Question 2: English

Norovirus in Vermont
PART I. OUTBREAK DETECTION

On the morning of February 5, the mother of a young child called the Vermont Department of Health (VDH) to report a possible foodborne outbreak. The woman’s child, age 5 years, and two neighborhood children, ages 7 and 10 years, had become ill with vomiting and diarrhea within 12 hours of each other. The child aged 5-years had become so sick that her mother had taken her to the emergency department at the local hospital.
The mother reported that her child initially complained of nausea around 10:00 a.m. on Monday, February 2. The nausea was followed by vomiting and multiple episodes of diarrhea. The child was unable to eat or drink anything without vomiting. Toward evening, the child became listless. The woman took the child to the emergency department where she was noted to be dehydrated and that she had a fever. Stool and blood specimens were collected, and the child was treated with intravenous fluids and released.
The mother called the emergency department the following day to receive the test results for her child. A nurse told her that preliminary stool culture results were “negative for the usual bacteria.”
The two neighborhood children had had similar symptoms (i.e., nausea, vomiting, diarrhea, and fever) but had not become as ill as the woman’s child. Their symptoms started a few hours earlier than her child’s. Both had returned to school the day after becoming ill.
The three children usually did not play together but had attended a birthday party on the morning of Sunday, February 1. The mother was concerned about homemade ice cream that was served at the party because she had heard it had been prepared using raw eggs.
After confirming the mother’s information with the emergency department physician, VDH staff called the mother who had organized the February 1 birthday party. The woman reported that her own child was well (except for a cold). Other parents had called her, however, saying that their children had become ill with vomiting and diarrhea.
The woman reported that her son’s birthday party had occurred at a private indoor swim club in Essex, Vermont, close to Burlington. Approximately 30 children and adults were in attendance. The children ranged in age from 5 to 10 years. Not all of the children attended the same school.
Cake, ice cream, and canned drinks had been served at the party. All refreshments had been commercially prepared. The ice cream had not contained raw eggs.
The majority of children had played in the pool at the swim club before presents were opened and cake and ice cream were served. Two children who later became ill had left the party before cake and ice cream were served to attend another birthday party.
The mother provided a list of party attendees, indicating which ones she knew had been ill, and their telephone numbers. She also provided the name and telephone number for the swim club manager.
PART II. HYPOTHESIS GENERATION
VDH investigators notified the district health department of the problem and then contacted the manager of the private swim club. The manager stated that he was dealing with a “problem” and refused to talk with health department investigators. He suggested that they leave their telephone number and he would call them back if he had time.
After VDH investigators stated the reason for their call and reassured the swim club manager that the health department needed to investigate the reported illnesses so that the source could be found and actions could be taken to prevent others from becoming ill, the manager spoke with investigators.
The manager had not heard about the illnesses associated with the February 1 birthday party, but had received reports of illness among other persons who had used the pool during the weekend. Rumors were circulating that participants in the infant-mother swim class (that last met on Saturday, January 31) were sick with “stomach flu.”

The manager provided VDH investigators with the names and contact information for persons who had complained to him about being ill and for members of the infant-mother swim class.
VDH investigators, with the assistance of district health department staff, contacted households of persons who had visited the swim club and reported illness since January 27 to VDH, the mother organizing the February 1 birthday party, or the swim club manager. Investigators asked about specific symptoms, the date of illness onset, and the most recent date the ill person had visited the swim club.

On the basis of these calls, 21 persons were identified as having attended the swim club and having reported being ill (Table 1). Signs and symptoms included vomiting (90%), nausea (81%), abdominal cramps (67%), diarrhea (48%), fever (48%), and headache (43%). Symptoms began a median of 30 hours (range: 8−62 hours) after visiting the swim club.

During the calls, multiple parents, who had been at the pool on January 31 noted that the water in the pool had been cloudy. One parent had reported the pool’s condition to the lifeguard and was told that the cloudiness resulted from chemicals added to the water. The parent later saw another swim club staff member collecting water from the pool for testing. No one reported having seen a fecal incident or vomiting while they were at the pool.
On the basis of the initial findings, VDH investigators believed that the gastrointestinal illness was consistent with norovirus infection. They hypothesized that the virus was spread by exposure to the pool at the private swim club on Saturday, January 31, or Sunday, February 1. The district health department arranged collection of stool specimens from 10 patients for norovirus testing at the Centers for Disease Control and Prevention (CDC), using reverse transcription-polymerase chain reaction (RT-PCR).

PART III. ENVIRONMENTAL STUDIES AND WATER QUALITY INVESTIGATION
On the afternoon of February 5, VDH environmental health investigators undertook a comprehensive evaluation of the private swim club associated with the gastroenteritis outbreak. Investigators met with the swim club manager, the pool operator, and staff on duty during the outbreak period.
The goal of the evaluation was to gain a thorough understanding of the design features of the swim club and its operations so that investigators could explore the suspected source of the outbreak and assess factors that might have contributed to its occurrence.

VDH environmental health investigators learned the following information about the swim club and its operations. The club actually had two indoor swimming pools: a smaller activity pool and a lap pool. The smaller activity pool had been used for the February 1 birthday party and the infant-mother swimming class. The club also had a hot tub, men’s and women’s locker rooms, a sauna, and a party room where food was served for private events (Figure 2).

The lap pool, activity pool, and hot tub were situated close to each other (Figure 2). The men’s and women’s locker rooms were adjacent to the pools. Each locker room had a diaper-changing station. Hand-washing signs were posted throughout the club.

