We analysed the influence of wildfire area, topography, fuel, surface weather and upper-level weather conditions on long-distance spotting during wildfires. The analysis was based on a large dataset of 338 observations, from aircraft-acquired optical line scans, of spotting wildfires in south-east Australia between 2002 and 2018. Source fire area (a measure of fire activity) was the most important predictor of maximum spotting distance and the number of long-distance spot fires produced (i.e. >500m from a source fire). Weather (surface and upper-level), vegetation and topographic variables had important secondary effects. Spotting distance and number of long-distance spot fires increased strongly with increasing source fire area, particularly under strong winds and in areas containing dense forest and steep slopes. General vegetation descriptors better predicted spotting compared with bark hazard and presence variables, suggesting systems that measure and map bark spotting potential need improvement. The results from this study have important implications for the development of predictive spotting and wildfire behaviour models.

This paper describes neonatal intensive care units (NICU) in Italy using a set of organizational variables identifying management profile. The correlations between variables, and how these are impacted by structural aspects of the department or hospital, are investigated. The research was conducted within the 5-year far-reaching and complex SONAR study run by the Italian Neonatal Network, which maps NICU, monitors outcomes of member centres, defines organizational models, and identifies best practices to improve care quality. Seven variables relating to activities, organization processes, and behaviour models used in the SONAR study were used here to assess NICU. Data from 54 Italian NICUs, 1601 nursing staff, and 643 doctors were used. We identified high levels of variation in NICUs for all aspects of organization. We also identified important opportunities for improvement, especially in the areas of performance measurement, quality improvement, and learning for healthcare staff. In terms of structural characteristics, we identified big differences between NICUs in the north and south of Italy. The findings provide a description of NICUs in Italy and identify a set of variables useful for management in assessing NICU, which are among the most complex and costly operational units in a hospital.

Purpose The purpose of this paper is to investigate the relationship of values with individual economic behaviour, identifies the correlation between personality values that are conditioned upon the culture, and evaluations of economic behaviour situations on the example of Russian culture. Design/methodology/approach This study involved 222 people of Russian nationality, young entrepreneurs employed in the commercial field, developing their own business. The following methods were used in the study: the methodology for measuring the values of an individual and cultural level; Melbourne Decision Making Questionnaire, a scenario methodology for economic behaviour, which is a short behavioural scenario (model of behaviour), taken from real life. The statistical processing of experimental data was carried out using the IBM SPSS Statistics Version 21 software package. Findings The values with correlated progressive and regressive economic forms of behaviour were identified for modern Russian society. The correlation of factors with progressive and regressive economic behaviour was also identified. Practical implications The practical significance of the study lies in the possibility of applying the results obtained not only in the system of economic education but also in programs to support the business activity of young entrepreneurs. Originality/value The value of this study is determined by the fact that it can be placed in a broader context of research into the relationship between the levels of human consciousness and his behaviour.

Movies are one of the objects of study for Social Psychology because they are not only art or industry; they are a way of socialization. Therefore, movies show behaviour models, social values and norms, and make people react: movies are persuasive. A psycho-social analysis of films is necessary because movies can sometimes display prejudiced negative contents, which could be both explicit or very subtle, and therefore quite dangerous. The authors analyse ten well-known Dis-ney films from the gender perspective: How are men and women shown? What roles do they impersonate? Specifying contents and valuing subtle prejudiced stereotypes will help families to watch them from a different point of view. El cine es objeto de estudio para la Psicología Social porque no sólo es arte o industria; es socialización. Porque muestra modelos de comportamiento, valores sociales y normas, produce reacciones: es persuasivo. Este aspecto es el que mejor justifica el análisis psicosocial. También en muchas ocasiones, el cine presenta unos contenidos con prejuicios negativos poco explícitos, muy sutiles y, por tanto, bastantes peligrosos. Analizamos diez conocidas películas Disney desde la perspectiva de género: ¿Cómo se presentan hombres y mujeres? ¿Qué roles representan? Explicitar contenidos y valorar estereotipos con prejuicios sutiles ayuda a las familias a ver con otra mirada.
