    Influence of intrafamilial abuse in children's change of values towards their parents

    The socialization that parents and society exercise on children instills in them a set of values towards parents. Some of these values are not lying, feeling affection for the parents, and wanting to have contact with them. In this work, we attempt to determine whether these values change in the face of intrafamilial abuse. To that end, an incidental sample was used, consisting of 2730 minors aged between 6 to 18 years, who had never suffered abuse. They were asked to put themselves in the place of the main character of a story. The story varied depending on the conditions to be studied: observation and direct suffering or account of the abuse by another, type of abuse (physical or psychological), who perpetrated the abuse (custodian or non-custodial), and who received it (the other custodian or the minor). The results show that, as a rule, children lie to conceal both parents' abusive behavior; they love their parents and want to have contact with them, even in the presence of abuse. Notwithstanding that in the presence of abuse by one of their parents, children still love them and want to have contact with both parents, a significant number of children, however, stop loving them or want to have contact with the abusive parent. These results undermine what is defended by theories like PAS with no scientific evidence, and underline the need to use scientific procedures to test the reliability of minors’ testimony based on the idea that children tell the truth.Die von Eltern und Gesellschaft initiierten Sozialisationsprozesse erziehen Kindern eine Reihe von Werten im Umgang mit ihren Eltern an. Einige dieser Werte sind beispielsweise: nicht zu lügen, eine Zuneigung zu den Eltern zu verspüren und Kontakt zu ihnen haben zu wollen. In dieser wissenschaftlichen Arbeit wird versucht zu untersuchen, ob sich diese Werte bei innerfamilialem Missbrauch verändern. Zu diesem Zweck wurde eine Stichprobe von 2730 Minderjährigen im Alter zwischen 6 und 18 Jahren, die noch nie missbraucht wurden, herangezogen. Sie wurden gebeten, sich in die Hauptfigur einer Geschichte hineinzuversetzen. Die Geschichte variierte je nach den zu untersuchenden Bedingungen: Beobachtung und direktes Erleiden oder Erzählung des Missbrauchs durch andere, Art des Missbrauchs (physisch oder psychisch), wer den Missbrauch begangen hat (erziehungsberechtigter oder nicht erziehungsberechtigter Elternteil) und wer dem Missbrauch ausgesetzt war (der andere Elternteil oder das Kind). Die Ergebnisse zeigen, dass Kinder in der Regel lügen, wenn es darum geht das missbräuchliche Verhalten von einem der beiden Elternteile zu verbergen. Sie lieben ihre Eltern und möchten Kontakt zu ihnen haben, selbst im Falle von Missbrauch. Ungeachtet dessen, das einige Kinder bei Misshandlung durch einen ihrer Elternteile, beide Eltern immer noch lieben und Kontakt zu ihnen haben wollen, hört eine signifikante Anzahl von Kinder auf, den missbrauchenden Elternteil zu lieben oder Kontakt zu ihm haben zu wollen. Diese Ergebnisse falsifizieren, was von Theorien wie PAS ohne wissenschaftliche Beweise behauptet wird und unterstreichen die Notwendigkeit der Verwendung wissenschaftlicher Verfahren, die auf der Idee fußen, dass Kinder die Wahrheit sagen, zur zuverlässigen Untersuchung der Zeugenaussagen von Kindern

    Systems-theoretic Safety Assessment of Robotic Telesurgical Systems

    Robotic telesurgical systems are one of the most complex medical cyber-physical systems on the market, and have been used in over 1.75 million procedures during the last decade. Despite significant improvements in design of robotic surgical systems through the years, there have been ongoing occurrences of safety incidents during procedures that negatively impact patients. This paper presents an approach for systems-theoretic safety assessment of robotic telesurgical systems using software-implemented fault-injection. We used a systemstheoretic hazard analysis technique (STPA) to identify the potential safety hazard scenarios and their contributing causes in RAVEN II robot, an open-source robotic surgical platform. We integrated the robot control software with a softwareimplemented fault-injection engine which measures the resilience of the system to the identified safety hazard scenarios by automatically inserting faults into different parts of the robot control software. Representative hazard scenarios from real robotic surgery incidents reported to the U.S. Food and Drug Administration (FDA) MAUDE database were used to demonstrate the feasibility of the proposed approach for safety-based design of robotic telesurgical systems.Comment: Revise based on reviewers feedback.

    Reliability Analysis for the Advanced Electric Power Grid: From Cyber Control and Communication to Physical Manifestations of Failure

    Get PDF
    The advanced electric power grid is a cyber-physical system comprised of physical components, such as transmission lines and generators, and a network of embedded systems deployed for their cyber control. The objective of this paper is to qualitatively and quantitatively analyze the reliability of this cyber-physical system. The original contribution of the approach lies in the scope of failures analyzed, which crosses the cyber-physical boundary by investigating physical manifestations of failures in cyber control. As an example of power electronics deployed to enhance and control the operation of the grid, we study Flexible AC Transmission System (FACTS) devices, which are used to alter the flow of power on specific transmission lines. Through prudent fault injection, we enumerate the failure modes of FACTS devices, as triggered by their embedded software, and evaluate their effect on the reliability of the device and the reliability of the power grid on which they are deployed. The IEEE118 bus system is used as our case study, where the physical infrastructure is supplemented with seven FACTS devices to prevent the occurrence of four previously documented potential cascading failures

    Studying the effects of intermittent faults on a microcontroller

    As CMOS technology scales to the nanometer range, designers have to deal with a growing number and variety of fault types. Particularly, intermittent faults are expected to be an important issue in modern VLSI circuits. The complexity of manufacturing processes, producing residues and parameter variations, together with special aging mechanisms, may increase the presence of such faults. This work presents a case study of the impact of intermittent faults on the behavior of a commercial microcontroller. In order to carry out an exhaustive reliability assessment, the methodology used lies in VHDL-based fault injection technique. In this way, a set of intermittent fault models at logic and register transfer abstraction levels have been generated and injected in the VHDL model of the system. From the simulation traces, the occurrences of failures and latent errors have been logged. The impact of intermittent faults has been also compared to that got when injecting transient and permanent faults. Finally, some injection experiments have been reproduced in a RISC microprocessor and compared with those of the microcontroller. © 2012 Elsevier Ltd.
