Finding Articles in Periodical Indexes



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. Besides that, I have to find cite, and annotation for my topic.

  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)
 Following requirement’s instructor:
The successful search statement you used. Include the actual format as well as any search modes you might have chosen.

Citation for an article in a popular magazine article, and an annotation:
Works Cited
Adler, Tina. "Finding a New Definition of Photosynthesis." Science News Jul 20 1996: 39-. ABI/INFORM Trade & Industry; ProQuest Family Health; ProQuest Research Library. Web. 9 Nov. 2012 .
The annotation for this article:
“Plants may take more than one approach to photosynthesis. Scientists have found that Chlamydomonas mutants' photosynthesis does enable algae to grow.”
            I need to know that “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.”
            I chose this article because its annotation gives me the relation with my research topic; it is photosynthesis.
            Citation for a research article in a scholarly journal, and an annotation:

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.”

Annotation
“Anitra Thorhaug, a fellow scientist who interviewed Dr. Haxo for a paper she wrote, said he was well-known in scientific circles for his research on photosynthesis concepts. During World War II, Dr. Haxo worked on developing sunscreens to protect military personnel from ultraviolet rays in tropical theaters of war.
Dr. Haxo enjoyed going out on the Scripps research vessel Alpha Helix, Thorhaug said. Dr. Haxo was chief scientist on the vessel's maiden voyage to Australia's Great Barrier Reef in 1966, where a group of photo biologists and biochemists studied photosynthesis and pigments in corals and giant clams.
Dr. Haxo was a consultant to several national programs, including the U.S. Committee for the International Biological Program and the President's Science and Advisory Council. He was a fellow of the American Association for the Advancement of Science and the Research Council of the San Diego Zoological Society. After his retirement from Scripps Institution in 1988, Dr. Haxo started researching his lineage and found that one of his ancestors was a general under Napoleon, said longtime friend and colleague Andrew Benson.”
            As you known, most search engines default to Boolean AND logic.
Sometimes you need to search for multiple words to represent a particular concept. To do this, include synonyms or alternate spellings in your search statement and connect these words with Boolean OR logic. OR logic will retrieve Web pages containing one or more of your search terms. Search engines are not consistent in the way they want you to type an OR search. For example, Google requires that OR be capitalized. So, it's usually best to fill out the form on the advanced search page and let the search engine do the rest. Example: war OR peace
For a Boolean NOT search, place a minus sign (-) in front of the word you want to exclude from your search results. Example: war – peace.
Eventually, understanding and using Boolean clearly is your search result.