The swim club was popular for children’s parties because the activity pool had a slide. Swim classes were also held at the club; classes for children and infants-mothers were held in the activity pool. The club did not have a snack bar. Food for private parties was brought in by event organizers. Pool staff did not help prepare or distribute food for these special events.
Municipal public water was used to fill the pools. The water in the three pools circulated separately for treatment, moving first through a hair and lint strainer (where the larger debris in the water was removed) and then to a pump. From the pump, the water was forced through a rapid sand filter, where it was then disinfected. After disinfection, the water was heated and returned to the pool through a series of inlets in the pool wall.
Water recirculated continuously in all three pools. State law required turnover rates of 6 hours for the lap pool, 2 hours for the activity pool, and 1 hour for the hot tub. Flow meters measured the flow rate for filtration of the water from each pool.
Liquid sodium hypochlorite was used to disinfect the pools at the swim club. An automated disinfectant feeder was attached to the filtration system, helping to mix the disinfectant with the water. A device operating in conjunction with the disinfectant feeder automatically adjusted the pH of filtered and chlorinated water.
Pool operations at the private swim club were performed by lifeguards. However, they received no standardized training or certification in pool maintenance but took instructions from the pool operator who serviced the pool equipment and made decisions regarding water treatment. Staff reported that they tested the water from each pool twice daily; but no records of the results were maintained.

Because no records of water chemistry were maintained at the swim club, aquatic staff were asked to recall water conditions during the weekend and the quantity, time, and type of chemical solutions they had added to each pool. Staff were also asked about any unusual occurrences (e.g., fecal incidents, vomiting, or deviations from normal operating procedures).
On Friday, January 30, no abnormalities in pool water appearance were noted by staff, and testing of water from all three pools was reported as being “normal”. Staff had reported a marked cloudiness of the water in the activity pool on Saturday and that patrons had complained about the cloudiness. No action was taken, despite complaints from patrons concerning water quality, because the pool operator was off-duty.
The cloudiness of the activity pool persisted through Sunday morning, February 1. Chlorine and pH readings taken by staff at that time were “below acceptable standards.” The pool operator was called, and staff were instructed to superchlorinate the pool with several cups of 65% calcium hypochlorite granules.

On Monday morning, the pool operator returned to duty at the swim club and tested a water sample from the activity pool. The sample revealed a total chlorine of 1.5 parts per million (ppm), a free available chlorine of 0.5 ppm, and a pH of 6.8.

Upon his return to the swim club, the pool operator found a kink in the chemical feed pump tube that supplied sodium hypochlorite to the activity pool water. The kink was repaired and the pool was super chlorinated again Monday night (February 2). The pool operator reported that the chlorine and pH were within normal limits when tested Tuesday morning, February 3. These findings were confirmed by VDH investigators.

The swim club did not have standard operating procedures detailing how to respond to abnormal pool chemistries; how to handle water quality complaints; or how to respond to fecal incidents, vomiting, or problems when the pool operator was off-duty. Because aquatic staff turnover at the pool was high, the swim club manager believed that the pool operator should make decisions about pool problems on a case-by-case basis.

PART IV. EPIDEMIOLOGIC STUDY TO TEST THE HYPOTHESIS
After the environmental health assessment of the private swim club, VDH investigators conducted an epidemiologic study to confirm suspicions regarding the source of the outbreak and to identify risk factors for infection.
The swim club manager estimated that 250 persons had visited the club from Friday, January 30−Monday, February 2. Pool attendance records and contact information were available for swim club members. The club manager also provided contact names for group events held at the pool during this time period.
VDH investigators decided to undertake a cohort study because the outbreak was confined to a well-defined group of persons (i.e., those individuals who had visited the pool during January 30–February 2) and the exposure of interest was known. A cohort study also permitted investigators to identify all cases and calculate attack rates.
Investigators planned to contact swim club members who had been at the club during the outbreak period and persons who had attended the special events during that weekend. Each person (or his or her parent) was to be asked about recent gastrointestinal illnesses; onset of symptoms; specific swimming pool exposures; food and water consumption while at the swim club; use of locker rooms, showers, and toilets; and whether they witnessed anyone vomiting or any fecal incidents at the pool. A VDH epidemiologist developed a questionnaire to collect the information.

VDH and district health department staff members were trained to administer the questionnaire by telephone for the cohort study. Interviews were conducted during February 12−22. Information was collected for 189 (74%) of the 255 persons who had visited the swim club during the period of interest.
A case was defined as vomiting or diarrhea (i.e., three or more loose stools within a 24-hour period) in a person who had gone to the swim club during the outbreak period and who experienced symptoms within 72 hours of visiting the facility. Investigators calculated attack rates and relative risks for different exposures at the club and set a P value of 0.05 as the cut-off for statistical significance.
Fifty-two (33%) of the 160 persons who either swam in or accompanied children who swam in the activity pool met the case definition. Only one (4%) of the 28 persons who only used other parts of the facility (e.g., lap pool, hot tub, or locker rooms) met the case definition. Because of these findings, further analyses were restricted to the 157 persons who either swam in or accompanied children who swam in the activity pool and who provided investigators complete information.
Attack rates were 0% (0/21) for persons who used the activity pool on January 30; 57% (25/44) for persons who used the pool on January 31; 29% (22/75) for persons who used the pool on February 1; and 12% (2/17) for persons who used the pool on February 2. Six persons, including three who were ill, had exposures to the pool on multiple days. Attack rates also varied by other exposures in and around the activity pool (Table 2).

In the cohort study, going into the activity pool at the private swim club was significantly associated with illness. Among persons who went into the activity pool, getting water in the mouth and getting splashed in the face were significantly associated with illness. Neither swimming (versus wading) nor using the slide was associated with illness.

Use of the locker rooms or showers at the swim club was not significantly associated with illness. However, eating and drinking at the swim club were significantly associated with illness.

Eating and drinking at the facility accounted for only 18 (35%) of the 52 cases of gastrointestinal illness. Furthermore, investigators noted that persons who ate and drank at the facility were largely limited to children attending the birthday party on the morning of February 1, when the water in the activity pool was highly suspect in terms of maintenance failures and contamination.

When analyses were stratified by date of exposure to the swim club, persons eating at the facility or drinking at the facility were at no greater risk for illness than other persons attending the club on the same day. In addition, multivariate logistic regression analysis identified the date of attendance at the facility and getting water in the mouth were the only factors significantly associated with illness. Investigators concluded that food and drinks were not independent risk factors for illness.

