positivamente en el funcionamiento eficiente del Estado de bienestar. Se garantiza de esta manera un crecimiento duradero, fuerte y compartido que responda a las nuevas necesidades sociales. Se recoge aquí la literatura más relevante sobre la estrategia de la inversión social para destacar que una estrategia proactiva basada en la preparación y la educación a lo largo de la vida es fundamental ante los nuevos imperativos para prevenir en vez de limitarse a reparar. Por ello, se puntualiza la necesidad de mejorar la atención a la pequeña infancia, el sistema educativo en su globalidad y la excelencia universitaria dentro del planteamiento de la política social como factor productivo.

Safety in aviation - critical situations in the aspect of the theory of subjective analysis
Authors: Szafran Krzysztof
Published: February 2019

The article discusses one of the hypotheses of the theory of making decisions in emergency situations. The methodology developed in recent years to determine the probability of a dangerous situation, using subjective analysis, and in particular the function of entropy, gives a new look to the agent, as the decision-maker responsible for security in the structure of the active system. The following publication attempts to signal issues affecting the borderline of various areas of knowledge. Analogously to information theory, where the mathematics-computer scientist Claude E. Shannon introduced the probabilistic concept of entropy, it is possible to determine entropy in the considerations of the theory of choice, which is directly related to making decisions in critical situations. In some works, which were quoted in the paper, the function was called "subjective entropy". It is closely related to the concept of information value. It was shown how the use of the maximum entropy principle of a dynamic system's state can be an effective research instrument determining the security stock.

Authors: Kupiec Jerzy , Pikosz Zbigniew , Ślaski Grzegorz
Published: February 2019

The article presents the results of measurements and statistical analysis of the variables characterizing the braking process and the work of the car's braking system in diversified operating conditions. The introductory part presents a measuring system that allows measurements of brake system operation parameters during operation. Discussed are the methodology for measuring and determining such values as the temperature of the discs, unit pressures and the slip speed at the contact of the disc and brake pad, braking pressure, vehicle speed and its longitudinal acceleration. Operational working conditions included urban driving, extra-urban and motorway driving. Based on the measurements made, histograms of measured values were developed. On the basis of the obtained results, typical temperature gains during a single braking in individual conditions were determined and the course of temperature changes during cooling of the brake discs was analyzed. The ranges of typical values of the tested parameters for individual operating conditions were generalized and compared with the values characteristic for emergency braking, which can be considered as maximum values.

Esse trabalho consiste em um estudo etnográfico realizado em uma cooperativa de reciclagem, onde um dos pesquisadores atuou como trabalhador durante seis meses, investigando práticas de autogestão, politecnia e organização do trabalho. Os resultados obtidos ajudam a elucidar a maneira como os cooperados organizam/controlam seu próprio trabalho, bem como reproduzem práticas comuns às empresas tipicamente heterogestionárias. O principal aspecto condizente com organizações autogestionárias identificado foi a total autonomia dos cooperados para realizar mudanças no processo produtivo (e.g., arranjo físico, alterações no equipamento e no processo). Por outro lado, foram identificadas diversas características tipicamente presentes em empresas heterogestionárias: distanciamento entre gestão e produção, refletido na concentração das atividades administrativas e de coordenação em apenas dois funcionários; baixo nível de politecnia nas perspectivas da gestão da organização e da coordenação dos membros, restringindo o controle sobre o trabalho (alocação dos postos); e precarização do trabalho (condições ruins, variabilidades diversas e questões de segurança). Assim, alguns fatores, tais como o baixo nível de formação escolar e conhecimento técnico dos membros, a pressão por desempenho do ambiente concorrencial capitalista que está inserida e a reprodução de ferramentas e discursos de gestão tipicamente utilizados em empresas de mercado, contribuem para que a cooperativa tenha que dobrar seus esforços para conciliar aspectos da dialógica autogestionária-heterogestionária.

Objetivou-se avaliar o nível de sustentabilidade dos produtores rurais em quatro municípios do Sertão da Paraíba, analisando a contribuição dos indicadores quanto à qualidade de vida, preservação ambiental e capital social. Os dados foram obtidos, mediante aplicação de questionário com 40 produtores rurais de cada município e, com base nestes dados, foram calculados os índices de qualidade de vida, capital social e ambiental, para, então, definir o índice de sustentabilidade. Nos municípios do Sertão paraibano estudados, verificou-se que, segundo os produtores rurais, as atividades pecuárias que apresentam melhor desempenho econômico são a caprinocultura, a apicultura e a bovinocultura. Dentro das atividades agrícolas, destacam-se a fruticultura e a cultura de sequeiro. Em relação ao índice de qualidade de vida, todos os municípios foram caracterizados como nível médio. Para o índice de capital social, apenas Triunfo foi definido como baixo nível, os demais foram classificados como médio. O município de Santa Helena apresentou índice ambiental de médio nível de preservação, sendo as caracterizações dos demais municípios de baixo nível. A sustentabilidade dos produtores rurais, dos municípios de São João do Rio do Peixe, Santa Helena e Poço de José de Moura foi definido como médio. O município de Triunfo foi classificado como de baixo nível de sustentabilidade dos produtores rurais o qual teve contribuição negativa da baixa preservação ambiental e pequena participação social dos produtores.
