The Seattle Biomedical Research Institute is doing research on malaria vaccines. They are wanting to find out if the vaccines work. Since they do not know if the vaccines work, they are looking for volunteers who will try the vaccines and then hold a cup of mosquitoes that are infected with the most deadly form of malaria to their arm so they are bitten. This study is a continuation of a study that start at Walter Reed Army Institute of Maryland is is funded by the Bill and Melinda Gates Foundation.

Since people are being asked to be infected with malaria, this brings up all kinds of ethical questions. First of all, would these people get seriously ill and even die? According to the researchers this would not happen and people would only have flu like symptoms for about a single day.

However, while the researchers may be able to try to control the mosquitoes to the best of their abilities, it is uncertain that these people may not have some type of allergic reaction or end up getting some type of disease or other infection from the mosquitoes.

Also, would malaria spread if these people are out in the community? Researchers say that the malaria will not get to a point where it is infectious from person to person. Most likely this is true since they know the research that has already been happening.

Of course, the volunteers are given $2,000 for participating. The researchers have said that this is mainly compensation for missing work or replacing funds used to get to the site and any other costs volunteers may incur.

While this sounds a little bit on the dangerous sides, there are benefits as a whole. People really do care about others in third world country who are often infected with malaria and do not survive because vaccines do not exist and they cannot afford the medication. Thus, people who want to make sure that vaccines will be available to these people may have an urge to volunteer for this program.

While I like the idea of getting vaccines to people in third world countries, no amount of money would make me go get a vaccine that may or may not work and be infected with a possibly deadly disease. While I know that only flu like symptoms should occur, I would be scared that something would go wrong.

I want to live my life and not be willingly infected with a disease. I would be scared that I'd have something in my body or have some type of reaction either to the vaccine or to the disease that would end my life suddenly.

While I know that I can't control the length of my own life, I can try to take care of myself so I have a good life. I want to be able to spend time with my friends, my family, and my dog. If anything were to happen because of this, the money, no matter how much of an amount, would not do me any good. While it could help my family, it would not ease the pain of the loss.

I'd rather earn my money honestly than making myself into a medical guinea pig.

You mean you had to GO to the library to do research?

Understanding Research Types:
Basic: Seeks to create new knowledge and is not directly related to technical or practical problems. Example: analyze the types of information systems used by people with disabilities.

Applied: Seeks to solve problems. Example: A study conducted on how information systems can be used to improve communication with people with disabilities.

Research Terminology:
There are many types of research and each type of research can utilize different methods for collecting information. This glossary can be utilized to clarify the research terms you may come across during your search. In addition, this glossary is a good resource for refining questions you may have of your professor regarding the assignment.

Case Studies: Examines in-depth the practices or trends of a single or limited number of groups. According to the Second Edition of the Dictionary of Sociology edited by Gordon Marshal, case studies include "descriptive reports on typical, illustrative, or deviant examples; descriptions of good practices in policy research; evaluations of policies after implementation in an organization; studies that focus on extreme or strategic cases; the rigorous test of a well-defined hypothesis through the carefully selected contrasting cases; and studies of natural experiments."

Empirical Studies: Research based on critical evaluation through observation or experimentation.

Experimental Research: Examines the relationship between two variables. This type of research conducts experiments on test and control groups to test a hypothesis about the relationship between two variables.

Historical or Interpretive Research Studies: By examining past events and procedures, this type of study attempts to predict future events or make suggestions for future actions. Types of historical or interpretive research studies include: biographical; histories of institutions and organizations; investigation of sources and influences; editing and translating historical documents; studying the history of ideas; or compiling bibliographies.

Qualitative Research: Observes the experiences of a particular group and attempts to understand the actions and reactions of the group. Field studies and ethnographic techniques are examples of this type of research.

Survey Research Studies: Examines small groups of the population in order to learn about the larger population. Observation of the smaller group produces data about the larger population. This data is used to predict future actions or results.

User Studies: Research that evaluates the way in which systems or institutions are utilized and how the needs of users can be addressed.

Identifying Research Articles:
Listed below are some clues to help identify research articles. However, it should be noted that numerous exceptions occur for all of the points listed below. Therefore, the following information should be used as a guideline when looking for research articles

Topic: Research articles tend to be highly specific in nature, relate to a particular field, or specialty within a field, and are written by authors who have done research in the field.

Audience: The target audience is other researchers, colleagues, students and specialists in the same field. Research articles are written for the scholarly community, rather than a general audience.

Language: The language of research articles is formal, generally does not use the first person, and includes jargon used in the field. Research articles are written to contribute to the knowledge base of the discipline.

Length: research articles can vary in length, but are typically five to fifty pages long.

Authors: Research articles may have numerous authors. The organization, institute or professional society the authors belong to will be listed.

