The purpose of this paper is to study the adoption of Social Networking Services (SNS) by members of generation Y. The paper shows an empirical validation of a theoretical model that explains the use of SNS as a result of individual antecedents that affect the perception of its usefulness. The result of the fieldwork with a sample of 771 SNS users was analyzed in a structural equation model based on PLS (Partial Least Squares). The analysis of this data supports the theoretical model that explains the use of SNS in terms of perceived ease of use and perceived usefulness. Additionally, the model explains that the perception of usefulness is due to the perception of the degree of social identity, altruism, and telepresence. [ABSTRACT FROM AUTHOR]

In recent years, Latin America has become one of the most violent regions of the world (UNODC, 2014). Increasing crime is constant, and according to the United Nations Development Program (2013) public security policies to reverse this trend are urgent. This article examines the prevalence of crime during the period 2001-2013 in Bolivia, one of the continent's poorest countries and with the highest percentage of indigenous population. In the context of constitutional changes that recognize forms of community justice, this article also discusses the scope of the citizen security reforms proposed by the State in recent years and the responses of civil society to a growing sense of insecurity. At the same time this paper offers suggestions for public policies that incorporate broader structural changes than just police modernization and fighting against crime. Despite efforts to prevent crime and build more trust in the population, the state is overcome by informal dispute resolution practices that challenge its own power. [ABSTRACT FROM AUTHOR]
