Passage 1 lnbmo Hv
In contrast to traditional analyses of minority business, the sociological analysis contends G"y.Z2$
that minority business ownership is a group-level phenomenon, in that it is largely dependent upon jQj,q{eA
social-group resources for its development. Specifically, this analysis indicates that support 9j|gdfb%ml
networks play a critical role in starting and maintaining minority business enterprises by providing KbxR
Lx]w
owners with a range of assistance, from the informal encouragement of family members and `&$B3)Eb
friends to dependable sources of labor and clientele from the owner’s ethnic group. Such self-help P
s R>V)L
networks, which encourage and support ethnic minority entrepreneurs, consist of “primary” #<CIFVH
institutions, those closest to the individual in shaping his or her behavior and beliefs. They are bZipm(e
characterized by the face-to-face association and cooperation of persons united by ties of mutual w36(p{#vp
concern. They form an intermediate social level between the individual and larger “secondary” 'i>xf
^
institutions based on impersonal relationships. Primary institutions comprising the support x|~zHFm6
network include kinship, peer, and neighborhood or community subgroups. k<4
P6?
A major function of self-help networks is financial support. Most scholars agree that minority PoD^`()FR{
business owners have depended primarily on family funds and ethnic community resources for ,|To#umym>
investment capital. Personal savings have been accumulated, often through frugal living habits V{Q kN7-
that require sacrifices by the entire family and are thus a product of long-term family financial {8NwFN.
behavior. Additional loans and gifts from relatives, forthcoming because of group obligation XrN- 2HTV
rather than narrow investment calculation, have supplemented personal savings. Individual G{c#\?12C
entrepreneurs do not necessarily rely on their kin because they cannot obtain financial backing C9KWa*3
from commercial resources. They may actually avoid banks because they assume that commercial (a{ZJI8_
institutions either cannot comprehend the special needs of minority enterprise or charge
CB*/ =Y
unreasonably high interest rates. Dl;d33
Within the larger ethnic community, rotating credit associations have been used to raise :%tuNJjj
capital. These associations are informal clubs of friends and other trusted members of the ethnic .RRlUWu
group who make regular contributions to a fund that is given to each contributor in rotation. One 3q &k
author estimates that 40 percent of New York Chinatown firms established during 1900-1950 d5U; $q{o
utilized such associations as their initial source of capital. However, recent immigrants and third wRVD_?
or fourth generations of older groups now employ rotating credit associations only occasionally to W^xZ+]
raise investment funds. Some groups, like Black Americans, found other means of financial Hq
xK\m%,.
support for their entrepreneurial efforts. The first Black-operated banks were created in the late ~b8a^6:R"
nineteenth century as depositories for dues collected from fraternal or lodge groups, which NJ$e6$g)
themselves had sprung from Black churches. Black banks made limited investments in other Black .C5@QKU
enterprises. Irish immigrants in American cities organized many building and loan associations to F";FG 0
provide capital for home construction and purchase. They, in turn, provided work for many Irish u7muaSy
home-building contractor firms. Other ethnic and minority groups followed similar practices in "T*I|
founding ethnic-directed financial institutions. ){tPP$-i=

Passage2 >{phyByI
It was once assumed that all living things could be divided into two fundamental and %KbBH:z05
exhaustive categories. Multicellular plants and animals, as well as many unicellular organisms, are *i=?0M4S
eukaryotic—their large, complex cells have a well-formed nucleus and many organelles. On the 7JxE|G
other hand, the true bacteria are prokaryotic cell, which are simple and lack a nucleus. The 4w;rl(s
distinction between eukaryotes and bacteria, initially defined in terms of subcellular structures h5LJijJ
visible with a microscope, was ultimately carried to the molecular level. Here prokaryotic and f?/|;Zo4
eukaryotic cells have many features in common. For instance, they translate genetic information ?l)}E
into proteins according to the same type of genetic coding. But even where the molecular dH
^b)G4
processes are the same, the details in the two forms are different and characteristic of the bs<WH`P
respective forms. For example, the amino acid sequences of various enzymes tend to be typically U@o2gjGN
prokaryotic or eukaryotic. The differences between the groups and the similarities within each )![f\!'PI
group made it seem certain to most biologists that the tree of life had only two stems. Moreover, XV74Fl
arguments pointing out the extent of both structural and functional differences between eukaryotes 1?/5A|?V4+
and true bacteria convinced many biologists that the precursors of the eukaryotes must have kGB#2J
diverged from the common ancestor before the bacteria arose. b5iIV1g
Although much of this picture has been sustained by more recent research, it seems Gk{
"O%AE
fundamentally wrong in one respect. Among the bacteria, there are organisms that are t-v^-#
significantly different both from the cells of eukaryotes and from the true bacteria, and it now
o1fyNzq<
appears that there are three stems in the tree of life. New techniques for determining the molecular k7z(Gbzu
sequence of the RNA of organisms have produced evolutionary information about the degree to N:UDbLjw~
which organisms are related, the time since they diverged from a common ancestor, and the zPX=
MfF
reconstruction of ancestral versions of genes. These techniques have strongly suggested that zxk??0]/
although the true bacteria indeed form a large coherent group, certain other bacteria, the ]>VJ--fH
archaebacteria, which are also prokaryotes and which resemble true bacteria, represent a distinct +Op%,,Db
evolutionary branch that far antedates the common ancestor of all true bacteria. /o<}]]YBF
1. The passage is primarily concerned with 9G`FY:(K