Content: Generally the article is written at a sophisticated enough level that the reader will need to read the article more than once in order to understand and evaluate the article.

Identifying Refereed Journals:
Listed below are some clues to help identify refereed journals. However, it should be noted that numerous exceptions occur for any and all of the points listed below. Therefore, the following information should be used as a guideline when looking for refereed journals

Issue identification: Each issue has a publishing date, volume number and issue number. Generally a volume number is consistent throughout the calendar year, with each issue assigned a corresponding number e.g. vol. 55, issue 4.

Length: A refereed journal may have one to fifty articles, with most having eight to eighteen.

Advertising and graphics: Very little, if any, advertising is included in refereed journals. Any advertising that is included will directly relate to the field. Generally journals of this nature do not have photographs and use black print on white paper. The size of the journal may vary in size from a small paperback size to a large magazine format.

Table of contents: In addition to research articles, refereed journals may contain book reviews, literature reviews, and essays. Therefore, just because an article is published in a refereed journal, it does not necessarily mean that it is a research article!

Publishing: Refereed journals are usually published regularly - once a week, once a month, every quarter, or annually. The majority of journals are published four to six times per year and are often published by a professional society, organization or research institution.

Editorial board: Refereed journals have a peer review process. The editorial board is listed (generally at the beginning of the journal) along with the organizations they are affiliated with. Information about what types of papers are chosen for publication, the selection process, the length of papers accepted, and how to submit a paper is also provided.

Indexing: A listing of where the refereed journal is indexed is often provided.

Title: The title of a refereed journal usually has an "academic" sounding name.

Availability: The location, call number, and availability of the journal can be determined by using the online catalog.

Refereed Materials:
Refereed materials are publications reviewed by "expert readers" or referees prior to the publication of the material. After reading and evaluating the material, the referee informs the publisher if the document should be published or if any changes should be made prior to publication. Refereed materials are also referred to as Peer Reviewed. Refereed materials are significant to the research and the literature of library and information science because they assure readers that the information conveyed is reliable and timely.

Non-Refereed Materials:
Non-refereed materials such as Trade Journals or Magazines use less rigorous standards of screening prior to publication. In some publications, each article may be only screened by the publication's editor. While knowledgeable, no editor can be an authority on all the subject matter printed in a journal. Other non-refereed materials accept almost anything submitted in order to have something to print. The term "scholarly materials" is often used to describe refereed materials, but this term is not exclusive to refereed material. Non-refereed materials may not by scrutinized as intensely as refereed materials, but they can still be considered scholarly.

Locating Materials:
Databases are repositories of article information from journals, magazines, conferences, and sometimes books and newspapers. Databases cover a wide range of topics. Some databases offer a full text feature that links you directly to an article, so you can download and print it directly off the Internet. Explore databases that you use regularly to determine if they have this feature (usually denoted by an "FT" next to the article citation).

Evaluating On-line sources:
Online sources can be a valuable tool if you know how to accurately assess the value and validity of the online information source. In trying to determine the validity of a webpage, it is useful to see what type of organization publishes the page. Sites ending in .edu or .gov are generally more accurate and trustworthy than most, since they emanate from academic and governmental organizations. It is important to verify that you are not looking at a student page located on an academic server, which may or may not be as trustworthy as a page produced by the school. Another element to be cautious of when evaluating your potential source is bias. For example, if you are looking at a commercial site, are they accurately portraying information, or bending the truth to fit their needs? The next criterion to evaluate is accuracy. Begin by looking for spelling mistakes, poor grammar, and typos. Next, look at the sources quoted within the page. Are they well-known, trusted sources and people with expertise in the field at hand? If the page is valid, accurate, and published by a trusted source, then it is generally considered acceptable for research purposes.

Search Strategies:
Your search strategy will vary depending upon which database you are using. Research articles' abstracts & include terms that most non-research articles' abstracts do not. Some examples of these terms are methodology, hypothesis, research, experiment, etc. You can search the field "Words Anywhere" for these terms while simultaneously searching for the keywords of your topic. If you retrieve too many or too few hits, narrow or expand your search by adding or dropping search terms.

Researchers are currently testing an artificial blood on unconscious patients and this is creating an ethics debate. The artificial blood is called PolyHeme and is made by Northfield Laboratories. Ethicists have weighed in on both sides of the ethics question.

The artificial blood has been tested in earlier hospital studies and most have shown it to be safe. However, there was one study on PolyHeme that was halted after 10 of 81 patients given it had heart attacks and two died. None of those receiving standard treatment had a heart attack. Those who are concerned about the ethics of the current study have pointed out that no one is being informed of this study.

The research on artificial blood works this way. The community where the testing is to be done is informed by researchers about the study. Those who do not wish to be part of the study in case they have a serious accident can opt to wear a special bracelet. If paramedics see no bracelet, they open a sealed envelope that tells them to give either a standard saline solution or the artificial blood. The artificial blood continues to be given for 12 hours once the patient reaches the hospital. There are several ethics problems posed by the research. In the first place, the community is really not being well informed about the existence of the test on artificial blood.

