ENGR 482 Exam 2 Questions with Complete Solutions Graded A+

ENGR 482 Exam 2 Questions and Complete Solutions Graded A+ Engineering Definition of Risk AKA _______________________ - Answer: Probability Model of Risk Engineering Definition of Risk Formula - Answer: Risk=sum{(probability of event)(consequences)}^i Engineering Definition of Risk - Answer: Product of the likelihood of an event & the magnitude of the resulting harm When using Engineering definition of risk, one must be cautious not to _______________________________________________ - Answer: Quantitatively compare or add risk quantities that have different units 4 limitations to probabilistic definition of risk - Answer: Utilitarian Not risk averse Not probabilistic Cannot explain how risk is perceived by the public (car crash vs. nuclear meltdown) Utilitarian - Answer: Calculates magnitude of risk in terms of EXPECTED consequences. Limits of Utilitarianism - Answer: Cost/benefits distributed unjustly, expected outcome doesn't equal actual outcomes, permits us to do counterintuitive things. Limits of not risk averse - Answer: Does not tell you to avoid risk of a certain magnitude Limits of not being probabilistic - Answer: Can't assume the event in question has a known probability (never happened before) Conditions of _________ risk usually vary based on ______________ - Answer: Acceptable Perspective Engineers focus on the __________ issues of the probability & magnitude of harm and contains no _____________ evaluation of whether a risk is morally acceptable - Answer: factual implicit In order to determine whether a risk is acceptable, engineers and risk experts considering engineering solutions often use a ________________ that is fundamentally a _____________ approach. - Answer: cost-benefit analysis Utilitarian According to _____________, an acceptable risk is one in which the product of probability and magnitude of the harm is ____________ or ___________ by the product of probability and magnitude of the benefit. - Answer: Engineers Equaled Exceeded The engineering conditions of acceptable risk is very ____________ - Answer: Utilitarian Limitations to the acceptable risk model are ___________ to the limitations of the probabilistic model of risk - Answer: Closely related (both utilitarian) Limitations of acceptable risk model - Answer: Can't always anticipate all effects/consequences (cost-benefit analysis will be unreliable). Certain kinds of value don't seem measurable in monetary terms (human life). Makes no allowance for the distribution of costs/benefits (only considers net benefits). Gives no place for informed consent. Informed consent - Answer: Permission granted in the knowledge of the possible consequences, typically that which is given by a patient to a doctor for treatment with full knowledge of the possible risks and benefits. Layperson - Answer: A person without professional or specialized knowledge in a particular subject. Voluntary assumed risk - Answer: Risks which an individual knowingly takes on and accepts, as opposed to an uncertain risk involuntarily imposed on them. Free and Informed Consent and Equity and Justice - Answer: People tend to see risk as more acceptable when they freely consent to the risk, and are informed about it. Additionally, people tend to be willing to assume more risk when they are justly and equitably recompensed for it. Definition of acceptable risk from the "respect for persons" approach to ethics, which is more Kantian in nature: - Answer: "An Acceptable Risk is a risk that is freely assumed with informed consent or properly compensated..." (Harris et al) When imposing a risk on others, we are not permitted to treat them in a way they would not consent to, or rational people could not consent to. Perceived Risk AKA __________ - Answer: Subjective Risk Actual Risk AKA __________ - Answer: Objective Risk Perceived Risk - Answer: People perceive risk differently depending on how they perceive the risk to themselves (the likelihood that an event will happen to them) Actual Risk - Answer: The risk of an event actually happening at all Precautionary Principle - Answer: Where there are threats of serious or irreversible damage, lack of full scientific certainty shall not be used as a reason for postponing cost-effective measures to prevent environmental degradation. 4 dimensions of precautionary principle - Answer: If there is a THREAT, which is UNCERTAIN, then some kind of ACTION is MANDATORY. There is a ________ (pertaining to our knowledge) and __________ (pertaining to what we are required to do) element to the precautionary principle - Answer: Epistemic Normative Epistemic interpretation - Answer: In a precautionary appraisal of risk, it is more desirable to avoid false negative errors than false positive ones. In a precautionary appraisal of risk, it is more desirable to avoid false ___________ errors than false ___________ ones. - Answer: Negative Positive (Think cancer example, rather safe than sorry) False Positive Error - Answer: Type II False Alarm! You incorrectly think there is a correlation between some variables where none really exists. False Negative Error - Answer: Type I You fail to discover a correlation between some variables. In some sense, the ___________ interpretation of the precautionary principle is that you have to do something when there is an uncertain threat, and the ____________ interpretation says, "better safe than sorry." - Answer: Normative Epistemic Common limitations of fault & event tree analysis, especially inaccuracies that arise from __________ & _________ interactions - Answer: Tight coupling Complex (Often coincide) Tight Coupling Interactions - Answer: Temporal, meaning events happen too quickly for a response Complex Interactions - Answer: One event affects other systems or exacerbates other events in an unexpected way Technocratic Model - Answer: Holds that experts should be in charge of determining how we handle & manage risk (engineers call the shots) Democratic Model - Answer: Holds that all parties, even laypeople, should have a say in how we manage risk. Technocrat - Answer: Expert Downside to Democratic Model - Answer: Uninformed public perceives risk differently from engineers & in any case, we can be wrong about what is actually a risk Normalization of Deviance - Answer: The tendency to come to consider behavior that varies from good design/engineering practice as acceptable. Normalization of Deviance Example - Answer: Knowledge and Acceptance of "blow by" of hot gases during the launches of the space shuttle in the Challenger case. A "fix", not a redesign was always the remedy. Groupthink - Answer: The practice of thinking or making decisions as a group in a way that discourages creativity or individual responsibility 8 symptoms of groupthink - Answer: Invulnerability of group to failure A strong "we-feeling" Shift responsibility to others Assumes inherent morality of group Self-censorship to not "rock the boat" Illusion of unanimity, silence = consent Direct pressure on those who disagree Mindguarding, preventing outside views Proper Engineering Decision (PED) - Answer: A decision that should be made by engineers because it either involves technical matters that require engineering expertise OR falls within the ethical standards embodied in engineering codes (public health/safety) Proper Management Decision (PMD) - Answer: A decision that should be made by managers because it involves factors relating to the well-being of the organization, such as cost, scheduling, marketing, & employee morale/welfare AND the decision does not force engineers to make unacceptable compromises with their own technical and ethical standards. It is the __________ who should be involved when there is an ethical issue or morally relevant feature in a decision, and it is the _________ job not to interfere with that - Answer: Engineer Managers 3 kinds of ______________________ that engineers can employ when faced with an immoral decision - Answer: Organizational Disobediance Disobedience by contrary action - Answer: Engaging in activities contrary to the interests of the company, as perceived by management Disobedience by non participation - Answer: Refusing to carry out an assignment because of moral or professional objections Disobedience by protest - Answer: Actively and openly protesting a policy/action of an organization Whistleblowing - Answer: The most important kind of protest Internal Whistleblowing - Answer: This means that the whistleblower reports misconduct to another person within the organization.
