Evaluating Information



           




            Ladies and Gentlemen
            Welcome to my CTEC blog, my name is Sinh. The topic of this week is
            My mission is pointing out that "Which type of web site/top-level domain might be better for my topic"
            First of all, I want to share some information about "A generic top-level domain (gTLD) is one of the categories of top-level domains (TLDs) maintained by the Internet Assigned Numbers Authority (IANA) for use in the Domain Name System of the Internet. It is visible to Internet users as the suffix at the end of a domain name." It help everyone limit the information which people needed for their goals when they use the Internet.
            For example:
            .aero : the air transport industry.
            .com: commercial organizations, but unrestricted
            .edu: U.S. post-secondary educational establishments
            .gov: U.S. government entities at the federal, state, and local levels
            .net: originally for network infrastructures, now unrestricted.
            Some example:
            My major is Medical Radiology; therefore find out medical information is necessary for me. Today, I recommend to you some website about medical area.
            1. http://med.studentsforlife.org
            Medical Students for Life of America (MedSFLA) is the medical outreach organization of Students for Life of America (SFLA), which began as American Collegians for Life (ACL) in 1988. Since 2006, ACL changed its name to SFLA and helped start over 450 new student pro-life organizations and revamp hundreds of existing student pro-life groups. SFLA has trained over 7,000 pro-lifers at its national conference, weekend training seminars, and one-on-one campus training. MedSFL Awas launched in April 2010 and works alongside the professional staff at the SFLA national headquarters in Mananas, VA.
            For me, this website provide to me many article, the most important is thia website has enough condition for ASPECT.
            2. http://www.medicinenet.com
            Medicine Net.com is an online, healthcare media publishing company. It provides easy-to-read, in-depth, authoritative medical information for consumers via its robust, user-friendly, interactive website.
            Since 1996, Medicine Net.com has had a highly accomplished, uniquely experienced team of qualified executives in the fields of medicine, healthcare, Internet technology, and business to bring you the most comprehensive, sought-after healthcare information anywhere. Nationally recognized, doctor-produced by a network of more than 70 U.S. board-certified physicians, Medicine Net.com is the trusted source for online health and medical information. The doctors of Medicine Net are also proud to author Webster's New World™ Medical Dictionary First, Second and Third Editions (May, 2008) John Wiley & Sons, Inc.; ISBN-10: 0470189282.
            If you are medical student, you don't forget this website. This website provide to us so many information about medical terms. Everything was update everyday. Of course, this website has enough condition for ASPECT.
            3. http://www.clark.edu
            As you know about this website, the website about education. Therefore, this website only provide the information about education. For example: Medical radiography.
            Mission Statement
"The Clark College Medical Radiography Program prepares the successful graduate to obtain an Associate of Applied Science degree and take the American Registry of Radiologic Technologists (ARRT) certification examination. Graduates work in hospitals, clinics and a variety of other health care settings. Medical Radiographers take radiographs of the human body; and these radiographic images are used to make a diagnosis for the patient and their doctor."             4. http://www.medicare.gov
            This website was created by the government, with a purpose help everyone finds out the medical program. This website only provide the information about the government program. People need to know what is program that they have ability applying. There is a good news, that is you can read this website with many languages.
            Eventually,  taking a walk on online is not a easy work, if you did not have specific goal. Thus, need to know what is my goal? and how do I do it? I cannot to find out government information in education area; or I cannot find out commercial information in medical field .If I do not determine my goal; surely, I spend a lot of time for sitting in front of the computer, but I do not have any result.
            Good luck to you and to me.

Types of Information: Focus on search Engines and Web Sites



Hello everyone!
Welcome to the topic of eighth week. We have worked hard from beginning of this quarter. Now, we are preparing for a good final. Of course, everything is not simple, but I always think that you are a good student. You will win. Good luck to you.
Our topic of this week is: "Types of Information: Focus on search Engines and Web Sites"
Our mission is find five search features of the search tool which was upload on Moodle. I read on Research Journal, there is a word "ANDing". I find out its mean on internet, and I want to share with you.
            What is the ANDing process?
            When a source host attempts to communicate with a destination host, the source host uses its subnet mask to determine whether the destination host is on the local network or a remote network. This is known as the ANDing process.
            The AND function has the following properties:
            · If the two compared values are both 1, the result is 1.
            · If one of the values is 0 and the other is 1, the result is 0.
            · If both of the compared values are 0, the result is 0.
            Therefore, we follow this way. First of all, I have five search tool, such as:
           
