A researcher conducting behavioral research collects individually identifiable sensitive information about illicit drug use and other illegal behaviors by surveying college students. One of the subjects is in an automobile accident two weeks after participating in the research study. Is this an example of an unanticipated problem that requires reporting to the IRB?


Yes, this must be reported because it was not listed as a risk of study participation in the consent form (was unexpected) and the subject experienced harm.


Yes, this must be reported because it involved a subject in a research study and it's up to the IRB to determine if it was related to participation.


No, this does not need to be reported because it was assessed by the researcher as unrelated to the research study.


No, this does not need to be reported to the IRB since the researcher reported it to the sponsor of the study.


Answer: No, this does not need to be reported because it was assessed by the researcher as unrelated to the research study.

A researcher conducting behavioral research collects individually identifiable sensitive information about illicit drug use and other illegal behaviors by surveying college students. The data are stored on a laptop computer without encryption, and the laptop computer is stolen from the researcher's car on the way home from work. This is an unanticipated problem that must be reported because the incident was (a) unexpected (i.e., the researchers did not anticipate the theft); (b) related to participation in the research; and (c) placed the subjects at a greater risk of psychological and social harm from the breach in confidentiality of the study data than was previously known or recognized. According to OHRP, this unanticipated problem must be reported to the IRB in which timeframe?

A study that involves interviews of adults is eligible for expedited review. The researcher wants to add an adolescent population (aged 12 to 17) to the study and has designed a parental permission and assent process. No additional changes are planned. Which of the following statements about review of the revised protocol is accurate?


The research would only be eligible for expedited review if the adolescents are capable of understanding the same consent forms used for the adult population.


The research would only be eligible for expedited review if the adolescents have been declared to be emancipated minors.


The new research would need full review by a convened IRB because children are a protected population.


Unless the nature of the questions would raise the level of risk to more than minimal for adolescents, the research would still qualify for expedited review.

A researcher's study uses a dataset of prisoner demographic characteristics. This dataset includes criminal history data that predates incarceration and includes data on disciplinary behavior while in prison. There is no interaction with prisoners. The researcher claims and the IRB chair agrees that the study is exempt from IRB review. This decision:


Is wrong since the chair is the only person who can determine that a study is exempt from further review. It is not the researcher's call.


Is correct if the IRB chair is also the prisoner representative for the Board.


Is correct since the lack of direct interaction removes the concern of undue influence that might occur with contact with prisoners.


Is wrong. 45 CFR 46.101(b) states that research conducted in prisons may not be exempt.


Answer: Is wrong. 45 CFR 46.101(b) states that research conducted in prisons may not be exempt.

A sociologist wants to study a culture that occurs in some women's prisons: "state families," in which individual prisoners take on certain roles within a group of like-minded prisoners. There is previous evidence that younger prisoners will use older inmates who play the roles of grandparents as a resource before they will turn to staff for help and advice. The lieutenant in charge of a dorm of long-term prisoners offers to gather volunteers to speak to the researcher and also offers to vouch for the integrity of the researcher. The use of this staff is:

True or false? The evolution of different ecomorphs on the Caribbean islands is an example of stabilizing selection.

True or false? The evolution of different ecomorphs on the Caribbean islands is an example of stabilizing selection.



Answer: False

(Why: The evolution of different ecomorphs is an example of disruptive selection. Each new ecomorph had characteristics that were ideal for a particular habitat, but as these characteristics developed, the lizards lost the ability to survive effectively in the other habitats on the island.)

True or false? Convergent evolution is said to have occurred if the mouse species on two islands with similar habitats are found to have similar characteristics even though they originated from different species.

True or false? Convergent evolution is said to have occurred if the mouse species on two islands with similar habitats are found to have similar characteristics even though they originated from different species.



Answer: True

(Why: Convergent evolution occurs when selective pressures produced by similar conditions (such as habitat) favor the evolution of similar solutions.)

Answer: Trunk/ground
(Why: these ecomorphs need long legs to jump from one broad perch to another.)

Which of the following statements about the evolution of Anolis lizards in the Caribbean islands is true?

Which of the following statements about the evolution of Anolis lizards in the Caribbean islands is true?



Answer: The phylogeny of ecomorphs on a given island reveals that adaptive radiation has taken place.
(Why: This statement is true; the historical evidence of adaptive radiation on an island is recorded in the evolutionary history of the ecomorphs currently living on the island.)

Which of the following devices does not segment the network?

Which of the following devices does not segment the network?



Answer: Hub

A hub does not create multiple segments on the network. A segment is a portion of the network that has a different media, collision domains, or broadcast domains. A hub simply connects devices using the same media type. All devices are members of the same collision and broadcast domains.

On a switch, each switch port is in a separate collision domain. With a router or a firewall, each connected network is a different broadcast domain.

An 8-port switch receives a frame on port number 1. The frame is addressed to an unknown device. What will the switch do?

An 8-port switch receives a frame on port number 1. The frame is addressed to an unknown device. What will the switch do?





  1. Send the frame out port 2-8.
  2. Because the switch does not know the port that is used to reach the destination device, it will send the frame out all ports except for the port on which the frame was received. After the switch learns the port that is used to reach the destination device, it will send the frame out only that port.

Which of the following hardware devices regenerates a signal out all connected ports without examining the frame or packet contents?

Which of the following hardware devices regenerates a signal out all connected ports without examining the frame or packet contents?





  • Repeater
  • Hub


A hub and a repeater send signals out all other ports. These devices do not examine the frame or the packet contents.

A switch or a bridge use the MAC address in a frame for forwarding decisions. A router uses the IP address in a packet for forwarding decisions.

How do switches and bridges learn where the devices are located on a network?

How do switches and bridges learn where the devices are located on a network?




  1. When a frame enters a port, the source MAC address is copied from the frame header.
  2. Bridges and switches learn addresses by copying the MAC address of the source device and placing it into the MAC address table. The port number which the frame entered is also recorded in the table and associated with the source MAC address.
  3. The switch or the bridge cannot record the destination MAC address because it does not know the port that is used to reach the destination device. Bridges and switches operate at Layer 2 and do not use IP addresses (which exist at Layer 3).

Which of the following best describes how a switch functions?

Which of the following best describes how a switch functions?



Answer:


  • It connects multiple cable segments (or devices), and forwards frames to the appropriate segment.
  • Switches have multiple ports and can connect multiple segments or devices. The switch forwards frames to the appropriate port. They function similarly to a hub, except instead of sending packets to all ports, switches send packets only to the destination computer's port.
