Transcript: The Dark Tetrad Regression analysis showed that direct sadism uniquely predicted cyber-trolling on YouTube and other forum sites. Direct Sadism β = .44 Direct Sadism r = .40* Permanence Target mass audience Anonymity Time Convenience What about Cyber-Trolls? What is “trolling”? Study 2: Does Sadism Map Onto Core Characteristics of Cyber-Trolls? Psychopathy They are impulsive thrill seekers Narcissism They are egotistical and self-centered Machiavellianism They are strategic manipulators Sadism Seek opportunities to hurt people Direct vs. vicarious sadism A Psychological Study Direct Sadism β = .56*** Trolling Thanks for listening! Conclusion Cyber-Trolls: Just harmless pranksters? Cyber-Activities and the Law Study 1 Just Harmless Pranksters? Multiple regression analysis showed a strong, unique relationship between direct sadism and trolling. Machiavel -lianism Study 1 Someone who intentionally posts inflammatory material on the internet Someone who posts inappropriate remarks for their own amusement The elicited reactions reinforce cyber-trolling and nefarious amusement Dark tetrad personalities reported greater enjoyment of cyber-stalking on Facebook than others Narcissism r = .46** What are the personality and internet activities of cyber-trolls? No previous studies There are 4 suspects: Dark Tetrad (psychopathy, narcissism, Machiavellianism, sadism) Future Research Narcissism β = -.11* β = .44, SE = 0.68, t(100) = 2.05, p = .05 Cyber-Trolls β = .03 Cyber-bullying is defined as: “… a type of harassment using new technology. Whether it is criminal harassment depends on the facts of a case. Cyberbullies use social media (such as Facebook, Twitter, and YouTube), blogs, texting, instant messaging, and other internet avenues to engage in deliberate, repeated, and hostile behaviour intended to harm, embarrass, or slander someone. Although their work is public, cyberbullies are often anonymous and it is often harder to identify and stop them.” Cyber-bullying may also be defamation The Criminal Code (section 300) outlaws publishing a defamatory libel – material published, without lawful justification or excuse, likely to injure the reputation of any person by exposing them to hatred, contempt or ridicule, or designed to insult the person. Study 2: Are Cyber-Trolls Sadists? Cyber-Trolls: Who are they? Cyber-Trolls: Also Cyber-Bullies? Vicarious Sadism r = .33* Cyber-Activities and the Law Cyber-Trolls: Characteristics There is no specific legislation for cyber-bullying or cyber-trolling Civil Law Defamation: slander or libel Unsafe environment Responsibility for any consequences that perpetrator might reasonably have guessed would happen Criminal Law Harassment Defamatory libel Anywhere on the internet! Internet forums Imageboard, social news or entertainment sites (e.g., 4Chan, Reddit, 9Gag) Comment sections of various websites (e.g., news outlets) Social media websites (e.g., Facebook, Youtube) There is no specific legislation for cyber-bullying or cyber-trolling Civil Law Defamation: slander or libel Unsafe environment Responsibility for any consequences that perpetrator might reasonably have guessed would happen Criminal Law Harassment Defamatory libel Cyber-Trolls: A Psychology Study Cyber-Trolling and Bullying Facilitated by Technology Legal Implications: The Debate Cyber-Trolls: Also Cyber-Bullies? Results Study 1: Dark Personalities and Social Media Usage Trolling scale items: “I have sent people to shock websites for the lulz.” “I like to troll people in forums or the comments section of websites.” “The more beautiful and pure a thing is, the more satisfying it is to corrupt it.” The End Gaming Griefers Grief tourists Cyber-Trolls: Also Cyber-Bullies? Judith Donald (1996) Someone who engages in identity deception and manipulation Whitney Phillip’s (2012) Four Pillar Theory of Trolls Self-identify as trolls Vernacular language (e.g., plox, sauce, lulz) Trolling for the “lulz” (troll reward, troll food) Anonymity Vicarious Sadism Big Issues β = .19** Criminalize cyber-bullying or Educational Campaigns against Bullying Trolling is motivated by sadistic pleasure-seeking This may have important legal implications, especially in cases of extreme harassment with tragic outcomes Trolling indicates broader anti-sociality Technology has facilitated the damage that Dark Personalities can do Permanent damage Narcissists, direct sadists and vicarious sadists expressed greater enjoyment of cyber-trolling on YouTube than others. Cyber-Trolls: Where are they? Psychopathy β = .06 But there are other types of cyber-trolls… The case of Amanda Todd

A fault tree analysis (FTA) is a deductive failure analysis method that models the pathways within a system that can lead to failures or undesired results. It is a top-down method which starts at a single point and then branches out downwards to display different states of the system using logic symbols. A fault tree analysis (FTA) is a deductive failure analysis method that models the pathways within a system that can lead to failures or undesired results. It is a top-down method which starts at a single point and then branches out downwards to display different states of the system using logic symbols. Benefits of Fault Trees Benefits of Fault Trees A fault tree creates a visual record of a system that shows the logical relationships between events and causes lead that lead to failure. It helps others quickly understand the results of your analysis and pinpoint weaknesses in the design and identify errors. How FTAs are Used How FTAs are Used Fault tree analysis is useful in engineering, especially in industries where failure can have huge consequences such as nuclear power or aeronautics. However, fault tree analysis can also be used during software development to debug complex systems. How to Make a Fault Tree: Steps to Fault Tree Analysis How to Make a Fault Tree: Steps to Fault Tree Analysis Define the undesired event: the primary fault or failure being analyzed Deduce the event's immediate causes Keep stepping back through events until the most basic causes are identified Construct a fault tree diagram Evaluate your fault tree analysis

Fault Tree Analysis

Transcript: Postulate top event (fault) Branch down listing faults in the system that must occur for the top event to occur Consider sequential and parallel or combinations of faults Use Boolean algebra to quantify fault tree with event probabilities Determine probability of top event Terms FTA is a deductive analysis approach for resolving an undesired event into its causes. Logic diagrams and Boolean Algebra are used to identify the cause of the top event. Fault tree is the logical model of the relationship of the undesired event to more basic events. The top event of the Fault tree is the undesired event. The middle events are intermediate events and the basic events are at the bottom. The logic relationship of events are shown by logic symbols or gates. It is concluded that mechanical systems/subsystems connected like condenser tube jammed and lube oil tank leak are found to be attributing to the plant unavailability. These components are the major contributing factors compared to the failure of other electrical systems and subsystems. For optimization of plant availability, it is observed that the quality of water and steam filters with proper valve regulation would remain very effective besides regular implementation of maintenance features. Effective maintainability measures, such as preventive and periodic maintenance, have to be practiced and monitored to optimize the plant performance. With regard to the electrical systems/subsystems, malfunctioning of the breaker and operating mechanism have contributed to the unavailability of power. This could be averted by periodic calibration of control and protective electrical systems. It is noted that availability features like an effective inventory level would reduce the long downtime. Optimizing the power output from the co-generation power plant would extend value addition for the entire mill and, hence, from the fault tree analysis, it is concluded that the effective maintenance techniques and availability features so recommended are implemented from time to time and reviewed periodically. Such an effort would derive tangible benefits and establish the commercial viability of incorporation of a co-generation power plant in any continuous process industries. Normally, the effectiveness or reliability of such co-generation power plants can be optimized based on meticulous planning and implementing of maintainability and availability features.
