1.5 Role of engineers in society

4. 1.1 Society: Definition, Types and Essential Elements
• Classical Definitions of Society: Abstract and Concrete
Many definitions of society; the definitions keeps changing, since
society is dynamic.
• Schaefer and Lamm: the largest form of human group, which
consists of people who share common heritage and culture.
• Ian Robertson: society gives content, direction and meaning
to our lives, and we, in turn, in countless ways, reshape the
society that we leave to the next generation. Society is a
population that occupies the same territory, is subject to the
same political authority and participates in a common culture.
• John F. Cuber: a group of people who have lived long enough
to become organized and to consider themselves and
considered as a unit more or less distinct from other human
units.

5. 1.1 Society: Definition, Types and Essential Elements
• Ginsberg: a collection of individuals unified by certain
relation or modes of behavior, which mark them off from
others who do not enter into these relations or who differ
from them in behavior
• P. Gisbert: a complicated network of social relationships
by which every human being is interconnected with his
fellowmen.
• MacIver and Page: a system of usages and procedures,
authority and mutual aid, of many groupings and
divisions, of controls of human behavior and of liberties.
• A.W. Green: the largest group to which any individual
belongs
Out of these definitions of society, which one do you
consider to be the best? Why?

6. 1.1 Types and Elements of a Society
Types of Society: from evolutionary aspect
• Tribal: hunting and gathering society: hunts for meat,
gathers natural products, do not produce food
• Pastoral: domesticate animals, mostly sheep, goat,
chicken, for meat
• Horticultural: domesticate plants, awareness of plant
from seed, slash and burn
• Agricultural: cultivation of crops, animal energy,
irrigation, saving of seed, feudal, beginning of town
and cities
• Industrial: mechanized production, mass production,
large cities and slums
• Post-industrial: information, communication and
service, generation and analysis of info & knowledge

7. 1.1 Types and Elements of a Society
Basic Elements: Normally societies have following elements:
• People and plurality: society consists of people, of both
sexes, of all ages, of different ideas, race, color.
• Likeness and differences: Members of a society are alike in
many aspects. This “alikeness” bonds them, and they seek
understanding and cooperation from each other. The
members of a society are different in many ways too, like
culture, profession, interest, opinion, views etc.
• Cooperation and conflict: Members of a society cooperate
with each other, and they depend on each other. Yet, due
to differences, conflict exists in a society.
• Stable and dynamic: Society is relatively stable; the norms,
values, and culture are normally stable. Yet, society is
dynamic. Some elements of a society change slowly, and
some change rapidly, depending on external and internal
factors.

8. 1.2 Factors and Classical Theories of Social Change
Factors/Driver/Causes of Social Change
• Physical environment/Contact with other societies:
Physically easily accessible society changes rapidly than
those located in remote (difficult to access) areas
• Information, knowledge and skills: Rate of social change
depends on access to information, ability to put together
the information into knowledge, ability to convert the
knowledge into skills
• Natural causes: Earthquake, landslide, flood,
desertification, and tsunami disintegrate social fabric and
changes society.
• Anthropogenic (Human) activities: International War, Civil
War, displacement for “developmental” activities, industrial
accidents, mass migration

9. 1.2 Classical Theories of Social Change
• Cyclical: ups and downs, birth and death, Oswald Spengler:
approximate 1000 year cycle. Critics of this theory cite
examples that do not follow the 1000 year cycle.
• Evolution: changing with time, getting complex with time,
society continuously develops through time and change.
• Functionalist: changes as required to keep the whole society
functioning, when particular part of a society changes. August
Comte, Herbert Spencer, Emile Durkheim, and Talcott Parsons
propagate this theory. This theory emphasizes on changing role
of different parts of a society to maintain stability of a society.
• Conflict: Karl Marx (19th century) class conflict between haves
and have-nots. Expanded version of conflict theory finds social
conflict between any groups in which the potential for inequity
exists: racial, gender, religions, political, economic, and so on.
Unequal groups usually have conflicting values and agendas,
causing them to compete against one another. This constant
competition between groups forms the basis for the ever-
changing nature of society.

19. 1.5 Role of Engineers in Society
The practice of engineering is directly related to societal issues, and hence
has an impact on society. Engineering is the application of science to solve
societal problems.
Some of the basic roles of an engineering in society are:
• Interact with society to fully understand the societal issues (needs and
problems) and propose a range of short-medium-long term
options/solutions with financial, technical, safety, and environmental
pros and cons of each option
• Contribute in decision making process to choose the best option
• Prepare optimum design, including detailed specification to implement
the designed product
• Execute the solution by creating the product to solve the issue or
supervising the constructing the solution
• Continuously monitor and evaluate the performance of the solution, and
upgrade the solution based on evaluation
• Train people to operate and maintain the solution system for its
reliability and sustainability

20. Changes brought by engineers in societies
• Mass production of goods through mechanization: lower
price of goods
• Automation of production system: standardization of parts
and design, more safety in work place
• Faster means of transportation: easier access to remote
places and faster pace of life, better integration of different
communities
• Mass communication: Awareness enhancement, easier
access to information
• Inventing labor saving devices: faster construction
• Creating faster pace of life: More productivity
• Commercializing recreation: Recreation when wanted
• Emphasizing on high degree of specialization: More reliable
and accurate results
