Consumer Health Information - Coursework Example A major advantage of using the internet is its relative cheapness that allows many people to access information about their health and other medical issues they would like to know about without having to pay the high consultation fees that are charged by many doctors and other specialists. Conversely, a major disadvantage of using the internet to search for medical information pertains to the credibility of some of the web pages. This is because some of the web pages are created by people without the appropriate amount of knowledge in the topic they discuss in those web pages. The use of the internet provides empowerment to the users as they are able to get information pertaining to various health issues they seek to know quickly and cheaply. This saves them both time and money and enables them to make various decisions that better their lives.

Healthcare organizations provide very important services to the patients that get treatment and other health services provided by these organizations.

Smoke a lot. Drink more of what you have been drinking and try some new stuff. Eat real crappy food. Now go and exercise for ten minutes and soon you will be giving Arnold Swartzenegger a run for his money. Life is good when you are a guy in this day and age, especially when it comes to advertising. Recently I picked up an edition of the latest magazine, Maxim and after reading, starring, and goggling I feel like I have just left a bachelor party. Ad campaigns that are directed toward the male species believe it or not are constructed very simple: sex, booze, money, and did I mention sex? These are the very basic infrastructures of the male psyche. It is hard to believe that after a million years of evolution, placing a man on the moon, and constructing mile high buildings the basic ingredients to a successful advertisement to entice men to buy can be reduced down to sex or how to get it. The January edition of MAXIM magazine (Maxim, 1999) that featured the model/actress Shannon Elizabeth in a very skimpy top is very typical of what men want to see. The cover stories included, "Her secret sex fantasy" and "100 women tell you what really turns them on!" Right. I hate to be a skeptic but why would women want to tell me what turn them on especially after they have kept it a secret up until this point, at least that's what my dad says. On the other hand this could be the new Bible for men. The article of course is an advertisement for a book that I can easily purchase for a measly $9.97 plus shipping and handling. The ad instructs me that this is the latest book from Maxim's secret vault and it is so hot that it should be illegal! Illegal? It is also packed with scorching photos that are too hot for them to show! As I read on I am instructed that I will not believe it till I see it! And I must act now to receive a complimentary poster for the first 100 orders. I thought to myself that perhaps they should have offered a free cold shower because that what I needed after I goggled at the ad for a minute or two. This of course is a typical ploy of marketers according to Jeffery Shrank in "Why you buy-how ads persuade"(Shrank, 1994) in which an illustration is made depicting a technique to persuade using buzzwords.

Senior Geography Project

I have chosen to pick Broadmeadow for the area, as whilst I got robbed, many other community members got robbed on the same day, by the same person. This area seems relevant to my investigation and should provide some interesting results. The area is also very close to home, so I wouldn’t need to go out of my way to get to the place needed for investigating. The three aims that I have chosen all relate back to the robbery that took place in my home. I want to investigate if this was just coincidence or if this is happening across the whole board.I also want to investigate the security measures people have put into place to counter this criminal aactivity. Aims of the topic: 1. To investigate the trends in Crime Rate over the last 5 years 2. To investigate the security measures people have put into place 3. To identify major types of crime Hypotheses: 1. Over the last 5 years, I think that the crime rate has slowly increased, to its peak. On the radio/tv/computer I hear about d ifferent robberies daily. I think this trend will have an affect across all of NSW and Australia. 2. In Broadmeadow, I think that people will have ssimilar security measures as one another.I think this would be because of council regulation and what other people in the neighborhood have recommended. 3. I think that the most common form of crime in the Broadmeadow area would be either theft or break and enter. Due to the large amount of criminal aactivity in the area. Plan of Investigation/Methodology Steps for Research: 1. Find topic – research if applicable in area 2. Find aims, hypothesize the aims 3. Rationale of the topic 4. Finding of ways to collect and provide examples 5. Walk around Broadmeadow area and recording security measures 6.Interview police on crime rates/ major types of crime in Broadmeadow 7. Research on the internet the verify findings 8. Analyse information 9. Evaluate findings 10. Does this support or refute the hypotheses? 11. What are the implications of the findings Explanations: 1. Whilst walking around the Broadmeadow area, I will record what security measures owiners have on their houses into a table. This will include 50 houses from 3 roads – Everton Street, Dumaresq Street and Blackall Street. Next I will gather all this data and find the ppercentage of each security measure.Next I will analyse these findings and compare them to findings on the internet and make an appropriate conclusion either supporting or refuting the hypothesis made. 2. I will create an interview based on the findings of the previous research. These questions will involve finding statistics on crime rates/major types which I can then relate back to the previous research found. Once the data has been recorded, I will separate these findings into two graphs; One graph will show the deviation in in crime rates, the other will show major types of crime and the security measure most affected by this.