PART V. CONTROL AND PREVENTION MEASURES
The cohort study confirmed suspicions that the outbreak was spread by exposure to water in the activity pool at the private swim club and likely resulted from a fecal incident in the pool when the chlorinator was not functioning properly.

Five of 10 stool specimens collected from ill persons and submitted to CDC tested positive for norovirus by RT-PCR testing. The nucleotide sequences of the amplified RT-PCR products were identical, indicating a single contamination event at the activity pool.
The chlorinator was fixed and, at the time of the pool evaluation, pool chlorine and pH were consistent with recommended national standards.

VDH investigators believed that a lack of pool staff training, inadequate record-keeping, and lack of standard operating procedures contributed to the outbreak. Consequently, VDH investigators recommended that all pool staff at the club be trained in water testing and basic pool maintenance and that the pool operator remain onsite or be readily available for consultation during weekends, when pool usage was usually highest. Investigators also recommended that the club keep records of routine pool chemistries and pool maintenance.

In addition, investigators recommended that the swim club develop written standard operating procedures and emergency response plans detailing how water-quality complaints should be handled, the correct response, and lines of communication to the pool operator. In particular, VDH investigators recommended the development of a fecal incident response policy.

VDH investigators helped the swim club manager and pool operator develop a written policy for responding to fecal incidents. As part of the policy, staff were to document each fecal incident by recording the date and time of the event, whether it involved a formed or diarrheal stool, and the free chlorine levels and pH at the time the event was detected.

Pool management distributed the fecal incident response policy to all swim club staff and held special classes to review the approach to a fecal incident. New staff members received the policy and viewed a short video about the steps necessary to respond to a fecal incident.
After the investigation, members of the private swim club voiced concern about the adequacy of actions taken to prevent future waterborne outbreaks at the club. The club manager asked VDH staff to meet with interested club members.

EPILOGUE

The number of recreational water-associated outbreaks in the United States has increased substantially since 1978 when CDC first began collecting reports.3 The increase has been caused by outbreaks of gastroenteritis (Figure 3) and likely results from a combination of factors, including the emergence of chlorine-resistant pathogens (e.g., Cryptosporidium), increased participation in aquatic activities by the public, and an increased number and variety of aquatic venues.

Source: CDC Waterborne Disease and Outbreak Surveillance System
During 2005−2006, a total of 78 recreational water-associated outbreaks were reported in the United States, resulting in 4,412 cases of illness. Fifty-eight (74%) of the outbreaks occurred at treated water venues, resulting in 94% of the cases of illness.
As experienced in Vermont, problems contributing to outbreaks associated with treated recreational water in 2005-2006 include low disinfectant levels, inadequate water-quality monitoring, breakdowns of equipment and lengthy detection times, inadequately trained aquatic staff, and unclear chains of communication for resolving problems. Unfortunately, these problems are not limited to facilities associated with waterborne outbreaks. In a study of pool inspections at six sites across the United States, over half of all pools had at least one violation. Water-chemistry violations comprised 38.7% of total violations, followed by violations of the filtration and recirculation system (38.6%), and policy and management violations (22.7%). Approximately 8% of pools were closed immediately because of public health concerns.4

Prevention of outbreaks in treated recreational water venues is likely to be accomplished only through concerted efforts by pool operators, the public, and public health professionals.

• Pool operators should employ multiple mechanisms to prevent contamination of pools and transmission of pathogenic agents, including effective facility design and pool maintenance. Operators should implement diarrhea-exclusion policies and disinfection guidelines after fecal incidents. In addition, staff should be trained to perform pool operations, enforce policies, and educate young bathers and their parents about healthy swimming practices.

• The public should follow basic guidelines for healthy swimming. They should avoid swallowing water and stay out of the pool when they have diarrhea. Because fecal shedding of pathogens is common, bathers should use appropriate hygienic measures around pools (e.g., showering before swimming, taking children on frequent bathroom breaks, and changing diapers in the bathroom instead of at the poolside). Pool policies and design should support these efforts by the public. Increased public awareness of pool safety issues and action can promote better maintenance of pools by operators.

• Public health professionals should lead prevention efforts that include surveillance, health education, epidemiologic and laboratory studies, and environmental health research. Public health professionals should (1) require and improve training for pool inspectors, (2) update pool codes to stay current with changing pool designs and needs, and (3) lead efforts to educate aquatic staff and the public. They should also work with industry representatives in developing easier, more effective methods for treating pool water. In addition, because the majority of gastrointestinal illnesses can be spread by water, food, person-to-person contact, and animal-to-person contact, investigators should keep an open mind when investigating such cases and consider all possible sources of transmission during the investigation of an outbreak.

Improved pool operator and public education combined with more effective methods of water treatment should increase swimming safety and reduce the risk for waterborne diseases associated with recreational water facilities.

U.S.
Missed Pickup Means a Missed
Opportunity for 30 Seeking a Fellowship
By DEAN E. MURPHY FEB. 5, 2004
A missed courier pickup, an honest clerk and an unyielding federal bureaucracy have conspired to deny 30 college students here the chance to compete for a prestigious Fulbright research grant.
”It seems surreal to me,” said Mary Ann Mason, dean of the graduate division at the University of California, Berkeley. ”It is an unnecessary, foolish, tragic incident.”
The students, all enrolled in doctoral studies, got the news on Tuesday night from the university’s chancellor, Robert M. Berdahl, that their applications were disqualified because they were late. Dr. Berdahl had earlier flown to Washington in a failed bid to persuade education officials in the Bush administration to change their minds.
”For these students to lose out on the opportunity to compete for the Fulbright award in this way is outrageous,” Dr. Berdahl said. ”No one could have imagined the Department of Education could have reacted the way it did.”
The department, which administers the Fulbright-Hays Doctoral Dissertation Research Abroad Fellowship Program, rejected the applications because they were not mailed by the Oct. 20 deadline, according to a letter to Dr. Berdahl from Sally L.
Stroup, an assistant secretary of education.

