Chemical Prlstination Guided
Life Origins, iochemist Says
Chemical predestination—and not
chaos' or accident—guided the origin,
evolution_ and reproduction of sub
stances essential to all forms of life,
suggests a biochemist from the Uni
versity.
' "Life chemicals called peptides
could also have been produced in pre
biological times without the help of
nucleic acids, generally considered vi
tal for such reproduction," said Gary
Steinman, assistant pi-ofessor of bio
chernistry. His findings appear in an
article in the August issue of the Pro
ceedings of the National Academy of
Sciences.
Steinman's experiments were de
signe'd to simulate the conditions under
which peptides of biological interest
first appeared on the early Earth. He
found that amino acid building blocks
that 'may have existed' billions of years
ago seem to prefer tol link up in pep-
1 . Architects, Designers' Feud Examined
That years-old, but obscure feud between architects
and interior designers is not, just another American pecu
liarity.
,
The "deep-rooted; misunderstanding" also has plagued
interior designers in ,Western Europe, says David B. Van
Dommelen, associate professor of family housing and home ,
art who has just returned from the International Federa-,
tior of Interior Designers' Congress held in Amsterdam.;
IA truce is the aim of most interior designers; but that;
doesn't seen especially likely.
I"lt's a pretty shabby relationship right now," Van'
Dorimelen said.
I"We have the same probelms here as the European
interior designers," he added.
(Van Dommelen, who is preparing a repbrt on the
meetings for the American Home Economics Association,
said that because -architects are unconvinced that interior -
designers can "relate" to an architect-designed building,
there is hesitancy, to include interior designers during the
planning of a structure.

proach "—the merging of all areas of men's environment

which incorporates both exterior and interior designs—is
often overlooked; and an incongruous completed structure
can result.
Van Dommelen, who attended the three and one-half
day meeting during the summer, said that by discussing
the problems of the architect and the interior designer,
"some headway was made."
Much of the misunderstanding, he said, has developed
because the architect wants to remain "dominant" when
designing a structure.
Nationally known for his books on interiors and in
terior design, Van Dommelen teaches graduate and under
graduate courses in family housing and home art in the
College' of Human Development.

The physically and mentally handicapped are in need
of curriculums that stress social skills as well as vocational
training, two University behavioral scientists emphasize.
Arthur E. GraVatt, associate professor of family rela
,tionships, and Stella R. Goldberg, assistant professor in the
department of child `development and family relationships,
both in the College, of Human Development, conducted a
, nine-month study it Skills, Inc., of Bellefonte, a Penn
sylvania sheltered workshop for handicapped persons to
determine the social needs of these persons.
An„important finding was that more direct and open
discussioi with other` adults is urgently needed to enable
the handicapped to better understand their relations with
others.
The social scientists also found that tabooed topics
such as sexual behavior, contraception, marriage",and par-
enthood, need to be discussed with the handicapped
•
"These people believe they should have an opportunity
to discuss such experiences," said Gravatt, director of the
project. . •
He said that the development of social and community
skills has been overlooked in the past because society felt
it "had to be protected from the. handicapped."
Society also has assumed that handicapped persons
should be protected and sheltered, he added.
In addition to vocational rehabilitation, the study
brought out that the handicapped need more opportunities
to learn by interacting independently with the community

summer to ascertain what adjustment was made by the
handicapped persons involved. Findings showeLthat some

As a result of the project, said Gravatt, Skills, Inc.,
is making instruction in social-community living a perma
ment part of its program along with instruction n home
making for independent living.
Based on the study, also, a special curriculum for
teaching social ;,•• - id community skills will be published in
December. ThOicurriculum, Gravatt said, will be applicable
to educational settings including both secondary schools
and instructions.
The social and community skills program was organized
around the concepts of self, the family and the community.
Dr. Goldberg and Gravatt met with the 20 participants_
weekly at the shelter during the nine-montivperiod. The
program was financed by the Pennsylvania Department of
Public Instruction.
Findings of the project, entitled "A Report on a Demon
stration Project on Social and Community Skills for Re
tarded Youth in a Sheltered Workshop," were presented
by Gravatt at the recent Conference .of the International
Association for the j Scientific Study of Mental Deficiency
at the University of Montpellier, France. •
