This paper suggests a framework for thinking about the prevention of youth violence. The decision on which crime prevention measures should be undertaken starts with an analysis of whether the measure is not only effective, but is the most cost effective approach that is plausible under the circumstances. The next decision is equally difficult: should the intervention be focused on the immediate location in which the problem is occurring, or should the focus be on the youth, the community, the family, or the school, all of which can affect the likelihood that youths will offend. These are difficult choices. It is important, therefore, to know what the consequences are of those approaches that are chosen. It is equally important to consider the consequences of not choosing other approaches

This article is an attempt to grasp the meaning of a warlike habitus buildup found within the ranks of the Colombian guerilla movement called FARC-EP. The author approaches the dynamics of the lives of men and women following an emotional framework that shape up that organization. The goal is to determine the incidence of a coercive drive found not only between individuals but also rival groups, with its system of rules and ideological principles of a revolutionary nature, in order to determine distinctive forms that the guerillas have developed to deal with their feelings.

The author hold as their starting point the principle that violence is associated with violation of order, and they analyze the codes of mutual exchange found in group behavior. The authors exam the libertarianpolitical environment that carry youngsters to violence by means of illegal practices, having as reference the role of Corsica’s National Liberation Front. They hold that the theoretical stimulating challenge to be found within an active sociology consists in one understanding the logic of organized action in a complex web of meaningful relationships that will thus rearticulate both individual experience and society.

In this paper, we derive uniqueness conditions for a constrained version of the Parallel Factor (Parafac) decomposition, also known as Canonical decomposition (Candecomp). Candecomp/Parafac (CP) decomposes a three-way array into a prespeci ed number of outer product arrays. The constraint is that some vectors forming the outer product arrays are linearly dependent according to a prespeci ed pattern. This is known as the PARALIND family of models. An important subclass is where some vectors forming the outer product arrays are repeated according to a prespeci ed pattern. These are known as CONFAC decompositions. We discuss the relation between PARALIND, CONFAC and the three-way decompositions CP, Tucker3, and the decomposition in block terms. We provide both essential uniqueness conditions and partial uniqueness conditions for PARALIND and CONFAC, and discuss the relation with uniqueness of constrained Tucker3 models and the block decomposition in rank-(L; L; 1) terms. Our results are demonstrated by means of examples.

We study the dynamical behavior of systems constituted of two coupled magnetic lms. We consider that the coupling of the lms can be represented by an interaction like Heisenberg to have the magnetic susceptibility of each medium, taking into account the presence of interface e ect and the neighboring layer. Through the calculation of the magnetization of the system, we found an expression for the susceptibility of the coupled system, which can be understood as a weighed mean of the susceptibility of the media that compose the system. Our results can be used to have the dynamic behavior of any magnetic bilayer. We use the result to calculate the dispersion relation of polaritons propagating in a magnetic bilayer consisting of an antiferromagnetic layer grown in direct contact with a ferromagnetic lm. Numerical results were obtained for a system where the antiferromagnetic material is MnF2 and the ferromagnetic is Fe. The results of the dispersion relation are con rmed through the calculation of the re ectivity of a Attenuated Total Re exion (ATR) experiment.

The objective of this study is to verifity what factor (index of economic growth or index of income inequality) the best index of the poverty in the Ceará States. For this, it was used given of secular series of Headcount (Po), Gini Index and per capita average income who understand the period of 1981 the 2007, beyond the ordinary least squares (OLS) for the esteem of the elasticities, the model of autoregressive vectors (VAR) and of the variance decomposition analysis. The results showed that in relation to the elasticities how much in the analysis of variance decomposition that the poverty in the Northeast Region is explained by the proper poverty in the states, but the inequality of income in these states also influences this existing poverty in the region. This implies that combat politics the income inequality are more efficient in the reduction of the poverty of what politics of increase of the income.

Spin waves are collective excitations that occur in magnetic materials. In the ferromagnetic case, these collective excitations are the motion in phase of the spin precession in a magnetic crystal lattice, representing a magnetic crystal. This precession is caused by disturbances in the magnetic system under study, for example, a small change in temperature causes variation in the number of precessions system. This variation in temperature causes the precession of a magnetic dipole moment of which interacts with its neighbors, leading to a spread of the disturbance. This disturbance has wave character, and the same intensity for different neighbors next. These waves of spin can be observed by some experimental methods, such as: the inelastic neutron scattering, inelastic scattering of light including Raman and Brillouin scattering, to name a few. The importance of spin waves emerges clearly when magnetoelectronic devices are operated at high frequencies. This situation, the generation of spin waves can sing in a significant loss of energy of these systems, because the excitation of such waves consumes a small part of the energy of the system. Therefore, the generation of spin wave limits the width of line and the power factor, or quality, Q, of some microwave devices. Due to the application technologic, is major study spin waves in magnetics multilayer systems and systems of low dimensionality, because these systems are candidates for obtaining new electronic systems. Our goal here is to study the behavior of the spin waves in two-dimensional systems where the exchange interactions are random. Random exchange interactions imply that the resistance that the system requires changing the orientation of their magnetic dipole moments of are not the same line by line in the environment under study. The system is model by Heisenberg Hamiltonian where the spin operators are treated at low temperatures using the transformations of Holstein-Primakoff. We observed that the spectrum of spin waves changes significantly when compared to that without the random disturbance.

Low educational levels, high taxes of students that drop out of school or fail to succeed, and difficulties to get the first job constrain Portugal to a particularly unfavorable stand when one contrasts those data to other countries’ that are our partners in the European Union. Causes are many and have been amply discussed, and it known today that they are not a sole outcome from shortcomings of institutions that are entrusted with the development of youngsters such as schools, community, hiring businesses or promoters of leisure activities, but rather all of them together. With this intervention one seeks to address some issues considering the agent behind educational processes, specifically those issues related to the environment where they are engendered.

The article evaluates racial and non-racial interpretations related to Portuguese national identity in the twenty century, considering their intersections with official state nationalism. The article is based on the work of four intellectuals, both Portuguese and Brazilian, who exerted a major influence on representations about Portuguese national identity: Mendes Correia, Gilberto Freyre, Sérgio Buarque de Hollanda and Jorge Dias. Investigations about these works highlight relations, affinities and confrontation between texts and their authors, revealing not only changes seen within the intellectual field, but also developments in the definition of official nationalism. The analysis buildup took into consideration not only the context for production of the works but also their distinctive forms of receptivity.

The objective of this study is to analyze the competitiveness of Brazilian exports of fish in the United States market from 2000 to 2008. To identify the products with revealed comparative advantage, and analyze the quality of expertise were used indicators of Revealed Comparative Advantage (RCA), Sales Performance (SP) and Quality of expertise (QE). The results showed that the Brazilian fishing industry is in a great competitive situation in the U.S. market. The products in a state of withdrawal, and with missed opportunities (live fish and fish fillets) represent important business opportunities and investments in trade between Brazil and the United States.

The determination of economic values on the environment, in particular landscapes and other touristic environmental sites, which constitute reason for public visitation is crucial for the sustainable development of the tourism. Therefore, this study aims at briefly describing the environmental values and to point out the ways in which those values may be used for the conservation of environmental resources that are exploited as touristic activity. It may be concluded that the economic valuation of environmental goods is of fundamental importance for the accurate elaboration of planning, as well as the carrying out of touristic projects. Furthermore, it is fundamental for providing subsidies for the agencies responsible for the elaboration and implementation of politics aimin gat the conservation of such resources, particularly for the estimation of fees and other types of punishment for hazards caused to environmental resources.