On that day, the applications were in an envelope at the university’s Sproul Hall for pickup by Federal Express. But the courier did not come until the next morning because of a ”software glitch,” said Sandra Munoz, a FedEx spokeswoman.
The company provided the university with two letters acknowledging the mix-up and accepting blame for the late delivery. It also backdated the shipment’s air bill to reflect the intended Oct. 20 pickup date.
”We realize how serious this is, and the inconvenience we are causing everyone,” Ms. Munoz said. ”We certainly apologize.”
Late in the day on Oct. 20, an employee with the university’s graduate division sent an explanation by e-mail to the Education Department, which told the university to send the applications with the explanation from FedEx, university officials said.
For months, the university officials assumed the problem had been worked out. But the e-mail exchange, Dr. Mason said, came back to haunt them. It was cited last month by lawyers for the department as grounds for rejecting the applications, she said. Since the air bill had been backdated, the correspondence was apparently the only evidence that the applications had not been sent on time.

”The final terrible remark of the lawyers was, ‘If you hadn’t e-mailed Washington, we would have let it go because we wouldn’t have known there was a problem,’ ” Dr. Mason said.
The implicit message, she said, was, ”Honesty is not the best policy.”
A spokeswoman for the Department of Education did not respond to several telephone messages seeking comment. In a statement released Wednesday, Assistant Secretary Stroup defended the decision.
”Although we are very sorry for UC Berkeley’s graduate students who had hopes of Fulbright-Hays doctoral fellowships, the facts are indisputable: UC Berkeley was negligent in failing to mail its application on time, despite the fact that for years the
university has applied for this program each fall,” she said.
”When it became apparent that Federal Express would not arrive in time, a simple trip to the post office would have ensured that the university’s application met the deadline,” she said. ”Sixty other institutions met the application deadline.”
Last year, 15 of the 30 applicants from Berkeley were awarded Fulbright fellowships, ranging from $20,000 to $64,000.
In retrospect, the officials said, it would have been prudent to take the package to a nearby FedEx office or the post office, but no one had envisioned a delivery error would have such consequences. Now, officials are looking to FedEx to bring about some sort of happy ending.
Dr. Mason said lawyers for the university were ”talking with FedEx about sharing some responsibility.” She said one idea was that FedEx would provide some doctoral research grant money.
Ms. Munoz said FedEx was eager to resolve the situation.
”Obviously,” she said, ”our goal is always 100 percent customer satisfaction.”
Jason Seawright, one of the applicants, said that while he would appreciate any help, it would be hard for any other grant to match the résumé-building force of a Fulbright.
”In addition to the money, this is something that opens doors in your career,” he said. ”Right, I’ll put that on my résumé: the FedEx fellowship.”