1.      Ask Advanced Search: Ask search only help us find out the answers which one I want to find. Ask Advanced Search did not have the number of results.
Ex: I put Biology Articles in Google search, I have about 142,000,000 results; but I put Biology Articles in Ask search, I have nothing.
I put "Biology Articles" in Google search, I have about 123,000 results; but I put "Biology Articles" in Ask search, I see some questions articles such as:
What is a good biology article?
What is a good website for Biology articles?
Where can I Find Biology Articles?
2.      Internet Public Library: I think this search is not good, because when you type wrong letter, it did not have synonym for your choose.
3.      About.com: When I put Biology Articles on About search, I receive 18,100 results. Then I put "Biology Articles" on that, I received 15 results. In this search, it did not have synonym, therefore, be careful  when you type wrong letter.
4.      Find Articles: When I put Biology Article on it, I received 35,500,000 results. This search has a synonyms. I feel that it is very fast. When I put "Biology Articles" on it, I receive 18,400 results.
5.      Dogpile:  I think this search is good. Besides that, I see a letter line "Search result from: Google, Yahoo, Yandex." This search did not has numbers of result.
Next, I find out something such as:
            " What is the difference between search engine and metasearch engine?"
·         A search engine is a search tool that usually have their own database of sites they crawl and list in their database, for example Google.
·         A meta-search engine is a search tool that sends user requests to several other search engines and/or databases and aggregates the results into a single list or displays them according to their source.

            "What is a Subject Directory?"
            To locate information on the Web, you either know Web address for a specific site, or search for a topic of interest.
When searching by topic, a huge number of pages will often be retrieved and makes it difficult to identify the relevant resources. Subject directories help to alleviate the problem.
Subject Directories:
·         are created and maintained by the directory's staff
·         allow you to browse Internet resources by different subject categories
·         enable you to search by keywords within the contents of the directories
In this case, I have:
§  Meta- search is Dogpile
§  Subject Directory are About.com, Internet Public Library,
§  The best of the rest is FindArticles
§  Search tool is ASK.COM.

Eventually, I have so many tools for my research. Everything is in the questions such as:
1. What do you want to find?
2. Do you understand all of the tool around you?
3. How do you apply your knowlege about the tools which help you have the best result ?
            Good luck to you again.

Research Journal Part Seven





Research Journal Part Seven
“Finding Articles in Periodical Indexes”
Search statement
Databases, catalogs, and search engines can only find what you tell them to look for. Once you have brainstormed a list of search terms for your topic, you'll use one of these methods to begin searching:
v  Natural language search (what Google uses)
v  Boolean search (what most databases use)
v  Field search (available in most catalogs and databases)
Major errors in syntax
Syntax or format errors are a major problem for most beginning programmers using languages such as C++, Java, and C#.  A syntax error occurs when the programmer fails to obey one of the grammar rules of the language.  Typically this involves things like using the wrong case, putting punctuation where it is not supposed to be, failing to put punctuation where it is supposed to be, etc.
If a syntax error occurs, it's likely that the programmer has made a typo which means that the computer can't understand what the programmer has written. It's like a punctuation mistake in a written sentence.
As an example, often programmers are required to put statements in brackets. If the numbers of opening brackets do not match with the number of closing brackets, a syntax error will occur. Because computer code can get lengthy and complicated, this kind of mistake can be quite easy to make.
Nowadays, programmers can use tools to write computer code that will highlight most syntax errors and warn of misspellings of frequently used programming terms, or if the number of opening and closing brackets do not add up. Such tools are called IDEs or Integrated Development Environments.
Boolean search
You will understand about Boolean search clearly and easily when you see the figures below. You can broaden or narrow your search results by using these Boolean operators:

       AND                 OR                NOT


AND means every term you type must be present in the record. Use of AND narrows, or focuses, your search.


OR means one of the terms must be present in the record. OR is useful for synonyms or alternate spellings of words. Use of OR broadens your search.


NOT means that a term must not be present in the record.
We will apply this guide immediately with example 1. Find Article from Popular Magazine.
The topic for this week is: “Finding Articles in Periodical Indexes”
Going back my last week topic “Photosynthesis AND light intensity”.
My used the tool such as: ProQuest or Academic Search Premier (EBSCOHOST) in order to find article in periodical indexes. You find ProQuest and Academic Search Premier (EBSCOHOST) in website http://library.clark.edu. Moving your mouse to the find letter, appear the line letter Articles and Databases click in that. You will see ProQuest or Academic Search Premier (EBSCOHOST) in the right side.
1.      ProQuest: Click at Proquest, I have advanced search and put my topic in that.
If I put “Photosynthesis and light intensity”.  I have some results such as: Newspaper (121); Magazine (88); Scholarly Journals (4355)
If I put my topic is “Photosynthesis OR light intensity.”  I have some results such as: Newspaper (47258); Magazine (20600); Scholarly Journals (105159)
2.      Academic Search Premier (EBSCOHOST):
If I put “Photosynthesis and light intensity” I have some results such as: Scholarly Journals (797).
If I put “Photosynthesis or light intensity” I have some results such as: Scholarly Journals (27,965)
            We need to know about “What is annotation?” before go to the next step.
“An annotation is a note, summary, or commentary on some section of a book or a statute that is intended to explain or illustrate its meaning.”
             Moreover, we have a citation and an annotation from popular magazine that is Science News.

