[3] The emission of particles from a radioactive mass constitutes a Poisson process with emission
rate 2.5 particles per second. (a) Find the probability that at least two particles are emitted in the
first two seconds the mass is observed. (b) If no particle is emitted in the first second, find the
probability that a particle is emitted in the next second. (c) Find the expected time until the
emission of the first particle.

1) The artificial intelligence algorithms that suggest or display content on YouTube, Facebook, and other social media sites rely on programmatic rules, making these systems a form of one-to-one marketing CRM metrics rules-based marketing sales funnel management marketing automation 2) Imagine if YouTube and Facebook were government-funded public utilities that didn't rely on advertising revenue and therefore had no need to use marketing analytics to shape ad sales. What effect might this have on the radicalization problem that Zeynep Tufekci describes? It would radicalize people even more because neither platform would be bound by advertising regulations. With no economic incentive to keep people engaged for as long as possible, neither platform would have a reason to serve up radicalizing content. Without the lure of being fed a constant stream of emotionally charged content, people would gradually abandon both platforms. Few people would want to use government-run social media, so neither platform would contribute much to radicalization. 3) How does the practice of marketing analytics contribute to the social media radicalization problems that Zeynep Tufekci describes? By giving social media platforms accurate data on how people respond to online content, these systems can keep suggesting content that is more and more radical. By giving social media platforms accurate data on how people respond to online content, these systems can separate emotional responses from logical responses. The analytics results give consumers more control over the content they see when they visit social media sites. Because no products are being sold from social media platforms themselves, marketing analytics are not relevant here. 4) For advertisers, one of the primary appeals of social media is the phenomenon of community building, in which people with similar interests connect online. In light of what Zeynep Tufekci describes in this video, how are advertisers likely to view "communities of belief" that form around extreme opinions? Advertisers will be extremely cautious about being associated with hate speech and other forms of extremism. Companies will include notices on their YouTube and Facebook ads to say they don't agree with extremist content. Just as much of the U.S. population has done in recent years, most advertisers will align with one side or the other. As the old saying goes, "any publicity is good publicity," so most advertisers won't worry about it. Which of these is the most accurate summary of Zeynep Tufekci's explanation of why YouTube can sometimes "radicalize" viewers by serving up increasingly polarizing content? YouTube is selecting video content based on a person's political preferences. YouTube is effectively censoring some content by encouraging viewers to watch other content, rather than letting them pick their own videos. YouTube is steering viewers toward specific points of view. YouTube is attempting to get people to view more vi.

1) Maria Gomez is a 24 y/o female admitted to the hospital for painful inguinal lymphadenitis. An infectious disease (ID) consultation was ordered to determine the etiology of the lymphadenitis. Refer to the case study infectious disease consult report and respond to the following questions. The HPI details the problem-focused review that allows the consultant to identify the signs and symptoms to conduct a differential diagnosis and ultimately uncover the etiology of the lymphadenitis. The questions asked of Ms. Gomez begin to focus on potential sources of infection, including sexually transmitted diseases, cat scratch fever, wounds from shaving, or respiratory infection. The consultant questions her about sexual relationships to determine if there is a potential for HIV, which is an acronym for ____. a) human imunodeficency virus B) herpes infectious virus C) herpes virus, type IV D) human immunodeficiency virus 7) The ID specialist felt that the condition could be due to staph, which is an abbreviation for _______, which are _____. a) staphylococci; bacteria that form irregular groups or clusters resembling grapes B) staphylococcus; bacteria that form a chain C) staphylococcus; rod-shaped spore-forming bacteria D) staphylococci; long, slender, spiral-shaped bacteria with flexible walls 8) The ID specialist differential included strep. This is an abbreviated form for _____, which are ____________. a) streptoccoci; spiral-shaped bacteria that have flexible walls and are capable of movement B) streptococcus; bacteria that commonly infect wounds and cause serious problems such as toxic shock syndrome c) streptococci; bacteria that form a chain, some species are harmless and others cause illnesses D) streptococci; bloodborne bacterial infection transmitted by the bite of a vector 9) Another differential test was to rule out cat scratch fever that could be diagnosed by the presence of Bartonella antibodies. An antibody is ___________. a) a disease-fighting protein created by the immune system in response to the presence of a specific antigen; e.g., infectious agent B) any substance that the body regards as being foreign, including viruses, bacteria, toxins, and transplanted tissues c) a group of proteins that circulate in the blood in an inactive form D) a substance that produces an allergic reaction in an individual 10) Another differential is clostridium difficile, which is sometimes called an opportunistic infection. This type of infection is ___________. a) a severe, systemic response to an antigen in a weakened host B) a localized cellular response to a normally harmless antigen that is foreign to the body C) caused by a pathogen that does not usually result in illness, but it may when the host is weakened d) an overreaction by the body to a harmless substance that is foreign to the body .

1) how do you account for the high productivity of the cage workers prior to the move in the low productivity after the move? The voucher-check filing unit was a work unit in the home office of the Atlantic Insurance Company. The assigned task of the unit was to file checks and vouchers written by the company as they were cashed and returned. This filing was the necessary foundation for the maln function of the unit: locating any particular check for examination upon demand. There were usually 8-10 requests for specific checks from as many different departments during the day. One of the most frequent reasons checks were requested from the unit was to determine whether checks in payment of claims against the company had been cashed. Thus efficiency in the unit directly affected customer satisfaction with the company. Complaints or inquiries about payments could not be answered with the accuracy and speed conducive to client satisfaction unless the unit could supply the necessary documents immediately. Toward the end of 1952, nine workers manned this unit. There was an assistant (a position equivalent to a foreman in a factory) named Miss Dunn, five other full-time employees, and three part-time workers. The work area of the unit was well defined. Walls bounded the unit on three sides. The one exterior wall was pierced by light-admitting north windows. The westinterior partition was blank. A door opening into a corridor pierced the south interior partition. The east side of the work area was enclosed by steel mesh reaching from wall to wall and fioor to ceiling. This open metal barrier gave rise: to the oustomary name of the unit - "the voucher cage." A sliding door through this mesh gave access from the unit's temitory to the work area of the rest of the company's agency audit division, of which it was a part, locateld on the same floor. The unit's territory was kept inviolate by locks on both doors, fastened at all times. No one not working within the cage was permitted inside unless his name appeared on a special list in the custody of. Miss Dunn. The door through the steel mesh was used generally for departmental buisiness. Messengers and runners from other departments usually came to the corridor door and pressed a buzzer f service. The steel mesh front was reinforced by a rank of metal filing cases where checks were flled. Lined up just inside the barrier, they hid the unit's workers from the view of workers outside their territory, ineluding the section head responsible for overall supervision of this unit according to the company's formal plan of operation. PART II On top of the cabinets which were backed against the steel mesh; one of the male employees in the unit neatly stacked pasteboard boxes in which checks were transported to the cage. They were later reused to hold older checks sent into storage. His intention was less getting these boxes out of the way than increasing the effective height of the sight barrier so the section he.