We ask you to write most of your written paper assignments in with opening and closing paragraphs, a clear purpose that is accomplished in the course of the essay, and logically organized paragraphs that develop your ideas. Please notice what this introductory paragraph accomplishes. As you construct your introductory paragraph, remember to engage the reader and to express the purpose you hope to fulfill in the paper. In addition, the introduction may offer a roadmap or a plan for the paper as a whole.
This template generally follows APA formatting, but there are exceptions. A number of features appropriate for a long manuscript or for a dissertation are not necessary for relatively brief assignments. For example, you do not need an abstract for every assignment.
Throughout your paper, consider the way a paragraph looks on the page. The indentation and length of a paragraph convey a message to the reader, suggesting a brief or extensively developed unity of an idea. Two naturally emphatic places in any paragraph are the opening sentence and the closing sentence. Take advantage of these positions in a paragraph; use them for emphasis and for guiding your reader.
The opening sentence of any paragraph provides a natural opportunity to direct the reader from one idea to another. The sentence may function as a combination topic and transition device, suggesting to the reader where this particular section is headed. You may also use single words or phrases to connect your ideas to one another. Think of transitional expressions such as the following as glue or signposts: also, in addition, moreover, therefore, similarly, in contrast, although, or however. (You will find many more transitional expressions and the punctuation they require in any grammar book or on the Walden Writing Center website). It is your responsibility to demonstrate for the reader the relationship between one idea and another so that the reader never has to guess at the logical organization of your ideas.
Another way that you might wish to indicate organization to your reader is the use of headings. However, in your written paper assignments, no headings are required. If your paper exceeds five pages, or if you think that headings will help to convey the organization and clarity of a particularly complex paper, consult the Walden Writing Center for the correct formatting of the various levels of headings. Remember that headings alone will not accomplish what your writing should accomplish. In other words, your heading may announce “Conclusion,” but if a number of paragraphs introducing new ideas follow that heading, it is rather like a false advertisement and will confuse the reader.
Because this is a graduate program, your writing is expected to reflect Standard Edited English. That is, it is to be grammatically correct, formal, written English intended for silent reading. We do not usually speak in (or listen to) Standard Edited English; in our oral dialect, we naturally use contractions, slang, repetition, and all kinds of interpersonal oral signals to one another. In a rather formal writing context, however, none of those elements of speech are particularly useful or appropriate. In particular, APA style does not allow for the use of contractions (e.g., write it is instead of it’s) or informal slang (e.g., use learners or students instead of kids). Admittedly, the writing that you are submitting for a grade in your master’s courses is more formal than that to which you may be accustomed. Take the time to read your writing aloud; to consult a grammar source regarding some stylistic elements you might have forgotten over the years; to avoid contractions and the use of underlining; and to be sure that your sentences are clear to your reader. Write in your authentic voice but in your most intelligent and interesting voice as well. Imagine what questions your reader might ask you, and then provide your reader with well-developed, detailed, specific ideas rather than vague generalizations.
One essential way to develop your ideas is to ground them in the course materials you have been reading or in additional sources that you discover in the course of your studies. When you refer to the author of a required reading or to a statement by an expert on a video, you are offering a context for your idea that stems from the published research by experts in your field. Conversely, if your thinking remains vague and general and you do not ground your ideas in published references, your ideas are likely to be underdeveloped. Let your readers know that you have read (or viewed) and learned from the writings of education experts by either paraphrasing their ideas or quoting their language and following either the quote or a paraphrase with an in-text citation. For example, if you wanted to quote an extensive passage from Gardner’s The Unschooled Mind, the block quotation format as outlined would be:
We are able to know the world through language, logical-mathematical analysis, special representation, musical thinking, the use of the body to solve problems or to make things, an understanding of other individuals, and an understanding of ourselves. Where individuals differ is in the strength of these intelligences—the so-called profile of intelligences—and in the ways in which such intelligences are invoked and combined to carry out different tasks, solve diverse problems, and progress in various domains. (Gardner, 2004, p. 12)
Note that the block quotation as shown above is double-spaced. When you end your quotation, make sure the next paragraph transitions from that information so your reader can follow you. You might additionally want to include other theorists’ ideas to substantiate the above information. You can insert shorter quotations (fewer than 40 words) by using the format in the following sentence: Knowles (1998), an authority on adult learning theory, most likely described (use past tense for reporting research) adults as “motivated to learn to the extent that they perceive that learning will help them perform tasks or deal with problems that they confront in their life situations” (p. 67). The reader may be so intrigued with this allusion to Knowles’s idea that he or she may wish to follow up by consulting the same reference.
Note that if you are citing information from Laureate multimedia files, you will cite as (Laureate Education, 2016). The year may change depending on the multimedia file. The complete bibliographic information for the cited reference is available in the reference list for your reader to further investigate if he or she chooses. Full guidelines for citing Laureate multimedia files in current APA format appear on the Writing Center website at http://writingcenter.waldenu.edu/624.htm. It is important to know that APA formatting does not support quoting directly from multimedia files. If you use any multimedia as support for your thinking, you must paraphrase and include the cited reference.
A third option open to you is to cite a fellow student’s discussion posting or other shared course work in your assignments to substantiate your own perspective. Citing other students is a way to use all resources available to you, and it demonstrates your willingness to give credit to your online colleagues. For example, in a critical analysis of a source, you might remark that a fellow student named Alex Jones identified an author’s study as “interesting but lacking in practical application to the classroom” (Jones, 2012) to indicate how your views harmonized with those of other classmates. Information on how to cite discussion posts and other more unique references in APA are found at the Writing Center’s citations web page.
Now, glance back over this essay to note that it is a well-developed piece of writing and not merely a five-paragraph, perfunctory essay. Notice the transitional expressions that allow your mind to move smoothly from one idea to the next. Not all paragraphs are the same length, suggesting that the author is able to develop ideas in various ways. Try to determine what single topic unifies each paragraph. Ask yourself, “What question does this paragraph attempt to answer?” All sentences do not look or sound alike either: Some are brief and direct, while others are more complex and flowing. With practice and a bit of extra time, you can create an assignment that not only looks professional but also conveys your ideas powerfully and earns you the grade you seek.
Some program tools can assist you in creating documents with a professional appearance. The MS Word Troubleshooting site can be a helpful resource. If you have Office 365, go to Tools and then Spelling and Grammar down at the bottom of the box. Alternatively, you may use another resource to check your documents by going to Review and then select Spelling and Grammar. When a green squiggle line (indicating potential grammatical error) or a red squiggle line (indicating potential spelling error) appears, right click on the line and you will get a message about the possible error. However, remember that this is just a computer program and therefore not as wise as the judgment of the author who has consulted a grammar or usage dictionary. You might also consider using Grammar, a more comprehensive, free grammar revision tool available through the Walden Writing Center website.
Finally, just before submitting your work to your faculty member, ask yourself, “Have I fully addressed the complete assignment?” Then in your concluding paragraph, end your essay, rather like the last gesture of tying the ribbon on a present. Some writers close an essay with a concise summary of key ideas because there is no need for unnecessary repetition in a brief essay as in the following sentence. In this essay, we have identified, modeled, and directed you to the key requirements. Others like to offer an idea that takes the reader beyond the implications of this particular treatment of the topic. However, you choose to close your essay, do close the door firmly, thereby giving the reader a satisfying sense of completion.

Appendix: Guidelines for Formatting Multimedia Files

Note: Walden’s guidelines for citing multimedia files can be found here:
http://writingcenter.waldenu.edu/624.htm.

Across the courses, the in-text citation is (Laureate Education, date)
Note: The publishing date for multimedia files are found in the Course Syllabus under Course Materials. This is the date you will use in the in-text citation and in the reference entry.

1. If you are using the Multimedia file, the correct formatting is:
Laureate Education. (Producer). (2015). Voices from the field: The 21st century
[Multimedia file]. Baltimore, MD: Author

Note: Use the actual word Author; do not substitute the author’s name. Also, the title of the program is in italics.
2. How do you tell if the multimedia file is in a series or a single source?
Multimedia files that are part of a series will usually be listed as Part 1, Part 2, or Program 1, Program 2, etc. Some multimedia files are clearly labeled as being excerpts from a series.
3. If you are viewing the multimedia files in the Resource section of 6610, the correct reference entry is:
Laureate Education. (Producer). (year). Name of program [Multimedia file]. Baltimore, MD Author.
Note: Use the actual word Author; do not substitute the author’s name. Also, the title of the program is in italics.

Note: Use the above for stand-alone multimedia that are (a), not part of a series and (b), are viewed via a media. The title of the multimedia file is in italics. In the case of a multimedia file that is part of a series, the individual program is not in italics, but the series title is italicized instead.

Question 6: English

Write a 3-4 page extra credit essay of how digital media has affected individual and cultural understanding of and relationship to food.

