  • Modern Control Theory and the Limits of Criminal Justice - Moving Control Theory Forward: Developing Control Theory and Creating Advantages Throughout Life
    Modern Control Theory and the Limits of Criminal Justice, 2019
    Co-Authors: Michael R Gottfredson, Travis Hirschi
    Abstract:

    Research on self Control from several disciplines demonstrates that relatively high levels of self Control, emerging from childhood, create considerable personal advantages that accumulate throughout life. This chapter summarizes Modern Control Theory and discusses directions for future development. It highlights the advantages of Control Theory, including disciplinary-free definitions of human nature and self Control and the focus on childhood socialization. The potential for advances in measurement and application is described. Contributions of the Theory to public policy are summarized. The role of higher levels of self Control for lifelong advantages and the benefits of prevention are described as expectations of the Theory worthy of considerable attention. The value of the Theory for macro and comparative criminology is discussed.

  • Modern Control Theory and the Limits of Criminal Justice
    2019
    Co-Authors: Michael R Gottfredson, Travis Hirschi
    Abstract:

    Modern Control Theory and the Limits of Criminal Justice updates and extends the authors’ classic general Theory of crime (sometimes referred to as “self-Control Theory”). In Part I, contemporary evidence about the Theory is summarized. Research from criminology, psychology, economics, education, and public health substantially supports the lifelong influence of self Control as a significant cause of problem behaviors, including delinquency and crime, substance abuse, school problems, many forms of accidents, employment instability, and many poor health outcomes. Contemporary evidence is supportive of the Theory’s focus on early socialization for creation of higher levels of self Control and other dimensions of the Theory, including the roles of self Control, age and the generality or versatility of problem behaviors, as well as the connections between self Control and later teen and adult problem behaviors. The book provides methodological assessments of research on the Theory, contrasting the Control Theory perspective with other developmental perspectives in criminology. The role of opportunity, the relationship between self and social Control Theory, and the role of motivation are addressed. In Part II, Control Theory is taken to be a valid Theory and is used to explore the role of criminal sanctions, especially policing and prisons, and policies about immigration, as methods to impact crime. Modern Control Theory provides an explanation for the general lack of effectiveness of formal, state sanctions on crime and instead provides substantial justification for prevention of delinquency and crime by a focus on childhood. The Theory effectively demonstrates the limits of criminal sanctions and the connection between higher levels of self Control and positive life-course outcomes.

  • Modern Control Theory and the Limits of Criminal Justice - General Theory, Public Policy, and the Limits of Criminal Justice
    Modern Control Theory and the Limits of Criminal Justice, 2019
    Co-Authors: Michael R Gottfredson, Travis Hirschi
    Abstract:

    In this chapter, the general Theory of crime depicted in self-Control Theory is taken as valid, and the implications for criminal justice are explored. The historical connections between classical Theory and criminal sanctions are described, and the relations between classical deterrence theories and Control Theory are examined. The classical Theory assumption that deterrence places limits of effectiveness on state sanctions is used in conjunction with the Modern notion of self Control. The result is that Modern Control Theory, supported by contemporary research on the effectiveness of criminal sanctions, explains why criminal sanctions have limited effectiveness for crime and sets limits on the appropriate use of criminal sanctions. Modern Control Theory, using classical school assumptions of human nature and choice, shows why public policy should focus on early socialization and prevention.

  • Modern Control Theory and the Limits of Criminal Justice - Prisons, Deterrence, and Incapacitation: A View from a Prevention Perspective
    Modern Control Theory and the Limits of Criminal Justice, 2019
    Co-Authors: Michael R Gottfredson, Travis Hirschi
    Abstract:

    Modern Control Theory doubts the effectiveness of criminal sanctions to affect the crime rate substantially. This view is contrasted with the expectations of the criminal career perspective, a leading view on the nature of crime and the role of the criminal justice system in Controlling crime by deterrence and incapacitation. The contrast is illustrated with differing expectations about how age is related to crime (including serious offending), the importance of the versatility effect for offending, and evidence about how changes in incarceration levels are expected to be related to crime rates. On all counts, the results of competent contemporary research support the expectations of the general Theory of crime over the expectations of criminal career/career criminal traditions. The research on statistical modeling and offender typologies in the criminal careers tradition has not provided consistent or replicated results demonstrating that criminal sanctions effectively incapacitate or deter offending. Control Theory is inconsistent with mass incarceration, with the belief that increasing severity of sanctions reduces crime rates either by incapacitation or by deterrence, and notes that crime tends overwhelmingly to decline with age for all offenders beginning in early adulthood.

  • real time active flow Control based on Modern Control Theory
    29th AIAA Fluid Dynamics Conference, 1998
    Co-Authors: Yutaka Ikeda
    Abstract:

    A method for Controlling fluid flow in real-time is discussed. The approach taken here for designing a Controller is based on Modern Control Theory. Modern Control Theory can provide a powerful tool for designing a Controller. It provides a way not only to design a Controller but also to design an optimal one if the system model is known. Hence, the system modeling plays a key role. In this paper, the system consists of a fluid flow to be Controlled, and is modeled based on input-output relationship of the system rather than equations based on flow physics, since the latter requires computationally too intense and timeconsuming algorithms for real-time Control. The specific Modern Controller design technique used in this paper is Linear Quadratic Gaussian (LQG). To demonstrate the schemes of the system modeling and Control, an application to downstream temperature Control of a jet is also discussed.

  • The practice of MATLAB simulation in Modern Control Theory course teaching
    2012 IEEE Fifth International Conference on Advanced Computational Intelligence (ICACI), 2012
    Co-Authors: Lina Liu, Jian Hu
    Abstract:

    Modern Control Theory is one of the basic professional course for the senior undergraduates, such as automation, electrical engineering and automation specialties. It has the characteristics of higher theoretical definition and abstraction, bigger calculated amount, degree of depth and complexity, and the students should have well-knit mathematical foundation. The study can be made more interesting and challenging by introducing the simulation technology into course teaching. By applying MATLAB language and Simulink simulation tools, combining with the teaching examples, the system synthesis design problem in Modern Control Theory course can be dealt with very easy. A closed-loop Control system with full-order state observer is designed. The design process shows that fundamental changes in Modern Control Theory course teaching have been made by MATLAB language and Simulink tools. The teaching process is converged to the combination of practical engineering case and vivid teaching from original dry pure Theory teaching.
