Institutional affiliation of authors

[bosire onyancha <b_onyancha@yahoo.com>]

Dear Colleagues,

I am currently conducting a study on eastern and southern African 
research productivity in HIV/AIDS using Thomson scientific's 
science indicators and some of the entities that I am evaluating 
are authors, institutions and countries as producers of HIV/AIDS 
research in and about E&S Africa. I came across a problem in 
identifying authors based in African institutions. I do not know 
if it is only I who has a problem with such identification. Take 
for instance the following:

AU
Kivihya-Ndugga, LEA
Van Cleeff, MRA
Githui, WA
Nganga, LW
Kibuga, DK
Odhiambo, JA
Klatser, PR

C1  KIT, Dept Biomed Res, NL-1105 AZ Amsterdam, Netherlands.
CRDR, Kenya Med Res Inst, Nairobi, Kenya.
KIT, Royal Trop Inst, Dept Hlth, Amsterdam, Netherlands.
CDC, Nairobi, Kenya.
NLTP, Minist Hlth, Nairobi, Kenya.

In the above example, the record contains 7 authors while there 
are 5 institutions to which the authors belong (are affiliated). 
My problem is: how could one identify the institution, for 
instance, that the first author on the list belongs to? 
Seemingly, there are more than one author who belong to one 
institution. How could one tell who that are? I noticed that 
sometimes the sequencing of authors and that of the institutions 
do not correlate, is that true?