Digital Project: Food Culture
For this optional, extra credit assignment, you will be tasked with researching food and food culture via various digital channels and using your findings to carve out your own role in the world of digital food culture. The purpose of this assignment is for you to explore how digital media has affected individual and cultural understanding of and relationship to food.
The assignment will be in 3 parts, each of which has its own point value (listed below).
Part 1: For the first part of this assignment, you will do what I like to call “light research” (i.e., informal, without need for MLA formatted citations) on food culture in digital media. In your research, you will spend some time looking through at least three of the following channels: food magazines (online), food blogs (websites), food “influencers” (Instagram, YouTube, etc.), and food television (Netflix, cable, etc.). Make a list of the shows, influencers, magazines, and/or blogs you come across, highlighting specific details about each. Consider making a list/chart/etc. to outline these similarities/differences you see.
Part 2: After you do your research, you will construct an explanation of your findings that is 1-2 pages in length (roughly 300-500 words). This will be a coherent response that utilizes complete sentences and appropriate academic language. Your response will detail what research you did and, more specifically, what factors stood out in your research. Such factors include but are not limited to: the similarities/differences in presentation, major themes, significant flaws, etc. You will, essentially, explain and expand upon the notes you took throughout the research portion (Part 1). Don’t forget to draw conclusions about what this all means!
Part 3: Finally, after you’ve (1) done your research and (2) drawn up conclusions about your research, you will (3) consider what role you play in all of this. In a short response of 100-150 words (a few sentences), you will identify the role you play in the realm of digital food culture. Are you a creator, viewer, or something else? Why/how? To what extent? Identify and explain why and how you play the role you do, and any other relevant details about your engagement with digital food culture.
Again, this is an optional, extra credit assignment. Adhere to the rules above, but have fun with it! Find below the point values for each portion of the assignment:
1. Part 1: 20 points possible
2. Part 2: 25 points possible
3. Part 3: 5 points possible
4. Total: 50 points possible

The University of Manitoba uses thousands of fluorescent light bulbs each year. The brand of bulb it currently uses has a mean lifetime of 900 hours. A manufacturer claims that its new brand of bulbs, which cost the same as those the university currently uses, has a mean lifetime of more than 900 hours. It is known that the standard deviation of lifetimes of the new brand of bulb is 80 hours. The university has decided to purchase the new brand of bulb if a hypothesis test gives significant evidence supporting the manufacturer’s claim at the 3% level of significance. A random sample of 64 bulbs were tested and their mean lifetime was 920 hours. Based on these findings:

Sixteen people (eight males and eight females) volunteered to be part of an experiment. All 16 people were between the ages of 25 and 35. The question of interest in this experiment was whether females receive faster service at nightclubs than males. Each of the eight male participants was randomly assigned a bar, and each of the eight females was randomly assigned to one of these same eight bars. One Friday night, all 16 people went out to the bar. The male and female assigned to the same bar would arrive within five minutes of each other. Each person then waited at the bar and ordered a similar drink. The time (in seconds) until the drink was served was recorded. Some information that may be helpful is shown below:
Females mean = 275 std. dev. = 37
Males mean = 302 std. dev. = 48

The minimum is 2.2 and the maximum is 11.4.
The median is in position (n + 1)/2 = (30 + 1)/2 = 15.5, so the median is the
average of the 15th and 16th ordered data values, i.e., (7.0+7.2)/2 = 7.1.
The first quartile is the median of all data values lower in position than the median,
so Q1 is in position (15 + 1)/2 = 8. Therefore, Q1 = 6.0.
The third quartile is in position 8 above the median (or equivalently, 8 positions
down from the maximum), and so Q3 = 8.0.
The five-number summary is: 2.2 6.0 7.1 8.0 11.4
(b) We calculate the fences:
LF =Q1−1.5IQR=6.0−1.5(8.0−6.0)=6.0−3.0=3.0
UF =Q3+1.5IQR=8.0+1.5(8.0−6.0) =8.0+3.0=11.0
There are two values less than the lower fence (2.2 and 2.8) and one value greater than the upper fence (11.4). These outliers will be plotted as points on the outlier boxplot.
The whiskers extend to the lowest and highest data values that are not outliers (the “new minimum” and “new maximum”), i.e., 3.8 and 8.8.

When the age of a car increases by one year, we predict its selling price to decrease by $1,700.
We know that 81% of the variation in a car’s selling price can be accounted for by its regression on the age of a car. This is the definition of r2, so we know r2 = 0.81. The correlation is therefore
√√
r=− r2 =− 0.81=−0.90
Note that we take the negative square root of r2, since there is a negative association between the two variables.
The residual for this car is

iv. The response variable is the health of the patients’ teeth.
v. The blocking variable is age (one block consisting of the children and the other block consisting of the adults).
Control is achieved by the comparison of the four treatment groups in each block. (Note that blocking is also another form of control. In this case, by using a random- ized block design, we eliminate the possibility of age becoming a lurking variable.)
Yes. Since this was a properly designed experiment using the principles of randomization, replication and control, we can conclude that the treatment was likely the cause of the observed difference in the response.

Question 9: Health Care

For this assessment, you will report on the information that you collected in your interview, analyzing the interview data and identifying a past or current issue that would benefit from an interdisciplinary approach. This could be an issue that has not been addressed by an interdisciplinary approach or one that could benefit from improvements related to the interdisciplinary approach currently being used. Additionally, you will start laying the foundation for your Interdisciplinary Plan Proposal (Assessment 3) by researching potential change theories, leadership strategies, and collaboration approaches that could be relevant to issue you have identified. Additionally, be sure to address the following, which corresponds to the grading criteria in the scoring guide. Please study the scoring guide carefully so you understand what is needed for a distinguished score. Summarize an interview focused on past or current issues at a health care organization. Identify an issue from an interview for which an evidence-based interdisciplinary approach would be appropriate. Describe potential change theories and a leadership strategy that could inform an interdisciplinary solution to an organizational issue. Describe collaboration approaches from the literature that could facilitate establishing or improving an interdisciplinary team to address an organizational issue.

