A game theory model of cybersecurity investments with information asymmetry

Abstract: In this paper, we develop a game theory model consisting of sellers and buyers with sellers competing non-cooperatively in order to maximize their expected profits by determining their optimal product transactions as well as cybersecurity investments. The buyers reflect their preferences through the demand price functions, which depend on the product demands and on the average level of security in the marketplace. We demonstrate that the governing equilibrium conditions of this model with security information asymmetry can be formulated as a variational inequality problem. We provide qualitative properties and propose an algorithmic scheme that is easy to implement. Three sets of numerical examples are presented which reveal the impacts of the addition of buyers and sellers and a variety of changes in demand price and investment cost functions on the equilibrium product transaction and security level patterns.

The 10-year Course of Adult Aggression toward Others in Patients with Borderline Personality Disorder and Axis II Comparison Subjects

Abstract: This study had two aims. The first was to assess and compare various types of aggressive behavior toward others reported by borderline patients and axis II comparison subjects over time. The second was to determine the best baseline and time-varying predictors of aggressive behavior in these borderline patients. At baseline, a series of interviews and self-report measures were administered to 290 borderline patients and 72 axis II comparison subjects. Measures assessing aggression toward others, axis I and II disorders as well as adult adversity were re-administered every two years over the course of ten years. It was found that borderline patients reported significantly higher rates of verbal, emotional, and physical aggression toward others than comparison subjects but the rates of these forms of aggression toward others declined significantly for those in both study groups. Multivariate analyses indicated that the strongest predictors of adult aggression towards others were severity of adult adversity and a substance use disorder. Taken together, these results suggest that borderline patients commonly report aggression toward others but that this aggression declines significantly over time. These results also suggest that this aggression toward others is most strongly associated with adult experiences of adversity and concurrent substance abuse.

The euphemism of good practice or advanced nursing practice

Abstract: Objective: To analyze how the focus given nowadays in our country to good practices in the care process as centrality of Nursing offers support to the discussion about the expansion of nurses' performance through advanced practices. Method: This is a theoretical-reflexive article, based on critical reading of studies on the subject, focused on the need to discuss the training of nurses in the perspective of their role expansion. Results: The arguments for both subjects, based on the discussion of the theoretical reference of the two themes: good practices or practice based on evidences, and advanced practice nursing. Final considerations and implications for practice: It is proposed that, in addition to good practices, undoubtedly necessary, the appropriation of advanced nursing practice and the debate about its adoption in the country are fundamental to the new professional challenges facing nursing and the training of human resources for the Unified Health System. The arguments presented lead to the knowledge of the nursing topic of recent dissemination in Brazil, the advanced nursing practice, which can substantially change the nurses' performance in our reality.