Management Information System Case Study - 1251 Words

Question: 1. In the case study, we referred to the systems being developed and used as decision support systems. However, we also identified various artificial intelligence (AI) technologies. How can a decision support system incorporate and use AI technologies such as pattern recognition? Answer: ARTIFICIAL INTELLIGENCE (AI) tools and techniques can aid in the diagnosis of disease states and assessment of treatment outcomes, so AI can be used by a decision support system as pattern recognition to analyze healthcare data and generate a representation of knowledge and make a decision support. One of this AI technologies tools is the Artificial Neural Networks which work much like the human brain and have the ability to learn from†¦show more content†¦But If I am in this case, or if I’m going to be their patient, I would probably choose opt-in because I know that this my health profiles are really needed for them to determine the appropriate therapies for me and of course it is also for my own benefits so I will allow their system to use my profile. Question: 3. In this case, demographic information such as ethnicity, gender, and age greatly impacts the quality of the decision support and analysis. The same could be argued for the predictive analytics system used by the Richmond police in this chapter’s first case study. Why would some people find it acceptable to use such demographic data in this case (for medical purposes) and not in the first case (for predicting crime, its location, and its timing)? Answer: For me the demographic data is really meant or better to use for medical purposes than for predicting crime. â€Å"Woman ages from 60-80 are prone to osteoporosis.† is an example of what I always heard about health. I believe that there are diseases for specific age or gender, for example uterus cancer is for woman only and alzheimers disease is for adult and not for children. And for ethnicity, I think people’s health will also be affected from their environment, the way they live or the food they eat. So this demographic data is really used in medical purpose.

Mayo Clinic Paper - 977 Words

Mayo Clinic Paper Molly Sjurson Management 4450 February 1st, 2011 Mayo Clinic is a not-for-profit clinic which helps provide unique care to every individual patient through education, research, and practice. Mayo Clinic’s website provides services such as online office visits, secure messages, medical records, upcoming appointments, online bill pay, prescription refills, and registration updates. Mayo Clinic employs physicians, students, scientists and allied health personnel in order to follow the Clinic’s philosophy of â€Å"the patient comes first† as one of the largest clinics with over 1,700 medical doctors achieving high quality at a low cost (1). Many people have begun venturing online to self-manage their health and are looking†¦show more content†¦The Mayo Clinic medical directory is easy to use and provides up to date information on diseases and symptoms put together by top notch MD’s on the editorial staff (3). These highly notable disease indexes landed the website a spot in Time Magazine’s à ¢â‚¬Å"50 Best Websites 2010†. Mayo Clinic’s original material sets the company apart from other encyclopedic websites like WebMD and Healthline which do not have the simplistic navigation Mayo Clinic offers(4,5). WebMD and Healthline do not offer easy to understand explanations for the diseases listed. Mayo Clinic utilizes over 40% of the company’s resources for research rather than just medical practice. The teams of doctors that are putting together the information on the website are highly skilled in many different areas of medical study. Mayo Clinic is a not-for-profit organization and therefore thrives on contributions, grants, and endowments from benefactors around the country (7). Due to this factor the company cannot gain any revenue from the website. All information and service the website provides is free of charge.

The Topic Of Nutrition - 1765 Words

Whilst ‘misconception’ is defined in the Oxford Dictionary as ‘a view or opinion that is incorrect because based on faulty thinking or understanding’, they can also be useful to teachers, as it enables us to assess what the children already understand. This can them inform their planning of how to carry out the next useful steps in their learning, by purposefully and directly addressing these naive ideas, to break down barriers in the children’s learning and help them flourish. Children gather pieces of information during their childhood, which may be wrongly pieced together or misunderstood, leading to distorted knowledge or ideas. Within the topic of Functioning of Organisms, I have found some misconceptions relating to the sub-topics of nutrition, plants and bacteria and have addressed how I, as a teacher, would begin to correct them. One common misconception in primary science, relating to the topic of nutrition is that all fat is bad for humans when it is consumed. This is found in children of all ages, as we are taught from a very young age that eating foods with high levels of fat is always bad for our health, as we are overwhelmed by the media and other messages telling us that eating fatty foods will lead to high levels of obesity, which leads to other health issues such as heart disease and arthritis. The prevalence of this has driven the population to believe that any intake of fat is bad for us, but this is not the case.