Interdisciplinary Plan Proposal
Write a brief introduction (2 to 3 sentences) to your proposal that outlines the issue you are attempting to solve, the part of the organization in which the plan would be carried out, and the desired outcome. This will set the stage for the sections below.
Objective
Describe what your plan will do and what you hope it will accomplish in one or two succinct sentences. Also, comment on how the objective, if achieved, will improve organizational or patient outcomes. For example:
Test a double-loop feedback model for evaluating new product risk with a small group of project managers with the goal of reducing the number of new products that fail to launch. This objective is aligned to the broader organizational goal of becoming more efficient taking products to market and, if successful, should improve outcomes by reducing waste.
Questions and Predictions
For this section ask yourself 3 to 5 questions about your objective and your overall plan. Make a prediction for each question by answering the question you posed. This helps you to define the important aspects of your plan as well as limit the scope and check its ability to be implemented.
For example:
1. How much time will using a double-loop feedback model add to a project manager’s workload?
a. At first, it will likely increase their workloads by 5 to 10 percent. However, as the process is refined and project managers become more familiar and efficient, that percentage will decrease.
Change Theories and Leadership Strategies
For this section, you may wish to draw upon the research you did regarding change theories and leadership for the Interview and Interdisciplinary Issue Identification assessment. The focus of this section is how those best practices will create buy-in for the project from an interdisciplinary team, improve their collaboration, and/or foster the team’s ability to implement the plan. Be sure that you are including at least one change theory and at least one leadership strategy in your explanation. Always remember to cite your sources; direct quotes require quotation marks and a page or paragraph number to be included in the citation.
Another way to approach your explanations in this section is to think through the following:
• What is the theory or strategy?
• How will it likely help an interdisciplinary team to collaborate, implement, and/or buy in to the project plan?
o Make sure to frame this explanation within the organizational context of the proposed plan, that is, your interviewee’s organization.
Team Collaboration Strategy
In this section, begin by further defining the responsibilities and actions that represent the implementation of the plan. One strategy to defining this is to take a “who, what, where, and when” approach for each team member.
For example:
• Project Manager A will apply the double-loop feedback model on one new product project for a single quarter.
• Project Manager B will apply the double-loop feedback model on all new product projects for a quarter.
Vice President A will review the workloads of project managers using the double-loop feedback model every Thursday for one quarter.
After you have roughly outlined the roles and responsibilities of team members, you will explain one or more collaborative approaches that will enable the team to work efficiently to achieve the plan’s objective. As with the change theories and leadership strategies, you may draw on the research you conducted for the Interview and Interdisciplinary Issue Identification assessment. However, you are being asked to give a more in-depth explanation of the collaboration approaches and look at how they will help the theoretical interdisciplinary team in your plan proposal.
Another way to approach your explanations in this section is to think through the following:
• What is the collaboration approach?
• What types of collaboration and teamwork will best help the interdisciplinary team be successful?
• How is the collaboration approach relevant to the team’s needs and will it help drive success?
o Make sure to frame this explanation in terms of the subject of the plan proposal; that is, your interviewee’s organization.
Required Organizational Resources
For this section, you will be making rough estimates of the resources needed for your plan proposal to be successful. This section does not have to be exact but the estimates should be realistic for the chosen organization.
Items you should include or address in this section:
• What are the staffing needs for your plan proposal?
• What equipment or supplies are needed for your plan proposal?
o Does the organization already have these?
 If so, what is the cost associated with using these resources?
 If not, what is the cost of acquiring these resources?
• What access (to patients, departments, and so forth) is needed?
o Are there any costs associated with these?
• What is the overall financial budget request for the plan proposal?
o Staff time, resource use, resource acquisition, and access charged?
 Remember to include a specific dollar amount in your request.
After you have detailed your budget, make sure that you explain any impacts on organizational resources that could happen if your plan is not undertaken and successful. In other words, if the issue you are try to solve through your plan proposal persists or gets worse, what will be the potential costs to the organization?

Question 10: Science

Write about one of the following subjects: – intellectual property related to information technology OR – computer crime The paper should have an introduction, good and bad sides, conclusion. If you have an opinion about the subject, write about it. You can study a case to better describe the subject of your paper. Also if you have recommendations to fix any problems with the subject of the paper, include them. Avoid blogs because in most cases they are people’s opinions without supporting sources/references. Cite at least 3 different sources. Assume you are writing the paper for college students who don’t have a technical background.

Question 11: Biology

Choose a topic and write a brief (4-5 pages) review (formal essay format) of some scientific articles that relate to a topic covered in the human nutrition curriculum of Biology 102 *note the topic must be somehow related to human nutritional science – if you want to choose a research topic that involves research outside of humans – you must relate it to human biology in some sense.

This must include references to scientifically sound sources (peer reviewed journal articles), and these references must be cited in the correct scientific format.

* no data base links – (do not copy and paste from pub-med)
* web pages can be used as “supportive references” and must also be referenced correctly

Your analysis should include a summary of the hypotheses of the experiments, the results and discussion of the results and most importantly – your opinion of the study. Why did you find it interesting and what did you learn about the topic?

Use the knowledge that you have gained from Chapter 1 to convey the information in a way a scientist would understand.

Marking Rubric:

1. At least 3 scientific journal article references (other resources can be used to support your ideas) that convey different conclusions related to your topic. (1 mark)

2. A brief but well thought out description of the experiments and the results and conclusions (2 marks)

3. Your personal opinion about what the results mean, and why you chose to research this topic. (1 mark)

4. References are correctly formatted (both the embedded references in the text, and the full reference in the Bibliography) (1 mark)

Total = 5 marks

Chapter 1 in your textbook gives you information related to how science is done and how to think critically to evaluate scientific claims. Incorporate this material into your assignment and convince me that the information you are conveying is scientifically sound and comes from a peer reviewed source. An example of a database that will allow you to access these articles is:

(www.pubmed.com)

Your paper must be referenced in a scientifically accepted format (APA) – for an example: look at the format of the references included in the papers you have chosen, or the “endnotes” provided at the end of every chapter in your textbook.

Question 17: History

250 Word Discussion Post on the Transition of Rome from Republic to Empire. Must be cited using Chicago style format, please see rubric before starting. 6. Discuss the transition of Rome from a Republic to an Empire. Is it even accurate to call Rome a Republic before the reign of Augustus? Or is it an empire in every way except for name? Hint: A Roman Empire is different than The Roman Empire.