In 1996 Congress passed a law that allows a bypass of the rules on informed consent when dealing with an emergency, potentially life saving research. Supporters point out that PolyHeme, the artificial blood, could save as many as 100,000 lives a year in the U.S. Dr. Richard Garnellie says we don’t ask permission to commence CPR and that the ethics of testing artificial blood falls in the same area. “We kind of have a social contract to do the right thing already.”

Kelly Fryer-Edwards who studies ethics at the University of Washington Medical Center says that it would be difficult to find people to volunteer for a study of trauma patients because people don’t like to think about being in an accident. However, she feels that the attempt has been made to get informed consent. “You’re putting the responsibility on the person who wants to opt out…you have respected their autonomy by giving them that choice.” She feels that emergency research makes all approaches to research ethics go out the window—protecting subjects, getting informed consent.

Vera Sharaw, president of the Alliance for Human Research Protection is opposed to the research on artificial blood on ethical grounds. She says the study “is another one along that slippery slope that’s essentially demolishing your individual right not to become experimental subjects unless we give prior, voluntary, informed, comprehending consent.” She feels that the people who want to be in the study should be the ones wearing the bracelets.

Nancy King of the University of North Carolina has a third ethics concern. She agrees with those who support the experiment to use artificial blood in the field where blood can’t be typed. However she is opposed to its continued use for twelve hours after the patient has reached the hospital where it takes 20 to 30 minutes to type blood. She points out that giving human blood is the current standard of treatment once the patient reaches the hospital.

Several ethicists have pointed out that those most likely to be subjects of the research are from disadvantaged communities.

The University of California at San Diego School of Medicine has come up with the following questions for those interested in the ethics of research into artificial blood in emergency situations:

1. What ethical issues does this case raise for the process of informed consent?

2. Was the waiver of consent that exists for research involving emergency treatment appropriate in this case and if so, why?

3. From the community standpoint, who speaks for the interest of (potential) participants? Should more have been done to ensure their safety and well being and, if so, what?

4. In what circumstances, if any, is it ethically acceptable to draw a disproportionate share of its subjects from a disadvantaged community?

These are all good, difficult questions that should be answered by anyone interested in the ethics of giving artificial blood in emergency situations.

How often does a newspaper, magazine, or net source publish reports of a test or study? It's difficult to read any source without finding some research cited. But not all research data is created equally, nor is every study definitive.

You've probably heard that statistics can be used in any number of ways, to prove points valid and invalid. Propaganda uses statistics-often from the same research of the individuals/groups the propaganda is railing against.

It's important to be able to evaluate the study findings and research reported. All too often what we read are the headlines-after all, they are meant to catch our attention-and spend less time on the details of the reports. But people can make decisions based on poorly developed studies and skewed research data.

Remember when eggs were thought to be a healthy food, then years later they were nearly verboten, and once again they are enjoying a comfortable place in our diets? Coffee is good; coffee is bad; coffee is acceptable again. These are relatively innocuous examples of various study results printed over the years. But much of the research printed is about topics that can affect our health, our finances, our quality of life.

How do we go about evaluating the information that bombards us from every direction? First we have to look at who/what was behind a particular piece of research?

For example, was a pesticide company the funding source for a study on the safety of chemicals used in pest control? Funding sources are not always evident, but if the information interests you, with a little delving on your part, you can find out this important information.

Research that begins by trying to prove a certain point or move in a particular direction is not research that will provide unbiased results. Limitations of analysis are ignored; some data may be ignored-anything that doesn't point to the central idea behind the research will be dismissed.

Be wary of research that doesn't address other sides of the issue. There is rarely one perspective on available information-if so, there wouldn't be much need for research. Open-ended thinkers and researchers will address alternative views, if only to show how this particular study/research logically makes those alternative views less forceful.

When you read about studies involving groups of people, it is important to note how many people were involved in the study, what criteria was used to choose those who took part in the study. The smaller the group of people involved in the study, the less reliable the outcome will be.

Over what period of time did the study take place? For example, in medication studies, a short time period might indicate that potential side effects did not have sufficient time to develop. Reports of such a study that show few side effects were found might not represent the truth of the matter.

A valid study can be replicated. Are there other studies on the same issue? If so, what conclusions did those studies reach? Evaluate the additional studies by the same criteria used for the initial results.

What credentials does the study/research author have? Are there reputable references cited in the material? Does the tone of the information attempt to persuade or is it presented objectively?

All these questions and more will aid you in evaluating the quality of the material you read, no matter the media source. In this era of information overload it may seem overwhelming to take the time to evaluate what you read, but it is important that you do before you alter your way of life based on inferior information.
