Findings demonstrated that overweight adolescents are more likely to be both victims and perpetrators of violent acts (Janssen et al., 2004). The present study tested this weight-based victimization/perpetrator hypothesis. The study sample comprised N1⁄4649 middle school students, which were regrouped in three weight categories (i.e. underweight, normal weight, overweight) according to the cut-offs proposed by the International Obesity Taskforce. In order to analyze group differences between the weight categories, three same sized groups (N 1⁄4 75) were randomly created from the whole data set. Results confirmed that overweight students are more likely to be victimized but not to become perpetrators themselves compared to their peers. Logistic regressions showed that being anxious (OR 1⁄4 2.34), having low self- esteem (OR1⁄40.58), having a higher BMI (OR1⁄41.11) and being male (OR1⁄40.26) are risk factors of victimization. Results will be discussed with respect to psychosocial interventions. [less ▲]

Voluntary Affiliation to Peru’s Individual Accounts Pension System

One important aspect in the design of social protection is coverage. In Peru, as in most Latin American countries, social security coverage is mandatory only for workers in the formal sector. This article investigates the determinants of voluntary affiliation to Peru’s individual accounts pension system. It is found that married males with more than high-school level education living in high income households and with other family members already affiliated to the individual accounts pension system have a higher likelihood of voluntary affiliation. Although the results suggest that family-based safety nets might be substitutes for voluntary participation in the individual accounts pension system, nonetheless, extending pension coverage and addressing poverty remain as challenges for government involvement.

Is the cerebral processing of categorical and coordinate spatial relations based on different or identical but differentially activated functional networks?

The fundamental hypothesis related to the distinction between categorical and coordinate processing has been that these two types of spatial relations coding are qualitatively different. Based on ... [more ▼]

The fundamental hypothesis related to the distinction between categorical and coordinate processing has been that these two types of spatial relations coding are qualitatively different. Based on Kosslyn’s initial hemispheric specialization theory, they also are hypothesized to rely on different functional networks in the brain which are supposed to have evolved in a way to take advantage of more fundamental hemispheric specializations in order to adapt these hemispheric strengths to the processing of the two different types of spatial relations.

This paper presents an implementa- tion of three Fuzzy Logic controllers working in parallel onboard a UAV, two for a pan-tilt camera platform and the third for control the yaw of the helicopter. This implementation uses a Lucas-Kanade tracker algo- rithm with a pyramidal optical ow implementation, which gives infor- mation to follow statics and moving objects, besides the UAV vibrations and movements. The platform con- troller is helped by the heading con- troller, in order to make smooth the big movements to the platform, re- ducing the risk of lost the warp selec- tion of the object to track. Also, the heading control remove the physic limit of the platform at the yaw axis. Some laboratory and UAV tests are presented in order to show the differ- ent behaviors and the good response of the presented controllers. [less ▲]