Annotation
In recent large-scale frauds, management override around the journal entry process was the key contributing factor. Sure, it is possible to make adjustments in the subledgers, but this requires collusion with other organizational departments. Thus, the top-side entry is a favored method for committing financial statement fraud. Given the ability of journal entries to efficiently undermine a financial statement audit, journal entry testing has become a requirement for external auditors. The practical reality is that financial statement fraud occurs in 1% of digital transactions, so improved tools for detection are needed beyond manual review. This is an area where more transaction testing using data analysis can provide a superb defense against management override by performing a more extensive search for unusual ledger activity. Like any tool, computer-assisted journal entry testing has its limitations. It's best to focus testing not on the controls in place, but rather, computer tools allow the auditor or fraud examiner to focus his or her energy on the highest-risk journal entries culled from a full set of entries rather than on a random sample.

Research Article from Scholarly journal
What is a Scholarly Journal?
As you do research for college projects, your professors may ask you to avoid using popular magazines, and may require you to find articles from scholarly journals instead. For some assignments, trade or professional journals may be appropriate. Here are some examples of each type.
  • You are probably familiar with popular magazines. You have seen them at bookstores and public libraries, or perhaps you subscribe to one. They are written for a general audience, and their purpose is usually to inform or entertain.

  • Scholarly journals are written for a much more specialized audience, and their purpose is to report original research and contribute new knowledge in a particular discipline or field. You will find plenty of scholarly journals in a university library, but you will not find them at your local newsstand.

  • Trade or professional journals are also written for a specialized audience but tend to be more practical or "applied" in nature. These are usually aimed at people in a particular industry or profession.

SCHOLARLY JOURNALS
AUTHORS: Researchers, scientists, scholars.
REFERENCES: Authors cite their sources in footnotes or bibliographies, which are often extensive.
PUBLISHERS: Professional organizations, universities, research institutes, scholarly presses.

            Citation for a research article in a scholarly journal, and an annotation:
Works Cited

Annotation
“Leaf nitrogen content and light intensity affect leaf photosynthesis. Responses of cotton (Gossypium hirsutum L.) leaf photosynthesis to nitrogen and light were developed and used in a framework that scales from leaf photosynthesis to canopy radiation use efficiency (RUE). This was then used to explore the impact of nitrogen and light dynamics on RUE of cotton canopies. Photosynthetic rate and nitrogen concentration of leaves (specific leaf nitrogen, SLN) were measured from two field experiments in which the rate of nitrogen application was varied. The overall shape of the relationship between photosynthesis and SLN of individual leaves was consistent with that for other species, being described by an exponential rise to a maximum of 32.49 + or - 1.08 [mu]mol CO^sup 2^ m^sup -2^ s^sup -1^. Incorporating the influence of age improved the relationship, showing an impact of leaf age independent of SLN. The photosynthesis relationship developed should be appropriate for use in simulating cotton crops. The approach used to scale from leaf photosynthesis to canopy RUE was effective in capturing the variation in the RUE of cotton as observed in three field experiments. There appeared to be little impact of the ontogenetic changes in light extinction coefficient and vertical gradients of SLN within the canopy on the variation in RUE. For crop simulation purposes, this simplifies the process of modulating RUE in growth models.”
            In this works cited for this article we have: author, publish, and annotation. Therefore, it had enough three criteria for scholarly research article.

Concerns having the ability to furnish the services described herein are requested to give written notification (including the telephone number for a point of contact) to the procuring office above with 45 calendar days from the date of this synopsis. The U.S. Geological Survey, Earth Surface Processes Team, Geologic Division, has a requirement for a portable infrared gas analysis (IRGA) system for field measurements of plant photosynthesis and soil respiration. The equipment required is a photosynthesis system, and soil respiration chamber. The equipment must meet the following criteria: 1. Must be field portable and resistant to a variety of weather conditions. 2. The system must contain IRGA units at the chamber level in the leaf cuvette (chamber that encloses the leaf) and soil respiration chamber. 3.
Scholarly vs. Popular Periodicals
The difference between Scholarly and Popular Periodicals are:
A scholarly periodical (sometimes referred to as peer-reviewed journal or a refereed journal) publishes the results of original and significant research in a particular discipline. A popular periodical (a magazine, newsmagazine, or newspaper) publishes shorter pieces, news items, descriptions or summaries of research findings (but not the original research papers themselves), and/or information of interest to non-specialists or the general public.
For me, I really Proquest, because I can find something such as: citation and annotation easily. Besides that, I also like Scholarly Journal, because almost the authors are Researchers, scientists, scholars. Their writings use the technical vocabulary of the discipline; assumes college-educated reader with some knowledge of the subject.
