In Brazil, the fall of the monarchy in 1889 by a military coup d'état led to the rise of the presidential system, headed by Deodoro da Fonseca. Aided by well-known jurist Ruy Barbosa, Fonseca established federalism in Brazil by decree, but this system of government would be confirmed by every Brazilian constitution since 1891, although some of them would distort some of the federalist principles. The 1937 Constitution, for example, granted the federal government the authority to appoint State Governors (called interventors) at will, thus centralizing power in the hands of President Getúlio Vargas. Brazil also uses the Fonseca system to regulate interstate trade. Brazil is one of the biggest federal governments.
What is the fonseca system?

The degree to which adolescents are perceived as autonomous beings varies widely by culture, as do the behaviors that represent this emerging autonomy. Psychologists have identified three main types of autonomy: emotional independence, behavioral autonomy, and cognitive autonomy. Emotional autonomy is defined in terms of an adolescent's relationships with others, and often includes the development of more mature emotional connections with adults and peers. Behavioral autonomy encompasses an adolescent's developing ability to regulate his or her own behavior, to act on personal decisions, and to self-govern. Cultural differences are especially visible in this category because it concerns issues of dating, social time with peers, and time-management decisions. Cognitive autonomy describes the capacity for an adolescent to partake in processes of independent reasoning and decision-making without excessive reliance on social validation. Converging influences from adolescent cognitive development, expanding social relationships, an increasingly adultlike appearance, and the acceptance of more rights and responsibilities enhance feelings of autonomy for adolescents. Proper development of autonomy has been tied to good mental health, high self-esteem, self-motivated tendencies, positive self-concepts, and self-initiating and regulating behaviors. Furthermore, it has been found that adolescents' mental health is best when their feelings about autonomy match closely with those of their parents.
Is an adolescent's mental health at its best when their feelings of autonomy match closely with their parents or when they are at odds?
match closely
