Breaking the Code of Silence: The Importance of Control Systems and Empathy Toward Outgroups

This study used data from 654 new officers attending several training academies in the United States to examine changes in recruits’ attitudes toward the code of silence. The results of multivariate multilevel growth models showed that recruits’ experiences at the academies strengthened their adherence to the code. The results also showed that shifts in officers’ attitudes about the community, seriousness of the misconduct, expected discipline, and familiarity with agency policies were directly associated with changes in their adherence to the code, but changes in job satisfaction and perceptions of organizational justice were not. Female officers exhibited less adherence to the code in incidents of physical violence compared with male officers. The results confirm the need for reform in police training. Specifically, academy leaders should ensure that instructors and training materials present positive images of the community as well as strengthen social control systems which reinforce the importance of reporting coworker’s misconduct.

Teaching Linear Control Systems: A Core Course in Electrical and Electronics Engineering

This paper presents the experience in teaching the course Linear Control Systems in Electrical and Electronics Engineering curriculum. This course is offered to third year engineering students. Students who pursue a degree in Electrical and Electronics Engineering are required to complete a laboratory course in the same semester. The motivation for offering this course is to make the students aware regarding the importance of control systems, controller design aspects and verification of designed systems through simulation. In order to have a system function as per the requirement, the understanding of control systems engineering is very essential. This paper presents the experience of teaching linear control systems course of an instructor for the first time with the incorporation of peer learning; Think - Pair - Share activity and personal mentoring of students. The students' performance scores of different tests are presented. Students' feedback is also included which clearly shows that the instructor has put efforts in doing justice in teaching this course.

Synthesis and implementation of procedural controllers for event‐driven operations

AbstractA framework is presented for synthesizing logic feedback controllers for event‐driven operations, which are used typically for startup and shutdown operations, emergency procedures, and alarm handling. The framework encompasses techniques for discrete‐event modeling of open‐loop process behavior and operational specifications, as well as the synthesis of feedback control mechanisms called procedural controllers. A procedural controller, if it exists, is mathematically guaranteed to satisfy its operational specifications. This is of particular importance for control systems in which high integrity and correctness are required by design (such as systems in which human life is at risk). The notions introduced and the framework presented are illustrated with a small example. The applicability of the framework to cases of industrial complexity is demonstrated by synthesizing a procedural controller and implementing it as a control code for a section of the operation of an automated multipurpose‐multiproduct batch pilot plant.

Control of a One-Dimensional Distributed Structure Based on Wave Propagation Analysis*

ABSTRACT Wave propagation in a one-dimensional structure is analyzed. Based on this wave propagation analysis, a control system for the structure is developed. The purpose of the control system is to improve the dynamic response of the structure to an external force. It is shown that the control system can completely isolate a section of the structure from disturbances caused by the external force, or it can add damping to the structure. The effects of two types of errors on the control system are considered. The example given here illustrates the potential importance of control systems based on wave propagation concepts and raises many issues that are involved in the development of such control systems.
