The increase in the number of motorcycles in large Brazilian cities is due to several factors such as traffic, low cost, mobility, few parking lots and the low efficiency of public transportation, becoming an important factor in air quality deterioration. In this context, vehicle emissions monitoring is essential to understand the contribution to air pollution as a whole. In this scenario, the emissions were sampled on a motorcycle dynamometer test bench and analyzed by gas chromatography and on-line analyzers according to the EC/97/24 standard (European Commission). Emissions from motorcycles using commercial gasoline (with 22% of ethanol) were used in combination with meteorological data and ambient air pollutants for Rio de Janeiro City (Brazil) during the Winter of 2011, using the trajectory model OZIPR (Ozone Isopleth Package for Research) and the chemical model SAPRC99 (State-wide Air Pollution Research Centre) to assess the impact on the ozone formation in the troposphere of Rio de Janeiro for the next several years. The results indicate that ozone levels will exceed the established limits by national legislation within three years. The study also showed that pollutant emission rates stay in agreement with emissions recommended by the Brazilian legislation for all phases. The increase in ozone concentration occurs due to high emissions of reactive volatile organic compounds in an atmosphere with high levels of nitrogen oxides (NOx). Given this scenario, additional measures are necessary to manage emissions from mobile sources in the future.

The increased number of motorcycles in the large Brazilian cities is due to several factors such as traffic, low cost, mobility, few parking lots and low efficiency of public transportation, making it an important factor in air quality deterioration. In this context, vehicle emissions monitoring is essential to understanding the contribution on air pollution. Emissions of two representative motorcycles using gasohol (gasoline with 22% of ethanol) were evaluated on a dynamometer test bench and analyzed by gas chromatography mass spectrometry and on-line analyzers according to the EC/97/24 standard. Emission data obtained in combination with meteorological data and ambient air pollutants for the city of Rio de Janeiro (Brazil) during the winter of 2011, using the trajectory model OZIPR and chemical model SAPRC to assess the impact on the ozone forming potential in the troposphere of Rio de Janeiro city for the next years. The results indicate that ozone levels will exceed the established limits by national legislation within three years. The increase in ozone concentration occurs due to high emissions of reactive volatile organic compounds in an atmosphere with high levels of nitrogen oxides.

The influence of the context on behavioral and emotional reactions to a war crime situation military cadets (N = 315) is analyzed. The study is based on Milgram’s experience and the tragedy of My Lai.It examines personal and peer obedience to an anti-normative order (asking participants whether they would obey an order to shoot unarmed civilians) in five vignettes or scenarios that reproduce Milgram’s conditions and MyLai scenario. This is an experimental between-within study of five scenarios by two conditions (Milgram, 1974). Personal and collective obedience of other military, emotional reactions and values of Schwartz (2012) were measured. Showing enhancement of self-bias it is reported that the pairs would be more likely to shoot than one would. Replicating Milgrams’s results, obedience is greater when the order is given directly by an authority, and lower when there is conflict between authorities and peers rebel. Confirming that identification with humanity and not just with the in-group may prompt respondents to reject an anti-normative order, values of transcendence of the self are associated with less obedience and congruent emotional reactions. Self-perceived transformational leadership was associated with positive emotions towards peer that disobey to fire. However a transformational style perceived in the superior was associated to positive emotions by respect to soldier who open fire, adding information on the potential dark side of this leadership style. The relevance of personal values, leadership style and affectivity in military context is discussed.
