Emotional characteristics of psychology students: a study based on the formative research perspective

In the formative research scheme, the author built a psychological scale, with the purpose of analyzing psychological characteristics of the School of Psychology students. The instrument showed a high reliability coefficient (α=0,86), the exploratory factorial analysis found five variables which allowed to predict some aspects of sex and career level through a logistic regression; the ALSCAL showed two emotional dimensions. The author recommends to improve the instrument and to continue its application in the School. It is also necessary to develop qualitative research to acquire new data about the topic of the research.

Familiar characteristics and received familiar support among Brazilian adolescents with and without pregnancy experience

The present paper aimed to investigate how adolescents with pregnancy experience evaluate received support from their families in comparison with an adolescent group without pregnancy experience. 452 low income adolescents, both sex, aged 14 to 19 years old answered to a questionnaire. The results revealed that more girls (64.2 %) than boys (35.8 %) declared pregnancy experience, ?2 (2, n = 2617) = 48.32, p < .001. Moreover, it was observed that the group with pregnancy experience, in comparison with other group, revealed more perception on the family relationships safety, t (408) = -3.0, p < .01; mutual respect among family members in their homes, t (392) = -2.3, p < .05; and received stronger general support from their family, t (397) = -1,3, p < .05. These results are discussed.

Informal housing in the XXI century. Characteristics of the informal land and housing supply in Bogota during the first decade of the XXI century

This article characterizes the conditions of the informal land and housing supply during the first decade of the xxi century in Bogota, regarding magnitude and location of the informal urban growth (new occupations in the periphery and informal densification of consolidated areas), housing  conditions in recent occupations and the characteristics of the land market. The situation of the  last decade has been reconstructed based in aerial photography analysis, census data quantification  and data analysis from planning and control public entities. Results suggest that due to the relative  land scarcity in Bogotá, among other aspects, the informal market dynamics have experimented changes compared to previous decades, because the growth in consolidated urban areas becomes  more important than the informal urbanization of the peripheries, but at the same time informality  transcends the municipal perimeter to the neighboring municipalities.

Neighborhood characteristics and the spatial concentration of crime: Evidence for Bogotá

Using a unique neighborhood crime dataset for Bogotá in 2011, this study uses a spatial econometric approach and examines the role of socioeconomic and agglomeration variables in explaining the variance of crime. It uses two different types of crime, violent crime represented in homicides and property crime represented in residential burglaries. These two types of crime are then measured in non-standard crime statistics that are created as the area incidence for each crime in the neighborhood. The existence of crime hotspots in Bogotá has been shown in most of the literature, and using these non-standard crime statistics at this neighborhood level some hotspots arise again, thus validating the use of a spatial approach for these new crime statistics. The final specification includes socioeconomic, agglomeration, land-use and visual aspect variables that are then included in a SARAR model an estimated by the procedure devised by Kelejian and Prucha (2009). The resulting coefficients and marginal effects show the relevance of these crime hotspots which is similar with most previous studies. However, socioeconomic variables are significant and show the importance of age, and education. Agglomeration variables are significant and thus more densely populated areas are correlated with more crime. Interestingly, both types of crimes do not have the same significant covariates. Education and young male population have a different sign for homicide and residential burglaries. Inequality matters for homicides while higher real estate valuation matters for residential burglaries. Finally, density impacts positively both crimes.