Question 18: Sociology

In the first part of the term we went through the various perspectives on what the self/individual is and what society/culture is and the relationship between self and society (the individual and culture). We concluded that all the perspectives believe that we are a product of culture (they, of course, had differing views on the individual’s capacity to create society, etc..). 1)So start by simply summarizing this. Explain what culture is (define it and explain it. Use my notes and the textbook. 2) Next, explain how we are a product of our culture. Again, refer to my notes and the textbook. Here introduce your choice of the influencer. Briefly explain cultural values and norms that the influencer embodies. Depending on your choice, you may want to explain the culture industry and its ability to produce human commodities that others consume, etc… 3) If you are dealing with an activist you might want to discuss the political discourses that this person’s identity embodies. 4) Next, from the Foucault lecture on discourse and Mead and Cooley’s lecture, we looked more deeply at how the self is formed. I explained the I-Other relationship and how we need others to emerge as a self. So explain this. In other words, explain how we require others to mirror back to us who we are extra… 5) Next, once you have explained what culture is and how the self is formed…and you have introduced your choice of influencer, you need to begin to answer my questions. What values does the person embody? What do they represent? Etc… And explain who their followers are? Who is the audience and what are they embracing about this person? Who are the haters? 6) The next part is about globalization and the postmodern world. I posted some notes but will lecture on this with reference to your essays tomorrow. Basically, Postmodernity allows us more freedom in becoming our own unique selves. We interact with multiple cultures and multiple discourses and from these interactions, we create a unique self and are thus a complex configuration of identities. Here you will bring in your influencer and build your analysis. It is said that in the postmodern world cultural products, which include human beings, are a complex configuration of identities–a hybrid or fusion of multiple identities–and this has given people more freedom to become what we want to be. But we still have to appeal to the greater of society in order to be accepted or included. So you need to explore your influencer and come up with a conclusion of who they are and how they are an expression or reflection of the postmodern world.

Essay on Biometrics and intersection with technology and law. Follow the outline and please should be well foot-noted!

Biometrics Now/Future/Ethics/Law
Introduction: Fingerprint recognition, voice identification, facial recognition, DNA matching, and signature matching are all forms of Biometric technology. These technologies aim to identify a person’s identity through unique traits and characteristics. Since biometric characteristics cannot be conjectured or stolen, biometric systems present a superior level of security than usual means of authentication such as passwords or pins.

Question 26: Law

This is an exercise in legal problem solving. This assessment task covers material taught in Contracts I and II only.

Assessment tasks exist to help students learn and apply their knowledge. Grades exist to show how fully this goal is attained.
This assessment task must be the student’s own understanding and effort. If the words or ideas used are not your own, then you must correctly reference them using the Harvard/WesternSydU referencing style.
Requests for extensions will only be considered in the most extraordinary circumstances. If you make such a request, you must attach all work done to date on this task to your email, otherwise it will be automatically declined and you will then need to file an application for special consideration. Late penalties will apply to a submission made after the due date without an extension – 10% of total marks per day or part thereof. You should upload your completed work as soon as you are able, without waiting for an email from the unit coordinator granting or declining an extension or for an outcome on your special consideration application, as the Easter public holidays will occur just after submission so your request will not be dealt with until the Tuesday, some 4 days after the due time for submission, or even later.

A deferred assessment task might be granted as a result of your application for special consideration. If so, it will take the form of a 2 hour open book online exam. This will be held after the teaching is finished but before the final exam.

This assessment task is designed to address student learning outcomes 1–4 for the unit:

· Do not attach a cover sheet, as this is built into the Turnitin system. If you do this will impact upon your Originality Report, your word count, and your privacy.
• Format: Double spaced, Arial 12 point, MS Word document. If you do not use a Word document we will not be able to view and mark it. Please note you can download the MSWord App for iPads free via App Store.
• If you have a question about this assessment task, please read the Learning Guide and these instructions, before posting a question to the Discussion Board on vUWS. Do not email the unit coordinator unless your enquiry is of a personal nature. Using the Discussion Board means that every student has the benefit of access to the answers to questions about the assessment task, which is a fairer system for everyone. Do NOT post your actual responses to any of the questions, as this may involve you in possible academic misconduct. Also do not ask for help in identifying how to answer a problem.

QUESTIONS:
There are three questions in this assessment task. Students must answer all questions.

Question 1: 8 marks
Graham wishing to impress his friend Stacey, goes with Stacey to an antique shop. He inspects an antique dining table and asks the shop assistant the price. The shop assistant tells him that the price is $5,000. Graham says to the shop assistant that he will take it and gives his address to the shop assistant to deliver it to his home. Payment will be on delivery.
When the table arrives, Graham telephones the shop and tells the shop assistant that he was only pretending to buy the table and that he had no intention of going through with the purchase. The shop assistant tells him that Graham must pay for the table.
Is there a binding contract between Graham and the shop? Discuss this situation using case law to support any argument you may make.
Question 2: 5 marks
Andrew and Susan married in 2015 and lived together until they separated in 2018. After 12 months of living apart, they came to an agreement in relation to maintenance and property matters. The agreement was that Susan would pay Andrew $250,000 for his interest in their matrimonial home, and that Andrew would pay Susan $1000 per month to contribute to the mortgage payments on this home. Susan paid to Andrew $250,000 but Andrew refuses to make maintenance payments to Susan. Andrew argues that their agreement is not enforceable because it was made in a domestic context. Is Andrew correct? Explain your answer and indicate relevant authority where appropriate.

Question 3: 5 marks
Chris owned and raced some greyhound dogs, who were very successful on the track. Bruce wanted to buy one of them and breed with it. However, when Bruce approached Chris, Chris told him his dogs were not for sale. Bruce increased the price he was offering but Chris continued to say no.
After several attempts Bruce finally said to Chris that he was being a stubborn ox and that dogs can easily die if one was not too careful with what they fed them.
Chris started to fear for the safety of his beloved animals and himself, so he approached another dog owner, George, and offered to sell all his dogs quite cheaply provided it was a quick sale. George agreed to the sale and now has the dogs.
Chris regrets his hasty decision and wishes to set aside the contract for the sale of his dogs. What legal argument could Chris make to set aside the contract for sale? Is it likely he will be successful?
